摘要
以2700K、4000K和6500KT5荧光灯为实验对象,两两配比,比较背景光源与视标光源在各种光色搭配条件下的视功效差异,寻找最佳光色搭配方案。为教室一般照明与黑板照明区域的光色配比提供实验参考,以达到保护学生视力、提高学习效率,创造节能、舒适的教室光环境的目的。
Visual acuity in a classroom is dependent on the difference between ambient lighting and light on the chalkboard.This experiment examines three types of fluorescent lamps with different colour temperatures,2700K,4000K and 6500K in which one type is for ambient and another for target lighting on the chalkboard.The results of the best combination of colour temperatures contrast for optimal lighting condition to reduce eye strain,enhance learning and achieve energy efficient in a classroom lighting environment.
