PURPOSE:To make it possible to obtain smoothly stabilized target illuminance by employing a light source lit with the output of a dimmer unit which controls the output according to the dimmer command signal outputted from an illuminance setting section thereby changing the amount of electric power in stages to the target value. CONSTITUTION:An illuminance setting section 7 for outputting a dimmer command signal, a signal transmitting section 8 for transmitting the dimmer command signal outputted from the illuminance setting section 7 through a wireless medium, and a power source 9 constituted with a storage battery, a solar cell or a commercial power source through an AC adaptor or the like are provided. A lighting equipment section 2 on the other hand is connected to a power source section 15 and provided with a reception control unit 16 for receiving the dimmer command signal set through the wireless medium and sent from the signal transmitting section 8, a dimmer unit 17 having a regulator or a dimmer circuit for regulating the light according to the dimmer command signal, and a light source 18 such as a fluorescent lamp or an incandescent lamp. Thus a target illuminance is obtained smoothly in a stabilized manner. |
