Abstract：
Background: Human circadian clocks are synchronized daily with the external light-dark cycle and entrained to the 24-hour day. There is increasing evidence that a lack of synchronization and circadian entrainment can lead to adverse health effects. Beyond vision, light plays a critical role in modulating many so-called non-visual functions, including sleep-wake cycles, alertness, mood and endocrine functions. To assess (and potentially optimize) the impact of light on non-visual functions, it is necessary to know the exact \'dose\' (i.e. spectral irradiance and exposure duration at eye level) of 24-hour light exposures, but also to include metadata about the lighting environment, individual needs and resources.
Problem statement: To address this problem, a new assessment tool is needed that uses existing metrics to provide metadata and information about light quality and quantity from all sources. In this commentary, we discuss the need to develop an evidence-based integrative lighting score that is tailored to specific audiences and lighting environments. We will summarize the most compelling evidence from the literature and outline a future plan for developing such a lighting score using internationally accepted metrics, stakeholder and user feedback.
Conclusion: We propose a weighting system that combines light qualities with physiological and behavioral effects, and the use of mathematical modelling for an output score. Such a scoring system will facilitate a holistic assessment of a lighting environment, integrating all available light sources.

摘要：
背景：人类生物钟每天与外部明暗周期同步，并夹带到24小时的一天。越来越多的证据表明，缺乏同步和昼夜节律夹带会导致不良的健康影响。超越视觉，光在调节许多所谓的非视觉功能中起着关键作用，包括睡眠-觉醒周期，机敏,情绪和内分泌功能。为了评估（并可能优化）光线对非视觉功能的影响，有必要知道24小时光照的确切剂量（即眼睛水平的光谱辐照度和曝光持续时间），还包括有关照明环境的元数据，个人需求和资源。
问题陈述：要解决此问题，需要一种新的评估工具，该工具使用现有的指标来提供有关所有来源的光质量和数量的元数据和信息。在这篇评论中,我们讨论了需要制定一个基于证据的综合照明得分，是为特定的观众和照明环境。我们将总结文献中最令人信服的证据，并概述使用国际公认的指标开发此类照明评分的未来计划，利益相关者和用户反馈。
结论：我们提出了一种将光质与生理和行为效应相结合的加权系统，以及使用数学建模来获得输出分数。这样的评分系统将有助于对照明环境进行全面评估，集成所有可用的光源。
为了评估光线对非视觉功能的影响，必须知道24小时曝光的确切“剂量”以及有关照明环境和个人的元数据。迄今为止,还没有可用的测量方法允许针对人类的视觉和非视觉方面对照明环境进行整体评估。我们讨论了基于证据的综合照明评分的必要性，并概述了其开发计划。基于证据的综合照明评分，其中包括一个加权系统，将光质与生理和行为效应相结合，只有通过联合力量才有可能，知识,和许多学科的方法论。这样的分数需要可持续评估的潜力，改善和维护优化的照明环境，长期促进任何群体的健康和生产力。
