摘　　要：对金属卤化物灯初始光效的测量不确定度进行评定,分析了不确定度的主要来源,通过功率测量不确定度分量和初始光通量不确定度分量得到合成不确定度,最后计算出金属卤化物灯初始光效的测量扩展不确定度为1.04(lm/W),为提高金属卤化物灯初始光效测量的有效性提供了可靠的理论依据。The uncertainty in measurement of initial luminous efficacy for metal halide lamps was accessed.The main source of the uncertainty was analyzed and the uncertainty in of power and initial lumen was tested to get the combined uncertainty.At last, the uncertainty in measurement of initial luminous efficacy for metal halide lamps was calculated as 1.04 （lm/W） , which provide the reliable theoretical basis for improving the validity in measuring the initial luminous efficacy for metal halide lamps.
