  • Electric lamp with H-shaped pinched seal
    Patent number: 5528106
    Abstract: The electric lamp has a lamp vessel (1) provided with a pinch seal (4) which is H-shaped in cross sections. Metal foils (6), to which inner (8) and outer conductors (7) are connected to constitute current supply conductors (5), are embedded in the pinch seal (4). The metal foils (6) are each located in a respective plane parallel to the axis (3) of the lamp vessel (1) in a respective leg (4') of the H. This allows for a relatively large distance between the current supply conductors, although the pinch seal may have relatively small outer dimensions.
