ABSTRACT:
An electrodeless lamp bulb of modified shape for providing more uniform emission of radiation. In the preferred embodiment the bulb is primarily in the shape of a sphere, but has at least a non-spherical portion comprised of diametrically opposed relatively flattened portions.
A microwave generated electrodeless lamp which incorporates the improved bulb provides more spatially uniform radiation at an illumination plane.
