AIRFIELD LIGHT SYSTEM USING A LUMINESCENT DIODE LAMP

摘要

PURPOSE: An airfield light system is provided to constantly maintain the brightness of an LED lamp by controlling the brightness of the LED lamp through a constant current control. CONSTITUTION: A terminal filter(20) filters a high frequency signal inputted to a constant current controller(10). A plurality of bulb controllers(40) is electrically connected to a plurality of isolating transformers for power supply. A plurality of LED drives(50) is electrically connected to the plurality of bulb controllers. A plurality of LED lamps(60) is electrically connected to the plurality of LED drives. A main controller is electrically connected to a serial communication device. The main controller drives the plurality of bulb controllers for turning on or off the LED lamp.
