Abstract: 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.

Abstract: An instrument cluster is provided with a display panel having a plurality of graphic areas and with a backlighting device arranged behind the display panel for backlighting the graphic areas. The backlighting device has at least one light source and at least one light-guide element, which is provided with a receiving portion facing the light source for directly receiving a light beam and with at least one transmitting portion for transmitting and guiding the light towards at least one of the graphic areas. A cover is provided for shielding rays of light passing through the receiving portion and directed onto the display panel. The cover defines a channel, which has an inlet facing the receiving portion and at least one outlet facing one of the graphic areas. The channel is shaped in such a way as to transmit light indirectly from its inlet to its outlet.

Abstract: A led indicator has a bargraph and a lighting device arranged behind the bargraph and provided with a row of LEDs controlled to produce a light bar with a length which is variable as a function of the number of LEDs that are switched on along a lighting sense; the LEDs are arranged between screens, which are spaced apart from the lower surface of the bargraph and extend at least to reach an axis which starts from the immediately preceding led orthogonally to such a lower surface.
