Abstract: Apparatus for exciting an electrodeless lamp to produce visible light. A source of microwave energy (22) is coupled to a cylindrical cavity (10) which encloses an electrodeless lamp (11). The cylindrical cavity (10) includes a sidewall and end wall (10a) which is made from a metallic mesh which passes light produced from the electrodeless lamp (11). The electric field intensity within the cylindrical cavity (10) is increased in the region (11a) above the lamp center (11b). The increased electric field intensity produces more uniform temperature across the bulb surface, thereby increasing the rate of plasma heating of gas molecules within the lamp (11).

Abstract: This invention pertains to an apparatus for coupling electromagnetic energy to electrodeless lamps. A waveguide (20) having one end connected to a source of electromagnetic radiation (23) was closed at the second opposite end (18). A coupling device at the second end (18) couples microwave energy from the waveguide (20) to an electrodeless lamp (11). The coupling device includes a coaxial transmission line (12) having a center conductor (15) extending through one of the walls of the waveguide (20) adjacent the second end (18). An alcove partition (27) within the waveguide (20) contacts the extending conductor (15) and forms an alcove (19) in the waveguide (20). The alcove portion (19) provides for an impedance matching structure between the transmission line (12) and waveguide (20). The electrodeless lamp (11) which is positioned above the free end of the coaxial transmission line (12) is excited with the coupled microwave energy.

Abstract: An inductively coupled electrodeless lamp has a pair of excitation coils positioned exterior to an envelope or bulb. The pair of excitation coils are positioned and driven in a manner to produce at least one moving ring-shaped electric field within the envelope. The moving ring electric field results in formation of a correspondingly moving ring of plasma discharge within the envelope. The movement of the electric field results in a more uniformly hot plasma discharge volume within the envelope, thereby facilitating emission or re-radiation of photons. The movement of the ring-shaped electric field (and the corresponding plasma discharge) can be rotational, oscillating, wobbling, or switching. The nature of the movement depends upon such factors as coil geometry and orientation and coil excitation (driving) technique. In some embodiments, the pair of excitation coils are driven by quadrature techniques (e.g., either phase quadrature, frequency quadrature, or amplitude quadrature). Differing coil geometries and orientations are taught.

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: An electrodeless lamp includes a stationary bulb (10) containing a fill for producing a discharge, the fill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field (E, E1) such as, for example, a circular polarized electric field.

Abstract: Aparato para excitar una lámpara sin electrodo para producir luz visible. Una fuente de energía de microondas (22) se acopla a una cavidad cilíndrica (10) la cual encierra una lámpara sin electrodo (11). La cavidad cilíndrica (10) incluye una pared lateral y pared de extremo (10a) la cual es hecha a partir de una malla metálica la cual pasa luz producida desde la lámpara sin electrodo (11). La intensidad del campo eléctrico dentro de la cavidad cilíndrica (10) es incrementada en la region (11a) sobre el centro de la lámpara (11b). La intensidad del campo eléctrico incrementada produce temperatura más uniforme entre la superficie del bulbo, por lo que incrementa la velocidad de calentamiento del plasma de las moléculas de gas dentro de la lámpara (11).

Abstract: Apparatus for exciting electrodeless lamps. A magnetron for generating electromagnetic energy in the microwave region includes an extension for its antenna terminal. The extension extends the length of the antenna to control the phase of loading on the magnetron. A circular ground flange and perforated screen enclose the electrodeless lamp, permitting microwave energy to excite the gas within the lamp, while confining the energy to the space bounded by the perforated screen and cylindrical ground flange. The extension for the antenna has a length which maintains the reflection coefficient phase to a level which does not adversely disturb the magnetron operating frequency.
