摘　　要：氙灯的辐射光谱与日光接近,可用作模拟日光和人工老化的光源。针对在聚光类太阳能热利用技术及其装备的研究开发过程中需要高热流密度太阳辐射的情况,为降低研发成本和加快研发进度,提出了利用基于超高压短弧氙灯的探照灯来模拟高聚光比太阳辐射的做法,进而开发出一种中高温加热用聚光器,并对其进行了照射加热试验。试验结果表明该新型聚光器可以达到太阳能中高温利用所需的温度,其输入功率的热利用率可达50%以上,可以大大降低相关设备的研制费用及加快研发的进度。Radiation spectrum of xenon lamp is close to sunlight which is used to be a lamphouse for sunlight modeling and aging. A high heat flux is required in the research and development process of concentrated solar radiation utility. In order to reduce the price and shorten the cycle of research, a novel plan was put forward of using searchlight base on short arc xenon lamp to replace reflectors and attached automatic tracking system to model concentrated solar energy. Experiment results showed that concentrator can heat storage unit to middle and high temperature of solar energy utility, it＇s total energy utility ratio was as more as 50% when it was improved by some ways, while it＇s cost was very cheaper.
