ILLUMINATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an illumination control device capable of stably controlling light output according to target illuminance set for every illumination system and easily installable in an existing illumination system.

SOLUTION: This illumination control device includes: a plurality of illumination systems G; a dimmer S0 with an illuminance sensor installed in a predetermined one of the illumination systems and having an illuminance sensor for controlling light modulation of the plurality of illumination systems; a plurality of child illuminance sensors S1 and S2 installed in the plurality of illumination systems other than the illumination system with the dimmer with an illumination sensor installed therein; and a dimming level setting means causing the dimmer with an illuminance sensor to set the dimming levels of the illumination systems at the average illuminance of the illuminance values detected by the respective illuminance sensors when the target illuminance of the illumination systems is identical and to set the dimming levels of the respective illumination systems by ratios of illuminance values detected by the respective illuminance sensors when the target illuminance values of the illumination systems are different from one another.
