The cooling and optical failure Of LED automobile headlamps

The high-power LED is applied as the light source of automobile headlamp. Only by solving the issue of LED high efficiency cooling can the goal of using LED as vehicle energy-saving lighting be achieved. Therefore, how to reduce the impact of the LED headlamps working temperature on optical failure and life has become a serious technological problem, and it must be correctly solved. This paper focuses on addressing the ideas and methods of high-power LED in automobile headlights on the LED cooling and optical failure, using test samples and targeted products to obtain the relevant data, doing some beneficial exploration of the automotive technology for energy-saving, environmental protection and new industrical energy development.
