LED標準的發展遠未結束

　　標準的制定是單調乏味的工作，但關鍵要保證性能和安全性的基于LED的照明可以為國際認可的基準測試和表征。此外，使用國際標準鼓勵更好的照明設計和鞏固消費者對LED產品的信心。

　　早期，LED的標準缺乏造成市場混亂。從一個制造商到另一個制造商的測試方法和術語的變化使得很難比較新的LED產品與其他光源，以及與其他LED產品從不同的制造商。

　　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.
