Hi all,
I want to install some microcontroller based mood lighting using high- flux Cree LEDS. Most of the interesting led drivers which can be coupled to a microcontroller for this sort of application (e.g., XP Power LDU series) are DC-DC with ~40V input*. What is the easiest way to get a suitable 40VDC input for these from the UK mains? I imagine that there must be some standard way of doing this, based upon how many such drivers there are, but my background is low-voltage embedded systems so I'm not familiar with this sort of application. Any tips would be appreciated.
thanks,
dan.
- I know that there are various dimmable LED drivers for mains application, but all but the most expensive seem to use potentiometers or phase-dimming.
