Led lighting system project


A light emitting diode (LED) is a device which converts electrical energy in to
light. LEDs are preferred light sources for short distance (local area) optical
fiber network because they are inexpensive, robust and have long life (the long
life of an LED is primarily due to its being a cold device, i.e. its operating
temperature being much lower than that of, say, an incandescent lamp), can be
modulated (i.e. switched on and off) at high speeds.
