In order to accelerate the assessment of the expected lifespan of LED bulbs, the temperature stress accelerated life test process of LED light sources, which based on the Arrhenius e index model and the Weibull lifespan calculation model, was elaborately presented in tabular form in this paper, and the rationality and reliability of the test results were verified by using the method of linear fitting. The experimental results are in good agreement with the expected effects. Therefore, the accelerated life calculation method and verification means introduced in this paper have significant guiding significance for the assessment of the accelerated life of LED light sources.
