Automobile automotive lighting devices are important safety components. In order to improve driving safety and comfort, many new car lights are being developed. This paper introduces the HID headlamps, infrared headlights, LED automotive lights and lighting systems, intelligent vehicles and car shows in the light of these new technologies in advanced electronics applications. Finally the lights Co., Ltd Shanghai Koito technological advances in this area.

Now, the general use car headlights are halogen light source. HID Headlamp is a high-intensity discharge (High Intensity Discharge-HID) light source. Specifically, the application of automotive headlamp low-power 35-watt metal halide lamps. Used in the automotive headlamp brighter than halogen light, longer life of HID lamps, are the following reasons:

1, saving the need - with the development of automotive electronics, automotive electrical components in the increase, it is necessary to reduce the power consumption of individual devices, and headlamp is particularly power-hungry devices.

2, for safety and economy, want to have a longer life - with the formation of high-speed road network, increased the chances of traveling long distances at night, headlight increased frequency of use, and thus the life of the light requirements also will be to improve. Obviously, the longer the life of light source, the higher the safety of the vehicle. In addition, if the source of life long enough to be compared with the vehicle's life, that life of the car without changing the light source, eliminating the need for maintenance costs in this regard, it is more economical.

3, the driver increased the speed of aging and the hope that a higher intensity lights - With the improvement of health, aging drivers with the trend. Recently China has been the driver to extend the age from 60 years to 70 years. Compared with the young, the elderly a lot of vision loss. To compensate for the elderly and slow vision loss and other defects, the need to improve the level of lamp illumination. In addition, the speed on the highway improvement also requires lights provide better lighting to improve road safety.

4, streamlined body to adapt to the needs - in order to improve vehicle aerodynamics, streamlined body design as. This triggered a headlamp and headlamp lenses reduce the size of the surface slope increases. To compensate for these causes reduced the amount of light, it is necessary the use of brighter light.
