摘要
提出一种采光面积大、结构简单、制作容易、维修方便的平面反光镜阵列汇聚采光,导光管传光,平面镜耦合,磨砂塑料盘散光的新型太阳光照明系统。考察了该系统的平面反光镜聚光特性,导光管的耦合方法及导光管透光率随光线入射角、导光管长度和导光管直径的关系。利用该系统,研究了透射光光强随导光管长度的变化规律、0.72M长导光管在不同集光比下的导光性能以及一天中聚光与不聚光条件下导光管透光率比较。结果表明,采用本系统汇聚阳光使进入导光管光线的入射角可以调整,入射角角度都比较小,从而使光线在导光管中的反射次数减少,光损失少,一天中光照亮度均匀。
A novel solar illumination system consisting of strip plane mirror array collecting sunlight, light pipe, coupling mirror and grinded plastic tray scattering light was introduced. The system has a big collecting sunlight area, simple structure, easy manufacture and convenience maintenance. The gathering light performance of plane mirror, coupling method of light pipe and light permeance rate in different incidence angle of light ray, length and diameter of light pipe was studied. With the system, light intensity in different light pipes and gathering light rate were studied. The results showed that the incidence angle of light ray in light pipe can be adjusted in the system so that the brightness is even in a day.
