摘要

分别采用模拟调光和PWM调光方式实现LED光调节。采用生理参数法

以在校大学生为研究对象

选择3种色温(3000

5600

6500 K)LED光源

在3种照度(300

500

800 lx)水平下

对8名(5男

3女)受测者在实验前后的脉搏和瞳孔进行测量。选择同样3种色温LED光源

分别采用两种调光方式添加蓝光(464 nm

20 lx)实现300 lx的照明环境

对12名(8男

4女)受测者在实验前后的脉搏和瞳孔进行测量。结果表明:两种调光方式实现的LED光环境对人体脉搏变化率和瞳孔收缩率的影响均没有显著性差异;在测试照明环境中添加蓝光

可引起人体脉搏变化率和瞳孔收缩率增大

峰值处分别增加约6%和9%。

Abstract

By using the physiological parameters method

the human non-visual effects were researched with the college students as objects. The LED dimming method included PWM and analog. The experiment condition included three levels of color temperature (3000

5600

6500 K) of white LED light source with three levels of illumination (300

500

800 lx). The pulse and pupil size of eight subjects (5 males and 3 females) were measured in black and white LED light with three levels of color temperature. Using the same three levels of color temperature white LED light sources and adding blue light (464 nm

20 lx) to achieve lighting environment of 300 lx

the pulse and pupil size of twelve subjects (8 males and 4 females) were tested. The results show that the impact of lighting environment created by two dimming methods on human pulse change rate and pupil contraction rate have no significantly different

and adding blue light in testing environment can cause the pulse change rate and pupil contraction rate to increase for about 6% and 9%

respectively.
