    Patent number: 5680009
    Abstract: To permit easy assembly of a filament for a halogen incandescent lamp hav a filament holder frame (4) to retain an essentially planar filament (11) in position, the frame is made of two pre-manufactured identical frame halves (4a, 4b). Both frame halves have a cross element (7a, 7b), having a plurality of filament holders (10a, 10b) secured thereto, and two support strut portions (8a, 9a, 8b, 9b) at the ends thereof. To assemble the lamp, the two frame halves, together with the filament (11), are placed in a suitable jig, and the filament ends are threaded on one of the support strut portions (8a, 8b) of each one of the frame halves. The filament (11) is hooked on the filament holder (10a, 10b) and, by spreading apart the frame halves, the filament is stretched. The support strut portions (8a, 8b; 9a, 9b) are then connected by welding, thus completing the frame (4), and retaining the filament in stretched position.
