-6- ABSTRACT: A mains voltage incandescent lamp has inside the lamp vessel (1) a frame (5-8) composed of current supply conductors (5,6) and glass beams (7,8), in which a filament (9) comprising several parallel sections (10-13) is stretched. Two sets of supports (17 and 18) are anchored in the beams (7 and 8, respectively). The supports (17,18) each consist of a wire hook which engages the filament (9) between a respective pair of adjacent sections (11, 12 and 10, 11). The supports (18) of at least one set each have an end portion (19) extending in a direction which is transverse to the main length of the respective support and is located at a given distance from the bend (20) of the hook. This permits the sections (10-13) to be under the same tension.
