【摘要】：研究人在不同环境温度下,光源照度和色温对人体体核温度、皮肤平均温度和皮肤血流量的影响,探索光源照明对人体体温调节的作用.对8名受试者在人工气候室不同环境温度(18,30°C)、光源照度(300,1 000lx)和色温(3 000,6 000K)下的体核温度、平均皮肤温度和皮肤血流量进行了60min的测量和记录.结果表明:无论在高温还是低温条件下,当人体暴露于低色温光源下时人的体核温度较高色温光源下时高;在较低的环境温度下,平均皮肤温度和皮肤血流量在冷色温光源下的值高于低色温光源下的值;在较高温度下,平均皮肤血流量和皮肤温度在低色温光源下的值高于冷色温光源下的值.因此,在环境温度发生变化时,光源照明对人体的热调节起着一定的作用,在环境高温下以运用高色温光源为宜,反之亦然.这提示人们在不同的环境温度下对于光源照度和色温的选择是一个值得重视的问题,除视觉需要外,选择时还应考虑人体生理功能的平衡和舒适感.
[Abstract]:The effects of light source illumination and color temperature on body nucleus temperature, skin mean temperature and skin blood flow were studied in different ambient temperatures, and the effects of light source illumination on human body temperature regulation were explored. The body nucleus temperature, mean skin temperature and skin blood flow were measured and recorded by 60min in 8 subjects at different ambient temperatures (18 掳30 掳C), illuminance (300 000lx) and color temperature (3 000 ~ 6 000 K) in the artificial climate room. The results show that the nucleation temperature of human body is higher when the human body is exposed to low color temperature light source under the condition of high temperature or low temperature than that under high color temperature light source. At low ambient temperature, the average skin temperature and skin blood flow were higher under the cold color temperature light source than in the low color temperature light source. At higher temperature, the average skin blood flow and skin temperature in low color temperature light source are higher than those in cold color temperature light source. Therefore, when the ambient temperature changes, the illumination of the light source plays a certain role in the thermal regulation of human body, and it is appropriate to use the high color temperature light source in the high temperature environment, and vice versa. This suggests that the choice of illuminance and color temperature under different ambient temperatures is a problem worthy of attention. In addition to the visual needs, the balance and comfort of human physiological functions should be taken into account in the selection.
