具备太阳追踪功能的室内采光系统设计及实验

Design and Experiment of Indoor Daylighting System with Solar Tracking Function

由于建筑的缺陷,全北或地下室房间一直无法采集到阳光,对长期居住的人身体造成影响。针对这一现状,设计了一种基于光纤传输的室内自动采光装置。该装置能够自动跟随太阳光发生自转,利用凸透镜对太阳光进行聚集,通过塑料光纤进行传导,使太阳光漫射到住户家中。通过实验对阳光的聚集、传导效率和损耗等因素进行了研究。该装置中聚光装置采集光源稳定,太阳光追踪装置精度、性能良好,塑料光纤短距离传输光能良好,传输光的光照强度可以满足用户日常照明需求。

Due to building defects,all-north or basement rooms have not been able to collect sunlight,which will affect the body of long-term residents.Therefore,an indoor automatic daylighting device based on optical fiber transmission was designed,which can automatically follow the sunlight to rotate,use convex lenses to gather the sunlight,conduct it through the plastic optical fiber,and diffuse it into the households.This paper studied the light concentration,conduction efficiency and loss and other factors through experiment.The optical block of the device has a stable collection light source,the solar tracking device has good accuracy and performance,the plastic optical fiber can transmit light in a short distance,and the light intensity of the transmitted light can meet the daily lighting needs of users.
