摘要
为了更好地利用太阳能资源,提出一种基于智能调光的光纤导光照明系统设计方案。通过对集光器进行优化设计、采用两级定位跟踪模式来提高太阳自动跟踪器的跟踪精度等措施,系统能最大程度地将太阳光导入到光纤以提高系统的光利用率;同时,通过提高跟踪器的跟踪稳定性和增设智能调光功能等措施,使之能克服天气多变、跟踪抖动等因素所导致的光强波动问题,系统的光强稳定度得到了提高。实验测试表明,系统可以获得较好的照明品质,具有一定的应用推广价值。
In order to better utilize the solar energy resource,a design scheme of fiber light transmitting illumination system with intelligent dimming function is proposed.The system can import the sunlight into the optical fiber to the maximum extent to improve its light utilization efficiency by means of the optimal design for optical collector,and two?stage positioning and tracking mode for improvement of tracking accuracy of sun auto?tracking device.The improvement of the tracking stability of tracker and addition of the intelligent dimming function can make the system overcome the light intensity fluctuation caused by changeable weather and tracing shake,and improve the stability of light intensity.The experimental results show that the system can obtain high illumination quality,and has a certain application and promotion value.
