How to convert a 12V LED string designed for use with an AC/DC power converter for direct wire to a 12V DC system? Answered
I am trying to use a 12V LED light string for lighting in a bus conversion. The LED string is 12V, but comes with a AC/DC adaptor so it is intended to be plugged in to an AC outlet...however, I want to connect it directly to the bus/RV's 12V DC electrical system. I'd planned to just use a DC connector to replace the power adaptor and connect directly to the 12V circuit/wiring...but I think I need to regulate the amperage going in to the LED string. ?? I am not sure what to use to regulate the current of that circuit. I've read about LED drivers, but most seem to be AC/DC...and I want DC/DC. Also, the constant current drivers don't seem to match up to the current the light string would require if I assume the power adaptor is supplying the correct amperage. Help?
The LED light string does not state many specs, except that it is 12V / 6W and uses 100 micro/fairy LEDs. The AC/DC power adaptor that comes with it says the output is 12V/1A, therefore I assume I need to regulate the amperage to 1A...but wanted to confirm with someone more knowledgeable than me. The RV electrical system is composed of a 440AH battery bank and from what I've read about LED's I can't just wire it into a circuit fed by that much potential current, even if it's fuse protected at the DC distribution panel. Any suggestions?
