In 2010, the Chinese LED industry has great development and progress. Whether it is government policy to support the LED industry, or LED technology advances, he gave us has left a deep impression. To save energy , reduce greenhouse gas emissions, the world regard the LED lighting industry as the new generation of green growth industries, with emphasis to be cultured, the development of LED lights are in full swing in the automotive sector.

Widely used in automotive lighting. Until 1990, HP, Toshiba Corporation of Japan launched the intensity more than to 1000mcd the of InGaAlP / GaAs structure of red, yellow high-brightness LED, Nichia Corporation of Japan in 1993 invented InGaN/Al2O3 Lan, green high-brightness LED signs, technically paved the way for the automotive light source LED technology and mass production.

1985 LED car lights first appeared in the passenger cars, the 1986 Nissan300zx cars use LED brake lights began officially marked the era of LED automotive lighting. International famous brands such as BMW, Cadillac, Buick, Volkswagen, Ford, Mercedes, Toyota, Mitsubishi, Mazda and Skoda, etc. has introduced LED automotive lighting.

LED auto lamp annual rate of double-digit growth in output value has reached $ 546 million in 2005, accounting for 14% of the LED application in the world. China the first to use LED brake lights in 2000 in the Shanghai Volkswagen Santana 2000. China s LED automotive lighting annual rate of 70% -80% in the growth of LED automotive lighting an annual rate of 70% -80% growth in 2006 the output value of more than 100 million yuan.

2010 China s LED automotive lighting is referred to as "LED first year, the domestic LED industry was the explosive growth of increasingly wide range of applications in the automotive sector is being constantly pay attention to it.

Future LED with the LED to improve the quality, prices fell to a wider range of applications in the car.

Shall be designed to take into account two aspects

Directly with optical headlights parts, the main light source, mirror with light microscopy of three parts, collectively referred to as the lighting crew. The lights of the optical design is the headlight design of the lighting group. The primary consideration of the design of the led strip team principles: First, in line with the OEMs the overall structure of the lights, the modeling assumptions; second is to meet the national norms and standards.

LED light source should be based on the requirements of the different lamps luminous flux, the choice of power LED LED array. The mirror is designed to improve the light source light and to achieve the performance requirements specifically designed to mirror with light, its role in the light emitted radiation to the mirror on the luminous flux by a certain distribution of irradiation. With light microscopy is a mirror reflecting the light distribution pattern with light microscopy will be light offset or scattered to the desired location, in order to achieve the requirements of the distribution o f light.

A long time, car lights, incandescent point source as reference to determine the lighting design of the lamp, and the formation of the corresponding software. Lighting norms and standards is also in order to develop. LED light source has its own characteristics, the design and manufacture of led underground light automotive lights can not simply apply the conventional method, for their design and manufacturing methods to make changes, to develop norms and standards compatible with the LED car lights.
