Abstract
A lighting unit includes a lighting source and a lighting driver connected to the lighting source. The lighting driver is connected to a line voltage having a burst of signaling transitions that transition between a nominal line voltage and a signaling voltage. The lighting driver detects the signaling transitions on the line voltage, generates a dimming signal responsive to the detected signaling transitions, provides a driving current to the lighting source, and adjusts a level of the driving current responsive to the dimming signal.
