摘　　要：大学教室因时间利用率高、场景多变和LED普及的特点,其光环境质量的改善有助于提高大学生对环境的满意程度,进而提升学习效率。本文以北京市某大学多栋教育建筑的典型教室光环境为对象,结合客观测量和主观问卷调研,提出并利用一套完整的分析流程,旨在识别日夜不同时段提升学生光环境满意度的归因客观指标及其阈值。结果显示,LED光源基本满足现有标准在照度和均匀度方面的要求;日间和夜间的上课与自习场景下所需要控制的指标及其阈值均有不同,主要包括色温、显色性、亮度对比度、垂直照度和生理等效照度等。本研究为大学教室光环境视觉舒适性营造提供了基础数据,对其光环境的质量提升具有指导意义。Due to the characteristics of high time utilization rate,changeable scene and the popularity of LED,the improvement of luminous environment quality in university classrooms is conducive to improving the environmental satisfaction of college students,thus improving their learning efficiency.This paper takes the typical classroom luminous environment of several educational buildings in a university in Beijing as the object,combining objective measurement and subjective questionnaire survey,and using a set of the scientific analysis process,aiming to identify the objective index and the threshold value of improving students’satisfaction with theluminous environment at different times of day and night.The results show that LED basically meet the requirements of existing standards in terms of illuminance and uniformity.The indexes and thresholds that need to be controlled are different in different scenes of class and self-study in day and night,such as color temperature,color rendering,luminance contrast,and physiological equivalent illumination.This study provides basic data for the comfort requirements of the luminous environment in university classrooms,which has certain guiding significance for the quality improvement and construction of the luminous environment.
