摘要
目的研究在光环境设计中,合理利用天然采光和人工照明并与建筑的功能、形式有机地结合,创造宜人的光环境.方法应用灯具的配光曲线原理,通过实地测量和分析评价,运用照度的计算方法,结合人机工程学原理,对建筑大学图书馆的照度及眩光进行评价,得出影响光环境质量的因素.结果对于大跨度公共阅读工作区来说,在保证通过良好的朝向来获取自然光线的前提基础上,中庭间接采光在最大进深约5 m的范围内,可弥补仅靠侧窗采光的不足,对光环境中最重要的照度因素起到补充作用.另外,桌面材料的反射系数越小,其反射照度曲线的照度值分布越均匀,桌面颜色过深还会导致读者在阅读中产生眼疲劳.结论为图书馆光环境的设计提供新的数据依据,优化光环境质量,使"人一机一环境"系统达到和谐统一,为读者营造舒适、高效的学习环境.
On the light environment design,this paper applies the principles of lamp light distribution curve and makes rational use of natural lighting and artificial lighting integrating the buildings′ function and form in order to create a pleasant light environment.The paper applies the lamp light distribution curve through field measurement and evaluation analysis,using calculation method of illumination,combining with ergonomics principles,to evaluate the illumination and glare on Shenyang Jianzhu University library and conclude the influence factors to the quality of light environment.For large span library,on the premise of obtaining natural lighting through a good orientation,the atrium indirect daylight can make up for the shortage of side lighting and play a complementary role in indoor illumination in the maximum depth about 5m.In addition,if the reflection coefficient of desktop material is smaller,the light reflection illumination curve distribution will be more uniformed.And if the desktop color is too deep,the readers will be lead to eye fatigue.We provide new data to make the optical quality better and make the man-machine system achieve the harmonious unification,for readers to create a comfortable and efficient learning environment.
