GB/T 7922-2023
Introduction
The GB/T 7922-2023 Measurement Method for Lighting Source Color is a standard developed by the National Standardization Administration of China (SAC) to provide guidelines for measuring the color of lighting sources. This standard outlines the procedures and requirements for accurately assessing the color properties of lighting sources, including color temperature, color rendering index (CRI), and chromaticity coordinates.
The measurement method described in this standard employs various instruments and techniques to ensure precise and consistent color measurements. It covers the use of spectrophotometers, colorimeters, and other relevant equipment to evaluate the spectral power distribution and color characteristics of different lighting sources.
The objective of this standard is to establish a reliable and uniform methodology for measuring the color of lighting sources, enabling manufacturers, researchers, and consumers to compare and evaluate the color performance of different light sources accurately. The standard not only facilitates the proper selection of lighting products for specific applications but also contributes to the advancement and standardization of the lighting industry as a whole.
The GB/T 7922-2023 Measurement Method for Lighting Source Color is an essential reference for lighting manufacturers, testing laboratories, and quality control organizations, ensuring that lighting products meet the required color specifications and performance standards. By adhering to this standard, stakeholders in the lighting industry can ensure the consistent and accurate measurement of lighting source colors, promoting consumer confidence and facilitating fair competition in the market.
