ABSTRACT:
An electrodeless lamp is excited in a termination fixture by high frequency power, the lamp being located within the fixture at the end of an inner conductor whose end is shaped such as to inhibit the arc of the lamp from attaching to the lamp envelope. In one embodiment, the inner conductor end is shaped as a hollow helical coil which generates an axial and azimuthal electric field component to create a torodial arc within the lamp. In another embodiment the inner conductor end is cup-shaped to provide a field shielding effect which distributes the field strength more uniformly across the end of the inner conductor.
