Analysis and Optimization of Heat Dissipation Performance for High-power LED Downlights
Thermal failure remains a critical factor affecting the performance of high-power LED downlights.This paper conducts thermal analysis using the fluid analysis software FloEFD on a 40 W high-power LED downlight model,compares and evaluates the heat dissipation performance of three different heat sink designs:honeycomb,cylindrical,and finned heat sinks.The results indicate that the finned heat sink performs best among the three models,with its heat dissipation effectiveness primarily influenced by fin thickness and spacing.By optimizing the heat sink structure,it is possible to significantly enhance the heat dissipation efficiency of high-power LED downlights and extend their operational lifespan.
