Abstract

Most people today stay in a constant artificial lighting environment for a long time. Lack of sufficient daylight exposure may lead to circadian, sleep or mental problem. Dynamic lighting is an effective countermeasure in consideration of its dynamicity. However, besides its changeability, whether the daylight simultaneousness of dynamic lighting has a beneficial effect is unclear. A lab-based study was carried out to explore the effect of Daylight-Simulcasted Dynamic Lighting (DSDL), which simulates the simultaneous information of daylight conveyed by its variation. A reversed pattern of DSDL (Re-DSDL) was also introduced as one of the test conditions for comparison. The within-subject experiment was performed by 24 participants in four conditions: two dynamic lighting patterns (DSDL and Re-DSDL) in two periods (dawn and dusk). The dependent variables were psychological states, physiological indicators and cognitive performance. The results showed that DSDL brought greater benefit to the psychological state than Re-DSDL in general. During dawn, participants experienced less anger and depression in DSDL than in Re-DSDL; during dusk, participants experienced less anger and vigour in DSDL than in Re-DSDL. DSDL also had a significant effect on some of the physical indicators compared with Re-DSDL, but no effect on cognitive performance.

日光模拟动态照明的好处:一项将同时性与动态性分离的实验

今天大多数人长时间呆在恒定的人工照明环境中。缺乏充足的日光照射可能会导致昼夜节律、睡眠或精神问题。考虑到其动态性，动态照明是一种有效的对策。然而，除了其可变性外，动态照明的日光同时性是否有有益的影响尚不清楚。一项基于实验室的研究探讨了日光模拟动态照明(DSDL)的效果，该技术模拟了日光变化所传递的同步信息。本文还介绍了一种反向DSDL模式(Re-DSDL)，作为比较的试验条件之一。24名被试在4种情况下进行受试者内实验:两种动态光照模式(DSDL和Re-DSDL)在两个时间段(黎明和黄昏)。因变量为心理状态、生理指标和认知表现。结果表明，总体而言，DSDL对心理状态的改善大于Re-DSDL。在黎明，参与者在DSDL中比在Re-DSDL中体验到更少的愤怒和抑郁;在黄昏时，参与者在DSDL中比在Re-DSDL中体验到更少的愤怒和活力。与Re-DSDL相比，DSDL对某些身体指标也有显著影响，但对认知表现没有影响。
