Light emitting diode is fabricated by forward biased of p-n junction which converts the electric energy into optical energy as infrared and visible light region. WORKING OF LED Being in forward biased of led thin depletion layer and low potential barrier provides the maximum no.of diffusion of charge carrier as electron and holes . When high energy of electrons in conduction band are combined with low energy of holes in valance band.this energy difference realeased in the form of photon.which may be seen as light energy.
