Abstract
A system and method for controlling a light output from a LED-based lighting solution is provided that may receive phase-cut AC signals and/or external digital control signals. The invention is capable of receiving both a phase-cut AC signal and an external digital control signal simultaneously and providing a desired light output from a LED-based lighting solution. The system generally includes a power source electronically connected to one or more dimmers and an AC power output of the dimmer connected to a solid state lighting device such as an LED. The system is capable of receiving signals from a wired and/or wireless external digital control device to additionally control the desired light output from a LED-based lighting solution.
