Abstract：Under high-power operating conditions,stage lights are prone to shutter overheating and shortened service life.To address this issue,this paper proposes an efficient cooling solution based on the synergy of surface coatings and structural design.A high-reflectivity coating is applied to the light-incident surface of the shutter blade to reduce light absorption,while a high-emissivity heat-dissipation layer is designed on the back surface to enhance radiative heat dissipation.At the same time,a curved guiding mechanism is introduced to dynamically distribute the illuminated area on the shutter blade,avoiding long-term localized heating.Experimental and simulation results show that this scheme can reduce the overall temperature of the shutter blade by approximately 180℃and maintain stability during a 320 h aging test.The curved guiding structure further reduces local temperatures by 30～50℃,effectively slowing down thermal failure.The results provide a feasible approach and theoretical reference for efficient heat dissipation and long-lifetime applications of stage light shutters.
