    Field of Invention
    [0001] The present invention relates to a lighting device comprising a number of light sources and a number of light collecting means organized in a housing. A number of light collecting means collect light from at least one of the light sources and convert the collected light into a series of source light beams. The light source beams are emitted from said housing. Fundamentals of the Invention
    [0002] Lighting fixtures creating various effects are being used more and more in the entertainment industry, with the purpose of creating various lighting and ambient lighting effects in relation to live shows, TV shows, sporting events or as a part of the installation architectural.
    [0003] Entertainment luminaires usually create a light beam, having a beam width and a divergence and may be, for example, reflector type luminaires, creating a relatively wide light beam with a uniform light distribution or they may be luminaires profiles adapted to project the image onto a target surface. There is a trend that more and more this type of luminaires is used in every show or every installation and the luminaires get as a consequence more and more visible to the sectors or TV viewers. Fixtures usually create a lighting effect at a distance from the lighting fixture itself and the fixture is therefore not as interesting and aesthetic to look at. The luminaire factories consequently try to provide the luminaires with aesthetic designs in order to make the luminaires more interesting to look at. However, this is very difficult when the housing of normal luminaires depends on physical requirements defined by the technical descriptive reports of the luminaire such as optical, mechanical, electronic, cooling, etc.
    [0004] The LED component has additionally as a light source altered the appearance of most lighting fixtures when using multiple LEDs to replace a single light source. This implies all lighting industries - general, domestic, industrial, entertainment and so on. The most visible change is that all the various light sources are now exposed to the viewer and light is emitted over a larger area. Now that most LED lighting fixtures have visible LEDs, some customers don't like the appearance of multiple points of light. The dotted "Amusement Park" appearance appears both in fixtures that mix colors before light is emitted from the housing and fixtures where colors are mixed in the air or on the wall. Instead, a more uniform one, even if light output is required, to avoid the economical appearance of the Amusement Park appearance with a large amount of light sources. Description of the Invention
    [0005] The purpose of the present invention is to solve the limitations described above, related to the state of the art. The advantages and benefits of the present invention are described in the detailed description of the invention. Description of Drawings

    [00013] The present invention is described in view of a movable head luminaire including a number of LEDs that generate a light beam, however the person skilled in the art will realize that the present invention relates to lighting devices using any type of 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 embodiments are simplified and illustrate the principles of the present invention, rather than showing an exact embodiment. The person skilled in the art will therefore understand that the present invention can be incorporated in many different forms and also includes more components in addition to the components shown.
    [00014] Figures 1a to 1b illustrate a lighting device, according to the state of the art, in which figure 1a is a perspective view and figure 1b is an enlarged view. The lighting device is a movable head luminaire 101, comprising a base 103, a swivel yoke 105 connected to the base and a swivel head 107 connected to the yoke.
    [00015] 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 means collects light from light sources and converts the light collected in a number of beams from the light source 113 (only one illustrated), which are emitted from the housing.
    [00016] In the illustrated mode the head housing 107 is a "plunger" in the head housing 111 format in which a display 115 (visible from the rear of the head), main PCB 117 (Printed Circuit Board), a fan 119, a heatsink 121, an LED PCB 123, and a set of lenses are stacked. The lens assembly comprises a lens holder 125 and an array of lenses comprising the light collecting means 109. The head is rotatable connected to the yoke by two tilt bearings 127 and which are supported by the 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 yoke housing parts 132 which are mounted on a yoke structure 134 where on the tilt bearings, motor tilt, pan motor and pan bearing are arranged. The LED PCB 123 comprises a number of LEDs which emit light and which in cooperation with the light collecting means 109 in the lens array generate a number of light source beams. The main PCB comprises controlling circuitry and driving circuitry (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 extend through a series of holes in the head housing 111. The switches and display act as a user interface, allowing a user to communicate with the head light main mobile.
    [00017] The yoke is connected to a swiveling panning bearing 133 connected to a base 103. A panning motor 135 is adapted to rotate the yoke through a panning belt 137 connected to the panning bearing 133. The base comprises 5 pins XLR male 139 and female connectors 141 for DMX signals as known in the entertainment lighting art; input connectors 143 and output power 145, PCB power supply network (not shown) and fan (not shown). The fan forces air into the base through vent holes 147.
    [00018] This prior art lighting device uses multiple LEDs to replace a single light source as previously known for the introduction of LED component as a widely used light source. However, such a lighting device changes its visible appearance when the various light sources are now exposed to the viewer and the light is emitted over a larger area. If the lighting fixtures are a color mix version with single color LEDs, all LED colors used will be visible. However, some customers do not like the appearance of multiple points of light. Instead, a more uniform output, even if light is required, to avoid the economical appearance of the Amusement Park look with a large amount of light sources.
    [00019] The lighting device illustrated in figures 1a and 1b is just one example of obtaining prior art lighting and the person skilled in the art will realize that a large number of different modalities provided by a large number of factories come out.
    [00020] Figures 2a to d illustrate a simplified embodiment of a lighting device, according to the present invention. Figure 2a is a top view and Figure 2b is a top view with the light guide 213 and light collecting means 209 removed. Figure 2b and 2c are cross-sectional views along lines A-A and B-B respectively.
    [00021] The lighting device 201 comprises a number of light sources, arranged in at least a first group of light sources 203 (indicated as white squares) and in a second group of light sources 205 (indicated as black squares) . The light sources are mounted on a PCB 207 (printed circuit board) and two groups of light sources can be controlled individually, for example, by a controller (not shown) as known in the lighting art. The controller is thus adapted to treat the two groups of light sources as at least two individual light sources that can be individually controlled. However, the person skilled in the art will realize that the lighting device can also be adapted to divide each group of light sources into a number of subgroups that can also be individually controlled and that it is also possible to individually control each single light source. . A number of light collecting means 209 are arranged above and around the first group of light sources 203 and are adapted to collect light from the first group of light sources and convert the collected light into a series of light beams. source 211. The light collecting means 209 may be incorporated as any optical component capable of collecting light from light sources and converting the light into light beams, and may be, for example, optical lenses, light mixers, TIR lenses , etc. In the illustrated embodiment the light collecting means 209 are incorporated as TIR lenses, as known in the prior art, and one skilled in the art will realize that the TIR lens can be designed according to the light output of the light source and the properties light source beam optics 211. The light beams 211 will merge into one large beam of light as the distance to the lighting device increases.
    [00022] The light guide 213 is disposed above PCB 207 and the light guide 213 comprises an input section 217 and an output section 219. The light guide receives light from the second group of light sources 205 in the input section 217 and guides the received light to output section 219, which is adapted to emit received light to an area 218 between at least two of the source light beams 211. The light beams 211 will merge into one Large beam of light as the distance to the lighting devices increases. The area between at least two light source beams can be defined as all points viewed from above of the light source beams that lie in a straight line, which intercept at least a part of both light beams. It should be understood that many straight lines that intersect at least a part of both light beams and in the area between the two light source beams therefore constitute a surface. Furthermore, it should be understood that the area may physically lie below the light sources, as long as it appears to be between the light sources when viewed from above.
    [00023] The light guide 213 is embodied as a solid transparent material and the light rays from the insertion of an input section will be internally reflected to an output section in which the light rays are coupled out of the light guide. In this embodiment, the light guide 213 is shaped like a light guide disk comprising a number of apertures, in which the light collecting means is arranged and a series of protrusions 220 protruding backwards from the guide disk. of light. The protrusions are adapted to fit above the light sources 205 of the second group and the inlet sections are situated on the lower surface of the protrusions. The sections that make up the front exit area of the light guide disc. Light entering the input sections is first reflected internally through the protrusions and is then reflected off angular reflection surfaces 222 in a direction substantially along the plane of the disk.
    [00024] For example, as illustrated in figure 2c the light source 205a belonging to the second group of light sources emits a series of light rays (illustrated as thin filled lines). The light rays entering the light guide 213 at the input section 217A, where after experiencing the internal reflection inside the light guide and being guided to the outputs 219a, where the light rays are coupled out of the light guide. light 213. It should be understood that only a small number of light rays are illustrated within the light guide and that, in total, a large number of light beams will be emitted in a large number of instructions as indicated by the arrows 221. Similarly, light sources 205b that belong to the second group of light sources emit a series of light rays (illustrated as thin filled lines) that introduce light guide 213 into input section 217b and are coupled to off light guide 213 in output section 219b. Furthermore, in figure 2d the light sources 205c and 205d generate light beams that are emitted from output sections 219c and 219d, respectively. The result is that the areas between the light beams can be illuminated by the second group of light sources 205 and the dotted appearance of prior art luminaires can be avoided.
    [00025] Output sections 219 are adapted to couple the light rays away from the light guide. This can, for example, be achieved by adjusting the surface roughness of the light guide at the output sections whereby the light rays do not experience a full internal reflection when they hit the rough surface and, as a consequence, the light is coupled. out of the light guide. Alternatively, the surface of the light guide 213 can be treated with a material that will propagate the light reaching the exit point. Another possibility is to tilt the lower and upper surfaces of the light guide relative to each other, which results from the fact that the angle of incidence of the light rays traveling inside the light guide changes. The output sections can be adapted to couple the light out of the light guide in a homogenized shape so that the entire front surface of the light guide disc appears as a homogeneous illuminating surface. This can, for example, be achieved by gradually modifying the roughness across the output sections in such a way that only a small part of the light is turned on from the output sections near the input sections, although most of the light is turned on. out of the light guide in areas farther away from the entry point. The light guide and external coupling, for example, can be constructed using techniques known in the art for backlighting television displays and/or mobile telephone displays. In the illustrated embodiment the light guide is in the form of a disc, however, it is to be understood that it is the light guide which can be of any shape.
    [00026] Figures 3a-3d illustrate another embodiment of a lighting device according to the present invention. Figure 3a is a top view and Figure 3b is a top view with the light guide 313 and light collecting means 209 removed. Figures 3c and 3d are cross-sectional views along lines CC and DD, respectively. Like the embodiment illustrated in Figures 2a to 2d the first group of light sources 203 (indicated as white squares) is arranged on a PCB 207 with the light collecting means 209 disposed above the light sources and a series of beams from the light source of light 211 is hereby created. In this embodiment, the light sources part of the second group 205 is mounted on the PCB 207 as in figures 2a to 2d. The light sources 205a and 205b emit a series of light rays (illustrated as thin filled lines) that introduce the light guide 313, respectively, into the input section 217a and 217b and is coupled out of the light guide 313 in sections. output 219a and 219b. However another part 305 of light sources from the second group is arranged circumferentially around the light guide 313 and mounted on a number of vertical PCBs 308 which are perpendicular to the PCB 207. The consequence is that the circumferential wall of the guide of light 313 can function as an input sector 317. As illustrated in figure 3d the source 305c and 305d emits a series of light rays (illustrated as thin filled lines) which introduce the light guide 313 respectively into the input section 317c and 317d and is coupled out of light guide 313 at output sections 319c and 319d. It should be understood that the inner ring of light sources can also be adapted to emit light directly to the light guide, for example by arranging these light sources around the center of the light collecting means and letting the light sources emit light outwards from the center of the light guide.
    [00027] Figure 4 illustrates a modality that is similar to the modality of figs. 3a to 3d, however, the light guide 413 has been modified in such a way that the output sections 417 have been arranged in a predetermined pattern and, thus, light will only come out of the light guide for these areas. The consequence is that the second 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, which can be observed by a viewer looking at the lighting device. . The light sources can be arranged so that light from one or a subgroup of light sources illuminates a specific output section and the lighting device can be adapted to control the individual subgroups. This makes it possible to control the different part of the optical pattern individually, eg turn on/off, the color change of certain parts of the predetermined pattern. The predetermined pattern can thus be used as a dynamic pattern, which can be used to create many of the interesting lighting effects. The predetermined pattern of the light guide 413 can, for example, be created to treat the upper surface of the light guide in the predetermined pattern so that only light is coupled out of the light guide to these areas while the internally reflecting light rays experience the other areas. It is also possible to achieve the same effect using a number of different light guides which act as individual light guides (for example as illustrated in figures 6a and 6b), rather than being integrated as a light guide disc.
    [00028] Figures 5a to 5e illustrate another embodiment of a lighting device according to the present invention. Figure 5a is a top view and Figure 5b is a top view with light guides 513, light collecting means 209 removed and scattering regions 512 removed. Figures 5c, 5d and 5e are cross-sectional views along lines E-E, F-F and G-G, respectively. Like the embodiment illustrated in Figures 3a to 3d the first group of light sources 203 (indicated as white squares) is mounted on a PCB 207 with the light collecting means 209 disposed above the light sources and a series of beams from the light source of light 211 is hereby created. As in Figures 3a to 3d one part of the second group light sources 205 (shown as black squares) is mounted on the PCB 207 while the other part 305 of the second group light sources is arranged in series with vertical PCBs 308 that are perpendicular with respect to PCB 207. A series of light guides 514 (illustrated in detailed figures 6a and 6b) comprising an inlet section and an outlet section is disposed above PCB 207. The light guides 514 are adapted to receive light of at least one of the light sources of the second group in the input section and to guide the received light to the output section 519, which is adapted to emit the received light to an area between at least two of the beams of the light source. light 211.
    [00029] In this mode, the lighting device comprises a third group of light sources 504 (shown as dashed squares) arranged on the printed circuit board 207 and a number of diffusion regions 512 arranged above the PCB 207 and between at least two beams of the light source. Diffusion regions 514 are adapted to receive light from at least one of the light sources in the third group of light sources and propagate the received light.
    [00030] As illustrated in figure 5c the light source 205a and 205b emits a series of light rays (illustrated as thin filled lines), which respectively enter 514a and 514b into the light guide at the input sections 517a and 517b and are turned on from light guide 514a and 514b into output sections 519a and 519b. As illustrated in figure 5d the source 305c and 305d emits a series of light rays (illustrated as thin filled lines) which respectively enter the light guide 514c and 514d at the input section 517c and 517d and are connected from guides of light in the output sections 519c and 519d. As illustrated in Figure 5e the light sources 504a-d will illuminate the diffusion regions 512a-d. Light from these light sources will propagate in many directions, as illustrated by arrows 516a-516d. The consequence is that the dotted appearance of a lighting device as known in the prior art can be avoided and the lighting device can simultaneously be used to create graphic light effects by controlling the second group of light sources.
    [00031] The diffusion regions can, for example, be realized as a single solid body of a transparent material, which is adapted to propagate the light that hits the solid body. For example, molding the solid body into the clear polymer and treating the surfaces so that they propagate light. The solid body can be shrunk with a number of holes that were in the light collecting means 209 and light guides 514 can be provided.
    [00032] Figures 6a and 6b, respectively, illustrate the two types of light guides used in figures 5a-5e. The light guide in Figure 6a corresponds to light guides 514 (eg 514c and 514d of Figures 5a-e) which are adapted to lightly receive light sources 305 circumferentially disposed around the PCB 207. light is constructed from a transparent rod 601 comprising an inlet section 602 and an outlet section 603. The outlet section constitutes a surface of the rod and has been treated in such a way that light will be turned on from this surface, as illustrated by arrows 605. In this embodiment light source 305 is a 4 in 1 LED light source which comprises a red matrix R, green matrix G, blue matrix B and white matrix W and can thus create a large amount of color different from color using mixing additive. The light rod also assists in mixing colors from the 4 LED arrays. The light guide in figure 6b corresponds to light guides 514 (eg 514a and 514b of figures 5a-e) which are adapted to lightly receive the light sources 205 on the PCB 207. This light guide comprises a curve 606 which is adapted to reflect light from the inlet section to the outlet section 603.
    [00033] Figure 7 illustrates a block diagram of the lighting device according to the present invention. The lighting device comprises a control unit 701 comprising a processor 703 and a memory 705. The first group of light sources 203 and the second group of light sources 205 are connected to the control unit 701 and arranged in accordance herewith. invention. The processor acts as a control means and is adapted to control the first group 203 of light sources and the second group 205 of light sources individually. That is, the processing medium 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 intensity of light sources and can be based on any type of communication signals known in the lighting art, eg PWM, AM, FM, binary signals , etc. The first 203 and second 205 groups of the light source array can therefore be controlled individually and independently of each other, therefore they can be treated as two groups of light sources individually and independently. It should be understood that the individual light sources in each group are controlled by the same control signal, provided with individual control signals and/or grouped into subgroups where each subgroup receives the same control signal.
    [00034] In one embodiment the control means is adapted to control said first group of light sources based on an input signal indicative of a first target color of said first group of light sources. The input signal 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 per ANSI E1.11 and ANSI E1.20 standards, or Wireless DMX. ACN stands for Control Network Architecture; ANSI E1.17 - 2006).
    [00035] The input signal can, for example, be indicative of a first target color which can be any parameter that defines the color of light that the light sources of the first group should generate, for example, RGB values, color coordinates on 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 whereby the second group of light sources can be adapted and generate substantially the same color as the generated color. 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 such that the color of the second group of light sources is different, but aesthetically similar, 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.
    [00036] The person skilled in the art realizes that the lighting device also comprises a third group 504 of light sources as illustrated in connection with figures 5a to 5e. This group can be controlled in similar ways as the other two groups of light sources.
    [00037] The second and third group of light sources can function as backlighting with the DMX control itself, and the color and intensity can vary independently of the first group of light sources. They can also be linked in intensity and color with the LED primary color by default, or have separate control for contrast colors or other intensity. This adjustment/control of the light sources can be done remotely, from the central control unit, or from the device itself. The consequence is that a new light effect can be created, as the area between the light beams can 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 controlled independently, as known in the art of entertainment lighting.
    [00038] It is noted that: - The invention applies to multichip LEDs and single color LEDs. - 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 multiple LED lenses exposed to the viewer. - The second group of light source can be used as a new add-on effect feature on the device and acts as an eye-catcher, but more importantly as an individual pixel when used in multi-unit configurations. In this way, it is a beam of air and an illuminated surface. - The second group of light source can also be used to indicate errors or other device status information. - The invention creates a possibility to make light/color visible from other angles than 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 array) the main light source can be turned off or dimmed, then the device switches, no longer be an automated air beam to become a graphic pixel with a non-glare glossy surface. Appropriate effect generator controls (eg media servers) are then able to display video content or simple color waves/patterns in the full fixture configuration.
    [00039] User will be able to play two individual light sequences or media content on the same device.
    [00040] A content generated by the first group of light sources and other content generated by the second group of light sources.
    [00041] Which error messages or device status can be communicated through colors, color combinations, flashes, or other effects through the secondary light source.
    [00042] That through an internal or external sensing/monitoring technology, the secondary light source can act according to a predefined reaction pattern (color, intensity or intermittent). Input can be the behavior of a person, the light level in the room, changes in temperature, humidity, etc.)
