Abstract
A body defines a void and an aperture and has a reflective surface, the void communicating with the aperture and the reflective surface presenting towards the aperture. A structure, adapted to produce infrared radiation, is positioned in the void such that infrared radiation produced by the structure is directed to the aperture. An optical filter is positioned to at least substantially occlude the aperture, the filter being adapted for through passage of the infrared radiation directed to the aperture and further being adapted to restrict the through passage of visible light.
Claims4
A heater comprising:
- an emitter arrangement, the emitter arrangement being adapted to emit radiant energy;
- a disc adapted to permit throughpassage of radiant energy, the disc being flat and free from protrusions and defining a round outer edge, the disc being disposed beneath the emitter arrangement;
- a body shaped in the manner of an inverted-bowl, the body having a top portion and defining a circular rim at a lower extent of the body, the body being disposed around the emitter arrangement and around the disc, the rim being adjacent the round outer edge of the disc, such that the emitter arrangement is between the top portion of the body and the disc;
- wherein the body is annular and has a central axis;
- the disc is orientated perpendicular to the central axis;
- the body has a top portion that is orientated perpendicular to the central axis;
- and
- the emitter arrangement is disposed in surrounding relation to the central axis and in a planar arrangement that is perpendicular to the central axis;
- and
- wherein the emitter arrangement is defined by a plurality of linear emitters;
- and
- for each emitter, a parabolic reflector.
