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