Research On The Lighting Optimization Design Of Architectural Classroom

This paper relies on Chongqing University Innovation Team Building Project(Team Name: Health Lighting Innovation Team,No.CXTDX201601005).According to a research report,the myopia of college students in China has reached 90%,and this data is increasing.Due to the diversity and long duration of learning behavior patterns,architectural students are faced with more serious visual fatigue risks than other majors.A large number of studies have confirmed that the improved classroom lighting environment can effectively alleviate the students’ visual fatigue and prevent myopia.It can be seen that as an important learning place for students majoring in architecture,the lighting optimization design of architectural classroom is of great significance to alleviate the students’ visual fatigue and prevent myopia.Students’ learning behavior patterns are diverse,and their vision is no longer limited to the horizontal desktop,which means that the lighting design based on the illumination and uniformity of the horizontal working face can no longer meet the different needs of various behaviors for lighting.On the other hand,the variety of behavior patterns has brought about the freedom and change of the flat layout,which not only challenges the lighting design of architectural classrooms,but also provides an integrated design idea for the lighting environment by combining flat layout and lighting technology.Therefore,for different behavior patterns,how to design the lighting environment as a whole is the research problem proposed in this article.This article takes the optimization design of architectural classroom lighting as the research object,and analyzes the lighting needs of different behavior patterns from the perspective of students through questionnaires,field measurements,analytic hierarchy process(AHP),simulation optimization and other methods to guide lighting technology and flat layout design.And establish an integrated lighting environment design with different behavior patterns in a typical space.On this basis,the lighting technology and the layout design strategy corresponding to different behavior patterns are explored,which provides a substantial reference for the optimization design of architectural classroom lighting.This article conducts research from the following aspects:Theoretical research: theoretical research on architectural classrooms,lighting design indices,and lighting design methods.It summarizes the behavioral characteristics of students,the space form and layout characteristics of architectural classrooms,studies the requirements for lighting indices of architectural classrooms,analysis of classroom lighting design methods at home and abroad,and discusses multi-objective optimization methods that are suitable for the optimal design of architectural classroom lighting.Investigation and research: Investigate the status of architectural classrooms through questionnaires,measurements,and observations.The survey is divided into three parts.The first part investigates student behaviors and summarizes the main behaviors and behavior distribution;The second part conducts a rating survey on the importance of lighting indices for various behaviors,and summarizes important lighting indices for different behaviors;The third part investigates the current status of lighting,and summarizes the characteristics of lighting needs for different behaviors and existing problems in lighting design.Through these three parts of investigation,we know the relationship between space,behavior,and lighting,as the starting point for subsequent research.Simulation analysis: screening of typical spaces,behaviors,and lighting indices.Use DIALux evo to analyze the factors that affect lighting,including factors related to lighting technology and layout.AHP is used to calculate the weight of the lighting indices of each behavior,so as to determine the relationship between the behavior and the lighting influencing factors.Optimization design: Orthogonal experimental design method combined with DIALux evo was used to simulate multiple sets of multi-factor schemes,comprehensive analysis of lighting influencing factors,so as to determine the lighting technology and the layout optimization plan for each lighting indices.According to the single-indices optimization scheme and the comprehensive evaluation function,a multi-indices comprehensive optimization scheme with different behavior patterns is constructed.Solve the problem: Determine the design principles of architectural classroom lighting according to the characteristics of space,behavior,and lighting relationships.According to the research results,the overall design strategy of the lighting environment combined with the behavior mode is proposed,that is,each behavior mode corresponds to a different combination of lighting technology and plan layout.And put forward the corresponding lighting technology and plan layout design strategy,summarize the reference design diagram of the integrated design of the architectural classroom lighting.Finally,the author summarizes the research results of this article,analyze the shortcomings of research and look forward to related research.The research results of this article can solve the problems of architectural classroom lighting,and help to promote the subdivision of classroom lighting research,and at the same time provide reference data,strategies and research methods for the lighting design of other places with diverse behavior patterns.
