摘　　要：光纤光导系统是一种利用柔软光纤将室外阳光引入室内进行照明的技术,不涉及能量形式转换,太阳能利用效率很高,是一种新型的太阳能利用模式。研制了基于菲涅尔透镜和PMMA光纤来聚光传输的光导系统,并设计了光纤水冷结构来解决高温下光纤烧毁问题。通过在西藏地区室外实际运行测试表明:该系统能够在高辐照地区精确地跟踪太阳,稳定有效地将太阳光传输至室内照明,并且光纤最终的输出光谱与太阳光谱相近,不会在可见光波段造成畸变,可以为室内提供舒适、安全的自然光照明,系统总体效率可以达到15%。As a novel high-efficient application technology of solar energy,optical fiber daylighting system transmits concentrated daylight indoors via fibers without energy conversion.We design a daylighting system based on the Fresnel lens and PMMA optical fiber and build a water-cooling structure to prevent fiber burning at high temperature.Outdoor tests of the daylighting system in Tibet show that the system accurately tracks the sun in high-radiation areas and transmits sunlight to indoor lighting stably and effectively.Moreover,the final output spectrum of the optical fiber is similar to that of the sun,without causing distortion in visible band,and can provide comfortable and safe natural lighting for indoor.The overall efficiency of the daylighting system reaches 15%.
