摘要
光源的选择是设计太阳模拟器的重要内容。本文通过对普通卤钨灯、镀膜卤钨灯及一种特殊金属卤化物灯——新型镝灯的测量试验研究，指出了单层膜和多层膜的卤钨灯由于其红外部分能量占总能量的比例过大，用这些卤钨灯作全光谱太阳模拟器光源是不合适的。所选用的新型镝灯是全光谱太阳模拟器的一种理想光源，光源的相对光谱能量分布失配误差在部分波长内满足A级模拟器的要求，在250—2500肿波长范围内皆能满足B级模拟器的要求。
The selection of light sources is very important in the design of whole spectrum solar simulators. The investigation was conducted about the spectrum of no-film, single-film and multi-film halogen-tungsten hghts and a new type of dysprosium light. It has been showed that the halogen-tungsten lights are not suitable for the solar simulator since their infrared energy accounts for a much great portion in the total radiation and their technical performance is below the C level of the national standard. In contrast with that, the dysprosium light is an excellent light for the full spectrum solar simulator. The disorder error index of its relative spectrum energy can reach the A level of the national standard in the wave length range of 250 - 400nm and 700 - 1000nm while the index reaches the B level of the national standard in the broader spectrum range of 250 0 2500nm.
