摘要： Disclosed herein is a halogen incandescent lamp in which a halogen-containing gas is sealed in a light-emitting tube made of alumina silicate glass (10) and a filament assembly (20) comprising light-emitting parts (21) and light-unemitting parts (22) is disposed along the tube axis of the light-emitting tube. The light-emitting tube comprises emitting space-surrounding portions (13), which are respectively divided and defined by constricted portions (12) formed respectively at portions close to both ends of the light-unemitting parts (22) of the filament assembly (20) and enclose respectively the light-emitting parts (21), and unemitting space-surrounding portions (14) enclosing respectively the light-unemitting parts (22), the temperature of the tube wall at the emitting space-surrounding portions (13) is increased to at least 250°C, and the halogen-containing gas to be filled is composed only of a chlorine-containing gas free of any hydrogen atoms and an inert gas. A method for the production thereof, which comprises sealing only a chlorine-containing gas free of any hydrogen atoms and an inert gas in the light-emitting tube, is also disclosed.
