LED (light emitting diode), the LED is a solid state semiconductor devices, and the light that it can be converted directly into electricity. LED is a semiconductor chip, mounted on a bracket on side of the heart, one end is negative, the other end connected to the positive power supply so that the entire chip is epoxy. Semiconductor chip is composed of two parts, the part of the p-type semiconductor, dominate in the hole, and the other end is an n-type semiconductor, here is primarily electronic. But the connection between semiconductor to form a "PN junction". When the current through the wires on a chip, electrons will be introduced to the p, p-Exciton complex, then with photon energy, and this is the principle of LED luminous form.Wavelengths of light colour is determined by materials on the formation of PN junction.
