LEDs provide efficient lighting solutions. Their main advantages are efficiency, reliability and durability. Although LEDs operate cooler than conventional incandescent bulbs, it is necessary to achieve maximum heat transfer in order to maintain or improve their efficiency and lifespan. Heat sinks in LED modules provide a path for heat to flow from the source to the outside ambience. Heat sinks with different fin geometries are analyzed to determine its influence on thermal performance and airflow around the fins. By comparing different fin geometries, the thermal performance and airflow are compared and analyzed. It was found that the airfoil fins with reverse orientation offers the minimum resistance. Airfoil is the most commonly used shape in applications where aerodynamics is of major importance
