High Efficient LED Headlamp Design-Styling versus Light Performance

With an urgent need for energy conservation and pollution reduction, the trend of replacing traditional incandescent or fluorescent lamps with high-power LEDs is growing more and more popular. However, heat dissipation of high-power LED is the main bottleneck for its application. In this research, a kind of automotive headlamp low beam system model is designed with high power LED chips. Several different cooling devices are designed for headlamp cooling, the heat dissipation performances are simulated and analyzed both by the finite volume method (FVM) in FloEFD and experimental measurements. The obtained results indicate that loop heat pipe combined with fined heat sink is the most effective way for heat dissipation in the designed automotive low beam system, even in 80¡æ environmental temperature can ensure the LED headlamp system working stability. The research lays a theoretical basis for the follow-up study.
