Abstract:
An arrangement comprising:a frequency-converting central power supply mounted at a first location; the central power supply (i) being powered by ordinary power line voltage provided from an electric utility power line, and (ii) having plural power output ports at each of which is supplied an approximately sinusoidal AC voltage of frequency substantially higher than that of the power line voltage; the central power supply being operative to limit the amount of power extractable from each power output port to a level so low that any passive load connected therewith would not give rise to a fire-initiation hazard; andplural lighting units; each lighting unit located some distance away from the first location and including: (i) a power input port; (ii) a gas discharge lamp; (iii) a sub-assembly connected in circuit between the gas discharge lamp and the power input port; and (iv) a power supply cord connected between the power input port and one of the power output ports.
