Each component in the LED package has a significant role in heat dissipation. In this paper, a simulation study was done to scrutinize the influence of heat slug shape on the heat dissipation of single chip LED package using Ansys version 11. Two types of heat slug shapes, rectangular and cylindrical were used. The analysis was carried out under natural convection condition at ambient temperature of 25°C. Simulated results indicate that rectangular shape heat slug exhibits better heat dissipation. 2015-03-04T08:52:01Z 2015-03-04T08:52:01Z 2014-02 Article Advanced Materials Research, vol. 893, 2014, pages 807-810 1662-8985 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/39066 http://www.scientific.net/AMR.893.807 en Trans Tech Publications Inc.
