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.
