| abstract | 1329778 Infra-red lamps SIEMENS AG 7 Dec 1971 [10 Dec 1970] 56713/71 Heading H1F An infra-red emitting filament lamp has an envelope 1 consisting at least in part of elemental silicon. Preferably the envelope is in the form of a tube closed at one end, having a wall thickness of between 0À5 and 4 mm. and a diameter of between 20 and 60 mm. and is made of pyrolytically deposited polycrystalline silicon. A window region 3 of reduced width may be provided opposite the filament 9 of silicon, silicon carbide or tungsten. The envelope is closed by a silicon, glass or quartz base 2 surrounded by a cup-shaped member 4 sealed off by a silicone adhesive 5. The envelope need not be made entirely of silicon, part of it may also consist of molybdenum, for example. The silicon envelope filters out the visible and short wave infra-red but permits radiation of wavelength above 1À1 Á to pass. The silicon envelope may be formed by deposition on to a heated tubular graphite body by the reaction between hydrogen and SiHCl 3 , for example, in a quartz reaction vessel. |
