Abstract
An electric lamp (100) including a sealed light-transmissive lamp envelope (105) having an interior space, a base fixed to the outer envelope (105), a non-insulated main conductor wire (160) within the outer envelope and connected to the base (110) at one end, a light source (140) capable of generating light within the outer envelope (105), a shroud (145) surrounding the light source (140) and mounted adjacent the non-insulated main conductor wire (160), and a first center support. The light source (140) has first and second ends. The first end is electrically coupled to the non-insulated main conductor wire (160), and the second end is coupled to a stem lead (180). The first center support (150) supports the shroud (145) and the light source (140) and mechanically couples the shroud (145) and the light source (140) to the non-insulated main conductor wire (160).
