摘要： A system for determining the reflectance of a reflector of a lamp of a motor vehicle. The system comprises a light source designed to emit a predetermined light beam to illuminate the reflecting surface of the reflector, imaging capturing apparatus that is arranged so as to capture a series of images) containing the illuminated reflecting surface of the reflector, a processing device that is configured so as to digitally remove a first component (LS2) associated with a first photometric quantity of the light source from the images) so as to determine a second component (associated with the first actual photometric quantity of the reflector to determine the reflectance of the reflector based on second component.

摘要： An automotive light comprising a lighting assembly which is located inside the rear body, is adapted to backlight a corresponding transparent or semi-transparent sector of the front half-shell, and comprises: a pair of light-guide bars made of photoconductive material, which extend toward each other inside the rear body, while remaining both substantially grazing the front half-shell, and have their respective proximal ends adjacent and aligned to one another; and a pair of electrically-powered light sources that are located within the rear body each adjacent to the distal end of a respective light-guide bar, and are oriented so as to direct the light produced inside the body of the facing light-guide bar; the proximal ends of both light-guide bars being shaped so as to form respective plate-like heads that are locally substantially coplanar to each other and are arranged inside the rear body one spaced beside the other, so as to form/delimit therebetween a small transversal slot, which is substantially straight and is inclined with respect to the local longitudinal axis of the same light-guide bars.

摘要： An automotive lighting apparatus is provided that includes a rear body which is adapted to be fixed to the outside or to the inside of the vehicle; a front half-shell arranged to close the mouth of said rear body; and at least one lighting assembly which is located inside the rear body and is adapted to backlight, on command, a corresponding transparent or semi-transparent sector of the front half-shell; the lighting assembly including a radially emitting optical fibre of given length; an electrically-powered, collimated light source which is located in front of a proximal end of the optical fibre, and is adapted to direct, towards the same proximal end, a collimated light beam that enters and travels inside the optical fibre; at least one proximal photometric sensor which is arranged beside the collimated light source and/or the proximal end of the optical fibre so as to capture/detect the light reflected/scattered on entering into the optical fibre; at least one distal photometric sensor which is located in front of the distal end of the optical fibre, and is adapted to capture/detect the light exiting from the distal end of the optical fibre; and an electronic control unit which is adapted to command the collimated light source on the basis of the signals coming from said proximal and distal photometric sensors.

摘要： A control system to control the quality of at least one reflector body of a lamp of a motor vehicle, comprising a light source, which is designed to emit a first light beam to irradiate the reflecting surface of the reflector body; an image capturing apparatus, which is arranged so as to capture a series of images) containing the irradiated reflecting surface of the reflector body; a processing device, which is configured so as to process the images), in order to determine the actual reflectance of the reflector body, and so as to determine a quality condition of the reflector body to be validated based on the actual reflectance.
