本文提出了一项初步研究，调查了平均房间表面出口作为空间亮度和感知照明充足度预测指标的适用性，然后将这些结果与水平照度在相同条件下对这两个项目的预测结果进行了比较。该实验包括26名参与者。书房用了一间小办公室。它将参与者暴露在三个平均房间表面出口的水平面上，每个水平面上都有三种不同的光分布和三种不同的表面反射率，总共产生27个光场景。平均房间表面出口与感知照度充足性和空间亮度之间存在明显的关系，但水平照度与两者之间没有明显的关系。在报告的空间亮度水平和报告的感知照明充足程度之间绘制了相关性。
This paper presents a pilot study that investigated the suitability of mean room surface exitance as a predictor of spatial brightness and perceived adequacy of illumination, and then compared these results with how horizontal illuminance predicted both items under the same conditions. The experiment included 26 participants. A small office was used for the study. It exposed participants to three levels of mean room surface exitance, each delivered with three different light distributions and across three different surface reflectances, resulting in a total of 27 light scenes. A clear relationship existed between mean room surface exitance and both perceived adequacy of illumination and spatial brightness, but not between horizontal illuminance and either item. Correlations were drawn between reported levels of spatial brightness and reported levels of perceived adequacy of illumination.
