LED Headlamp를 적용한 LHPS 냉각성능 해석

The influence of the heat sources on LED junction temperature are Engine room air, Back plate, Electric power device, and so on. LED headlamp cooling system is considered to be an important subject for high light efficiency. Because LED Chip will be problem When LED junction temperature be over 135℃. In this Study, the Looped Heat Pipe System is considered to prevent LED Chip fall. The LHPS is consist of evaporator part, condenser part, heat pipe part. The working fluid of LHPS is HCFC-123.
