The detection unit 21 detects which of the four switches is operated (for example, pressed). For example, it may be detected that the switch has been operated by detecting that the switch has been operated and energized. Then, the detection unit 21 outputs the detection result to the control unit 22.

The control unit 22 is a control device that performs various controls of the lighting control device 20. When the detection unit 21 detects the operation of the switch units 40 (switches 40a to 40d), the control unit 22 controls the lighting state of the lighting fixture 30 according to the switches 40a to 40d detected by the detection unit 21. Although details will be described later, information on a group of lighting fixtures and information on the lighting state of the lighting fixtures included in the group (for example, scene information or slide show information) are assigned to each of the switches 40a to 40d. ing. In other words, the information regarding each group of the switches 40a to 40d and the information regarding the lighting state are stored in the storage unit 25. When the detection unit 21 detects the operation of the switch (for example, the switch 40a), the control unit 22 reads out the information about the group corresponding to the switch 40a operated from the storage unit 25, the scene information or the slide show information, and sets the group. The dimming rate and color temperature indicated by the scene information or slide show information obtained by reading the included lighting equipment are controlled.

As shown in FIG. 4, the slide show information is information in which two or more scene informations are combined. The slide show information includes the reproduction order, the scene information, and the reproduction time. In the present embodiment, the slide show information includes five scene information from scene information 1 to scene information 5. For example, when the lighting state is controlled based on the slide show information, the reproduction is performed in order from the reproduction order 1. In the present embodiment, the reproduction order is 1 to 5, and when the lighting of the reproduction order 5 (for example, the lighting state indicated by the scene information 1 is continued for 4 minutes) is completed, the reproduction order 1 is restored and the lighting fixture 30 is used. The lighting state is controlled.

The slide show information is stored in advance by the user in the storage unit 25 of the lighting control device 20 via the terminal device 50. As a result, the lighting control device 20 can reproduce the dimming rate and the color temperature shown in the schedule information by reading the schedule information included in the control information from the storage unit 25.

The repetitive information or time information is information related to the reproduction of the lighting state indicated by the scene information or the slide show information. Specifically, the repetition information is information indicating the number of times (the number of loops) that the lighting state of the slide show information is repeated. Further, the time information is information indicating the time for which the lighting state of the scene information or the slide show information is continued. The time information is the duration for continuously reproducing the lighting state indicated by the scene information or slide show information after the detection unit 21 detects the operation from the switch unit 40, or the lighting state indicated by the scene information or slide show information. Includes the end time to end the reproduction. In the lighting system 10 according to the present embodiment, the lighting information C includes repetitive information or time information, and the lighting control device 20 lights the lighting fixture 30 based on the repetitive information or time information included in the lighting information C. It is characterized by the fact that it continues the state.

FIG. 5 is a diagram showing an example of an operation when the lighting control device 20 according to the present embodiment reproduces the lighting state shown in the schedule information. The schedule information includes at least one scene information (an example of the second scene information) or slide show information (an example of the second slide show information) in which two or more scene informations are combined, and lighting indicated by the scene information or the slide show information. This is information associated with time information related to state reproduction. The time information is, for example, time information. FIG. 5 shows an example of the operation when the lighting control device 20 reproduces the scene information and the slide show information based on the schedule information. The schedule information is composed of five scene information, one slide show information, and time information indicating the start and end of each lighting information.

The schedule information does not include information about switches and information about groups. Further, the schedule information is information for controlling all the lighting fixtures 30 included in the lighting system 10. When the lighting control device 20 receives a predetermined operation (for example, an operation from the terminal device 50) by the user via the communication unit 24, the lighting control device 20 controls the lighting state of the lighting fixture 30 based on the schedule information. .. The lighting of the lighting fixture 30 in the schedule information is a normal lighting mode.

The schedule information may be set for each day, and can be arbitrarily set by the user, for example, for each day of the week, every month, every season, every year, and the like.

The control information such as lighting information C, scene information, slide show information, and schedule information described above is information acquired by the lighting control device 20 via the terminal device 50. The lighting control device 20 acquires lighting information C, scene information, slide show information, and schedule information of the lighting equipment 30 input by the user using the terminal device 50 via the communication unit 24, and each acquired information is obtained. It is stored in the storage unit 25.

[2. Generation of lighting information]
Subsequently, the generation of lighting information C stored in the storage unit 25 of the lighting control device 20 and including information on the group corresponding to the switch and the lighting state will be described.

The lighting information C is generated by the user using the terminal device 50. The procedure for generating the lighting information C by the user will be described with reference to FIG. FIG. 6 is a flowchart showing a procedure for generating lighting information C according to the present embodiment. It is assumed that the scene information, the slide show information, and the information about the group are stored in advance in the storage unit 25 of the lighting control device 20. Further, it is assumed that the terminal device 50 has acquired the information about the switch unit 40 included in the lighting system 10 (in the present embodiment, the information about the switches 40a to 40d) from the lighting control device 20.

First, the user selects a switch that generates lighting information from the acquired information of the switch unit 40 (S10). In the present embodiment, a switch that generates lighting information is selected from the four switches 40a to 40d. For example, switches 40a to 40d are displayed on the display unit 52, and the user selects the switch via the acquisition unit 51. For example, suppose that switch 40a is selected.

Next, the user selects a group controlled by the selected switch 40a (in other words, assigned to the switch 40a) (S20). For example, the group information stored in advance is displayed on the display unit 52, and the user selects an intended group via the acquisition unit 51. As a result, the switch 40a and the group are associated with each other. For example, suppose the user selects group 1. If the group is not set in advance or if you want to set a new group, you may set a new group in step S20.

When a predetermined group (group 1 corresponding to the switch 40a in the present embodiment) is set in step S20, scene information or slide show information of the lighting fixture 30 included in the predetermined group is selected (S30). For example, the scene information or slide show information stored in advance is displayed on the display unit 52, and the user selects the intended scene information or slide show information via the acquisition unit 51. As a result, the switch 40a is associated with the scene information or the slide show information. For example, it is assumed that the user selects scene information 1.

When the scene information or the slide show information is selected in step S30, the repeat information or the time information that keeps the lighting state indicated by the selected scene information or the slide show information is set (S40). The present embodiment is characterized in that the repetitive information or the time information is set.

The user may input the number of repetitions, the duration, the end time, and the like via, for example, the acquisition unit 51, or one or more repetition information or time information is stored in advance, and the stored repetition information or time information is stored. Predetermined repetition information or time information may be selected from. As a result, the switch 40a is associated with the repetition information or the time information. For example, suppose the user inputs 30 minutes.

This completes the generation of lighting information in one switch. Then, when the generation of lighting information is completed for all the switches included in the lighting system 10 (Yes in S50), the generated lighting information is transmitted to the lighting control device 20 via the communication unit 54 (Yes). S60). For example, when the acquisition unit 51 receives a transmission instruction from the user, the lighting information is transmitted.

If the generation of lighting information is not completed for all the switches included in the lighting system 10 (No in S50), the process returns to step S10, and steps S10 to S40 are performed for the remaining switches.

In steps S10 to S40, the switch 40a is assigned group 1, scene information or slide show information 1, scene information 1, and repetition information or time information 30 minutes. That is, when the switch 40a is operated, the control unit 22 of the lighting control device 20 can control the lighting fixture 30 included in the group 1 to be turned on for only 30 minutes in the lighting state indicated by the scene information 1.

[3. Operation of lighting control device]
Subsequently, the operation of the lighting control device 20 in the lighting system 10 will be described with reference to FIGS. 7 to 8B. FIG. 7 is a flowchart showing the operation of the lighting control device 20 according to the present embodiment.

In the following description, it is assumed that the schedule information and the lighting information C corresponding to the switch unit 40 are stored in advance in the storage unit 25. Further, the plurality of lighting fixtures 30 included in the lighting system 10 are lit based on the schedule information, and when the switch of the switch unit 40 is pressed (operated) at the time of pressing the switch shown in FIG. Will be described. Further, in the following, as an example, a case where the switch 40a and the switch 40b are pressed will be described.

First, when the lighting control device 20 receives a lighting instruction based on the schedule information by the user (Yes in S110), the lighting control device 20 controls the lighting state of the plurality of lighting fixtures 30 included in the lighting system 10 to the lighting state based on the schedule information. (S120). Specifically, when a lighting instruction based on the schedule information is received via the communication unit 24, the control unit 22 reads the schedule information from the storage unit 25. Further, the control unit 22 acquires the current time information from the timer unit 23. Then, the control unit 22 controls the lighting state of the schedule information corresponding to the acquired time information of the plurality of lighting fixtures 30. The control unit 22 controls the lighting state of the plurality of lighting fixtures 30 by transmitting a control signal according to the lighting state indicated by the schedule information to each of the plurality of lighting fixtures 30 via the transmission unit 26. The control for reproducing the lighting state indicated by the schedule information on the lighting fixture 30 is an example of the second control performed by the control unit 22.

For example, when a lighting instruction based on the schedule information shown in FIG. 5 is received at 10:30, the control unit 22 has a plurality of lighting instructions based on the slide show information 1 which is a lighting state corresponding to 10:30 of the schedule information. The lighting state of the lighting fixture 30 is controlled.

The schedule information is information that collectively controls all the lighting fixtures 30 included in the lighting system 10. Therefore, when the control unit 22 receives the lighting instruction based on the schedule information, the control unit 22 collectively controls the lighting states of all the lighting fixtures 30 included in the lighting system 10.

Further, the lighting instruction based on the schedule information is, for example, an instruction received from the terminal device 50. In other words, it is not an instruction by operating the switch unit 40.

Further, when the lighting instruction based on the schedule information is not received (No in S110), the lighting control device 20 does not control the lighting state of the lighting fixture 30. For example, if the lighting fixture 30 is off, the lighting control device 20 maintains the lighting fixture 30 off. Further, for example, if the luminaire 30 is lit based on some instruction, the lighting control device 20 keeps the luminaire 30 lit.

When the detection unit 21 detects the operation of the switch unit 40 (Yes in S130) while the lighting is on based on the schedule information, the control unit 22 reads the lighting information C corresponding to the switch unit 40 from the storage unit 25. (S140), the lighting state of a predetermined group included in the read lighting information C is controlled to the lighting state indicated by the scene information or slide show information included in the lighting information C (S150). The control for reproducing the lighting state indicated by the lighting information C on the lighting fixture 30 is an example of the first control performed by the control unit 22.

If the detection unit 21 does not detect the operation of the switch unit 40 (No in S130) when it is lit based on the schedule information, the control unit 21 detects the operation of the switch unit 40. 22 continues the control based on the schedule information.

Here, as an example, the lighting state of the luminaire when the switch 40a or the switch 40b is pressed while the schedule information of FIG. 5 is lit will be described with reference to FIGS. 8A and 8B. First, a case where the switch 40a is pressed while the schedule information is lit will be described with reference to FIG. 8A. The timing at which the switch is pressed is the timing shown in FIG.

FIG. 8A is a diagram showing a lighting state of the lighting fixture 30 for each group when the switch 40a according to the present embodiment is pressed. Specifically, FIG. 8A (a) is a diagram showing a lighting state of the lighting fixture 30 included in Group 1 when the switch 40a according to the present embodiment is pressed, and FIG. 8A (b) is a diagram. Is a diagram showing a lighting state of the lighting fixture 30 included in the group 2 when the switch 40a according to the present embodiment is pressed, and FIG. 8A (c) shows the switch 40a according to the present embodiment. It is a figure which shows the lighting state of the luminaire 30 included in group 3 when it is pressed.

Further, as shown in FIG. 2, the group corresponding to the switch 40a is group 1, the scene information or slide show information is scene information 1, and the time information is 30 minutes. Group 1 includes luminaires 30a and 30b. The switch 40a is assigned to light the lighting fixtures 30a and 30b included in the group 1 for 30 minutes in the lighting state indicated by the scene information 1.

As shown in FIG. 8A (a), when the switch 40a is pressed, the lighting fixtures 30 (lighting fixtures 30a and 30b in the present embodiment) included in the group 1 corresponding to the switch 40a are turned on. The state is controlled to the lighting state corresponding to the switch 40a. In the present embodiment, it is controlled by the scene information 1. That is, when the detection unit 21 detects the operation of the switch 40a while reproducing the lighting state indicated by the schedule information, the control unit 22 corresponds to the switch 40a in preference to the reproduction of the lighting state indicated by the schedule information. The lighting state indicated by the lighting information C is controlled to be reproduced by the lighting fixture 30 included in the group indicated by the group information included in the lighting information C. In other words, the control unit 22 performs the first control in preference to the second control.

The luminaires 30 included in the groups 2 and 3 which are not the groups corresponding to the switch 40a (in the present embodiment, the luminaires 30c and 30d are included in the group 2 and the luminaires 30e and 30f are included in the group 3). ), The lighting state has not been changed. In other words, the lighting fixtures 30 included in the group 2 and the group 3 are lit in the lighting state indicated by the schedule information even when the switch 40a is pressed. That is, when the switch unit 40 is pressed, it is possible to control the lighting state of only the lighting fixture 30 included in the group associated with the switch unit 40 in advance. Therefore, the user can produce only a predetermined range of the space illuminated by the plurality of lighting fixtures 30 included in the lighting system 10.

Next, a case where the switch 40b is pressed while the schedule information is lit will be described with reference to FIG. 8B.

FIG. 8B is a diagram showing a lighting state of the lighting fixture 30 for each group when the switch 40b according to the present embodiment is pressed. Specifically, FIG. 8B (a) is a diagram showing a lighting state of the lighting fixture 30 included in Group 1 when the switch 40b according to the present embodiment is pressed, and FIG. 8B (b) is a diagram. Is a diagram showing a lighting state of the lighting fixture 30 included in the group 2 when the switch 40b according to the present embodiment is pressed, and FIG. 8B (c) shows the switch 40b according to the present embodiment. It is a figure which shows the lighting state of the luminaire 30 included in group 3 when it is pressed.

As shown in FIG. 8B (b), when the switch 40b is pressed, the lighting fixtures 30 (lighting fixtures 30c and 30d in the present embodiment) included in the group 2 corresponding to the switch 40b are turned on. The state is controlled to the lighting state corresponding to the switch 40b. In the present embodiment, it is controlled by the scene information 2. The luminaires 30 included in the groups 1 and 3 which are not the groups corresponding to the switch 40b (in the present embodiment, the luminaires 30a and 30b are included in the group 1 and the luminaires 30e and 30f are included in the group 3). ), The lighting state has not been changed. In other words, the lighting fixtures 30 included in the group 1 and the group 3 are lit in the lighting state indicated by the schedule information even when the switch 40b is pressed.

As shown above, in step S150, the lighting fixture 30 included in the group corresponding to the switch detected by the detection unit 21 is controlled to the lighting state corresponding to the switch. Further, as described above, the lighting information C according to the present embodiment includes repetitive information or time information. As shown in FIG. 2, the time information corresponding to the switch 40a is 30 minutes, and the time information corresponding to the switch 40b is 60 minutes. That is, the time for lighting in the lighting state indicated by the lighting information C is predetermined. Therefore, the control unit 22 controls the predetermined lighting fixture 30 to the lighting state indicated by the lighting information C in step S150, and then determines whether or not the predetermined number of repetitions or the predetermined time has been reached (S160). The predetermined number of repetitions or the predetermined time is the repetition information or time information included in the lighting information C.

When the predetermined number of repetitions or the predetermined time is reached (Yes in S160), the control unit 22 controls the lighting state of the predetermined group to the lighting state based on the schedule information (S170). As a result, all of the lighting fixtures 30 included in the lighting system 10 are lit in the same lighting state (for example, the lighting state indicated by the schedule information).

In other words, when the detection unit 21 detects an operation from the switch unit 40, the control unit 22 has scene information (first) corresponding to the switch unit 40 until the time indicated by the time information or the number of repetitions indicated by the repetition information is reached. Control is performed so that the lighting fixture 30 reproduces the lighting state indicated by the scene information) or the slide show information (an example of the first slide show information).

Here, as an example, a case where the switch 40a and the switch 40b are pressed while the schedule information of FIG. 5 is lit will be described with reference to FIGS. 8A and 8B.

As shown in FIG. 8A (a), the control unit 22 includes the illumination included in the group 1 with the scene information 1 corresponding to the switch 40a only for 30 minutes, which is the time information corresponding to the switch 40a after the switch 40a is pressed. Control the appliance 30. Then, when 30 minutes have passed, the control unit 22 ends the control due to the pressing of the switch 40a, and performs the control based on the schedule information as before the switch 40a is pressed. That is, the user does not have to press the switch 40a when terminating the control corresponding to the switch 40a.

For example, when the switch 40a is pressed at 12:30, the control unit 22 controls the lighting fixture 30 included in the group 1 to the lighting state indicated by the scene information 1 from 12:30 to 13:00 after 30 minutes. do. Then, when the control unit 22 reaches 13:00, the control unit 22 automatically switches from the control based on the scene information 1 to the control based on the schedule information (without any human operation).

Further, as shown in FIG. 8B (b), the control unit 22 includes the scene information 2 corresponding to the switch 40b in the group 2 only for 60 minutes, which is the time information corresponding to the switch 40a after the switch 40b is pressed. Controls the lighting fixture 30. Then, when 60 minutes have passed, the control unit 22 ends the control due to the pressing of the switch 40b, and performs the control based on the schedule information as before the switch 40b is pressed. That is, the user does not have to press the switch 40b when terminating the control corresponding to the switch 40b.

For example, when the switch 40b is pressed at 17:30, the control unit 22 displays the lighting fixture 30 included in the group 2 in the lighting state indicated by the scene information 2 from 17:30 to 18:30 60 minutes later. To control. Then, when the control unit 22 reaches 18:30, the control unit 22 automatically switches from the control based on the scene information 2 to the control based on the schedule information (without any human operation).

As shown in (a) of FIG. 8B and (b) of FIG. 8B, when the switch 40b is pressed and controlled by the scene information 2, the scene information to be reproduced is switched in the schedule information. Specifically, at 18:00, the scene reproduced from the scene information 3 to the scene information 4 is switched. Even in this case, the control unit 22 gives priority to the reproduction of the scene information after switching (in (a) of FIG. 8B, the scene information 4), and gives priority to the reproduction of the lighting information C corresponding to the switch 40b ((in FIG. 8B). In b), the lighting fixture 30 is controlled to reproduce the lighting state indicated by the scene information 2).

In the lighting system 10 according to the present embodiment, by operating the switch unit 40, the lighting fixture 30 included in the group corresponding to the switch unit 40 is lit in the lit state corresponding to the switch unit 40. It is continued only for the time corresponding to the switch unit 40 or the number of repetitions, and is automatically terminated when the time or the number of repetitions is reached. That is, the user can control the start and end of lighting in the lighting state corresponding to the switch unit 40 only by operating the switch unit 40 (for example, pressing it once).

For example, if the lighting information does not include repetitive information or time information, the luminaire can be controlled to the lighting state corresponding to the switch unit by operating the switch unit, but to end the control of the lighting state again. It was necessary to operate the switch section. That is, it is necessary to operate the switch unit when starting the control of the predetermined lighting state and when ending the control. On the other hand, in the lighting system 10 according to the present embodiment, since the lighting information C includes repetitive information or time information, the start and end of the lighting state can be controlled by one operation of the switch unit 40.

The predetermined time may be measured by, for example, the control unit 22 or the timer unit 23. Further, the predetermined number of repetitions may be measured by, for example, the control unit 22.

In the above description, an example in which the switch unit 40 is pressed while the lighting fixture 30 reproduces the lighting state shown in the schedule information has been described, but the present invention is not limited to this. For example, the switch unit 40 may be pressed when the luminaire 30 is not lit based on the schedule information, for example, when the luminaire 30 is off. In this case, the control unit 22 continues the lighting state indicated by the lighting information C after the switch unit 40 is pressed until the time indicated by the lighting information C or the number of repetitions is reached, and reaches the time indicated by the lighting information C or the number of repetitions. After reaching the limit, the lighting fixture 30 may be controlled to be turned off.

[4. Effect etc.]
As described above, the lighting control device 20 is a lighting control device 20 that controls the lighting state of the lighting fixture 30 based on the control information transmitted from the terminal device 50, and remotely controls the lighting state of the lighting fixture 30. A detection unit 21 that detects an operation from a switch unit 40 (an example of a remote operation unit), a control unit 22 that controls the lighting state of the lighting fixture 30 based on the detection result of the detection unit 21 and control information, and a control unit 22. To be equipped. The control information includes scene information (an example of the first scene information) indicating the lighting state of the lighting fixture 30 corresponding to the switch unit 40 and slide show information (an example of the first slide show information) in which two or more scene informations are combined. At least one of the above, and one of the time information and the repetition information regarding the reproduction of the lighting state indicated by at least one of the scene information and the slide show information are included, and the control unit 22 has the detection unit 21 from the switch unit 40. When an operation is detected, the lighting fixture 30 reproduces the lighting state indicated by at least one of the scene information and the slide show information corresponding to the switch unit 40 until the time indicated by the time information or the number of repetitions indicated by the repetition information is reached (No. 1). An example of the control of 1) is performed.

As a result, when the detection unit 21 detects the operation of the switch unit 40, the control unit 22 causes the lighting fixture 30 to reproduce the lighting state indicated by the scene information or the slide show information included in the control information (lighting information C). The reproduction is performed only until the time indicated by the time information included in the control information or the number of repetitions indicated by the repetition information is reached. That is, the reproduction is automatically terminated when the time or the number of repetitions is reached. The user can control the start and end of reproduction of the scene information or slide show information corresponding to the switch unit 40 only by operating the switch unit 40 once (for example, pressing the switch unit 40 once). In other words, the user does not have to operate the switch unit 40 again when the lighting state indicated by the scene information or the slide show information corresponding to the switch unit 40 is terminated. Therefore, according to the lighting control device 20, it is possible to improve the convenience when the lighting state of the lighting fixture 30 is controlled by using the switch unit 40.

Further, the time information includes scene information (an example of the first scene information) and slide show information (an example of the first slide show information) after the detection unit 21 detects an operation from the switch unit 40 (an example of the remote operation unit). It includes a duration for continuously reproducing the lighting state indicated by at least one, or an end time for ending the reproduction of the lighting state indicated by at least one of the scene information and the slide show information.

Thereby, the user can set the time information suitable for the user's intention among the duration for continuously reproducing the lighting state or the end time for ending the reproduction of the lighting state as the time information. That is, the convenience can be further improved.

Further, the control information includes at least one of scene information (an example of the second scene information) and slide show information (an example of the second slide show information) in which two or more scene informations are combined, and the scene information and the slide show information. Schedule information associated with time information relating to the reproduction of the lighting state indicated by at least one is included. Then, when the control unit 22 controls the lighting fixture 30 to reproduce the lighting state indicated by the schedule information (an example of the second control), the detection unit 21 controls the switch unit 40 (an example of the remote control unit). When the operation from is detected, the scene information (an example of the first scene information) and the slide show information (the first slide show information) corresponding to the switch unit 40 are prioritized over the control to reproduce the lighting state indicated by the schedule information. Control is performed so that the lighting fixture 30 reproduces the lighting state indicated by at least one of (one example).

As a result, when the switch unit 40 is operated while the lighting fixture 30 reproduces the lighting state shown in the schedule information, the lighting state indicated by the scene information or slide show information corresponding to the switch unit 40 is preferentially reproduced. Will be done. That is, even when the lighting fixture 30 is lit based on the schedule information, the user can reproduce the lighting state intended by the user by operating the switch unit 40.

Further, as described above, the lighting system 10 includes a terminal device 50, a lighting fixture 30, and a lighting control device 20 that controls a lighting state of the lighting fixture 30 based on control information transmitted from the terminal device 50. To be equipped.

As a result, when the detection unit 21 of the lighting control device 20 detects the operation of the switch unit 40, the control unit 22 causes the lighting equipment 30 to display the lighting state indicated by the scene information or slide show information included in the control information (lighting information C). The reproduction is performed only until the time indicated by the time information included in the control information or the number of repetitions indicated by the repetition information is reached. That is, the reproduction is automatically terminated when the time or the number of repetitions is reached. The user can control the start and end of reproduction of the scene information or slide show information corresponding to the switch unit 40 only by operating the switch unit 40 once (for example, pressing the switch unit 40 once). In other words, the user does not have to operate the switch unit 40 again when the lighting state indicated by the scene information or the slide show information corresponding to the switch unit 40 is terminated. Therefore, according to the lighting system 10, it is possible to improve the convenience when the lighting state of the lighting fixture 30 is controlled by using the switch unit 40.

Further, the lighting system 10 includes a plurality of lighting fixtures 30, and the plurality of lighting fixtures 30 are grouped into two or more groups in advance by the terminal device 50, and the control information includes the switch unit 40 (remote operation unit). (Example) includes information about a group whose lighting state is to be operated, and when the detection unit 21 detects an operation from the switch unit 40, the control unit 22 indicates information about the group included in the control information. The lighting state of the lighting fixture 30 included in the group is controlled.

As a result, when the lighting system 10 includes a plurality of lighting fixtures 30, the switch unit 40 operates the lighting state of only the lighting fixture 30 included in the group information included in the control information of the plurality of lighting fixtures 30. It can be controlled by. That is, since only a predetermined space among the spaces illuminated by the plurality of lighting fixtures 30 can be illuminated in the lighting state indicated by the control information, the effect of producing the space is improved.

(Other embodiments)
Although the lighting control device according to the embodiment and the lighting system including the lighting control device have been described above, the present invention is not limited to the above-described embodiment.

For example, in the above embodiment, the lighting control device is realized as a device separate from the lighting fixture, but the lighting control device may be built in the lighting fixture. That is, it may be realized as a part of a lighting fixture.

Further, in the above embodiment, an example in which a plurality of lighting fixtures included in the lighting system have the same configuration has been described, but the present invention is not limited to this. The configurations of the plurality of luminaires provided in the lighting system may be different. For example, although the plurality of luminaires described in the embodiment do not have a wireless communication unit, some or all of the plurality of luminaires described in the embodiment have wireless communication. It may have a part.

Further, in the above embodiment, an example in which the lighting information includes information about the group has been described, but the present invention is not limited to this. For example, when the lighting system has one luminaire, or when all the luminaires included in the lighting system are collectively controlled, the lighting information does not have to include information about the group. That is, when the operation of the switch unit is detected, the lighting control device may collectively control the lighting fixtures included in the lighting system.
