[Abstract]:Based on the National Natural Science Foundation of China "Research on Photobiological Safety of classroom Light Environment" (Grant No. 51178483), this paper studies the advantages of dynamic light environment on the basis of the established artificial light synthesis model. The range of color temperature and light intensity of LED light source was extended by the subjects' independent dimming, and the factors affecting the color temperature and intensity of the preferred light source were studied. As a basic research to establish reasonable dynamic light environment and perfect artificial light synthesis model. Based on a large number of domestic and foreign research, this paper introduces the research trends of classroom light environment, photobiological effect, dynamic light environment and health lighting. The advantages and disadvantages of classroom lighting and various indexes of classroom lighting requirements are analyzed. Finally, the main problems and research directions of this paper are determined, that is, through subjective preference light environment dimming way, the human body preference light environment data are sampled, and then the light environment data are evaluated. This thesis is divided into two parts: the first part is the contrast experiment of students' learning performance under LED fixed light environment and dynamic light environment, the second part is the light dimming experiment of multi-sample subjective preference light environment under LED light source. The third part is the subjective preference light environment dimming experiment under the LED light source, and collects the data such as mood scale, attention evaluation scale, physiological index, etc. Finally, based on the subjective preference light environment data analysis results and the scale, The research results of index evaluation provide reasonable suggestions for the study of dynamic light environment in college classrooms and the study of artificial light mixing model. Comparison of learning performance between fixed light environment and dynamic light environment part: under the light source of: led, the students' strength, brainpower and performance index after learning in fixed and dynamic light environment were compared to verify the advantages of dynamic light environment. Autonomous dimming experiment part of the light-environment data of students' subjective preference was collected under the light source of: led. The factors influencing students' preference for color temperature and preference for illumination were studied. Explore the screening method of color temperature and illuminance. The evaluation part of the scale: through the evaluation of various scales, the students' subjective preference of light environment was evaluated, and the influence of emotion, sleepy and physiological index on the preference light environment was observed. Through the above experimental research, the whole experiment process is reviewed and summarized in the last part of the thesis, and the students' preference for light environment and outdoor natural light environment, experimental lamp limitation, physiological rhythm, gender difference and emotion are analyzed synthetically. The importance of establishing dynamic light environment is demonstrated, and some reasonable suggestions are put forward for improving the synthetic model of artificial light and the establishment of dynamic light environment mixed with sky light and artificial light.
