Abstract:
A method for making electrically conductive contact with and mechanically fixing a power supply element (12a) with a base element (10) of a lamp. The lamp comprises a luminous element (24), which is arranged within a closed luminous body (22) and can be connected to the power supply element (12a) so as to supply electrical energy. The base element (10) comprises at least one connection contact (28), by means of which the base element (10) can be connected to an electrical power source. The method comprises the steps of a) arranging at least one region (second end region 20) of the power supply element (12a) on an inner wall of the base element (10) and b) setting at least one weld point (18a, 18b) through an outer wall of the base element (10) onto the power supply element (12a), which is arranged on the inner wall, by means of a laser welding apparatus in such a way that electrically conductive contact is made between the power supply element (12a) and the base element (10) and said power supply element (12a) is fixed mechanically on said base element (10). Also disclosed is a lamp having a luminous element (24) arranged within a closed luminous body (22).
Abstract:
The invention relates to a method for producing an electric incandescent p which has at least one incandescent filament (31) and an anti-dazzle device (20). According to the invention, in the course of the method, an end (31a) of an incandescent filament (31) is threaded into a notch (23) on the edge of the anti-dazzle device (20) and fused with the anti-dazzle device (20) by melting the material of the anti-dazzle device (20) in the region of the notch (23) so that the melt wets the incandescent filament end (31a) arranged in the notch (23) and the incandescent filament end (31a) is embedded in the solidified material (20a) of the anti-dazzle device (20) after the melt has solidified.
Abstract:
An optoelectronic module having an optoelectronic device with a contact conductor and a connection carrier with a connection area. The contact conductor is electrically conductively and/or thermally conductively connected to the connection area. A local, delimited heating region is formed on the contact conductor or the connection carrier has a cutout, which is at least partly covered by the contact conductor. A method which enables simplified and reliable production of an optoelectronic module is also described.

Abstract:
The invention relates to a method for welding a metal foil to a metal pin, these components being intended for use as supply conductors in lamps, the metal foil being pressed onto the metal pin in order for the welding process to be carried out, and the region of the metal foil which adjoins the metal pin is heated and melted in punctiform fashion at a plurality of locations via a laser, so that after the molten material has cooled, the metal foil and the metal pin are joined to one another in the vicinity of these locations.
Abstract:
The invention relates to an electric incandescent lamp having power supply wires for at least one incandescent filament, at least one power supply wire being provided with a hole in which an outgoing filament line of the at least one incandescent filament is fixed.
Abstract:
An electric lamp has at least one molybdenum foil seal for a lamp vessel (30, 40) and at least one slotted metal pin (35, 44), the at least one slotted metal pin (35, 44) being electrically conductively connected to a molybdenum foil (32, 42) of the at least one molybdenum foil seal, characterized in that one end (321) of the molybdenum foil (32, 42) is arranged and fixed in the slot (350) in the at least one slotted metal pin (35, 44). The metal pin (35, 44) is preferably in the form of a power supply wire or a gas-discharge electrode.
Abstract:
The invention relates to a motor vehicle headlight lamp having a metal-plastic cap whose electric connections are constructed as contact lugs (16, 17). According to the invention, the two contact lugs (16, 17) in each case have a groove (16c, 17c) in which in each case a supply lead wire (12, 13) which is guided out of the lamp bulb is fixed to the corresponding contact lug (16, 17) by a welded joint. Furthermore, the contact lugs (16, 17) are equipped with means (16f, 17f) for threading the supply lead wires (12, 13) into the respective groove (16c, 17c) and the lamp cap has at least one cut-out (18) which serves the purpose of carrying out the welding of the supply lead wires (12, 13), arranged in the grooves (16c, 17c), to the contact lugs (16, 17).
Abstract:
The invention concerns an electrical incandescent lamp with a low-beam cap,articularly a two-filament halogen incandescent lamp and a production process for such a lamp, as well as a low-beam cap. Low-beam screening cap (12) has an opening (14), through which one end (6a) of low-beam filament (6) is threaded. This filament end (6a) is welded to the back side of low-beam screening cap (12) or to a current lead wire (8a), which is attached by a projection welding to the back side of low-beam screening cap (12). The fastening of low-beam filament (6) according to the invention makes possible materials savings in the case of a low-beam screening cap (12) and lower cost lamp manufacture.
