摘　　要： 公共场所照明具有全天候、多应用、能耗大的特点;掌握任意时间的天空亮度分布情况是充分利用自然光、实现智能照明的基础;基于国际照明委员会(CIE)给出的天空亮度计算公式,建立自然光对公共照明区域产生的天空照度模型;引入数学和光学相关原理建立公共场所人造光和自然光的混合模型;利用改进蚁群算法求解模型,得出最佳的灯具亮度组合,实现舒适和及节能的综合最优;最后,选择典型的大跨度带天窗建筑物为采光对象完成仿真实验,实验结果验证该策略的有效性。 Locus lighting has the characteristics of all-weather operation,variable demand and large energy consumption.Knowing the distribution of sky luminance at any time is the foundation to make full use of natural light and realize intelligent lighting.Sky illumination model was established based upon formula for calculating sky brightness from the International Commission on Illumination （CIE）.A hybrid model of combining artificial light with natural light was established using optical principles.The best combination of lighting fixtures luminance is solved out by use of the improved ant colony algorithm,hence realizing the comprehensive optimum of comfort and energy-saving.Finally,the effectiveness of control strategy was verified by simulation of large span building.
