摘　　要：本文旨在分析一款汽车用灯具光源灯丝灯泡型式检验过程中光通量测量结果的不确定度。基于积分球光通量测试系统,从设备、环境等方面分析了影响检测结果的不确定因素,使用测量模型对测量不确定度进行评定,计算出A类、B类不确定度,经过合成,得到在一定的置信区间下的扩展不确定度。该评定过程可为从事汽车灯具型式认证的相关人员借鉴和参考。The purpose of this paper is to analyze the uncertainty of the luminous flux measurement results during type approval tests of a filament bulb,a light source for automotive lamps.Based on the integrating sphere luminous flux test system,the factors affecting the uncertainty of the results are analyzed in terms of equipment,environment,and so on.Measurement uncertainty was evaluated using a measurement model,and Type A and Type B uncertainties were calculated and combined to obtain the expanded uncertainty at a certain confidence interval.The evaluation process can be used as a reference for those involved in type approval of automotive lamps.
