Light Emitting Diode

Introduction Alight-emitting diode(LED) is asemiconductorlight source. LEDs are used as indicator lamps in many devices and are increasingly used for otherlighting. Introduced as a practical electronic component in 1962,early LEDs emitted low-intensity red light, but modern versions are available across thevisible,ultravioletandinfraredwavelengths, with very high brightness. When a light-emittingdiodeis forwardbiased(switched on),electronsare able torecombinewithelectron holeswithin the device, […]
