LED light-emitting mechanism works and what?

LEDs are made Ⅲ-Ⅳ compounds, such as GaAs (gallium arsenide), GaP (gallium phosphide), GaAsP (gallium arsenide phosphorus) and other semiconductor made of, its core is the PN junction. Therefore, it has a general PN junction iN the characteristic that the forward pass, reverse cut-off, breakdown characteristics. in addition, under certain conditions, it also has a light emitting characteristic. in the forward voltage, electrons injected from the n area P area, hole injection from the P region N area. Into other areas of minority carriers (minority) part of the majority carrier (more children) composite and light.
