LED lamp is the future light darling still need time to popularize

Shortly before the Geneva Motor Show, the third generation Audi TTCoupe introduced the LED lighting formally with the media meet, exquisite LED lights replaced the original xenon lamp assembly, has become a major highlight of the show.
One year spent similar, each year is different. Automobile industry technology is changing with each passing day, and new technology is replacing the old technology. The direction of the development of the automobile industry is gradually moving towards intelligent and green environmental protection. The development of automobile light source technology is also the case. In recent years, the auto show, we can see a number of models equipped with a variety of colorful LED lights, attracting the eyes of the vast number of consumers.
LED (Emitting Diode Light), translated as light emitting diode, is a light-emitting semiconductor electronic components. And LED lights, as the name suggests, is the use of LED as the light source of the car. Because of its high brightness, rich color, low power consumption, long life and other characteristics, in recent years, LED has been widely used in the automotive field.
The history of the development of the car lights
The origin of the development of the car lights can be traced back to the end of nineteenth Century. In 1898, the Columbia electric vehicle for the electric headlights and taillights, this electric lamp was born. After more than a century of evolution and development, the car lights have become an integral part of the vehicle to ensure safe driving.
Throughout the course of development of light, it is not difficult to see that this is a miniature of the history of the development of science and technology. The first generation of automotive lamps are incandescent lamps. In 1913, the advent of incandescent lighting, the working principle is current through the wire, hot tungsten filament produced light radiation, the light emitted by the bright light. Incandescent lamp has brought about the revolution of automobile lighting. In 1925, electric lighting has been widely used in automobiles.
Turn the page, we came to the age of the second generation of lights - halogen lights. Halogen lamp is a new generation of incandescent lamp. If to improve the luminous efficiency of incandescent lamps to improve the tungsten filament temperature, but the corresponding will cause tungsten sublimation and sublimation in the glass shell to black. In the incandescent lamp filled with halogen or halide, using the principle of tungsten halogen cycle can eliminate incandescent bulb blackening. This is the halogen light source, was born in 1960. Compared with the traditional incandescent lamp brightness, long service life, more energy saving. Now many car headlights still use halogen lamps.
Came to 1991, the age of xenon headlights finally arrived. Xenon lamp, the English abbreviation is HID (Intensity Dis-charge Lamp High), namely the high intensity gas discharge lamp. Xenon lamp is one of the high efficiency light source which is made by using high voltage and high pressure inert gas. The light intensity of the light is 2 times of the ordinary halogen lamp, and the energy consumption is only 2/3, and the service life can reach 10 times of the ordinary halogen lamp. Xenon lamp greatly increases the safety and comfort of driving, and helps to relieve the tension and fatigue of people at night.
After several generations of evolution, and finally to now lead the development trend of the LED light source technology. LED is the abbreviation of Emitting Diode Light (light emitting diode), which was born in 1960s. LED has many advantages. Because it is not a hot light source, the service life of up to 5~10 years, in addition, there are rich colors, safety, environmental protection, shock resistance and shock resistance, but also has the advantages of small size and environmental adaptability. These characteristics are very attractive to the automotive lighting system. It can be said, LED light source is a very ideal light source, due to the high cost, technical and regulatory relationship, LED as a car headlight is still not mature.
After a century of development, car lights from the beginning solely for the purpose of lighting, until now used in night vision, decoration and other purposes, I believe that in the near future, there will be more and more with the advantages of technology to lead the development of automotive lighting.
