Moreover, the setting content of the lighting fixture 10 is memorize | stored previously. The stored data and the like are read into the signal processing unit 26 as appropriate.

The signal processing unit 26 obtains the strength of the received signal (latest signal strength) and stores it in the storage unit 25, and performs setting processing stored in the storage unit 25 based on the signal received by the reception unit 24. The power value to be sent to the light emitting unit 22 is determined and sent to the power supply control unit 27. In addition, the latest signal intensity and power value are transmitted to another lighting fixture 53 via the signal line 54 connected to the signal terminal 23. The signal processing unit 26 compares the latest signal intensity with the signal intensity of the other lighting fixtures 53 stored in the storage unit. When the latest signal intensity is strong, the infrared signal 31 from the remote controller 30 is It is determined that the lighting device 10 is directed.

Set the power value of the appliance 12 to 25%.

  On the other hand, when it is determined in step SA5 that the infrared signal 31 is not directed to the lighting apparatus 10 (step SA8), the remote control 30 is set according to a program that is set in advance and stored in the storage unit 25. The power value as a non-luminaire is determined (step SA9). For example, when it is determined that the infrared signal 31 is directed to the lighting fixture 11, the power value of the lighting fixture 10 is set to a predetermined maximum value of 50%, the power value of the lighting fixture 11 is set to 100%, and the signal strength is the weakest. The power value of the lighting fixture 12 is set to 25%.
