An electrodeless plasma lamp is described comprising a lamp body including a solid dielectric material. The lamp includes a bulb received at least partially within an opening in the solid dielectric material and a radio frequency (RF) feed configured to provide power to the solid dielectric material. A conductive material is provided adjacent to the bulb to concentrate the power proximate the bulb. The conductive material may be located below an upper surface of the solid dielectric material. The conductive material may modify at least a portion of an electric field proximate the bulb so that the portion of the electric field is oriented substantially parallel to an upper surface of the lamp body.

What is claimed is: 1. An electrodeless plasma lamp comprising:a lamp body comprising a dielectric material having a relative permittivity greater than 2, the lamp body including a recess extending from a lower surface of the lamp body into the lamp body towards an upper surface of the lamp body;a bulb adjacent to the upper surface of the lamp body, the bulb containing a fill that forms a plasma when RF power is coupled to the fill from the lamp body;an elongate RF feed extending into the lamp body;a conductive component having a lower end and an upper end, the lower end being electrically coupled to an electrically conductive material substantially surrounding the lamp body, and the upper end being proximate the bulb;a radio frequency (RF) power source for coupling power into the lamp body through the RF feed and wherein the RF feed is spaced from and extends substantially parallel to the conductive component.
