informaciones en detalle
LED is the heart of a semiconductor chip, the chip attached to one end of a stent, is the negative side, the other end of the positive power supply, so that the whole chip is epoxy encapsulated. Semiconductor chip consists of two parts, part of P-type semiconductor, the hole in it dominates the other side is N-type semiconductor, here is mainly electronic. But when the two semiconductor connected between them to form a PN junction. When the current through the wire, when applied to the chip, electronics will be pushed to P zone, with the P zone electron hole recombination, and then will be issued in the form of photon energy, which is the principle of LED light. The wavelength is the color of light is the formation of PN junction of the material by the decision. Widely found in everyday life, such as household appliances lamp, car tail fog and so on. LED's most notable feature is the long life, high photoelectric conversion efficiency.
