| Zusammenfassung: | An electric lamp has a lamp vessel ( 1 ) and is provided with an illumination source ( 2 ). A central current-supply conductor ( 3 ) and a side current-supply conductor ( 4 ) issue from the lamp vessel. The electric lamp has a lamp base ( 5 ) for providing a mechanical connection of the lamp vessel and for providing a mechanical and electrical connection of the current-supply conductors. At a side facing the lamp vessel, the lamp base is provided with a notch ( 6 ) for passing through the side current-supply conductor. At a side facing away from the lamp base, the side current-supply conductor is provided with a coagulated droplet of material of the side current-supply conductor. Preferably, the coagulated droplet is made by laser heating of a portion of the side current-supply conductor issuing from the notch. According to the invention, the side current-supply conductor is reliably connected to the lamp base while soldering is dispensed with. |
