摘　　要：LED灯具中光源具有很长的寿命,如何用相对较短时间的测试结果预测很长的寿命,长期缺少权威的依据。本文参照IESTM-21的标准介绍可能用于预估LED灯具光源流明维持寿命的一种方法,供业界参考。In spite of long lifetime of LED lighting source, there has been shortage of authoritative basis to predict its long lifetime by the results tested within a shorter time. In the paper, a possible method for predicting luminous maintenance of LED lifetime was introduced for reference based on the standard IES TM-21
