A Fuzzy Comprehensive Evaluation Method for Life-span of LED Lamps Based on Rough Set Theory
Abstract
The evaluation of led lamp life has always been a difficult problem. This paper proposes a fuzzy comprehensive evaluation of rough set theory. The results show that the method can quickly and accurately judge the four factors that affect the LED light source, driving power supply, heat dissipation system and use environment of LED lamps and lanterns.
