This research investigates methods to enhance the performance of radial heat sinks in LED lighting systems, emphasizing the impact of different perforated fin designs on thermal resistance. The study uncover that larger perforation holes, particularly in annular and cylindrical fins, significantly reduce thermal resistance and improving heat dissipation compared to rectangular and pin fins. Furthermore, it highlight the importance of heat sink orientation, as it significantly influences cooling efficiency, particularly in real-world applications with varied LED fixture positions. The findings underscore the need for a comprehensive approach considering both fin design and orientation for optimal performance. Notably, certain orientations exhibit reduced sensitivity to fin perforations. A compelling outcome of this study is the potential for lighter and cost-effective heat sinks, with perforated fins reducing material usage by 10-30%, fostering eco-friendly and aesthetically pleasing LED designs. These findings collectively offer insights into improving heat sink performance in LED systems, focusing on perforation size, orientation, and material savings, ultimately benefiting the efficiency and sustainability of LED lighting.
