Abstract: An electric lamp includes a quartz-glass envelope having at least one sealed end, a thin foil including molybdenum at least partly embedded within said sealed end, a first current conductor connected to the foil extending interiorly of the envelope, and a second current conductor connected to the foil and extending exteriorly of the envelope. The re-crystallized foil exhibits a yield strength (offset=0.2%) according to ASTM F 8M-91 below 300 MPa. This can be obtained by molybdenum doped with between 0.01 and 5 wt % of rhenium or 0.01 and 2 wt % of tungsten.

Abstract: The invention relates to an electric lamp with a high lumen output and a low sensitivity to explosion, comprising a quartz-glass envelope having at least one sealed end, a thin foil comprising molybdenum at least partly embedded within said sealed end, a first current conductor connected to said foil extending interiorly of said envelope, and a second current conductor connected to said foil and extending exteriorly of said envelope, wherein the re-crystallized foil exhibits a yield strength (offset=0.2%) according to ASTM F 8M-91 below 300 MPa. This can be obtained by molybdenum doped with between 0.01 and 5 wt % of rhenium or 0.01 and 2 wt % of tungsten. The invention further relates to a lamp with a molybdenum foil which is resistant to oxidation and corrosion comprising dopes of between 0.01 and 0.1 wt % of Ce and/or Ti, or dopes of between 0.01 and 1 wt % of Al, Co, Fe, Hf, Ir, and/or Y; or dopes of between 0.01 and 5 wt % of Cr.

Abstract: The invention relates to a lamp (1) comprising a gastight vessel (2) embedding one or more feedthrough elements (7,8) electrically interconnecting an outer current conductor (9,10) and an inner current conductor (3,4) for operating said lamp. The feedthrough elements and/or the outer and inner current conductor are molybdenum alloy components containing at least one constituent from the group formed by rhenium and chromium in a quantity between 0.01 and 5% by weight; titanium in a quantity between 0.01 and 0.1% by weight; and aluminum, cobalt, gadolinium, hafnium, iridium, iron and zirconium in a quantity between 0.01 and 1% by weight of said alloy. The invention further relates to a method of manufacturing a lamp and a lamp component.
