 led outdoor area street lighting light principle
led outdoor area street lighting, is a semiconductor solid-state light-emitting devices. It is the use of solid semiconductor chips as a light-emitting material in the semiconductor through carrier recombination emission of excess energy caused by photons emitted directly to the red, yellow, blue, green, green, orange, purple, white light. LED lighting products is the use of LED as a light source manufactured lighting.
PN junction voltage constitutes a certain potential barrier, when plus forward bias voltage barrier down, P and N area majority carriers spread to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will be diffused into the P region to form the minority carriers in the P region. These electrons recombine with holes on the valence band, and the energy obtained from recombination is released as light energy. This is the principle of PN junction light.
