Embodiment Construction

[0020] figure 1 The electric lamp in the invention has a light-transmitting bulb 1, and an electrical element 2, namely a pair of electrodes, is arranged in the bulb. The counter electrode is surrounded in the figure by an inner envelope 3 filled with an ionizable gas such as neon / argon and sodium vapour. The supply conductors 4 , 5 extend to the electrical component 2 . A lamp cap 6 having a housing part 7 and a base part 8 supporting an electrical contact part 9 is connected to the bulb 1 . The electrical contact part 9 has a surface via which the current supply conductors 4 , 5 lead to the outside and on which they are fixed.

[0021] In this figure, the base part 8 of the lamp cap 6 has two contact parts 9 (see also figure 2 ), each consisting of a flat, oval brass plate. The lamp cap 6 shown is a conventional lamp cap with a B-22 clip and conventional contact members 9 . The current supply conductors 4 , 5 shown are made of copper in the region of the contact part 9...

Abstract

An electric lamp with a simple welding / brazing connection comprises an electric element (2) in a translucent lamp vessel (1) with current supply conductors (4, 5) and a lamp cap (6) connected to the vessel (1) and having a shell portion (7) and a base portion (8) carrying an electric contact (9). The current supply conductor (4, 5) passes through the surface of this contact (9) to the exterior and is welded / brazed to it by means of a solidified connection body (10) of aluminum with a dope of silicon in an amount ranging from 5 to 16 % weight.

Description

technical field [0001] The invention relates to an electric lamp comprising: [0002] a transparent light bulb; [0003] - electrical components inside the bulb; [0004] supply conductors extending to electrical components; [0005] A lamp cap connected to a light bulb, the lamp cap having a housing portion and a base portion, each of the housing and the base supporting an electrical contact member, each electrical contact member having a surface, each current conductor passing through comprising a majority of aluminum and A cured bond of additives is secured to the surface. Background technique [0006] Such an electric lamp is known, for example, from European patent EP-406 948 B1. [0007] The known electric lamp has a lamp base with a conventional flat plate, which is fixed to the base part as a contact element, via which the current supply conductor leads to the outside. In the known electric lamp, the connecting body is a drop of aluminum ...
