权利要求

1. An electric filament lamp comprising: an evacuated tubular envelope having a pinch seal on at least one end; a halogen atmosphere within said evelope; current conductors embedded within one pinch end; two series-arranged filaments stretched parallel to each other in the longitudinal direction within said envelope, said filaments being electrically connected to said current conductor at ends proximate to said pinch seal; a brace within said envelope and electrically connected to said filament ends remote from said pinch seal, at least the end portions of said brace being formed as mandrils which are screwed into respective ends of said filaments, the brace and filament ends making mechanical contact in a direction substantially parallel to the longitudinal direction of said envelope, said brace including a central loop portion having at least three in the longitudinal direction of said envelope turns having a common winding axis; and a supporting wire within said envelope and embedded in said pinch seal, said supporting wire having a substantially hook-shaped bent end extending into said loop portion to maintain the brace at a distance from the pinCh seal, said turns of the loop portion except those most remote from one another being secured to said supporting wire.

2. An electric filament lamp as claimed in claim 1 wherein said supporting wire extends axially in the lamp at least over a distance corresponding to the length of said filament at a distance beyond the space present between said filaments.
