  • Electric lamp with seals at plastically deformed current conductors
    Patent number: 6525474
    Abstract: The electric lamp comprises a lamp vessel (1) and an electric element (4). The electric element (4) is electrically connected to the outside via a current feedthrough that comprises an outer current conductor (7). By a plastic deformation (12) of the outer current conductor (7), e.g. flattening, it is interlocked in the wall (2) of the lamp vessel (1) and the durability of the current feedthrough of the lamp against a mechanical load is improved.
