LED can only turn power ups in one direction ,it was called forward bias. when the current flows, the electrons and holes in which complexed and issued a monochromatic light which called electroluminescence effect. And the wavelength of light, color are relevant to the types of semiconductor materials and the incorporation of elemental impurities. Therefore it has advantages of high efficiency,long life, easy to break, high switching speed, high reliability and other traditional light source advantages.
We can supply
