Luminaires that employ both a direct and indirect lighting component have the potential to optimally benefit both the visual and non-visual aspects in lighting designs. This type of luminaire, however, still spans a huge range of possible implementations with variations in the ratio of direct/indirect light and in the distribution of the light across the ceiling, all with their respective benefits and downsides. However, the effects of all these variations on for example preference and general appreciation are not well known. In the current study, we investigated the ratio of direct/indirect light and of lighting distribution on the ceiling in an open-plan office setting while keeping work-plane illuminance constant, and measured their impact on room appraisal, atmosphere, and visual comfort. In general, more indirect light and a more uniform ceiling distribution were appreciated, but not for all participants to the same extent. Participants could be classified into two main groups, where in the first group higher perceived brightness corresponded with more positive appraisals and comfort – this group responded well to more indirect light and more uniform distribution – whereas the second group appeared to dislike a bright environment and was less sensitive to ratio and virtually insensitive to uniformity manipulations.

将天花板置于中心舞台——直接/间接照明对房间评估的影响

采用直接和间接照明组件的灯具有可能在照明设计中最大限度地有益于视觉和非视觉方面。然而,这种类型的灯具仍然涵盖了大量可能的实施方式,在直接/间接光的比率和穿过天花板的光分布方面存在差异,所有这些都有各自的优点和缺点。然而,所有这些变化对例如偏好和普遍欣赏的影响并不为人所知。在当前的研究中,我们调查了开放式办公室环境中直接/间接光的比率和天花板上的照明分布,同时保持工作平面照度不变,并测量了它们对房间评价、氛围和视觉舒适度的影响。一般来说,更多的间接光和更均匀的天花板分布受到赞赏,但并非所有参与者都达到同样的程度。参与者可以分为两个主要组,在第一组中,较高的感知亮度对应于更积极的评价和舒适度——这组对更多的间接光和更均匀的分布反应良好——而第二组似乎不喜欢明亮的环境,并且对比率不太敏感,对均匀性操作几乎不敏感。
