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 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.
