The technical field

The 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 light beams from the light sources. Light beams from the light sources are emitted from the body.

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 objects.

Used in the entertainment industry luminaries usually create 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 lights with inhomogeneous distribution designed 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 the lamps become more visible to television viewers or sectors. Lamps usually create the t effect light at some distance from himself, 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 defined by the technical characteristics of the lamp, such as the characteristics of its optical parts, mechanical parts, electronic parts, cooling system 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 - General, home, industrial, entertainment and so on, the Most notable change is that all light sources are open to the viewer and the light emitted from 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" with an excessive number of light sources. Point "fair" view of the lamps, smesi the affected color to light radiation from the housing, and for fixtures where the color is mixed in the air or on the wall.

Detailed description of the invention

The present invention is described in relation lamp with movable upper part, containing several LEDs forming the light beam, however, to a person skilled in the art it is obvious that the present invention relates to lighting devices using any type of light source, such as gas-discharge lamps, OLEDs, plasma sources, halogen sources, fluorescent lamps, etc. and/or combinations thereof. It should be noted that the embodiments shown of the present invention is simplified and explain the principles of the present invention, not specific implementations. Specialist, it is thus clear that the present invention can be implemented in many different ways, and may contain additional components in addition to these components.

In Fig.1A-1b shows the known lighting device, where Fig.1A is a perspective view, and Fig.1b - exploded view. The lighting device is a lamp 101 with a movable upper part, containing the base 103, the bracket 105 that is attached to the base with possibly the envy of rotation, and the upper part 107 that is attached to the bracket can be rotated.

In the illustrated implementation of the present invention the upper part contains the light sources and svetosobirayushchim means 109, located in the housing 111 of the upper part. Svetosobirayushchim means collect light from the light source and convert the collected light into light beams 113 from the light source (shown only one beam) emerging from the shell.

In the illustrated implementation of the present invention, the housing 107 of the upper part represents the body of the upper part 111 in the form of "boxes", in which the stack is placed, the display 115 (visible from the rear of the upper part), 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 a matrix of lenses where the lenses are svetosobirayushchim means 109. Every svetosobirayushchim tools are designed to collect light from each led and converting the collected light into light beams 113 from the light sources. The upper part is attached to the bracket can be rotated by means of two bearings 127 slope, which is supported by the bracket 105. The motor 129 tilt to rotate the upper part by means of a belt 131 in the womb, attached to one of the bearings 127 slope. The bracket includes two interconnected shell portion 132 of the bracket mounted on the frame 134 of the bracket, on which the bearings and tilt motor tilt motor pan and bearing pan. PCB 123 contains LEDs light emitting diodes and together with the light-harvesting means 109 in the matrix of the lens forms the light beams from the light sources. The main PCB contains circuitry and control (not shown) designed to control the LEDs and known from the prior art for lighting devices. In addition, the main circuit Board contains switches (not shown) passing through holes in the housing 111 of the upper part. These switches and display work as a user interface, allowing the user to interact with the lamp with a movable upper part.

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

This is a known lighting device uses LEDs to replace a single light source, known until the led component as a widely used light source. However, such lighting device changes its appearance, because the light sources are now open for the viewer and the light emitted 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, it requires a more uniform, smooth output radiation to avoid cheap-looking "fair" view of the excessive number of light sources.

The lighting device according to Fig.1A and 1b is only one known example of the lighting device, and specialist it is clear that there are many different examples of implementation offered by many manufacturers.

In Fig.2A and 2b shows the simplified is hydrated embodiment of the lighting device 201 according to the present invention, where in Fig.2A shows a top view, and Fig.2b shows a transverse view in section along line a-A.

The lighting device 201 includes the first group of sources 203 light (indicated by white boxes) located on the printed circuit Board 204. Svetosobirayushchim means 205 are located above sources 204 light and collect the light from the first group of light sources and convert the collected light into light beams 207 from the light sources. Svetosobirayushchim means 205 can be made in the form of any optical component capable of collecting light from the light source and to convert the light into light beams, and can, for example, be optical lenses, mixing light units, lenses with the effect of total internal reflection, and so on, In the shown embodiment, the implementation of the present invention svetosobirayushchim means 205 is made in the form of lenses with the effect of total internal reflection used in the prior art, and professional clear the lens effect of total internal reflection can be developed in accordance with the light output of the light source and described the optical properties of the light beam 207 from the light source. Light beams 207 are combined into one large light beam with increasing distance from the lighting device.

The second group of light sources is located in the matrix of pixels 209 (shown as black boxes). Each pixel 209 contains at least one light source and is located on the circuit Board 210, and each pixel can be individually controlled by a controller (not shown), for example, to change the color or intensity. Each pixel is designed to emit light in many directions (shown by arrows 211), resulting pixels can be observed from different directions. In addition, at least one of the pixels is designed to emit light in the region between the at least two light beams 207 of the light source. The region between the at least two light beams of the light source can be defined as all points visible from above light beams from the light sources lying on a straight line that intersects at least part of both light beams. It should be noted that there are many straight lines crossing at least part of both light rays and, thus, the area between the two light beams from the light source is a surface. In addition, it should be noted that physically this area can be below the light source, although when observed from above it seems that it is located between the light sources. Printed circuit Board contains a hole for accommodating the light-harvesting means 205.

The result could be the ü create a new effect light, because the area between the light rays can be lit pixels and can, thus, be designed to emit different color different from the color of the first group of light sources. This species may be dynamic, subject to independent control of the first group of light sources and the second group of light sources, which is known in the technical field of lighting in the entertainment industry. The pixels can also be designed to emit light having essentially the same color that the light emitted from the first group, whereby the area between the light beams from the light sources will be filled with essentially the same color as the light source. The second group of light sources can also be used as a display device, because each pixel can be controlled individually, and the second group of light sources can thus use the existing graphical content, observed from different directions. The lighting device according to the present invention can thus be used as a display device and as a lighting device.

A known example of the lighting device shown in Fig.1A and 1b, it can be upgraded to a lighting device according to the present invention means the execution of the holder 125 lens as a printed circuit Board with holes, which can be located svetosobirayushchim means 109, and the installation of the pixels in the regions between the means 109. In accordance with another variant of realization of the present invention a printed circuit Board containing the pixel may be located in the original holder 125 lens. The original LEDs 124 (see Fig.1b) and added LEDs (not shown in Fig.1b), respectively, are designed to work as the first group and second group of light sources that can be controlled separately, where the second group of light sources is located in the matrix of pixels. Specialist it is clear that the components of the lighting prior art also must be replaced to control the first and second group of light sources. This can, for example, be achieved through the implementation of the lighting device shown in Fig.3.

In Fig.3 shows a block diagram of the lighting device 201 according to the present invention. The lighting device includes unit 301 of the control that contains the processor 303 and the storage device 305. The first group of sources of light 203 and the second group of sources of light 209 is attached to the block 301 management and are in accordance with the present invention. The second group of light sources, thus, is located in the matrix of pixels 209a-d.

The processor acts as the means of control and is designed to control the first group of sources of light 203 and the second group of sources 209 light separately. In other words, the management tool can manage one of the groups of light sources, not driving the other group of light sources. This control may, for example, to control the color and/or intensity of the light sources and can be based on any type of communication signals, known in the technical field of lighting, such as signals with pulse-width modulation, amplitude-modulated signals, frequency modulated signals, binary signals, etc. First group 203 and the second group 209 light sources can thus be controlled separately and independently from each other and these groups can thus be considered as two separate and independent groups of light sources. In addition, tools 301 control can control every pixel 209a-d of the second group of light sources individually, as shown by the arrows 308a-d, which means that the controls can control every pixel that is not driving the other pixels. Each pixel 209a-d can be attached, as shown, to the control unit via a separate communication line, however, it is also possible to connect the pixels to the same communication line and use addressing, known in the technical field of display systems.

Tools 301 controls are designed to control the first group of light sources on the OS the implement input signal 311, indicating at least one parameter of the color. The input signal 311 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. Parameter light can, for example, contain information about the color and brightness, which is supposed to form the first group of light sources. However, the parameter of the light can also contain information about the other parameter known in the technical field of lighting in the entertainment industry, such as the position of the lamp with a movable upper part, about the level scaling in the case of using the lamp as a system scaling, frequency Gating and so on

Tools 301 controls are also designed to work as a means of videopremiere used to control the pixels on the basis of the video signal 313. The video signal can be any signal that contains video/pixel/graphic information, and can be served using any communication Protocol suitable for transmitting video/pixel/graphic information. In addition, when estva videopremiere can be used for receiving video signal from the storage device 305, which, for example, may store different video.

The input signal may, for example, contain information about the first target color in the form of any parameter that determines the color of the light, which should form the first group of light sources, for example the RGB values of the color coordinates on the chromaticity diagram, etc. controls can be designed to control the second group of light sources based on an input signal indicating the first target color, whereby the second group of light sources may also be used for the formation of essentially the same color that 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 matrix was adjusted so that the color of the second group of light sources differed, but was aesthetically coordinated with the color from the first group according to a predefined color scheme. The input signal may also contain information about the 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.

In Fig.4 shows a block diagram of the lighting system 401 according to the present invention. Lighting system 401 includes a Central controller 403, which is connected with lighting devices 201a-201i and the panel is engaged them. Lighting devices 201a-201i made according to the present invention and as described above. Expert it is clear that other types of lighting devices may also be included in the lighting system. The Central controller 403 may be made in the form of a light controller or media server, known in the technical field of lighting for the entertainment industry and, for example, may be of the type supplied by the applicant. The Central controller 403 includes means to transmit a signal 311 of the incoming light on the lighting device 201a-201i, and lighting devices 201a-201i use this signal on the incoming light to control the first group of light sources as described above. In this embodiment implementation of the present invention device 201a-201i are connected in series, as is well known according to the DMX Protocol used for signal transmission of the incoming light. The Central controller 403 also includes a means of transmitting the input video signal 313 (shown as dotted lines) of the lighting device 201a-201i, and lighting device a-201 use this signal to control the pixels of the second group of light sources as described above. In this embodiment implementation of the present invention, the input signal also uses a serial connection, however, the specialist p is clear, the input signal can be served individually to each lighting device 201a-201i, what is known in the technical field of display systems. For example, you can distribute the video signals using the Protocol RH, currently supplied by the applicant. In the illustrated implementation of the present invention the lighting device 201a-201i are arranged in a 3×3 matrix, and the Central controller is designed to split the video/graphic material into parts and distribute each part on different lighting devices. In the whole matrix can be used to create a single visual display. The first group of light sources of lighting devices 201a-201i can be used to create lighting effects in the airspace. In the case of integration of the lighting device in the upper part of the lamp with a movable upper part of the entire matrix can be displaced, by means of what can be created with new and existing lighting effects and visual effects.

In Fig.5A-C shows another embodiment of the lighting device 501 according to the present invention. In Fig.5A shows the top view of Fig.5b shows a cross-section along the line B-B, and Fig.5 shows a top view with the remote light-diffusing coating.

The lighting device 501 contains the light sources, collected in the first group of sources 503 light (indicated by white boxes) and the second group of sources 505 light (indicated by black boxes). As described above, the light sources of the second group are arranged in a matrix of pixels and each pixel represents at least one light source, which can be controlled individually, for example, to change the color or intensity. Svetosobirayushchim means 509 is located above the light sources of the first group 503 and around them and are designed to collect light from the first group of light sources and converting the collected light into light beams 511 from light sources. Svetosobirayushchim means 509 can be made in the form of any optical component capable of collecting light from the light source and to convert the light into light beams, and can, for example, be optical lenses, mixing light units, lenses with the effect of total internal reflection, and so on, In the shown embodiment, the implementation of the present invention svetosobirayushchim means 509 is made in the form of lenses with the effect of total internal reflection used in the prior art, and professional clear the lens effect of total internal reflection can be developed in accordance with the light output of the light source and is described on the optical properties of the beam 511 from the light source. Light beams 511 are connected in one large light beam as the distance from the lighting device. Each scattering site receives light from one pixel and, thus, it can be used to create a graphical picture.

The lighting device comprises a diffusing coating 513 located above the circuit Board 507, and this scattering coating contains at least one dispersing section 515 and at least one merseyway section 517. The scattering plots 515 receive the light formed by the second group of light sources 503 and diffuse the received light in many directions, shown by arrows 519. 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 species may be dynamic in the management of the first group of light sources and the second group of light sources separately, which is known in the field of lighting design in the entertainment industry. The second group of light sources can also be designed to emit light having essentially the same color as the light emitted from the first group, resulting in a surface lighting device is seen as one surface with a uniform color. The scattering sites can b shall be located between pressively sites resulting avoid point of view, because the area between pressively areas now have essentially the same color that the light beams 511 emerging from the lighting device through nerasseivayushchee areas.

In Fig.6A and 6b are shown respectively a perspective view and a side view of the lighting device according to Fig.1A-1b, modified in the lighting device according to the present invention, as described in Fig.5A-5C.

In this embodiment, the implementation of LEDs 601 (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 are designed to work as, respectively, of the first group and second group of light sources that can be managed separately.

In addition, the housing upper part contains the scattering coating 603 (remote from the housing in Fig.6A and installed in Fig.6b) containing at least one dispersing section 615 and at least one merseyway section 617. The scattering plot is tough 617 receive at least a portion of the light, formed the second group of light sources, and diffuse the received light, as indicated by the arrows 619 (for the sake of simplicity they are shown only in Fig.6b). At least part of the light beams 613 from the light sources passes through nerasseivayushchee sections 615 without scattering. It should be noted that for the sake of simplicity, shows only some of the light beams from the light sources. In the point view of the LEDs on the front disappears by lighting a light-diffusing coating the emission of light scattering plots and pressively areas, and the area between the lenses, lighted existing internal scattered light from the LEDs to diffuse into the surrounding space. Since each pixel can be controlled individually, the scattering region 615 can be used to view video/graphic material.

At least part of the scattering coating 603 protrudes from the housing and, therefore, part of light scattered sideways and backward (as shown by arrows a) relative to the light beams from the light sources. The scattering plots of the scattering of the coating can be lighted up because of the surface and on the side and, thus, act as a light guide. As a consequence, provided the opportunity of reviewing the lamp at different angles, and acting svetonoscev the total coating gives the lamp a new lighting effect.

Nerasseivayushchee plots can be made in the form of transparent areas is a type of flat transparent surfaces located above the light-harvesting tools. Such a flat transparent surface enable light beams from the light sources to pass through without scattering. Although the transparent areas can be designed to adjust the divergence of the light beam from 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 the areas intended for placement of the scattering area. Scattering coating may also be molded using forms made 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 the light-harvesting tools.

Scattering coating may also contain a means of attachment, enabling the user to attach the scattering floor to the lighting device. Thus, the scattering floor mo is et to be a standard feature or optional. Execution of the scattering of the coating as a disposable accessories allows the user to use the device with the scattering coating and without it. As a result, when using the lighting device without scattering coating the second group of light sources is visible as a clear pixels, and the illuminating device with the scattering coating each pixel will be smoothed.

In Fig.7a-7d shows another embodiment of the lighting device 701 according to the present invention. In Fig.7a shows a top view, and Fig.7b shows a top view of a remote fiber and the light-harvesting means. In Fig.7C and 7d shows a cross-sectional view along lines C-C and D-D, respectively.

The lighting device 701 includes the first group of sources 703 light (shown as white boxes) located on the printed circuit Board 704. Svetosobirayushchim means 705 is located above sources 703 light, and svetosobirayushchim means 705 collect light from the first group of light sources and convert the collected light into light beams 707 from light sources. Svetosobirayushchim means 209 may be made in the form of any optical component capable of collecting light from the light source and to convert the light into light beams, and can, e.g. the measures to be optical lenses, mixing light units, lenses with the effect of total internal reflection, and so on, In the shown embodiment, the implementation of the present invention svetosobirayushchim means 705 is made in the form of lenses with the effect of total internal reflection used in the prior art, and expert it is clear that the lens effect of total internal reflection can be developed in accordance with the light output of the light source and described the optical properties of a light beam 707 from the light source. Light beams 707 are connected in one large light beam with increasing distance from the lighting device.

The second group of light sources is located in the matrix of pixels (shown as black boxes), and each pixel contains at least one light source and can be controlled individually, for example, to change the color or intensity. In this embodiment implementation of the present invention the part of the pixels 709 is located on the printed circuit Board 704, and the other part 710 pixels located vertically standing on printed circuit boards 711 perpendicular relative to the printed circuit Board 204.

In addition, the lighting device 701 includes a fiber optic cable containing the input section and output section. The light guide receives light, formed one of the pixels in the input the second section, and transmits the received light to the output section, which is designed to emit the received light in the region between the at least two light beams 707 from the light source.

For example, as shown in Fig.7C, the light sources a and 709b emit light rays (shown as thin solid lines), which are, respectively, the optical fibers a and 713b in the input sections a and 715b and out of optical fibers in the output sections a and 717b, as shown by the arrows 719. In addition, as shown in Fig.7d, the sources a and 710b emit light rays (shown as thin solid lines), which are, respectively, the optical fibers a and 714b in the input sections a and 716b and out of optical fibers in the output sections a and 718b, as shown by arrows 720. Fiber optic cables are designed for transmission of light emitted by each pixel in the region between the light beams from the light sources, and light is emitted in many directions. Fiber optic cables are made of solid transparent material, and light rays entering in the input section, will undergo internal reflection to the output section, where they will exit the light guide.

The output section is designed to output light beams from the light guide. This can, for example, be performed by adjusting the surface roughness of the fiber in the output sections, resulting in light rays do not feel full the internal reflection at the drop of a rough surface and, thus, the light exits the light guide. Alternatively, the surface of the fiber may be coated with a material that scatters light incident on the output section. Another option is to tilt the upper and lower surfaces of the light guide relative to each other, which will result in a change in the angle of incidence of light rays propagating inside the light guide. The light guide and the output device may, for example, be performed using methods known in the field of engineering background light from the television screens and/or cell phones.

In the illustrated implementation of the present invention the output section are arranged in a predictable way, and the light, thus, emerges from the fiber only in these areas. In the second group of light sources can be used to create an optical pattern between light rays and the optical film can be used to create lighting effects available for observation by a viewer looking at the lighting device. Pixels and various parts of the optical pattern can be controlled separately, for example by means of on/off, changing the color of certain parts of the predetermined pattern. A predetermined pattern can thus be used as a dynamic picture, the IP is olzoeva to create some interesting lighting effects. However, it is also possible to arrange the output sections of the optical fibers in a matrix containing n rows and m columns.

Fiber optic cables are made in the form of the individual optical fibers that carry light from each pixel in the region between the light beams from the light sources. For example, the optical fibers can be performed as shown in Fig.8A and 8b. In the illustrated implementation of the present invention, fiber optic cables and svetosobirayushchim means supported solid 722 made in the form of a disk. This solid-state element contains openings intended for the location of the light-harvesting means 705 and fibre 713 and 714.

Alternatively, a separate optical fibers, the optical fibers can be made in the form of a single fiber, and the pixels are made with the possibility of introducing light into the light guide and the light from different pixels out in different places. Such a single fiber can, for example, be solid transparent disk (or have any other form), where the pixels are designed to emit light through a transparent disk side and the light emerges from the disk on its front surface.

The lighting device 701 may also include a third group of light sources (not shown) located on the printed circuit Board 704 and a light-diffusing parts (not shown) located between the at least two light the new beams from the light sources and/or at least towards the output sections of the optical fibers. The scattering plots are used for receiving light from at least one light source of the third group of light sources and scattering of the received light. The scattering regions can, for example, be obtained by performing a rigid body 722 of transparent material and impart light-diffusing properties to the areas between the light-harvesting means 705 and/or fibers 713 and 714. The third group of light sources may be located in the pixels in the second group of light sources and can, thus, be used for the education of graphic materials.

In Fig.8A and Fig.8b respectively show two types of fibers used in Fig.7a-7d. The light guide according to Fig.8A corresponds to the light guide a intended for receiving the light from sources a light, arranged in a circle around the PCB 704. This fiber is made of a transparent rod 801 containing the input section a and the output section a. The output section represents one surface of the rod and processed so that the light emerges from the surface as shown by arrows 720. In this embodiment implementation of the present invention the source a light is a light source with 4 crystals (crystals creating red R, green G, blue b and white W color) in one led and capable, is so to create a variety of colors by additive color mixing. Light rod also promotes the mixture of colors from the 4 crystals LEDs. The light guide shown in Fig.8b corresponds to the light guide a intended for receiving the light from the light sources a on the printed circuit Board 207 through the input section a. This fiber contains a curve 803, designed to reflect light coming from the input section toward the output section a. It should be noted that:
