Abstract

In a radiant heater (1) an illuminated display (20) is provided for at least part of the heating field (12) and has a low voltage halogen lamp (22) and a glass rod light guide (30) located at a limited distance below the glass ceramic plate (2) and led away from the lamp with at least one light entrance (32). The light guide circularly, spacedly surrounds the outer circumference of the heating field (11) with a display portion and over the length of the latter are distributed light exits (40) in the form of notches (44) or the like. Thus, a corresponding, horizontal, circular display field (45) is formed on the outside (4) of the glass ceramic plate (2). Thus, even when a cooking utensil is in place, the illuminated display (20) can be seen from a considerable distance and the lamp (22), protected against overheating, can be located outside the heated area.
