如何选择合适的LED照明电源

　　如何选择合适的LED照明电源

　　随着高亮度LED的扩散，为商业和家用照明提供替换灯，电源供应解决方案也会出现同样的（如果不是更大的）扩散。从几十个厂家的数百种产品，它就变成了一个问题：如何使输入/输出电压和输出电流/额定功率的所有排列的感觉，说的机械尺寸/终端类型和调光，许多其他功能没有远程控制和保护电路，提供。本文旨在解开不同类型LED电源的奥秘，以及它们如何运作，以简化选择过程。

　　有助于了解各种解决方案，本文将参考一些容易从Digi-Key提供的产品，包括交流/直流艾默生网络能源公司和崔转换器模块、降压模块和降压-升压模块电源，升压板的建议，从TDK Lambda和Microsemi。

　　Understand your LED lighting application first

　　In order to determine the type of power supply best suited for a particular lighting project， it is first necessary to understand the nature of the application， i.e. what form the LED lighting will take and where and how it will be deployed. There is no unique segmentation， but the ‘where’ usually relates to the broad market， while the ‘what’ or ‘how’ is more about the function or characteristic of the lighting. Typical market segments for lighting are retail， industrial， and architectural along with the terms ‘indoor’， covering commercial and residential use， and ‘outdoor’ for street lighting and building illumination. Already there is an overlap in these descriptions， so it is probably more helpful to explore a few examples in a little more detail to appreciate what they may require from a power supply.
