摘　　要：针对某些技术文件中普遍存在的LED光源与LED灯具技术指标混淆不分的现象,指出满足照明需求的配光是对LED灯具的要求,而不是对LED光源的要求;而流明维持率应是LED光源要完成的试验。同时说明了LED灯具应满足的经典的性能项目。强调LED灯具的高效能应以满足经典的性能要求为前提条件,不能以牺牲照明环境舒适性和可靠性的代价来追逐LED灯具效能。In allusion to the phenomena of technical requirements confusion between LED light source and LED luminaire in some specifications, this article indicates that light distribution which meets the lighting requirements is suitable to a LED luminaire, not to a LED light source, whereas lumen maintenance is the test item for LED light source. At the same time, the article points out the sutra performance items which LED luminaires should fulfill. It emphasizes that high LED lurninaire efficacy should base on the precondition of fulfilling the sutra performance items and that well luminaire efficacy but poor lighting conformity and reliability is unacceptable.
