ABSTRACT:
The electric lamp has ceramic lamp caps (7, 8) secured to the lamp vessel (1) without the use of cement. This is realized by securing the cable (9) to the current supply conductor (5) after the lamp cap (7) has been provided. Securing is made possible by the shape of the lamp cap (7) which has a cavity (13) for the seal (2) of conductor (5), which duct runs into a recess (14) for the cable (9). A bore (15) enables the cable (9) to be connected to the current supply conductor (5) after the lamp cap (7) has been provided.
