Highlighting light-emitting diodes (leds) small kind, thought change ma3 jia3 don't know you!

a lot of people to highlight light-emitting diodes (leds) this name is not quite understand, in fact it is the LED we used to say, is to use an aluminum gallium arsenide and gallium arsenic, and gallium nitride materials, such as its internal structure is a p-n junction, with unidirectional conductivity, diode rectifier, detection, is the main purpose of voltage stability, clamping clipped and transfiguration.

when the leds on the PN junction and the forward voltage, p-n junction barrier can be reduced, the spread of the carrier is greater than the drift motion, making the hole injection of p area to N, N the electronic injection to p, such mutual injection hole after an encounter with the electronic produce compound, compound produced when much of the energy in the form of light, and light. And light-emitting diodes (leds), which used the material is different, you can make different colors of light, common red light, yellow light, green light, infrared light, etc.
