书架照明的节能优化设计研究

Research on Energy-saving Design of Book Stacks Lighting

图书馆建筑书架照明不仅要满足《建筑照明设计标准》GB 50034—2013对照明数量、质量的要求,还应实现设计节能。本文选取7款不同的灯具配光应用在典型行道宽度的书架照明中,通过模拟计算比较研究了不同行道宽度时灯具配光的三个指标——光束角θ、光强比I_(max)/I_(30)、区域光通比η_(4,5,6)与光通利用率U的关系,最终提出书架照明节能优化设计时灯具配光选型的建议,以及灯具光通量参考值和书架垂直面照明功率密度参考值。

Lighting for book shelf is not only evaluated with the lighting quantity,quality requirements on Libraries in GB 50034—2013 Standards for lighting design of buildings,but also should be energy efficient lighting.7 different types of IES photometric data are chosen with application in the shelf lighting with typical aisle width.This paper concentrates on the relationships between the three parameters of optical performance—beam angle θ,the ratio of Imax/I30,proportion of flux in the solid angle zones of 30° ～ 60°width η4,5,6,and utilance U.The reference value of optical performance,the luminous flux,LPD is proposed eventually for energy-saving optimization design.
