摘要： A discharge tube for a high pressure metal vapor discharge lamp is disclosed, which comprises a translucent alumina tubular body, first and second end plates of cermet having a firing shrinkage factor which is less than that of the translucent alumina tubular body, end first and second electrode support members partially embedded in inner sides of the first and second end plates, respectively. The first end plate is fitted to the first end portion of the alumina tubular body and bonded thereto through shrinkage fitting at a shrinkage fitting ratio of the tubular body to the first end plate being from 3 to 6% during a simultaneous sintering of the first end plate to the tubular body and a simultaneous bonding of the first electrode support member to the first end plate through shrinkage fitting at a shrinkage fitting ratio of the first end plate to the first electrode support member being from 4 to 16% when the alumina tubular body is fired to be translucent. The second end plate is fitted to the second opposite end portion of the tubular body and is bonded thereto by means of a frit. When the discharge lamp is in use, the second opposite end portion is located at a vertically higher position than the first opposite end portion. A method of producing such discharge tubes is also disclosed.

摘要： A ceramic envelope device for use in a HID (high intensity discharge) lamp, which includes: (a) a translucent ceramic tube; (b) a pair of electrically conductive end caps which close longitudinally opposite ends of the ceramic tube; (c) a pair of oppositely located discharge electrodes each of which is supported at a first end thereof by a corresponding one of the end caps such that a second end of each electrode protrudes from an inner surface of the corresponding end cap in a longitudinally inward direction in the ceramic tube; (d) an electrical insulator provided for one or both of the pair of end caps; and (e) a sealing member disposed to maintain fluid-tightness between an engaging portion of the end cap for which the electrical insulator is provided, and the corresponding end of the ceramic tube. The electrical insulator includes a peripheral portion which covers a peripheral portion of the inner surface of the corresponding end cap, and the end of the ceramic tube sealed by the sealing member includes a contact portion which contacts the peripheral portion of the electrical insulator, to thereby isolate the sealing member from an inner space in which the second end of each discharge electrode extends.

The first and second axial portions define an annular shoulder surface radially inwardly extending between the first and second inside diameters. The first axial portion preferably has a cylindrical wall thickness of 1.0-1.5 mm, and the annular shoulder surface preferably has a radial width of 0.2-0.8 mm. The sealing layer is interposed between the first axial portion of the arc tube and the corresponding end cap.
