Study On Outdoor Lighting Environment Design In Chang Chun Residential Area Under The Background Of Population Aging

Our country is at an accelerated stage of aging process.The population of the elderly are increasing.The construction of many residential communities ignores the needs of the elderly and does not give the elderly the level of attention that they deserved,resulting in a lighting environment in the residential community.The demand for outdoor activities at night for the elderly causes many elderly people to reduce the length of their outdoor activities and the number of outdoor activities at night.This paper mainly studies the lighting environment parameters of residential areas suitable for elderly people to perform outdoor activities at night and makes optimization design strategies.This article first investigated the status of night-light lighting environment in residential quarters in Changchun area.After consulting a large amount of relevant literature data,the questionnaire survey and on-site measurement methods were used to measure the nighttime illuminance values ? ? of residential communities and the elderly people lived in the residential communities.The research on the degree of satisfaction with the night lighting environment found that most of the districts in Changchun had low outdoor illuminance at night and basically did not take care of the outdoor activities of the elderly at night.The lighting environment could not meet the needs of the elderly for outdoor activities at night.,Then through analysis of survey data and combining domestic and foreign relevant standards,an average illuminancereference value of each region suitable for outdoor activities for seniors at night;Finally,on the basis of survey data,Dialux simulation method is applied to the elderly residential community outdoor night.The light environment is optimized for design,and the lamp fixture height,lamp arrangement density,etc.are optimized for simulation and analysis,and some optimization design strategies are derived to make the night outdoor lighting environment in the community more suitable for outdoor activities of the elderly.I hope to provide suggestions for the design of night outdoor lighting in residential communities.Provides a suitable physical environment for the elderly’s night-time activities and enriches their lives.
