What are the characteristics of SMD LED

Time: 2021-08-13 View: 952

Why does the SMD LED emit light? When the current passes through the compound semiconductor, through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of light emission. SMD LED solves the problems of brightness, viewing angle, flatness, reliability, and consistency. SMD LED has many characteristics:

①The principle of luminescence is cold luminescence, not by heating or discharge, so the life of the component is about 50-100 times longer than that of a tungsten bulb, which is about 100,000 hours.

②No warm-up time is needed, and the lighting response speed is faster than ordinary lamps (about 3 ~ 400ns).

③ High electro-optical conversion efficiency, low power consumption, saving about 1/3 ~ 1/20 of energy consumption than light bulbs.

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

⑤ Good shock resistance, high reliability, and low system operating cost.

⑥Easy to be small, thin, lightweight, without shape restrictions, and easy to be made into various applications.
