Hi all, I have procrastinated far too long now on this project. I have managed to wire a few together and make them light up, and show them off...however I want a proper solution.
I have these 2.4-2.8VF 700Ma, Colour LED. I need to get them powered by whatever PSU I have laying around. Currently I have to work with 32V @ 925MA PS. 3 x 5V @ 700MA.
I am using this nifty calculator "LED series/parallel array wizard" on wiring LED'S in series, and it tells me what size resistor and how much power it will dissipate based on my build.
We have 13 LEDS x 2.4VF @ 700Ma. Which consumes 31.2V, since my PS is 32V...I need to drop off 0.8V. It reccomends a 1w 1.2Ohm resistor.
I also would like to limit the current to the LEDS to 650, how would I go about getting this ?
I really need some help, I am scared to just plug and play here....
