摘　　要：为了分析光导管顶部采光能否满足建筑物一般作业要求,通过实验方法,分别测试了北京夏季两个典型天气条件下的光导管顶部采光性能,结果表明,晴天时,室内最大平均照度值为314.188 lx,最小值为54.996 lx;阴天时,室内最大平均照度值为138.596 lx,最小值为29.28 1x.根据《民用建筑照明设计标准》GBJ 133-90关于办公楼建筑、办公室、会议室照度要求规定,采用光导管顶部采光能够满足一般作业要求.因此,太阳光光导管顶部采光可以作为建筑物辅助照明装置,实现建筑物白天部分或全部替代人工光源,降低建筑物照明能耗.The lighting performance of top light pipe in summer of Beijing has been measured to analyze whether the top light pipe can satisfy the general job＇s lighting or not. The results showed that the indoor maximum and minimum average illuminance were 314.188 lx and 54.996 lx respectively in the sunshine day and which were 138.596 lx and 29.28 lx respectively in the cloudy day. According to the “Design Standard of Civil Building and Illuminance” GBJ 133-90, the top lighting performance can satisfy the lighting in office building, meeting room et al. Therefore, the top light pipe can be the accessorial illuminance equipment to substitute partial or total artificial light sources in daily life to decrease the energy consumption of lighting.
