Analysis And Optimum Design Of Nocturnal Lighting Environment For Huaqiang North Commercial Pedestrian Street

With the continuous development of urban economy,night life has become an indispensable part of modern urban life,which is based on the development of night light environment.Commercial pedestrian street is an important carrier of urban night life.Whether the quality of its night light environment can be guaranteed is very important for urban residents.However,the original commercial pedestrian street lighting more considers the function of city lighting and less considers the needs of users,which is in contradiction with the growing material and cultural needs of people.In order to improve the quality of night light environment of commercial pedestrian street,Huaqiangbei Commercial Street in Shenzhen was selected as the research object.The theory and method of environmental behavior were applied to investigate and analyze the night light environment of commercial pedestrian street from the user's point of view,and the optimal design strategy was put forward.In this paper,the related literature at home and abroad is studied by means of literature survey.The basic concepts and definitions of environmental behavior,commercial pedestrian street and night light environment are sorted out.The design theory of night light environment of urban commercial street is studied,the specificity of night light environment of commercial pedestrian street is discussed,and its basic requirements are summarized.Based on the theory of environmental behavior,the behavior and psychological needs of the users of commercial pedestrian street space are analyzed in depth,and the correlation between unnecessary activities and the quality of light environment is established by applying the theory of Yang Gail's outdoor space activities.On this basis,the demand of the users of commercial pedestrian street is divided into four levels,i.e.safety,combined with Maslow's hierarchy of needs theory.Sexual needs,comfort needs,aesthetic needs and interesting needs.Through activity annotation and semantics analysis,this paper explores the present situation and existing problems of night light environment in Huaqiang North Commercial Pedestrian Street,compares and analyses the evaluation index of night light environment quality of Huaqiang North Commercial Pedestrian Street with the behavior mode and light environment parameters of the active crowd,extracts the main factors affecting night light environment quality of urban commercial street,and puts forward the night light environment quality ofcommercial Pedestrian Street.Design strategies for optimizing the light environment.Based on the subjective evaluation results of the semantic analysis method,the problems existing in the survey samples are found out,and the corresponding optimization design scheme is put forward.In this paper,the night light environment of Huaqiangbei Commercial Pedestrian Street in Shenzhen is systematically studied.Based on the user's behavior and demand,the optimal design strategy is put forward,with a view to providing some reference for the future design of night light environment of commercial street.
