| 摘 要： | 光通量是光源重要的性能参数。主要研究了自吸收效应在不同光源光通量测量中的影响。同时对测试过程中出现的问题进行了分析说明，特别是如何获得准确的自吸收系数。通过试验发现，采用辅助灯来进行自吸收修正，能够得到更准确的光源光通量值。

| Abstract: | The luminous flux of light source is an important performance parameter. In this paper the effect of selfabsorption on the luminous flux measurement results of various light sources is well studied. The problems existing in the measurement process are explained, especially figuring out how to obtain the self-absorption coefficient precisely. It is found that the use of auxiliary lamp is necessary for the self-absorption correction and for measuring the luminous flux of luminaries accurately. |
