RELAMPING CIRCUIT FOR FLUORESCENT BALLASTS

摘要

A system and method of controlling a lighting system is provided. Lamp insertion detectors are coupled to a ballast and detect when relamping occurs. The outputs of the lamp insertion detectors are coupled together to provide a single input of a timing circuit. The timing circuit generates an output having a predetermined duration. This timing circuit output is received by a ballast driver circuit, which causes the ballast to provide a high voltage to a lamp socket for a predetermined duration of the timing circuit output to ignite the new lamp.
