AIRFIELD LIGHT SYSTEM USING A LUMINESCENT DIODE LAMP

摘要

PURPOSE: An airfield lighting system is provided to prevent an LED lamp from being damaged by constantly maintaining the brightness of an LED lamp when a load is changed. CONSTITUTION: A terminal filter(20) filters a high frequency signal inputted to a constant current controller(10). A plurality of discrete bulb control devices(40) is electrically connected to a plurality of isolating transformer for power supply. A plurality of LED drives(50) is electrically connected to a plurality of individual bulb control devices. A plurality of LED lamps(60) is electrically connected to the plurality of LED drives. A serial communication device is electrically connected to the communication isolating transformer. A main control device drives the plurality of individual bulb control devices to turn on or off the LED lamp.
