摘　　要：设计类教室对照明环境的要求不同于传统教室。但是,目前设计类教室还基本按照普通教室的光环境进行设计,同时存在学生对照度水平设计满意度低的问题。为提高设计类教室学生的学习效率和舒适度,确定设计类教室适宜的照度水平,本研究在重庆大学B区第二综合楼建筑学专业教室中安装LED灯具,并在不同照度水平条件下(125 lx、300 lx、500 lx、750 lx、1000 lx)进行视觉作业实验。每组实验过程中被试需完成一系列纸质作业量表,实验后被试填写主观舒适度评价量表,实验前后采集被试的血压、心率和体温三项生理指标,并全程记录被试的面部表情视频。通过分析不同照度水平条件下被试的主观舒适度评价、作业绩效、生理指数变化率和面部情绪,结果表明:750 lx照度水平下,被试的视觉作业准确率最高,500 lx照度水平下,完成视觉作业速度最快,综合绩效最高;750 lx照度水平下,实验前后被试的生理指数变化率最低,学习状态最轻松;1000 lx照度水平下,被试面部愉悦情绪值占比最高,750 lx照度水平下,面部厌恶情绪值占比最低;主观舒适度评价随着照度升高而增加,750 lx照度水平下,学习状态主观评价得分最高。因此,综合学习效率和舒适度,对于设计类教室而言,750 lx是较为适宜的照度水平。本文的研究能为设计类教室光环境的相关研究提供参考。Design classrooms have different requirements for lighting environments than traditional classrooms.Compared with traditional classrooms,students in design classrooms have more fixed seats,longer learning periods,and more diverse learning behavior patterns.This means that in design classrooms,where students are required to perform close,long-term,high-intensity visual assignment activities,the visual tasks are complex and heavily loaded,and they face a greater risk of visual fatigue.However,at present,design classrooms are still fundamentally designed based on the light environment of the average classroom,and students have low satisfaction with the design of illumination levels.This shows that the illumination level of 300 lx in ordinary classrooms cannot meet the visual requirements of students.Therefore,additional in-depth research is needed to determine the appropriate illumination level for design classrooms.To improve the learning efficiency and comfort in design classrooms,this study sets up LED lighting conditions with different illumination levels(125 lx,300 lx,500 lx,750 lx,1000 lx)in the architecture design classroom on the 17th floor of the second comprehensive building in B District of Chongqing University,and conductes visual work experiments under different illumination levels.The experiment uses the measurement of objective physiological index,subjective psychological sensation questionnaire,visual task test and facial expression video collection,analyze the change rate of physiological index,subjective comfort evaluation,job performance and facial emotion of subjects under different illumination levels,and discusses the relationship between different illumination levels,comfort level and learning efficiency of design classrooms.The subjective psychological sensation questionnaire consists of three parts:basic information,subjective comfort evaluation,and learning status evaluation.The evaluation of subjective comfort uses the five measures of brightness,fatigue,color rendering,relaxation,and plea
