摘要:
An electric lamp (10) (e.g., infrared) including a sealed outer envelope (11) having a sealed end portion (13) in which are positioned a pair of electrical conductors (15, 17). Centrally positioned within the outer envelope is a sealed inner, light-transmitting envelope (21) which includes therein a coiled tungsten filament (23). A pair of conductive members (27, 29), 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 (41) 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.
摘要:
A tungsten-halogen lamp including a tubular quartz envelope wherein both of the lead-in conductors designed for providing electrical energy to the lamp's coiled filament are strategically positioned within a single, press-sealed end portion of the lamps envelope. Electrical connections to the lamp may thus be provided and only one end thereof to thereby facilitate positioning and connection of the lamp within a photocopier or similar machine.
