Abstract

An infrared halogen emitter used in the field of radiation heating, comprising a tungsten filament (1) and a protective casing (2) combined with a filter (4) limiting the light intensity. It comprises a control device designed such that the filament (1) emits at a temperature of between 1500 and 1800K, and the protective casing (2) has the shape of a tube, while the filament (1) is arranged inside the protective casing and comprises a series of curvatures, changes of direction and straight segments, such that it has a shape that enables it to occupy a large portion of the inner space of the casing (2), and so as to house a significant quantity of tungsten inside the casing (2), i.e. a quantity suitable for enabling operation within said temperature range.
