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: A lamp without electrodes which couples strong microwave fields to a very small lamp having a diameter of approximately 1/2" or less. The lamp is operated in a mode which is independent of the height of the hollow space and which provides electrical field lines which run parallel to the height. Compared to earlier lamps, the height of the hollow space is reduced considerably so as to ensure strong coupling of the electrical field to the lamp.

Abstract: An electrodeless lamp which couples to a small bulb and obtains a relatively high light output therefrom. A cavity which comprises a compound resonant structure including vestibule and reflector portions is provided. The combination of vestibule and reflector results in a condition of resonance throughout the cavity, whereby strong fields are coupled to the small bulb and a reflector is provided for directing and enhancing light output.

Abstract: An electrodeless lamp bulb (12) is rotated at sufficient rate to obviate isolated discharges. A coaxially excited electrodeless lamp bulb (12) is rotated in such manner that different regions of the bulb are near the high field region caused by the inner coaxial conductor, thus preventing are attachment from occurring. An electrodeless lamp bulb (12) is rotated at a high speed sufficient to improve lamp efficiency and reduce cooling requirement. An electrodeless lamp bulb (12) is provided with wall of reduced thickness at the area of the bulb (12) where it is desired to condense the fill upon turning off the power, thus providing for quicker starting.
