摘要目的:探讨新型LED舰用手术灯的光学设计效果。方法:采用光学模拟软件lighttools，开展了全内反射(TIR)透镜的优化设计，以及舰用手术灯的照明特性分析，并对舰艇手术室照明效果进行了模拟。结果:TIR透镜能够高效收集LED光线，收集率可达78%。经过二次光学设计，LED灯珠的光斑中心照度可以达到9.1 klx，单灯为42.5 klx，照明系统为200.0 klx。舰用手术灯的光斑直径为238 mm，光斑分布均匀。结论:基于TIR透镜的新型LED舰用手术灯的照明指标能够满足行业标准要求。

abstractsObjective: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.
