摘要
光效是衡量LED灯具将电能转化为光能的重要指标,对于同一LED灯具,采用不同光度测量系统测得的结果会有差异,且测量不确定度也会有所差异.本文以LED吸顶灯为例,基于分布光度计测量系统探讨影响光效测量结果的因素,对该系统测量LED灯具光效的测量不确定度进行评定.
Abstract
Light efficiency is an important indicator for measuring the conversion of electrical energy into light energy in LED lighting luminaires.For the same LED lighting luminaires,the results obtained using different photometric measurement systems may be different,and the measurement uncertainty may also be different.Taking LED ceiling lights as an example,this article explores the factors that affect the measurement results of light efficiency based on the distributed photometric measurement system,and evaluates the measurement uncertainty of the system for measuring the light efficiency of LED lighting luminaires.
