摘要
对比显示系数q;是隧道照明察觉对比法入口段亮度计算公式中的重要参数之一,q_(c)与公路隧道照明灯具安装方式有关。通过文献整理,从照明方式、光源选择和灯具配光曲线、灯具布置方式(灯具间距、灯具挂高、灯具偏转角、灯具俯仰角)和隧道内光的多次反射(墙面反射系数、路面反射系数)等方面分析隧道照明中灯具安装相关问题,并将此综述成果作为后续系统研究对比显示系数和隧道照明设计方法的依据。
The contrast revealing coefficient q_(c) is one of the most important parameters in the threshold zone luminance calculation equation based on the perceived contrast method,q;is related to the luminaire installation form in road tunnel lighting.According to literature analysis method,scientific questions related to the luminaire installation form can be considered from the following aspects:lighting form,light source selection,light distribution curve,luminaire arrangement and multiple reflections of light inside the tunnel.Luminaire arrangement includes luminaire spacing,luminaire hanging height,luminaire deflection angle and luminaire pitch angle.Multiple reflections of light inside the tunnel can be measured by wall reflection coefficient and pavement reflection coefficient.This review can be used as a basis for subsequent systematic research on contrast revealing coefficient and tunnel lighting design methods.
