Abstract
A ceramic arc body includes a main body having a chamber. A leg extends from the main body and has an internal opening therethrough that communicates with the chamber. An electrically non-conductive seal member is received in the leg opening. A tapered internal surface abuttingly engages the seal member and provides for centering of the seal member relative to the leg. A separate tapering region, shoulder, or stop surface limits insertion of the seal member into the leg opening for precision location of the seal member, and in another embodiment, a single continuous taper inside the leg cooperates with a tapered seal member for both centering and precision insertion of the seal member into the leg. In another embodiment, a hybrid electrode is employed where one portion of the hybrid electrode is electrically non-conductive and a second portion of the electrode is electrically conductive. The hybrid electrode mechanically supports both the lamp and the starting coil and also provides electrical connection to the starting coil.
