Abstract
An infrared (IR) radiation emitting device comprises a sinuous foil resistive element (1) which emits IR radiation when heated by an electric current. The device is configured so that the resistive element (1) emits radiation with a spatial intensity which substantially possesses a single axis. The resistive element (1) may, for example, be configured as a substantially planar spiral (3).
