ILLUMINANCE CONTROL SYSTEM AND METHOD FOR MULTI CHANNEL LIGHTING

摘要

PURPOSE: A system and method for controlling the luminance of a multi-channel lighting are provided to control a three-phase AC power supply in one central processing unit by insulating an MCU control power and a lamp control power. CONSTITUTION: A system includes a lighting control device(100), a lighting group(200), a distribution panel(300) and a lighting control room(400). The lighting control device transmits an external luminance value obtained by using a luminance sensor to the lighting control room. The lighting group is composed of a plurality of lightings arranged in each channel. The distribution panel controls the lighting by being connected to each channel of the lighting control device. A wireless communication unit(120) communicates with the lighting control room. A central processing unit(170) controls the luminance of the lighting of the lighting group. The lighting control room monitors the operation condition of the lighting group.
