Abstract
A filament support for a helically coiled filament of a tubular double-ended incandescent lamp in which the support is in the form of a wire having a first end portion extending in a loop which is circumferentially engageable with the inner wall of the envelope, a second end portion extending substantially axially of the tubular envelope and defining an inner power lead conductively coupled to a lead-in conductor, a third portion adjacent the first portion and defining several coils each of an outer diameter less than the diameter of the first portion loop and having an inner diameter dimensioned to snugly receive an end of the helically coiled filament, and a fourth portion disposed intermediate the second and third portions and having a turned section forming an abutment which limits the position of the filament relative to the filament support.
