I have put together a circuit with a power supply of 3.3VDC 2.5A. I have used 18AWG to feed each of the six branch circuits. Each branch circuit is wired with 24 AWG with variable numbers of 5mm led's wired in parallel with forward voltage between 3.2 and 3.7 and operating at 20ma DC.
I would like to know what problems I might run into with this setup. What i am wiring requires that I use limited amount of space and more complicated design was impractical. Parallel wiring with set voltage was ideal for my application however i was wondering if i am asking for trouble with this many leds. The power supply has over current protection and is self switching/adjusting designed for input anywhere between 90VAC to 240VAC >5sec at max with a continuous 3.3vdc output. My question is: if I have a source voltage that is an ideal nominal for my led application with enough current what are the concerns if any to the integrity of my design. In my diagram the resistor symbol represents the diodes in each branch circuit. Please excuse the error. I am using EDRAW. Any suggestions would be great. Thanks.
