反射器对氙灯工作性能影响的实验研究

摘要

Focusing on the design and running condition of the reflectors in the lamp boxes,an experiment has been designed to confirm the quantization of the reflector's influence on the flash lamps radiation and neodymium glass fluorescence.The flash lamp radiation is measured by the high current diode.The neodymium glass fluorescence is recorded by the measurement system designed and manufactured by ourselves.Meanwhile,a high speed camera is used to observe the discharge channel.Results indi-cate that the reflector can improve the flash lamp radiation by 89% and the neodymium glass fluorescence by 78%.More impor-tant,the reason of flash lamp's"turning white"while running has been found.The reflector will induce the discharge channel forming near the reflector,making the lamp wall near the reflector be ablated excessively.%针对灯箱中反射器的设计和运行情况,设计实验量化了反射器对氙灯辐射和钕玻璃荧光效率的影响.氙灯辐射由强流管测量的氙灯辐射波形和能量计测量的辐射能量获得;钕玻璃荧光由自主设计的荧光测量系统获得;同时,使用高速摄影仪对放电通道进行观测.实验发现,反射器在此次实验条件下可以提高氙灯辐射效率89%,提高钕玻璃荧光效率78%.而且,实验发现工程运行中氙灯"发白",是反射器引导氙灯放电通道在靠近反射器一侧形成,导致该处过度烧蚀的结果.
