POWER SUPPLY CONTROLLER FOR LUMINAIRE, AND ILLUMINATION SYSTEM

PROBLEM TO BE SOLVED: To relatively easily add or change an LED lamp of an illumination system which includes a plurality of LED lamps and is configured to perform light control.SOLUTION: In the illumination system equipped with a power supply controller that outputs a current for driving a luminaire 11 and controls the current to control illuminance of the luminaire, a power supply controller 12 includes a receiver 24 capable of receiving a radio signal of a predetermined frequency, storage means for storing a setting table holding a predetermined apparatus identification code, a control signal generation circuit which outputs a control signal when a code included in the radio signal received by the receiver and the apparatus identification code held in the setting table are compared and match each other, and a current output circuit 20B which generates and outputs a current corresponding to the control signal. The illumination system is configured to control the luminance of the luminaire in response to a radio signal from a desired radio signal transmitter 14 by changing the apparatus identification code held in the setting table.
