摘 要: 教室照明环境(背景照度、亮度对比、灯具布置、光源光色等)不仅对学生的用眼健康、视觉功效和学习效率等产生影响,还与节能息息相关。通过"教室照明瞳孔变化实验"研究显示,要达到相同视觉功效(即瞳孔面积相等)时,色温6 500 K荧光灯需要产生的亮度最少,耗电量最少,4 000 K荧光灯次之,2 700 K荧光灯耗电最多。即中、高色温荧光灯较低色温荧光灯的节能效果好。因此,从光源色温和视觉功效关系出发研究LED光源在教室的应用,既满足教学活动的视觉要求,又减少照明能耗。 The artificial lighting environment relate to background illuminance,luminance contrast,arrangement of lamps and illuminant color,etc. The classroom lighting not only produces influence on eyes health, visual performance and learning efficiency,but also has close relationship with energy saving. Through the experiment on pupil change in the classroom lighting,the paper shows that the fluorescent lighting of 6500K color temperature need to produce the least luminance and power consumption,the 4000K is the second and the 2700 K is the most. That means the high and medium color temperature fluorescent have better energy saving effect than the low color temperature fluorescent. Therefore,the research of LED light source used in the classroom should be based on the relationship between illuminant color and visual performance,in order to satisfy the visual requirement of study and reduce the energy consumption of lighting.
