| 摘 要： | 为了寻找在低照度的城区照明中能准确反映行人真实外表及自然程度的立体感造型指标,分析了垂直面照度与半柱面照度比值、垂直面照度与水平面照度比值、平均柱面照度与水平面照度比值三个常用的立体感评价指标,并对重庆三峡广场步行街的这三个立体感评价指标进行了测量计算。结果表明,垂直面照度与水平面照度比值和平均柱面照度与水平面照度比值的变化规律相似,均是随测点位置的改变而改变,并在两灯之间步行街轴向的中部达到最大值,垂直面照度与半柱面照度比值随测点位置的变化较小,更适合作为城区照明光环境的立体感照明质量评价指标。

| Abstract: | In order to find out a space sense indicator that can present the real appearance of human and natural in urban lighting environment,three common used indicators are studied,which are ratio of vertical illuminance to semi-cylindrical illuminance,ratio of vertical illuminance to horizontal illuminance and ratio of average cylindrical illuminance to horizontal illuminance.An on-site test is taken at Three Gorges Square Pedestrian Street of Chongqing.The variation law of ratio of vertical illuminance to horizo... |
