LED automotive lighting industry has become a 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 lighting. 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 lights for the first time in 1986 on the bus, Nissan300zx type automobile use LED high brake lamp marks LED auto lamps era began. 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 every year with the speed of two digit growth in 2005, output value reached $546 million, accounting for 14% of world LED applications. 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.

2010 China LED auto lamps known as the "LED year", the domestic LED industry was the explosive growth, more and more wide range of applications in the automotive field, also continue to pay attention to it.

LED will be the future with LED quality, prices, get more extensive application in the car.

Design must take into account two aspects

Directly with the relevant parts of the main optical light source, a reflector and lens three, referred to as the group of lights. 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 according to the different requirements of lamps of luminous flux, with different power LED LED array. 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.

Long, car lamps with incandescent lamps light as a reference to determine the lighting design of lamps, and 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 2010 LED first year, LED auto lamps are widely used, the industry is expected to 2015, China LED industrial scale 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.
