摘　　要：在老龄化背景下,老旧住宅交通空间的照明环境对于老年人的视觉安全性有重要影响,为研究照明环境的相关要素与老年人视觉安全性的影响规律,选取40名被调查者,采用语义差别法对107组实景照片进行主观安全性评价,对地面水平照度、墙面垂直照度、地面照度均匀度、一般显色指数、色温笔进行相关性分析。并且基于现存问题进行DIALux软件优化设计,据此初步明确各指标的数值范围,并建立优化模型以表现效果,提出老旧住宅公共交通空间照明质量指标优化策略。研究表明:地面水平照度、墙面垂直照度、地面照度均匀度与视觉安全性呈较为显著的正相关。其中地面水平照度宜大于150 lx,墙面垂直照度宜大于60 lx,地面照度均匀度宜大于0.6,最好大于0.8。因此,现有老旧住宅交通空间照明环境设计需更具针对性,以获得适应老年人视觉特征的照明环境。In the context of aging,the lighting environment of transportation spaces in old residential areas plays an important role in the visual safety of elderly individuals.In order to study the impact of various lighting elements on the visual safety of the elderly,40 participants were selected for the survey.The semantic differential method was used to assess the subjective safety of 107 sets of real-life photos.A correlation analysis was conducted on factors such as horizontal illuminance on the ground,vertical illuminance on the walls,uniformity of ground illuminance,general color rendering index,and color temperature.Based on the existing issues,an optimization design was carried out using DIALux software.This helped to preliminarily define the value ranges for various lighting indicators and establish an optimization model to visualize the effects.The study also proposed strategies for optimizing the lighting quality indicators of public transportation spaces in old residential areas.The results indicate that horizontal illuminance on the ground,vertical illuminance on the walls,and ground illuminance uniformity have a significant positive correlation with visual safety.Specifically,horizontal illuminance on the ground should be greater than 150 lx,vertical illuminance on the walls should be greater than 60 lx,and ground illuminance uniformity should be greater than 0.6,ideally exceeding 0.8.Therefore,the current lighting design of transportation spaces in old residential areas needs to be more targeted to create lighting environments that better accommodate the visual characteristics of elderly individuals.
