ILLUMINATION CONTROL SYSTEM AND CONTROL SYSTEM

摘要

An illumination control system includes at least two illumination devices and at least one illuminance comparison device. The illuminance comparison device compares an illuminance at an arbitrary position with a target illuminance and the supplies the comparison result to the illumination devices. The at least two illumination devices make judgment according to the comparison result acquired from the illuminance comparison device and repeat increase/decrease of light intensity of the respective devices so as to control the illuminance at the arbitrary position almost to the target illuminance. By using this illumination control system, it is possible to control a predetermined position to a desired illuminance.
