LED chip lamp bead is a simple lamp. Its luminous principle is to pass the current through the compound semiconductor, through the combination of electrons and holes, excess energy will be released in the form of light to achieve the luminous effect. It is mainly used in lighting system, decoration, electronic equipment indicator, backlight, display, apparatus and other fields.

① The light emission principle is cold light emission, rather than light emission by heating or discharging, so the service life of the element is about 50~100 times longer than that of the tungsten filament bulb, about 100000 hours.

② There is no need to warm up the lamp, and the lighting response speed is faster than that of ordinary electric lamps (about 3~400ns).

③ The electro-optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3~1/20 less than that of bulbs.

④ Good shock resistance, high reliability and low system operation cost.

⑤ Easy to be small, thin, lightweight, no shape restrictions, easy to make all kinds of applications.
