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
a,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.
b,No warming lamps and light response speed faster than General Electric (~ 3 ~400ns).
c,Electro-optical conversion efficiency, low power consumption, energy consumption than the bulb about 1/3 ~ 1/20.
d,Excellent shock resistance, high reliability and low running costs of the system.
e,Is small, thin, lightweight, no shape limits, easy to make all kinds of applications.
