SMD LED is the meaning of surface-mount leds, SMD patch helps to improve the production efficiency, as well as the application of different facilities.Is a solid-state semiconductor devices, it can be directly put DianZhuan into light.Its voltage of 1.9-3.2 V, the red light, yellow light the lowest voltage, the heart of the LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power supply positive, make whole chip is encapsulated by epoxy resin.Semiconductor chip consists of two parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, here is mainly electronic.But this two kinds of semiconductor connected, forming a p-n junction between them.When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED.And the wavelength of light was the color of the light, is determined by the formation of p-n junction material.
