Abstract: Objective:To investigate the optical design effect of a new type of LED surgical light on navy ships.Methods:With Lighttools, an optical simulation software, the design of the total internal reflection (TIR) lens was optimized, the lighting characteristics of the surgical light on navy ships were analyzed, and the lighting effect of such design in the onboard operating room was simulated.Results:A TIR lens can efficiently collect 78% LED light. After secondary design, the central illuminance of the light spot of the LED lamp beads reached 9.1 klx, that of one single light was 42.5 klx, and that of the lighting system was 200.0 klx. The spot diameter of the surgical light used on navy ships was 238 mm with a uniform spot distribution.Conclusion:The lighting indicators of the new LED surgical light with TIR lens designed for navy ships can meet the industry standards.
