now led lights has entered innumberable families, what is the led? What is the characteristic? One answer for you today.

leds is an electroluminescent semiconductor chip, with silver or white adhesive curing on the scaffold, and then use silver or gold wire connection chip and circuit board, sealed with epoxy resin around, maintain the effect of internal core, the last device shell, so the LED of the seismic performance is good.

the first LED is used as the indicator light instrument and then all kinds of light color of LED traffic light and display screen has been widely used in large area, produced good economic and social benefits. 12 inches of red traffic light, for example, in the United States was chosen long life, low luminous efficiency of the 140 - watt incandescent lamp as light source, it produces 2000 lumens of white light. After red filter, light lost 90%, only 200 lumens of red light. And in the light of the new design, surveying of land chose 18 red LED light source, including circuit loss, total power consumption of 14 watts, can produce the same light. An important category of car lights and LED light source used.
