为了使人们在地下室等一些特殊环境下享受健康、绿色的自然光照明,更好地利用太阳能资源,提出一种基于两级定位跟踪的自然光导光照明装置设计方案.通过采用粗级跟踪和精确跟踪两级定位跟踪模式和在系统的机械传动机构中采用谐波传动方式等措施,由此来提高系统的跟踪稳定性和跟踪精度;同时,对聚光单元进行改进设计,以及在照明灯具处增设智能调光功能,以此进一步提高系统的光利用率和光强稳定性.实验测试表明,系统能获得较好的照明品质,具有一定的应用价值.
To make people enjoy the healthy and green natural lighting in some special environments such as basement and better utilize solar energy resources,a scheme of guiding light illumination device based on two-stage location-tracking mode is designed.The system employs two-stage location-tracking mode (coarse tracking and precise tracking model) to improve the tracking accuracy and adopts the harmonic drive in mechanical driving mechanism to improve the tracking stability.In addition,the system further increases the availability ratio of light and enhances the stability of light intensity by optimally designing the collector and adding the function of intelligent dimmer in lighting lamps.The experimental results show that the system can achieve good lighting quality and has certain value of application.
