The constant current waveform will just be a PWM waveform. If I were setting this up, I'd use a current limiting resistor to protect the diodes and use the standard PWM signal to dim them. That may be obvious as I always design these things with myself in mind as the first customer. I don't know what a buck puck is but I assure you the only thing you need to run LEDs other than this box is a current limiting resistor setup so that the maximum current allowed through the circuit is <= the max through the LEDs.

If the constant current works then we could eliminate the buck pucks/drivers from our LED ligts and save a few percentage points if efficiency. And make building your own lights, or upgrading lights, mucho easier.
