The basic structure of the LED is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver or gold wires, and then sealed with epoxy resin around to protect the interior. The role of the core wire, the last installation of the shell, so the shock resistance of the LED lamp is good. LED is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is recombined with hole, then will send energy with the form of photon, the principle of LED light that Here it is. And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.
