AN IMPROVED MOUNTING STRUCTURE AND RELATED METHOD BOTH FOR A MULTI-FILAMENT INCANDESCENT LAMP ABSTRACT OF THE DISCLOSURE An improved mounting structure for a three-way incandescent lamp is disclosed. The improved mounting structure has a three-pillar stem in which the conductive leads rigidly dispose a minor and major filament within the three-way incandescent lamp. The improved mounting structure has a conductive support member in common with both the minor and the major filaments which achieves improved mounting stability of the minor and major filaments relative to prior three-way incandescent lamps. Also disclosed is a method for the improved mounting structure which simplifies the manufacturing process of the three-way incandescent lamp. Further disclosed in one embodiment is an improved mounting structure which achieves simultaneous burnout of minor and major filaments of the three-way incandescent lamp.
