Heat Dissipation Design of High Power LED Headlamp

Article Preview

Abstract:

High brightness white light emitting diodes(LEDs) are very promising in many new illumination applications. This paper is to investigate the cooling solutions of a LED heallamp. Air cooling with heat sink were proved to be unsuitable. A cooling method based on heat pipe is adopted which is proved to be effective. Simulations were performed with Flotherm software to investigate the thermal permance.A sample of LED headlamp is fabricated based on the structure of a certain sedan combined headlamp. The testing results are in accordance with the simulation results
