  • Patent number: 6765339
    Abstract: An infrared lamp with a closed-off enveloping tube which encloses an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of a long axis of the enveloping tube, determines an irradiation length of the infrared lamp in the sense of a higher irradiation output. The carbon ribbon has a length which is larger than the irradiation length by a factor of at least 1.5. With a procedure for heating a material to be processed using the infrared lamp, which makes possible short processing times in connection with a simultaneous high degree of energy efficiency, the infrared lamp may be operated such that its maximum emission lies within a wavelength range from 1.8 &mgr;m to 2.9 &mgr;m, and such that its power output comes to at least 15 Watts per cm3 of the volume enclosed by the enveloping tube over the irradiation length.

  • Patent number: 6577816
    Abstract: A radiation system has at least two elongated envelope tubes permeable to light and infrared radiation which are joined together and sealed from the ambient atmosphere, a first envelope tube of which contains an incandescent coil which is electrically connected through sealed tube ends and external contacts to an external power supply and emits infrared radiation in the near IR range; furthermore, at least a second envelope tube is provided which has an elongated carbon strip as an infrared radiator for radiation in the medium IR range, which is likewise connected through sealed ends and external contacts with the external power supply or with an additional external power supply. Preferably a carbon strip is used as the radiator strip, which is configured either as an elongated coil or forms an elongated strip.
