| With the significant improvement of social economy in China,people are yearning for a healthy living environment.The demand for lighting in residential areas is no longer satisfied with the most basic visual use conditions.The role of the lighting environment on the sense of belonging and security of residents is increasingly valued,and it has gradually become one of the content of residents’ judgments on the quality of residential areas.At present,there are relatively few studies on the impact of lighting in residential areas on pedestrians’ psychological feelings,which is not conducive to the healthy development of environmental design in residential areas.Through research and experiments,this paper explores the various influencing factors in the night light environment of the residential area,and obtains the impact of each factor on the residents’ psychological security feelings.First of all,on the basis of a large amount of literature research,this paper takes Tianjin as an example,selects 6 representative new and old communities,and uses field survey methods to obtain the illumination distribution in the lighting environment of old and new residential areas,Color temperature,brightness,semi-cylindrical illuminance and questionnaire data,analyze and study the influencing factors of the lighting environment in the residential area,and obtain the current status of the night light environment in different residential areas and the subjective feelings of pedestrians in the residential area.And analyze the crux of the problem of the night light environment in the residential area and its related indicators.Secondly,by setting up an experimental environment on site,the maximum illuminance and color temperature on the ground are used as independent variables to compare the distribution characteristics of illuminance in different residential areas;the questionnaire data of the test population are obtained,and the maximum illuminance and color temperature on the ground and pedestrian safety are summarized The relationship between.Thirdly,use eye trackers to conduct experimental tests in virtual scenes and introduce more environmental conditions into the model to test pedestrian safety feelings under changes in color temperature,ground maximum illumination,light source distance and environmental complexity;obtain the subject’s Subjective feeling data,through mathematical statistical analysis to determine the relationship between different influencing factors and a sense of security.In this way,the ways in which the color temperature,the maximum illuminance on the ground,the distance of the light source,and the environmental complexity affect pedestrian safety are obtained,and the optimal value range is summarized.Establish a mathematical model between influencing factors and sense of security through multiple regression analysis in order to obtain its optimal value more accurately.In this paper,the pedestrian safety perception of the night light environment in the residential area is studied in questionnaire survey,field test experiment and laboratory virtual scene eye movement experiment.the characteristics of the physiological and psychological changes of people under different factors are analyzed,and the lighting environment in the residential area A quantitative relationship between various factors and a sense of security.The research results obtained can provide data support and theoretical basis for the future design of lighting spaces in residential areas,and provide references for the improvement of existing national standards. |
