SMD LED, its luminous principles is the current through the compound semiconductor, through a combination of electrons and holes, excess energy will be releasedas light, to glowing effect.
SMD led characteristics
① Cold glow serves the principle is of light, rather than through heating and discharge luminescence, so about 50~100 times longer life than the tungsten lamp, about 100,000 hours.
② No warming lamps and light response speed faster than General Electric (~ 3 ~400ns).
③ Electro-optical conversion efficiency, low power consumption, energy consumption than the bulb about 1/3 ~ 1/20.
④ Excellent shock resistance, high reliability and low running costs of the system.
⑤ Is small, thin, lightweight, no shape limits, easy to make all kinds of applications.
