摘　　要：居住区的道路照明具有十分重要的作用,夜间照明能够为行人提供感知安全、障碍检测、识别他人的身份或意图等作用。本文通过对大连三个建设年代较早的开放式多层居住区的调研,采用实地测量与主观评价相结合的方法,探索此类小区的居民安全感及照度水平之间的相关性,分析居民感知安全的照明环境与现有环境之间的差异。调研发现,此类居住区多存在照度不均匀、眩光严重及照明能源浪费等问题,造成安全性评价较差。对各个方向的照度与安全性评价的相关性分析发现,水平方向照度对安全感的影响最大。根据研究结果得出了居住区照度水平的推荐值,并对安全性评价较差的路段进行了照明模拟优化。Road lighting in residential communities plays a very important role.Night lighting can provide pedestrians with a sense of security,obstacle detection and identification of people’s identities or intentions.This paper conducts filed investigations in three open residential communities with multi-storey buildings which built in several decades ago in Dalian.On-site measurement and subjective evaluation are introduced to explore the correlation between residents’sense of security and illuminance levels.Then,it analyzes the differences between safety lighting environment of residents’precision and the existing environment.This paper finds most of residential communities have problems such as uneven illumination,serious glare and energy waste,which result in poor safety evaluation.It also finds that the horizontal illuminance has the greatest impact on the sense of safety by analysing the correlation between illuminance in various directions and safety evaluation.According to the research results,the recommended value of the illuminance levels in the residential area is obtained,and the lighting simulation optimization is carried out on the road with poor safety evaluation.
