三参数Weibull分布下基于BRM的LED照明灯寿命预测
Life prediction of LED lamps based on BRM under three-parameter weibull distribution
摘要
Abstract
In order to accurately obtain the life information of LED lamps in a short time,three-parameter Weibull function was applied to describing the life distribution based on three groups of constant-stress accelerated life test data.The processing and analysis on test data was achieved by Bilinear Re-gression Method (BRM),and the self-developed life prediction software was employed to precisely calculate the life of LED lamps under normal working stress.The numerical results show that the LED lamps life submits to three-parameter Weibull distribution,and the accelerated model meets the Arrhenius equation.The LED lamps’life predicted precisely can provide technical references for engi-neering technicians with regard to the product’s reliability design.关键词
