如何选择正确的直流/直流LED驱动器
设计最佳的DC / DC LED驱动器可以提高调光性能，色彩渲染和室内和室外照明应用范围的一致性，解决一些与颜色和亮度控制的挑战。
大多数LED驱动器厂商一致认为，一旦LED被选中有四个关键规格，LED照明设计师需要知道输入电压范围，输出电压的LED串，电流和调光选项，以缩小名单的最佳LED驱动程序的应用。
其他需要研究的领域包括调光性能、显色指数（CRI）和效率。颜色亮度和渲染真实的颜色可能是更重要的零售照明，例如，颜色一致性往往是优先在高端应用中使用相同的夹具数量。
At the same time， lighting designers have to keep in mind several potential design constraints—cost， size， and thermal issues—depending on their application. For example， in high-performance， high-end applications， cost constraints will likely not be an issue. So again， keep in mind the end applications when determining the right LED driver for the job.
In addition， a lighting designer’s knowledge of power systems will come into play in the selection. Many LED vendors offer a driver portfolio that ranges from those that are simple to use， relatively speaking， to more complex devices that are packed with features and functionality that can be used by power experts. They also offer a slew of design tools and calculators for driver selection.
