DIMMING AND SWITCHING CONTROL SYSTEM FOR LIGHT-EMITTING DIODE LIGHTING APPARATUS

摘要

PURPOSE: A system for controlling the illuminance and switching of an LED lighting device is provided to reduce material costs and personnel expenses since separate telecommunication lines are removed except for a power line. CONSTITUTION: A SMPS(Switched-Mode Power Supply)(20) rectifies AC power inputted from the outside into direct current and supplies the direct current to apparatuses. A light sensor(40) receives data comprised of optical signals from the outside. A light-emitting diode module(10) emits light including optical data. A CPU(30) controls the illuminance and color of the light-emitting diode module based on data information inputted from the light sensor. A remote controller comprises various control switches and an optical transmitter.
