ABSTRACT:
The electric lamp comprises a lamp vessel (1) having an end portion (3) which is surrounded by a shell portion (22) of a lamp cap (20) having screw thread. The end portion (3) has transversal indents (6). A plastic coupling member (30) having arms (33) bearing a cam (31) on their inner surface (34) and being undulated at their outer surface (35) is present in the lamp cap (20). The cams (31) are located in a respective indent (6). The shell portion (22) of the lamp cap (20) is screwed onto the coupling member (30). In the electric lamp, the lamp cap (20) is fitted to the lamp vessel (1) by assembling. The current conductors (7, 8) too may be connected to the contacts (21) of the lamp cap (20) by assembling, thus avoiding time and energy-consuming thermal processes.
