LED and Optics

A light-emitting diode (LED) is a
semiconductor device that emits incoherent narrow-spectrum
light when electrically biased in the forward direction of
the p-n junction. This effect is a form of
electroluminescence. With help of LEDs you can make
Led sign boards and
LED Clocks to make your
shops attractive.
Life of one led is 100000 hours. The color of the emitted
light depends on the condition of the semi conducting
material used, and can be infrared, visible, or
near-ultraviolet.
Optics, as a field, is often considered
different from the physics branch. It is often called
optical science or optical physics. Applied optical
sciences are called optical engineering.Below are given
