    Text: 02.2008 Power Management for LEDs High Performance Analog ICs LEDs and LED Driver Technology A light-emitting diode LED is a semiconductor device that emits incoherent narrow-spectrum light when electrically forward biased, resulting in a form of electroluminescence. The color of the emitted light depends on the chemical composition of the semiconductor material used, and can be near-ultraviolet, visible or infrared. LEDs are more prevalent today
