Light emitting diode or LED is similar to the working of the normal PN junction diode where the generation and recombination of the charge carriers takes place. But during the recombination process while the charge carriers move from conduction band to the valence band, there is a light emitted in the visible light region which comes in various colors depending on the type of the semiconductor material used. This is the working principle of the LED.
The normal semiconductor material is not used for the construction of the LED. The GALLIUM ARSENIDE is used for the construction of the LED.
