The Study On The Design Of The Luminous Environment Of The Underground Walking Street

With the rapid development of urbanization and the improvement of people's living standard,the general concept of city design change into vertical development under the ground space from the plane development on the ground surrounding one city center.As a result,the pedestrian street is developed.People begin to pay more attention to its quality than its quantity.The 3D space,therefore,is improved and it is also a new way for city planning.With different environment and form,the underground space design pays more attention to the light environment design.This article study on two factors: physical matters affecting the light environment design and people's comfort.By questionnaire survey and measurement,we put forward methods to improvement the light environment design of pedestrian street and already carried them out.The high cost in the preliminary phase makes the underground construction study limits on structure design,theory in supporting and construction technology etc..Some defects still exist in lighting design:(1)Only pay attention to the entity component design.Only care about the brightness not the lighting design.Design the underground space as the extension of the overground space.(2)Only care about the physical index of the light environment and ignore its psychological effect and the contact between the space and human behavior,physiology,psychology.(3)Some unprofessional designer lack knowledge of light calculation and photophysical techniques so they design not strictly according to the national light standard.Therefore,light is abundant and floodlight space is made.The problems exposed in the questionnaire survey and measurement make it more urgent to improve the light environment of the underground pedestrian street.Put forward proper lighting design method,make theory analysis and design test on the problems as well as learn from excellent research results at home and abroad.Propose a series of optimization design measures for the light environment in the public space in the underground pedestrian street and take some measures on the relation between green light and commercial environment so as to improve the light environment in underground pedestrian street and the mass experience.
