　　使用LED驱动评估板的优化改造照明设计

　　照明设计师最好能明智地使用现成的评估板或模块，它们既是照明项目的基础，又有助于加速设计周期。在某些情况下，利用数据本身可能不足以帮助你前进，尤其是设计挑战，例如，如果他们缺乏所有数据需要的供电照明系统如LED改造灯泡和照明应用选择最佳的LED驱动方案。

　　一些照明设计师面临的试验包括实现调光能力，实现高效率，选择正确的设计权衡，同时试图挤压到一个小空间的所有的电子产品。这些参考设计套件或评估板的重点是使它更容易解决这些任务，所以工程师可以快速实现LED驱动器集成电路到他们的设计。

　　我们将看看一些评估板的LED改造灯泡的项目，包括A19、PAR30 / 38、PAR20、GU10、和烛台样式的灯泡。一系列的参考设计套件和评估板可从公司如集成，向Digi-Key网站Power Integrations德克萨斯文书。

　　“LED lighting designs are really a balancing act，” said Andrew Smith， product marketing manager at Power Integrations. “There are multiple different features and requirements in different geographical regions. If this is your first time trying to manage all of these competing variables， it is extremely daunting.”

　　The role of a design evaluation board or reference design kit is to provide a design that is 75 percent completed， added Smith. “It makes it a lot easier to establish what you really need. You might have to modify a reference design， but you won‘t have to design it from scratch.”

　　Smith noted that Power Integrations’ reference design boards or kits offer a working， production-ready board. The idea is to give a designer something that looks like a real solution， which can be modified. The company‘s reference design kits include the board， schematics， Gerber files， complete bill of materials， blank boards to build a modified version of the circuit， and extra ICs to evaluate other devices in the same series， which typically provide a little more or less power. The included engineering test report also explains why specific trade-offs were made in the design.
