Research On Nightscape Lighting Design Of Open Space In Main Urban Area Of Handan City From The Humanistic Perspective

Urban open space is the display of the city image.It is the main activity place for people to walk,communicate,watch,and travel.With the accelerated urbanization process in China,urban nightscape lighting design is gradually attracting attention,and urban nightscape lighting has also changed from the original function-oriented to a new stage of human-oriented,paying more and more attention to the needs of usersThis article takes the open space in the main urban area of Handan City as the research object,takes the needs of the crowd for nightscape lighting as the guide,and conducts research on the design of open space nightscape lighting.First of all,through the literature research method to analyze the background of the lack of urban image at night,the use of bibliometric methods to summarize the corresponding research results,urban lighting theory,the theory of hierarchy of needs,behavioral psychology theory,etc.as theoretical support,to build a theoretical system of urban open space nightscape lighting design;Second,typical PSPL research method was applied to field investigation in the open space in the urban area,aided by SPSS statistical analysis and the SD method to draw a crowd subjective evaluation and the correlation the influence factors of nightscape lighting quality as a result.Through field survey,this article analyzes of different problems of open space existing in the night scene illumination design and people’s subjective visual factors.Under the hierarchy theory of needs,the activities of people demand for urban open space illumination can be divided into three levels,including security requirements,ornamental requirements and sense of place requirements;Then,based on the needs of the crowd for nightscape lighting,the index system of nightscape lighting in urban open space is constructed from the perspective of human,and the index system is weighted by the entropy value method,and the evaluation results are obtained.Finally,from three aspects of safety,appreciation and sense of place,this paper puts forward optimization measures for nightscape lighting design of urban open space from the human-oriented perspective,and carries out targeted optimization design for nightscape lighting of open space in the main urban area of Handan City.This article presents a systematic study of night lighting in open spaces in the main urban area of Handan city,constructs a humanistic perspective of nightscape lighting index system for open spaces in the main urban area of Handan city from the demand of people,and proposes nightscape lighting optimization design measures,in order to provide qualitative and quantitative analysis reference for urban open space night lighting and create a high-quality night lighting design with "human-light-environment".The aim is to provide qualitative and quantitative analysis reference for urban open space night lighting,and to create a high-quality night lighting design with harmonious development of "human-light-environment".
