反射器对氙灯工作性能影响的实验研究

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 indicate that the reflector can improve the flash lamp radiation by 89% and the neodymium glass fluorescence by 78%. More important, 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.
