Abstract
An improved lamphousing having a magnetically stabilized arc lamp. The arc lamp, such as a high-pressure short-arc xenon lamp, is mounted within the lamphousing such that the arc is positioned at the focal point of a reflector formed from a paramagnetic material. One or more permanent magnets are mounted on the exterior of the reflector to establish a magnetic flux within the reflector which stabilizes the plasma flame sufficiently to permit horizontal operation of the arc lamp at any current levels especially below the rated level for that arc lamp.
Claims5
In a lamphousing, an improved light source comprising an arc lamp having horizontally oriented electrodes, a thin-walled light reflector formed from a paramagnetic material, said reflector having an exterior surface and an interior light reflecting surface for reflecting light emitted from said arc lamp, at least one permanent magnet, and means attaching said magnet at a predetermined point and with a predetermined pole orientation to said exterior reflector surface as to magnetize a portion of said reflector to establish a magnetic field within said reflector which stabilizes the arc in said arc lamp.
