Abstract: Electric lamp with a base at one end, having an inner vessel surrounded by an outer jacket, a base with electric connections supporting the inner vessel and the outer jacket, having the following features: a) the base has a base insulator with a central opening with a surrounding collar in which the inner vessel is held without cement; b) the base insulator has a circular, radially projecting segment with an associated upper and lower plateau with reference to the base; c) the outer jacket has a circular opening on the base side with a radially projecting edge that has an upper and lower contact surface with reference to the base, the lower contact surface of the edge being compatible with the upper plateau of the circular, radially projecting segment at the base insulator; and d) the outer jacket is fastened on the base by a cementless mechanical holding mechanism.

Abstract: The elongate bulb (1) of the lamp, which defines a longitudinal axis (A), is closed at opposite ends by sealing parts (6; 32), with in each case one cap being fitted at one end, the cap having an electrical contact element (13; 25) which is connected in an electrically conductive manner to a supply conductor (15; 21) leading to a luminous means, the contact element being accommodated in a tubular extension (11; 22) of the sealing part; the contact element (13; 25) has an attachment part (14; 24) which is directed inward toward the lamp interior and is equipped with at least two barbs (20; 26) which are in contact with the tubular extension (11; 21).

Abstract: The lamp comprises a discharge vessel (2) which is closed off in a vacuum-tight manner and is arranged in an outer bulb (12), a getter material being held on a support body inside the outer bulb (12). The support body is a support strip (31) to which the getter material is applied, the support strip being bent in such a way that it is automatically held in the outer bulb (12) without the need for any auxiliary means.

Abstract: The process comprises the provision of a discharge vessel (2) which is closed off on one side, fitting a second tube over part of the discharge vessel and evacuating and filling the volume of the outer bulb via a pumping hole, which remains open in the second extension part within the second tube. This pumping hole is only closed at the end by means of an operation which closes it by rolling.
