ABSTRACT:
Subject power-limited lighting system consists of the following principal component parts: (a) a number of power-line-operated power supplies, each such power supply having a plurality of individual output receptacles, with each output receptacle being limited in terms of maximum voltage, current and power in such a way as to be classified as a Class-3 circuit according to the National Electrical Code; (b) for each power supply, a plurality of lighting units, each such lighting unit comprising one or more lamps (H.I.D., fluorescent and/or incandescent) and corresponding matching networks operative to derive the requisite lamp operating voltages and currents from one of the power supply's voltage/current/power-limited output receptacles; (c) a plurality of pairs of conductor wires adapted to provide for easy plug-in connection between each of the individual power-limited output receptacles of said power supplies and each individual lighting unit--generally with one such lighting unit being connected with each of said output receptacles. With the disclosed lighting system, the individual lighting units and the corresponding wiring means can safely and easily be installed and/or removed by persons of but ordinary skills.
