Hello,
I have made a special LED light. it has 176 3W LEDs. Each one needs to be driven at 3.3 volts and 350ma. I would prefer to keep it under 50volt input but cannot find a reasonable power supply that's not physically too big. Any recommendations? Otherwise. My most reasonable circuit design would be to run on 120vac with a series-parallel config. My questions are, is this safe? If the LED pins are exposed, can you get a shock from them, or will all the exposed pins be at the 3.3ish volts? will the first and last pins in series be any different than any others? I can protect the high volt connections and components including the bridge rectifier but not the LEDs. Any insight will be appreciated and just need to know about this. everything else I have already designed.
thanks, in advanced!
PS here is link to LED circuit layout for 120 volt. Its just the LEDs and resisters.
