ABSTRACT

Many models of discomfort glare have been proposed for outdoor lighting applications. Most of them were built from data collected in the laboratory in static situations, with motionless light sources, which main characteristics (luminance, size and position) were constant over time. However, on the road at night, drivers are moving with multiple sources around them. To fill the gap between static situations and more realistic ones, four psychophysic experiments were carried out in a laboratory to investigate the impact of the cyclic variations of several light source characteristics (its luminance, eccentricity and solid angle) on the discomfort glare. The temporal frequencies have been chosen representative of outdoor lighting conditions, up to 2.6 Hz. No impact of the dynamics of the glare source was found, except for a source with variable luminance at a low frequency ($f=0.65Hz$).

摘要

已经针对户外照明应用提出了许多不适眩光模型。它们中的大多数是根据在静态情况下在实验室收集的数据构建的，具有静止的光源，其主要特征（亮度、大小和位置）随着时间的推移是恒定的。然而，在夜间的道路上，司机们在他们周围有多个来源移动。为了填补静态情况和更现实情况之间的空白，在实验室进行了四项心理物理学实验，以研究几种光源特性（其亮度、偏心度和立体角）的循环变化对不适眩光的影响。已选择代表户外照明条件的时间频率，最高可达 2.6 Hz。没有发现眩光源的动态影响，$F=0.65Hz$）。
