Future LED Headlamps——Opportunities to improve Light Performance

摘要

1 IntroductionFirst LED headlamps have been launched for production in automotive vehicles.The major driving factor to introduce LED light sources at this time for the main headlamp functions is the styling and design flexibility.Additionally,the special white-bluish light colour is well appreciated by the human eye.Nevertheless,the light performance given by the 70mm Bi-Xenon projector unit of today is still the benchmark for driving at night.As the LED's will develop in terms of low power consumption,long life time,luminance and luminous output there will be opportunities in the future to contribute with LED's also in terms of improved light performance,the main target for a safe driving at night.
