ABSTRACT:
A radiant heating element (11) contains on the surface (16) of an insulating support (14) heating resistors (18), which emanate from terminals (20), which are arranged in regular spacings on the outer circumference of the heating area (21) and are connected there to semicircular ring circuits (22, 23). The heating resistors run from the outside to the inside in nested double spirals (30, 31), reverse there in return bends (32) and then run parallel back again to the outside. This gives a very uniform, almost completely symmetrical arrangement, so that the glowing state is rapidly reached and a uniform glow pattern is obtained.
