Abstract
A plasma lamp for an electrodeless plasma lamp having a waveguide body with an effective dielectric constant of at least 2. A drive probe is coupled to the waveguide body to provide the primary power for ignition and steady state operation of the lamp. A phase shifter is used to adjust the phase of the power provided to the drive probe between ignition and steady state operation. The phase shifter may also be used to adjust brightness during steady state operation.
