Led stands for light emitting diode which is a semiconductor light emitting diode. Led light Panel consists of a semiconductor and it dipped in impurities in such a way that it forms a p-n junction so that the flow of electrons can be made inside the semiconductor. Led lights operates at low temperature and consumes very less amount of electricity so it is the best alternative of traditional sources of light. In previous days when led lights discovered thane these lights are mainly used in laboratories and electronic equipments but due to the light efficiency now incandescent lamps are totally replaced by these led lights in every place.
Now led lights are available in several colors, but white, blue and red led comes first of all and after that by mixing of colors several colors can we find. A single led light produces a very small amount of light so many places where we need much light, then we use led light panel which are a serial combination of single lights.Leds panels are mainly two types I-conventional and surface mounted device. Many street lights.
