How LED's work - A light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn-junction diode, which emits light when activated.[4] When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

How LED's Work? An LED is a special type of diode that is specifically optimized to give off light, usually in the visual or infrared spectrum, as electricity is passed through it.
