Leds are English light emitting diode (LED), its basic structure is an electroluminescent semiconductor chip, silver white glue or adhesive curing to the bracket, and then use silver or gold wire connection chip and circuit board, and then sealed with epoxy resin around, protect the internal core, final installation of the shell, so the LED of the seismic performance is good. Using field involving mobile phone, desk lamp, household appliances and other daily household appliances and machinery production.



LED (Light Emitting Diode), light-emitting Diode, is a kind of ability to electric energy into visible Light solid state semiconductor devices, it can be directly put DianZhuan into Light. 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 of the anode, the 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 light. And the wavelength of light was the color of the light, is determined by the formation of p-n junction material.




(1) a new type of green environmental protection light source: LED cold light source use, small glare, no radiation, does not produce harmful substances in use.


(2) long life: LED solid cold light source, epoxy resin encapsulation, shock resistant, no loose parts in the body, there is no filament light easy to burn and thermal deposition, droop, such as faults, service life can reach 60000 ~ 100000 hours, is a more than 10 times the service life of the traditional light source. LED performance is stable, can be in - 30 ~ 50 ° C + normal work environment.


(3) transform, the LED light source available red, green, blue three colors principle, in under the control of computer technology make the three colors gray level 256 and arbitrary mixed, can produce 256 x256x256 (16777216) colors, forming different color combinations. Combination of LED light color changing, can realize the dynamic change of rich and colorful effects and all kinds of images.


(4)  high and new technology compared with traditional glow of light, LED light source is low pressure microelectronics products, successfully combines computer technology, network communication technology, image processing technology and the embedded control technology, etc.
