ABSTRACT:
In order to simplify mounting and rearrangement of the infra-red lamps, and to minimize the size of unheated zones, an assembly plate (1) is formed with a pattern of assembly apertures (3) having at least three-fold symmetry. The bases (2) of the lamps (6) are formed with electrical passages (4) and fastening holes (5) whose spacing is compatible with the assembly aperture pattern. The electrical terminals are formed as contact pins (17) which project perpendicular to the quartz glass tube axis, set back from the ends (8,9) thereof, and make contact with a power supply in the electrical passages (4) in the bases (2). Multiple infra-red lamps (6) can thus be mounted closely adjacent to each other on the assembly plate (1), and the mounting configuration can be changed, e.g. by 90.degree. rotation of a lamp, with minimal rewiring effort. The completed system is suitable for surface heating or drying of products passing by on a conveyor belt or other production line.
