| 摘 要： | 为了在短时间内准确获得LED照明灯的寿命信息,以3组恒定加速应力的试验数据为基础,采用三参数Weibull函数描述其寿命分布,基于双线性回归法(BRM)对试验数据进行处理分析,并利用自行开发的寿命预测软件较为精确地得出LED照明灯在正常工作应力下的寿命。数值结果表明,LED照明灯的寿命服从三参数Weibull分布,其加速模型符合Arrhenius方程,精确预测的LED照明灯寿命为工程技术人员关于产品的可靠性设计提供技术参考。 |

| 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 Regression 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 engineering technicians with regard to the product's reliability design. |
