摘要
在真实教室照明环境中,通过不同色温(6 500 K高色温、4 000 K中间色温、2 700 K低色温)荧光灯照明下,学生完成视觉作业的效率和生理指数变化的比较实验,从人的主观心理感受、血压脉搏等生理效能和视知觉作业绩效三方面,对教室照明中光生物效应与视觉功效的关系进行分析。研究指出教室照明中适宜的光源光色对提高学生视觉功效和学习效率具有重要的现实意义。
In the real classroom lighting environment, under the fluorescent lighting of three kinds of color temperature （6 500 K high color temperature, 4 000 K medium color temperature, 2 700 K low color temper- ature） , by the ＂comparative experiments of visual task performances under different illuminant color＂, this paper studies on the relationship between the biological effect and visual performance in classroom lighting from three aspects of the subjective psychological feeling, physical efficiency such as blood pressure, and vis- ual perception performance. The study shows that, under the high and medium color temperature of fluores- cent lighting, the error rate of visual work is low, the proofreading speed and the mental work ability index is high, and the learning is the most efficient. The average variation rate of physiological index such as blood pressure, pulse is the lowest under the fluorescent lighting of medium color temperature, and the learning is relaxed and easy. Also among the students, the subjective psychological preference rate is the highest of the medium color temperature. This shows that, to improve students＇ visual performance and learning efficiency, the use of medium color temperature fluorescent lighting in classroom is of great practical significance.
