突破性LED降低照明系統(tǒng)的尺寸和成本

　　對于任何照明系統(tǒng)設計者來說，最大的問題是設計復雜性和成本。他們也是LED照明采用的最大障礙。幸運的是，LED制造商正在解決這兩個問題，在一些新的方法：他們正在尋找更好的散熱，開發(fā)板上的芯片（玉米芯）設計，提高光輸出。此外，供應商已經(jīng)取得了性能和成本的突破，通過開發(fā)新的架構(gòu)和設計，做了一些有用的事情，如提高光輸出，減少空間，降低成本，降低設計復雜度。

　　后者的例子包括Cree公司的新技術平臺，雙打SC5大功率LED的光輸出顯著降低成本，和飛利浦Lumileds公司的Luxeon COB生產(chǎn)線，最近加入的Luxeon COB 1202s說提供領先的中心束燭光（CBCP）在一個緊湊的陣列。公司的Luxeon COB陣列crispwhite技術被稱為“改變游戲規(guī)則”的零售筒燈和射燈。然而，它不是全部關于美學。Luxeon COB陣列降低燈具設計成本和降低要求的散熱器。

　　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.”
