So, this is my first question here in this forum and I don't know if I'm doing this right. Then in fisrt place, I'd like to apologize myself if I'm doing something wrong or if my english is a little ununderstandable. I also don't know much about electronics, but even so I want to do this project and because of that I'd be extremely grateful if someone could help me.
What I'm trying to do is a 16x16 (= 256) led panel with 5W leds that need a 700 mA current each. The leds have differents wavelenght and beacuse of that, I want to divide these leds in two differents groups so that I can control the brightness of each group independently with its correspondent dimmer. The main point is, I want that when the dimmers allows the maximal current flows, each led must bright with the full intensity.
So, having said that, I'd like to ask 3 questions:
Would I need to use something else than a heatsink, transformer, the leds, and the dimmers to do this? (of course things like wires and plugs are already implicit).
Wich transformer suld I use ?
How should I set those things to not lose any brightness intensity of each led ?
