摘　　要：为研究积分球系统和分布光度计系统测量光通量的差异以及造成差异的影响因素,本文以LED筒灯为对象,采用控制变量法设计实验。首先,简要介绍两套系统的测量原理。接着,描述样品的选择和实验过程。然后,分析两套系统的测量不确定度。最后,对实验结果进行分析。实验结果表明:灯具尺寸越大,光束角越小,两套系统测得的光通量差异越大,而色温对光通量差异的影响并不明显。即灯具在两套系统之间测量的光通量差异与灯具的尺寸和光束角有关而与色温无关。To study the difference and the influencing factors that cause the difference of the luminous flux measurement between the integrating sphere system and the goniophotometer system, this paper adopts the controlled variable method to design the experiment taking LED downlight as the object. First, this paper briefly introduces the measurement principles of the two systems. Next, the sample selection and experimental process are described. Then, the measurement uncertainty of the two systems is analyzed. Finally, the experimental results is analyzed. The experimental results show that the larger the size of the lamp, the smaller the beam angle of the lamp, and the greater the difference in luminous flux measurement by the two systems. However, the effect of color temperature on the difference in luminous flux measurement is not obvious. The experimental results show that the larger the size of the lamp, the smaller the beam angle of the lamp, and the greater the difference in luminous flux measured by the two systems. However, the effect of color temperature on the difference in luminous flux measurement is not obvious. That is, the difference in luminous flux measurement between the two systems is related to the size and beam angle of the luminaire, but not to the color temperature.
