We design a substrate-heat pipe cooling system for a high-power 80 W LED in a large space with natural convection. Effects of LED input power and heat sink tilt angle on LED junction temperature and luminance are studied. The experimental results show that this heat pipe cooling system can reduce the LED junction temperature to 73.5 ℃. The results also indicate that LED input power and heat sink tilt angle have strong effects on LED junction temperature and luminance.
Key words： high-power LED; junction temperature; tilt angle
