The present disclosure relates to a method for operating a lighting device for a motor vehicle, wherein the lighting device has at least an exterior lamp and a control device. The exterior lamp has an illuminating area having at least two independently controllable segments each comprising at least one light source, wherein, in at least one dynamic operating mode of the control device, for at least one dynamic group of the segments comprising at least two segments a pseudo-randomized or randomized, temporally variable lighting operation of the segments of the dynamic group takes place.

A common lamp driving circuit is configured to supply current. A switching circuit is configured to selectively supply the current to either a first lamp or a second lamp that are of different types. A processor is configured to control the switching circuit such that a state in which the current is supplied to the first lamp and a state in which the current is supplied to the second lamp are repeated.

Improved light emitting diode (LED) vehicle headlamps having a dedicated daytime running lamp (DRL) component are described. In various embodiments, a combination Low Beam/DRL headlamp is provided, which uses pulse width modulation (PWM) detection to determine which of the two internal LED light sources (Low Beam or DRL) is powered on. If the Low Beam/DRL headlamp detects a PWM signal on the Low Beam voltage input then it switches to drive the DRL LEDs. If, alternatively, it detects a steady state input voltage then it switches to drive the Low Beam LEDs.

A vehicle includes a front end assembly including a headlamp assembly. The headlamp assembly includes a housing that defines a cavity and an outer lens that closes the cavity. A low beam headlamp assembly is located within the cavity. A shared cover lens is located within the cavity. The shared cover lens has an illumination region. A first light guide device directs a beam of light at the illumination region. A second light guide device directs a beam of light at an area offset from the illumination region and also at the illumination region.

A device for managing at least two light functions accommodated in a same motor vehicle light device, the managing device comprising a block of light sources for each light function, wherein the managing device further comprises: an input block configured to: provide a power supply common to the at least two light functions; indicate if the at least two light functions are activated or deactivated; a bias block configured to supply a stabilized reference voltage common to the at least two light functions; a switching block for each light function, one switching block of which is configured to deactivate one of the at least two light functions that is defined as secondary with respect to the other of the at least two light functions that is defined as having priority if the latter is activated.

An illumination device disposed on a moving body includes at least one main light source, and at least one auxiliary light source disposed in a periphery of the at least one main light source when seen along a traveling direction of the moving body. The illumination device further includes a first light guide disposed adjacent to the at least one main light source, that guides light transmitted from the at least one main light source, and a second light guide that is disposed adjacent to the at least one auxiliary light source, that guides light transmitted from the at least one auxiliary light source. The illumination device also includes an optical component that transmits the light from the first light guide and the light from the second light guide in the traveling direction of the moving body.

A polymeric substrate and a method of providing same includes providing a protection system of one or more layers on at least one first surface of the polymeric substrate, coating a spectrally controlling system on a surface of the protection system to provide an external surface, the spectrally controlling system comprising at least a light absorbing or a light reflecting layer, partially removing the spectrally controlling system from the external surface until reaching the at least one first surface of the protection system creating in the spectrally controlling system an area free of the light absorbing or light reflecting layer of the spectrally controlling system, and covering the area by depositing at least one or more substances in droplets.

A vehicle grille assembly is provided herein. The grille assembly includes a panel sealingly coupled to a substrate and defining a cavity therebetween. A light source is disposed within the cavity. A diffuser is disposed between the light source and a portion of the panel.

A lighting system for a vehicle and a corresponding motor vehicle is implemented with personalized or individualizable lighting functions. A part of a lighting device is reserved for implementing main lighting functions in accordance with legal requirements and another part of the lighting device is reserved for generating individualizable lighting functions. The part for individualizable lighting functions can be freely programmed and actuated via a user interface, such as a smartphone, within the scope of the technical power limitations of the individual lighting devices while taking into consideration legal requirements.

The present disclosure relates to exterior lighting of an automotive vehicle. Specifically, the present disclosure describes a multi-function lighting assembly wherein a plurality of lighting functions can be provided from a single output surface. The multi-function lighting assembly can comprise an optical material having a first surface and a second surface wherein the second surface is a partially reflecting surface. According to an embodiment, a plurality of light rays from a first light source can be refracted through the partially reflecting surface and a plurality of light rays from a second light source can be reflected by the partially reflecting surface. In each case, the resulting reflected light ray or refracted light ray is directed along a visual axis of an observer, thereby providing more than one light function from a single output surface.
