LED is a kind of electron diode, the main structure is PN junction. When the voltage is applied to both ends of the LED, the electrons absorb the energy and transfer it to the valence electron belt, then release the absorbed energy. The energy released is light. The wavelength and color of the light emitted are determined by the electrical potential of the semiconductor
