Abstract

Improvements introduced in the incandescent electric lamps, characterized in that they comprise a tubular envelope of essentially circular section, a filament of helically wound wire extending axially to said envelope, and a plurality of disc-shaped support members disposed transversely to said filament and at intervals spaced along it and which may be applied at its peripheries to the inner wall of said shell, said discoidal members being open at the center and being applied to the helix of the filament between adjacent turns thereof to support it on the axis of said sleeve. enveloping, but being able to rotate with respect to said filament helix, and means which block said discoidal members against relative rotation with respect to the internal wall of said shell.
