When the forward voltage is applied to the light-emitting diode, the holes injected from the P area to the N area and the electrons injected from the N area to the P area are respectively in the vicinity of the PN junction with the electrons in the N area and the P area. The holes recombine to produ......

A light-emitting diode (LED) is a light-emitting display device made of semiconductor materials such as gallium phosphide (GaP) that can directly convert electrical energy into light energy. When there is a certain current passing through it, it will emit light.
