摘　　要：为了使用太阳能资源实现对封闭建筑物的照明,利用菲涅尔透镜、全反射原理,利用太阳方位角及光传感器的双闭环控制原理,利用基于ARM单片机的控制器对采集器的运动、追踪模式及电能利用进行控制,实现运动的精确控制和能源的优化利用,并通过光导纤维将太阳光实现导入室内照明。在此基础上对光的汇聚、传导效率、光损耗、装置散热、电气性能等因素进行了分析计算,实验结果表明:实验发光装置发光光源稳定,导入后的光效率达到60.9%以上,且散热效果良好,同时对太阳光追踪精度可达0.002°。In order to use the solar energy resources to illuminate the enclosed buildings, it makes use of fresnel lens,total reflection principle, sun azimuth,the double closed-loop control principle of light sensor, and utilize controller based on ARM single chip microcomputer to control the movement, direction tracking mode and electricity using of collector, achieve precise control of movement and optimize the use of energy, and through the optical fiber sunlight to achieve indoor lighting.On this basis, analysis and calculated the factors such as light convergence, conduction efficiency, light loss, device cooling, electrical performance and others. The experiment results show that the light source of the light-emitting device is stable and the light efficiency after imported reaches more than 60.9%, and good effect in cooling, while tracking sun’s accuracy up to 0.002°.
