    Descriptive Report of the Invention Patent for “LIGHTING DEVICE”.
    Field of invention
    [0001] The present invention relates to the lighting device, which comprises a number of light sources and a number of light collecting means arranged in a housing. The number of light collection means collects light from at least one of the light sources and converts the collected light into a number of light source beams, and the light source beams are emitted from the said housing.
    Fundamentals of the invention
    [0002] Fixtures that create varied effects are being used more and more in the entertainment industry, in order to create various lighting and lighting effects for application in live shows, TV programs, sporting events, or as a part in the architectural installation .
    [0003] Entertainment luminaires typically create a beam of light having a beam width and divergence and can, for example, be flood luminaires, creating a relatively wide beam of light with a uniform light distribution, or they can be electrical devices profile, adapted to project an image on a target surface. There is a trend that more and more this type of electrical device is used in each show or each installation, and the devices are, as a consequence, more visible to sectors or viewers. The luminaires usually create the lighting effect at a distance from the luminaire itself, and the luminaire is therefore not as interesting and aesthetic to look at. The device manufacturers try, as a consequence, to provide the devices with aesthetic designs in order to make them more interesting to look at. However, this is very difficult, as the housing of the devices usually depends on physical requirements

    2/21 defined by the technical specifications of the device, such as optics, mechanics, electronics, refrigeration, etc.
    [0004] The LED component as a light source has changed the appearance of most luminaires, when using multiple LEDs to replace a single light source. This applies to all lighting industries - general, domestic, industrial, entertainment, etc. The most visible change is that all the multiple light sources are now exposed to the viewer and the light emits from a larger area. Now that most LED luminaires have visible light-emitting diodes, some customers don't like the look of multiple light points. Instead, a more uniform light output is requested, in order to avoid the cheap “amusement park” aspect with a large number of light sources. The amusement park aspect appears both in luminaires that mix colors before the light is emitted from the accommodation, and in luminaires where colors are mixed in the air or on the wall.
    Description of the Invention
    [0005] The purpose of the present invention is to resolve the above described limitations related to the state of the art. This is achieved through a lighting device and lighting system as described in the independent claims. The dependent claims describe possible embodiments of the present invention. The advantages and benefits of the present invention are described in the detailed description of the invention.

    Detailed Description of the Invention
    [00014] The present invention is described with a view to a movable luminaire head including a number of LEDs that generate a beam of light, however the one skilled in the art realizes that the present invention refers to lighting devices using any type of light source such as discharge lamps, OLEDs, plasma sources, halogen sources, fluorescent light sources, etc. and / or combinations thereof. It should be understood that the illustrated modalities are simplified and illustrate the principles of the present invention, rather than showing an exact modality. One skilled in the art will understand that the present invention can be incorporated in many different ways and also include more components in addition to the components shown.
    [00015] Figures 1a-1b illustrate a lighting device according to the state of the art, where Fig. 1a is a perspective view and Fig. 1b is an enlarged view. The lighting device is a movable luminaire head 101, comprising a base 103, a yoke 105 rotationally connected to the base and a
    Petition 870190132792, of 12/13/2019, p. 6/32
    4/21 swivel head 107 connected to the yoke.
    [00016] In the illustrated embodiment, the head comprises a number of light sources and a number of light collecting means 109 arranged in the head housing 111. The light collecting medium collects light from the light sources and converts the collected light in a number of light source beams 113 (single illustrated), which are emitted from the housing.
    [00017] In the illustrated embodiment, the head housing 107 is a bucket-shaped housing 111 where a display 115 (visible from the rear of the head), main PCB (printed circuit board) 117, a fan 119, a heatsink of heat 121, an LED PCB 123 and a set of lenses are stacked. The LED PCB 123 comprises a number of LEDs 124 and the lens set consists of a lens holder 125 and a lens array, where the lenses constitute the light collecting medium 109. Each light collecting medium is adapted to collect light from each LED and convert the collected light into a series of light source beams 113. The head is rotationally connected to the yoke by two tilt bearings 127, which are supported by yoke 105. A tilt motor 129 is adapted to rotate the head through a tilt belt 131 connected to one of the tilt bearings 127. The yoke comprises two interconnected parts 132 that are mounted on a yoke frame 134 in which the tilt bearings, the tilt motor and the bearing are willing. The LED PCB 123 comprises a number of LEDs that emit light and which, in cooperation with the light collecting medium 109 in the lens array, generates a number of light source beams. The main PCB comprises control circuits and driving circuits (not shown) to control the LEDs as known in the lighting device art. The main PCB further comprises a series of switches (not shown) that span a series of holes
    Petition 870190132792, of 12/13/2019, p. 7/32
    5/21 in the head housing 111. The switches and the display act as a user interface, allowing a user to communicate with the moving head lamp.
    [00018] The yoke is connected to a bearing 133 rotationally connected to the base 103. A tilt motor 135 is adapted to rotate the yoke through an inclination belt 137 connected to bearing 133. The base comprises 5 5-pin XLR male connectors 139 and female 141 for DMX signals as known in the entertainment lighting technique; input 143 and output 145 connectors, power supply PCBs (not shown) and fan (not shown). The fan forces air into the base through ventilation holes 147.
    [00019] This state of the art lighting device uses multiple LEDs to replace a single light source as known prior to the introduction of the LED component as a widely used light source. However, such a lighting device changes its visible appearance as the multiple light sources are now exposed to the viewer and the light emits from a larger area. If the luminaires are a color mixing version with single color LEDs, then all the LED colors used are visible. However, some customers do not like looking at multiple points of light. Instead, a more uniform output is requested to avoid the cheap look of an amusement park with a lot of light sources.
    [00020] The lighting device illustrated in Figs. 1a and 1b is just one example of a state of the art lighting and one skilled in the art realizes that there are a large number of different modes provided by a large number of manufacturers.
    [00021] Figures 2a-b illustrate a simplified modality of
    Petition 870190132792, of 12/13/2019, p. 8/32
    6/21 lighting device 201 according to the present invention, where Fig. 2a shows a top view and Fig. 2b shows a cross-sectional view along line A-A.
    [00022] The lighting device 201 comprises a first group of light sources 203 (illustrated as white squares) mounted on a PCB 204. A number of light collection means 205 are arranged above the light sources 204 and the means of light collection 205 collect light from the first group of light sources and convert the collected light into a series of light source beams 207. The light collection means 205 can be incorporated as any optical component capable of collecting light from sources and convert light into beams of light, and can, for example, be optical lenses, light mixers, TIR lenses, etc. In the illustrated embodiment the light collection means 205 are incorporated as TIR lenses, as known in the prior art, and those skilled in the art realize that the TIR lens can be designed according to the light output of the light source and the properties described optics of the light source beam 207. The light beams 207 will merge into a large beam of light as the distance to the lighting device increases.
    [00023] A second group of light sources is arranged in a 209 pixel matrix (illustrated as black squares). Each pixel 209 comprises at least one light source and is arranged on a PCB 210, and each pixel can be controlled individually by a controller, not shown, for example, to change color or intensity. Each pixel is adapted to emit light in several directions, as illustrated by the arrows 211 according to which the pixels can be observed from several directions. At least one of the pixels is adapted to emit light in an area between at least two of the 207 light source beams. The area between at least two light source beams can be defined as all the points that, seen from above the
    Petition 870190132792, of 12/13/2019, p. 9/32
    7/21 beams of light source, rest in a straight line that intersects at least part of the two beams of light. It should be understood that many straight lines will intersect at least part of the two light beams, and the area between the two light source beams thus constitutes a surface. In addition, it should be understood that the area can physically rest below or above the light sources, as long as it appears to be between the light sources when viewed from above. The PCB is provided with a number of holes, adapted to accommodate the 205 light collection means.
    [00024] The consequence is that a new light effect can be created, since the area between the light beams can be illuminated by the pixels and, therefore, can be adapted to emit a different color than the first group of light sources. This aspect can be dynamic if the first group of light sources and the second group of light sources are individually controlled as known in the entertainment lighting technique. The pixels can also be adapted to emit light having substantially the same color as the light emitted by the first group, whereby the area between the beams of light sources is filled with substantially the same color as the light source. The second group of light sources can still be used as a video display, as each pixel can be controlled individually, and the second group of light sources can thus use the present graphic content that can be viewed from several directions. The lighting device according to the present invention, therefore, can be used as a video display and lighting device.
    [00025] As an example, the state of the art lighting device illustrated in Fig. 1a and 1b can be upgraded to a lighting device according to the present invention, incorporating lens holder 125 as a PCB with a number
    Petition 870190132792, of 12/13/2019, p. 10/32
    8/21 holes in which the light collecting means 109 can be arranged, and mounting the pixels in the areas between the light collecting means 109. Alternatively, a PCB comprising the pixel can be arranged in the original lens holder 125 The original LEDs 124 (see Fig. 1b) and the added LEDs (not shown in Fig. 1b) are adapted to function as, respectively, a first and a second group of light sources that can be individually controlled, where the second group of light sources is arranged in a matrix of pixels. One skilled in the art will realize that the state of the art lighting components also need to change in order to control the first and second group of light sources. For example, this can be achieved by incorporating the lighting device, as illustrated in Fig. 3.
    [00026] Fig. 3 illustrates a block diagram of the lighting device 201 according to the present invention. The lighting device consists of a control unit 301 comprising a processor 303 and a memory 305. The first group of light sources 203 and the second group of light sources 209 are connected to the control unit 301 and arranged according to the present invention. The second group of light sources is thus arranged in a 209a-d pixel matrix.
    [00027] The processor acts as a control means and is adapted to control the first group 203 of light sources and the second group 209 of light sources individually. That is, the processing means can control one of the groups of light sources without controlling the other group of light sources. The control can, for example, be adapted to control the color and / or the intensity of the light sources and can be based on any type of communication signals known in the lighting technique, for example, PWM, binary AM, FM signals , etc. The first 203 and the second group 209 of
    Petition 870190132792, of 12/13/2019, p. 11/32
    9/21 light sources can therefore be controlled individually and independently of each other, so they can be treated as two groups, individually and independently of the light sources. Control means 301 can further control each pixel 209-d of the second group of light sources individually as indicated by arrows 308a-d. That is, the processing means can control each pixel without controlling other pixels. Each 209-d pixel can be connected to the control unit via a communication line, as illustrated, however it is also possible to connect the pixels to the same communication line and use addressing, as known in the visualization systems technique.
    [00028] Control means 301 are adapted to function as a light control means, adapted to control the first group of light sources based on a light input signal 311 indicative of at least one light parameter. Input signal 311 can be any signal capable of communicating parameters and can, for example, be based on one of the following protocols USITT DMX 512, USITT DMX 512 1990, USITT DMX 512-A, DMX-512-A, including RDM as covered by ANSI E1.11 and ANSI E1.20 or Wireless DMX standards. ACN stands for Architecture for Control Networks; ANSI E1.17 - 2006). The light parameter can, for example, be indicative of the color and brightness that the first group of light sources should generate. However, the light parameter can also be indicative of another parameter, such as the position of a moving head luminaire, zoom level, if the luminaire has a zoom system, strobe speed, etc. as known in the entertainment lighting technique.
    [00029] Control means 301 are also adapted to act as a video control means, adapted to control pixels based on a 313 video signal. The video signal can be
    Petition 870190132792, of 12/13/2019, p. 12/32
    10/21 any signal comprising video / pixel / graphic information and can be provided using any appropriate communication protocol to communicate video / pixel / graphic information. The video control means can further be adapted to receive the video signal from memory 305 which, for example, can store different video content.
    [00030] The input signal can, for example, be indicative of a first target color, any parameter that defines the color of the light that the light sources of the first group must generate, for example, RGB values, color coordinates in color maps, etc. The control means can be adapted to control the second group of light sources based on the input signal indicative of the first target color by which the second group of light sources can be adapted to generate substantially the same color as the color generated by the first group of light sources. However, it is also possible to integrate a color scheme so that the color of the second matrix is adjusted so that the color of the second group of light sources is different, but that they combine aesthetically according to a predetermined color scheme. The input signal can also be indicative of a second target color and the color of the second group of light sources can be controlled based on this second target color parameter.
    [00031] Fig. 4 illustrates a block diagram of a 401 lighting system according to the present invention. The lighting system 401 consists of a central controller 403 connected to and which controls a number of lighting devices 201a-201i. The lighting devices 201a-201i are incorporated in accordance with the present invention and as described above. One skilled in the art realizes that other types of lighting devices can also be included in the lighting system. The controller
    Petition 870190132792, of 12/13/2019, p. 13/32
    11/21 central 403 can be incorporated as a light controller or as a media server, as known in the entertainment lighting technique and, for example, of a type provided by the depositor. Central controller 403 comprises means for communicating a light input signal 311 to lighting devices 201a201i and lighting devices 201a-201i use this light input signal to control the first group of light sources, as described above . The lighting devices 201a-201i in this mode are changed as known according to the DMX protocol, which is used to communicate the light input signal. Central controller 403 also comprises means of communicating a video input signal 313 (illustrated in dotted lines) to lighting devices 201a-201i and lighting devices 201a-201i use this video signal to control the pixels of the second group of light sources, as described above. In this modality the video input signal is also changed, however the one skilled in the art realizes that the video input signal can be fed individually for each lighting device 201a-201i, as known in the visualization systems technique. For example, it is possible to distribute video signals using the P3 protocol currently provided by the depositor. In the illustrated modality the lighting devices 201a-201i are arranged in a 3x3 matrix and the central controller is adapted to divide the video / graphic content into subparts and distribute each subpart to the different lighting devices. As a consequence, the entire matrix can be used to create a display. The first group of light sources from the 201a201i lighting devices can be used to create effects in the air. In the event that the lighting devices have been integrated into the head of a moving head luminaire, the entire matrix can be moved, whereby
    Petition 870190132792, of 12/13/2019, p. 14/32
    12/21 new and existing video and light effects can be created.
    [00032] Figures 5a-c illustrate another embodiment of the lighting device 501 according to the present invention. Fig. 5a shows a top view, Fig. 5b shows a cross-sectional view along line B-B and Fig. 5C shows a top view with the diffuser cover removed.
    [00033] The lighting device 501 comprises a number of light sources arranged in a first group of light sources 503 (indicated as white squares) and in a second group of light sources 505 (indicated as black squares). As described above, the light sources of the second group are organized into a matrix of pixels and each pixel comprises at least one light source and can be controlled individually, for example, to change color or intensity. A number of light collection means 509 are arranged above and around the light sources of the first group 503 and are adapted to collect light from the first group of light sources and convert the collected light into a series of light source beams. light 511. Light collection means 509 can be incorporated as any optical component capable of collecting light from light sources and converting light into light beams and can be, for example, optical lenses, light mixers, TIR lenses, etc. In the illustrated embodiment the light collection means 509 are incorporated as TIR lenses, as known in the prior art, and the person skilled in the art realizes that the TIR lens can be designed according to the light output of the light source and the properties described optics of the 511 source light beam. The 511 light beams will merge into a large beam of light as the distance to the lighting device increases. Each diffusing region diffuses light from one pixel and each diffusing region can therefore be used to create a graphic pattern.
    [00034] The lighting device consists of a cover
    Petition 870190132792, of 12/13/2019, p. 15/32
    13/21 diffuser 513 disposed above the PCB 507 and the diffuser cover comprises at least one diffuser region 515 and at least one non-diffuser region 517. The diffuser regions receive 515 light generated by the second group of light sources 503 and diffuse the received light in several directions, as illustrated by arrows 519. The consequence is that a new light effect can be created, since the area between the light beams may have another color emitted by the second group of light sources. This aspect can be dynamic if the first group of light sources and the second group of light sources are individually controlled, as known in the entertainment lighting technique. The second group of light sources can also be adapted to emit light, having substantially the same color as the light emitted by the first group, in which the surface of the lighting device appears as a surface of the same color. Diffusion regions can be arranged between non-diffusing regions, where the dotted appearance can be avoided, as areas between non-diffusing regions now have substantially the same color as the 511 light beams exiting the lighting device through the regions not diffusers.
    [00035] Fig. 6a and Fig. 6b are respectively a perspective view and a side view of the lighting device of Figs. 1a-1b, which has been modified in a lighting device, according to the present invention, as described in Figs. 5a-5c.
    [00036] In the present modality, a series of LEDs 601 (illustrated as black squares) were mounted on the lens holder 125 between the light collecting means 109. This can be achieved, for example, by incorporating the lens holder as a PCBs with a number of holes in which the light collecting means can be arranged, or by adding a PCB to the original lens holder. The original LEDs 124 (see Fig. 1b) and the added LEDs 301 are adapted for
    Petition 870190132792, of 12/13/2019, p. 16/32
    14/21 function as a first group and a second group of light sources that can be individually controlled. [00037] The head housing comprises a diffuser cap 603 (enlarged from the housing in Fig. 6a and mounted in Fig. 6b) comprising at least one diffusing region 615 and at least one non-diffusing region 617. The diffusing regions 617 receive at least at least a part of the light generated by the light sources of the second group and diffuse the received light, as indicated by arrows 619 (only shown in Fig. 6b, for the sake of simplicity). At least part of the number of light source beams 113 passes through the non-diffusing regions 615 without being diffused. It should be noted that only a few of the light source beams are illustrated for simplicity. The result is that the dotted aspect of the front of the LED is removed, illuminating the diffusing cap as light is emitted from the non-diffusing and diffusing regions, and the areas between the lenses are illuminated with the existing internal light from the LEDs that are diffused in the surroundings. Since each pixel can be controlled individually, the 615 broadcast regions can be used to display video / graphic content. [00038] At least a part of the diffusing cover 603 protrudes from the housing and a part of the light is diffused as a consequence to the sides and back (as indicated by the arrows 619a) in relation to the light source beams. The diffuser regions of the diffuser cover can be illuminated behind the surface and on the side and thus act as a light guide. The luminaire can therefore be viewed from multiple angles, and the protruding diffuser cover provides a new light effect for the luminaire.
    [00039] Non-diffusing regions can be incorporated as clear areas, like transparent flat surfaces arranged above the light collecting means. These flat transparent surfaces will allow the light beams to pass through without diffusing the source beams
    Petition 870190132792, of 12/13/2019, p. 17/32
    15/21 light. However, the light areas can be adapted to adjust the divergence of the light beam, but the output light beam will remain a well-defined light beam. Non-diffusing regions can be incorporated as clear areas as transparent flat surfaces arranged above the light collection means. Such transparent flat surfaces will allow the light source beams to pass without diffusing the light source beams. However, the light areas can be adapted to adjust the divergence of the light beam, but the output light beam will remain a well-defined light beam. The diffuser cover can still be molded where the molds are adapted to define the non-diffusing and diffusing regions. The non-diffusing regions can also be incorporated as an opening or cuts arranged above said means of collecting light.
    [00040] The diffuser cover can also include fixing means, which allow the user to affix a diffuser cover to a lighting device. The diffuser cover can therefore be supplied as a standard component or as an optional accessory. Incorporating the diffuser cover as a removable accessory gives the opportunity to use the lighting device with and without the diffuser cover. The result will be the fact that the second group of light sources looks like a clear pixel when the lighting device is used without the diffuser cover, and that each pixel appears as a softer pixel when the lighting device is used with the diffuser cover.
    [00041] Figures 7a-7d illustrate another embodiment of a lighting device 701 according to the present invention. Fig. 7a is a top view and Fig. 7b is a top view with the light guides and light collection means removed. Figs. 7c and 7d are cross-sectional views along the line C-C and D-D respectively.
    Petition 870190132792, of 12/13/2019, p. 18/32
    16/21
    [00042] The lighting device 701 comprises a first group of light sources 703 (illustrated as white squares) mounted on a PCB 704. A number of light collecting means 705 are arranged above the light sources 703 and the means of light collection 705 collect light from the first group of light sources and convert the collected light into a series of light source beams 707. The light collection means 705 can be incorporated as any optical component capable of collecting light from light sources. light and convert light into light beams, and can, for example, be optical lenses, light mixers, TIR lenses, etc. In the illustrated embodiment, the light collection means 705 are incorporated as TIR lenses, as known in the prior art, and the person skilled in the art realizes that the TIR lens can be designed according to the light output of the light source and the described optical properties of the 707 light source beam. The 707 light beams will merge into a large beam of light as the distance to the lighting device increases.
    [00043] A second group of light sources is arranged in a matrix of pixels (illustrated as black squares) and each pixel comprises at least one light source and can be controlled individually, for example, to change color or intensity. In this embodiment, part of pixels 709 are mounted on PCB 704 and another part 710 of pixels are arranged in a series of upright PCBs 711 that are perpendicular to PCB 204.
    [00044] The lighting device 701 further comprises a number of light guides that include an entry section and an exit section. The light guide receives the light generated by one of the pixels in the input section and transfers the received light to the output section which is adapted to emit the received light in an area between at least two of the 707 light source beams.
    [00045] For example, as illustrated in Fig. 7c, the light source 709a

    17/21 and 709b emits a number of light rays (illustrated as thin solid lines) that respectively enter the light guide 713a and 713b in the input section 715a and 715b and are coupled outside the light guide in the output sections 717a and 717b, as illustrated by arrows 719. As illustrated in Fig. 7d, source 710a and 710b emits a number of light rays (illustrated as thin solid lines) that respectively enter light guide 714a and 714b in 716a and 716b and are coupled outside the light guide in the output sections 718a and 718b, as illustrated by the arrows 720. The light guides are adapted to transfer the light emitted by each pixel to an area between the light source beams and the light is emitted in multiple directions. The light guides are incorporated as a transparent solid material and light rays that enter an entry section will be reflected internally to an exit section where the light rays are coupled outside the light guide.
    [00046] The output sections are adapted to couple the light rays outside the light guide. For example, this can be achieved by adjusting the roughness of the light guide surface in the outlet sections, where the light rays do not have full internal reflection when they reach the rough surface and, as a consequence, the light is coupled outside the light guide. Alternatively, the light guide surface can be treated with a material that will spread the light that reaches the exit section. Another opportunity is to angle the upper and lower surfaces of the light guide in relation to each other, resulting in the fact that the incident angle of the light rays traveling within the light guide will change. The guide light and external coupling can, for example, be constructed using methods known in the art of backlighting TV and / or cell phone screens.
    [00047] In the illustrated mode, the light guide exit sections were arranged in a predetermined pattern and the light will therefore come out of the light guide in these areas. The consequence is that the second
    Petition 870190132792, of 12/13/2019, p. 20/32
    18/21 group of light sources can be used to create an optical pattern between the light beams and this optical pattern can be used to create light effects that can be observed by a viewer looking at the lighting device. The pixels can be controlled individually and the different part of the optical pattern individually, for example, turning on / off, changing color parts of the predetermined pattern. In this way, the predetermined pattern can be used as a dynamic pattern that can be used to create several interesting light effects. However, it is also possible to organize the output sections of the light guides in a matrix with n rows and m columns.
    [00048] The light guides are incorporated as a number of individual light guides that transfer the light from each pixel to an area between the light source beams. For example, light guides can be incorporated as shown in Figs. 8a and Fig. 8b. In the illustrated embodiment, the light guides and light collectors are supported by a solid body 722 formed as a disk. The solid body is constructed with a number of holes adapted to accommodate the light collection means 705 and the light guides 713 and 714.
    [00049] As an alternative to individual light guides, light guides can be incorporated as a single light guide in which the pixels are adapted to couple the light in the light guide and where the light forms the different pixels that are coupled out in different places. Such a single light guide can be, for example, a transparent solid disk (or otherwise) in which the pixels are adapted to emit light on the transparent disk from the side and the light coupled outside the disk on its front surface.
    [00050] The lighting device 701 can also be composed of a third group of light sources (not shown) arranged on the PCB 704 and a number of diffusing regions (not
    Petition 870190132792, of 12/13/2019, p. 21/32
    19/21 shown) positioned between at least two light source beams and / or at least in the light guide exit sections. The diffusing regions are adapted to receive light from at least one of the light sources in the third group of light sources and to diffuse the received light. The diffusing regions can be provided, for example, by incorporating the solid body 722 of a transparent material and providing diffusion properties for the areas between the light collecting means 705 and / or the light guides 713 and 714. The third group of light sources can be organized into pixels as the second group of light sources and therefore can be used to generate graphic content. [00051] Fig. 8a and Fig. 8b illustrate the two types of light guides used in Figs. 7a-7d. The light guide in Fig. 8a corresponds to the light guide 714a which is adapted to receive light from the light sources 710a arranged circumferentially around the PCB 704. The light guide consists of a transparent rod 801 comprising an inlet section 716a and an outlet section 718a. The outlet section constitutes a surface of the rod and has been treated in such a way that the light will be coupled outside this surface, as illustrated by the arrows 720. In this embodiment the light source 710a is a 4 in 1 LED light source that comprises a mold red R, green G, blue B and white W and can thus create a large number of different colors using the additive color mixture. The light rod also helps in mixing the colors of the 4 LED molds. The light guide in Fig. 8b corresponds to the light guide 713a which is adapted to receive light from light sources 709a positioned on PCB 704 through the inlet section 715a. This light guide comprises a bend 803 which is adapted to reflect light from the input section towards the output section 717a.
    [00052] It is noted that:
    - The invention applies to multichip LEDs and color LEDs
    Petition 870190132792, of 12/13/2019, p. 22/32

    - The invention applies to profile and washing luminaires.
    - The invention applies to any light source technology.
    - That the invention eliminates or minimizes the dotted appearance of an LED luminaire with several LED lenses exposed to the viewer.
    - The second group of light source can be used as a new feature of additional effect on the device and works as an eye-catcher, but most importantly, as an individual pixel when used in multi-unit configurations. Thus, it is an air beam and an illuminated surface.
    - The second light source group can also be used to indicate errors or other device status information.
    - The invention creates a possibility to make the light / color visible from other angles besides purely from the front.
    - The secondary light source can be used as an interactive part of the device reacting according to the environment.
    - The lighting device according to the present invention when the device is used in multi-unit configurations (eg a large scale matrix) the main light source can be switched off or dimmed, then the device changes, ceasing to be an automated air beam to become a graphic pixel with a bright, non-glare surface. Adequate effect-generating controls (eg media servers) are then able to display video content or simple color waves / patterns in the complete luminaire configuration.
    - The user will be able to run two individual light streams or media content on the same device.
