Details:
LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor devices, which can be converted directly into electricity to light. LED\'s heart is a semiconductor chip, the chip is attached to one end of a stent, the end is the anode and the other end to connect the positive power supply so that the whole chip is epoxy-encapsulated together. Semiconductor chip consists of two parts, part of P-type semiconductor, in its dominant position inside the hole on the other side is the N-type semiconductor, in the side of the main electronics. However, when the two kinds of semiconductors connected between them to form a PN junction. When the current through the wire, when acting on the chip, the electronic will be pushed P area in the P district electron with the hole recombination, and then will be issued in the form of photon energy, this is the LED light-emitting
