Abstract
A radiant heater with a light radiator constructed in the manner of a halogen radiator and a conventional dark radiator radiant heater is arranged in such a way that the dark radiator is arranged in a ring zone surrounding the circular light radiator. The central zone below the light radiator remains unheated. The dark radiator is positioned on an inner shoulder of the rim made from stronger insulating material and which consequently forms a ring with a L-shaped cross-section, which rests on a insulating layer.
