Incandescent ballast assembly

摘要

Apparatus for use with a fluorescent lamp having a longitudinal axis and a filament winding at each end includes a pair of terminals formed for connection to a potential source with means for connecting one of the terminals to a filament winding, an incandescent lamp coupling the other terminal to the filament winding at the other end of the fluorescent lamp, a starting aid extending along the longitudinal axis of the fluorescent lamp and an impedance coupling the starting aid to the junction of the incandescent lamp and a filament winding of the fluorescent lamp.
