ILLUMINATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an illumination control device capable of collectively, properly and easily controlling a light dimming degree of respective luminaires by simplifying the wiring connection of a light dimming signal wiring system derived from externally operable light dimming means when controlling light dimming of a lighting system constituted by continuously connecting a plurality of luminaires to one power source wiring system. SOLUTION: This illumination control device is composed of the lighting system by continuously connecting the plurality of luminaires 20 to one power source wiring system 22, and is constituted so as to collectively control the light dimming degree of the respective luminaires. The illumination control device is provided with a means 30 for respectively measuring a system current value It to the respective luminaires in the power source wiring system, and the light dimming means 26 and 27 for respectively dimming the light of the respective luminaires, and is constituted for controlling the light dimming degree so that a current value Ip flowing in the respective luminairs respectively keeps the system currerst value It of the corresponding power source wiring system and the prescribed ratio (a factor K).
