飛思卡爾DALI、DMX512A參考設(shè)計快速入門指南

　　The aim of this document is to provide an easy to follow guide as to the set up and usage of the Freescale High Power/High Brightness Lighting Reference Design （LRD）。

　　There are two versions of the LRD， a high power version capable of delivering 12A per LED with up to 4 LEDs/Channels per High Power （HP） LED Driver board. The second version of the LRD uses a 4 LED/Channel Low Power （LP）LED Driver board capable of delivering up to 1.5A per LED/Channel. The reason for these two versions is that the HP LED Driver board targets high current LEDs like those from Luminus Inc.， in particular their CBM380 product that offers red， green blue & white LEDs in one package. This package is capable of sinking a maximum of 32A. The LP LED driver board targets high brightness LEDs from a range of manufacturers ‐ Avago， Cree， Osram， Philips Lumileds and Seoul Semiconductor for example. As such the LP LED driver board has a daughter‐card arrangement so that different manufacturers LEDs can be driven with a simple re‐spin of just the LED daughter‐card.
