LED automotive lamps gradually fiery was hailed as the industry big cake"

China 2010, LED industry has a great development and progress. Whether in the government's policy support for the LED industry, or the progress of LED technology, we have left a deep impression. In order to save energy and reduce the greenhouse effect, all countries in the world regard the LED lighting industry as a new generation of green growth industry, focusing on training, in the field of automotive LED lights are also in full swing.

Widely used in automotive lamps. Until 1990 the United States HP company, Toshiba Co of Japan launched InGaAlP/GaAs more than 1000mcd of the structure of light red, yellow high brightness LED and 1993 Nichia Corporation of Japan invented InGaN/Al2O3 blue and green high brightness LED as a symbol, from the technology and mass production and paved the way for the car light source LED.

1985 LED car signal light appeared on the bus for the first time, in 1986 the use of Nissan300zx LED high brake lights marked the beginning of the era of LED auto lamps. The world famous car brands such as BMW, Cadillac, Buick, Volkswagen, Ford, Mercedes Benz, TOYOTA, MITSUBISHI, Mazda and Skoda has launched LED auto lamps.

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

In 2010, China's LED auto lamps are known as "the first year of LED", the domestic LED industry is explosive growth, the application is also more and more widely, in the automotive sector has also been attached importance to.

Future LED will improve the quality of the LED, the price decline in the car to get a wider range of applications.

Design must take into account two aspects

Directly related to the optical components of the main lights, reflectors and light distribution mirror three parts, collectively referred to as the lighting group. The optical design of the lamp is the design of the lamp group. The design principle of the lighting group is the first consideration: first, it is consistent with the overall structure of the vehicle, the design idea; two is to meet the requirements of the national norms and standards.

LED light source should be based on the requirements of different lamps on the luminous flux, the use of different powers of LED array composed of LED. The reflector is designed to improve the light output rate and meet the requirements of light distribution performance of the special design of the mirror, the role of the light emitted from the light source to illuminate the mirror on a certain distribution. The function of the light distribution mirror is that the light reflected by the reflecting mirror is distributed or scattered to the required position through the pattern on the light distribution mirror to achieve the requirement of light distribution.

For a long time, the car light to incandescent light source as a reference to determine the lighting design, and the corresponding software. Lighting standards and standards are also used to develop. LED light source has its own characteristics, design and manufacture of LED automobile lamp cannot simply apply the conventional methods must be done to modify its design and manufacturing methods, and to develop and adapt to the norms and standards of LED automobile lamp.

Spent the first year of 2010LED, LED auto lamps have been more widely used, the industry is expected to 2015, China's LED industry will reach 500 billion. Right now, with financial investment in energy-saving emission reduction, LED automotive lamps to promote the industry to become optimistic about the big cake.
