摘要： An electrodeless discharge lamp comprising an arc tube constructed of a light-transmissive material. An exciting structure surrounds the arc tube and is energizable with radio frequency current to develop an arc discharge. A reflective coating of non-conducting insulating material is disposed on the arc tube wall and is located to reflect light from the arc discharge through the arc tube. The reflective coating and the uncoated portion of the arc tube wall are surrounded by the exciting structure so that light from the arc discharge may reach the reflective coating without blockage by the exciting structure and, following reflection by the coating, travel through the uncoated portion of the arc tube wall.

摘要： An arc stabilization arrangement for a discharge lamp having a light transmissive arc tube containing a fill of gas excitable to a discharge state upon introduction thereto of a drive signal having a predetermined frequency associated therewith, includes a modulating arrangement effective for providing a modulating signal which is imposed onto the drive signal. The modulating signal has a frequency associated therewith which approximates the acoustic resonance of the gases within the fill, such modulating signal frequency being less than the frequency of the drive signal. In one embodiment of the invention the modulating arrangement is an amplitude modulating scheme effective such that a modulating amplitude of greater than about 5% of the amplitude of the drive signal is achieved. In yet a further implementation of the present invention, the frequency of the modulating signal is swept about a range of frequencies so that a varying acoustic resonance frequency can be encompassed by the modulating signal.

摘要： High pressure xenon is used as a buffer gas in place of mercury in a high pressure sodium iodide arc discharge lamp. Xenon buffer gas has a more favorable influence than mercury on the sodium D-line spectrum and does not react with halides in the lamp fill. The use of xenon buffer gas increases the efficacy of the high pressure sodium iodide arc lamp.

摘要： Individual coolant passages in the airfoil portion of a liquid-cooled turbine bucket are each provided with a plurality of inwardly protruding circumferentially-extending crimps or rings located at spaced intervals along each passage, each crimp, protrusion or ring extending along the inner periphery in a plane generally perpendicular to the wall of the coolant passage at that location. The main flow of liquid coolant moving in each such individual passage during turbine operation under the combined influence of centrifugal and Coriolis forces is broken up and dispersed over an enlarged area of the interior of the coolant passage upon encountering the protrusions.

摘要： An apparatus for improving the performance of a ceramic metal halide (CMH) lamp includes an interior chamber (12) disposed within an outer envelope (10). In a preferred arrangement, two legs (14, 16) extend laterally in opposite directions from the chamber. Each leg encloses an electrode/leadwire assembly (22, 24). The electrode/leadwire assembly is constructed from a single continuous piece of wire, preferably tungsten, which forms a shaft or mandrel (50). One end of the mandrel supports an electrode tip (52) which is also preferably made from tungsten. The mandrel also supports an overwind component (54) at a predetermined position. In a desired arrangement, the overwind component is made from molybdenum. The single or one-piece mandrel negates the need for a welded shank assembly resulting in a stronger and more stable lamp that is less expensive to manufacture.

摘要： An electric lamp includes a sealed outer envelope, an arctube located within the envelope, a shroud separate from the arctube having an ellipsoidally-shaped reflecting portion positioned around the arctube, and a coating disposed on the reflecting section of the shroud for reflecting light having predetermined wavelengths emitted by the arctube. The ellipsoidal shape of the shroud is effective for reflecting the light substantially back toward the arctube. Particularly when the coating is a color correcting coating, the shape of the reflecting section is tailored to maximize reflection of radiation at selected wavelengths back toward the arc of the arctube.
