Comparison and Analysis of Luminosity Performance Standards of Reading and Writing Desk Lamps
YAN Wenping
Abstract：The luminosity performance of reading and writing desk lamps is an important indicator to evaluate the quality of desk lamps.In this paper,the luminosity performance requirements and test methods of GB/T 9473-2017 and GB/T 9473-2022 standards are compared,and the corresponding test devices are used to test the luminosity performance of desk lamps with different optical structures.The test results of the new and old standards can reflect that the GB/T 9473-2022 photometric grade evaluation and rectangular area test method are more stringent than the GB/T 9473-2017 sector photometric grade evaluation and test method,and the new standard has more test points and higher accuracy.At the same time,in terms of the test range,the new standard pays more attention to the consideration of the overall rectangular working area lighting,which is more in line with the shape and actual lighting needs of the current mainstream desk surface.
