ABSTRACT:
This ballast system for a gaseous discharge lamp comprises a reactor coil and core structure forming a magnetic circuit for flux developed by power-frequency current through the coil during lamp operation. The core comprises a leg surrounded by the reactor coil, two yokes at opposite ends of the leg, and flux-return structure connected between the two yokes radially outside the coil. For developing a high-voltage, high-frequency pulse for initiating lamp operation, there is provided an ignitor coil surrounding the flux-return structure and the reactor coil and inductively coupled to the reactor coil with respect to high-frequency pulse components.
