Abstract:
1. A system for controlling a light having a plurality of fluorescent tubes, each fluorescent tube having a pair of filaments, the system comprising: a plurality of transformers located in the light, each transformer having a primary winding and a secondary winding coupled between the filaments of a corresponding one of the fluorescent tubes at first terminals thereof; a plurality of sensors, each sensor connected to detect signal information indicative of a signal between the filaments of a corresponding one of the fluorescent tubes; one or more AC signal generators located remotely from the light, the one or more AC signal generators capable of generating a plurality of low voltage AC signals, each low voltage AC signal associated with a corresponding one of the fluorescent tubes; a plurality of low voltage AC links, each low voltage AC link connected to conduct a corresponding low voltage AC signal between the one or more AC signal generators and the primary winding of a corresponding transformer of a corresponding one of the fluorescent tubes; and a controller located remotely from the light, the controller connected to receive signal information from the plurality of sensors and the controller configured, on the basis of the signal information, to independently control one or more characteristics of each of the low voltage AC signals.
