Abstract
A lamp load control system that includes a lamp controller comprising an inverter generating an AC signal from a DC signal, a load coupled to the inverter, and a feedback circuit coupled to the load generating a feedback signal indicative of power supplied to the load. In one exemplary embodiment, the system also includes a command signal generator generating a command signal indicative of a preferred power output of the inverter; wherein the command signal is combined with the feedback signal to cause the controller to temporarily reduce power delivered to the load. In another exemplary embodiment, the system includes a command signal generator generating a command signal indicative of a preferred power output of said inverter; wherein the controller receives the feedback signal and the command signal and temporarily reduces power delivered to the load based on the value of the feedback signal or the command signal.
