VEHICLE DETECTION CONTROL SYSTEM AND METHOD FOR HYBRID STREET LAMPS

摘要

PURPOSE: A vehicle-sensitive hybrid street light control system and method thereof are provided to control illuminance and dimming using a high pressure discharging lamp and an LED lamp. CONSTITUTION: A first light unit is made of LED lamps. A second light unit is made of a discharging lamp or an HID discharging lamp. A sensor for sensing surrounding brightness is attached to a hybrid street light(400~N). Sensor 1(100) transmits a vehicle sensing signal to a central control device(300). Sensor 2(200) is separated from sensor 1 in a forward direction. The central control device calculates vehicle speed using time received from sensor 1 and sensor 2.
