Like ordinary diodes, light-emitting diodes are composed of a PN junction, and they also have unidirectional conductivity. When a 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 contact with the electrons in the N area and the voids in the P area within a few microns of the PN junction. The holes recombine and produce spontaneous emission fluorescence. The energy states of electrons and holes in different semiconductor materials are different. When electrons and holes recombine, the energy released is somewhat different. The more energy released, the shorter the wavelength of the emitted light. Commonly used are diodes that emit red, green or yellow light
SMD LED red lamp beads LED lamp beads Light-emitting diodes are commonly used light-emitting devices that emit energy through the recombination of electrons and holes to emit light. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy, and have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices.
