摘　　要：为研究教室照明条件下学生瞳孔大小随亮度水平的变化规律,选择3位大学生作为被试者,采用iView X眼动仪,通过模拟教室照明条件的教室照明瞳孔大小测量系统实验,对3种教室常用色温(2 700K,4 000K,6 500K)荧光灯光源提供的5种背景亮度下的瞳孔面积变化值进行测量。结果显示,3种色温荧光灯下的瞳孔面积与背景亮度呈负指数函数关系;在教室照明条件下人眼瞳孔面积随背景亮度的变大而减小,并逐渐趋于稳定;在相同背景亮度下,色温越高的荧光灯照明时瞳孔面积越小。For the purpose of studying the rule of the pupil size vari changing under the classroom＇s lighting condition, the variation values 5 kinds background luminance affording by three kinds of fluores temperature （2 700 K, 4 000 K, 6 500 K）are measured, with iView X the measure system of pupil size under classroom lighting to simulate shows that, the relationship between pupil area and background lumina under 3 color temperature fluorescent illuminant;under the class smaller when the background luminance is higher, and is background luminance, the pupil area is smaller under the lighti latlo of 3 cent n while the luminance level is student＇s pupil area that under illuminant of different color eye tracking and the experiment of the classroom lighting. The result nce is negative exponential function room lighting condition getting stable graduall ng of higher color temp , the pupil area gets y; under the same erature fluorescent.
