ABSTRACT:
A heating assembly including at least one infra-red emissive tungsten halogen lamp supported beneath a glass ceramic cooktop which allows useful quantities of the infra-red radiation, as emitted by the lamp (or lamps) and directly incident on the undersurface of the cooktop, to emerge from the assembly and above non-metallic, thermally insulating material contained as a layer in the base of a shallow tray. The layer contains, or supports at its surface, material which efficiently reflects the infra-red radiation emitted from the lamp (or lamps) substantially unchanged in spectral content so that useful quantities of the radiation so reflected and then incident on the undersurface of the cooktop emerge from the assembly to supplement the directly incident radiation.
