A dimming control system includes a first circuit (100) and a second circuit (400). First circuit (100) is coupled in series with the AC line source (10) and receives brighten and dim commands from a user. The brighten and dim commands are communicated to second circuit (400) by momentarily altering the AC voltage waveforms observed by second circuit (400). Second circuit (400) provides an adjustable output signal that is coupled to inverter circuitry within an electronic dimming ballast. The output signal is adjusted by the second circuit (400) in dependence on the observed AC voltage waveforms. |
