Abstract：With the widespread application of high-power LED luminaires in industries such as industrial and road lighting,heat dissipation has become a core bottleneck restricting the improvement of luminous efficiency and extension of lifespan.Graphene,with its superior thermal conductivity,has significant advantages in the field of heat dissipation materials.Applying it to the heat dissipation system of high-power LED luminaires holds important engineering value and scientific research significance.This paper focuses on the measurement method of the heat dissipation performance of graphene high-thermal-conductivity films,systematically studies the structural design of the graphene heat dissipation system for high-power LED luminaires,and primarily explores precise measurement methods.By combining theoretical analysis,structural optimization,and experimental testing,a heat dissipation system model is constructed,and an efficient and precise measurement scheme is proposed.Experiments show that the designed graphene heat dissipation system can effectively reduce the operating temperature of the luminaires,stabilizing the junction temperature to as low as 62℃,a reduction of 23℃compared to traditional aluminum alloy heat dissipation systems.The measurement method error is controlled within 5%,accurately reflecting the heat dissipation characteristics of the film.The research results provide theoretical support for the optimal design of heat dissipation systems and offer a reliable measurement method for evaluating the heat dissipation performance of films.
