摘　　要：地下轨道交通在城市交通中占有重要地位。目前,我国地铁车站主要采用人工照明。通过部分实测与研究,站内部分场所照度及出入口亮度比值未达标准。相关标准规范也仅仅是从满足基本视觉功能方面做了规定,未考虑全国不同光气候区地面地下光照参数对工作人员及乘客生物节律与视觉相关性等的影响。通过测量,分析了晴天、阴天天然光照度、色温;分析了不同光气候区天然光变化的规律;测量了地铁常用的荧光灯与LED灯光谱功率分布,比对天然光光谱,得出LED光谱连续性优于荧光灯光谱的结论;分析了色温中蓝光成分的高低对人的褪黑素含量的影响及其与人的困意与警觉性的关系。提出了根据不同光气候区天然光的特征,运用智慧照明控制方法,在满足视觉功能的基础上,使地下光环境符合人的生物节律,为地铁照明研究提供了一种新方法。Underground rail transit plays an important role in urban transportation. At present, Chinese subway stations mainly use artificial lighting. Through some measurements and researches, the illumination of some sites in subway stations and the ratio of luminance of the entrance were not met. The relevant standard is also only from satisfying the basic visual function aspects to stipulate, the effects of ground and underground illumination parameters in the different light climate zones on the biothythm and visual correlation of workers and passengers were not considered. It analyzes the natural light variation law of different light climate zones by measuring and analyzing the natural light intensity and color temperature in sunny days and cloudy days. It measures the spectrum power distribution of fluorescent lamp and LED lamp used in subway, then it compares with the natural light spectrum, and it’s found that the LED is better than the fuorescence on spectral continuity. The relationship between the blue light in color temperature and the effect of melatonin on people＇s drowsiness and alertness was also analyzed. This paper proposes that it can employ the intelligent lighting controlling method according to the characteristics of the different climate zones of natural light to make the underground light environment satisfy the human biological rhythm on the basis of satisfying visual function. It’s expected that it will provide a new method for the subway lighting research.
