Abstract
A plasma lamp apparatus includes a post structure with a material overlying a surface region of the post structure, which has a first end and a second end. The apparatus also has a helical coil structure configured along the post structure. The apparatus includes a bulb with a fill material capable of emitting electromagnetic radiation. A resonator coupling element configured to feed radio frequency energy to at least the helical coil causes the bulb device to emit electromagnetic radiation.

A plasma lamp apparatus comprising:
- a post structure comprising a material overlying a surface region of the post structure, the post structure having a first end and a second end;
- an output support structure provided on the first end of the post structure;
- a helical coil structure operably configured along one or more portions of the post structure;
- a bulb device comprising a first portion and a second portion spaced from the first portion, the first portion of the bulb device being configured to the output support structure provided on the first end of the post structure;
- and
- a resonator coupling element configured to feed radio frequency energy to at least the helical coil structure and to cause the bulb device to emit electromagnetic radiation.
A plasma lamp apparatus comprising:
- a support structure having a first end and a second end;
- a coil structure configured along one or more portions of the support structure;
- a bulb device configured to the first end of the support structure;
- a ground potential coupled to the second end of the support structure;
- a coupling element configured to feed at least radio frequency energy to at least the coil structure and to cause the bulb device to emit electromagnetic radiation;
- and
- a housing configured to enclose the support structure, coil structure, and coupling element, the bulb device being disposed outside the housing.
