Patent ID: 8203272

Claim:
An electrodeless plasma lamp comprising: a structure configured to at least partially to confine power at an operating frequency within a volume of the structure, the structure having an outer surface that is non-transmissive to light and an opening provided in the outer surface of the structure; a bulb containing a fill and having at least one transparent elongate side, a volume of the bulb being less than the volume of the structure and the opening including at least one dimension greater than a width of the bulb; a feed connectable to a power source and extending into the volume of the structure to provide the power at the operating frequency, the fill forming a plasma to emit light when the power is received by the fill; and a dielectric material supporting the bulb proximate the opening such that the light is transmitted through the transparent elongate side of the bulb when the plasma is formed along a transmission path outside of the bulb that transmits the light away from the structure.
