A grilling arrangement comprises a compartment including two tungsten-halogen lamps mounted adjacent the top of the compartment behind a screen of infra-red-transmissive material. The lamps are emissive of infra-red radiation, which grills food supported on a shelf in the compartment. Each lamp has a reflector, which is preferably parabolic in cross-section, to reflect infra-red radiation from the lamps onto the grilling surface. A control arrangement is also provided to impart oscillatory movement to the reflectors and lamps, so that infra-red radiation from the lamps is swept across the grilling surface, thereby achieving a substantially uniform distribution of intensity of infra-red radiation over the surface over a given length of time.

Grilling arrangement

Heating apparatus includes a tray having a layer of insulative material disposed therewithin, above which a number of infra-red lamps are supported. The ends of each lamp are provided with a pinch seal having an amp tag connector, which is connected to the respective end of a filament within the lamp, sealed therein. Each pinch seal is enclosed within a ceramic housing and the heating apparatus is mounted beneath a layer of glass ceramic. A plate of heat-conductive material is intimately disposed between the top surface of one or more of the ceramic housings and the under surface of the glass ceramic, so as to encourage heat from the pinch seals to conduct in an upward direction towards the glass ceramic.
