<p>PURPOSE: An energy saving electricity illumination system using a Doppler sensor is provided to effectively manage the illumination of a underground parking lot by using a simple device applying the Doppler sensor. CONSTITUTION: In a energy saving electricity illumination system using a Doppler sensor, a sensor(110) uses a Doppler sensor. A sensor distinguish the movement of vehicles and detects the moving speed of the vehicle. The control module(120) applies a high level and low level voltage to an LED lamp. A lamp unit performs high-level and low level illumination. An LED driver(130) controls dimming control and a constant current. The LED driver is flicked according to the control of a control module.</p> |
