Each infra-red lamp 3 comprises a tungsten filaments supported within a tubular quartz envelope 4 and a pinch seal 15 is formed, at least at one end of the envelope 4, having an electrical connector 22 sealed therein. The pinch seal 15 is housed within a ceramic 16 and supported by a flange 17 or 18. To cool the pinch seals 15, apertures 19, 20 are provided in the housing 16 and/or the supporting flanges 17 or 18 to permit dissipation of heat from within the housing 16 to the ambient environment of the apparatus. Apertures may also be provided in a carrier plate 8, which indirectly supports the housing 16.
