工作场所照明设计主要是由低亮度灯具的感知要求，以避免分散反射在显示屏设备（DSE）。本文介绍了目前市售的DSE的反射特性的测量。结果表明，现代显示屏引起较少的干扰反射，因此，目前的工作场所照明准则可以显着放宽。屏幕自发光、镜面反射和漫反射的测量遵循EN 29241-7的实验方法，并证实了在以前的研究中看到的趋势。EN 29241-7包含量化办公室工作人员主观分心影响的计算，这些计算适用于导出办公室灯具最大可容忍亮度的数值。这些测量技术的商业工作场所照明设计的实际应用进行了讨论。
Workplace lighting design is dominated by a perceived requirement for low-brightness luminaires, to avoid distracting reflections in display screen equipment (DSE). This paper presents measurements of the reflectance characteristics of current commercially available DSE. The results suggest that modern display screens cause less distracting reflections, and consequently that current workplace lighting guidelines could be significantly relaxed. The measurements of screen self-luminance, specular and diffuse reflectance followed the experimental method of EN 29241-7, and corroborate tendencies seen in previous studies. EN 29241-7 contains calculations for quantifying the subjective distraction effect to office workers, and these calculations were adapted to derive numerical values for the maximum tolerable luminance of office luminaires. The practical application of these measurement techniques to commercial workplace lighting design is discussed.
