读写作业台灯光度性能标准对比与分析

Comparison and Analysis of Luminosity Performance Standards of Reading and Writing Desk Lamps

读写作业台灯光度性能是评价台灯质量好坏的重要指标,本文通过对比GB/T 9473—2017和GB/T 9473—2022两份标准的光度性能要求和测试方法,分别采用对应的试验装置对不同光学结构的台灯进行光度性能测试。从新旧标准测试结果可反映出GB/T 9473—2022光度等级评价和矩形区域测试方法与GB/T 9473—2017扇形光度等级评价和测试方法相对比更为严苛,新标准测试点位相对更多,准确度相对更高。同时新标准在测试范围方面,更注重对整体矩形工作区域照明的考虑,更符合目前主流课桌面的外形与实际照明需求。

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 94732022 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 CB/T 94732022 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.
