ABSTRACT:
To provide a mount for a halogen incandescent lamp, extending longitudinally within an elongated, for example essentially cylindrical bulb (2), the filament, preferably, is a coiled-coil filament and the mount includes a first lead-in conductor (8) which extends inwardly of the bulb and, adjacent the remote end of the bulb, is bent over in inverted V or arch shape, towards the lamp axis, and then downwardly to define an essentially arch or roof shaped construction, the second leg (15) of the bent filament being bent inwardly 180.degree. towards the lamp axis, and then downwardly towards the near end, with respect to the base, of the lamp bulb, for retention of the remote end of the filament. All legs and bent portions of the longitudinal conductor are located in a common plane, the essentially V or arch-shaped bent-over region approximately spanning the inner diameter of the bulb, but being clear of the inner walls thereof. By locating all the elements in a single plane, the construction is simplified and localized thermal stresses by contact of the lead-in wires or elements close to the hot filament against the quartz glass are avoided.
