摘　　要：以公共建筑地下车库中最常采用的采光井为研究对象,通过模拟仿真方法对比分析不同采光井设计因素对采光效果的影响。研究表明:受到构件性能限制,当采光罩玻璃透射比提升至80%以上或采光井墙体倾斜角减少至45°以下,参数变化对采光效果影响甚微;采光井井口尺寸是影响采光效果的主要因素,研究通过拟合得出两者间的关系式,为采光井设计提供计算参考。The lighting wells most commonly used in underground garages of public buildings are taken as the research object,and the effects of different lighting well design factors on the lighting effect are compared and analyzed through simulation methods.The research shows that:due to the limitation of component performance,when transmittance of the glass of the lighting cover is increased to more than 80%or inclination angle of the wall of the lighting well is reduced to less than 45°,the parameter change has little effect on lighting effect;the size of the wellhead of the lighting well affects lighting effect,and the relationship between them is obtained by fitting,which provides calculation reference for design of lighting well.
