Research On The Design Method Of The Light Environment In Musehms Based On Visual Adaptability

The musEhm is not only a collection of cultural relics sites,more for the education,publicity,communication task,and also rEvlects a country’s cultural soft power.With the growing cultural needs,the number of our musEhm increases.The musEhm space,light occupies a very important position,lighting and lighting reasonable design,can create a good space Evfect and feel.Among them,the Historical MusEhm of art because of its particularity,the exhibition space illumination are usually much lower than other public space,with the change of shading in different parts of space light environment,and the human visual system to adapt to changing light environment needs A certain period of time,and in every part of the space musEhm,extremely easy to cause visual discomfort.Lighting lighting design standards related to construction mainly based on static scene,to start the two dimensions of space and time based on the dark adaptation,not clearly dEvined.In the musEhm space more and more attention to the artistic Evfect and atmosphere of the times,this paper follow this by sources,visual adaptation based on the related theories,to people in the musEhm during the whole process of the vision of changing light environment as the research object,from the angle of dynamic light environment,the establishment of brightness time,illumination time and intensity distance.The illumination distance model,the existing MusEhm of light environment for the depth of the analysis,rEverence data measured by subjective evaluation experiment,so that the MusEhm of light environment design optimization strategy and principle.This paper is divided into four processes.Firstly,through the study of architectural lighting design and visual adaptation theory,the MusEhm of light environment and building and the form of technology in the development process of contact,and the related theory of visual perception were analyzed.Secondly,the MusEhm of the entire tour during the change of light environment as the research object,field research,eleven of the four domestic musEhm data measurement and questionnaire survey,through data analysis,summed up the main characteristics of China’s Contemporary MusEhm of light environment and the existing problems.Then,taking Tianjin MusEhm as the prototype,according to the survey data,five groups of buildings by simulation Outdoor exhibition hall(from the brightest to the dark environment)of the animated video,randomly invited 50 people participated in experimental evaluation of subjective satisfaction,that each part of the optical transition and the most suitable visual adaptation of brightness change.Finally,according to the on-the-spot investigation and the results of subjective evaluation,to the construction of graphic language in the abstract the musEhm lighting and building the optimization strategy and design suggestions.The research results can provide some guidance for the future of natural lighting and the lighting design of the musEhm building,provide a rEverence for similar large public buildings in the transitional space design and interior light environment design,and related to lighting and lighting design standard,The perfection of the standard provides the theoretical basis.standards.
