摘要
本文主要研究白炽灯的光通量测量方法。针对白炽灯的性能特点,通过比较分析光通量的两类常用的测量方法,着重介绍了基于积分球的光通量相对比较测量法,并给出了光通量的计算公式。最后指出了测量方法可能导致误差产生的原因。
The measurement of the luminous flux of an incandescent lamp is described in this paper. Aimed at characteristics of the incandescent lamp,the relative comparison method of luminous flux based on the integrating sphere is emphatically introduced and computing formulas are given. At last,possible causes of error are pointed out.
