政策制定者和标准化机构已经开始就夜间使用照明产品提出建议，目的是减少对人类健康的负面影响。我们报告了一系列实地测量，以量化不同的人类光感受器的反应和可能的抑制褪黑激素的生产所造成的大都市的外部照明。总共在5.6英尺处进行了888次光谱和888次照度测量。在六个商业区的地面上，其中三个在香港，三个在上海。结果发现，在上海和香港的47%和86%的测量光刺激可能会引入抑制褪黑激素的产生，其特征在于使用昼夜节律刺激（CS），因为他们有CS值超过0.05，急性褪黑激素抑制的工作阈值。此外，现场测量和计算机模拟都表明，具有较高相关色温（CCT）的光刺激可能不一定比具有较低CCT值的光刺激引起更强的褪黑激素抑制。
Policymakers and standardization bodies have started to make recommendations about the use of lighting products at night, with the goal of reducing negative impacts on human health. We report a series of field measurements to quantify the responses of different human photoreceptors and the possible suppression of melatonin production caused by the exterior lighting in metropolises. In total, 888 spectral and 888 illuminance measurements were taken at 5.6 ft. above the ground in six commercial business districts, with three in Hong Kong and three in Shanghai. It was found that 47% and 86% of the measured light stimuli in Shanghai and Hong Kong may introduce suppression of melatonin production, as characterized using circadian stimulus (CS), because they had CS values beyond 0.05, a working threshold for acute melatonin suppression. In addition, both field measurements and computer simulations suggested that light stimuli with higher correlated color temperature (CCT) may not necessarily cause stronger melatonin suppression than those with lower CCT values.
