The technical field to which the invention relates

The invention relates to a lighting unit, the lighting system, which lighting unit, and to the use of such lighting system.

Art

The lighting in the offices is typically provided as a combination of different types of lighting systems. For example, fluorescent lighting mounted on the ceiling, as General office lighting, table lamps are used to provide individual coverage for individuals working at a Desk, and other halogen lighting mounted on the ceiling or on the wall, for providing spot lighting paintings hanging on the wall. Thus, it can be provided the light having several different profiles lighting, both functional and decorative kinds, and/or as General lighting and individual lighting. Most types of lighting systems are once established, fixed installation, but in recent years also been suggested once installed, the adjustable settings that allow you to adjust the profile of the lighting. Some separate, stand-alone lamp can be adjustable, such as table lamp.

An example of such a separate adjustable lamp described in the application US 2003/0193802 A1 PA�UNT USA. This document describes the system of diode light sources for the stage, theatre and architectural lighting that includes a plurality of individual flat panels intended for installation of a plurality of LEDs, emitting many rays of light diodes in a common area of focus. The case containing these panels has a Central base portion and a circular rim defining the opening in the housing, aligned with the plane of the circular rim having a center plane of the rim, is arranged transversely to the axis aligned with the Central base portion. Screw the layout sets the position of the panels in a variety of selected positions, where each panel is oriented at a selected angle relative to the axis and are grouped diodes emit beams of light diodes transversely to each individual panel.

Summary of the invention

The lack of a separate adjustable lamps described in the application US 2003/0193802 A1 patent USA, may, for example, consist in the fact that adjustment of the lamp may be rather time-consuming and/or inconvenient, since the adjustment of the orientation of the panels relative to the axis requires a mechanical adjustment screw layout, while adjusting the light intensity of the emitted rays of light diodes requires adjustment electrical operating conditions, such as current flowing through the diode� light sources. Thus, there may be a need to provide an adjustable lamp and in the more General case of an adjustable lighting system, which provides a more simple adjustment.

The drawback of many of the systems of the prior art may, for example, consist in the fact that adjustment requires adjusting many parameters that can be not only time consuming and/or inconvenient for the user, but can also be associated with a high degree of complexity (electrical) connections of all components and/or with a large number of electrical connections, i.e. a complex layout.

Thus, there may be a need to provide a flexible lighting system, which the user could easily adjust and/or which would be simple to install and maintain, for example, with a reduced complexity (electrical) connections.

To this end, the invention provides in a first aspect, a lighting unit (1) containing at least two springs (20) light secured, at least two carriers (10) and the actuator (40) in which:

a. each source (20) of light are arranged with the possibility to generate while using the appropriate beam (In) light, the light intensity of which depends on the signal (I; V) electric power;

b. the actuator (40) is arranged with at�zmoznostjo to focus while using the appropriate beam (rays) (B) of light in the orientation, depending on the signal (I; V) electric power; and

c. the orientation of each beam of light has a predetermined relationship with the light intensity of the light beam,

d. the actuator is arranged with the possibility of mechanical impact, at least two of the carrier (10) for orientation of the corresponding beam (rays) (In) light.

The advantage of the lighting unit in accordance with the invention can consist in that the lighting unit is easy to control because the control signals of the electric power leads to a corresponding control light intensity, and orientation of the light beam. In particular, the degree of orientation, such as the degree of concentration of the rays of light, when plenty of light is provided by the lighting unit may correspond to the light intensity of the beam (rays) of light, so that, for example, an increase in the intensity of light for illumination of the workplace can be directly related to the direction of the light beam to the workplace.

Another advantage of a predetermined relationship between the orientation and the intensity of the light beam may be that the user does not need to ponder or to experimentally determine which orientation corresponds to a certain intensity of light, as lighting� unit provides a suitable orientation, which corresponds to the intensity of light.

The term "signal electric power" may refer to a signal of electrical power used to operate the light sources to generate light beam with the light intensity, for example (continuous or pulsed) current (DC or pulsed) voltage. The signal electric power can enter from the outside into the lighting unit or, alternatively, may be formed inside of the lighting unit, for example, as a result of converting externally supplied signal power, or from an internal power source.

The term "transmission" may refer to a device made with the possibility of exposure to the light source to guide the light beam, either through direct connection with the source of light (e.g., light source, which is mounted directly on the drive), or indirectly through a mechanical connection.

The term "orientation" may refer to the orientation relative to the reference direction, such as the angle relative to the normal to the reference plane, or may, for example, relate to the direction of the light beam at the target, for example at your workplace. In particular, when many rays of light provided by one or more lighting units, the orientation of these rays of light�and can match to ensure the concentration of light on the target by directing all or a subset of the light rays toward a common goal. It can also be called the focusing of rays.

The term "predetermined relationship" may refer to the orientation of the light beam and the light intensity of the light beam, which are functionally interconnected with each other, in particular, in one-to-one relationship. Each installation of the light intensity detected by the signal of electrical power, thus, refers to a particular orientation. The change of light intensity by changing the signal of electrical power, thus, leads to a corresponding change in the orientation caused by the same signal electric power. Predetermined relationship may be a once a connection that cannot be modified. Predetermined relationship may correspond to a user-selected predetermined relationship selected by the user, e.g., using a remote control or other type of user interface, from a plurality of predetermined relationships (which can also be called as presets).

As will be clear to a person skilled in the art, implementation options can be combined.

In a variant implementation of the lighting unit may further contain vyvoditsya, which is electrically connected to the source of electrical power, and which is arranged with the possibility of filing while using the electrical power signal.

The term "output power" can refer to one or more electrical connections arranged with the possibility of connection with an external power source and for supplying a signal electric power to the light source and the actuator. Thus the lighting unit shall not include the power source, thus reducing, for example, the cost of the lighting unit and/or the total number of installations of lighting, when used many such lighting units connected with a single power supply. The power output can directly accept the signal electric power from an external power source. Alternatively, the output power can be electrically connected to an external power supply through a transformer, wherein the transformer receives the incoming power from an external power source and converts it into an electrical power signal, and delivers the electrical signal power to the output power. For example, the power source may be a standard signal AC power consumed by the network, which weakened to, for example, signal pita�Oia with slice-of-phase using a standard dimmer such as a TRIAC-dimmer; a transformer to convert the power signal with the cutoff for the phase b signal electric power received by the power supply pin. In the embodiment of the power output is a connector, such as electric plug for a power source, such as a socket.

In the embodiment of the electrical power signal is a current.

The light source and the actuator, thus work depending on current. Current can, for example, a constant current, wherein the current level determines the intensity of the light beam generated by the light source, and the orientation of the light beam, which is provided with a drive. The current may be, for example, the current pulse width modulation with a fixed level of current, the width of the pulse determines the light intensity of the light beam generated by the light source, and the orientation of the light beam, which is provided with a drive. Current, alternatively, may be a current pulse width modulation, the level of current which can also be controlled, whereby the light intensity and orientation are determined by the pulse width and level of the current.

In accordance with an additional option is p�effect to the light source and the actuator are electrically connected in series as a serial arrangement, in which sequential arrangement arranged to receive, during use, current (I). Incremental linking may be electrically connected with the power output, for connection to a source of electrical power for receiving current during use. The light source and the actuator, thus, connected to receive the same current.

In the embodiment of the electrical power signal is a voltage. The light source and the actuator, thus, depending on the voltage.

In accordance with an additional variant of implementation of the light source and the actuator are electrically connected in parallel, in a parallel arrangement, in which parallel arrangement is arranged to receive in use voltage (V). The parallel configuration can be electrically connected to the power supply pin for source connection of the power supply, for receiving the voltage during use. The light source and the actuator, thus, connected to receive the same voltage.

In a variant implementation, the light intensity depends on the average signal electric power. A signal of electrical power, thus determines the intensity of light on its average level of the signal which may, for example, be essentially �proportionally average level of the signal.

In a variant implementation of the orientation depends on the average signal power of the power supply. A signal of electrical power, thus determines the orientation of its average power, which may be, for example, proportional to the time average of the square of the current. Average power may, for example, relate to the internal power dissipation in the drive in which power dissipation determines how the drive acts on the orientation of the light beam.

In a variant implementation, the light intensity depends on the average signal electric power, and the orientation depends on the average signal electric power. A signal of electrical power, thus determines the intensity of light as well as the orientation of the light beam on its average level of the signal. Predetermined relationship may thus, for example, correspond to a linear relationship between light intensity and orientation.

In yet another embodiment of the intensity of light depends on the average signal electric power, and the orientation depends on the average signal electric power. A signal of electrical power, thus determines the intensity of light according to the average signal level and the orientation of its average power. For example, when the signal electric Pete�tion represents the current a predetermined relationship, therefore, may, for example, correspond to a quadratic relationship between light intensity and orientation.

In a variant implementation, the light source comprises at least one light emitting diode (LED). Solid state LED as the source (s) of light are especially in demand because of their small size, low weight and narrow rays.

The light source is provided on the carrier and the actuator are arranged with the possibility of mechanical impact on the media orientation of the light beam. The term "carrier" can refer, for example, to a printed circuit Board on which is provided electrical signals to signal electric power to the light source, which are mechanically interact with the actuator when the actuator is actuated by a signal of electrical power. The carrier can be mechanically reliable and tough. This may provide the advantage consisting in that the actuator acts on a reliable mechanical media, and not directly on the relatively fragile light source. The carrier can carry multiple light sources. The carrier can also be formed as a cable, pipe, lath, panel, etc. the Term "carrier" can refer to a flexible surface, which is arranged to give it different shapes, and with electric minimizeall to signal the power supply to the light source, in which the flexible surface is formed as a result of mechanical interaction with the drive when the drive is actuated by a signal of electrical power.

The lighting unit includes multiple light sources provided on multiple media, in which the actuator is arranged with the possibility of mechanical impact on a variety of carriers, for orientation of the corresponding beam (rays) of light. A single drive may, therefore, preferable to work on a variety of carriers for simultaneous orientation of the respective light rays, for example, the concentration of the respective light rays at a common point. In a single actuator may, for example, be provided with a variety of carriers arranged, for example, in the form of a hexagon, and is arranged to affect the Central point of many medium, such as a hexagon, to change the degree of focusing the respective light beams. It may be preferable to reduce the complexity and/or cost of the lighting unit. In a variant implementation of the lighting unit contains a variety of carriers, at least some of the plurality of carriers contain many LED.

In a variant implementation of the actuator contains a bimetallic element actuator made with the possibility of orientation in time use of the light beam depending on the signal electric power. The bimetal element of the actuator can be mechanically connected with the carrier and, thus, can affect the carrier to guide the carrier and, thus, of the light beam. Bimetallic element actuator can provide a convenient and/or easy drive, which is directly actuated by a signal of electrical power. The bimetal drive element, in particular, can be configured for heating by means of a signal of electrical power up to a certain temperature and orientation of the light beam depending on the temperature of the bimetal drive element.

In an additional embodiment of the light source is provided on the bimetal element of the actuator. Thus, the bimetallic element actuator moves the light source, in which the bimetallic drive element preferably can be configured to directly Orient the beam of light generated by the light source. In particular, the bimetallic element actuator may be arranged in thermal communication with the light source. The light intensity of the light beam can then be directly determined based on the electric signal fed to the light source, whereas the orientation of the light beam is determined by the electric signal fed to the light source h�RES heating of the light source, generating a beam of light, resulting in changing the shape of the bimetallic element actuator. Such heating is usually proportional to the average signal power of the power supply. Additional variant of implementation, therefore, it is preferable to provide a relatively simple and/or reliable lighting unit in which both the intensity and orientation of the light beam is determined by the electrical power signal in accordance with a predetermined relationship.

In another embodiment of the actuator includes an Electromechanical solenoid, which is arranged with the possibility of orientation during use of the light beam in orientation depending on the signal electric power. Electromechanical solenoid may be mechanically connected with the carrier to guide the carrier and, thus, of the light beam. Electromechanical solenoid, thus, can provide a convenient alternative and/or a simple actuator which is directly actuated by a signal of electrical power. The electrical power signal may, in particular, to generate mechanical force in Electromechanical solenoid, a mechanical force which may be approximately proportional to the level of current, when the electric signal represents the power sobiek, and this mechanical force can act on the carrier to guide the carrier and, thus, the orientation of the light beam. Electromechanical solenoid may, in particular, contain the core in electromagnetic coupling with the electromagnetic induction coil, wherein the Electromechanical solenoid is arranged with the possibility to position the core relative to the electromagnetic induction coil depending on the electrical power signal for orienting the light beam.

In another embodiment of the actuator includes a piezoelectric element arranged with the possibility of orientation during use of the light beam in a certain orientation depending on the signal electric power. The piezoelectric element may, therefore, provide a convenient alternative and/or a simple actuator which is directly actuated by a signal of electrical power. The electrical power signal may, in particular, to generate strain in the piezoelectric element, the deformation of which can be approximately proportional to the voltage level when the electrical power signal is a voltage, and this deformation can act on the carrier to guide the carrier and, thus, the orientation of the light beam.

In a variant implementation of the lighting unit supplementary�contains an additional source of electrical power, linked with the ability of the electrical power signal. The lighting unit can thus be operated independently from the external source, and/or a source of electrical power may be combined with the possibility of setting signal of the electric power supply from the externally supplied external signal source, for example, by converting externally supplied external signal source into a signal of electrical power. A signal of electrical power, thus, for example, can be scaled in accordance with the characteristics of the lighting unit, while the signal is used for an external source, which can be achieved by standard means, as, for example, the signal is AC, which weaken using a standard voltage regulator, for example, based on the TRIAC.

In a second aspect of the invention is provided a lighting system containing at least one lighting unit in accordance with the invention, in particular a multitude of lighting units in accordance with the invention. Many lighting units can work together from one electrical power signal, or, alternatively, for example, they can be provided with respective separate signals electrical power. The advantage of the system �of svedeniya in accordance with the invention can be what lighting system you can easily manage, as the control signal (signals) of electrical power leads to a corresponding control light intensity, and orientation of the beam (rays) of light. In particular, the degree of concentration of multiple light beams from multiple light beams may be provided by the lighting system in accordance with the intensities of the light beam (rays) of light in such a way that, for example, an increase in the intensity of light for illumination of the workplace can be directly related to the direction of the light beam to the workplace, using a subset of the plurality of lighting units, while other lighting units may have the rays of light to moderate intensity of light at essentially the diffused light to illuminate the area around your workplace.

In a variant implementation of the lighting system further comprises a source of electrical power in electrical communication with the set of lighting units and configured with the ability for multiple lighting units of the signal electric power. The source of electrical power may be combined with the possibility of one of the electrical power signal, determining, therefore, the total intensity of light and the overall orientation of the light rays generated by�x lighting units. The source of electrical power may be combined with providing a lot of signals of electrical power to a plurality of lighting units, determining, therefore, the individual light intensity and the corresponding orientation of the rays of light generated by each of the lighting units. Lighting units can be placed in groups and each group receives a signal of electrical power, which determines the light intensity and the orientation of the rays of light generated by the lighting units for the group.

In the above description, the term "multiple light sources", such as "lots of LEDs", may refer to 2 or more light sources, in particular 2-100000 light sources, for example 2-10000, such as 4-300, for example 16-256. Therefore, a carrier, a lighting unit or lighting system may comprise a plurality of light sources such as LEDs. In General, the media or, more specifically, the lighting blocky or lighting system may include light sources such as LEDs, with a density of 2-10000 light sources/m2in particular 25-2500 light sources/m2while the density is measured relative to the total area, is covered with a lighting unit or lighting system. It should be noted that many sources of light�and, such as multiple LEDs, can be spread across multiple media. The term "lighting system" also can refer to a variety of lighting systems.

The light source may include any source of light, such as a small incandescent lamp or a fiber tip or fiber heterogeneity (arranged to let light out of the fiber; this variant implementation has the advantage of relative cheapness), but may, in particular, contain an LED (light emitting diodes) as light source). A particular advantage of using LED is that they are relatively small and therefore can be combined in large numbers. Another specific advantage of using LED is that they can provide a relatively narrow beams that allows accurate determination of the profile of light generated by the lighting system. The term LED may also refer to OLED, but, in particular, relates to a solid-state light sources. Unless otherwise specified, the term LED in this document further relates to solid-state LED.

In the embodiment of the LED is provided with a density of at least 1 LED per 100 cm2. In an additional embodiment of the LED is provided with a density of at least 1 LED per 10 cm2. In a variant implementation of the many elements�tov is at least 20. In a variant implementation of the set of elements contains in total at least 100 light sources. With such relatively high density, the high number of elements and/or with the high number of light sources is achieved a significant degree of flexibility. In addition, a large number of LED allows you to use the LED with a relatively low scattering power, which may be preferable from the point of view of thermal performance. It should be understood that the number of LED used in the lighting system may be determined based, for example, from the required level (s) light type and characteristics (such as the output level of light, color of light, thermal characteristics and/or electrical performance parameters) LED and the required degree of flexibility profile of light generated from the lighting system.

The third aspect of the invention provides the space containing the lighting system in accordance with any one variant of implementation of the second aspect of the invention. The space may be, for example, room, office, hallway, corridor, production room, hospital room or any other space in which the regulation of lighting conditions without having to reinstall lighting system in whole or in part, would be desirable. Space, in particular, can�t imagine a space with multiple workspaces with individual lighting requirements. When such a space contains a lighting system in accordance with the invention, all workspaces can be optimally illuminated without the need for any re-installation and without the need for additional fixtures, such as table lamp. In additional embodiments, the lighting system put together for the lighting of the wall from space. This eliminates the need for additional lighting units to illuminate the perimeter of the wall and may provide a consistent profile lighting throughout the space. In a variant implementation of the lighting system provides the profile of the light through a predetermined time period from the first profile to the second lighting profile lighting. This change can be repeated, providing a gradual cyclical transition between two or more profiles lighting.

In a variant implementation of the lighting system fixed to the ceiling space. The lighting system may be attached directly to the ceiling or, alternatively, suspended from the ceiling.

In an additional embodiment of the lighting system further comprises a controller which can be arranged externally relative to the ceiling, but which can also be�triplets at the ceiling, and which is arranged to control the lighting system and, in particular, individual lighting units of the lighting system. Thus, there may be provided a profile of illumination, which, for example, is different at different times of day, depending on the number of office workers and their provisions, and/or depending on the activities indoors (e.g., in different ways for meetings and independent work). For example, the intensity profiles and the illumination light generated by the lighting system can be variable, and can be managed by the controller. In addition, the intensity profile and coverage may depend on the sensor signal from the sensor (such as a touch sensor, a sensor (daylight) lighting or approximation), wherein the sensor is arranged with the possibility to perceive the object or room, and in which the controller is arranged with the possibility to control the intensity profile and the lighting depending on the sensor signal. For example, the controller can provide special coverage of the workplace in the premises, over and above the coverage has a relatively high intensity and profile illumination, suitable release profile of the workplace, when human presence is detected in the workplace sensor, while it ensures�AET General lighting with relatively moderate intensity and profile illumination, the corresponding scattered and/or uniform profile in other cases. The controller also may be a remote control.

In still another embodiment, one implementation of the invention provides a lighting system in combination with the sensor and the controller, in which the sensor is arranged with the possibility of providing a sensor signal when the sensor is close to, or touch it, and in which the controller is arranged with the possibility to control the lighting system.

The term "controller" can also refer to a variety of controllers. In particular, many controllers can be used for larger units or systems. In an embodiment, the implementation of a variety of controllers configured to control a subset of a plurality of rays of light.

A fourth aspect of the invention provides the use of the lighting unit in accordance with the invention, in which use includes the establishment and training of the signal electric power of the lighting unit to generate a light beam with a predetermined intensity and a predetermined orientation. The use provides a convenient way to install, modify, or determine the profile of the lighting combined with the intensity and orientation of light.

A fifth aspect of the invention provides �use the lighting system in accordance with the invention, moreover, the use contains the stages at which generate a lot of light rays comprising one or more first light beams, and one or more second beams of light in which

one or more first light beams have a first predetermined intensity and a first predetermined orientation associated with providing General lighting General light level, and orientation corresponding to a scattered light generated depending on the first signal of the power supply; and

one or more second light beams have a second predetermined intensity, and a second predetermined orientation associated with the provision of directed illumination level of a directional light is preferably greater than the level of total light generated depending on the second electric signal.

The use of the lighting system, thus, can provide, for example, the profile of lighting that is associated with the concentration of the light generated by the light sources, the plurality of lighting units of the lighting system for multiple workspaces. Workspaces can, for example, to conform to office desks in the office, jobs in the workshop or individual working areas in production�om the room. The lighting may be further associated with the provision of light for General illumination. The provision of a profile can be associated with deconcentrating light generated by the light sources, the plurality of lighting units. This helps to ensure absently lit area, for example, corresponding to the corridor or open area, for example, in the office, in the Studio or in the production room. The security profile can be associated with slow changes in the pattern of illumination during a predetermined time period from the first profile lighting on the second profile lighting.

The lighting system can thus be used to determine the profile of lighting in the space. For example, one or more parts of space can, thus, be provided with concentrated light generated by the light sources from the plurality of lighting units; preferably lots of parts provided with concentrated light. One or more parts of space with concentrated light, thus, may be provided, for example, in different positions and at different moments of use of the lighting system. In space, therefore, can be provided, for example, one or�many regions in space, where light generated by the light sources from the plurality of lighting units, will be deconcentrated, providing, thus, scattered of the illuminated region in space. One or more parts of space with a concentrated light may be associated, for example, with workspaces in the workspace.

In an additional embodiment of the use of the lighting system, alternately or in addition, provides light directed towards the wall space, to generate perimeter lighting, without the need to install additional sources of light for wall lighting. Wall lighting using the same lighting system that is used for General lighting and task lighting, it may be preferable to determine a continuous profile of lighting throughout the space.

The term "green light", in particular, relates to light having a wavelength in the range of about 500-570 nm. The term "red light", in particular, relates to light having a wavelength in the range of approximately 590-650 nm. The term "yellow light", in particular, relates to light having a wavelength in the range of about 560-590 nm. Those�min "light" in this description, in particular, refers to visible light, i.e. light having a wavelength selected from the range of about 380-780 nm. Emitted light from the ceiling into the space under the ceiling, in this description can also be designated as "ceiling light". Light emitted from the ceiling on the wall near the ceiling, in this description may be called the "ceiling light" or "light wall lighting".

Unless otherwise specified, and in the case where it is applicable and technically feasible, the phrase "selected from the group consisting' of many elements, can also refer to a combination of two or more of the listed items. Terms such as "below", "above", "up" and "down" refer to existing provisions or arrangements of elements that could be obtained, if the lighting system was composed essentially flat relative to, in particular, lower, essentially horizontal surface, with the lower surface of the lighting system, essentially parallel, essentially horizontal surface and facing away from the ceiling into the room. However, this does not preclude the use of lighting systems in other layouts, such as on a wall, or other (e.g., vertical) layouts.

Detailed description of the invention

Fig. 1a schematically shows an exemplary embodiment of the lighting unit 1 in accordance with the invention. The lighting unit 1 is fixed to the ceiling (not shown) of office space (not shown). The lighting unit 1, alternatively, can be provided as a separate lighting unit, for example as a table lamp or a lamp mounted on the wall. Fig. 1 shows a workstation 2 in the office space. The workplace has, as Prim�RA, table 3 from the chair 4 and the computer display device 5 on the table.

The lighting unit 1 has a plurality of holders 11 designated private rooms s11, s12, s13. The holders 11 drawn so that they continue down from the ceiling, and also you can call them pendants 11, but they can be installed directly on the ceiling or can be embedded in the ceiling.

Two elements 10, separately denoted as e11-12, e12-13, is connected with the adjustable holders s11, s12, s13, using the adjustable connections 12: element s11-12 combines with two holders s11 and s12, and the element e12-13 connects with two holders s12 and s13. The term "adjustable compound" is used to denote a connection between an element and a holder which is adjustable; in particular, the element may be hinged to or pivotally connected to the holder. Each of these two elements 10 includes a source 20 of light to provide a beam B of light, the intensity of which depends on the signal of electrical power (not shown). The signal electric power can be fed from outside into the lighting unit 1 or, alternatively, it can be provided from the source of electrical power, built-in lighting unit 1 or, alternatively, he may be granted conversion from electric�th power in the lighting unit 1 of the signal of the power source, supplied from the external power source 30 via the output 50 power, as indicated by the dotted line. The elements 10 may be referred to as the carriers 10, where the word "media" highlights the fact that the source (s) 20 of the world is transferred (migrated) media (media) 10. In this example, the source 20 of light contains many separate sources L1, L2 and L3 of the light to ensure the beams B1, B2 and B3 of the light, which together can form a beam B of light. Sources L1, L2, L3 of the light can, for example, be LEDs.

Holder s12 is provided to the actuator 40, which is arranged to control the orientation of the elements e11-12, e12-13, depending on the signal of electrical power (not shown): the first orientation, shown schematically by dashed lines, corresponds to the orientation of the elements 10 in the same plane, and corresponds to the light rays shown by dotted lines, which emit light essentially at a right angle from the ceiling towards the floor 6; the second orientation, shown schematically in solid lines, corresponds to the elements 10, which are oriented at some angle, and corresponds to the light rays, shown in solid lines, oriented in the direction of the working space 2, light rays provide concentrated light for target illumination.

Lighting unit, thus, can provide power�acivate target workstation lighting 2 by focusing elements e11-e12 and el2-13 at angles relative to the respective holders s11, s12 and s13, directing, thus, the beams generated by the light sources, the elements of the workplace 2, that is, by focusing the rays of light from the elements e11-e12 and e12-13 in the direction of the working space 2, as shown in solid lines. Light emitted from the elements e11-e12 and e12-13, therefore, focuses on the workplace 2. Rays of B light provided by the source 20 of light on the elements e11-e12 and e12-13, have a relatively high light intensity (which is also referred to as brightness). The intensity of the light rays of B light has a predetermined relationship to the orientation of the light beam: when the orientation corresponds to a high degree of concentration, the light rays have a greater intensity of light, providing, thus, suitable conditions of illumination for task lighting; whereas the light intensity is moderate, when the orientation corresponds to a low degree of concentration, i.e. a flat profile lighting, providing, thus, suitable conditions of illumination for General lighting, usually associated with diffused light. The intensity of the light may, for example, be essentially proportional to the degree of concentration, which may, for example, be parametrisation angle between the carrier 10 and the plane parallel to the ceiling. Lighting unit, as an alternative, one can control�ive to provide General illumination workplace 2, focusing elements e11-e12 and e11-12 is essentially perpendicular to the respective holders of s11, s12 and s13, i.e., essentially parallel to the floor of the office, as shown by dotted lines. The light intensity of the respective light beams is moderate in orientation corresponding to a low degree of concentration to ensure suitable conditions of illumination for General lighting, in particular, essentially ambient lighting. Profile lighting can, thus, be identified and/or controlled using the lighting unit 1 by at least the controlled orientation of the two elements e11-12, e12-13 relative to the respective holders s11, s12, s13, orienting, therefore, the respective rays of light and adjusting the intensity of light of the respective light beams in accordance with a predetermined relationship with their respective orientations. The profile definition can be associated with the concentration of the rays of light generated by sources L1, L2, L3... light on two elements e11-12, e12-13, for example, in the working area 5. As will be clear to a person skilled in the art, the invention is not limited to the elements 10 and/or the holders 11 and/or 10 sources of light in the form of multiple sources L1-L3 of light, etc., showing�granted on the schematic drawings.

Fig. 1b shows a bottom view of an exemplary lighting unit 1. The lighting unit 1 is a unit in the form of a hexagon, having layout in the form of a star consisting of many elements or carriers 10, each of which carries a variety of sources 20 light and which can be connected with adjustable holder 11. The carriers 10 may be made in the form of strips, as shown. As shown, the leftmost holder 11 may correspond to, for example, the holder of the s11 of Fig. 1a, the average holder 11 can match the holder s12 in Fig. 1a, the right-holder 11 may correspond to, for example, the holder s13 of Fig. 1a, and the corresponding two elements 10 can correspond to the elements e11-12, e12-13 in Fig. 1a. The line Ia-Ia drawn to denote the cross section of Fig. 1b, which corresponds to the drawing plane of Fig. 1a. In this example, each carrier 10 carries three light source in the form of, for example, three LEDs, white light, and the lighting unit 1 has six media 10.

It should be understood that other sets of carriers 10 are also possible within a single lighting unit, such as two, three, four or even a lot more. It should be understood that other multiple sources 20 light on the carrier 10 are also possible depending, for example, from the type of light source, size�s carriers 10 and intended use of the light source (for example, in determining the distance between the lighting unit 1 and a work space 2, which may be called the height or ceiling height).

All media 10 is connected through an adjustable connection at the outer end (with respect to composition in the form of a star) carriers with fixed holders 11 and their other ends to the actuator 40, secured on the holder 11 in the center of the composition in the form of a star. Thus, in this schematically shows a variant implementation of all media 10 together are driven by an actuator 40 for joint orientation change of the generated light rays, in particular, to change the degree of concentration of the generated light. In particular, when light rays are high intensity, light rays from all six of the elements 10 are oriented to provide a highly concentrated profile lighting, such as high brightness, essentially, focused spot lighting in the workplace. When rays of light are of moderate intensity, rays of light from all six elements are emitted essentially parallel to each other, providing, thus, indirect lighting suitable for General illumination.

Fig. 1c shows a bottom view of an alternative exemplary lighting unit 1. The lighting unit 1 is a unit in the form above�of topolnica, having layout in the form of a star consisting of many elements or carriers 10, each of which carries a variety of sources 20 light, and is connected with the possibility of adjustment with the holders 11. This variant implementation differs from the variant implementation, shown in Fig. 1b in that the carriers 10 essentially have a triangular shape and are connected with two adjustable connections to the two corresponding edges of the triangle at the outer ends of the lighting unit 1 in the shape of a hexagon, but also as the embodiment of the implementation of Fig. 1b, the carriers are connected together at their other ends to the actuator 40, secured on the holder 11, in the center of the composition in the form of a star. The layout of Fig. 1b could allow a greater number of sources 20 light on the media 10, the arrangement of Fig. 1a, and/or provides a more uniform distribution of sources 20 light on the area covered by the lighting unit 1.

Fig. 1d shows a bottom view of another alternative exemplary lighting unit 1. The lighting unit 1 is a block rectangular in shape and has a layout in the form of two rows of the plurality of elements or carriers 10, each of which carries a variety of sources 20 light. Layout in two rows contain pairs p1, p2, p3, p4 elements 10 are connected with the possibility to regulate�of the holders 11. Left the carriers of each pair are aligned in the first row r1, the right-wing media of each pair are aligned in a second row r2. This version of the implementation differs from the variant implementation, shown in Fig. 1c, so that the shape of the lighting unit 1 is rectangular, and that the media 10 is essentially rectangular and is connected to the adjustable joints at the outer edge of the lighting unit 1 in the form of a rectangle, and they are connected together at their inner adjacent edges of the actuator 40, secured on the holder 11 on the center line of the layout in two rows. The layout of Fig. 1d is arranged to provide uniform illumination at a moderate intensity, as a result of the orientation of all of the media 10 in the plane, whereas the concentration in the form of lines of light rays of high intensity can be achieved by orientation of the two rows r1 and r2 at some angle to each other, as shown in Fig. 1a, which corresponds to the cross section along the line Ia-Ia.

Fig. 2 schematically shows an alternative exemplary variant of implementation of the lighting system 100 in accordance with the invention, fixed to the ceiling (not shown) of office space (not shown) and contains a variety of lighting units 1. Fig. 2 shows two workstations 2, 8 in different positions on the floor 6 OFI�and office space, separated by a corridor 7. Every workplace has, as an example, table 3 from the chair 4 and the computer display device 5 on the table.

The lighting system 100 may include a plurality of holders 11, individually numbered, s11, s12, s13, s14, s15, s16, s17. The holders 11 can be arranged on a grid (not shown) and continue down from the ceiling, or can be directly attached to or embedded in the ceiling. It should be understood that the grid can continue in two dimensions along the ceiling. The grid may, for example, correspond to a triangular or hexagonal lattice.

Elements 10, separately denoted as e11-12, e12-13, e13-14, e14-15, e15-16, e16-17, connected with the possibility of their regulation on the holders s11, s12, s13, s14, s15, s16, s17 with adjustable connections 12: element s11-12 is connected to the two holders s11 and s12, the element e12-13 is connected to two holders s12 and s13, etc., Each of the elements 10 includes a source 20 of light to provide a beam B of light certain light intensity depending on a signal of electrical power (not shown). Signals of electrical power can be provided externally (e.g., from an external power source 30) to lighting units 1 through 50 conclusions power or, alternatively, may be provided from one or more sources 30 electric�th power, built-in lighting unit 1, or, alternatively, may be guaranteed by one or more transformations of the electric power supply to the lighting unit 1 of the signal source power supplied from an external source 30 via terminals 50 power, as indicated by the dotted lines. And again, the elements 10 can also be called the media 10, in which the word "media" highlights the fact that the sources 20 light are carried by the media 10. In this example, the source 20 of light contains many separate sources L1, L2 and L3 of the light to ensure the beams B1, B2 and B3 of the light, which together constitute a beam B of light. Sources L1, L2, L3 of the light can, for example, be LEDs. In the example shown on the holders s12, sl4 and sl6 are provided corresponding to the actuators 40, which is arranged to control orientation of the elements e11-12, e12-13, elements e13-14, e14-15 and elements e15-16 and e16-17.

The lighting system 100 can be provided as a plurality of lighting units 1: the first lighting unit contains elements e11-e12 and e12-13, and their corresponding common actuator 40, running from the first electrical power signal, the second lighting unit contains elements e13-e14 and e14-15 and their corresponding (common) actuator 40, running from the second electrical power signal, and the third lighting unit contents�t elements e15-e16 and e16-17, and their respective (common) actuator 40, running from the third signal electric power. The lighting system 100, alternatively, can be provided as a single lighting unit that contains all the elements e11-12, e12-13, e13-14, e14-15, e15-16 and e16-17, powered by three signals of electrical power to three respective actuator connected to the elements e11-el2 and e12-13, elements e13-el4 and e14-15 and elements e15-e16 and e16-17, respectively.

The system 100 lighting can provide task lighting at the working place 2 by focusing elements e11-e12 and e12-13 at angles relative to the respective holders s11, s12 and s13, directing, thus, the beams generated by the light sources on the elements in the working space 2, that is, by focusing the rays of light from the elements e11-e12 and e12-13 in the direction of the workplace 2. Light coming from the elements e11-e12 and e12-13, therefore, focuses on the workplace 2. Rays of B light provided by the source 20 of light on the elements e11-e12 and e12-13, have a relatively high light intensity (which is also referred to as brightness). The intensity of the light rays of B light has a predetermined relationship to the orientation of the light beam: when the orientation corresponds to a high degree of concentration, the light rays have high intensity lights, providing, thus, suitable conditions� lighting, for example, task lighting, when the light intensity is moderate, when the orientation corresponds to the low degree of concentration, i.e. a flat profile lighting, providing, thus, suitable conditions of illumination for General lighting, usually associated with diffused light. The light intensity can be, for example, is essentially proportional to the degree of concentration, which may, for example, be parametrisation angle between the carrier 10 and the plane parallel to the ceiling. Similarly, the lighting system provides task lighting for the workplace 5, by positioning elements e15-e16 and e16-17 at angles relative to the respective holders s15, s16 and s17, directing, thus, the beams generated by the light sources on the elements at your workplace 5, that is, by focusing the rays of light from the elements e15-e16 and e16-17 in the direction of the workplace 5. Lighting system additionally provides General illumination on the part of the office space in the example of Fig. 2 corridor 7, by focusing elements e13-el4 and e14-15, essentially perpendicular to the respective holders s13, s14 and s15, that is, essentially parallel to the floor of the office. The light intensity of the respective light beams is moderate, with an orientation corresponding to a low degree of concentration to provide�of suitable lighting conditions for General lighting, in particular, in substance, diffused light. Profile lighting, thus, may be determined and/or adjusted using the illumination system 100 through at least the controlled orientation of at least two of the plurality of elements e11-12, e12-13, e13-14, e14-15, e15-16, e16-17 relative to the respective holders s11, s12, s13, s14, s15, s16, s17, orienting, thus, respective rays of light and adjusting the intensity of light of the respective light beams in accordance with a predetermined relationship with their respective orientations. The profile definition can be associated with the concentration of the light generated by sources L1, L2, L3... light on the many elements e11-12, e12-13, e13-14, e14-15, e15-16, e16-17 in many operational areas 5, 8.

As may be clear to a person skilled in the art, the invention is not limited to the elements 10 and/or the holders 11 and/or 10 sources of light in the form of multiple sources L1-L3, light, etc., shown on the schematic drawings.

Fig. 3a schematically shows the electrical circuit in accordance with an embodiment of the invention. Fig. 3a shows the source 30 of the power supply, the actuator 40 and the source 20 of the light, and optional managed device 41. The actuator 40 and the source 20 of light connected in series to form on�sledovatelei layout. Incremental linking is electrically connected via terminals 50 of the power source 30 of the power supply. The source 30 of the power supply provides while using the electrical power signal. In this embodiment, the implementation of the source 30 of the power supply is a current source, arranged with the possibility of providing current in a consistent layout. The current can be controlled depending on the required orientation and light intensity of the light beam. Thus, the actuator 40 and the source 20 of light serves the same current, which determines how the orientation of the light beam (since the current actuates the actuator 40) and the light intensity of the light beam (since the current source excites the 20 light). The current may be, for example, a constant current with a current level that is amplitude-modulated in which, for example, the light intensity is essentially proportional to the current level, and orientation, for example, is essentially proportional to the content of the power supply, which may be proportional to the square of the current level. Current, alternatively, can represent, for example, the current pulse width modulation with a fixed level of current and modulated with a pulse width of, for example, the light intensity is essentially proportional to Chi�ine pulse, and orientation, for example, essentially proportional to the concentration of power in the current, which in this case can be proportional to the square of the pulse width. Orientation, therefore, has a predetermined relationship with the light intensity, in which the predetermined relationship is determined from the relationship between orientation and current and between light intensity and current.

Predetermined relationship may be a fixed relationship. A predetermined relationship, in the alternative, for example, may be selected by the user or by the controller from a plurality of different predetermined relationships (which can also be called as presets). The lighting unit 1 therefore, optionally, may contain controlled device 41 to provide that a plurality of different pre-determined relationships, wherein the control device 41 is electrically linked to the actuator 40 with the possibility of adaptation of the current through the actuator 40, such as a controllable resistor 41, is arranged parallel to the actuator 40, as shown in Fig. 3a. Each predetermined relationship of the plurality of different predetermined relationships may correspond to the corresponding value of the managed device 41, for example, sootvetstvuyushchuyu resistor; the current is then distributed accordingly between the path through the actuator 40 and a controllable resistor 41, defining, thus, the relationship between the current through the actuator 40 and the (total) current through the source 20 of light. In an alternate embodiment of the controlled device 41 or replace it further comprises a nonlinear element such as a Zener diode with a certain voltage of the Zener diode. The use of this Zener diode may, for example, it is preferable to determine the predetermined relationship with the effect that for large electrical power signal corresponding to a voltage higher than the Zener voltage, which is higher than the Zener voltage, the orientation of the light beam may remain essentially constant, while the light intensity can be increased by further increasing the signal electric power: a predetermined relationship, therefore, can be essentially proportional relationships below the level of the electrical signal power associated with the voltage of the Zener diode (which may be referred to as threshold level), whereas, a predetermined relationship is essentially flat (i.e. orientation essentially constant with further increase in light intensity), the above-mentioned Pirogovo� level.

In this and the following examples, the source 20 of the light is represented as a serial connection of four light emitting diodes (LED), but the source 20 of the light, in the alternative, may contain different types of light sources and/or multiple light sources and/or another electrical arrangement of a plurality of light sources. The source 20 of the light may, for example, correspond to the first set of LED connected in series, forming a first serial Podkopaeva, the corresponding second set of LED's connected in series, forming a second consecutive Podkopaeva, and the first and second serial Podkopaeva are connected in parallel to form source 20 light.

Fig. 3b schematically shows the electrical circuit in accordance with an embodiment of the invention. Fig. 3b shows the source 30 of the power supply, the actuator 40 and the source 20 of the light, and optional managed device 41. The actuator 40 and the source 20 of the light are connected in parallel to form a parallel link. Parallel arrangement electrically connected through the connectors 50 of the power source 30 of the power supply. The source 30 of the power supply provides while using the electrical power signal. In this embodiment, the implementation of the source 30 of the electric power�I represents the source voltage, linked with the ability to provide voltage in a parallel arrangement. Voltage can be controlled depending on the required orientation and light intensity of the light beam. Thus, the actuator 40 and the source 20 of the light provided by the same voltage that determines how the orientation of the light beam (as the voltage that actuates the actuator 40) and the light intensity of the light beam (as the voltage that energizes the light source of 20).

Predetermined relationship may be a fixed relationship. A predetermined relationship, in the alternative, for example, may be selected by the user or by the controller from a plurality of different predetermined relationships (which can also be called as presets). The lighting unit 1 can therefore optionally contain controlled device 41 to provide so many different pre-determined relationships, wherein the control device is electrically linked to the actuator 40 to adjust the current through the actuator 40, such as a controllable resistor 41, is arranged in series with the actuator 40, as shown in Fig. 3b, wherein a serial arrangement of the actuator 40 and the controlled resistor 41 is arranged in parallel with the light source. Each pre-determined�I relationship from a plurality of different predetermined relationships may correspond to the corresponding value of the managed device 41, for example, the appropriate value of the resistor; the voltage then distribute accordingly the actuator 40 and controlled resistor 41, defining, thus, the relationship between the voltage across the actuator 40 and the (total) voltage source 20 light.

Fig. 4 shows the electrical circuit in accordance with an embodiment of the invention. Fig. 4 shows the source 30 of the power supply, the actuator 40 and the source 20 of light. The actuator 40 and the source 20 of light connected in series, forming a serial arrangement. Incremental linking is electrically connected via terminals 50 of the power source 30 of the power supply. The source 30 of the power supply provides while using the electrical power signal. In this embodiment, the implementation of the source 30 of the power supply is a switched voltage source, arranged with the possibility of supplying voltage to incremental linking. Voltage can be controlled depending on the required orientation and light intensity of the light beam. The actuator 40 and the source 20 of light together form the load for the source of electrical power, which can be parametrisation on its impedance. Thus, a consistent layout serves a current with a current level corresponding to the supply voltage and the imp�ANSA. This current, therefore, serves in a sequential arrangement of the actuator 40 and the source 20 of light. Thus, the actuator 40 and the source 20 of light provide the same current, which determines how the orientation of the light beam (since the current actuates the actuator 40) and the light intensity of the light beam (since the current source excites the 20 light). Current can, for example, a constant current with a current level that is amplitude-modulated, which is obtained by amplitude modulation of the voltage fed power source 30, and in which, for example, the light intensity is essentially proportional to the current level, and orientation, for example, is essentially proportional to the content of the power supply, which may be proportional to the square of the current level. Current, alternatively, may be a current, for example, pulse width modulation with a fixed level of current and a modulated pulse width, in which, for example, the light intensity is essentially proportional to pulse width, and orientation, for example, is essentially proportional to the content of the power supply, which may in this case be proportional to the square of the pulse width. As shown in Fig. 4, the current pulse width modulation may be, for example, installed in the power source 30 through re�connections between the low voltage Vlow, preferably equal to the voltage of the earth (or non-zero reference voltage, to determine the offset voltage and current), and high level Vhigh voltage using pulse-width controller CON, to control the first switch 52 connected between the output node 51 and the first source node, due to the high level Vhigh voltage and the second switch 53 connected between the output node 51 and the second source node, due to the low level voltage Vlow.

Fig. 5 shows an exemplary embodiment of the lighting unit 1 in accordance with the invention. The lighting unit 1 comprises a single carrier 10, a source 20 of light containing four LEDs. The carrier 10 is suspended on the ceiling, using two holders 11, individually denoted as s11 and s12, and also called pendants 11. Thus, the carrier 10 is suspended from the ceiling by means of a first suspension s11 and the second suspension s12, the second suspension s12 is provided to the actuator 40.

In this example, the actuator 40 includes a bimetallic spring, which is connected to its freely moving end 41a of the carrier 10 through the first part 11a suspension second suspension and is connected through its other end 41b through with the ceiling portion 11b suspension second suspension. Detailed description of embodiments of the actuator, soteriades� bimetallic spring, will be described below with reference to Fig. 11a-11b and Fig. 12a-121.

The power source 30 is connected via terminals 50 power (shown schematically) with actuator 40 and the source 20 of light in accordance with, for example, one of the variants of the implementation described above with reference to Fig. 3a, Fig. 3b or Fig. 4. As an example, the power source is a current source according to Fig. 3a, is arranged for supplying current to the sequential arrangement of the light source of 20 and actuator 40. As you change the current also changes the light intensity of the light beam generated by the source 20 of light. In addition, as the variation of the current, the actuator 40 will lower or raise the carrier 10 with the second suspension s12. For example, when the actuator 40 includes a bimetallic spring, the change in current leads to a change in power dissipation in a bimetallic spring 41, and thus the temperature, which causes the bimetallic spring raises or lowers its free-moving end. The operation of the bimetallic spring will be described in more detail below. The power pins can be as simple as a plug.

An illumination unit 1 shown in Fig. 5 may, for example, be used to illuminate the object on the wall at the top. The object may, for example, be a picture in the exhibition space in the Museum. Codepostal missing in the exhibition space, the lighting unit 1 can provide a low level of General lighting of the exhibition space, lighting, essentially vertically downward from the ceiling. The picture is thus illuminated by the light of reduced intensity, since the intensity of light is low, and the light beam is not pointed at the picture. However, when a visitor is in the exhibition space, which presents a picture, the light intensity increases, and the orientation of the light beam is directed to a picture so that the visitor can see the picture under appropriate lighting conditions.

It should be understood that the array of lighting units 1 in accordance with Fig. 5 can be used, for example, positioned on the same line to ensure the line of light which can be adjusted by light intensity and orientation.

Fig. 6 shows another exemplary variant of implementation of the lighting unit 1 in accordance with the invention. The lighting unit 1 comprises a set of supports 10, in this case it's two, which are designated as the left media 10L and the right media 10R, each of which contains a suitable source 20 of the light (indicated by, respectively, 20L and 20R), containing four LEDs, arranged with the possibility of reception of the electric power supply (see Fig. 7a and 7b). Two carrier 10 is suspended on�the ALC, using three of the holder 11, separately denoted as s11, s12 and s13. In particular, the left-hand carrier 10 is suspended from the ceiling using a first suspension s11 and the second suspension s12, the second suspension s12 is provided by the actuator 40 is arranged with the possibility of reception of the electric power supply (see Fig. 7a and 7b). The right carrier 10 is suspended from the ceiling by a third s13 suspension and the second suspension s12. The actuator 40, secured second suspension s12, therefore, arranged with the possibility to influence both the media 10.

During use, the power source 30 is connected via terminals 50 power (shown schematically) to the actuator 40, the source of light 20L, secured to the left carrier 10L, and a source 20R light, secured on the right media 10R. The power pins are arranged with the possibility of signal flow of electrical power to the actuator 40, the source 20L light source and 20R light, for example, in accordance with the variants of implementation, described below (Fig. 7a and 7b), with the possibility of generating rays of light oriented in accordance with a predetermined relationship to the intensity of the light beam, as will be described in detail with reference to Fig. 8a and 8b.

In the first variant of implementation, shown in Fig. 7a, the actuator 40, the source 20L light source and 20R of the world is connected in series to form a serial component�VKI, and this serial arrangement is connected during use with the power source 30. The actuator 40, the source 20L light source and 20R light, thus, all take the same current. The result is a predetermined relationship between the intensity of light rays (a certain current through sources 20L, 20R of light) and the orientation of the respective light rays (defined (the same), the current through the actuator 40).

In the second variant of implementation, shown in Fig. 7b, the source 20L light source and 20R light connected in parallel with the serial arrangement of the actuator 40 and the power source 30. In the example shown in Fig. 7b, the source 20L light source and 20R light, therefore, take the same current, which is equal to half the current taken by the actuator 40. The result is a predetermined relationship between the intensity of light rays (determined by the current through the source 20L, 20R of light) and the orientation of the respective light rays (defined (double) the current through the actuator 40).

Fig. 8a and Fig. 8b illustrates the use of the lighting unit 1 according to any one of the embodiments of Fig. 6, Fig. 7a and Fig. 7b. Fig. 8a shows the carrier 10 with the orientation corresponding to, for example, General lighting, i.e. with a flat profile light with moderate brightness, to�the EO actuator 40 acts on the carriers 10 thus, the media 10 is essentially aligned in the plane. Fig. 8b shows the carriers 10 with the orientation corresponding to the focused lighting, such as task lighting, that is, with concentrated profile lighting with greater brightness, the actuator 40 acts on the carriers 10 so that the carriers 10 are at some angle relative to each other.

In embodiments of Fig. 6, Fig. 7a, Fig. 7b, Fig. 8a and Fig. 8b receive a predetermined relationship between the intensity of the rays of light and orientation, in particular the degree of concentration of the rays of light.

Fig. 9a and Fig. 9b illustrates an alternative implementation in which a single carrier 10 is suspended from the ceiling using a passive suspension at its end, and a Central suspension provided by an actuator 40. In this alternative embodiment of the single carrier 10 has a flexible surface, and the holders 11 preferably are rigid holders that hold and pull the flexible surface. Fig. 9a illustrates that such a flexible surface can be provided as a flat surface to ensure uniform illumination, for example, as a General lighting, for example, when the current level is moderate, and thus, the light level is low, and defocused orientation� and distributed. Fig. 9b presents that such a flexible surface can be generated when you change the current, and the intensity and orientation are adjusted accordingly.

Fig. 10a and Fig. 10b shows another exemplary variant of implementation of the lighting unit 1 in accordance with the invention. The lighting unit 1 comprises a set of supports 10, in this case two are shown as the left media 10L and the right media 10R, each of which contains a suitable source 20 of the light (indicated respectively as 20L and 20R), containing four LEDs. Two carrier 10 is suspended from the ceiling using three holder 11, individually denoted as s11, s12 and s13. Two carrier 10 is arranged with the possibility of orientation by using two actuators 40, individually designated as 40L and 40R. In particular, the left-hand carrier 10 is suspended from the ceiling by means of a first suspension s11 and the second suspension s12, the first suspension s11 provided by the actuator 40L. The right carrier 10 is suspended from the ceiling by means of a second suspension s12 and the third suspension s13, wherein the third pendant s13 provided with actuator 40R. The second suspension s12, thus, is used for suspension in the center of both speakers 10L and 10R, and each carrier 10L, 10R can be individually focused using their respective actuators 40L, 40R. The actuator 40L and source 20L with�ETA electrically connected, for example, in series with one another. The actuator 40R and source 20R light electrically connected, for example, in series with one another, but are electrically isolated from the actuator 40L and source 20R light. While using the first signal power fed into the actuator 40L and the source of light 20L, secured to the left carrier 10L, and the second signal power fed into the actuator 40R and source 20R light provided on the right media 10R.

Fig. 11a and Fig. 11b shows the approximate variant of implementation of the actuator 40 for use in the lighting unit 1 in accordance with the invention. In this embodiment of the actuator 40 includes a bimetallic spring, which is connected with its freely movable end 41a of the carrier 10 through the first part 11a suspension suspension of relevant and connected through its other end 41b through with the ceiling portion 11b of the suspension from the suspension.

The actuator 40 is arranged with the possibility of connection with the power source 30, for example as described in one of the embodiments presented above. As an example, the power source may provide a current source according to Fig. 3a, is arranged with the possibility of supplying current in a serial arrangement of the light source of 20 and actuator 40. Since the current is changed, for example, increases from the first level I0 current to a higher level current I1, then change the power scattered�I'm in a bimetallic spring 41, and, thus, its temperature, which has a different effect on the length of the different layers of a bimetallic spring, encourages the bimetal spring to change its shape and the lifting or lowering of its freely movable end, respectively, as indicated by Δ in Fig. 11b.

Fig. 12a-121 illustrate possible embodiments of a bimetallic spring 41. Fig. 12a-12l illustrate variants of implementation, in which the bimetallic spring 41 contains a stack of at least two layers of different conductive materials: the first layer 42 and second layer 43. The first layer 42 may be, for example, the first metal layer, for example a tungsten layer, and the second layer 43 may be, for example, the second metal layer, for example a copper layer, wherein the second layer has a greater coefficient of thermal expansion than the first layer so that the first and second layers will have different length change, when you change their temperature. As a result, the bimetallic spring changes its form, and its free end is moved accordingly.

Fig. 12a illustrates a bimetallic spring 41 in accordance with the first embodiment of implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42 and second layer 43, arranged in layers each other. Multi-layered structure 41 e�ctricas connected to the signal supply source, with the help of the equivalent circuit, such as a parallel arrangement of a first resistor corresponding to the first layer 42, and a second resistor corresponding to the second layer 43, as shown in Fig. 12b. When current I flows through these layers, the power dissipated due to the resistance of the layers. It is believed that the scattering power is first order (unlike, for example, from the influence of temperature on the resistance of the respective layers) is proportional to the square of the current level (or the average value when the current pulse): thus, the bimetallic spring 41 receives the temperature depending on the current I.

Fig. 12c shows a bimetallic spring 41 in accordance with the second variant of implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42, intermediate layer 44 and second layer 43. The intermediate layer 44 preferably is an electrically insulating layer. An implementation option, therefore, differs from that shown in Fig. 12a, intermediate electrically insulating layer 44 is provided between the first layer 42 and second layer 43. Multi-layered structure 41 is again electrically connected to the signal power source, such as current I, with the help of the equivalent circuit, such as a parallel arrangement of a first resistor, confor�embracing the first layer 42, and a second resistor corresponding to the second layer 43, as shown in Fig. 12d. In an alternative embodiment of the intermediate layer 44 is a deformable layer is designed so that it absorbs the mechanical stress between the first layer 42 and second layer 43 during expansion, and thus prevents damage to the multilayer structure, for example, as a result of stratification.

Fig. 12e illustrates a bimetallic spring 41 in accordance with the third variant of implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42, an intermediate insulating layer 44 and second layer 43. The first layer 42 and second layer 43 is arranged with the possibility of electrical connection with a source 20 of light in a series connection, as indicated in Fig. 12f. While using the current path continues through the first layer 42, the source 20 of light and the second layer 43, which is marked with the current I in Fig. 12e in Fig. 12f. Thus, the first layer 42 and second layer 43 is experiencing the same current I, and this current is not divided by the first layer 42 and second layer 43, as in Fig. 12a and Fig. 12b; the current through each of the first and second layer, thus, compared with the situation shown in Fig. 12a and Fig. 12c. This may preferably lead to a more efficient heating bimetallicheskie.

Fig. 12g illustrates a bimetallic spring 41 in accordance with the fourth variant implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42, a heating layer 48 and the second layer 43. In this embodiment of the heating layer 48 preferably has a lower resistance than the first and second layers so that a current I, in essence, flows entirely through the heating layer 48, and only a small part of the current, in any case, flows through the first and second layers. The heating layer 48 is in thermal communication with the first layer 42 and second layer 43 and serves to heat the first layer 42 and second layer 43, when the heating layer 48 a signal of electrical power. Multi-layered structure 41, thus, may be electrically connected to the signal power source for receiving the current I and the equivalent circuit of, for example, may correspond to the resistor corresponding to the heating layer 48, as shown in Fig. 12h. In a preferred embodiment of the first layer 42 and second layer 43 are non-conductive or at least poorly conductive, and are selected, for example, due to significant differences in coefficient of thermal expansion. In particular, it may be preferable to select one of first and second layer so as to have about�relatively large coefficient of thermal expansion, which leads to a significant displacement with low current and low heat dissipation.

Fig. 12i illustrates a bimetallic spring 41 according to the fifth variant implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42, the first intermediate insulating layer 44, the heating layer 48, the second intermediate insulating layer 44 and second layer 43. The first and second intermediate insulating layers 44 are used for electrical insulation of the heating layer 48 of the first layer 42 and second layer 43, thereby allowing the use of conductive materials in the first and/or second layers, thereby substantially separating the electrical behavior (defined largely by the heating layer) of the mechanical behavior (defined largely by the behavior of thermal expansion of the first layer 42 and second layer 43). As in Fig. 12g, the heating layer 48 is in thermal communication with the first layer 42 and second layer 43 and serves to heat the first layer 42 and second layer 43, when the heating layer 48 a signal of electrical power. And again, the multi-layer structure 41 may be electrically connected to the signal power source for receiving the current I by using the equivalent circuit, it is suitable� resistor, which corresponds to the heating layer 48, as shown in Fig. 12i.

Fig. 12k illustrates a bimetallic spring 41 in accordance with the sixth variant implementation. The bimetal spring 41 contains a multi-layered structure of first layer 42 and second layer 43, with conductive heater 48 that is wound around a multi-layer structure. An intermediate insulating layer (not shown) may be provided between the wire heater and a multi-layered structure to prevent electrical contact. Wired the heater 48 may be, for example, Konstantinovy wire, preferably making possible thermal dependence of the resistance of the bimetallic spring 41 and, thus, the actuator 40. Wired the heater 48 is in thermal communication with the first layer 42 and second layer 43 and serves to heat the first layer 42 and second layer 43, when wired to the heater 48 signal electric power. And again multi-layered structure 41 may be electrically connected to the signal power source for receiving the current I by using the equivalent circuit corresponding to the resistor that corresponds to a wired heater 48, as shown in Fig. 12l.

Fig. 13a and Fig. 13b shows an alternative exemplary variant of implementation of the actuator 40 for use in the lighting unit 1 is in accordance�accordance with the invention. In this embodiment of the actuator 40 includes an Electromechanical solenoid 45, which contains the core 46 within the electromagnetic inductive coil 47. The core 46 is connected to the carrier 10 via a suspension 11a and the coil 47 is secured to the ceiling using the suspension 11b. The core 46 during use is in electromagnetic communication with the coil 47. Thus, when the current through the coil 47 is changed, the core 46 will move relative to the coil 47 and affect the carrier 10 to guide the light beam generated by the light source of 20 on the carrier 10. For example, when the current changes from the first level I0 current to a high level of current I1, the core 46 can move up with the offset Δ, as indicated in Fig. 13b. The solenoid 45, at least during use is connected to a power source 30 and a source 20 of light and is built with the same signal power (e.g., current), and the source 20 of light. The orientation and intensity of light of the light beam, thus, related to each other in accordance with a predetermined relationship defined by the behavior of the movement of the core, as a result of the signal power source (e.g., current) and the corresponding behavior of the light intensity, as a result of the signal power source (e.g., current).

As an example, can be used�to isolates commercially available solenoid, containing the plunger, the coil and the frame. Typically, such a solenoid can be available with different coil parameters. A common feature of amps are the coils, i.e. the product of the current flowing through the coil, and the number of turns. Lower inrush current can be achieved by selecting the coil with lots of turns, while in the system with identical high current power will be generated by a high current which is supplied to the coil with fewer turns. Because the lighting system will be used for long periods of time, the solenoid is preferably chosen in accordance with its rating at 100% duty cycle, while during short periods of high intensity brightness (for example, to transmit a signal about a special situation for a limited period of time) are allowed to use large currents, which also leads to large forces.

As a practical example: a solenoid having dimensions of 50 mm x 38 mm x 30 mm and the diameter of the plunger 15 mm, allows you to generate force up to 50 N and may have a stroke of up to 25 mm during operation in steady state. Given the relatively small weight, for example, LEDs and the possible use of restraint design with low weight, such a large force could afford to host with�of glenoid elsewhere in the media than at the end, to get more offset.

In an alternative embodiment of the coil 47 is connected to the carrier 10 via a suspension, the core 46 is fixed on the ceiling, and the change in current through the coil 47 causes movement of the coil 47, and, thus, the change in the orientation of the United media 10.

It should be understood that without deviating from the invention other variants of implementation can also be considered by the person skilled in the technical field in which the Electromechanical solenoid 45 has a different physical layout.

Fig. 14 shows the space 1000, containing the lighting system 100 in accordance with the invention. The lighting system 100, as an example, fixed to the ceiling 1002 in space. Table 2 chair and 4 are located in space. The provisions of table 2 and the chair 4 can be changed. In addition, the number of tables and chairs can be changed, for example, to accommodate visitors when the space is a living room, or for placement of additional jobs when the space is an office space.

The lighting system 100 may be further connected to the controller 1004, which may be arranged outside relative to the lighting system 100, for example, in the ceiling 1002, but which can also be integrated in the lighting system 10. The controller 1004, in particular, linked with the ability to control the lighting system 100, and more specifically, the intensity and orientation of light rays of different lighting units 1 of the lighting system 100.

In addition, the intensity and orientation of a plurality of light rays forming the profile of the illumination generated by the lighting system 100 may depend on the sensor signal from the sensor 1006 (such as proximity sensor, fire detector, smoke sensor, temperature sensor, etc.), wherein the sensor is arranged with the possibility to perceive the object or in the area that can be illuminated by the lighting system 100, or may be a symptom selected from the group consisting of smoke and heat, and thus the controller 1004 is arranged to control the intensity and orientation of each of the light beams for forming the profile of the illumination generated by the lighting system 100, depending on the sensor signal. Therefore, in still another embodiment of the lighting system further comprises a sensor such as a proximity sensor or a smoke sensor, or temperature sensor, etc., which can be arranged outside relative to the lighting system 100, but which can also be integrated in the lighting system 100. The term "sensor" may also refer to the plurality of sensors. Such sensors may, for example�, to be linked with the ability to perceive the same parameter (e.g., the touch of the user) in different places, or with the possibility of sensing different parameters (such as input from a user and smoke, respectively).

In the drawings less important elements such as electric cables, etc., were not drawn (in General) for the clarity of presentation.

In this description, the term "substantially", such as, for example, "substantially flat" or "substantially consists", etc., will be clear to a person skilled in the art. In embodiments, the feature "substantially" can be removed. In appropriate cases, the term "substantially" may also include variants of the implementation of "fully", "completely", "all", etc. where applicable, the term "substantially" may also relate to 90% or more, for example 95% or more, particularly 99% or more, including 100%. The term "contains" also includes variants of implementation, in which the term "includes" means "consists of".

In addition, the terms "first, second, third" etc. in the description and in the claims are used to distinguish between similar elements and not necessarily for describing a sequential or chronological order. It should be understood that the terms used so interchangeably�and, in appropriate circumstances, and that embodiments of the invention described herein is arranged with possibility of operation in other sequences than described or shown here.

In the claims, any reference sign position, placed between parentheses shall not be construed as limiting the claims.

The term "and/or" includes any and all combinations of one or more of the associate is presented in the form of a list of items. Use of an element in the singular does not exclude many. The invention can be embodied by the hardware that contains several distinct elements, and by using appropriate �the Braz programmed computer.

SUBSTANCE: by means of personal computer, using specialized graphic software, a frame of required light diode illumination is formed. By means of color pattern, each imitator of light diode module is colored. After forming of one frame, other frames are formed, which require to be colored in similar way. Number of frames is determined by given model of illumination. As a result, animated cinematic is produced, which reflects appearance of illumination model. After that, programmed model is transferred to flash memory of controller through RS-485 interface port. Then, controller outputs aforementioned data into loop line with light diode modules.

EFFECT: using device for decorative or primary lighting of architectural objects makes possible fast generation of complicated and various models and types of illumination and backlight, with possible control over each module.

FIELD: technology for providing power to auxiliary devices of a light.

SUBSTANCE: power of one or several auxiliary devices 26 of light is extracted from lamp power impulse series, fed by phase light controller 28. Direct current power block 44 is connected to output 38,40 of light controller 28 to produce and store direct current energy for powering auxiliary devices. Controller 48 of lamp is connected to output 38,40 of light controller 28 to transfer power of power impulses to lamp 24. Lamp controller 48 has adjustable impulse transfer characteristic for powering the lamp not to interfere with its operation due to alterations to power consumed by auxiliary devices. Adjustable impulse transfer characteristic may be provided with switching device 76, which either interrupts or blocks selected parts of lamp power impulses. Adjustable impulse transfer characteristic maintains constant apparent brightness of lamp, independently on changes of power consumption by auxiliary devices. In disabled state or in preliminary heating mode transfer of power to lamp 24 is decreased to avoid emission of visible light. In full brightness mode lamp power impulses are practically left unchanged by lamp controller 48.

EFFECT: provision of power to auxiliary devices without using auxiliary force cables and without interfering with operation of light.
