A capped electric lamp for use at mains voltage includes a lamp vessel (1), a lamp cap (10) and a mounting member (40). The lamp cap has a shell (20) and an insulator body (30), the shell being secured to the lamp vessel by an adhesive compound. The insulator body is secured to the shell. Current supply conductors (6) extend from the lamp vessel and through the insulator body, and where they emerge therefrom are connected to contact pins (31) which are anchored in the insulator body. The contact pins extend through the mounting member (40) and are secured in cavities (32) in the insulator body. The mounting member may have various different shapes, e.g., it may be composed of two parts, one of which is rotatably supported in the other. Such a lamp construction is reliable and easily manufactured.
A capped electric lamp for operation at mains voltage, comprising:
A lamp cap unit for use as an element of a capped electric lamp having a vacuum sealed vessel with an end portion (2) which is fused to a stem (3) which projects into the lamp vessel and surrounds an exhaust tube (4), the lamp vessel having an electric element therein connected to at least two current supply conductors (6) which extend from the lamp vessel alongside said exhaust tube;
