Abstract
A frequency-converting power supply is mounted on a power plug operable to be plugged into and held by an ordinary household electric power receptacle. Through an inductive internal impedance, the power supply provides a 20-40 kHz output voltage to a pair of output terminals that connect, by way of a female plug at the end of a light-weight power cord, with the input terminals of a fluorescent lamp assembly; across which input terminals is connected a capacitor of such capacitance value as to resonate with the power supply's inductive internal impedance, thereby providing the required lamp starting voltage and operating current. Also across the input terminals is connected a series-combination of a first instant-start fluorescent lamp and a special (normally shorted) female receptacle adapted to receive and disconnectably hold a special male plug; which, in turn, is connected with the terminals of a second instant-start fluorescent lamp. Thus, by way of disconnectable plug-receptacle means, one, two or more instant-start fluorescent lamps may be series-connected and properly started and operated from the frequency-converting plug-in power supply.
