Abstract: Method of manufacturing a lamp comprising a transparent vessel containing a gas filling, a luminous element or an electrode extending inside the vessel and connected to a lead wire extending through a pinched portion of the vessel, which lead wire is provided with a protective coating obtained by applying a liquid to the outside of the pinched portion where the lead wire extends from said pinched portion, characterized in that said liquid is a solution of a compound comprising a positive ion of a material chosen for its propensity to react with oxidized lead wire material so as to form the protective coating.

Abstract: A lamp, such as a incandescant filament (halogen) or a discharge lamp, comprising a lamp vessel (1) of quartz glass and having a room filled with gas, two electrodes (5) extending into said room, two external current conductors (6) partially extending outside said vessel (1), two metal foils (4) embedded in said quartz glass, wherein a first end portion of a metal foil (4) is connected to an electrode (5) and wherein a second end portion of a metal foil (4) is connected to an external current conductor (6), and wherein an end portion (8) of said external conductor (6) which is connected to said metal foil (4) has a substantially circular cross section having a surface area which is smaller than the cross section of the portion of said external current conductor (6) extending outside the vessel (1).

Abstract: The electric lamp (1) has a lamp vessel (2), wherein an electric element (3) is accommodated. Said element is connected to current conductors (4), molybdenum portions (5) and (21) which have a coating of material chosen from the group consisting of chromium-manganese, chromium-cobalt, chromium-iron and chromium-boron alloys as a protection against oxidation.
