  • Patent number: 6764328
    Abstract: The electric lamp has a lamp vessel (1) composed of a glass bulb (2) and a glass plate (3) sealing the bulb (2). A shaped metal body (20) is embedded in the glass plate (3). The shaped metal body (20) has a plate-shaped metal member (10) with which a tube (11) is integral and with which current conductors (12) are integral via bridges (15). The glass plate (3) has at least one recess (4) in which a bridge (15) to a current conductor (12) is located, which bridge (15) has a disconnection (16) in the recess (4), thus insulating the relevant current conductor (12) from the metal member (10). The lamp is of a simple construction that can be easily realized. The current conductors (12) occupy a predetermined position with respect to one another in the lamp owing to the use of the shaped metal body (20), and fewer components have to be combined in the manufacture of the lamp.

  • Patent number: 6577046
    Abstract: The electric discharge lamp comprises a shell (1) having an axis (2), which shell accommodates a starter (3) and pin-shaped contacts (4) extending in an axial direction. A cover (27), which is coupled to a discharge vessel (20), is attached to the shell (1). Pairs (23) of current conductors (24) emanate from the discharge vessel (20). The conductors (24) of each pair (23) are clamped, in a direction transverse to the axis (2), by first and second (6) forked contact elements, which are secured in the shell (1) and are directed towards the cover (27). The lamp is of a simple construction, which can be readily produced.

  • Patent number: 6409372
    Abstract: An electric lamp includes a light-transmitting lamp vessel which is closed in a gastight manner. An electric element is arranged in the lamp vessel and is connected to current conductors which issue from the lamp vessel to the exterior. A lamp cap is connected to the lamp vessel. The lamp cap has a housing which includes a coupler formed as an integral whole with the housing. The coupler and the housing share an integral, resilient intermediate portion.
