    Abstract: In an electric incandescent lamp having a tungsten filament with a number of light-emissive sections (5, 7) connected by a non-light-emissive conductor, complicated constructions are often used so that said non-light-emissive conductor dissipates little energy.In such an incandescent lamp according to the invention the non-light-emissive conductor consists of a piece (9) of the tungsten wire (1) from which the light-emissive sections (5, 7) have been wound helically and around which a wire (2) of a less noble metal than tungsten is wound.The lamp may be used as a copying lamp. FIG. 1e.

    Abstract: The electric incandescent lamp has a filament (2) comprising light-emitting sections (5,6,7) and non-light-emitting sections (8,9) integral therewith. A non-light-emitting section (9) has at its two ends a helically wound portion (10,11), which portions are interconnected by the tungsten wire (3) from which the filament (2) is wound. An additional tungsten wire (14) extends along the non-light-emitting section (9) and is wound around each of its helically wound portions (10,11). The incandescent lamp has a filament (2) of a simple construction, whose manufacture can readily be mechanized.
