LED lighting has been developed rapidly in the near future. LED is widely recognized as a clean source of green and environmental protection. LED light source has long service life, energy saving energy saving, simple and convenient application and low use, so it is in LED flashlight, LED lamp and portable lighting facility. The structure and working principle of LED lighting are as follows.

LED is mainly LED light emitting diode, which is a solid-state semiconductor device that can be converted directly into light. The heart of the LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, the other end is connected to the positive electrode of the power supply, and the whole wafer is encapsulated by epoxy resin. Semiconductor chip consists of three parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, mainly electronics, here in the middle is usually one to five cycles of quantum well. When a current flows through a wire to the chip, electrons and holes will be into the quantum well, quantum well in electron and hole recombination, then will be issued in the form of photon energy, this is the principle of LED.

LED light source, major technical breakthrough was when ultrafine grain LED encapsulation special permutation and combination of technology, at the same time, using LED p-n junction diode rectifier, characteristics and semiconductor processes in which plays a very important role. The AC LED is integrated into a bunch of tiny grain through the semiconductor process, using staggered matrix arrangement process, and adding bridge circuit to chip design, so that AC current can double guide and realize luminescence.
