Abstract
A filament array for an incandescent lamp comprises at least five filament sections ( ) having their longitudinal axes parallel with one another and, when viewed in plan, being arranged substantially symmetrically in a polygonal configuration around the lamp axis. The filament sections are wound from a single wire and are electrically connected together in series by means of linking sections ( ) of said wire extending between corresponding ends of the filament sections, with alternate linking sections being positioned at opposite ends of the filament sections. The linking sections at the two ends of the array are supported by a set of support members ( ) extending from respective frame members ( ). The electrical input and output ( ) of the array are through terminal wire sections on opposite or substantially opposite sides of the array. The linking sections are configured such that said set of support members ( ) at each end of the array are substantially collinear, and said frame members ( ) each comprise a single straight member.
