LO Posted February 17, 2003 Report Posted February 17, 2003 OK here goes....... LED (Light-Emitting Diode) - Consists of surface mount LED’s, which are situated in series along the bottom of a shallow plastic tray (array lit) or the edges of display (edge lit). Life time: long, typically 50,000 hours Simple connection +5 VDC (Anode) and ground (Cathode) EL ( Electro Luminescent) - A thin membrane consisting of two coated electrode plates with an aluminum reflector. When AC voltage is applied to the electrodes, the electrons collide with the light emission core. The energy given off is light. Inverter (DC to AC) is used to power electro luminescent lamps. Service Life: 1500-4000hours LO
