    An evaluation method for the reliability of Light Emitting Diode(LED) lamps was established based on fuzzy comprehensive evaluation algorithm. Firstly, the major factors which affect the reliability of LED lamps were studied from three aspects on the LED light source, heat-removal system and working environments, and a factor set and an evaluating set for the LED lamp lifetime were built up at the same time. Then, the weighing coefficient of each factor was obtained based on Delphi evaluation method. Finally, the evaluation model for the reliability of LED lamps was built up by choosing appropriate fuzzy operators. The reliability of a LED streetlight lamp was evaluated using the evaluation model. The results show that the designed model can evaluate the reliability of LED lamps quickly and effectively. It not only can save the experiment cost, but also can provide the foundation for screening failure products and managing product quality.
