摘要
本文旨在探讨瞄点式亮度计与成像亮度计在台灯表面亮度测量中的应用.通过对比分析两种亮度计的工作原理、测量特点及其在台灯表面亮度测量中的实际应用,试验方法参照标准GB/T 9473-2022,得到两种亮度计的在实际测量中的优势和局限性.实验结果表明,成像亮度计全面反映表面亮度的分布情况,在复杂表面亮度测量中更具优势,而瞄点式亮度计适用于局部亮度的精确测量.
Abstract
This article aims to explore the application of spot luminance meter and imaging luminance meter in measurement of surface brightness of table lamps.By comparing and analyzing the working principles,measurement characteristics of two types of luminance meters,and practical applications in the measurement of surface brightness of table lamps,the advantages and limitations of the two luminance meters in practical measurement are obtained.The experimental method refer to the national standard GB/T 9473-2022.The experimental results show that the imaging luminance meter canfully reflect the distribution of surface brightness and has more advantages in the measurement of complex surface brightness,while the spot luminance meter is suitable for precise measurement of local brightness.
