ABSTRACT:
Subject invention constitutes a low-voltage limited-power (Class 2) fluorescent lighting system consisting of the following principal component parts: (a) a power-line-operated inverter power supply that provides a power-line-isolated voltage output of relatively low but substantially constant magnitude (30 Volt RMS) and relatively high frequency (30 kHz); (b) electronic means for preventing the power supply current output from exceeding a pre-determined relatively modest magnitude (8 Amp RMS); (c) a number of fluorescent lighting units, each unit consisting of one or more fluorescent lamps and a corresponding high-frequency ballasting means being adapted to be operated at a high power factor from the voltage output of said power supply; and (d) a pair of conductor wires connected with the output of said power supply and adapted to permit a number of said fluorescent lighting units to be connected in parallel across said voltage output at various points along said pair of wires. The invention provides for a high-efficiency fluorescent lighting system that consists of a number of fixtured and/or non-fixtured lighting units that can easily and safely be installed by a person of but ordinary skills; yet, even with output power limited to 100 Watt, is capable of providing a total amount of illumination that is equivalent to that provided by over ten ordinary 60 Watt incandescent lamps.
