Abstract

LED luminaires, the research object, is the new energy industry products. And aiming at the lifetime prediction and reliability evaluation of LED luminaires, a novel dual-stress accelerated life tests were designed and lifetime models were developed. The temperature and vibration were selected as the test stresses and loaded on the test samples simultaneous. According to the experimental results, life curve of LED luminaires obey to exponential model and the method can assess the reliability, quickly and effectively. The precision and accuracy of lifetime model was validated by means of variance analysis.
