New LED Luminous Flux Test System and Its Error Analysis

Abstract

Abstract-With the continuous improvement of LED luminous efficiency, in the field of general lighting, there is a tendency to replace traditional light sources. But the lack of common standards for LED optoelectronic performance has become a major factor hindering its development. Among them, the luminous flux data is very important not only for determining the LED luminous efficiency and other performance parameters, but also for LED marketing and widely used.
