【摘要】 介绍了一种用积分球、硅光电池作探测器件来测试车灯光通量性能的检测仪器。文中阐述了该系统的设计思想。仪器采用微机控制，自动完成数据采集、标准判别及打印测试结果。相对误差小于５％，完全满足国标对车灯性能测试的要求，投入使用以来，取得了良好的实用效果，是汽车行业理想的检测仪器。更多还原

【Abstract】 The paper introduces a device of testing luminous flux of vehicle lamp with integrating sphere and selenium cell as detector,and gives design thought of this system.The devices is controlled by microcopmuter,and its data acquisition,standard discriminant and priniting of the results are completed automtically.With relative error less than 5%, the international performance index of vehicle lamp is achieved. A good practical effect is showed when running a ideal test device in vehicle industry。更多还原
