研究了不同色温LED照明时节律效应随年龄的变化规律。在节律因子计算公式中
引入不同年龄人眼的透射谱
分析LED色温和年龄对节律因子的影响。然后
测量了12名老年和18名青年男性在黑暗状态下以及照度为500 lx、不同色温LED照明时的心率
采用黑暗状态与照明状态的心率变化表征节律效应
来验证所得的理论规律。结果表明:色温为6 500
5 500
4 500
3 500 K的LED照明时
青年人(20岁)的节律因子分别为1.1
0.7
0.5
0.44
不同色温LED照明时心率变化率差异明显;老年人(65岁)的节律因子分别为0.5
0.3
0.25
0.2
不同色温下心率变化较小。在同一色温LED照明时
节律效应随着年龄的增加而减小。LED色温不同时
青年人节律因子的变化较大
老年人则变化较小。
The change rule of circadian effects with ages in LED lighting of different color temperatures was studied. The ocular transmittances of different ages were introduced into the calculation formula of circadian action factor
and then the changes with ages and LED temperatures color were obtained. The heart rates of 12 old and 18 young male participates were measured in black and LED lighting of different color temperatures and the illuminance of 500 lx. The difference of heart rate between black and lighting was proposed to determine the circadian effect in order to verify the calculated results. Under the LED lighting conditions with the color temperatures of 6 500
5 500
4 500
3 500 K
the circadian action factors of the young are 1.1
0.7
0.6
0.44
respectively
and the heart rate changes differ significantly among different color temperature LED lighting. The circadian action factors of the old are 0.5
0.3
0.25
0.2
respectively
and the heart rate change little among color temperatures. The circadian action factor of the same color temperature LED lighting decreases as the age increases. The circadian action factor of the young varies across different color temperatures LED lighting
therefore
the old changes little.
