Vehicle exterior lighting systems for vehicles equipped with tailgate assemblies may be configured to provide redundant backup lighting functionality for all tailgate positions (e.g., closed, open, and removed). Exemplary systems may include both vehicle static body structure mounted backup lamps and tailgate structure mounted backup lamps for providing the backup lighting redundancy.

A lamp for a vehicle including a light source configured to emit light, and a light guide body including a light entering portion, a light exiting portion, and a recessed region disposed between the light entering portion and the light exiting portion and having a shape recessed upward in a lower surface of the light guide body, in which the recessed region includes a first surface formed in a region adjacent to the light entering portion, a second surface connected to the first surface through a first connection portion and extending toward the light exiting portion, and a third surface connected to the second surface through a second connection portion and extending toward the light exiting portion, and in which the second connection portion includes a curved connection portion.

A vehicle light optical element assembly of a vehicle lamp, and a vehicle lighting device, a vehicle lamp and a vehicle comprising the vehicle light optical element assembly of the vehicle lamp. The vehicle light optical element assembly comprises a low-beam primary optical element, a high-beam primary optical element provided below the low-beam primary optical element, and a lens provided on the front end of the low-beam primary optical element and/or the high-beam primary optical element, wherein the low-beam primary optical element and/or the high-beam primary optical element are integrated with the lens, and the low-beam primary optical element and the high-beam primary optical element are suitable for light convergence and collimation to then pass through the lens to form a low-beam illumination light shape and a high-beam illumination light shape. The vehicle light optical element assembly has the advantages of a compact structure, small volume, and high assembly accuracy.

A system for alerting motorists travelling on a roadway in a vicinity of a vehicle is disclosed. The system includes one or more projector units, and a respective attachment structure for each of the one or more projector units for attaching the projector units to a portion of the vehicle. The one or more projector units are configured and arranged to project a light signal on to at least a portion of the roadway adjacent the vehicle and in a travel path of the motorist. The one or more projector units include at least one light flare projector unit and/or at least one signage projector unit. A school bus incorporating the system is also disclosed. A method for alerting motorists travelling on a roadway in the vicinity of a vehicle is also disclosed.

To reduce uneven brightness of light irradiated from a vehicle lighting system. The system includes a lamp unit and a control unit where the lamp unit includes: a light source that emits light; a liquid crystal element using the light emitted from the light source to form irradiation light; and a lens projecting the irradiation light; where the light from the light source enters the element at an angle including a direction inclined from the normal of a light incident surface of the element; where the light incident surface has a first region in which most light enters from a viewing direction of the element and a second region in which most light enters from other directions, and where the control unit drives the element by setting a first voltage of the first region to be low and setting a second voltage of the second region to be high.

An illuminations system placed on a rear cargo van door providing auxiliary lighting to improve safety. Light modules are attached to the rear cargo van doors so that when the doors are opened an amber warning light is illuminated along the edge of the open cargo van door pointing rearward. A task light preferably is incorporated in the light modules to provide downward task lighting. The lighting modules are attached adjacent edges of the rear cargo van doors without permanent modification to the cargo van.

A road finishing machine comprises a tractor and a screed hinged to the tractor to be towed behind the tractor. At the tractor, a main control platform of the road finishing machine is provided which offers space for an operator and comprises operational controls for controlling functions of the road finishing machine. The main control platform has a roof, wherein a lighting unit with a light source is provided at the roof. The lighting unit comprises a housing which accommodates the light source and has a reflector. The reflector is configured to reflect light emitted by the light source into a working area of the screed so that the working area of the screed is illuminated indirectly.

A rotation light source lamp system is combined with a rotation light source device in which a chromatic aberration correction unit obviates focal distance differences occurring between incident paths “a” of lights emitted by LED light sources sequentially synchronized and turned on when first to N-th LED chips arrive at a location where each LED chip faces a signal transmitter while the first to N-th LED chips are rotated once in response to the application of a lamp turn-on signal for the vehicle from the signal transmitter. Chromatic aberration can be reduced by correcting a difference between refractive indices for each wavelength having a different color in the first to N-th LED chips.

The present disclosure relates to a vehicle lighting system, and discloses a headlight optical element. The headlight optical element includes a light incident portion, a transmission portion and a light emergent portion. The light incident portion includes at least one light incident structure; the transmission portion is arranged between the light incident portion and the light emergent portion, and includes a light transmitting portion located at the center, and light absorbing portions located on the periphery; and the light emergent portion includes a light emergent surface protruding outwards. The headlight optical element has the advantages of simple structure and convenient dimming. The present disclosure further discloses a headlight module adopting the headlight optical element, a vehicle headlight including the headlight module, and a vehicle adopting the vehicle headlight.

A lamp for a vehicle including a light source configured to emit light, and a light guide body including a light entering portion, a light exiting portion, and a recessed region disposed between the light entering portion and the light exiting portion and having a shape recessed upward in a lower surface of the light guide body, in which the recessed region includes a first surface formed in a region adjacent to the light entering portion, a second surface connected to the first surface through a first connection portion and extending toward the light exiting portion, and a third surface connected to the second surface through a second connection portion and extending toward the light exiting portion, and in which the second connection portion includes a curved connection portion.
