STARTING ELECTRODES FOR SOLENOIDAL ELECTRIC FIELD DISCHARGE LAMPS

摘要

Efficient starting of solenoidal electric gas discharge lamp is effected when a primary voltage exceeds a critical transition level. A starting potential may be applied to electrodes on the external surface of the lamps which are capacitively coupled to a fill gas. Alternatively, the electrodes may be disposed within the lamp envelope. Optimally, the starting electrodes are disposed along the axis of an annular transformer core at opposite ends of a core tunnel region.
