Details Introduction
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, ele
