Abstract (en)

An automotive lighting appliance (1) comprising at least one lighting assembly (4) that emits light on command and is arranged inside the rear body (2) so as to be able to selectively backlight a corresponding transparent or semi-transparent sector of the front half-shell (3); the lighting assembly (4) comprising: a radial emission optical fibre (6) having a predetermined length; an electrically-powered collimated light source (5) that is arranged inside the rear body (2), in front of a proximal end (6a) of the optical fibre (6), and is able to selectively direct, towards the same proximal end (6a), a collimated light beam that enters and travels inside the optical fibre (6); at least one proximal photometric sensor (10) which is arranged next to the collimated light source (5) to capture/detect the light reflected/scattered on entering the optical fibre (6); at least one distal photometric sensor (11) that is arranged in front of the distal end (6b) of the optical fibre (6) and is adapted to capture/detect the light coming out of the distal end (6b) of the optical fibre (6); and an electronic control unit (7) which is adapted to command the collimated light source (5) based on the signals coming from said proximal (10) and distal (11) photometric sensors.
