    A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. 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. And its principal - A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated.
