  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A light environment control system shown as an embodiment of the present invention includes, for example, a lighting device 1 and a plurality of electronic devices 2 and 3 (hereinafter simply referred to as “electronic device” when collectively referred to) in a predetermined space 100 as shown in FIG. Control light in space 100. The light contained in the space 100 includes illumination light L emitted from the lighting fixture 1, screen light emitted from the electronic device 2, and screen light emitted from the electronic device 3.

  In the example of the light environment control system illustrated in FIG. 1, a portable terminal is illustrated as the electronic device 2, and a television is illustrated as the electronic device 3. The electronic devices 2 and 3 should just have the light emission parts 21 and 31 which the user P observes. The light emitting units 21 and 31 are screens for displaying images, for example. In the present embodiment, a case where the user P is observing the light emitting unit 21 that is a screen of a portable terminal as the electronic device 2 will be described.

  Moreover, the light environment control system has shown the ceiling light provided in the ceiling as the lighting fixture 1. FIG. The luminaire 1 is not limited to the ceiling light, and may be any that exists in the predetermined space 100.

  The lighting fixture 1, the electronic device 2, and the electronic device 3 in the light environment control system have a functional configuration as shown in FIG. In the present embodiment, the electronic device 2 and the electronic device 3 each have the same function.

  The luminaire 1 includes a lighting unit 11, a lighting control unit 12, an electronic device detection unit 13, a device setting unit 14, and a signal transmission / reception unit 15. Moreover, the lighting fixture 1 may be equipped with the computer as a structure for implement | achieving the illumination control part 12, the electronic device detection part 13, and the apparatus setting part 14. FIG. The computer executes a program stored in the storage unit 1a in the lighting fixture 1 and performs processing as described later.

  The illumination unit 11 is a light source of the luminaire 1. The illumination unit 11 may be a fluorescent lamp, an LED, or the like. The illumination unit 11 performs dimming according to the control signal supplied from the illumination control unit 12.

  The illumination control unit 12 supplies a control signal to the illumination unit 11 to control dimming. The illumination control unit 12 may be connected to an operation switch (not shown), a remote controller, or the like. The illumination control unit 12 supplies a control signal to the illumination unit 11 based on illumination control information supplied from an operation switch, a remote controller, or the like. As this illumination control information, a dimming value having a value of 0% to 100% can be cited. The illumination control information may be on / off information and color temperature.

  The electronic device detection unit 13 detects whether or not an electronic device that is an observation target of the user P exists in the space 100 (device detection means). The electronic device detection unit 13 includes, for example, a thermal sensor, a camera, a light emitter, and a receiver corresponding thereto. The electronic device detection unit 13 detects the presence / absence of the user P and the presence / absence of the electronic device.

  The electronic device detection unit 13 detects the electronic device that the detected user P is observing. For example, when the distance between the user P and the light emitting electronic device is short, the electronic device detection unit 13 detects that the light emitting electronic device is being observed. The electronic device detection unit 13 observes the light emitting electronic device when there is no electronic device emitting light in the vicinity of the user P and the electronic device located several meters away is emitting light. Is detected. Furthermore, the electronic device detection unit 13 may detect the electronic device that the user P is observing from the relationship between the face direction of the user P and the light emitting portion of the electronic device.

  In the situation illustrated in FIG. 1, the user P holds the electronic device 2 as a mobile terminal and observes the light emitting unit 21 that is a screen of the electronic device 2. This situation is detected by the electronic device detection unit 13. Further, the electronic device 3 that is not observed by the user P exists in the space 100 but is not detected as an electronic device that the user P observes.

  When the electronic device detection unit 13 detects that an electronic device is present, the device setting unit 14 sets a subordinate relationship between the detected electronic device and the lighting fixture 1 (subordinate setting unit). This dependency relationship is a relationship (parent-child relationship) in which electronic devices are controlled according to the lighting fixture 1. In the situation shown in FIG. 1, the lighting fixture 1 becomes a parent device (main), and the electronic device 2 becomes a child device (secondary). Although the electronic device 3 emits light, the user P does not observe it. Accordingly, the electronic device 3 is not set as a slave unit.

  The signal transmission / reception unit 15 exchanges signals with electronic devices. The signal transmission / reception unit 15 may communicate with the electronic device via a wired cable, or may communicate with the electronic device by wireless radio waves. Thereby, the signal transmission / reception part 15 transmits illumination control information to the electronic device 2 set to the subunit | mobile_unit by the apparatus setting part 14. FIG.

  The electronic devices 2 and 3 include light emitting units 21 and 31, signal transmission / reception units 22 and 32, and light emission control units 23 and 33. The electronic devices 2 and 3 may include a computer as a configuration for realizing the light emission control units 23 and 33. This computer executes programs stored in the storage units 2a and 3a in the electronic devices 2 and 3 to perform processing as described later.

  The light emitting unit 21 includes a light source built in the electronic device. In this embodiment, the light emission part 21 of the electronic device 2 is a display screen in a portable terminal. The light emitting unit 31 of the electronic device 3 is a television screen. The light emitting units 21 and 31 adjust the brightness according to control signals from the light emission control units 23 and 33. The light emitting units 21 and 31 may be capable of changing the color temperature or the like according to the color temperature of the lighting fixture 1 as well as the brightness.

  The signal transmission / reception units 22 and 32 receive the lighting control information transmitted from the lighting fixture 1. The received illumination control information is supplied to the light emission control unit 23.

  The signal transmission / reception units 22 and 32 may receive information on whether or not the signal transmission / reception units 22 and 32 are slave units for the lighting apparatus 1. When the self is a child device of the lighting fixture 1, the signal transmission / reception units 22 and 32 supply the lighting control information received from the lighting fixture 1 to the light emission control unit 23. When the self is not a child device of the lighting fixture 1, the signal transmission / reception units 22 and 32 discard the lighting control information received from the lighting fixture 1.

  The light emission control units 23 and 33 control the light emission states of the light emission units 21 and 31 based on the illumination control information received by the signal transmission / reception units 22 and 32. For example, when the illumination control information is the light control value (light control command) of the lighting fixture 1, the brightness of the light emitting units 21 and 31 is adjusted so that the brightness corresponds to the light control value.

  The light emission control units 23 and 33 may hold table data representing the brightness of the light emission units 21 and 31 with respect to the dimming value of the lighting fixture 1. In this table data, the desired brightness (light emission value) [%] of the light emitting units 21 and 31 in the space 100 is registered in advance for the dimming value adjustable by the lighting fixture 1. Thereby, the light emission control parts 23 and 33 can control the light emission parts 21 and 31 so that it may become the brightness memorize | stored in table data, when the light control value as illumination control information is acquired.

  Note that the electronic device may include a device detection unit subordinate to the lighting fixture 1. Similarly to the electronic device detection unit 13, the device detection unit in the electronic device may detect that the user P is observing his / her light emitting unit 21 with a camera. When the electronic device detects that the light emitting unit 21 is observed, the electronic device sets itself as a child device of the lighting fixture 1. Thereby, the electronic device can receive the lighting control information transmitted from the lighting fixture 1 and control the light emitting unit 21.

  The light environment control system configured as described above operates as shown in FIG. 3, for example.

  First, in step S1, the lighting control unit 12 in the lighting fixture 1 determines whether or not lighting control information has been generated. When the illumination control information is generated, the process proceeds to step S2.

  In step S2, the illumination control unit 12 controls the illumination unit 11 according to the illumination control information.

  In step S <b> 3, the electronic device detection unit 13 determines whether an electronic device as an observation target of the user P exists in the space 100. When there is no electronic device as an observation target of the user P, the light emission state by the other electronic device is maintained as it is (step S4).

  When the electronic device 2 as the observation target of the user P exists, the process proceeds to step S5. In step S5, the device setting unit 14 sets the luminaire 1 as a parent device and the electronic device 2 as a child device, thereby setting a subordinate relationship.

  In the next step S <b> 6, the signal transmission / reception unit 15 transmits illumination control information to the electronic device 2.

  In the next step S <b> 7, the signal transmission / reception unit 22 receives the lighting control information transmitted from the lighting fixture 1. And the light emission control part 23 controls the light emission state of the light emission part 21 according to illumination control information.

  According to such a light environment control system, the illumination control information is transmitted to the electronic device 2 when the illumination control information is generated. In response to this, the electronic device 2 controls the light emitting unit 21 according to the illumination control information. Thereby, according to a light environment control system, even if it is a case where the brightness around the user P changes with operation | movement of the lighting fixture 1, the discomfort given to the user who is looking at the screen of the electronic device 2 can be suppressed.

  For example, as shown to Fig.4 (a), suppose that the light control value of the lighting fixture 1 in the space 100 is 100%. At this time, the electronic device to be observed by the user P is the electronic device 2, and the electronic device 2 is set as a slave unit.

  In the state of FIG. 4A, it is assumed that lighting control information for changing the dimming value of the lighting fixture 1 to 70% is generated. In this case, as illustrated in FIG. 4B, the luminaire 1 transmits illumination control information indicating that the dimming value of the illumination unit 11 is 70% to the electronic device 2. Thereby, the light environment control system can control the brightness (light emission value) of the electronic device 2 to be lowered in response to changing the dimming value of the lighting fixture 1 to 70%.

  Therefore, according to this light environment control system, even when the ambient brightness changes due to the control of the illumination unit 11, it is possible to suppress a sense of discomfort given to the user who is viewing the screen. For example, the electronic device 2 includes an illuminance sensor, and the light emission state of the light emitting unit 21 can be controlled in a shorter time than when the light emission state of the light emitting unit 21 is controlled according to the detection value of the illuminance sensor. Thereby, the discomfort given to the user P when adjusting the brightness in the light emitting unit 21 of the electronic device 2 according to the illumination unit 11 can be suppressed.

  For example, as illustrated in FIG. 5, in response to the occurrence of a dimming command included in the lighting control information for the luminaire 1 (step S <b> 11), the luminaire 1 transmits a dimming value to the electronic device 2. Then, the lighting fixture 1 performs light control by the illumination part 11 (step S12). At substantially the same time, the electronic device 2 performs light emission control by the light emitting unit 21. Thereby, according to a light environment control system, light emission control can be performed according to light control.

  More specifically, the light environment control system may control the lighting unit 11 in the lighting fixture 1 as shown in FIG. 6 or FIG.

  In the control example illustrated in FIG. 6, the dimming value of the illumination unit 11 is gradually changed. As illustrated in FIG. 6A, it is assumed that illumination control information for changing the dimming value to 70% is generated and acquired by the illumination control unit 12 at time t1. As shown in FIG. 6B, the illumination control unit 12 controls the dimming value from time t1 onward. At this time, the illumination control unit 12 changes the dimming value with a gentle gradient from time t1 to time t2.

  The lighting control information for changing the dimming value is supplied from the lighting fixture 1 to the electronic device 2 after time t1. As illustrated in FIG. 6C, the electronic device 2 reduces the light emission value of the light emitting unit 21 at time t <b> 2 after receiving the illumination control information in association with the dimming value being 70%. Change the brightness to 70%.

  According to such a light environment control system, the dimming value of the illumination unit 11 is changed with a gradient according to the illumination control information. Thereby, according to a light environment control system, when the brightness of the illumination part 11 is changed suddenly, the discomfort given to the user P when the brightness of the light emission part 21 cannot follow can be suppressed.

  As another specific control example, as shown in FIG. 7, the illumination control timing of the illumination unit 11 and the emission control timing of the light emitting unit 21 may be set substantially at the same time.

  As shown in FIG. 7A, it is assumed that illumination control information for changing the dimming value to 70% is generated and acquired by the illumination control unit 12 at time t1. As shown in FIG. 7B, the illumination control unit 12 stands by for control of the light control value until time t2.

  The lighting control information for changing the dimming value is supplied from the lighting fixture 1 to the electronic device 2 after time t1. As illustrated in FIG. 7C, the electronic device 2 reduces the light emission value of the light emitting unit 21 at time t <b> 2 after receiving the illumination control information in correspondence with the dimming value being 70%. .

  The light environment control system described above includes a lighting fixture (1) existing in a predetermined space (100), and an electronic device (2) having at least a light emitting section (21). This light environment control system has a device detection means (13), a subordinate setting means (14), and a control means (23). The device detection means detects whether or not an electronic device that is a user's observation target exists in the space. The subordinate setting unit sets a subordinate relationship for controlling the electronic device according to the lighting fixture when the device detecting unit detects the presence of the electronic device. When the dependency relationship is set by the dependency setting device, the control means transmits lighting control information for controlling the lighting fixtures to the electronic device for which the dependency relationship is set, and based on the lighting control information, the light emitting unit of the electronic device Control light emission.

  The light environment control program in this embodiment determines whether or not there is an electronic device (2) that is a user's observation target in a predetermined space (100) and has at least a light emitting unit (21). Device detecting means (13) for detecting, subordinate setting means for setting a subordinate relationship for controlling an electronic device according to a lighting device existing in a predetermined space when the presence of the electronic device is detected by the device detecting means ( 14) When the dependency relationship is set by the dependency setting means, the lighting control information for controlling the luminaire is transmitted to the electronic device for which the dependency relationship is set, and the light emission unit of the electronic device emits light based on the lighting control information. Functioning as control means (23) for controlling.

  According to such a light environment control system, the dimming control timing of the illumination unit 11 is matched with the light emission control timing of the light emitting unit 21. Thereby, the time difference that the brightness of the illumination unit 11 is adjusted first and then the brightness of the electronic device 2 is adjusted can be shortened. Thereby, according to the light environment control system, the discomfort given to the user P by changing the brightness of the illumination part 11 and the light emission part 21 can be suppressed.

  Next, as an embodiment of the above-described light environment control system, as shown in FIG. 8, an apparatus having an information providing unit (illumination control information providing unit) 10 that provides illumination control information to the luminaire 1 will be described.

  The information providing unit 10 includes, for example, a remote controller for a lighting fixture and a HEMS controller embedded in a wall of a room such as the space 100. This HEMS controller has a power control function, for example. For example, when the power is limited, the lighting control information of the lighting fixture 1 can be adjusted to control the power consumption of the lighting fixture 1. The information providing unit 10 communicates with the lighting fixture 1 through a wired or wireless network.

  The information providing unit 10 includes a signal transmission / reception unit 101, a dimming control unit 102, and an operation unit 103. The information providing unit 10 may include a computer as a configuration for realizing the dimming control unit 102. The computer executes the program stored in the storage unit 101 a in the information providing unit 10 to control the lighting fixture 1.

  The operation unit 103 includes a touch panel exposed from a wall, operation buttons, a dial, and the like. The operation unit 103 is operated when adjusting the brightness or the like of the lighting fixture 1. The operation performed by the operation unit 103 is read by the dimming control unit 102.

  The dimming control unit 102 reads an operation performed on the operation unit 103. The dimming control unit 102 generates lighting control information representing the dimming value of the lighting fixture 1 based on the read operation. This illumination control information is transmitted from the information providing unit 10 by the signal transmitting / receiving unit 101.

  This lighting control information is received by the lighting fixture 1 as a base unit of the electronic device 2. The lighting fixture 1 transmits the lighting control information to the electronic device 2 in response to receiving the lighting control information.

  The lighting control information transmitted from the lighting fixture 1 is received by the electronic device 2 as a slave unit. Thereby, the electronic device 2 controls the light emission of the light emitting unit 21 based on the illumination control information transmitted from the information providing unit 10 via the lighting fixture 1.

  For example, as illustrated in FIG. 9A, it is assumed that the dimming value of the lighting fixture 1 is 100% in a state where the lighting control information is transmitted from the information providing unit 10 to the lighting fixture 1. At this time, the electronic device to be observed by the user P is the electronic device 2, and the electronic device 2 is set as a slave unit.

  In the state of FIG. 9A, it is assumed that lighting control information for changing the dimming value of the lighting fixture 1 to 70% is generated in the information providing unit 10. In this case, as illustrated in FIG. 9B, the information providing unit 10 transmits to the lighting fixture 1 lighting control information indicating that the dimming value is 70%. The luminaire 1 transmits illumination control information for setting the dimming value to 70% to the electronic device 2. Thereby, the light environment control system can control the dimming value of the lighting fixture 1 to 70% and further control the emission value of the electronic device 2 to be low.

  For example, as illustrated in FIG. 10, the information providing unit 10 transmits a dimming value to the luminaire 1 in response to the occurrence of lighting control information in the information providing unit 10. Thereafter, the lighting fixture 1 transmits lighting control information to the electronic device 2. Then, the lighting fixture 1 performs light control by the illumination part 11 (step S12). At substantially the same time, the electronic device 2 performs light emission control by the light emitting unit 21 (step S21). Thereby, according to a light environment control system, light emission control can be performed according to light control.

  More specifically, the light environment control system may control the lighting unit 11 in the lighting fixture 1 as shown in FIG.

  In the control example illustrated in FIG. 11, the dimming value of the illumination unit 11 is changed gradually or stepwise. As illustrated in FIG. 11A, it is assumed that lighting control information for changing the dimming value to 70% is generated and transmitted from the information providing unit 10 to the lighting fixture 1 at time t1. As a result, as shown in FIG. 11B, the lighting control unit 12 is given a dimming command included in the lighting control information. As illustrated in FIG. 11C, the illumination unit 11 controls the dimming value from time t1 onward according to the dimming command included in the illumination control information. At this time, the illumination control unit 12 changes the dimming value with a gentle gradient from the time t1 to the time t2, as indicated by the curve b in FIG.

  The lighting control information for changing the dimming value is supplied from the lighting fixture 1 to the electronic device 2 after time t1. As shown in FIG. 11D, the electronic device 2 sets the light emission value of the light emitting unit 21 to 70% at time t2 after receiving the illumination control information, corresponding to the dimming value being 70%. Change to

  As another specific control example, as shown to a of FIG.11 (c), you may make the illumination control timing of the illumination part 11 and the light emission control timing of the light emission part 21 substantially simultaneous.

  Such a light environment control system transmits lighting control information from the information providing unit 10 to the lighting device 1, and transmits lighting control information from the lighting device 1 to the electronic device 2. Thereby, according to a light environment control system, light emission of the light emission part 21 can be controlled according to the light control of the illumination part 11. FIG. According to this light environment control system, even when the information providing unit 10 is operated and the brightness around the user P changes, it is possible to suppress a sense of discomfort given to the user who is viewing the screen of the electronic device 2.

  In the light environment control system described above, as shown in FIG. 12, there may be a plurality of predetermined spaces A and B, and the electronic device 2 may be controlled to emit light according to the movement between the spaces A and B. In this embodiment, the lighting fixture 1A and the electronic device 3A exist in the space A, and the lighting fixture 1B and the electronic device 3B exist in the space B.

  When the user P holds the electronic device 2 and exists in an arbitrary space A, the lighting apparatus 1A detects the electronic device 2 by the electronic device detection unit 13, and uses the electronic device 2 as a slave unit by the device setting unit 14. It is set. Thereby, since the light control value of 1 A of lighting fixtures is 100%, the light emission part 21 of the electronic device 2 is controlled by the light emission value according to the light control value.

  Thereafter, it is assumed that the user P holds the electronic device 2 and moves from the space A to the space B. At this time, the electronic device detection unit 13 of the lighting fixture 1B detects the electronic device 2, and the device setting unit 14 sets a dependency relationship with the moved electronic device 2 and sets the electronic device 2 as a slave unit. Thereby, the lighting fixture 1 </ b> B transmits lighting control information having a dimming value of 70% to the electronic device 2.

  The electronic device 2 moved to the space B receives the illumination control information transmitted from the lighting fixture 1B. Thereby, the electronic device 2 makes the light emission value of the light emission part 21 low according to the light control value being 70%.

  According to this light environment control system, the lighting control information of the lighting fixture 1B in the space B to which the electronic device 2 is moved can be instantly shared with the electronic device 2 being observed by the user P. Thereby, the light environment control system can control the light emission value of the light emission part 21 of the electronic device 2 in conjunction with the brightness reduction from the lighting fixture 1A to the lighting fixture 1B. Therefore, even if there is a sudden brightness change that occurs when the user P moves from the space A to the space B, it is possible to suppress a sense of incongruity due to the light emission change of the light emitting unit 21 of the electronic device 2 and to provide a comfortable light environment.
