Abstract: A tungsten alloy feedthrough for ceramic discharge vessels is used to form a hermetic seal with the ceramic body of the discharge vessel. The tungsten alloy comprises tungsten alloyed with a metal selected from titanium, vanadium or a combination thereof. The alloy may be formulated to have a coefficient of thermal expansion that closely matches that of the ceramic to prevent cracking. Preferably, the tungsten alloy contains from about 10 to about 35 wt. % of a metal selected from Ti, V, or a combination thereof.

Abstract: The present invention is a ceramic discharge vessel for use in high-intensity-discharge (HID) lamps. The discharge vessel has a ceramic body and at least one seal region comprised of an aluminum oxynitride material. The seal region further has a surface layer for contacting a frit material wherein the surface layer is less reactive than the aluminum oxynitride material with respect to the molten frit during sealing. Preferably, the surface layer has a lower nitrogen content than the aluminum oxynitride material. The less reactive surface acts to minimize the formation of bubbles in the sealing frit during the sealing operation.

Abstract: A method for manufacturing a high-pressure discharge lamp includes a process step in which a sealing portion is formed out of a side tube portion of a glass pipe that is designed for use in a discharge lamp. In the step of forming the sealing portion, a compound glass tube, which is composed of an outer tube made of a first glass and an inner tube made of a second glass whose softening point is lower than that of the first glass, is inserted into the side tube portion, which is also formed of the first glass. The side tube portion is then heated so that the side tube portion is brought in tight contact with the compound glass tube. Thereafter, at least the sealing portion is heated at a temperature higher than the strain point temperature of the second glass portion.

Abstract: A discharge lamp of the short arc type in which a lead pin, located within a hermetically sealed tube, is prevented from being irradiated with light. Such a construction prevents the lead pin from undergoing a temperature rise thereby preventing the destruction of the hermetically sealed tube. The discharge lamp of the short arc type includes an arc tube adjoined laterally by hermetically sealed tubes through which a lead pin, which supports an electrode, is routed. The hermetically sealed tubes are sealed by graded glass on the lead pins, and the lead pin is prevented from being irradiated with light by providing the outside surface of the hermetically sealed tube, at least in part, with a high emissivity material and then providing a reflectivity material on the exterior surface of the emissivity material.

Abstract: A discharge lamp (10) is disclosed with a closed discharge vessel (20) which is surrounded by a wall of transparent material. Two electrodes (30) are present, partly embedded in the wall and projecting into the interior of the discharge vessel (20). At least one, but preferably both electrodes (13) are elongate in shape and comprise a head part (50) and a shaft part (40), which are distinguished by different diameters and/or different materials. Tungsten is preferred for the head part (50) and a tungsten-rhenium alloy for the shaft part (40). The shaft part (40) is enclosed in the wall material, usually quartz, whereas of the head part (50) only a first, short portion (50a) is in contact with the wall, while its second, longer portion (50b) projects into the interior of the discharge vessel (20). Favorable diameters for the head part (50) were found to be 350 to 450 μm, and for the shaft part (40) 150 to 400 μm. A long lamp life is achieved with the electrode design according to the invention, in particular in thermally strongly loaded discharge lamps as preferred for automotive applications. There are additional advantages in a lesser crystallization of the discharge vessel (20), less burning-off of the electrodes (30), and an improved run-up behavior.
