摘要(Abstract):

以24 h为周期的自然日光可有效调节人体内部生物钟,使其与地球自转周期同步。然而,不恰当的人工照明以及现代社会的工作、生活方式使得这种由自然日光主导的人体节律调节机制变得脆弱,甚至可扰乱昼夜节律并造成长期的健康危害。因此,在室内空间应用节律健康照明具有重要价值。本文总结我们的近期工作,提出针对节律健康照明的光谱和照明设计优化:从光谱角度,论证了基于节律效应的光谱优化可显著降低节律照明能耗;从照明设计角度,论证了相较于传统照明设计,侧重于室内表面反射率和灯具初始光通量投射方向的照明设计可极大提高间接光眼部照度。本文提出综合的理论框架以优化光谱和照明设计参数,从而实现高效率的室内节律健康照明。
The 24-hour light-dark cycle enabled by daylight can effectively synchronize the internal clock of human body to the period of earth's self-rotation. However, inappropriate artificial lighting and the work and lifestyle of modern society tend to disrupt the circadian rhythm and may cause long-term health risks. Therefore, applying circadian lighting in certain built environments is very important. This paper summarizes our recent works on the optimizations of lighting spectra and illumination-design to achieve efficient circadian lighting: for the spectral aspect, it is shown that spectral efficacy for circadian impact can be improved by a considerable amount when switching from the traditional high-luminous-efficacy strategy to the high-circadian-efficacy strategy; for the illumination-design aspect, it is demonstrated that compared to the traditional method of lighting design that focuses on visual task performance, our proposed approach focusing on room-surface reflectance and the direction of initial luminaire flux can significantly improve indirect corneal illuminance. Combining both aspects, a framework is proposed to achieve healthy and efficient circadian lighting.
