摘　　要：要提升室内照明的质量,保证“LED照明建筑一体化”的设计水平,照明设计和评价应由单一的水平方向向整体空间需求转变。EN12464—2019针对室内的空间照度进行了规定,提出了柱面照度、墙面照度、顶棚照度的要求,但是目前我国标准对于室内照明场所垂直方向的照度没有明确的规定。为研究垂直照度的合理取值,本文开展了垂直照度与辨识度的实验研究。实验结果表明,达到可识别的程度时所需的垂直照度与背景照明的色温和亮度有着密切的关系,通过分析得到了不同色温条件下垂直照度与背景亮度的关系曲线。To improve the quality of indoor lighting and ensure the“LED lighting architecture integration”design,lighting design and evaluation should shift from horizontal to spatial demand.EN12464—2019 proposedēz,ēm,wall,ēm,ceiling as the space lighting indicator,but there is no stipulation on vertical illumination in domestic standard at present.To study the reasonable value of vertical illumination,the experiments on vertical illumination and identification are carried out in this paper.The experimental results show that there is a close relationship between the vertical illuminance and the background lighting’s color temperature and luminance.The relation curves between vertical illuminance and background luminance under different color temperature were obtained finally.
