  色彩质量标准的理论基础

  CIE颜色渲染指数(CRI)与视觉评价没有很好的关联,在许多情况下,都会涉及到几个已知的问题。这篇文章回顾了这些问题,并解释如何NIST的颜色质量尺度(CQS)解决他们。

  这篇文章的目的是征求意见的固态照明(SSL)在颜色质量规模工业(CQS)由美国国家标准与技术研究所(NIST)的开发。CQS正在讨论作为一个在国际委员会的建议对照明(CIE)技术委员会(TC)1-69和最后的讨论正在进行中的TC对选择一个新的度量。由于SSL行业在TC中没有很好的代表性,我们希望将SSL行业的意见传达给委员会成员。

  SSL产品的颜色质量是至关重要的,并日益受到人们的关注。CIE显色指数(CRI)[ 1 ]已被广泛使用多年。然而,CRI与CRI 40岁和各种问题时,用发光二极管(LED)的来源已经确定,在[ 2 ]许多刊物报道。特别是,由CIE技术委员会TC 1-62的报告,“色性白光LED光源”[ 8 ],总结了CRI的几个问题在应用于白光LED光源。中国国际广播电台1不在许多情况下,相关的视觉评价。根据TC 1-62的结论,一个技术委员会TC 1-69(彩色再现的白色光源,主持:W. Davis)是在2006开发并推荐一种新的CIE度量了。

  The new metric is intended to eventually replace the CRI (not immediately after publication of the new standard)。 It should work well for both traditional lighting technologies and SSL sources. At NIST, we have developed the CQS [9-11], which addresses the problems of the CRI for SSL sources, yet maintains good consistency of scores with the CRI for traditional sources, and have proposed it to TC 1-69. Our spreadsheet to calculate CQS has been distributed to many users in the SSL industry and continues to gain support in the USA. However, the CQS is currently not gaining good support in the TC. The TC is inclined to adopt a different metric, which is a pure fidelity metric very similar to CRI. The traditional lamp industry also has concerns that the concept underlying the CQS deviates from the CRI. We are concerned that another pure fidelity metric will not solve the problems for SSL sources, and we believe that a new concept metric, such as the CQS, is needed for the SSL industry.
