摘要: A method according to one embodiment may include supplying power an LED array having at least a first string of LEDs and second coupled in parallel, each the strings includes two LEDs. The this also comparing feedback signal from is proportional current said controlling voltage drop adjust relative LEDs, based on, part, signals. Of course, many alternatives, variations, modifications are possible without departing embodiment.
