LED industry in the world, is rapidly emerging as an important policy means of each countries for climate change, saving energy and international environmental regulations. And incandescent bulb regulatory policy in each country is the role of growth catalysts for the LED lamp industry, it is expected to increase research and investment for the LED package in the future. However, In spite of the growth of the LED lamp industry, the price of the world LED lamp has been declining more than 30% per year and it is accelerating further. Therefore, an alternative techniques for high performance and cost reduction of the LED lamp has been studied. In this study, we studied the aluminum extrusion product inserted heat sink as a one of the alternative techniques which can improve the thermal efficiency and reducing costs. As a result, radiant heat effect was improved around 44.5% higher than the thermally conductive resin heat sink.
