度量是一种定义良好的度量，设计人员可以使用它来评估设计。多年来，在一般照明实践中最广泛使用的指标是平均照度、相关照度均匀性、日光系数、光源的相关色温和CIE通用显色指数、统一眩光等级和装置的功率密度。所有这些度量都有局限性，结果是现在有许多提议用更适合于提供更好的照明的度量来代替它们。本文基于2014年7月15日在伦敦举行的LRT研讨会上的演讲，考虑了指标的理想属性，总结了拟议的新指标，并考虑了它们被采用的可能性，如果是，它们是否可能导致更好的照明。
A metric is a well-defined measure that a designer can use to evaluate a design. For many years, the most widely used metrics in general lighting practice have been the average illuminance, the associated illuminance uniformity, the daylight factor, the correlated colour temperature and the CIE General Colour Rendering Index of the light source, the Unified Glare Rating and the power density of the installation. All these metrics have limitations with the result that there are now many proposals for replacing them with metrics more suited to delivering better lighting. This paper, which is based on the presentations given at the LRT symposium held in London on the 15 July 2014, considers the desirable attributes of a metric, summarises the proposed new metrics and considers how likely they are to be adopted and, if they are, whether or not they are likely to lead to better lighting.
