[0012] The following embodiments generally relate to a lighting control system, a lighting system, a lighting control method, and a program. More specifically, the following embodiments relate to a lighting control system, a lighting system, a lighting control method, and a program that control dimming levels of lighting loads in multiple systems. Note that the embodiments described below are merely examples of embodiments of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0013] (1) Overview of environmental control systems, including lighting control systems The lighting control system of this embodiment is included in the environmental control system.

[0014] The environmental control system controls the facility environment by adjusting the facility's lighting, sound, air conditioning, ceiling fans, etc. The facility is intended to be a building such as a detached house, an apartment building, an office, a factory, or a store, but is not limited to a specific facility.

[0015] 1 includes a lighting control system C1, an acoustic control system C2, and an air conditioning control system C3, and controls the lighting environment, acoustic environment, and air conditioning environment of a facility F1. Note that it is sufficient for the environmental control system C0 to be able to control at least the lighting environment of the facility F1.

[0016] The lighting control system C1 includes a lighting operating device 1 and a lighting control device 2, and controls each of the lighting loads 3 in multiple systems (multiple groups) installed in the facility F1. In this embodiment, each of the lighting loads 3 belongs to either the first system G1 or the second system G2. In FIG. 1, three lighting loads 3 belong to the first system G1, and two lighting loads 3 belong to the second system G2. Hereinafter, the lighting loads 3 belonging to the first system G1 will be referred to as the first lighting loads 31, and the lighting loads 3 belonging to the second system G2 will be referred to as the second lighting loads 32. The lighting control system C1 and the lighting loads 3 constitute a lighting system C10.

[0017] The lighting control device 1 receives an instruction value set by a user's operation and outputs an electrical signal including data on the instruction value as an instruction value signal Y1. The lighting control device 2 receives the instruction value signal Y1 from the lighting control device 1 and controls the dimming level of the first lighting load 31 and the dimming level of the second lighting load 32 according to the instruction value set by the instruction value signal Y1. That is, the dimming level of the lighting loads 3 can be adjusted for each system by the user's operation of the lighting control device 1.

[0018] As shown in Fig. 2, the sound control system C2 includes a sound operation device 41 and a sound system 42. The sound operation device 41 accepts a user's operation and outputs an electrical signal corresponding to the operation as a sound control signal Y4 to the sound system 42. The sound system 42 is installed in the facility F1 and includes a sound playback device that plays sound source data stored on an optical disk or in a memory, and a speaker that outputs the sound played by the sound playback device. The sound system 42 adjusts the type and volume of the sound to be played in response to the sound control signal Y4.

[0019] As shown in Fig. 3, the air conditioning control system C3 includes an air conditioning operating device 51 and an air conditioning system 52. The air conditioning operating device 51 accepts a user operation and outputs an electrical signal corresponding to the operation as an air conditioning control signal Y5 to the air conditioning system 52. The air conditioning system 52 includes an air conditioner and other components installed in the facility F1. The air conditioning system 52 adjusts the temperature, humidity, air volume, and other factors within the facility F1 in response to the air conditioning control signal Y5.

[0020] (2) Lighting system The lighting system C10 includes a lighting control system C1, a first lighting load 31 of a first system G1, and a second lighting load 32 of a second system G2.

[0021] (2.1) Lighting control system configuration FIG. 4 shows a block configuration of each of the lighting operation device 1 and the lighting control device 2 included in the lighting control system C1.

[0022] (2.1.1) Lighting operating device The lighting control device 1 includes an operation unit 11 and a signal output unit 12. Fig. 5 shows the external configuration of the lighting control device 1. The lighting control device 1 is a wiring device that is attached to buildings such as the walls, ceiling, and floor of the facility F1.

[0023] The lighting control device 1 includes a hollow rectangular box-shaped housing 10 that can be attached to a building, and an operation unit 11 and a signal output unit 12 are housed in the housing 10. The operation unit 11 has one cylindrical knob 111 that protrudes from the front surface of the housing 10 to the outside. In this way, by using only one operation unit 11 that the user operates to control dimming, operation by the user can be simplified.

[0024] The knob 111 is rotated by the user. As the knob 111 rotates clockwise R1, the rotation angle of the knob 111 increases. As the knob 111 rotates counterclockwise R2, the rotation angle of the knob 111 decreases. The rotation angle of the knob 111 has upper and lower limit angles set by a stopper or the like, and the rotation angle of the knob 111 is variable within a range between the lower limit angle and the upper limit angle.

[0025] When the user rotates the knob 111, the operation unit 11 sets an instruction value as a parameter corresponding to the rotation angle of the knob 111. The instruction value is expressed, for example, as a resistance value or a voltage value. When the rotation angle of the knob 111 is at the lower limit angle, the instruction value becomes a first instruction value X1 (see FIGS. 6A and 6B), and when the rotation angle of the knob 111 is at the upper limit angle, the instruction value becomes a second instruction value X2 (see FIGS. 6A and 6B). In this embodiment, the second instruction value X2 is larger than the first instruction value X1. Therefore, the settable range of the instruction value by the operation unit 11 is equal to or larger than the first instruction value X1 and equal to or smaller than the second instruction value X2. That is, the operation unit 11 can set the instruction value between the first instruction value X1 and the second instruction value X2.

[0026] Communication between the lighting operating device 1 and the lighting control device 2 is performed by wired communication via a communication line or wireless communication using wireless signals. Wired communication is, for example, wired communication via a twisted pair cable, a dedicated communication line, or a LAN (Local Area Network) cable. Wireless communication is, for example, wireless communication compliant with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or unlicensed low-power wireless (specified low-power wireless), or wireless communication such as infrared communication.

[0027] For example, the signal output unit 12 outputs an electrical signal containing data on the indication value set by the operation unit 11 as an indication value signal Y1 to a two-wire communication line. The indication value signal Y1 is, for example, a signal of a time division multiplexing transmission system. As a communication protocol for the time division multiplexing transmission system, for example, the NMAST (registered trademark) communication standard can be adopted. The signal output unit 12 outputs a bipolar (±24 V) time division multiplexing signal as a wired signal and transmits the indication value signal Y1 containing data on the indication value by pulse width modulation. Furthermore, the indication value signal Y1 may be an analog voltage signal that represents the indication value by the magnitude of the voltage, an analog current signal that represents the indication value by the magnitude of the current, or a digital signal that represents the indication value by a multi-bit digital value.

[0028] Furthermore, the operation unit 11 may include, in addition to the knob 111 that is rotated by the user, one knob that is slid or one button that is pressed. Furthermore, the knob or button may be formed on a touch panel.

[0029] The lighting control device 1 preferably includes a computer. The computer executes a program to realize at least the functions of the signal output unit 12 of the lighting control device 1. The computer's main hardware component is a processor that operates according to the program. The processor can be of any type, as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integration (LSI). While ICs and LSIs are used here, the names may vary depending on the degree of integration, and may be referred to as system LSIs, very large-scale integrations (VLSIs), or ultra-large-scale integrations (ULSIs). Field-programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, or reconfigurable logic devices that can reconfigure the connections within the LSI or set up circuit partitions within the LSI, can also be used for the same purpose. Multiple electronic circuits may be integrated on a single chip or on multiple chips. The program is recorded on a non-transitory recording medium, such as a computer-readable ROM, optical disk, or hard disk drive. The program may be stored in advance on a non-transitory recording medium, or may be supplied to the non-transitory recording medium via a wide area communication network including the Internet.

[0030] (2.1.2) Lighting control devices As shown in FIG. 4, the lighting control device 2 includes a control unit 21, a storage unit 22, and a setting unit 23.

[0031] The control unit 21 acquires instruction value data from the instruction value signal Y1. Then, the control unit 21 controls the dimming level of the lighting load 3 for each system to the dimming target value for each system based on the correspondence relationship between the instruction value and the dimming target value of each of the multiple systems to which the lighting load 3 belongs. If the dimming target value of the first lighting load 31 is set to a first dimming target value, the control unit 21 controls the dimming level of the first lighting load 31 based on the correspondence relationship between the first dimming target value and the instruction value so that the dimming level of the first lighting load 31 matches the first dimming target value. If the dimming target value of the second lighting load 32 is set to a second dimming target value, the control unit 21 controls the dimming level of the second lighting load 32 based on the correspondence relationship between the second dimming target value and the instruction value so that the dimming level of the second lighting load 32 matches the second dimming target value.

[0032] In this embodiment, the control unit 21 can transmit and receive signals to and from each of the multiple lighting loads 3 via the control line SL1. Each of the multiple lighting loads 3 is a first lighting load 31 belonging to the first system G1 or a second lighting load 32 belonging to the second system G2. Identification information of the first system G1 is assigned to the first lighting load 31, and identification information of the second system G2 is assigned to the second lighting load 32. The control unit 21 controls the dimming of the first lighting load 31 by sending a dimming signal, in which a first dimming target value is associated with the identification information of the first system G1, to the control line SL1. The control unit 21 also controls the dimming of the second lighting load 32 by sending a dimming signal, in which a second dimming target value is associated with the identification information of the second system G2, to the control line SL1. In this way, the control unit 21 can control the dimming levels of the lighting loads 3 of the multiple systems for each system. In the following description, when there is no need to distinguish between the first dimming target value and the second dimming target value, they will simply be referred to as dimming target values.

[0033] The storage unit 22 stores the correspondence relationship between the first dimming target value and the instruction value as first correspondence data D1. The storage unit 22 stores the correspondence relationship between the second dimming target value and the instruction value as second correspondence data D2. That is, the first correspondence data D1 and the second correspondence data D2 are set separately. In other words, the correspondence relationship between the first dimming target value and the instruction value and the correspondence relationship between the second dimming target value and the instruction value are set independently, and the correspondence relationship for each system is set separately for each system. Note that the storage unit 22 is preferably a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read Only Memory) or a flash memory.

[0034] FIG. 6A shows an example of the first correspondence data D1. In the first correspondence data D1, the first dimming target value increases linearly as the instruction value increases, and decreases linearly as the instruction value decreases. In FIG. 6A, the first instruction value X1 corresponds to the first dimming target value Y11, and the second instruction value X2 corresponds to the first dimming target value Y12. That is, the first correspondence data D1 has a change characteristic in which the first dimming target value changes linearly with a positive slope between the control point P11 (X1, Y11) and the control point P12 (X2, Y12). The controller 21 can then determine the first dimming target value by comparing the instruction value with the first correspondence data D1. As a result, the controller 21 linearly increases the dimming level of the first lighting load 31 as the instruction value increases, and linearly decreases the dimming level of the first lighting load 31 as the instruction value decreases.

[0035] FIG. 6B shows an example of the second correspondence data D2. In the second correspondence data D2, the second dimming target value linearly decreases as the instruction value increases, and linearly increases as the instruction value decreases. In FIG. 6B, the first instruction value X1 corresponds to the second dimming target value Y22, and the second instruction value X2 corresponds to the second dimming target value Y21. That is, the second correspondence data D2 has a change characteristic in which the dimming level changes linearly with a negative slope between the control point P21 (X1, Y22) and the control point P22 (X2, Y21). The controller 21 can then determine the second dimming target value by comparing the instruction value with the second correspondence data D2. As a result, the controller 21 linearly decreases the dimming level of the second lighting load 32 as the instruction value increases, and linearly increases the dimming level of the second lighting load 32 as the instruction value decreases.

[0036] The setting unit 23 sets a correspondence relationship between the dimming target value and the instruction value for each of the multiple systems. The setting unit 23 sets a change characteristic of the dimming target value relative to the instruction value as the correspondence relationship. In this embodiment, the setting unit 23 sets first correspondence data D1, which is the correspondence relationship between the first dimming target value and the instruction value. The setting unit 23 also sets second correspondence data D2, which is the correspondence relationship between the second dimming target value and the instruction value.

[0037] Specifically, the lighting control device 2 is configured to be able to communicate with a setting terminal 8 (see FIG. 4 ), such as a tablet terminal, smartphone, or personal computer operated by a user or administrator. The setting terminal 8 creates setting information, including first correspondence data D1 and second correspondence data D2, in response to a user's operation on the setting terminal 8, and transmits the setting information to the lighting control device 2. The setting unit 23 creates the first correspondence data D1 and second correspondence data D2 based on a setting signal received by the lighting control device 2 from the setting terminal 8, and stores the first correspondence data D1 and second correspondence data D2 in the memory unit 22.

[0038] Communication between the lighting control device 2 and the setting terminal 8 is performed by wired communication via a communication line or wireless communication using wireless signals. Wired communication is, for example, wired communication via a twisted pair cable, a dedicated communication line, or a LAN cable. Wireless communication is, for example, wireless communication compliant with standards such as Wi-Fi, Bluetooth, ZigBee, or unlicensed low-power wireless (specified low-power wireless), or wireless communication such as infrared communication.

[0039] Preferably, the lighting control device 2 includes a computer. At least some of the functions of the lighting control device 2 are realized by the computer executing a program.

[0040] (2.2) Lighting load As shown in FIG. 7, the lighting load 3 includes a power adjustment unit 3a and a light source 3b.

[0041] The power adjustment unit 3a supplies power to the light source 3b and adjusts the power supplied to the light source 3b. That is, the power adjustment unit 3a adjusts the power supplied to the light source 3b to dim the light of the light source 3b.

[0042] Specifically, the power adjustment unit 3a has a voltage conversion circuit that receives an AC input voltage from an AC power source PS, which includes at least one of a commercial power system and a power source that uses renewable energy, and converts the input voltage into a predetermined DC output voltage. The voltage conversion circuit is configured with a chopper circuit having a switching element, etc. The power adjustment unit 3a applies the output voltage to the light source 3b, supplying power to the light source 3b. Note that the input voltage to the power adjustment unit 3a may be a DC voltage.

[0043] The power adjustment unit 3a is connected to the control line SL1 and receives a dimming signal via the control line SL1 from the lighting control device 2. The power adjustment unit 3a adjusts the dimming level of the light source 3b to the dimming target value based on the dimming target value data included in the dimming signal of the system to which the lighting load 3 belongs.

[0044] The light source 3b includes a solid-state light-emitting element such as an LED (Light Emitting Diode) or an organic EL (Organic Light Emitting Diode), and irradiates the space within the facility F1 with illumination light. Note that the light source 3b may be a light source other than a solid-state light-emitting element.

[0045] Each of the plurality of lighting loads 3 is a first lighting load 31 belonging to the first system G1 or a second lighting load 32 belonging to the second system G2. The first lighting load 31 of the first system G1 irradiates a first space 91 of the facility F1 with illumination light, and the second lighting load 32 of the second system G2 irradiates a second space 92 of the facility F1 with illumination light (see FIG. 4 ). It is preferable that the first space 91 and the second space 92 are different spaces. For example, if the facility F1 is a residence, the first space 91 may be a dining room and the second space 92 may be a living room. Alternatively, the first space 91 may be indoors and the second space 92 may be an entrance porch. Alternatively, the first space 91 and the second space 92 may be the same space. Note that the first space 91 and the second space 92 may be any space within the facility F1, and are not limited to any specific space.

[0046] The first lighting load 31 is assigned identification information of the first system G1, and the second lighting load 32 is assigned identification information of the second system G2. When the first lighting load 31 receives a dimming signal including the identification information of the first system G1 from the control unit 21, it can adjust its dimming level to a first dimming target value based on data of a first dimming target value included in the dimming signal. Furthermore, when the second lighting load 32 receives a dimming signal including identification information of the second system G2 from the control unit 21, it can adjust its dimming level to a second dimming target value based on data of a second dimming target value included in the dimming signal.

[0047] Therefore, the first lighting load 31 can adjust the illuminance of the first space 91 based on the dimming signal transmitted by the lighting control device 2. The second lighting load 32 can adjust the illuminance of the second space 92 based on the dimming signal transmitted by the lighting control device 2.

[0048] Although FIG. 4 illustrates wired communication using the control line SL1 as an example of communication between the control unit 21 and the lighting load 3, wireless communication may also be used.

[0049] Furthermore, the illumination light of the first lighting load 31 and the illumination light of the second lighting load 32 may be either the same color (same color temperature) or different colors (different color temperatures). If the illumination light of the first lighting load 31 and the illumination light of the second lighting load 32 are different colors, the lighting system C10 can expand the adjustment range of the lighting environment for each system.

[0050] (2.3) Operation of the lighting control system (2.3.1) Dimming operation The dimming operation of the lighting control system C1 will be described below with reference to the flowchart of FIG.

[0051] The user changes the instruction value by operating the operation unit 11 of the lighting operation device 1 (by rotating the knob 111). The lighting operation device 1 outputs an instruction value signal Y1 including data of the instruction value set by the user to the lighting control device 2. In the lighting control device 2, the control unit 21 receives the instruction value signal Y1 from the lighting operation device 1 and acquires the instruction value data from the instruction value signal Y1 (acquisition step S1).

[0052] Next, the control unit 21 controls the dimming level of the lighting load 3 for each system to the dimming target value for each system based on the correspondence relationship between the dimming target value and the instruction value for each of the multiple systems to which the lighting load 3 belongs (control step S2). Specifically, the control unit 21 obtains a first dimming target value for the first lighting load 31 by comparing the instruction value with the first correspondence data D1, and controls the dimming level of the first lighting load 31 to the first target value. Furthermore, the control unit 21 obtains a second dimming target value for the second lighting load 32 by comparing the instruction value with the second correspondence data D2, and controls the dimming level of the second lighting load 32 to the second target value.

[0053] For example, it is assumed that the first corresponding data D1 has the change characteristic shown in FIG. 6A, and the second corresponding data D2 has the change characteristic shown in FIG. 6B.

[0054] In this case, when the instruction value is X1, the control unit 21 controls the dimming of the first lighting load 31 at the control point P11 (X1, Y11), and controls the dimming of the second lighting load 32 at the control point P21 (X1, Y22). That is, when the instruction value is X1, the dimming level of the first lighting load 31 becomes the first dimming target value Y11, and the dimming level of the second lighting load 32 becomes the second dimming target value Y22.

[0055] Furthermore, when the instruction value is X2, the control unit 21 controls the dimming of the first lighting load 31 at the control point P12 (X2, Y12), and controls the dimming of the second lighting load 32 at the control point P22 (X2, Y21). That is, when the instruction value is X2, the dimming level of the first lighting load 31 becomes the first dimming target value Y12, and the dimming level of the second lighting load 32 becomes the second dimming target value Y21.

[0056] Then, when the instruction value increases from X1 to X3 (see FIGS. 6A and 6B) by operation of the operation unit 11 of the lighting operation device 1, the controller 21 controls the dimming of the first lighting load 31 at control point P13 (X3, Y13) and controls the dimming of the second lighting load 32 at control point P23 (X3, Y23). That is, when the instruction value increases from X1 to X3, the dimming level of the first lighting load 31 increases from the first dimming target value Y11 to the first dimming target value Y13, and the dimming level of the second lighting load 32 decreases from the second dimming target value Y22 to the second dimming target value Y23. Furthermore, when the instruction value is decreased from X2 to X3 by operation of the operation unit 11 of the lighting operation device 1, the dimming level of the first lighting load 31 decreases from the first dimming target value Y12 to the first dimming target value Y13, and the dimming level of the second lighting load 32 increases from the second dimming target value Y21 to the second dimming target value Y23. Note that the instruction value X3 is greater than the first instruction value X1 and less than the second instruction value X2. The first dimming target value Y13 is greater than the first dimming target value Y11 and less than the first dimming target value Y12. The second dimming target value Y23 is greater than the second dimming target value Y21 and less than the second dimming target value Y22.

[0057] Note that the control unit 21 can perform dimming control on the first lighting load 31 even at a control point other than the above-mentioned control points P11 (X1, Y11), P12 (X2, Y12), and P13 (X3, Y13) on the first correspondence data D1. Furthermore, the control unit 21 can perform dimming control on the second lighting load 32 even at a control point other than the above-mentioned control points P21 (X1, Y22), P22 (X2, Y21), and P23 (X3, Y23) on the second correspondence data D2.

[0058] In this way, as the instruction value increases, the dimming level of the first lighting load 31 increases, and the dimming level of the second lighting load 32 decreases. On the other hand, as the instruction value decreases, the dimming level of the first lighting load 31 decreases, and the dimming level of the second lighting load 32 increases. In other words, the dimming levels of the first lighting load 31 and the second lighting load 32 are controlled independently of each other according to the instruction value, which is a single parameter generated by the lighting operating device 1. Therefore, the user can control the dimming levels of the first lighting load 31 and the second lighting load 32 independently of each other by simply operating the single operating unit 11.

[0059] That is, the lighting control system C1 can perform dimming control on the lighting loads 3 (first lighting load 31 and second lighting load 32) of multiple systems (first system G1 and second system G2) for each system with a simple operation.

[0060] Furthermore, the dimming level of the first lighting load 31 and the dimming level of the second lighting load 32 change in opposite directions with respect to a change in the instruction value. This makes it easier to set the lighting environment of the first space 91 and the lighting environment of the second space 92 to different lighting environments.

[0061] (2.3.2) Setting operation The following describes how the setting unit 23 sets the first correspondence data D1 and the second correspondence data D2. The first correspondence data D1 is data that represents the correspondence relationship between the first dimming target value and the instruction value. The second correspondence data D2 is data that represents the correspondence relationship between the second dimming target value and the instruction value.

[0062] In response to a user's operation on the setting terminal 8, the setting terminal 8 generates setting information of the first correspondence data D1 as the first setting information and creates setting information of the second correspondence data D2 as the second setting information. The first setting information includes, for example, data on a pair of control points P11 (X1, Y11) and P12 (X2, Y12) (see FIGS. 6A and 6B). The second setting information includes, for example, data on a pair of control points P21 (X1, Y22) and P22 (X2, Y21) (see FIGS. 6A and 6B). The setting terminal 8 transmits the first setting information and the second setting information to the lighting control device 2. Note that FIGS. 6A and 6B conceptually represent the relationship between light emission luminance (or illuminance) and human luminosity as linear.

[0063] When the lighting control device 2 receives the first setting information and the second setting information, the setting unit 23 generates first correspondence data D1 based on the first setting information and generates second correspondence data D2 based on the second setting information.

[0064] For example, the setting unit 23 generates correspondence data by linearly interpolating between a pair of control points. In this case, when the setting unit 23 receives data of a pair of control points P11 (X1, Y11) and P12 (X2, Y12) as the first setting information, the setting unit 23 performs linear interpolation between the control points P11 and P12 to generate first correspondence data D1 (see FIG. 6A). Furthermore, when the setting unit 23 receives data of a pair of control points P21 (X1, Y22) and P22 (X2, Y21) as the second setting information, the setting unit 23 performs linear interpolation between the control points P21 and P22 to generate second correspondence data D2 (see FIG. 6B).

[0065] The setting unit 23 may also generate correspondence data by performing quadratic function interpolation between a pair of control points. For example, when the setting unit 23 receives data on a pair of control points P31 (X1, Y31) and P32 (X2, Y32) as setting information as shown in FIG. 9, the setting unit 23 performs quadratic function interpolation between the control points P31 and P32 to generate correspondence data D3 (solid line). Because the dimming target value Y32 is greater than the dimming target value Y31, the dimming target value changes in a curve with a positive slope between the control points P31 (X1, Y31) and P32 (X2, Y32) in the correspondence data D3. When the setting unit 23 receives data on a pair of control points P33 (X1, Y32) and P34 (X2, Y31) as setting information as shown in FIG. 9, the setting unit 23 performs quadratic function interpolation between the control points P33 and P34 to generate correspondence data D3a (dashed dotted line). Between control point P33 (X1, Y32) and control point P34 (X2, Y31) of correspondence data D3a, the dimming target value changes in a curve with a negative slope. Note that setting unit 23 may use other interpolation methods such as cubic function interpolation and cosine interpolation.

[0066] Alternatively, one of a plurality of completion functions may be selected by a user's operation on setting terminal 8, and the data of the selected completion function may be included in the setting information. In this case, setting unit 23 refers to the setting information and determines the completion function to be used for completion.

[0067] Furthermore, the setting unit 23 may receive data of three or more control points from the setting terminal 8 and generate correspondence data that passes through three or more control points. In this case, the user specifies the control points, and the setting unit 23 automatically creates the correspondence data based on predetermined rules or rules created by the user.

[0068] Furthermore, the user can also fine-tune the correspondence data created by the setting unit 23.

[0069] In this way, the lighting control system C1 can easily set the dimming characteristics of each system to the desired dimming characteristics. Also, the lighting control system C1 can easily set the dimming characteristics of each system.

[0070] (3) Variations (3.1) Color matching control As lighting control for the lighting load 3, the lighting control system C1 preferably performs color adjustment control for the lighting load 3 in addition to dimming control for the lighting load 3. In this case, the lighting load 3 has, for example, a red LED, a green LED, and a blue LED as light sources 3b (see FIG. 7). The power adjustment unit 3a of the lighting load 3 adjusts the color of the illumination light emitted by the light source 3b by changing the output ratio of the red LED, the green LED, and the blue LED.

[0071] Specifically, power adjustment unit 3a (see FIG. 7) controls color adjustment by changing the color temperature of the illumination light emitted by light source 3b within a range of 2700K to 5000K. As the dimming level of light source 3b decreases, power adjustment unit 3a lowers the color temperature of the illumination light, and as the dimming level of light source 3b increases, power adjustment unit 3a raises the color temperature of the illumination light. In other words, as the dimming level of light source 3b decreases, the illumination light becomes closer to incandescent white, and as the dimming level of light source 3b increases, the illumination light becomes closer to daylight white.

[0072] In this modification, the lighting control system C1 performs color adjustment control in conjunction with dimming control, further expanding the range of adjustment of the lighting environment.

[0073] (3.1.1) Coordination of color control and sound control 1 and 2, in the environmental control system C0, the audio operation device 41 of the audio control system C2 is connected to the control line SL1, and the audio operation device 41 can receive a dimming signal transmitted from the lighting control system C1 (lighting control device 2). Then, the audio operation device 41 controls the audio system 42 in response to the dimming signal.

[0074] Specifically, the sound system 42 provides a sound environment independently for each of the first space 91 and the second space 92. Here, the lighting load 3 providing the lighting environment for the first space 91 is the first lighting load 31, and the lighting load 3 providing the lighting environment for the second space 92 is the second lighting load 32. The sound control device 41 controls the sound environment for the first space 91 by controlling the sound system 42 in response to a dimming signal addressed to the first lighting load 31. The sound control device 41 also controls the sound environment for the second space 92 by controlling the sound system 42 in response to a dimming signal addressed to the second lighting load 32.

[0075] In a dimming signal addressed to the first lighting load 31, the first dimming target value is associated with the identification information of the first system G1. Therefore, the acoustic operation device 41 can know the first dimming target value, which is the dimming target value of the first lighting load 31, from the dimming signal. Meanwhile, in a dimming signal addressed to the second lighting load 32, the second dimming target value is associated with the identification information of the second system G2. Therefore, the acoustic operation device 41 can know the second dimming target value, which is the dimming target value of the second lighting load 32, from the dimming signal.

[0076] In this modification, as described in (3.1) Color Adjustment Control above, the lower the dimming level of the light source 3b, the lower the color temperature of the illumination light, and the higher the dimming level of the light source 3b, the higher the color temperature of the illumination light. That is, the smaller the first dimming target value, the lower the color temperature of the illumination light of the first lighting load 31. Therefore, the audio control device 41 increases the volume of the music output by the audio system 42 to the first space 91 as the first dimming target value decreases. In this case, the lower the color temperature of the illumination light of the first lighting load 31, the higher the volume of the music output to the first space 91. Furthermore, the smaller the second dimming target value, the lower the color temperature of the illumination light of the second lighting load 32. Therefore, the smaller the second dimming target value, the audio control device 41 increases the volume of the music output by the audio system 42 to the second space 92. In this case, the lower the color temperature of the illumination light of the second lighting load 32, the higher the volume of the music output to the second space 92.

[0077] Here, when the lighting control system C1 increases the dimming level of the first lighting load 31, it decreases the dimming level of the second lighting load 32, and when it decreases the dimming level of the first lighting load 31, it increases the dimming level of the second lighting load 32. Therefore, when the volume of the music provided to the first space 91 increases, the volume of the music provided to the second space 92 decreases, and when the volume of the music provided to the first space 91 decreases, the volume of the music provided to the second space 92 increases. In other words, as the instruction value increases from the first instruction value X1 to the second instruction value X2, the volume of the music provided to the first space 91 changes from low to high, and the volume of the music provided to the second space 92 changes from high to low.

[0078] Furthermore, sound control device 41 may set the volume of music provided to the space to zero if the dimming target value is either the lower limit or the upper limit. If the dimming target value is greater than the lower limit and less than the upper limit, sound control device 41 changes the volume of music provided to the space in accordance with the color temperature of the space. For example, as the instruction value increases from first instruction value X1 to second instruction value X2, the volume of music provided to first space 91 changes from 0 to high to low to 0, and the volume of music provided to second space 92 changes from 0 to low to high to 0.

[0079] Furthermore, sound control device 41 may set the volume of music provided to the space to zero if the dimming target value is within a predetermined range including the lower limit. Alternatively, sound control device 41 may set the volume of music provided to the space to zero if the dimming target value is within a predetermined range including the upper limit. For example, as the instruction value increases from first instruction value X1 to second instruction value X2, the volume of music provided to first space 91 changes from 0 to 0 to low to high, and the volume of music provided to second space 92 changes from high to low to 0 to 0.

[0080] The specific configuration for linking the color adjustment control and the sound control is not limited to the above-described configuration.

[0081] (3.1.2) Coordination of color adjustment control and air conditioning control 1 and 3, in the environmental control system C0, an air conditioning operating device 51 of an air conditioning control system C3 is connected to a control line SL1, and the air conditioning operating device 51 can receive a dimming signal transmitted from the lighting control system C1 (lighting control device 2). The air conditioning operating device 51 then controls the air conditioning system 52 in response to the dimming signal.

[0082] For example, the air conditioning operating device 51 controls the temperature or humidity of the space according to the dimming level of the lighting load 3 or the color temperature of the illumination light.

[0083] (3.1.3) Coordination of color matching control with other controls In the environmental control system C0, volume control such as television volume control and telephone ring volume control may be linked to color adjustment control.

[0084] Furthermore, in the environmental control system C0, the color adjustment control may be linked to the opening and closing control of the windows, curtains, blinds, etc. of the facility F1. For example, when the color temperature of the illumination light drops below a predetermined temperature, the windows, curtains, blinds, etc. are controlled to close, and when the color temperature of the illumination light rises above the predetermined temperature, the windows, curtains, blinds, etc. are controlled to open.

[0085] (3.2) Other The lighting control device 2 may be installed either inside the facility F1 or outside the facility F1. For example, the lighting operating device 1 and the lighting load 3 may belong to an indoor network of the facility F1, and the lighting control device 2 may be an external server device configured to be able to communicate with the indoor network via a wide area network such as the Internet.

[0086] Furthermore, the lighting control device 2 is not limited to being separate from the lighting operation device 1 and the lighting load 3, and the lighting operation device 1 and the lighting control device 2 may be configured as an integrated unit. That is, the functions of the lighting control device 2 may be incorporated into the lighting operation device 1. Alternatively, the lighting load 3 and the lighting control device 2 may be configured as an integrated unit. That is, the functions of the lighting control device 2 may be incorporated into the lighting load 3.

[0087] Furthermore, the number of systems in the lighting control system C1 is not limited to two, and may be three or more. Furthermore, the number of lighting loads 3 belonging to each system may be one or more.
