过渡照明是影响车行进出地下车库视觉舒适性和行驶安全性的重要因素.本文分析了地下车库的停车视距,计算出过渡区长度,并以南京某车库为例,选取夏至日和冬至日两天,利用DIALux软件计算车库入口处天然光照度,用时间—亮度曲线计算需要增设的人工照明,给出了设计示例,并展望了未来发展趋势.
Transition lighting is an important factor affecting the visual comfort and driving safety of vehicles entering and exiting underground parking garages.This article analyzes the parking sight distance in the underground parking garage,calculates the length of the transition zone,and takes a garage in Nanjing as an example.Two days,the summer solstice and the winter solstice,are selected.Using DIALux software,the natural illuminance at the entrance of the garage is calculated.The time-luminance curse is used to calculate the additional artificial lighting needed.The paper provides a design example and anticipates future development trends.
