AB - [This research an innovative window type Venturi cooling system to help reduce the high power LED emitting heat on working. It uses lamp-shape heat sink base that is coated by aluminum nitride (AlN) ceramics to be an insulation layer which can reduce the damage of emanating heat and promote the working hours of high power LED. It is obviously seen that the force convection contributes a lot on heat dissipation when vehicles running. The record shows that the highest temperature comes to 96.4 °C, 93.3 °C and 89.8 °C on the high power LED headlamps of 85 W, 80 W and 100 W separately without the convection window design. The other record shows that the temperature comes to 74.6 °C, 73.7 °C and 64.8 °C on the same lamps but with cooling down window embedded. The effective cooling down temperature is 21.6 °C, 19.8 °C and 25 °C. The heat dissipation performance contributes 22.61%, 21% and 27.83%. By the analysis of finite elements on window type Venturi system shows that experiments data coincides with theory assumption. This project absolutely shows that an innovative window type Venturi cooling system is highly effective on heat dissipation and can provide more competitive high power LED products in the market.
