ABSTRACT:
A low-voltage, high-efficiency signage system comprises a housing having a translucent indicia bearing panel member. A gas discharge lighting device inside the housing is driven from a source of a low-voltage, high-frequency square wave voltage source having a pair of output terminals. A coupling circuit which is not resonant at the high frequency connects the low-voltage, high-frequency square wave voltage to the gas discharge lighting device to non-thermionically start and operate the gas discharge lighting device, and thereby illuminate the translucent indicia bearing member from inside said housing. The low voltage is from about 2 volts to about 90 volts and the frequency is from about 75 kHz to about 3.5 MHz.
