Abstract
A method of operating an LED lighting device includes sampling a voltage of a rectified AC waveform used to provide power to the LED lighting device, selectively connecting one or more of a plurality of LED light sources in a one or more of a series and parallel combination to achieve a predetermined voltage across the connected LED light sources with respect to the sampled voltage, and regulating a current through the connected LED light sources to achieve a predetermined current with respect to the sampled voltage.
