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.

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 ultra bright, low wattage inductively coupled electrodeless aperture lamp is powered by a solid state RF source in the range of several tens to several hundreds of watts at various frequencies in the range of 400 to 900 MHz. Numerous novel lamp circuits and components are disclosed including a wedding ring shaped coil having one axial and one radial lead, a high accuracy capacitor stack, a high thermal conductivity aperture cup and various other aperture bulb configurations, a coaxial capacitor arrangement, and an integrated coil and capacitor assembly. Numerous novel RF circuits are also disclosed including a high power oscillator circuit with reduced complexity resonant pole configuration, parallel RF power FET transistors with soft gate switching, a continuously variable frequency tuning circuit, a six port directional coupler, an impedance switching RF source, and an RF source with controlled frequency-load characteristics. Numerous novel RF control methods are disclosed including controlled adjustment of the operating frequency to find a resonant frequency and reduce reflected RF power, controlled switching of an impedance switched lamp system, active power control and active gate bias control.

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).
