Abstract

An apparatus for automatically characterizing and configuring a light-emitting diode (LED) lighting system is provided. The apparatus includes a driver, an identification element, and an exciter. The driver is configured to provide a plurality of constant currents within a first range, a plurality of first voltages within a second range, at a plurality of maximum power levels within a third range over a power signal and a return signal, where the driver is configurable to drive the power and return signals to provide one of the plurality of constant currents, one of the first plurality of first voltages, and one of the plurality of maximum power levels to comport with operating characteristics of an LED module. The identification element is coupled to the driver, and is configured to exhibit a unique frequency response to excitation by excitation signals generated exclusively over the power and return signals at second voltages less than a lower bound of the second range. The exciter is coupled to the identification element and the driver via the power and return signals, and is configured to generate the excitation signals, and is configured to determine the one of the plurality of constant currents, the one of the plurality of first voltages, and the one of the plurality of maximum power levels based upon the unique frequency response, and is configured to configure the driver to comport with the operating characteristics.
