摘要
当天空亮度不足时,为了使天幕靶正常工作,需要为天幕靶配备人工光源。针对JYJ 90型天幕靶视场范围的特点,设计了一种基于高亮白色聚光圆头发光二极管的弧形线状LED光源。实验结果表明该光源可以保证天幕靶的正常工作,并且可以增加天幕靶的灵敏度,提高天幕靶的分辨力。该光源性能稳定、携带方便、结构简单。
When the brightness of the sky is not bright enough for the skyscreens working normally,the artificial light source is very important.According to the characteristics of JYJ-90 skyscreens field of view（FOV）,an arc linear LED light source was designed based on white light emitting diode.The test results showed that the light source can make the skyscreens work normally,and it improved the sensitivity and resolution of the skyscreens.This light source has stable performance and simple structure for easy carry.
