　　突破性LED降低照明系统的尺寸和成本

　　对于任何照明系统设计者来说，最大的问题是设计复杂性和成本。他们也是LED照明采用的最大障碍。幸运的是，LED制造商正在解决这两个问题，在一些新的方法：他们正在寻找更好的散热，开发板上的芯片（玉米芯）设计，提高光输出。此外，供应商已经取得了性能和成本的突破，通过开发新的架构和设计，做了一些有用的事情，如提高光输出，减少空间，降低成本，降低设计复杂度。

　　后者的例子包括Cree公司的新技术平台，双打SC5大功率LED的光输出显着降低成本，和飞利浦Lumileds公司的Luxeon COB生产线，最近加入的Luxeon COB 1202s说提供领先的中心束烛光（CBCP）在一个紧凑的阵列。公司的Luxeon COB阵列crispwhite技术被称为“改变游戏规则”的零售筒灯和射灯。然而，它不是全部关于美学。Luxeon COB阵列降低灯具设计成本和降低要求的散热器。

　　One of the big changes happening in the LED industry is the move by some LED manufacturers to focus on other components like the heatsinks， optics， and printed circuit boards （PCBs） in the LED lighting system to lower total system cost. One of the biggest proponents of this approach is Cree Inc. “There is a general understanding still in the LED lighting community that came from historical truth that LEDs used to be the most expensive part of the system and so whoever could buy the cheapest LED had the cheapest system，” said Paul Scheidt， leader of product marketing， LED components， Cree. “That used to be true about three or four years ago， but the cost of LEDs have come down to such a point where LEDs are no longer the most expensive part of the system.”
