摘　　要：目的:研制新型直升机水下逃生照明指示灯。方法:对第一代水下灯进行改进,并进行性能测试及试验。结果:水下灯物理性能和使用性能均符合产品设计要求;系统总有效工作时间>3 h,应急水下连续照明指示时间>20 min;可视距离:照明灯>3 m,指示灯>1 m,指示灯频闪频率60次/min;系统水密性≥0.2 MPa。结论:改进后的水下灯比第一代水下灯在各项性能上都有了明显的提高。Objective： To devdop a new type of underwater exit light. Methods： The first generation underwater exit light was improved, and its performances were tested. Results： The physical and the functional performances of improved underwater exit light were consistent with requirement of design. The total active working time was longer than 3 hours, and the continuous illuminating time, longer than 20 minutes. The visible distance of illuminating lamp was farter than 3 meters, and the visible distance of indicator lamp, farter than 1 meter. The twinkling frequency of indicator lamp was 60 times per minute, and its waterproof performance was not less than 0.2 MPa. Conclusions： Compared with the first generation underwater light, the improved underwater light has an obvious exaltation on various functions.
