In this paper, based on the study of accelerated life testing) methods, a novel evaluating method of the reliability of LED luminaries was proposed on the basis of fuzzy algorithmic approach. In this method, the different factors which affected the LED luminaries were evaluated by fuzzy comprehensive evaluation model, combining Analytic Hierarchy Process theory and based on experts' scorings, the distributing weight vector of every factor can be determined by qualitative and quantitative analysis, and then the lifetime of LED luminaries will be calculated through fuzzy algorithmic approach. The main advantage of this method is that different factors which affected the reliability of LED luminaries were considered.
