Infrared lamp and procedure for heating material to be processed
First Claim
1. A process for heating a material to be processed using an infrared lamp with a closed enveloping tube including an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of the long axis of the enveloping tube, determines an irradiation length of the infrared lamp, wherein the carbon ribbon has a length which is greater than the irradiation length by at least a factor of 1.5, which permits a heating rate of at least 250°
- C./second, the process comprising the step of;
operating the infrared lamp such that its emission maximum lies with a wavelength in a range from 1.8 μ
m to 2.9 μ
m, and in that its power output reaches at least 15 Watts per cm3 of volume enclosed by the enveloping tube over the irradiation length.

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 μm to 2.9 μm, 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.
