The Summarize of High Power LED Headlamps Cooling Design of Automobile

Abstract:

With the luminous flux of highpower white LED has been further improved, LED will gradually replace incandescent lamp and halogen lamp, and become the fourth generation light source of automotive lighting. Now there are still a number of technical difficulties in LED application for automotive headlamp, one more difficult to overcome of which is the heat dissipation problem of LED headlamp. In this paper, the current LED headlamps heat dissipation solutions are introduced; and the future direction of improving the heat dissipation is given.
