In an instrument panel, a LED backlighting device has at least one LED source, the optical axis of which corresponds to the direction in which the intensity of the emitted light is maximum; the light of the LED source is reflected onto a graphic area by means of a first and a second reflecting surface; the first surface defines a first cavity and is aligned with the graphic area along an illumination axis spaced apart from the optical axis, while the second surface is aligned with the LED source along the optical axis and defines a second cavity communicating with the first cavity through an aperture; the second surface is a cylindrical surface, defined by an elliptical generatrix and configured so as to block the light rays that would be directed from the LED source onto the graphic area.
