Abstract: LED lights have revolutionized the world by their performance. They consume less power as compared to previous lighting generations. However, large amount of power is dissipated in the form of heat. Therefore thermal management of LED is necessary to increase its life span and make it environmental friendly. For thermal management, aluminium heat sinks are widely used because aluminium profiles are easily manufactured and are good conductors of heat. In this article, we have intended to design the aluminium heat sink of eighty watt COB (Chip on Board) LED canopy light used in petrol pumps all around the world. We have designed the heat sink for 80W COB LEDs (40W each), and analysed the junction temperature through ANSYS fluent simulation. This design of heat sink and its fins are optimum and Thermal Interface Material is also used.
