Hi guys, I´m trying to use a generic RGB controller (like this: http://www.aliexpress.com/item/Free...-Tapes-Bar-Light-DC12-24V-144W/916218297.html) to make a battery powered device with some CREE power LEDs I have. I´m using 3 simple current limiters in pararel (similar to this: http://www.instructables.com/id/Power-LED-s---simplest-light-with-constant-current/#step1 - one for each LED), in order to keep them runing at 350mA each, since the RGB controller doesn´t limit current, and 450mA is the larger current my battery can handle for this project (It´s a 6V, 4.5A). Here´s the problem: When I light the white color (R+G+B), the controller doesn´t balance each LED so that the total current stays near 350mA. Instead, all the 3 LEDs light at It´s maximum, and the device goes to 1.05A. My question: Is there any (simple) way to use 350mA for any color configuration (or at least for R, G, B and W)? I tryed to imagine a simple circuit with relays, or transistors as a swich and a fourth current limiter for the 3 LEDS together, but could not get anywhere. Any help is apreciated.
