LED标准的发展远未结束

　　LED标准的发展远未结束

　　标准的制定是单调乏味的工作，但关键要保证性能和安全性的基于LED的照明可以为国际认可的基准测试和表征。此外，使用国际标准鼓励更好的照明设计和巩固消费者对LED产品的信心。

　　早期，LED的标准缺乏造成市场混乱。从一个制造商到另一个制造商的测试方法和术语的变化使得很难比较新的LED产品与其他光源，以及与其他LED产品从不同的制造商。

　　However， in recent years， organizations such as the U.S. Department of Energy （DOE） have worked closely with standards-setting bodies to accelerate the development and implementation of a suite of standards for solid-state lighting （SSL）。 Groups such as the Illuminating Engineering Society （IES）， the National Electrical Manufacturers Association （NEMA）， Underwriters Laboratories （UL）， and the International Electrotechnical Commission （IEC） have been collaborating for over a decade. The result of their labors is a family of standards and methods familiar to engineers working with LEDs. However， the work is far from complete and several additional standards have reached an advanced stage of development.

　　This article summarizes the main standards that apply to contemporary commercial LEDs and LED-lighting fixtures and looks at standards that are currently being drafted and will further improve the quality， reliability， and safety of LEDs.
