Abstract: A method and a system for providing electrical power to several gas discharge tubes, include a master power supply and several high-voltage modules. The master power supply is constructed and arranged to provide high-frequency and low-voltage power to the high-voltage modules. Each high-voltage module, in turn, provides high-frequency and high-voltage power to a gas discharge tube. The high-voltage modules include step-up transformers with their primary side connected in series to the output of the master power supply and their secondary sides connected to the gas discharge tubes.

Abstract: A high-frequency power supply system for a plurality of fluorescent tubes includes an inverter type power supply connected to the primary side of the high-voltage transformer. The secondary side of the high-voltage transformer includes two high-voltage coils arranged to provide power to four hot cathode fluorescent tubes, wherein each of said high-voltage coils is connected to two of said hot cathode fluorescent tubes connected in parallel. The secondary side of the high-voltage transformer also includes supplemental coils arranged to heat filaments of the hot cathode fluorescent tubes. The power supply also includes at least one capacitor and at least one inductor connected to the secondary side and arranged in a manner that the secondary side provides power to a substantially resistive load.

Abstract: An electrical power system for a cold cathode tube includes a high-voltage transformer with a primary side connected to a power supply and a secondary side connected to a cold cathode tube and includes a ground fault detector. The ground fault detector includes a resistive path, a detection circuit, an isolation circuit, and a stop latch. The resistive path is connected to the secondary side of the high-voltage transformer and is arranged to provide a ground fault path to ground fault current. The detection circuit is connected to the resistive path and is constructed and arranged to provide an output representing a fault detection signal. The isolation circuit is connected to the detection circuit and is constructed and arranged to isolate the fault detection signal from the primary side of the high voltage transformer.

Abstract: A universal mounting structure has receptacles for connection to a cold cathode tube. The structure has a mounting bracket which may be rotated about a longitudinal access of a receptacle housing, thus allowing mounting in any of a plurality of different configurations. The receptacle may include an electrical threaded connecter for an input signal to be received, the electrical threaded connector being aligned with the longitudinal access of the receptacle housing and providing a physical connection by which a mounting bracket may secure the receptacle housing to a mounting wall. The electrical threaded connector can also be used as a single attachment point for the receptacle. In another embodiment, the housing itself includes a flange extending from a plurality of faces of the housing to facilitate different mounting configurations.
