Well, considering the power will be for UV LEDs, I'm guessing that I don't want the voltage to fluctuate too much. Each LED has a Forward voltage of 3.3V and draws 20 mA. Each series will have 14 LEDs plus the 100Ω resistor. Then I'll be putting several of the 14 LED series units together in parallel. If I do 16 modules of the LEDs, the current draw is currently showing as 320mA with total power dissipation of 15.424W. 14 modules is 280mA and 13.496W dissipation.
Any idea how regulated/filtered/smoothed power really should be for LEDs? Once I get the arrays built, figure out my power distribution method (some form of a bus bar is what I'd like to make the array board pluggable), there will be a timer in the circuit for users to set their desired exposure time (I'd like to eventually make this a digital timer, but that will come later).
