远程荧光粉提供白光LED替代品
白光LED是由许多LED灯具的核心组成的，它是由LED的蓝光和荧光灯中的黄色光混合而成的。当多个发光二极管组合在一个固定装置中时，白色固态灯可以产生足够的照明，以与白炽灯泡相媲美，而工作效率更高，持续时间更长。
然而，在追求更大功效的同时，白光LED却成为绊脚石。这种荧光粉离模具很近，一些材料的光子直接回到LED中被吸收，大大降低了发光亮度。
本文描述了解决这个问题的另一种技术的发现和商业化。被称为“远程荧光粉，“技术现在提供给设计师们希望提高自己产品的功效，而受益于一种材料的优点，可以注塑成各种形状以提高照明美学。
Chasing efficacy
LEDs are sTIll a young technology， but one that is maturing quickly. In the lighTIng sector， for example， analyst DisplaySearch notes that while LED penetraTIon was limited to just 1.4 percent in 2010， it is set to expand to 9.6 percent by 2014.1
This rapid increase in market share is in part due to falling prices and， in part， due to improving efficacy. This means that fewer， less-expensive LEDs are required per fixture to generate the same luminosity as the devices of several years ago （or the same number can produce a much brighter light for the same power input）.
