从照明到形象——城市夜间灯光的嬗变与发展研究

From Illumination to Identity:A Research on the Evolution and Development of Urban Lighting

划分早期、近代、现代、当代四个历史阶段,从光源技术、应用场景、夜间生活、城市空间等多维视角出发,梳理不同阶段灯光在城市夜间的角色和功能演变进程,剖析其演变特点,总结出城市夜间灯光的“三个转向”,即空间转向、公共转向、功能转向,阐述灯光在当代城市夜间艺术化、媒介化、智慧化的发展现状与趋势。城市空间的拓展、数字化技术的革新将赋予灯光在夜间更强大的表现力和更多元的功能。

Focusing on four historical periods(early period,recent period,modern period and present period),the paper starts from multi-dimensional perspectives of light source technique,application scenario,night life,and urban space to sort out the role and function evolution process of lighting of different periods in city nighttime,and examines its evolution features.On this basis,it summarizes three turns of urban night lighting(e.g.space turning,public turning and function turning),and interprets the development status and trend of artistry,mediatization and intelligence of lighting in contemporary urban night.Overall,the expansion of urban space and innovation of digital technology will grant lighting with more powerful expressions and more diversified functions at night.
