Abstract
An electrodeless lamp which couples strong microwave fields to a very small bulb of diameter about 1/2' or smaller. The lamp is operated in a mode which is independent of the height of the cavity and which provides electric field lines parallel to such height. The height of the cavity is substantially reduced as compared with prior lamps to provide strong coupling of the electric field to the bulb.
