高校图书馆阅览室混合阅读健康光环境评价研究

Research on the Evaluation of Mixed Reading Health Lighting Environment in University Reading Rooms

高校图书馆阅览照明环境的质量对于学生的视觉感知、情绪评价、认知效率非常重要,考虑天然光变化的照明环境设计是阅览室提升光环境质量、满足健康照明要求的重要发展方向。本文以天然光环境下的人工照明对健康阅读的影响为研究目的,搭建了阅读照明环境实验室,采用主观评价、任务绩效和生理指标测量相结合的研究方法,在17:30—20:30,以0.5 h为划分的6个时段内,针对人工光环境对视觉感知、情绪感知、认知评价等3方面的影响进行主客观评价,最后用熵权法确定相关指标的权重。实验结果表明:以单一评价指标为标准,在17:30—20:30时段内,最佳人工光照度呈上升态势。对比不同评价指标,其相同时段内,最佳人工光照度存在差异。且视觉不适、主观警觉度、视觉清晰度分别在17:30—19:00、19:00—19:30、19:30—20:30时段内应为照明设计的重点考虑内容。研究结果旨在为图书馆阅览室的照明设计与优化提供依据。

The quality of lighting in university library reading rooms is crucial for students’visual perception,emotional evaluation and cognitive efficiency.The design of lighting environment considering natural light changes is an important development direction for improving the quality of lighting in reading rooms and meeting health lighting requirements.The purpose of this study is to investigate the impact of artificial lighting on healthy reading under natural light environments.An experimental laboratory for reading lighting environments was set up,and a research method combining subjective evaluation,task performance and physiological indicator measurements was adopted.From 17:30 to 20:30,divided into six periods of 0.5 hours each,the study focused on subjective and objective evaluation of the effects of artificial lighting environments on visual perception,emotional perception,cognitive assessment.Finally,the entropy weight method was used to determine the weights of relevant indicators.The experimental results indicate that,based on a single evaluation criterion,the optimal artificial illuminance shows an upward trend from 17:30 to 20:30.When comparing different evaluation criteria within the same time period,variations in the optimal artificial illuminance are observed.Additionally,visual discomfort,subjective alertness and visual clarity should be the key considerations for lighting design during the periods of 17:30 to 19:00,19:00 to 19:30,and 19:30 to 20:30,respectively.The aim of this research is to provide a basis for the lighting design and optimization of library reading rooms.
