ABSTRACT

This tutorial article provides a comprehensive overview of the development and use of ANSI/IES TM-30-20, an American National Standard method for evaluating light source color rendition that is published by the Illuminating Engineering Society. Five years since its initial publication, TM-30 is increasingly used by lighting producers, specifiers, and researchers due to its superior accuracy and the expanded scope of provided information compared to predecessor tools for assessing color rendition. Making the most of these improvements requires people who use the method to be more knowledgeable and intentional, and this tutorial consolidates a range of information to assist with best practices. The article, arranged as a series of questions, includes information about the development of the standard, color rendering fundamentals, TM-30 measures and their meaning, TM-30 calculation details, and application of TM-30. The document does not provide instructions for performing TM-30 calculations, which is the purpose of the ANSI/IES TM-30-20 standard, which is freely available.

摘要

本教程文章全面概述了 ANSI/IES TM-30-20 的开发和使用，ANSI/IES TM-30-20 是由照明工程学会发布的用于评估光源颜色再现的美国国家标准方法。自首次发布五年以来，TM-30 越来越多地被照明生产商、规范制定者和研究人员使用，因为与以前用于评估色彩再现的工具相比，它具有卓越的准确性和提供的信息范围扩大。充分利用这些改进需要使用该方法的人更有知识和更有意识，本教程整合了一系列信息以协助最佳实践。这篇文章被安排为一系列问题，包括有关标准发展、显色基础知识、TM-30 措施及其含义，TM-30 计算细节，以及 TM-30 的应用。该文档不提供执行 TM-30 计算的说明，这是免费提供的 ANSI/IES TM-30-20 标准的目的。
