The technical field

The present invention relates to a lighting device containing the light sources and svetosobirayushchim means, accommodated in the housing. Svetosobirayushchim means collect light from at least one light source and convert the collected light into rays of light sources coming from the specified case.

The level of technology

Create various lighting effects fixtures are increasingly used in the entertainment industry to create different lighting effects and mood lighting to show live television performances, sporting events or as part of architectural installations.

Used in the entertainment industry luminaries typically generate a light beam having a certain width and divergence, and can, for example, be lamps flood light, creating a relatively wide light beam with a uniform distribution of light, or lamps with non-uniform distribution, is configured to project an image on the target surface. There is a tendency of the increasing use of this type of lamps in each show and each installation and, as a result, the lamps become more visible to television viewers or sectors. Lamps usually create a luminous effect sanctorum away from me, and thus the appearance of the lamp is not so interesting and aesthetic. Manufacturers of lamps try, as a consequence, to produce lamps aesthetic designs with a more attractive appearance. However, it is very difficult, because the design of the lamp body usually depends on the physical requirements, certain technical details of the lamp, such as optics, mechanics, electronics, cooling and so on

Used as a light source of the led component has changed the appearance of the majority of lights with multiple LEDs, replacing a single light source. This applies to all types of lighting, that is, to the General, home, industrial, entertainment and so on, the Most notable change here is that all of the multiple light sources are now visible to the viewer and the light comes with a larger area. Now, when the majority of led lamps is visible LEDs, some consumers don't like the look of many light points. Instead, you want more homogenous, smooth light emitted to avoid cheap-looking "fair" form with a very large number of light sources. Point "fair" view of the lamps, mixing colors to the exit of the light from the housing, and for fixtures where the colors are mixed in the air or on the wall.

Detailed description of the invention

The present invention is described on the example of the lamp with movable head containing several LEDs forming the light beam, however, the specialist in the art understands that the present invention relates to a lighting device using any type of light source, for example, discharge lamps, OLEDs, plasma sources, halogen sources, fluorescent lamps, etc. and/or combinations thereof. It should be borne in mind that examples of the invention are simplified and explain the principles of the present invention, not its specific examples of implementation. Specialist, it is thus clear that the present invention can be implemented in many different ways, and may also contain additional components in addition to these components.

In Fig.1A-1b shows the known lighting device, and Fig.1A is an axonometric projection, and Fig.1b exploded view. The lighting device is a lamp 101 with movable head containing the base 103, the bracket 105 that is attached to the base can be rotated, and the head 107 attached to the bracket can be rotated.

In the shown example, the implementation of this and the finding of the head contains multiple light sources and multiple light-harvesting means 109 for collecting light, located in the housing 111 of the head. Svetosobirayushchim means collect light from the light source and convert the collected light into light rays 113 from the light sources (shown only one beam) emerging from the shell.

In the example implementation of the present invention, the housing 107 of the head has a body 111 of the head, made in the form of "cups", which are placed one above the other display 115 (visible from the back of the head), the main circuit Board 117, fan 119, the heat sink 121, PCB 123 LEDs and a host of lenses. Printed circuit Board 123 of LEDs includes LEDs 124, and a host of lenses contains the holder 125 lenses and the kit lens, which constitute the light-harvesting means 109 for collecting light. Each of the light-harvesting tool is configured to collect light from each led and converting the collected light into light rays 113 light sources. The head is attached to the bracket can be rotated by means of two bearings fitted 127, which supports the bracket 105. Rotary motor 129 is configured to rotate the head through swivel belt 131 that is attached to one of the bearings 127. The bracket includes two interconnected parts 132 shell bracket mounted on the frame 134 of the bracket on which races orogeny mounted bearings, rotary engine, the engine pan and bearing pan. PCB 123 contains LEDs light emitting diodes and together with the light-harvesting means 109 in the kit lens forms the light rays of the light sources. The main circuit Board contains the control circuits and drive circuits (not shown), configured to control the LEDs and is known for lighting devices. In addition, the main circuit Board contains switches (not shown) passing through holes in the housing 111 of the head. These switches and display work as a user interface, allowing the user to have a relationship with a lamp with a floating head.

The bracket attached to the bearing 133 pan connected to rotate with the base 103. Engine 135 pan made with the possibility of rotation of the bracket by means of a belt 137 pan connected to the bearing 133 pan. The base plate contains 5-pin male connector 139 and the female connector 141 XLR-type connectors for signal communication Protocol DMX, known in the technical field of lighting design for the entertainment industry, the power input connector 143 and the output power connector 145, circuit Board power source (not shown) and the valve is PR (not shown). A fan blows air into the base through the vents 147.

The specified well-known lighting device uses multiple LEDs to replace a single light source, known until the led component as a widely used light source. However, this lighting device has a different appearance, because the number of light sources is visible to the viewer and the light emerges from a larger area. If the lamps are devices with mixing colors when using single-color LEDs, you can see all the colors of the LEDs. However, some customers don't like the look of many light points. Instead, they require more homogeneous, monotonic output light to avoid cheap-looking "vulgar" form with a very large number of light sources.

The lighting device shown in Fig.1A and 1b, represents only one example of the known lighting devices, and specialist it is clear that there are many different examples of the invention are made by various manufacturers.

In Fig.2A - C shows a simplified example of the implementation of the lighting device 201 according to the present invention. In Fig.2A shows the top view of Fig.2b shows poperechnyy view in section along the line a-a, a in Fig.2C shows a top view without the scattering of the coating.

The lighting device 201 includes the light sources collected in the first group of light sources 203 (indicated by white boxes) and the second group of light sources 205 (indicated by black boxes). Light sources mounted on the printed circuit Board 207, and the two groups of light sources can be controlled individually, for example, by a controller (not shown) known in the field of lighting technology. The controller thus designed to work with these two groups of light sources as two separate light sources that can be managed separately. However, expert it is clear that the lighting device may also be adapted to separate each group of light sources into several subgroups, which can be controlled separately, and that it is also possible to control each single light source separately. Svetosobirayushchim means 209 for collecting light located above the light sources of the first group 203 and around them and to collect light from the first group of light sources and converting the collected light into light rays 211 of the light sources. Svetosobirayushchim means 209 can be done is by any optical component, able to collect light from the light source and to convert the light into light rays, and can, for example, be an optical lens, mixers, lights, lenses of total internal reflection, etc., In the example implementation of the invention svetosobirayushchim means 209 is made in the form of lenses of total internal reflection used in the prior art, and expert it is clear that the lens of total internal reflection can be developed according to their light yield of the light source and described the optical properties of the light beam 211 of the light source. Light rays 211 are combined into one large light beam as the distance from the lighting device.

The lighting device comprises a diffusing coating 213 located above the circuit Board 207, and this scattering coating contains at least one dispersing section 215 and at least one merseyway section 217. The scattering plots 215 receive the light formed by the second group of light sources 203 and diffuse the received light in many directions, shown by arrows 219. The result can be created in a new light effect, because the area between the light beams can have different color emitted by the second group of light sources. This appearance can be dynamic when the first control is Rupay light sources and the second group of light sources individually, what is known in the field of lighting design in the entertainment industry. The second group of light sources can also be made with the possibility of light emission, having essentially the same color as the light emitted from the first group, resulting in a surface lighting device is visible as a single surface with a uniform color. The scattering sites can be located between pressively areas, resulting in avoiding the point of appearance, because the area between pressively areas now have essentially the same color as the light rays 211, emerging from the lighting device through nerasseivayushchee areas.

The second group of light sources can work as background lighting with its own management under the DMX Protocol, and provided the ability to change the color and intensity regardless of the first group of light sources. They may also have the intensity and color associated with the first target color in a predictable way, or to have a separate control to provide contrasting colors or different intensity. This adjustment and/or control of light sources can be performed remotely via a Central control device or in the lamp.

This is an invention may, for example, to use the known lighting device shown in Fig.1A - 1b, through the location of the second group of light sources between the original LEDs 124 in the circuit Board 123 LEDs and scattering of light from these light sources areas 126 of the holder 125 lenses, which are located between the holders 125 lenses.

In Fig.3A and 3b, respectively axonometric projection and a side view of the lighting device shown in Fig.1A - 1b, modified in the lighting device according to the present invention.

In this example implementation, the LEDs 301 (shown as black boxes) installed in the holder 125 lens between the light-harvesting means 109. For example, this can be achieved through the implementation of the lens holder in the form of a printed circuit Board with holes, which can be located svetosobirayushchim means, or by adding the PCB to the original holder of the lenses. The original LEDs 124 (see Fig.1b) and added LEDs 301 is configured to operate as, respectively, of the first group and the second group of light sources that can be managed separately.

In addition, the casing head contains scattering floor 303 (remote from the housing in Fig.3A and installed in Fig.3b), the soda is containing at least one dispersing section 315 and at least one merseyway section 317. The scattering plots 317 receive at least a portion of the light formed by the second group of light sources, and diffuse the received light, as indicated by the arrows 319 (for simplicity they are shown only in Fig.1b). At least part of the light rays 113 of the light sources passes through nerasseivayushchee sections 315 without scattering. It should be noted that, for simplicity, shows only some of the light rays of the light sources. In the point view of the LEDs on the front prevented by the light-scattering cover the emission of light scattering plots and pressively areas, and areas between the lenses, lighted existing internal scattered light from the LEDs dissipate it into the surrounding space.

At least part of the scattering coating 303 protrudes from the housing and, therefore, part of light scattered sideways and backward (as shown by arrows a) relative to the light beams of the light sources. The scattering plots of the scattering of the coating can be lit as from the surface and from the side and thus act as a light guide. As a consequence, provided the opportunity of reviewing the lamp at different angles, and acting scattering coating gives the lamp a new lighting effect.

Nerasseivayushchee areas may be the imp is tive in the form of transparent areas in the form of a flat transparent surfaces, located above the light-harvesting means. Such a flat transparent surface enable light rays from the light sources to pass through without scattering. Although the transparent area can be configured to adjust the divergence of the light beam of the light source facing the light beam will still be well-defined light beam. The scattering of the coating can thus be made in the form of a transparent polymer, where the scattering plots are made by etching the surface of the scattering of the coating. The scattering plot can also be made by coating parts made with the possibility of placing the scattering plot. The scattering surface can also be cast, where tidal completed form with the ability to determine merseyway sections and scattering plots. Nerasseivayushchee plots can also be made in the form of apertures or cut-outs located above mentioned light-harvesting means.

Scattering coating may also contain fastening means enabling the user to attach the scattering floor to the lighting device. Thus, the scattering layer may be a standard feature or optional.

In Fig.4A - 4C shows another diprima implementation of the lighting device according to the present invention, moreover, Fig.4A is an axonometric projection, Fig.4b represents the head disassembled, and Fig.4C is a cross-section of the head. The lighting device is a lamp 401 with movable head containing the base 403, the bracket 405 attached can be rotated to the base, and the cylinder 407 is attached can be rotated to the bracket.

In the example implementation of the present invention, the cylinder 407 includes a front housing 409 and rear casing 411, connected components and the casing head. The following components are located in the housing head:

display 413 (visible from the back of the head)

- fan 415

- the main circuit Board 417

- duct 419

- heat-removing device 421

- printed circuit Board 423 of the first group of LEDs

- the light-harvesting node 425

- 427 engines scaling

- PCB 429 of the second group of LEDs

- scattering coating 431

- zoom 433.

The fan is arranged to blow air from the rear side of the housing through the main circuit Board 413 and the duct 419. The duct is made with the possibility of the direction of the blown air to the Central part of the heat-removing device 421, after which the air leaves the enclosure for the flax direction. Thus, heat can be removed from the printed circuit Board 423 of the first group of LEDs. Printed circuit Board 423 of the first group of LEDs includes LEDs 424 of the first type (shown only in Fig.4C), collected in the first group of LEDs. Light-harvesting node 425 contains svetosobirayushchim means 435, located in the mounting means 437, and each fastening means 437 made with the possibility of placement of each of the light-harvesting tool over one of the LEDs of the first type. In a specific example implementation of the present invention, the LEDs of the first type are the LEDs RGBW type (4 the crystal in 1 led), containing crystals creating red, green, blue and white color, and each of the light-harvesting tool is made with the possibility of collecting and mixing the light from the LEDs of the first type and convert the collected light into a light beam. Light rays 438 (shown only in Fig.4A) are, thus, generated by the LEDs of the first type and light-harvesting devices. Svetosobirayushchim device can, for example, be performed as described in pending patent application DK RA 2010 70580, filed by the same applicant and incorporated here by reference.

PCB 429 LEDs of the second type is located above the circuit Board 423 LEDs of the first type in the bottom portion of the mounting means 437. This PCB LEDs includes LEDs of the second type (not shown) and openings 439, through which can pass svetosobirayushchim means 435 and the upper part of the mounting means 437. In a specific example implementation of the present invention, the LEDs of the second type are the LEDs RGBW type (4 the crystal in 1 led), containing crystals creating red, green, blue and white. Compared to the LEDs of the first type LEDs of the second type consume less power and require, therefore, less cooling. However, expert it is clear that the LEDs of the second type may be identical to the LEDs of the first type.

Scattering cover 431 is located above the PCB 429 LEDs of the second type and contains nerasseivayushchee parts, made in the form of holes 441, which is the upper part of the light-harvesting means 435, and the light rays formed by the LEDs of the first type will, therefore, through the scattering surface without scattering. In contrast, light from the LEDs of the second type falls on the scattering coating 431 and will be scattered, and, as a consequence, the scattering coating 431 looks like a single-lit surface.

The lighting device also includes a zoom 433 attached to the engines 427 scaling group is a rotary rod 443, who can perform a reciprocating movement by means of 427 engines scaling, as shown by the arrow 445. In a specific example implementation of the present invention contains optical zoom lens 447, and each optical lens 447 is made with the possibility of changing the divergence of the light rays emerging from the light-harvesting tools. Because of this provided the possibility of changing the divergence of the light rays by moving the zoom back and forth. Zoom is made in the form of one of a transparent solid body, for example, from a polymer or plastic, and look like a uniform illuminated surface, when the ambient light passes through the zoom. The area between the optical lenses 447 contain slanted surface 449 preventing the reflection of light from the surrounding space in the same direction, which makes the appearance of the lighting device more attractive. It should be borne in mind that the zoom can be done in many different ways, for example, in the form of a single, shared optical lens. In addition, it should be borne in mind that the zoom can also be made in the form of the scattering coating, where the field 449 between the optical lenses 447 can be made with the possibility of receiving and scattering of light formed by the light of the new sources of the second type. As a consequence, in this example implementation of the present invention can be scattering the floor 431.

The bracket and the base can be performed by known methods, for example, as shown in Fig.1A - 1b. However, the expert is able to perform these pieces in many different ways.

In Fig.5 shows a block diagram of the lighting device according to the present invention. The lighting device comprises a control unit 501, containing a processor 503, and a storage device 505. The first group 507 light sources and the second group 509 of light sources attached to the control unit 501 and are in accordance with the present invention. The processor acts as the control means and arranged to control the first group 507 light sources and the second group of light sources individually. That is, the control means may control one of the groups of light sources, not driving another group of light sources. The specified control means may, for example, to control the color and/or intensity of light sources and can be based on any type of communication signals, known in the field of lighting technology, for example, pulse-modulated signals, amplitude-modulated signals, frequency modulated signals, wochnik signals, etc. The first group 507 and the second group 509 light sources can thus be controlled separately and independently from each other, and they should be treated as two separate and independent of the group of light sources. It should be borne in mind that it is possible to control the individual light sources of each group by the same control signal, that is, for each light source serves individual control signal, and/or light sources of the group can be divided into subgroups, each of which receives the same control signal.

In one example implementation of the present invention the control means is arranged to control the specified first group of light sources on the basis of the input signal 511, which determines the first target color specified first group of light sources. The input signal 511 may be any signal that can satisfy the communication parameters, and can be, for example, based on one of the following protocols: USITT DMX 512, USITT DMX 512 1990, USITT DMX 512-A, DMX-512-A, including RDM discussed in ANSI E1.11 and ANSI E1.20, or wireless DMX Protocol. ACN stands for "Architecture for control networks; ANSI E1.17 - 2006).

The input signal may, for example, to determine the first target color in the form of any is producing defines the color of the light, which should form the first group of light sources, for example, RGB values of the color coordinates on the chromaticity diagram, and so on, the Control means may be configured to control the second group of light sources based on an input signal, determining a first target color, whereby the second group of light sources can be performed with the possibility of formation of essentially the same color, which was formed the first group of light sources. However, it is also possible to combine the color scheme so that the color of the second set was adjusted so that the color of the second group of light sources differed, but was aesthetically coordinated with each other according to a predefined color scheme. The input signal may also define a second target color and the color of the second group of light sources can be controlled on the basis of the setting of the second target color.

Expert it is clear that the lighting device may also contain additional group of light sources that can be used to create different effects, for example, the third group 511 of light sources that can be managed in the same way that used for the other two groups of light sources.

The second and the third is the group of light sources may operate as a background light with a private management communication Protocol DMX, the color and intensity can be changed independently from the first group of light sources. They can also be pre-defined way to relate intensity and color with the main color of the led or to have a separate control for the production of contrasting colors or different intensity. This adjustment and/or control of light sources can be performed remotely via a Central control unit or on the lamp directly. As a result of this can be created in a new light effect, because the area between the light beams can have different color emitted by the second group of light sources. Such appearance may be dynamic, subject to independent control of the first group of light sources and the second group of light sources, as is well known in the field of lighting design in the entertainment industry.

It should be noted that:
