The quality of the indoor lighting environment in the reading space of the university library is essential for students' visual perception, emotional evaluation, and cognitive efficiency. The design of the lighting environment considering the change of natural light is one of the important development directions to improve the light environment quality of the reading room and meet the health requirements of students. This paper from the perspective of reading vision, emotion, and cognitive probes into the natural light environment lighting design, builds a reading lighting environment laboratory, using subjective evaluation, task performance, and physiological indicators of the measurement method, first analyses the weight of different indicators under different time, establish lighting environment comprehensive evaluation index I and artificial illumination and desktop illumination prediction model.
