This paper deals with thermal flow analysis of LED lighting that is widely used in athletic facilities, underpass, household luminaries, etc. Recently, LED lighting is in the process of replacing the existing light sources based on the advantages of eco-friendliness, energy efficiency, high lifespan, etc. However, the heat generated from LED may lower the reliability of LED lighting by raising the temperature of chips. In this paper, it is verified that changing the form of the existing flat heatsink to a mechanically twisted structure without using a heat pipe for a 600-watt LED lighting is more effective for convectivity. Thermal analysis has been performed using a software, Solidworks-Flow Simulation 2017 version. The temperature analysis also has been performed according to the change of thickness of a heat sink at the room temperature. Through the analysis, average temperatures of the heatsink with 1.5 thickness are lower than that of the heatsink with 1.0 or 1.2 thickness.
