人类眼睛上的日常明暗模式在维持健康的昼夜节律方面起着重要作用。室内空间白天光线不足可能会对居住者的健康和福祉产生长期负面影响。因此，在某些建筑环境中应用昼夜节律照明是有吸引力的。在这项工作中，我们介绍了创新的昼夜节律照明设计方法，并通过将这些方法与传统的照明设计方法进行比较，研究提高功效的潜力。对于空间方面，我们表明，与将初始通量分布到高反射房间表面的方法相比，专注于水平工作平面照度的常规照明设计方法可能导致间接角膜照度的非常低效的传递;对于光谱方面，结果表明，追求高发光效率的传统方法可能导致最坏的结果，基于四组分颜色混合分析的昼夜节律功效的案例情景。昼夜节律系统的两个主要光谱灵敏度模型（即，CLA模型和EML模型）进行了比较，每种模型都导致光谱昼夜节律功效相对于色温的不同趋势，但光谱优化的策略相同。基于空间和光谱方面的分析，提出了一个有效的昼夜节律照明解决方案的框架，以指导新的良好的照明设计与健康效益。结果表明，所提出的新方法可以潜在地将整体昼夜节律照明效率提高高达3.6倍。
Daily light-dark patterns incident on human eyes play an important role in maintaining a healthy circadian rhythm. The lack of daytime light in indoor spaces could negatively impact the occupants’ health and well-being in the long term. Therefore, applying circadian lighting in certain built environments is attractive..In this work, we introduce innovative methods for circadian lighting design and investigate the potential of efficacy improvement by comparing these methods with traditional lighting design approaches. For the spatial aspect, we show that the regular lighting design approach focusing on horizontal workplane illuminance could lead to a very inefficient delivery of indirect corneal illuminance compared with the proposed method of distributing.initial flux to a highly reflective room surface; for the spectral aspect, it is shown that the traditional approach of pursuing high luminous efficacy could potentially lead to the worst-case scenario for circadian efficacy based on a four-component color-mixing analysis. Two leading spectral sensitivity models for the circadian system (i.e., the CLA model and the EML model) are compared, each of which leads to different trends of spectral circadian efficacy versus color temperature but the same strategy for spectral optimization. Based on the analysis in both the spatial and spectral aspects, a framework of efficient circadian lighting solutions is proposed to guide new good lighting design with health benefits. It is shown that the proposed new approaches can potentially improve the overall circadian lighting efficacy by up to 3.6 times.
