摘　　要：为满足某深空探测器的室内太阳辐照试验需求,研制大型室内光照环境模拟系统。采用大功率金属卤化物灯、卤钨灯,配套高精度、小发散角投光灯具,在试验场内单面墙体前垂直布置,实现20m×20m超大辐照面积内与太阳光谱相匹配的均匀照明。设计结果表明,辐照面内平均辐照度为400.4W/m2,600~700nm和965~995nm两个谱段内辐照度分别为48.5W/m2和5.1W/m2,光线入射角连续可调,在15°、30°和45°时,辐照不均匀性分别达到±12.4%、±8.1%和±14.9%,被照明物体阴影清晰。经过验收测试,光照系统各项实测指标与仿真计算结果吻合,完全满足设计要求,已成功应用于型号试验。A large-scale in-door illumination environment simulating system was designed and developed by Beijing Institute of Spacecraft Environment Engineering for solar irradiation test requirement of a deep-space sensor. Metallic halide lamps and tungsten halogen lamps with good accuracy and small collimating angle lanterns,which are highpower and good-match with sunlight,distribute on the wall of the laboratory in order to make 20 m × 20 m area illuminating uniformity. Design results showed that, firstly, total average radiation intensity is 400. 4W /m2.Secondly,intensity are 48. 5W /m2 in 600-700 nm and 5. 1W /m2 in 965-995 nm. Thirdly,incident angle of the system range from 15° to 45°. Fourthly,uniformity with 15°,30° and 45° are ± 12. 4%, ± 8. 1% and ± 14. 9% respectively. Finally,shadow profile in the area is clear. Check and accept data match the design results very well and meet the specifications totally. The system has been used in laboratory test of the sensor successfully.
