Led work lights for automotive

Wheel Loader Work Lights, Work Lights For loader
At first, LED was used as the indicator light source of instruments. Later, LED of various light colors was widely used in traffic signal lights and large-area display screens, which produced good economic and social benefits. The 12-inch red traffic light, for example, is a long-lived, low-light-performance 140-watt incandescent lamp that produces 2,000 lumens of white light in the United States. After passing through a red filter, the light is lost by 90%, leaving only 200 lumens of red light. In the new design, 18 red LED lights, including circuit losses, consume 14 watts of power to produce the same effect. Automobile signal lamp is also an important field of LED light source application.

To general illume character, people needs white illuminant more. In 1998, LED emitting white light was successfully developed. This LED is made of GaN chip and yttrium aluminum garnet (YAG) package together. The GaN chip emits blue light (λp=465nm, Wd=30nm), and the YAG phosphor containing Ce3+ produced by high temperature sintering emits yellow light after excited by this blue light, with a peak value of 550nLED lamp M. The blue LED substrate is installed in a bowl-shaped reflecting chamber and covered with a thin layer of resin mixed with YAG, approximately 200-500nm. Part of the blue light emitted by the LED substrate is absorbed by the phosphor, and part of the blue light is mixed with the yellow light emitted by the phosphor to produce white light.
For InGaN/YAG white LED, by changing the chemical composition of YAG phosphor and adjusting the thickness of phosphor layer, the color temperature of 3500-10000K white light can be obtained. This method of obtaining white light through blue LED has simple structure, low cost and high technology maturity, so it is most used.
