读写作业台灯照明检测影响因素分析

Analysis of Influencing Factors of Reading and Writing Desk Lamp Lighting Detection

不同的检测方法对读写作业台灯的照明结果影响很大,尤其是读写作业台灯在不同状态下对应的照明结果是截然不同的。本文依据标准要求针对性设计一款专门用于检测台灯照明质量的试验装置,将重点解决读写作业台灯在照度、照度均匀度和遮光性试验过程中,存在的台灯出光面仰角大小,以及出光面几何中心点的垂直投影点难以确定的问题,以提高台灯照明质量检测的准确性与检测效率。同时对比分析不同安装位置、安装高度和发光面仰角对台灯照明测试结果的影响。

Different detection methods have a great impact on the lighting results of reading and writing desk lamps,especially the corresponding lighting results of reading and writing desk lamps in different states are completely different.This paper designs a test equipment specifically for testing the lighting quality of desk lamps according to the standard requirements.In the process of illuminance,illuminance uniformity and shading test of reading and writing desk lamps,it is difficult to determine the elevation angle of the light surface and the vertical projection point of the geometric center point of the light surface,so as to improve the accuracy and efficiency of the lamp lighting quality detection.At the same time,the influence of different installation position,installation height and elevation angle of a luminous surface on the test results of table lamp lighting is compared and analyzed.
