如何選擇正確的直流/直流LED驅(qū)動器

　　設(shè)計最佳的DC / DC LED驅(qū)動器可以提高調(diào)光性能，色彩渲染和室內(nèi)和室外照明應(yīng)用范圍的一致性，解決一些與顏色和亮度控制的挑戰(zhàn)。

　　大多數(shù)LED驅(qū)動器廠商一致認(rèn)為，一旦LED被選中有四個關(guān)鍵規(guī)格，LED照明設(shè)計師需要知道輸入電壓范圍，輸出電壓的LED串，電流和調(diào)光選項，以縮小名單的最佳LED驅(qū)動程序的應(yīng)用。

　　其他需要研究的領(lǐng)域包括調(diào)光性能、顯色指數(shù)（CRI）和效率。顏色亮度和渲染真實的顏色可能是更重要的零售照明，例如，顏色一致性往往是優(yōu)先在高端應(yīng)用中使用相同的夾具數(shù)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.
