Mechanism Introduction for LED source

First, the light-emitting mechanism of LED lights source with incandescent or gas discharge lamp light-emitting principle is very different. LED spontaneous luminescence is due to the compound of electrons and holes. LED is formed by the P-type semiconductor layer P and N-type semiconductor the formation of the N layer, and into the middle of the double hetero structure active layers. The active layer is a light-emitting area, the use of external power injected electrons to the PN junctio...Continue reading
