摘　　要：对于低压高强大功率紫外线灯,汞齐在灯中的应用与设计尤为重要。本文简述了汞蒸气压影响紫外线灯紫外输出的机理,简要介绍了汞齐的主要性能参数与获得汞齐温度特性的方法,介绍了包含国内外主流“贴装汞点”汞齐紫外线灯技术在内的3种汞齐方式灯的构造。依据前人理论基础,通过实验测得了T5(管径15 mm,内径13 mm)、T6(管径19 mm,内径17 mm)灯中相对紫外输出随液汞和开发的几款汞齐位置温度的变化关系。得出T6管径灯的紫外输出最大时对应冷端温度≈42℃,对应汞蒸气压≈0.94 Pa;T5管径灯的紫外输出最大时对应冷端温度≈44℃,对应汞蒸气压≈1.09 Pa。探讨了汞齐紫外线灯的设计思路,给出了汞齐紫外线灯研制流程并结合实际优化了工艺流程。For low-pressure high-power UV lamp,the application and design of amalgam in the lamp is particularly important.This paper briefly describes the mechanism of mercury vapor pressure affecting the UV output of UV lamp,briefly introduces the main performance parameters of amalgam and the method to obtain the temperature characteristics of amalgam,and introduces the three structures of amalgam lamps including the mainstream"Mercury point"amalgam UV lamp technology at home and abroad.Based on the theoretical basis of previous studies,the variation of relative UV output in T5(tube diameter 15 mm,inner diameter 13 mm)and T6(tube diameter 19 mm,inner diameter 17 mm)lamps with liquid mercury and the position temperature of several amalgams developed weremeasured experimentally.It is concluded that the maximumUV output of T6 lamp is achieved when the cold end temperature is about 42℃,and the corresponding mercury vapor pressure is about 0.94 Pa;and that the maximum UV output of T5 lamp is achieved when the cold end temperature is about 44℃,and the corresponding mercury vapor pressure is about 1.09 Pa.The design idea of amalgam ultraviolet lamp is discussed,the development process of amalgam ultraviolet lamp is given,and the process flow is optimized combined with practice.
