摘要
本文研究了脉冲电流驱动下的LED白光对人体非视觉效应的影响。试验设置了6种频率、4种占空比共24组脉冲光及1组直流光作为对照组,研究了血压、心率、视觉辨识力等指标在不同光照条件下的变化。运用时间修正法得到更优的拟合线,对生理指标数据进行“五差值”修正分析。试验结果表明,不同占空比的脉冲光可以提升人眼视觉效能和视觉辨识力。得到脉冲光参数与心理指标之间的关系变化范围。除了100 Hz频率,其他高频段下的视觉舒适性均接近于直流光。
In this paper, the effects of LED white light driven by pulse current on human non-visual effects are studied. The experiment set up 24 groups of pulse light with 6 frequencies and 4 duty ratios and 1 group of direct current light as the control group to study the change of blood pressure, heart rate, visual perception and other indicators under different light conditions. The time correction method was used to obtain the best fitting line, and the five-difference correction analysis of physiological index data was carried out. The experimental results showed that pulse light with different duty cycles could improve the visual performance and visual perception of human eyes. The range of relation between pulse light parameters and psychological indicators was obtained. Except for 100 Hz frequency, the visual comfort in the other high frequency bands is close to direct current light.
