LED means "light-emitting diode is a two-lead semiconductior light source. it is a basic PN-junction diode,which emits light when activated.when a suitable voltage is applied to the leads,electrons are able torecombine with electron holes within the device,releasing engergy in the form of photons.This effect is called electroluminescence,and the color of the lightis determined by the energy band gap of the s emiconductior.
