Development status of automotive lamps


Automotive lamps have evolved from the most primitive candle lamps to incandescent lamps, tungsten halogen lamps, HID lamps, and LED lamps that have appeared in recent years. After more than 100 years of development, related technologies have matured. Especially since the world's first HID xenon headlight invented by German Hella in 1992, it has been more than ten years now. The international R&D and production technology of HID xenon headlights for headlight companies is quite mature. Hella, Koito, Visteon, Valeo and other headlight companies have been able to mass-produce them. One of the research and development priorities is AFS (Intelligent Variable light distribution headlight control system) headlights, HID (high intensity xenon discharge) headlights. GM Cadillac, BMW, Mercedes-Benz, Ford RSMondeo, Toyota Lexus, Hyundai AZERA and other international models have chosen to configure HID xenon headlights.


At present, another hot spot of international automotive lighting companies in the research of LED lights is white LED headlights and the combination of LED headlights and AFS. Among them, high-efficiency, high-power, high-reliability LED component research, lights and special The heat dissipation technology and optical design are the key. Due to the influence of the luminous efficiency of white LEDs, the current luminous intensity of LED headlights cannot be compared with HID headlights, but with the development of high-brightness white light LED research and development technology, the luminous intensity of headlights will be Further improved.
