Abstract (en)
[origin: US4794233A] A radiant heater has a shallow shell-like support for carrying heating resistors and a glass ceramic top plate. A connection and hot warning indicating device is arranged in the space between the top plate and the support. The light source is preferably a low voltage tungsten halogen lamp which projects, at most, slightly beyond the front side of the support. Despite a very compact construction, the radiant heater is not subject to dazzle effects even over a large area, and a readily visible indicating illumination is obtained. The light source can be operated at different brightness levels, for example one brightness level indicating the switched-on condition of the heating resistor and the other brightness level indicating the hot-to-touch condition of the top plate, notwithstanding the switched-on or switched-off condition of the heating resistor.
