I am developing a shield to drive high-power and high-brightness LEDs, LEDs like those in the CREE XLamp and Philips Luxeon families. I think it will really help the development of high-brightness LED products capable of replacing standard incandescent and compact fluro products.
This shield paired with a Zigbee or WiFi shield also offers some really interesting wireless lighting possibilities.
Before I finish my design and get it fabricated, I am looking for some feedback on the idea and design, and also to see if anyone else is interested in one.
The design: 1) It's based on the LED driver LM3404 from National Instruments http://www.national.com/pf/LM/LM3404.html#Overview . 2) It will operate from a 24V power supply. 3) The shield will also include a linear regulator so that the LED driver shield and Arduino can be powered by a single supply.
Questions: 1) Does anyone know of anything similar? 2) Does anyone have any feedback/suggestions for changes or additions? 3) Is anyone interested in one once manufactured? 4) Does anyone have a good idea for a name?
