ABSTRACT:
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.
