Abstract

To heat horizontal surfaces on which patients are placed after surgery, an irradiation apparatus with halogen lamps is provided, the radiation of which is directed toward the horizontal surface to heat it. The surface temperature prevailing in the irradiated area of the horizontal resting surface is detected by a pyrometric sensor as long-wave infrared radiation. This temperature value is used as the controlled variable and is compared with a predetermined nominal value, such as 37.degree. C. In the event of a deviation, a control signal corrects the irradiation intensity by adjusting the power supply to the halogen lamps.
