(Embodiment)
[Overall configuration of lighting system]
First, the overall configuration of lighting system 100 according to the present embodiment will be described. FIG. 1 is a diagram showing a configuration example of a lighting system 100 according to this embodiment.

The lighting system 100 includes a plurality of lighting fixtures 10a to 10f, sensors 20a and 20b, a setting device 30, and a controller 40.

The plurality of lighting fixtures 10a to 10f are installed, for example, on the floor ceiling or the like, receive control signals transmitted wirelessly or by wire from the sensors 20a and 20b, and operate according to the received control signals. For example, the control signal includes instructions such as turning on, turning off, dimming, or toning. Further, each of the plurality of lighting fixtures 10a to 10f has an identification number such as an individually identifiable address. can be operated with different control signals. Although six lighting fixtures 10a to 10f are shown in FIG. 1, this figure is an example, and more than 100 lighting fixtures may actually be installed.

A plurality of lighting fixtures 10a to 10f are divided into a plurality of groups 200a and 200b whose members are lighting fixtures to perform a common lighting operation. In other words, a group is a unit of lighting fixtures that should perform the same lighting operation. In FIG. 1, a plurality of lighting fixtures 10a, 10b, 10c, and 10f belong to group 200a, and a plurality of lighting fixtures 10d and 10e belong to group 200b. For example, a group is a collection of lighting fixtures belonging to the same room, same department, same department, same classroom, or same block. Although two groups 200a and 200b are shown in FIG. 1, this figure is an example, and the number of groups is not limited and is set as required. Also, the number of lighting fixtures belonging to a group may be one or plural.

The sensors 20a, 20b are used by the controller 40 to control the lighting operation of the plurality of lighting fixtures 10a-10f. Sensors 20a, 20b are assigned to a plurality of lighting fixtures 10a-10f. The sensors 20a and 20b are, for example, sensors that are provided on the floor ceiling or the like and detect information on the detection range. The sensors 20a and 20b may be used for the plurality of lighting fixtures 10a to 10f based on the detected information, and there is no particular limitation on the types of sensors. Sensors 20a and 20b may be brightness sensors that detect brightness. The brightness sensor may have a function other than detecting brightness as long as it has a function of detecting brightness. Moreover, the sensors 20a and 20b may be human sensors that detect whether or not a person exists within the detection range. The human sensor may have a function other than detecting the presence of a person as long as it has a function of detecting the presence of a person. As the sensors used for the sensors 20a and 20b, the same sensor may be used, or sensors with different detection targets may be used in combination. The sensors 20 a and 20 b transmit their detection results to the controller 40 .

For example, if the sensors 20a and 20b are brightness sensors, the sensors 20a and 20b are installed around the location where the lighting fixtures 10a to 10f to which one of the sensors is assigned are installed. The brightness sensor detects the brightness of the lighting fixture by detecting the illuminance of the floor or the like illuminated by the lighting fixture to which the sensor is assigned. A detection result is transmitted to the controller 40 . For example, the controller 40 controls dimming of the lighting fixture to which the sensor is assigned so that the brightness detected by the sensor reaches a predetermined set value. Specifically, when the detected brightness is brighter than a predetermined brightness setting value, the dimming rate of the lighting fixture to which the sensor is assigned is lowered. Increases the dimming rate of assigned lighting fixtures. The predetermined brightness setting value is stored, for example, in the controller 40, and the controller 40 compares the detected brightness with the predetermined brightness setting value stored in the controller 40. , performs dimming control of the lighting fixture to which the sensor is assigned. As a result, the floor or the like on which the lighting equipment is provided can be made to have desired brightness.

Further, for example, when the sensors 20a and 20b are human sensors, the sensors 20a and 20b are installed around the place where the lighting fixtures 10a to 10f to which one of the sensors is assigned are installed. The human sensor detects infrared rays or the like around the lighting fixture to which the sensor is assigned, and detects whether or not a person exists within the detection range. A detection result is transmitted to the controller 40 . For example, the controller 40 controls the lighting fixture to which the sensor is assigned to light only when the presence of a person is detected by the sensor. As a result, the light is turned off when no one is present, so the amount of electricity used can be reduced.

Furthermore, the sensors 20a and 20b each have a wireless communication function or a wired communication function, and the controller 40 and the plurality of lighting fixtures 10a to 10f can communicate via the sensors 20a and 20b. The lighting fixtures communicated via the sensors 20a and 20b and the lighting fixtures controlled by the detection results of the sensors 20a and 20b may not match. As a communication system by wireless communication, for example, a system such as a specified low-power radio using a frequency of 920 MHz band or 2.4 GHz band, Zigbee (registered trademark), Bluetooth (registered trademark), or WiFi (registered trademark). Used. Although two sensors 20a, 20b are shown in FIG. 1, this figure is an example, and in practice one or more sensors may be installed.

The setter 30 is operated to assign the sensors 20a, 20b used by the controller 40 to control the plurality of lighting fixtures 10a-10f to the plurality of lighting fixtures 10a-10f. The setting device 30 is, for example, a mobile terminal such as a smartphone and a tablet, a personal computer, or the like, and communicates with the controller 40 by wireless communication. The setting device 30 divides the plurality of lighting fixtures 10a to 10f into a plurality of groups, assigns one of the sensors 20a and 20b to at least one of the plurality of groups, and groups the plurality of lighting fixtures 10a to 10f. , etc. The setting device 30 may receive lighting schedule information that determines the control method for each time slot. The setting device 30 transmits the received information to the controller 40 .

The controller 40 controls lighting operations of the plurality of lighting fixtures 10a-10f. Specifically, the controller 40 transmits control signals for controlling lighting operations to the plurality of lighting fixtures 10a to 10f via the sensors 20a and 20b. The controller 40 also receives the detection results of the sensors 20a and 20b. The controller 40 transmits control signals to the plurality of lighting fixtures 10a-10f based on the information transmitted by the setting device 30 and the detection results. For example, when the sensor 20a is assigned to the group 200a, the controller 40 controls the lighting fixtures 10a, 10b, 10c, and 10f belonging to the group 200a based on the sensor 20a. Moreover, when the sensor 20b is assigned to the group 200b, the controller 40 controls the plurality of lighting fixtures 10d and 10e belonging to the group 200b based on the sensor 20b.

In addition, the controller 40 controls the first mode collectively controlling the plurality of lighting fixtures 10a to 10f for each group according to the operation of the setting device 30, and the lighting fixtures 10a to 10f to which the lighting fixtures belong. It may have a second mode of control based on the detection results of the sensors assigned to the group. In the first mode, the lighting fixtures 10a to 10f are controlled based on the lighting operation (turning on, turning off, dimming rate, color temperature, etc.) of each group received by the setting device 30, for example. Alternatively, the setting device 30 may switch between the first mode and the second mode for each time by receiving a lighting schedule that associates times and lighting operations for each group. As a result, it is possible to incorporate control that is not based on the detection result of the sensor even for lighting fixtures to which sensors are assigned.

[Each configuration of the lighting system]
Next, each configuration of the lighting system 100 will be described. FIG. 2 is a block diagram showing the control configuration of lighting fixture 10, sensor 20, setting device 30, and controller 40 that constitute lighting system 100. As shown in FIG. The luminaire 10 is a representative example of the plurality of luminaires 10a to 10f shown in FIG. 1, and the sensor 20 is a representative example of the sensors 20a and 20b shown in FIG.

The lighting fixture 10 includes a light source unit 11, a lighting circuit 12, a control circuit 13, a communication section 14, a storage section 15, and a power supply circuit 16, as shown in FIG.

The light source unit 11 has a light source and emits illumination light. Examples of light sources include LEDs (Light Emitting Diodes), fluorescent lamps, and incandescent lamps.

The lighting circuit 12 supplies power to the light source unit 11 to light the light source unit 11 .

The control circuit 13 controls the lighting operation of the lighting fixture 10 by controlling the lighting circuit 12 . The control circuit 13 includes, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The control circuit 13 controls lighting, extinguishing, dimming, or toning of the light source unit 11 as lighting operations according to the control signal received by the communication unit 14 .

The communication unit 14 receives the control signal transmitted from the sensor 20 via the wired communication path, and notifies the control circuit 13 of the received control signal. The communication unit 14 also transmits a response signal notified from the control circuit 13 to the sensor 20 . The communication unit 14 is configured by, for example, a wired communication interface such as a LAN (Local Area Network). Note that the communication unit 14 may use wireless communication instead of wired communication.

Here, an example of how control signals are handled in the lighting device 10 will be described. A control signal includes a destination address, a source address and a command. The address of the lighting device 10 is set as the destination address of the control signal transmitted from the sensor 20 to the lighting device 10, and the address of the sensor 20 is set as the source address.

The destination address is handled as follows, for example. The control circuit 13 controls the lighting circuit 12 according to the control signal when the transmission destination address of the control signal notified from the communication unit 14 corresponds to its own address (that is, the address of the lighting device 10). Conversely, when the transmission destination address of the control signal notified from the communication unit 14 does not correspond to its own address, the control circuit 13 discards the control signal without performing control according to the control signal.

For example, the source address is handled as follows. The control circuit 13 controls the lighting circuit 12 according to the control signal when the transmission source address of the control signal notified from the communication unit 14 corresponds to the address of the communication partner (the address of the sensor 20). Conversely, when the transmission source address of the control signal notified from the communication unit 14 does not correspond to the address of the communication partner, the control circuit 13 discards the control signal without performing control according to the control signal.

Also, the command included in the control signal is a signal that instructs the lighting operation of the lighting fixture 10, and for example, instructs lighting, extinguishing, dimming, or toning.

The storage unit 15 stores the identification information and the control signal received by the communication unit 14 . The identification information is, for example, the address of the lighting device 10 itself, and the address of the sensor 20 as information indicating the communication partner. The storage unit 15 is configured by, for example, RAM and ROM. The identification information can be set by the setting device 30, for example.

The power supply circuit 16 is, for example, a power supply for AC-DC conversion, and supplies power to each part of the lighting fixture 10 .

The plurality of lighting fixtures 10 in the lighting system 100 may have the same specifications, or may include lighting fixtures 10 with different specifications.

Also, the control circuit 13 may be a microcomputer containing a memory storing a program and a microprocessor, or may be hardware including an analog circuit and a digital circuit.

The sensor 20 includes a control section 21, a detection section 22, a communication section 23 and a storage section 24, as shown in FIG.

The control unit 21 performs control for relaying control signals and response signals between the controller 40 and the lighting fixture 10 . The control unit 21 is composed of, for example, a CPU, a RAM, and a ROM.

The detection unit 22 detects information on the detection range. For example, the detection unit 22 includes an illuminance meter for detecting ambient brightness, an infrared detector and a sound detector for detecting whether a person is present, and the like.

The communication unit 23 receives a control signal directed to the lighting fixture 10 from the controller 40 via the wired communication path, and transmits the control signal to the lighting fixture 10 . The communication unit 23 also transmits the response signal of the lighting device 10 and the detection result of the detection unit 22 to the controller 40 . The communication unit 23 is configured by, for example, a wired communication interface such as a LAN. Note that the communication unit 23 may use wireless communication instead of wired communication.

The storage unit 24 stores the identification information, the detection result of the detection unit 22, and the control signal received by the communication unit 23. FIG. The identification information includes, for example, the address of the sensor 20 itself, and the address of the lighting device 10 as information indicating the communication partner. The identification information can be set by the setting device 30, for example. The storage unit 24 is composed of, for example, a RAM and a ROM.

Note that the control unit 21 may be a microcomputer containing a memory storing a program and a microprocessor, or may be hardware including an analog circuit and a digital circuit.

Further, when there are a plurality of sensors 20, the sensors 20 may have the same specifications as to the type of information to be detected, or the sensors 20 may have different specifications.

The setting device 30 includes an operation reception unit 31, a processor 32, a storage unit 33, and a communication unit 34, as shown in FIG.

The operation accepting unit 31 accepts an operation of dividing the plurality of lighting fixtures 10 into a plurality of groups and an operation of assigning the sensor 20 to at least one of the plurality of groups. Further, the operation accepting unit 31 accepts an operation to change one group of the plurality of lighting fixtures 10 among the plurality of groups to which the assigned sensors 20 are different. In addition, the operation reception unit 31 may receive operation settings in the lighting system 100 such as the lighting operation of each group and the lighting schedule of each group. The lighting schedule, assigned sensors 20 and lighting operations can be defined for each group. The same sensor 20 may be assigned to two or more of the multiple groups. The operation reception unit 31 includes a touch panel 31a. The touch panel 31a allows the user to perform input, setting, etc. while confirming the display, so that the user can intuitively operate.

The processor 32 executes various programs stored in the storage unit 33 . For example, the processor 32 is configured with a CPU or the like.

The storage unit 33 stores various programs executed by the processor 32 and various data referred to or generated by the processor 32 . Further, the storage unit 33 stores operation results accepted by the operation accepting unit 31 . The storage unit 33 stores first information 33a indicating the group to which each of the plurality of lighting fixtures 10 belongs, and second information 33b indicating the sensor 20 assigned to at least one of the groups. The first information 33a is, for example, a data table showing the correspondence between each lighting fixture 10 and a group, as shown in FIG. 3A. The second information 33b is, for example, a data table showing the correspondence between groups and sensors 20, as shown in FIG. 3B. As shown in FIG. 3B, in the second information 33b, there may be cases where no sensor 20 is assigned to a group (area 01, zone 002), and even if the same sensor 20 is assigned to two or more groups. Good (zone 001 and zone 002 in area 02). As shown in FIGS. 3A and 3B, groups may be divided into layers, areas may be set as large groups, and zones may be further set within the areas. For example, by dividing the entire living room and the entire floor into areas, and further dividing the teams and shops in the living room and floor into zones, the control of the lighting becomes easier to manage. The storage unit 33 may also store information about operation settings in the lighting system 100, such as lighting operations for each group and lighting schedules for each group. The storage unit 33 is composed of, for example, a RAM and a ROM. Note that the storage unit 33 may include primary memory, secondary memory, auxiliary memory, and cache memory.

The communication unit 34 transmits to the controller 40 first information 33a indicating the group to which each of the plurality of lighting fixtures 10 belongs, and second information 33b indicating the sensor 20 assigned to at least one of the plurality of groups. Furthermore, the communication unit 34 transmits to the controller 40 the changed first information 33 a indicating the changed group of one of the plurality of lighting fixtures 10 . In this embodiment, the communication unit 34 is an example of a transmission unit. Further, the communication unit 34 may transmit lighting control information such as lighting operation information of each group and lighting schedule information of each group in the lighting system 100 to the controller 40 by the operation received by the operation receiving unit 31 . The communication unit 34 wirelessly communicates with the controller 40 via a wireless communication path. The communication unit 34 is composed of, for example, an antenna and a wireless module. Note that the communication unit 34 may use wired communication instead of wireless communication.

Note that the setting device 30 has shown an example configured based on a tablet-type terminal device, but may be configured based on a personal computer or a smartphone.

The controller 40 includes a storage section 41, a control section 42, a communication section 43 and a clock circuit 44, as shown in FIG.

The storage unit 41 stores the first information 41 a and the second information 41 b received by the communication unit 43 . Therefore, the first information 41a and the second information 41b are the same as the first information 33a and the second information 33b of the setting device 30 described above. Further, the storage unit 41 stores the changed first information 41a. Further, the storage unit 41 may store the lighting operation information of each group and the lighting schedule information of each group received by the communication unit 43 . The storage unit 41 is composed of, for example, a RAM and a ROM.

Based on the first information 41a and the second information 41b stored in the storage unit 41, the control unit 42 determines each of the plurality of lighting fixtures 10 based on the detection result of the sensor 20 assigned to the group to which the lighting fixture belongs. to control.

The clock circuit 44 counts the date and time and is referred to by the control unit 42 for control according to the lighting schedule information.

Note that the control unit 42 may be a microcomputer containing a memory storing a program and a microprocessor, or may be hardware including an analog circuit and a digital circuit.

[Method for assigning sensors to lighting fixtures]
Next, a method of allocating the sensor 20 according to the present embodiment to the lighting fixture 10 by operating the setting device 30 will be described.

The assignment method according to the present embodiment is a method of assigning at least one sensor 20 used by the controller 40 to control the plurality of lighting fixtures 10 to the plurality of lighting fixtures 10 by operating the setting device 30. . The assignment method consists of a first reception step in which the setter 30 receives an operation of dividing the plurality of lighting fixtures 10 into a plurality of groups, and a second reception step in which the setter 30 receives an operation of allocating the sensor 20 to at least one of the plurality of groups. 2 receiving step, the setting device 30 sends the first information 33a indicating the group to which each of the plurality of lighting fixtures 10 belongs and the second information 33b indicating the sensor assigned to at least one of the plurality of groups to the controller 40. and a first transmitting step of transmitting. Based on the received first information 33a and second information 33b, the controller 40 controls each of the plurality of lighting fixtures 10 based on the detection result of the sensor 20 assigned to the group to which the lighting fixture belongs.

FIG. 4A is a flowchart showing how the setter 30 assigns the sensors 20 to groups to which a plurality of lighting fixtures 10 belong in the assignment method according to the present embodiment. Also, FIG. 4B is a flowchart showing the processing of the controller 40 when the sensor 20 is assigned to the group to which the plurality of lighting fixtures 10 belongs in the assigning method according to the embodiment.

First, as shown in FIG. 4A, the setting device 30 receives an operation from the user to set a group for dividing a plurality of lighting fixtures 10 into a plurality of groups (S11). In the case of a commercial complex, for example, the user operates the touch panel 31a of the operation reception unit 31 to set an area for each floor and set a zone for each store. Next, the setting device 30 receives an operation for dividing each of the plurality of lighting fixtures 10 into the plurality of groups set in step S11 (S12). The information received by the operations in steps S11 and S12 is stored in the storage unit 33 as first information 33a indicating the group to which each of the plurality of lighting fixtures 10 belongs. The screen of the touch panel 31a in the setting device 30 after step S12 is completed is shown as shown in FIG. In FIG. 5, each lighting fixture 10 is indicated by an icon, and area and zone numbers are displayed above the icons as groups to which the lighting fixtures 10 belong. The horizontal number labeled A is the area number, and the horizontal number labeled Z is the zone number. By displaying the area number and zone number, the user can easily determine which group each lighting device 10 belongs to, simply by looking at the touch panel 31a.

Next, the setting device 30 accepts an operation for allocating the sensor 20 to one of the groups (S13). If there is a group to which the sensor 20 is to be assigned, that is, if the assignment of the sensor 20 has not been completed (No in S14), the sensor 20 is assigned to the group to which no sensor 20 has been assigned. Note that the same sensor 20 or different sensors 20 may be assigned to different groups. The information received by the operation of step S13 is stored in the storage unit 33 as second information 33b indicating the sensors 20 assigned to the multiple groups. In addition, it is not necessary to assign the sensors 20 to all groups, and groups to which the lighting fixtures 10 installed in places where control by the sensors 20 is not required may be controlled by separately set lighting operations or the like.

When the assignment of the sensor 20 to the group to which the sensor 20 is to be assigned is completed (Yes in S14), the setting device 30 sets the first information 33a indicating the group to which each of the plurality of lighting fixtures 10 belongs, and the plurality of groups to the controller 40 (S15). The setter 30 may assign information regarding lighting settings, such as lighting operation information and lighting schedule information, to groups and send the results to the controller 40 .

Next, as shown in FIG. 4B, the controller 40 receives the first information 33a and the second information 33b transmitted in step S15 in FIG. 4A (S16). In the controller 40, the received first information 33a and second information 33b are stored in the storage section 41 (S17). Based on the stored first information 41a and second information 41b, the controller 40 selects each of the plurality of lighting fixtures 10 based on the detection result of the sensor 20 assigned to the group to which the lighting fixture belongs. (S18).

FIG. 6A is a diagram showing an example of operation in setting device 30 when assigning sensors to a plurality of groups in the assigning method according to the present embodiment. (a) and (b) of FIG. 6A show the screen of the touch panel 31a of the setting device 30. FIG. As in FIG. 5, each lighting fixture 10 is indicated by an icon, and the number of the area and zone as the group to which the lighting fixture 10 belongs is displayed above the icon. 6B is an example of a screen of the touch panel 31a of the setting device 30 displayed when the sensor 20 is selected.

For the operation of assigning the sensor 20 to any one of the groups in step S13 of FIG. 4A, first, the lighting fixture 10 belonging to the group to which the sensor 20 is to be assigned is selected on the brightness sensor setting screen. Specifically, when the lighting fixture 10 on the screen of the touch panel 31a is touched, the display color is changed, so that it can be understood that it is selected (area 301). In the operation for allocating the sensor 20, even if any of the lighting fixtures 10 belonging to the same group is touched, all the lighting fixtures 10 belonging to the same group are selected. can be done.

Next, when the area 302 described as sensor pairing is touched, the sensor (light control adapter) selection screen shown in FIG. 6B is displayed. Sensor pairing refers to the operation of assigning sensors to groups. By touching the area 304 in FIG. 6B, the dimming adapter A1 is selected as the sensor. This operation assigns the sensor (dimmer adapter) A1 to the group of lighting fixtures 10 in area 301 in FIG. The fact that A1 has been selected as the sensor is displayed in parentheses above the 10 icons. In this way, by displaying the groups and sensors 20 above the icons of the lighting fixtures 10, the user can easily understand which group and which sensor 20 controls each lighting fixture 10 at a glance, making it easier to operate. .

Furthermore, in the assignment method according to the present embodiment, after the first transmission step, the setter 30 performs an operation to change one group of the plurality of lighting fixtures 10 between the plurality of groups to which the assigned sensors 20 are different. a third receiving step of receiving; and a second transmitting step of transmitting changed first information 33 a indicating a changed group of one of the plurality of lighting fixtures 10 to the controller 40 . Based on the received post-change first information 33a, the controller 40 assigns the lighting fixtures 10 whose group has been changed by the changing operation among the plurality of lighting fixtures 10 to the detection results of the sensors 20 assigned to the post-change group. control based on

FIG. 7A is a flow chart showing how the setting device 30 changes the grouping of the lighting fixtures 10 after step S15 in FIG. 5 in the assignment method according to the present embodiment. FIG. 7B is a flowchart showing the processing of the controller 40 when the grouping of the lighting fixtures 10 is changed in the allocation method according to this embodiment.

First, as shown in FIG. 7A, the setting device 30 receives an operation for selecting lighting fixtures 10 whose grouping is to be changed (S21). In step S21, one or a plurality of lighting fixtures 10 may be selected from a plurality of lighting fixtures 10 as the lighting fixtures 10 whose grouping is to be changed. When a plurality of lighting fixtures 10 are selected from a plurality of lighting fixtures 10, the selected lighting fixtures 10 may be selected from the same group or from different groups. That is, in step S21, it is possible to select lighting fixtures 10 whose grouping is to be changed regardless of the groups to which the plurality of lighting fixtures 10 belong. Next, the setting device 30 accepts selection of the changed group of the selected lighting fixture 10 (S22). The information received by the operations in steps S21 and S22 is stored in the storage unit 33 as the changed first information 33a indicating the changed group of the selected lighting fixture 10 . Then, the setting device 30 transmits the changed first information 33a indicating the group to which each of the plurality of lighting fixtures 10 is changed to the controller 40 (S23).

Next, as shown in FIG. 7B, the controller 40 receives the changed first information 33a indicating the changed group of the lighting fixtures 10 transmitted in step S23 in FIG. 7A (S24). In the controller 40, the received changed first information 33a is stored in the storage unit 41 (S25). In the stored second information 41b, if the sensor 20 differs before and after the group change of the lighting fixture 10 to which the belonging group has been changed (No in S26), the sensor 20 assigned to the lighting fixture 10 is changed (S27 ). The case where the sensors 20 are different means the case where the sensors 20 assigned to the groups before and after the change are different in the stored second information 41b, and the case where the sensor 20 is not assigned to one of the groups before and after the change. include. If the sensor 20 is not assigned to the group to which the lighting fixture 10 before the change belongs, the controller 40 newly assigns the sensor 20 to the lighting fixture 10 . If the sensor 20 is not assigned to the group to which the changed lighting fixture 10 belongs, the controller 40 cancels the assignment of the sensor 20 of the lighting fixture 10 .

In the stored second information 41b, if the sensor 20 is the same before and after the group change of the lighting fixture 10 to which the belonging group has been changed (Yes in S26), the sensor 20 assigned to the lighting fixture 10 is not changed (S28). . For example, when the same sensor 20 is assigned to different groups, the sensor 20 assigned to the lighting fixture 10 is not changed even if the group to which the lighting fixture 10 belongs is changed between the groups. Then, based on the changed first information 41a and second information 41b, the controller 40 controls the plurality of lighting fixtures 10 based on the detection results of the sensors 20 assigned to the changed group (S29). .

FIG. 8A is a diagram showing an example of the operation of setting device 30 when changing the grouping of lighting fixtures 10 in the assignment method according to the present embodiment. (a) and (b) of FIG. 8A show the screen of the touch panel 31a of the setting device 30. FIG. Similar to FIG. 6A , each lighting fixture 10 is indicated by an icon, and area numbers, zone numbers, and sensors 20 are assigned as groups to which the lighting fixtures 10 belong above the icons. number is displayed. FIG. 8B is an example of a screen of the touch panel 31a of the setting device 30 displayed when selecting a group.

In the operation of selecting lighting fixtures 10 whose grouping is to be changed in step S21 of FIG. 7A, first, the lighting fixtures 10 whose grouping is to be changed are selected on the zone setting screen. Specifically, when the lighting device 10 on the screen of the touch panel 31a is touched, the display color is changed, so that it can be understood that it is selected (area 305). In the operation of changing the grouping of lighting fixtures 10, one lighting fixture 10 or a plurality of lighting fixtures 10 may be selected. Further, when a plurality of lighting fixtures 10 are selected, lighting fixtures 10 belonging to the same group may be selected, or lighting fixtures 10 belonging to different groups may be selected. When selecting the lighting fixtures 10 belonging to the same group on the touch panel 31a, by touching one of the lighting fixtures 10 twice, all the lighting fixtures 10 belonging to the same group are selected. Accordingly, the group can be changed by an easy operation in both cases of individually changing the group of the lighting fixtures 10 belonging to the same group and collectively changing the group.

Next, when the area 306 labeled Change Zone is touched, the group (zone) change screen shown in FIG. 8B is displayed. The group is changed to zone 2 by touching the portion of area 308 in FIG. 8B. By this operation, the group of lighting fixtures 10 in area 305 in FIG. 8A(a) is changed to zone 2, and Z indicating the zone above the icon as shown in area 307 in FIG. 8A(b). The number on the side is changed to 002. Since sensor A2 was assigned to zone 2, simultaneously with the zone change, the numerical value in parentheses indicating sensor 20 is also changed to A2, and sensor A2 is assigned to lighting fixture 10 whose group has been changed.

Before step S15 in FIG. 4A, the setting device 30 sets the first mode for collectively controlling the plurality of lighting fixtures 10 for each group, and assigns each of the plurality of lighting fixtures 10 to the group to which the lighting fixture 10 belongs. You may accept the 2nd mode controlled based on the detection result of the sensor 20 assigned. For example, information about the first mode and the second mode are assigned to groups and sent to the controller 40 along with the lighting schedule information. Further, in step S18 of FIG. 4B, the controller 40 may control the plurality of lighting fixtures 10 based on the first mode and second mode assigned to the group. Further, the controller 40 may switch between the first mode and the second mode for each time according to lighting schedule information that associates times and lighting operations for each group.
