The lighting control device 100 includes a display terminal 80 such as a liquid crystal display and a touch panel with reference to FIG. 19 (a) described later. The display terminal 80 is connected to the control device 102 (FIG. 1) of the lighting control device 100 and displays the arrangement state of the plurality of lighting fixtures 11b. The lighting control device 100 transmits a switch control signal for controlling the opening and closing of the switch 50e to the plurality of lighting fixtures 11b.

The plurality of lighting fixtures 11b are arranged side by side in the horizontal direction as shown on the screen of the display terminal 80 of FIG. Then, in the plurality of lighting fixtures 11b, ID numbers as identification numbers are set in order from one end (left end in FIG. 19) of the plurality of lighting fixtures 11b to 001,002 ... 006. Further, the lighting side control unit 77 (FIG. 17) of each lighting fixture 11b wirelessly transmits information on the received signal intensity of the first wireless communication unit 42 to the control device 102 of the lighting control device 100. The control device 102 receives the information. Then, when the received signal strength is equal to or less than a preset value, the control device 102 switches the switch 50e of the lighting fixture 11b having a low received signal strength to open / close as necessary. To send.

The control process on the lighting control device 100 side and the lighting fixture 11b side will be described in detail with reference to FIG. The control on the lighting control device 100 side is executed by the control device 102, and the control on the lighting fixture 11b side is executed by the lighting side control unit 77 of the first wireless communication unit 42. First, on the lighting control device 100 side, in step S1, the control device 102 causes the display terminal 80 to display the layout drawing of the lighting fixture 11b. Then, in step S2, in response to the operation of instructing the light emitting state of the luminaire 11b by the operation unit 101 (FIG. 1), the control device 102 transmits a light source control signal for controlling the light emitting state to the luminaire 11b. Then, the process proceeds to step S3.

On the other hand, on the lighting fixture 11b side, when the power supply to the lighting fixture 11b is started in step S10, the lighting operation is started by the initial setting. Next, in step S11, it is determined whether or not a control signal has been received from the lighting control device 100. If the determination result in step S11 is negative (No), the determination process is repeated. On the other hand, if the determination result in step S11 is affirmative (Yes), the process proceeds to step S12, and the control in the illumination side control unit 77 is changed based on the control signal. Then, in step S13, the information of the control result is wirelessly transmitted to the control device 102 of the lighting control device 100. At this time, the information of the control result also includes the information of the received signal strength of the first wireless communication unit 42. After the process of step S13, the process returns to step S11.

On the lighting control device 100 side, in step S3, it is determined whether or not the control result information is received from the lighting device 11b side. If the determination result in step S3 is negative (No), the process proceeds to step S4, and it is determined whether or not the reception time is equal to or longer than the preset set time. If the determination result in step S4 is negative, the process returns to step S3. If the determination result in step S4 is affirmative, the process returns to step S2 and the process of transmitting the light source control signal to the luminaire 11b is performed again.

On the other hand, if the determination result in step S3 is affirmative (Yes), the process proceeds to step S5, and it is determined whether or not the received signal intensity in the luminaire 11b is equal to or less than the preset set value, and the determination result is negative. Then, the process returns to step S1. If the determination result in step S5 is affirmative, in step S6, it is determined whether or not the reception signal strength is improved by switching the opening / closing of the switch 50e. For example, if the lighting control device 100 has already transmitted the control signal for switching the opening / closing of the switch 50e, it is determined that the received signal strength does not improve even if the switching is performed again. If the determination result in step S6 is affirmative (Yes), in step S7, the control device 102 transmits a switch control signal instructing the switching of opening / closing of the switch 50e to the lighting fixture 11b, and then returns to step S1. .. If the determination result in step S6 is negative (No), the process returns to step S1.

When the switch control signal is transmitted from the lighting control device 100, the switch 50e is controlled on the lighting device 11b side in step S12 so as to switch the opening and closing of the switch 50e according to the control signal. As a result, in the configuration of this example, when the received signal strength of the luminaire 11b is low, the opening / closing of the switch 50e is automatically switched as needed. Other configurations and operations are the same as those in FIG.

FIG. 19 is a diagram showing two examples of display states of the display terminal 80 constituting another example lighting system of the embodiment. FIG. 20 is a flowchart showing a control method of the light source unit 40 and the switch 50e executed on the lighting control device 100 side in another example lighting system of the embodiment.

In the configuration described with reference to FIG. 18 above, when the received signal strength of the luminaire 11b is low, the opening and closing of the switch is automatically switched as necessary. On the other hand, in the configuration of this example, the contractor or the user gives an instruction to switch the switch on the lighting control device 100, and the switch of the lighting fixture 11b is switched accordingly.

Then, as shown in FIG. 19A, an image showing the arrangement of the lighting fixture 11b is displayed on the display terminal 80. Further, as shown in FIG. 19B, the control device 102 of the lighting control device 100 causes the display terminal 80 to display the information when the received signal intensity of the lighting device 11b is equal to or less than the set value. At the same time, the control device 102 displays an inquiry on the display terminal 80 as an inquiry as to whether or not to instruct the contractor or the user to open or close the switch of the lighting fixture 11b, and whether or not to switch the wireless operation. Let me. Further, the display terminal 80 is configured so that the information of the switch transmitted from at least one of the plurality of lighting fixtures 11b can be displayed on the display terminal 80 via the control device 102.

The control process on the lighting control device 100 side will be described with reference to FIG. In this example, the control on the lighting fixture 11b side is the same as the configuration described with reference to the flowchart of FIG. In the control process on the lighting control device 100 side, the processes of steps S21 to S25 are the same as the processes of steps S1 to S5 of FIG. In the determination in step S25, it is determined whether or not the received signal intensity in the luminaire 11b is equal to or less than the preset set value, and if the determination result is negative (No), the process returns to step S21. If the determination result in step S25 is affirmative (Yes), in step S26, the control device 102 causes the display terminal 80 to display the received signal status. The display state of the display terminal 80 at this time is, for example, the state shown in FIG. 19B. In FIG. 19B, "The wireless signal of ID001 is weak. Do you want to switch the wireless operation?" Is displayed, and "YES" and "NO" instruction input units are displayed. As a result, the display terminal 80 displays the information of the switch transmitted from the lighting fixture 11b having a low received signal strength. At this time, a touch panel is provided on the surface of the display terminal 80, and the contractor or the user touches either "YES" or "NO" of the instruction input unit with a finger to make a corresponding selection. At this time, the display terminal 80 also has a function as an operation unit.

Then, in step S27, the control device 102 determines whether or not the user has input a switching instruction for wireless operation. If the determination result in step S27 is negative (No), the process returns to step S21. If the determination result in step S27 is affirmative (Yes), in step S28, the control device 102 causes the luminaire 11b to transmit a switch control signal instructing the switch 50e (FIG. 17) to switch between opening and closing. .. Then, as described in S11 to S13 of FIG. 18, when the switch control signal is received on the luminaire 11b side, the switch 50e is controlled so as to switch the opening and closing of the switch 50e as a control change accordingly. Will be done. As a result, in the configuration of this example, when the received signal intensity of the luminaire 11b is low, the switch 50e is switched between opening and closing according to the selection of the luminaire control device 100 by the contractor or the user. Other configurations and operations are the same as those of FIG. 17 or FIG.
