Most models are still using ordinary halogen headlights, a little better models will use xenon headlamps. Most are done in the construction of some innovative lamps to improve the efficiency of light with a lens, and light reflection theory, but the lack of technological innovation lamp group itself. LED high brightness and strong penetration, the light intensity attenuation is much lower than halogen lamps. LED headlamps are so many advantages, and are practical, why does it come so late?

LED is short for Light Emitting Diode and it has a very popular Chinese name - a light emitting diode. They now often Roll boxes, signs, and all kinds of electrical lights and backlight appears. Can’t be issued before the LED Headlight is needed, "white", because in the visible spectrum which did not "white", it is not monochromatic, but a variety of monochromatic light synthetic compounds. The human eye can see white light, blue light mix needs two wavelengths of light yellow light or green light + light mix (this is TV's three primary colors) + blue + red light three wavelengths of light. Since these two methods require blue light, so the development of a blue LED white LED becomes an important technology nodes.

In 2008, Audi A4 on the first use of LED width lamp, opened the first LED headlamps era. After many manufacturers have begun to follow up, we are beginning to use LED width lamp. European legislation now even started, and to drive safely, all models in the sale are to be assembled LED width lamps. However, all manufacturers to only stay in the LED indicator lights and wide this step, and no further innovation. led explosion proof lighting https://www.eneltec-led.com/products/led-explosion-proof-lights

Until 2010, the second generation of the Audi A8 and the Mercedes-Benz CLS introduction, the true meaning of the LED headlamps emerge into people's sight. Recently, the new Passat is equipped with dual listing lens headlamps and LED headlights servo steering function, indicating the beginning of automotive LED headlamps popularity. best led headlights http://bestledheadlight.com/
