Abstract
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 heat-conductive stud is intimately disposed between the layer and the pinch seal, via an aperture in the housing, so as to provide a good heat-conductive path from the pinch seal to the relatively cool glass ceramic.
