Patent abstract
A dielectric waveguide integrated plasma lamp (DWIPL) with a body consisting essentially of at least one dielectric material having a dielectric constant greater than approximately 2, and having a shape and dimensions such that the body resonates in at least one resonant mode when microwave energy of an appropriate frequency is coupled into the body. A bulb positioned in at least one lamp chamber in the body contains a gas-fill which when receiving energy from the resonating body forms a light-emitting plasma.
