A LED Chip is an opto - electronical component that is made of an active layer which is put amongst a N and P type semiconductor and is constituted of its electrical connections. When a current is created on LED through the correct way, the electrons stimulate the active layer and the light becomes generated at that active layer.Afterwards the light which is generated spreads out through the window layer or the reflector.
