什么是色彩质量表 (CQS)

色彩质量表(CQS)是照明行业使用的一种度量系统,用于评估 光源的色彩质量特别是 固态照明.它是作为显色指数(CRI)的替代品而开发的,以解决显色指数的局限性和诟病。CRI 最初是为荧光灯和白炽灯设计的,但在应用于 LED 灯时被发现并不可靠。

CQS 由美国国家标准与技术研究院 (NIST) 于 2010 年开发,旨在更准确地测量固态照明光源的显色能力。CRI 只评估八种不饱和的柔和色彩,而 CQS 则不同,它评估的 15 种颜色更准确地代表了扩大色域的正常物体色彩范围。这组扩大的色彩样本使 CQS 能够提供更全面、更准确的照明效果。 对显色性的细致评估.

CQS 值以 0-100 为单位计算,与 CRI 相似,因此易于理解和比较。CQS 考虑了色彩辨别力和人类偏好等因素,提供了更全面的色彩质量评估。它旨在对光源准确再现照明物体色彩的能力进行量化衡量,从而更准确地反映真实世界色彩的鲜艳度和保真度。
