　　新材料技术提高LED MR16灯泡更换的流行

　　这可能是最受欢迎的灯具在使用今天最近美国能源部的报告估计，在美国就有4600万但MR16卤素灯泡是最有效的。这也使它通过更换LED厂商的高效率的一个有吸引力的目标，并且已经有10%的MR16的安装基础在美国已经切换到固态版本。

　　然而，市场上许多LED替代品都有不利的一面。美国能源部说，还有表现和等价性问题，主要是一种高流明输出的小型MR16形式因素结合的挑战。卤素灯仍然可以提供比最好的LED版本流明还要多一倍的光，其中许多仍然难以满足35瓦卤素灯的性能要求。其他的问题包括匹配“温暖”卤素颜色和高价格，特别是可调光LED版本。

　　几乎所有的主要制造商销售LED灯mr16s，仍有很多需要改进的地方。在这篇文章中，我们来看看新的半导体材料、荧光粉的组合承诺提供真正的固态替代那些耗电但流行的卤素。

　　Introduction and market data

　　Many estimates1 suggest that lighting as a whole accounts for about one-fifth of global electricity consumption， and LED-based lighting has long promised to have a major impact on that figure. At the same time， the growing popularity of MR16 halogen lamps makes them increasingly responsible for the world’s growing electricity bill.

　　Halogen lamps present extra motivation for consumers looking to switch to LED replacements. In rooms where previously a 100 Watt incandescent bulb would have been a typical choice， many may now feature six or more halogen spotlights. If each of those is rated at 50 Watts， the impact on customer bills is obvious.

　　No wonder LED-based versions of MR16s have already made significant inroads into the market for halogens. The latest figures from the US Department of Energy （DOE）， in its April 2013 report on LED lighting adoption，2 estimate that of 46 million MR16 halogens installed in the country， 4.8 million now feature LED chips.
