LED lamp applications Dec 21, 2016

Initially LED as a light source for instrumentation, then various color of LED traffic lights and has been widely used in large-area displays, producing good economic and social benefits. With 12 inches of red traffic lights, for example, in the United States is the use of long-life, low luminous efficiency of a 140-watt incandescent lamp as the light source.


It produces 2000 lumens of white light. After the red filter light loss 90%, only 200 lumens of lights. In the light of new designs, Lumileds Corporation 18 red LED light sources are used, including circuit losses, total power consumption 14 w, you can produce the same luminous efficiency.

Car lights are also important areas of application of LED light source. In 1987, China began to install high brake light in the car, due to the fast LED response (nanosecond), you can let the vehicles of drivers know the driving situation at an early date, reduce the incidence of rear-end accidents.


In addition, the LED lights red, green, and blue in the outdoor full color led display, key chain Mini Flashlight has been applied in many fields.
