SYSTEM FOR DIGITALLY CONTROLLED DIRECT DRIVE AC LED LIGHT

An AC lighting system where the intensity and/or color may be controlled by varying an output current level of a linear current regulator between a first current level and a second current level and/or varying ON times of a plurality of LED stages, respectively. When the current reaches the second current level, the output current level of the linear current regulator may be maintained at the second current level while ON times are varied is provided. Also provided is an AC lighting system where each switch may be selectively operated to provide power to a bootstrap conditioning network during the period of time when the applied voltage is insufficient to turn on the one or more LEDs corresponding to the respective switch when an LED ON time is short, such that power is provided to respective level shifted drive.
