Abstract :
The excellence of energy efficiency and reliability of LED attract the application of outdoor area lighting. The trends toward increase of power density while minimizing the structure, made the heat dissipation design challenging. The thermal performance of a novel streetlight module with embedded heat pipe is investigated in this study. The thermal performance of the new module is compared with a common module with only metal fins design. The thermal capabilities, including temperature uniformity and thermal resistance of heat pipe under different heat loads have been investigated experimentally and analyzed using finite element modeling. The comparison of the thermal properties is presented, and the implication on design capability and reliability is discussed.
