摘要
随着城乡建设加快和夜经济的发展,城镇照明建设的重要性越发凸显,在满足功能需求的基础上,仍需进行合理的照明规划,选择适合的照明方式和灯具参数。白光LED光效高,在城镇道路照明中已广泛应用,正逐步取代传统色温较低的高压钠灯,但也存在不舒适眩光等视觉问题和短波比例增加等节律违和问题。以北京为例,随机测得道路照明色温范围较宽(1600~5400 K),对于各色温区间,具有统计学意义的行人道路光色偏好尚未可知,亟需从多视角开展研究。本研究从行人的视觉感受和心理偏好出发,开展跨感官通道研究,挖掘路灯色温、地面照度、环境温度的视觉心理影响,在驾驶安全的核心视角外,提供行人的人因视角数据支撑。本研究选取了6种色温、3种照度组合的18种城镇道路照明素材,通过行人视角的视频,在3种环境温度下开展评价实验。结果表明,不同的照明色温带来不同的视觉心理感受,色温、照度和温度对行人的心理偏好存在交互作用,环境温度越高,被试对于中高色温的评价越好。
With the acceleration of urban and rural construction and the development of the night economy,the importance of urban lighting construction is becoming more and more prominent.On the basis of meeting functional needs,it is still necessary to carry out reasonable lighting planning,and choose suitable lighting methods and parameters.White LED with high light efficiency,which has been widely used in urban road lighting,is gradually replacing the traditional high-pressure sodium lamp of low color temperature,but there are also visual and rhythm problems such as uncomfortable glare and short-wave ratio increases.In Beijing,for example,the randomly measured street light color range is wide(1600~5400K),for each color temperature range,statistically significant light color preference of pedestrians is not yet known,so that research from multiple perspectives is urgently needed.In this paper,a cross-sensory channel study was conducted from the visual perception and psychological preference of pedestrians to explore the visual-psychological effects of street light color,ground illuminance,and ambient temperature,and to provide data support from the human factors'perspective of pedestrians in addition to the core perspective of driving safety.In this study,18 urban street lighting materials with 6 color temperatures and 3 illuminance combinations were selected,and evaluation experiments were conducted at 3 ambient temperatures through videos of pedestrian perspectives.The results show that different lighting color temperatures bring different visual psychological perceptions,and there is an interactive effect of color temperature,illuminance and temperature on pedestrians'psychological preferences;the higher the ambient temperature,the better the participants'evaluations of medium and high color temperatures.
