Abstract
An electric lamp, such as an infrared lamp, including a sealed outer envelope having a sealed end portion in which are positioned a pair of electrical conductors. Centrally positioned within the outer envelope is a sealed inner, light-transmitting envelope which includes therein a coiled tungsten filament. A pair of conductive members, coupled to the filament, project externally from opposing sealed end parts of the inner envelope. One of these projecting conductive members is electrically connected to a respective one of the electrical conductors while the other conductive member is electrically connected to the remaining conductor through the utilization of a thin, conductive molybdenum reflector which is positioned within the outer envelope adjacent the sealed, inner envelope. This reflector thus forms part of a series circuit for the invention and also functions to assist in maintaining the inner envelope at the described central position within the outer envelope, while simultaneously functioning to reflect radiant energy in the form of light and/or heat from the invention's inner envelope.
