摘要：
Light pipe illumination is a new technology in the field of building energy conservation with the advantages of safety,high efficiency and saving construction cost.It has application value that improves lighting effects and saves lighting power consumption in large teaching building project. Aimed at the design of green lighting technology for light tunnel in large teaching building,the structure of the light pipe is designed,the principle of the green illumination of the light pipe is expounded,the conduction efficiency of the light pipe is calculated.According to the transmission efficiency of the light guide and local illumination conditions in Jinan City,with the methods of field investigation,literature analysis and empirical research,the paper makes the design of green lighting technology of application in the art teaching building project.According to the design requirements of the illumination, the technology of solatube was used in the project. The incremental benefit evaluation and lighting effect of green lighting technology was analyzed in the process of using in the teaching building.The results show that the green light guide lighting technology achieves the zero energy consumption during the time of 7:20-17:00 in winter in the exhibition hall on the first floor and the lobby on the second floor.The average brightness reaches 329.91Lux and 312.71 Lux,the annual electricity savings of teaching building is more than 189000 kw·h,so the effects in energy-saving and emission-reduction is siguificant.%光导管照明技术是建筑节能领域的一种新兴技术,具有安全、高效、节约建筑用电成本等优势,在大开间教学楼项目中具有提高照明效果,节约照明耗电的应用价值.针对大开间教学楼进行光导管绿色照明技术的应用设计,文章设计了光导管的结构,阐述了光导管绿色照明技术原理,计算了光导管的传导效率,根据光导管的传导效率并结合济南市当地的光照条件,通过文献阅读、实地调查和技术研究等方法,按照山东建筑大学艺术教学楼照度设计的要求,对项目进行了光导管绿色照明技术应用设计;对光导管绿色照明技术在教学楼使用过程中的照明效果和增量效益进行了评估分析.结果表明:光导管绿色照明技术实现了教学楼一层展厅、二层门厅冬季7:20-17:00时间段的日间零能耗照明零能耗照明,照明亮度平均值分别达到了329.9和312.7 Lux,教学楼年节约电能189000 kW·h,节能减排效益明显.
