Ensaios acelerados em sinaleiros LED (diodo emissor de luz) e incandescentes de painéis com alimentação 220Vac para análises de confiabilidade

Abstract

This work involves the application of accelerated tests on pilot lights diameter of 22mm for panels, which feature LED technology and incandescent, supplied directly into 220Vac, aiming to compare the durability and reliability of both, for taking strategic maintenance decisions, investments and supplies. Failure data collected were processed using quantitative life data analysis and determination of activation energy parameters and reliability with ALTA™ Software aid. The durability of LED lamps and proximity average life values indicated by the manufacturer of incandescent lamps were proven in the accelerated tests.
