Application of Luminance Meter in the Measurement of the Surface Brightness of Table Lamps
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.
