Abstract:As its high luminous efficiency , energy-saving , environmental protection and other characters , Light-emitting diode ( LED) has been more and more dominant in the modern lighting .The more chip heat will be generated as the higher power , so the thermal problem has been one of the major factors .The sub-sectioned plain plate fin structure has been putted forward and analyzed by the numerical method .The result shows that the heat transfer coefficient and the thermal resistance rarely depend on the power input in the natural convection condition .The sub-sectioned plain plate fin can improve the heat transfer coefficient , but there has an optimum number for slotting .
