| Title: |
Plasma Lamp Having Tunable Frequency Dielectric Waveguide with Stabilized Permittivity |
| Abstract: |
An electrodeless plasma lamp and method of generating light are
described. The lamp may comprise a lamp body, a source of radio frequency
(RF) power and a bulb. The lamp body may comprise a solid dielectric
material and at least one conductive element within the solid dielectric
material. The source of RF power is configured to provide RF power and an
RF feed configured to radiate the RF power from the RF source into the
lamp body. One or more tuning mechanisms allow tuning of the lamp body to
a given resonant frequency. The bulb is positioned proximate the lamp
body and contains a fill that forms a plasma when the RF power is coupled
to the fill from the lamp body. The at least one conductive element is
configured to concentrate an electric field proximate the bulb.
