As a result of the determination in step S105, when the event is on / off of power due to a power failure, the controller 70 determines that the illuminance value of the lamp is stored in the storage unit 60 when power is supplied to the lamp again. It is determined whether the illuminance value of (S115).

As a result of the determination in step S114, when the illuminance value of the lamp is not a predetermined illuminance value, the controller 70 controls the setting unit 40 so that the illuminance value of the lamp has a preset illuminance value. The illuminance value of the lamp is automatically returned to the previously set illuminance value (S116).

As a result of the determination in step 114, when the illuminance value of the lamp is a predetermined predetermined illuminance value, the controller 70 drives the driving unit 80 based on the illuminance value of the light stored in the storage unit 60. By turning on and off the lamp (S117).
