摘　　要：光通量是评价照明产品极其重要的参量,通常测试灯具的光通量的设备主要有积分球测试系统和分布光度计测试系统两种。通过实例分析,对利用分布光度计系统和积分球系统测试光通量的差异进行了比较。结果表明,两种测试系统有其各自的适用对象,在以后的测试中可以根据样品的实际情况来选取最优的测试方案。Luminous flux is an important parameter to evaluate lighting products. In general, there are two kinds of test equipments to test the luminous flux of lamps, namely integrating sphere test system and distribution photometer test system. Troungh an example, the differences of measuring the luminous flux with integrating sphere system and distribution photometer system are compared. The results show that the two test systems have their own applicable object, so the optimal test scheme should be selected according to the actual situation of samples in the future.
