摘　　要：本文在调研LED照明产品国际和国家标准有关寿命评价考虑的基础上,介绍了目前针对LED寿命测试的相关研究工作,对LED照明产品的寿命评估方法做了探索性研究。经分析可知,采用寿命测试推算方法,IESTM21和边界函数法均存在一定的问题。研究表明,采用试验条件加速的方法来测试推算LED照明产品的寿命存在较高的可行性,且此评价方法可显著缩短产品的寿命评价周期。On the basis of the survey research on lifetime evaluation considerations in international and national standards for LED products, current lifetime researching status is analyzed, and the initial experiment research is performed. According to the analysis and experiment results, there would be some problems to apply IES TM21 and border function method to evaluate the lifetime of LED lighting products. Our research shows that accelerated experimental conditions would be a reasonable way with high feasibility to test and evaluate the lifetime of the overall LED lighting products, and the cycle of lifetime assessment could be shorten significantly
