Research on Optical Design of High-Power White LED Automobile Headlamp

Along with the advance of automotive lighting technology, white LED has been widely applied in automobile headlamps system, by its advantages of long life, small volume, high luminous efficiency, energy saving, environmental protection, and replace the other light. Due
to the luminescence characteristics of the LED light source which is solid cold light source are different from traditional automotive headlamp light, we need redesign the secondary optical system design in order to satisfy the requirement of the national standard. Therefore, research automobile headlamp system based on high-power white LED sources has very important significance.
