Abstract

A FLUORESCENT LAMP SYSTEM IN WHICH AN INDUCTOR (12) IS CONNECTED IN SERIES WITH THE CATHODES (4), 6) OF A GAS DISCHARGE TUBE (2). SEPARATE CONNECTIONS (14, 16) ARE TAPPED FROM THE INDUCTOR (12) AND ALSO COUPLED TO THE CATHODES OF THE TUBE. ONE CONNECTION INCLUDES A CAPACITOR (18). UPON CONNECTION OF AN AC ELECTRICAL SUPPLY A VOLTAGE BUILDS UP AND DISCHARGES FROM THE CAPACITOR (18) AT ONE CATHODE (4) AS A SURGE VOLTAGE BUILDS UP AT THE OTHER CATHODE (6). THE RESULTING PEAK VOLTAGE AT THE CATHODES IS SUFFICIENT TO IMMEDIATELY STRIKE AN ARC IN THE TUBE (2).(FIG. 1)
