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. 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.
