ABSTRACT:
An incandescent lamp includes a base, a first stiff lead-in wire and a second stiff lead-in wire, a connector, a filament and a non-opaque tubular envelope. The base is formed out of a non-conductive material. The first and second stiff lead-in wires, respectively, extend from the base. The connector is electrically coupled to the first and second stiff lead-in wires and mechanically coupled to the base. The filament has a first end and a second end which are electrically coupled to the first and second lead-in wires, respectively. The filament is formed out of a conductive wire in the shape which provides a radiation area which is similar to the illumination area of the bundle of optical fibers so that the radiation fills the illumination area within the geometric boundaries imposed. The non-opaque tubular envelope has an open end and a closed end and is mechanically coupled to the base at the open end. The base press-seals the non-opaque tubular envelope to form an enclosed chamber.
