ABSTRACT:
The invention is an elongated radiant electrical heater. An elongated parabolic shaped reflector has mounted at its focal point a ribbon heater. A thermal insulation material is mounted on the side of the ribbon heater opposite from the side of the focus where the reflector is positioned. The radiant ribbon heater is deeply corrugated with the height of each corrugation being a multiple of two to three times the width of each corrugation whereby the deep corrugations not only provide mechanical strength, but also increase effective emission per unit area of the radiant heating element.
