    摘要: Die Erfindung betrifft ein Betriebsverfahren, insbesondere ein Dimmverfahren für eine Entladungslampe. Zur Einstellung der maximalen Helligkeit wird in der Entladungslampe, beispielsweise mittels zweier Außenelektroden (5, 6), eine dielektrisch behinderte Entladung erzeugt, die unter Bildung von Xenon-Excimeren UV-Strahlung emittiert, die mittels Leuchtstoffen (2) in Licht umgewandelt wird. Um ein starkes Dimmen der Entladungslampe zu ermöglichen, wird mittels zweier Kaltkathoden (3, 4) eine UV-Strahlen emittierende Xenon-Niederdruckentladung generiert und die dielektrisch behinderte Entladung abgeschaltet. Beide Entladungstypen werden vorzugsweise mittels Hochspannungsimpulsen, die von einem Betriebsgerät (7) erzeugt werden, angeregt. Das Dimmen erfolgt vorzugsweise durch Austasten von Impulsfolgen.

    摘要: A magnetron (11) for generating electromagnetic energy in the microwave region includes an extension (14) for its antenna terminal (12). The extension (14) extends the length of the antenna (12) to control the phase of the loading on the magnetron (11). A cylindrical ground flange (16) and perforated screen (19) encloses an electrodeless lamp (15), thereby permitting microwave energy to excite the gas within the lamp (15), while confining the energy to the space bounded by the perforated screen (19) and cylindrical ground flange (16). The extension (14) for the antenna (12) has a length which maintains the reflection coefficient phase to a level which does not adversely affect the magnetron operating frequency.

    摘要: A single flash discharge tube system is pro­vided that is capable of emitting artificial light of a controlled and variable spectral output to compensate for photographic film color variations and/or extremes in scene color temperature. The flash tube contains a mixture of two or more gasses with each gas in the tube having a different ionization potential. When ionized, each gas or combustion thereof produces light having a different spectral output. The ionization of each gas is controlled by a trigger voltage applied to the flash tube in accordance with a code on a film container indicative of the color balance of film contained therein and/or sensing apparatus that determines scene color temperature.

    摘要: A low pressure gas discharge lamp is made up of a light-emitting tubular bulb (2) whose elongated dis­charge space (3) contains a discharge gas including at least a xenon gas, an internal electrode (4) sealed within the bulb and located at one end of the bulb, a band-like external electrode (7) formed on the outer surface of the bulb and extending up to the other end of the bulb in the axial direction of the bulb, and a fluorescent material (6) coated on the inner surface of the bulb. The xenon gas contained in the discharge space has a partial pressure within the range of 5 to 40 Torr.

    摘要: A rare-gas arc lamp includes a pair of coil filaments (25, 27) disposed at the opposite ends of an elongated bulb (13) for increasing an area of a positive column produced between the coil filament pairs in a direction perpendicular to the elongated axis of the bulb, and a rare-gas mainly including xenon gas sealed in the bulb at a prescribed pressure selected from the range between 20 Torr and 200 Torr for reducing the evaporation of an electron emissive material coated on the coil filament pairs during operating. The combination of the coil filament pairs and the xenon gas sealed in the bulb at a prescribed pressure selected from the range between 20 Torr and 200 Torr may reduce visible changes in a luminance distribution of the lamp which occurs when the positive column fluctuates during operating.
