Abstract: An electrodeless lamp comprises an envelope (12) containing a plasma forming fill which includes at least one of sulfur and selenium when excited which emits principally visible light, which is in the form of molecular radiation. The envelope (12) has a diameter of less than one half inch. Means (1) are provided for generating electromagnetic energy. Further means (2, 3, 4, 5, 6) are provided for coupling said electromagnetic energy to said envelope to excite said fill, which in the absence of envelope rotation or with rotation at an insufficient speed, forms a discharge (14) which does not substantially fill the interior volume of said envelope (12). By additional means (13) the envelope (12) is rotated at a fast enough rate so as to cause the discharge (15) formed by the fill to substantially fill the interior volume of the envelope (12).

Abstract: Apparatus for efficiently exciting an electrodeless lamp to produce visible light. A source of microwave energy is coupled to a cylindrical cavity which encloses an electrodeless lamp. The cylindrical cavity includes a sidewall and end wall which is made from a metallic mesh which passes light produced from the electrodeless lamp. The electric field intensity within the cylindrical cavity is increased in the region above the lamp center. The increased electric field intensity produces a more uniform temperature across the bulb service, increasing the rate of plasma heating of gas molecules in the lamp.

Abstract: A microwave lamp having a compact structure utilizing a coupling slot which is located off center in one direction and a canted bulb stem which is located off center in the opposite direction. A non-conventional waveguide is used which has about the width of a WR-284 waveguide and about the length of a WR-340 waveguide.
