Abstract
A lamp system including an alternating current power source for supplying a signal voltage, an input transformer having primary and secondary windings connected to the power source for increasing signal voltage, a signal rectifier connected to the secondary winding for creating a direct current signal from the increased signal voltage, a signal oscillator connected to the signal rectifier for creating a high-frequency signal from the direct current signal, one or more ballasts connected to the signal oscillator to create high-voltage high-frequency signals from the direct current signal, one or more lamps driven by the high-voltage high-frequency signal from the ballasts, a sense winding on an output side of each of the ballasts for inducing alternating current signals, an apparatus for receiving and processing the alternating current signals, and an apparatus for displaying the processed alternating current signals.
