Análise de vida acelerada em diodos emissores de luz aplicados em medidores eletrônicos de energia elétrica

Abstract

This paper presents a study of Accelerated Life Testing to two suppliers of electronic components used in electricity meters. The rated component is the Light Emitting Diode (LED) and the main objective is the statistical analysis of test results after the application of temperature and moisture stimuli in several samples of LEDs. Finally, replacement of currently approved by a supplier that has higher performance and lower cost is proposed. It will be used as a reference standard NBR 16078: 2012.
