A safety-related signalling device for a motor vehicle including a light guide, a first light source capable of emitting a light beam that illuminates a lateral face of the light guide to allow the light beam to propagate in the light guide, and a reflective screen having a front face located at a distance and across from a rear face of the light guide. The light guide is translucent and light-coloured, and the reflective screen promotes diffuse reflection of the light from the light guide so as to homogenize and intensify, on a front face, the light emitted by the light guide.

An IR illuminator used during the operation of autonomous vehicles, which provides improvement in the performance of cameras used in the vehicle at night time. An optical design of an outer lens of the IR illuminator is selected so that the outer lens forms a beam pattern for the output light from the IR light source, and also acts as a light guide for light emitted from a secondary visible light source, which is located in the same module as the IR light source, and which may be positioned on the same or a different printed circuit board as the IR light source. The material of outer lens is opalescent including scattering bodies. The optical design of the outer lens allows for improved field of view of the IR illuminator.

A liftgate lighting system for a vehicle includes a liftgate assembly having a first liftgate panel and a second liftgate panel. Each of the first liftgate panel and the second liftgate panel is operable between an opened position and a closed position. The second liftgate panel has a proximal end and a distal end. A sensor proximate to the proximal end of the second liftgate panel. The sensor defines a sensor field. A lamp assembly is coupled to the second liftgate panel. A controller is communicatively coupled to the lamp assembly. The controller activates the lamp assembly and the lamp assembly directs light to a ground area proximate to the second liftgate panel when the lower liftgate panel is in the opened position.

A communication apparatus is provided through a grille of a vehicle. The apparatus communicates with the outside through the grille of the vehicle and improves driving performance of the vehicle due to improvement in aerodynamic performance through the grille of the vehicle.

A method for correcting a light pattern provided by a first lighting device and a second lighting device. The first lighting device projects a first light pattern and the second lighting device projects a second light pattern. There is an overlapping zone between the first light pattern and the second light pattern. The method includes the steps of, for each lighting device, dividing the light sources in groups, each group being associated to a projection distance, calculating an overlapping region as a function of the projection distance, calculating a number of affected light sources for each group as a function of a representative dimension of the overlapping region and attenuate the intensity of the light emitted by the affected light sources in each group of each lighting device, following a monotonic attenuation pattern from 100% attenuation in the first affected light source to 0% in the last affected light source. The invention also provides an automotive lighting device assembly with control means to perform the steps of this method.

A lighting apparatus includes a plurality of fiber optic panels coupled to respective light sources. The fiber optic panels include a set of optical fibers configured to emit light transversely to the optical axis thereof to form respective illumination regions in the fiber optic panels. A housing is included in the lighting apparatus to have an internal chamber and at least one window formed therein by which the internal chamber is in optical communication with the exterior of the housing. Additionally, an optical system such as a reflector or lens can subtend the light from the distal ends of the fibers within the chamber. Fiber optic panels are optically coupled to the housing assembly to convey light into the internal chamber while the illumination regions extend from the housing to perform a lighting function of an automotive vehicle.

A rear window that is provided with a vehicle display device for displaying information toward the outside of the vehicle, includes a rear display portion on which the information is projected, in which in which at least a part of an outer surface of the rear display portion has hydrophilicity.

A light blade body for a lighting device, for example for an automotive vehicle, includes an in-coupling portion configured to be optically coupled to and collect light from a light source, a propagating portion extending along a longitudinal axis between a proximal end and a distal end where the propagating portion is configured to receive light from the in-coupling portion at the proximal end and guide light to the distal end, and wherein the propagating portion includes mixing optics to mix the light in advance of reaching an out-coupling portion. The body includes the out-coupling portion proximate the distal end of the propagating portion and is configured to emit light.

A vehicular illumination system includes a ground illumination module disposed at a side door of a vehicle. The ground illumination module includes a reconfigurable display element and at least one light source operable to emit light. When the at least one light source is electrically powered, light emitted by the at least one light source illuminates a ground region adjacent the vehicle. When the at least one light source is electrically powered, light emitted by the at least one light source passes through the reconfigurable display element and the ground illumination module projects an icon established by the reconfigurable display element onto the ground region. The reconfigurable display element is reconfigurable to form the icon responsive to programming of the reconfigurable display element for an icon.
