摘要
不当的商业照明所产生的光污染,会对行人造成视觉不舒适。本研究采用实地调研法,在商业照明区内随机选出9条商业街道,分别由10个被试者在商业街上行走观测,自由选择出2个舒适和2个不舒适的夜间商业标识。从360个商业标识中筛选出至少有两人一致认为其舒适(36个)或不舒适(32个)的,并将其作为光色和照明等参数实地测量的对象。使用成像亮度计拍摄商业标识的亮度分布图,单反相机记录色度照片,照度计测量周围环境照度。商业标识技术参数和行人视觉舒适度相关性分析结果表明,在商业标识的16个光色和照明参数中,亮度、颜色、频闪、视觉分辨率相关的参数是影响行人视觉舒适度的潜在因素。
The light pollution caused by inappropriate commercial lighting will cause visual discomfort to pedestrians.This research adopts the method of field investigation.Nine commercial streets were randomly selected in the commercial lighting area.Ten participants walked on commercial streets and two comfortable and two uncomfortable night commercial signs were chosen freely.36 comfortable and 32 uncomfortable billboards,each chosen by at least two people,were picked out from the 360 commercial signage as the objects of field measurement of light,color and lighting parameters.The image brightness meter is used to photograph the brightness distribution of commercial signage,the single-mirror camera records the chroma photos,and the illuminometer measures the ambient illumination.The results of correlation analysis between technical parameters of commercial signage and visual comfort of pedestrians show that seven parameters related to brightness,color,dynamic scintillation and visual resolution are the potential factors affecting the visual comfort of pedestrians among 16 light-color and illumination parameters of commercial signs.
