摘　　要：为了克服现有绿色建筑外遮阳系统在进行遮阳的同时会影响室内自然采光效果的缺点,同时也为了减少白昼期间的电能消耗,将光纤光导照明技术与智能遮阳技术结合改进,通过在外遮阳板上间隔交替布设若干小型化的自然光采集单元以及在每组外遮阳板中心位置设置追光控制传感器,通过智能追光控制,使得外遮阳系统跟随入射光线角度旋转,始终与入射光线保持垂直关系,相应地,附设在外遮阳板上的自然光采集单元也与入射光线保持垂直入射,系统由石英光纤将采集聚焦后的光线传输至室内自然光与LED混光照明灯具进行照明.试验研究表明,智能追光控制使得遮阳板的遮阳效率得到提高,可以减少空调电力能耗;同时自然光利用率也得到改善,测试研究显示,能够使建筑全年自然光可利用率提高至75%,可减少室内照明电力能耗.智能外遮阳与自然采光集成系统为建筑节能和绿色可持续运营提供了其中一种技术解决方案.In order to overcome the shortcomings of the existing green building external shading system which affected indoor day-lighting while shading,and to reduce power consumption during the daytime,fiber and optical lighting technologies were combined and improved with intelligent external shading technologies.Several miniaturized light acquisition units were alternately arranged on the external shading board,and tracing control sensors were set in the central position of each group of external shading panels,to make the external shading system rotate with the incident light angle through the intelligent light tracing control,keeping it vertical to the incident light angle.Accordingly,the light acquisition units integrated on the external shading board were also vertical to the incident light angle.It transmitted the collected and focused lights to indoor natural light LED mix lamps for lighting.The research results show that the intelligent light tracing control can improve the shading efficiency,cut air conditioning power consumption,and improve daylight availability ratio.The test results show that it can improve the daylight availability ratio of the year to 75%,reducing illumination power consumption.The intelligent integrated system provides a technical solution for building energy saving and green sustainable operation.
