  Hereinafter, embodiments of the illumination device of the present invention will be described.

  The present embodiment is an embodiment in which the lighting device of the present invention is installed in a living room where a video device composed of a thin large-screen television is installed, and the configuration thereof will be described with reference to FIGS.

  Reference numeral 10 denotes an illuminating device according to the present invention, which includes an appliance main body 11 provided with a light source for illuminating the interior of the living room, detection means 12 installed in the appliance main body, and illumination control data generated based on signals from the detection means, and illumination control. It is comprised by the control part 13 which carries out light control of the light source of an instrument main body according to data.

 Reference numeral 20 denotes a video device installed on the wall surface in the back of the living room, and reference numeral 21 denotes an audio device composed of a 5.1CH surround system installed on both sides of the video device.

 The appliance main body 11 is composed of a circular ceiling appliance for residential use installed in a substantially central portion of the ceiling of the living room. The fixture main body 11 is installed in the central portion of the annular light source 11a and the annular fluorescent lamp, and turns on the light source. And a cover 11c made of milky white translucent synthetic resin that covers the light source from below.

Since the appliance main body 11 configured as described above is installed at a substantially central portion of the ceiling X of the living room so that the entire room can be looked over, the entire room can be illuminated to every corner. (Figure 2)
The detecting means 12 detects the operating state of the video device based on the luminance distribution in the room, and is composed of a wide-angle type image sensor composed of a CCD. It is installed so as to be exposed downward from the center of 11c.

 As a result, the detection zone of the wide-angle type image sensor is installed so as to substantially overlap the illumination range of the light source 11a so that the entire room can be seen from every corner, and the state of the entire room can be monitored constantly.

 In this embodiment, as a wide-angle type image sensor, a CCD of about 70,000 to 300,000 pixels, preferably about 320 × 240 (less than about 80,000 pixels), which is advantageous in terms of cost and easy to process signals, is used. Use.

 In this embodiment, since the signal obtained from the CCD is processed as a moving image, a high-pixel CCD is not suitable because the amount of information increases and the processing becomes heavy.

 The control unit 13 includes a calculation unit that generates illumination control data based on a signal from the detection unit 12, and a control unit that performs dimming control of the light source 11a according to the illumination control data of the calculation unit, and includes a microcomputer or the like. It is composed of an electronic circuit and is integrated into a case that houses the lighting device 11b.

  The lighting device 10 having the above configuration is dimmed and controlled by the control unit 13 and can be manually turned on / off by a switch installed on a wall surface of the room, and a switch for selecting a crime prevention mode is provided on the wall surface switch. Installed side by side.

  Next, the operation of the illumination device 10 configured and installed as described above will be described.

  At night, the lighting device is usually turned on to appreciate the video device 20. In this case, the entire room is illuminated brightly, and eyestrain is less likely to occur even when viewing the video device.

 Next, in order to enjoy movies and the like at night in the theater mode, when the lighting device 10 is turned off and the interior of the room is viewed in darkness for the purpose of enhancing the atmosphere and presence, the lighting device is dimmed and darkened. It automatically changes from dark to dim, reducing the change in room brightness and reducing eye fatigue.

That is, the detection means 12 installed in the illumination device 10 constantly monitors the room, and the detection means has a low gradation value of the entire image when the illumination is turned off and the room is dark, but the video device is installed. When only the gradation value of the portion A is high and there is always a change in RGB gradation values, and the amount of change is large, it is determined that the video device is being viewed in a dark room, and the operating state of the video device is That is, it is determined that the video apparatus is operating in a dark room. (Figure 3)
As a result, the detection means 12 transmits a signal indicating that the video device 20 has been operated in a dark room to the calculation unit, and the calculation unit generates illumination control data for gradually dimming and lighting based on the signal to generate the control unit 13. Transmit to.

  The control unit 13 gradually dims the light source 11a of the lighting device 10 in accordance with the lighting control data, and the brightness until the room becomes dim without knowing not to destroy the atmosphere of the viewing environment. Make sure the lighting is secure.

  As a result, the viewer can watch from a dark state to a dim state, and the change in brightness can be reduced to reduce eye fatigue.

 Note that even when the detection unit 12 illuminates the lighting device 10 in a dim state, a bright portion A is locally generated in the room by the operating video device 20, and the brightness and color also vary. The lighting device continues to be lit in a dim state by detecting that the video device is operating.

  Further, when the switch of the video device 20 is turned off, it is determined that there is no change in the RGB gradation values of the portion where the video device is installed and the gradation value of the entire room is low, and the dimming lighting is stopped and the lighting device 10 is stopped. Is turned off. Or it is set as the state of 100% continuous light control lighting.

 Next, when the lighting device 10 is turned on in the daytime or nighttime and the video device 20 is viewed in a bright room, there are changes in the RGB gradation values of the portion where the video device is installed, and the amount of change is large. The gradation value of the entire room is also high, and the lighting apparatus 10 is turned on or daylight enters the room, and the entire room is judged to be bright, and the lighting apparatus is not dimmed.

  Next, when appreciating the video device 20 from the daytime, and the surroundings darken without knowing it, the gradation value of the entire image excluding the screen of the video device 20 gradually decreases. When it falls below a certain threshold, dimming lighting is automatically started. At this time, the threshold value of the gradation value is always kept by increasing the dimming rate in accordance with the speed at which the gradation value decreases.

 Thereby, as the brightness of the room becomes darker, the light source 11a of the lighting device 10 gradually starts dimming in the same manner as described above, and the room can be kept in a certain level of brightness without a sense of incongruity. At the same time, by always keeping the threshold value of the gradation value, it is not dark, but the viewer can automatically watch in the dim state, and can reduce eye fatigue.

  Next, when the crime prevention mode is set, the detection means 12 always monitors the indoor state regardless of the operating state of the video device 20, and automatically turns on the dimming when the surroundings become dark due to sunset. First, the lighting device 10 can be turned on, and the presence of the room can be assumed.

 In the case of the security mode, for energy saving, for example, it is set to be lit at a brightness of about 50% dimming rate (note that the dimming rate in the security mode may be 100% continuous dimming, A configuration capable of setting an arbitrary dimming rate is preferable).

 Moreover, it can set so that the illuminating device 10 may be automatically extinguished at an arbitrary time of the night. In this case, even if the setting for turning off the light is forgotten, the detection means 12 always monitors the indoor state and automatically turns off when the room becomes brighter by daylight at dawn. In addition, the dimming rate can be gradually lowered to darken according to the accumulated lighting time.

 As described above, according to the present embodiment, even if the lighting device 10 is turned off and the room is completely dark and the video device 20 is viewed, the lighting device automatically changes from a dark state to a dim state, and the brightness of the room is reduced. It is possible to reduce the change and reduce eye fatigue.

 Moreover, since the control part 13 light-controls and lightens the light source 11a of the illuminating device 10 gradually, it can avoid destroying the atmosphere of viewing environment.

 Even when the video device 20 continues to be appreciated from daytime and the surroundings become dark due to the sunset, the light source 11a of the lighting device 10 gradually starts dimming and maintains a certain level of brightness in the room without a sense of incongruity Can be.

 In addition, by always keeping the threshold value of the gradation value, it does not become a dark state, and the viewer can automatically view in a dim state and can reduce eye fatigue.

 Furthermore, since the detection means 12 is composed of a wide-angle type image sensor composed of a CCD and is installed in the illumination device 10 that can illuminate the entire room to every corner, the sensor can be placed at a perfect position overlooking the entire room. The operation state can be reliably detected with respect to the state of the video device 20 installed in various ways, and the light control of the lighting device 10 can be reliably performed.

 Further, the detection means 12 is composed of an image sensor composed of a CCD and detects the operating state of the video device 20 based on the indoor luminance distribution, so that it is exposed downward from the center of the cover 11c of the illumination device 10. Thus, dimming control can be performed with a simple configuration that is simply installed.

 In addition, since no wiring connection for transmitting a signal between the lighting device 10 and the video device 20 is required, it can be installed in an existing lighting fixture.

 In addition, by setting the crime prevention mode, when the surroundings become dark due to nightfall, the dimming lighting can be started automatically and the lighting device can be turned on, and it is possible to have a crime prevention effect that pretends to be in the room. . Moreover, even if the setting for turning off the light is forgotten, the light can be turned off automatically.

 Further, in the present embodiment, a configuration may be adopted in which a variable color lighting fixture is used for the lighting device 10 and a change in the color temperature of the screen of the video device 20 is detected by a CCD.

 For example, when the detection unit 12 detects the operation of the video device 20 in a dark room, the control unit 13 automatically enters the theater mode and controls to change the light color of the lighting device 10 according to the screen change of the video device 20. May be performed.

 As described above, in this embodiment, the detection unit 12 is installed so as to be exposed downward from the center of the cover 11c of the illumination device 10, and the detection zone of the image sensor is substantially overlapped with the illumination range of the light source 11a. As shown in FIG. 4, a plurality of image sensors 12a are provided around the illumination device 10, and the detection zone of the image sensor is set to be wider than the illumination range of the light source, so that the operating state of the video device can be detected more reliably. You may do it.

 Although the control part 13 was integrated and comprised in the case which accommodates the lighting device 11b of the illuminating device 10, it comprised separately from a point etc. apparatus, and the switch which selects a manual lighting on / off switch and crime prevention mode was comprised. It may be installed on the wall of the room.

 Further, a sound sensor (microphone) may be further installed in the fixture body 11 of the lighting device 10 to detect the sound pressure level generated from the video device 20.

 As a result, the sound pressure level increases. For example, the light source 11a of the lighting device 10 is automatically turned on and off in accordance with a scene where “thunder is thundering”, and the light is dimmed so that it flashes instantaneously, and it is not dark Even in a room that is dimly lit and lit by means 12, it is possible to perform appreciation with a more realistic feeling.

 Further, in combination with voice recognition technology, voice control, for example, control may be performed so that the illumination is turned on when “bright” is mentioned, or the illumination is dimmed when “dimming” is mentioned.

 In this embodiment, the lighting device of the first embodiment, in other words, the lighting device installed at a position where the entire room can be looked over, is provided with a detecting means for detecting the video data of the video device from the screen. The light source for indoor lighting is dimmed based on the signal from the light source to reduce eye fatigue, and the light emission pattern of the image light source unit is controlled to improve the presence of the image device. The configuration will be described with reference to FIGS.

 5 to 6, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, the illumination device 30 of the present embodiment includes an appliance main body 11 having a light source 11 a for indoor illumination, an image light source unit 40 that illuminates a peripheral portion of the imaging device, and an indoor luminance installed in the appliance main body. Based on the distribution, the operating state of the video device is detected, and the video data of the video device is detected by a change in at least one of the brightness and light color of the screen, and the illumination control data is obtained based on a signal from the detection unit. The light source 11a of the instrument main body 11 is dimmed and controlled according to the illumination control data, and the control unit 60 controls the light emission pattern of the video light source unit 40.

  The image light source section 40 in this embodiment illuminates the peripheral portion of the image apparatus 20, and is installed one by one with a space on both sides of the image apparatus 20, as shown in FIG.

 As shown in FIG. 6, the video light source unit 40 includes a first light source unit 41 that illuminates the background of the video device 20 and a second light source unit 42 that illuminates the viewing-side surface. Illuminate.

 The first light source unit 41 is configured by vertically arranging three straight tube fluorescent lamps 41a of RGB single colors which are the three primary colors of light, and the rear surface of the first light source unit 41, that is, the viewing side surface. The second light source unit 42 is provided.

 The 2nd light source part 42 is comprised as a planar light source by which organic EL42a is comprised as a light source and the whole opening shines.

 Said 1st, 2nd light source parts 41 and 42 are wiring-connected by the lighting apparatus 11b and the control part 60 of the instrument main body 11 with a cable.

 The detection means 50 in this embodiment is constituted by a wide-angle camera using a CCD having about tens of thousands to two million pixels, for example. Further, it is desirable that the image data is processed after, for example, an image shot at 320 × 240 (76800 pixels) is reduced to a low pixel such as 160 × 120 or 80 × 60.

 The control unit 60 reduces the number of pixels of the video data from the detection unit 50 configured by the camera, generates illumination control data based on the video data, and according to the illumination control data, the light source 11a of the instrument main body 11. Is controlled, and the light emission pattern of the image light source unit 40 is controlled.

 Next, the operation of the illumination device 30 configured and installed as described above will be described.

 First, the detection means 50 comprising a camera installed in the illumination device 30 constantly monitors the room, and as in the first embodiment, the detection means 50 performs gradation of the entire image with the illumination turned off and the room dark. Although the value is low, only the gradation value of the portion where the video apparatus 20 is installed is high, and there is always a change in the RGB gradation values, and when the change amount is large, the video apparatus 20 is viewed in a dark room. It is determined that the image device is in an operating state, that is, the image device is operating in a dark room, and the lighting device 10 is turned off and automatically changed from a dark state to a dim state to adjust the brightness of the room. Reduce changes to reduce eye strain.

 In the same manner as in the first embodiment, the dimming control of the light source 11a for indoor lighting when the surroundings become dark while watching the video apparatus from the daytime, and the dimming control of the light source 11a in the crime prevention mode is performed. Perform light control.

 Note that the detection means 50 in the present embodiment may perform light control more reliably by using a camera composed of a CCD having a large number of pixels.

  In the present embodiment, the camera that is the detection means at the same time as the dimming control of the light source 11a for room lighting, the change information of at least one of the luminance and light color on both sides of the screen of the video device 20, in this embodiment The video data of the image is detected based on the color information, illumination control data is generated based on the video data from the detection means, and the light emission pattern of the video light source unit 40 is controlled.

 That is, the two image light source units 40 configured as described above are provided on the both sides of the image device 20 with one straight tube fluorescent lamp 41a constituting the first light source unit 41 at a predetermined interval. It is installed so as to be vertical and illuminate the back side of the video apparatus 20, and is installed so that the second light source unit 42 faces the viewing side.

The video light source unit 40 installed above operates as follows.
The camera which is the detection means 50 detects the video data of the image based on the luminance and color information on both sides of the screen of the video device 20, and transmits this video data to the calculation unit of the control unit 60.

 As a result, the calculation unit analyzes the RGB signal and the luminance signal for each pixel of the screen of the video device 20, performs calculation processing from the analysis result, and generates illumination data relating to the average chromaticity and average luminance of the entire screen. A signal composed of data is output to the first light source unit 41.

  Thereby, the wall surface Y on the back surface of the video device 20 is illuminated by the first light source unit 41 with an irradiation surface larger than the screen, for example, with a light emission pattern that emits blue light if the screen is blue, and the blue sky of the screen Is continuously spread around the screen, and illumination with a sense of presence with a sense of spread as a whole can be performed.

  At the same time, the calculation unit analyzes the RGB signal for each pixel of the screen, and outputs a blue signal to the second light source unit 42 if, for example, the screen is blue.

  As a result, the organic EL 42a that forms the planar light source of the second light source unit 42 lights up with a light emission pattern that emits blue light having a brightness approximate to the blue sky of the screen projected on the screen, and becomes blue toward the viewing side. In harmony with the blue illumination of the background by the first light source unit 41, the blue sky of the screen smoothly and surely continuously spreads around the screen, and the illumination with a sense of presence as a whole is spread. It can be carried out.

 As described above, the video light source unit 40 is controlled with various light emission patterns based on the video data from the detection means 50 including a camera, and the illumination is linked to the video of the video device to improve the sense of reality. it can.

 As described above, according to the present embodiment, as in the first embodiment, the change in the indoor brightness can be reduced, and the eye fatigue can be reduced. At the same time, the video data of the video device 20 is read from the screen. The illumination device 30 capable of giving the video device a sense of realism can be provided by the detection means 50 including a camera for detection.

 In particular, the video light source unit 40 can approximate the brightness and color of the wall Y on the back of the video device 20 to the screen, so that the change in brightness at the periphery of the video device becomes smaller, and the realism is improved. Eye fatigue can be further reduced.

 In addition, since the detection means 50 for detecting video data from the screen is installed in the instrument main body 11 having the light source 11a for room illumination, it is possible to monitor the entire room and install it in various ways. The video data can be reliably detected with respect to the screen state of the video device 20.

 In addition, this kind of lighting system aiming at improving the sense of presence is, as shown in Patent Documents 1, 2, 3, etc., fetching video data from video playback devices such as TV tuners, video tape recorders, DVD players, etc. However, for example, in the case of a general television, the video output terminal is not provided, and illumination linked to the video cannot be performed.

 In particular, in the future, when the age of multi-channels such as BS, CS, etc. will be reached and various video and games can be enjoyed without installing a video playback device, video devices such as televisions have video terminals etc. Video devices without output terminals will appear.

 In such a case, the lighting device 30 of the present embodiment does not need to capture video data from the output terminal of the video device, and therefore can provide a lighting device with sufficient versatility and excellent versatility.

 In particular, illumination linked to the video can be performed not only on the video by the video playback device but also on the video of the television broadcast itself.

 Furthermore, in order to cope with the times as described above, it is conceivable to use a sensor that directly targets the television screen. For example, aiming at the screen from the TV frame or aiming at the screen from a location slightly away from the TV, both of which affect the viewing environment, such as being in the way of watching TV or anxious. there is a possibility.

 Even in such a case, since the illumination device 30 of the present embodiment has the detection means 50 installed in the instrument main body 11 having the light source 11a for room illumination, the upper position greatly deviated from the line of sight of the person or the angle of view. Therefore, it is possible to detect without disturbing the viewing of the video apparatus 20, and the viewing environment is not deteriorated.

  As described above, in the present embodiment, the sensor function for dimming control of the light source 11a for indoor illumination and the function for detecting video data are detected by one camera as the detection means. However, the light source 11a for illumination is used. As in the first embodiment, the dimming control sensor uses a CCD or pyroelectric sensor with a small number of pixels, which is advantageous in terms of cost, as a dedicated sensor for dimming control, and is separate from the sensor that detects video data. You may make up your body.
