 LED light-emitting diode

LED Downlights LED (Light Emitting Diode), light emitting diode, is a solid state semiconductor devices, it can be directly to the electrically converted to light. The heart of LED is attached to a bracket on one end of a semiconductor chip, the chip, is the negative side, and the other end connected to the positive power supply, so that the LED Strip Lights whole wafer is epoxy encapsulated. The semiconductor wafer is composed of two parts, a part is a P type semiconductor, the hole in it dominant, the other end is an N-type semiconductor, in the side of the main electronic. But the two semiconductor linking between them to form a "PN junction. When the current through the wire act on the chip, the electron will be pushed to the P region, the P zone electron hole recombination, then will be issued in the form of photons of energy, this is the LED light-emitting principle. And the wavelength of light that is the color of the light is determined by the material to form a PN junction. GU10 LED Lamp
