如何選擇合適的LED為高灣照明

　　高灣照明市場正在準備一個大的轉變LED技術。這是由LED燈的價格下降，以及傳感器和控制的進步，這是用來幫助進一步降低能源消耗，使投資回報率（ROI）。高灣照明在商業和工業環境中的應用現在很好地利用LED在節約能源方面的優勢，并盡量減少停機時間。

　　Navigant的研究（Boulder、CO）預測，全球銷售高灣燈具將增加到2017，幾乎達到170億美元，主要由更昂貴的LED燈具在新建和改造的采用率將上升。

　　Navigant的研究指出，LED技術的改進也推動了這一轉變，使LED照明這些滿足廣域空間”的嚴格要求，同時最大限度地減少對比度，減少眩光，并在許多情況下，滿足嚴格的安全和危險環境的要求。”。

　　For lighting designers to develop the most cost-effective luminaires that take advantage of LED technology， they need to select the right emitters for the job. These LEDs must be able to meet high-output lumen requirements while simplifying heat management and delivering the right amount of light distribution.

　　There are many ways to integrate LEDs into high-bay luminaire applications， and there are a number of considerations and/or trade-offs for designers that range from thermal designs （heatsinking） and optical control to driver selection and pricing. Designers of high-bay lighting systems may also want to start looking at incorporating sensors， networking， and other advanced lighting controls to further energy savings and cost reductions， but that is beyond the scope of what we are exploring here. In this article we will take a look at several LED solutions that meet the performance， as well as deliver the cost savings required for high-bay applications， including Cree‘s XLamp XM-L2 and XLamp XP-E2 and Philips Lumileds’ Luxeon R and Luxeon TX.
