A lighting system for vehicle includes an LED light source, at least one waveguide having at refracting surface array configured to shape light received from the LED light source into a light pattern, and a projection lens configured to receive the light pattern and project it outwardly from the vehicle. A first waveguide may shape light received from the LED light source into a low beam light pattern. A second waveguide may shape light received from the LED light source into a high beam light pattern. Generation of the high beam light pattern may include shaping light received from the LED light source through both the first and a second waveguides. The one or more waveguides may also include one or more protrusions extending from the body of the waveguide that further shape the emitted light pattern.

A headlight for a motor vehicle includes a housing which is provided with a translucent cover pane to allow light to exit from the headlight and in which a first lighting device and a second lighting device are located. The first lighting device is provided for generating at least one portion of a dipped beam and/or a full beam of the headlight, and the second lighting device is provided for generating at least one portion of a limiting light and/or a daytime running light of the headlight. The headlight also includes a diaphragm which is opaque in a predefined diaphragm section except for a plurality of light exit points provided therein. Light is emitted via the predefined diaphragm section toward the cover pane by the second lighting device in order to generate the at least one portion of the limiting light and/or the daytime running light.

A vehicular headlight (20) includes a first light source unit (41), a second light source unit (61), a temperature sensor (47), and a control unit (110). When the temperature derating is performed on the first light source unit (41) based on the temperature in a state where the light distribution pattern (910) of a low-beam is formed, the control unit (110) controls the power to be supplied to each of a plurality of light-emitting elements (43) so that the light amount of at least a part of the first light with which at least a region (911) of a first light distribution pattern (400) is irradiated decreases as compared with that before the temperature derating.

A light emitting module including a light source and a lens into which a light beam output from the light source is input, through which the light beam passes, and in which the light beam then forms a light distribution pattern and is output, wherein the lens includes a first area that outputs a light beam for forming a first light distribution pattern that is a central portion of the light distribution pattern, and a second area that outputs a light beam for forming a second light distribution pattern that has illuminance lower than that of the first light distribution pattern and is a peripheral portion of the light distribution pattern, and a diffusion angle of the light beam output from the second area in a left-right direction is greater than a diffusion angle of the light beam output from the first area in the left-right direction.

Aspects of the disclosure include lighting assemblies and methods of using the same that leverage auto-shading laminates to support a common cavity for mixed lighting applications. An exemplary vehicle includes a lighting assembly having a common cavity. The common cavity includes an outer lens coated with an auto-shading film, a primary light source positioned behind the outer lens, a secondary light source positioned on an edge of the outer lens, and a wire embedded in the auto-shading film. The auto-shading film includes discrete substructures which vary in alignment in response to an electric field, thereby varying a transmittance through the outer lens. A controller is electrically coupled to the wire. The controller is configured to direct a switching voltage to a switch to change a state of the switch, thereby causing the wire to deliver the electric field to the discrete substructures to change the transmittance of the auto-shading film.

A vehicle lamp includes: a plurality of reflectors including a first reflector; and a plurality of light sources provided in the plurality of reflectors in a mode in which at least one of the plurality of light sources is provided in each of the plurality of reflectors, where the plurality of light sources include two or more first light sources provided in the first reflector, a light distribution pattern of light emitted from the plurality of light sources through the plurality of reflectors includes a first pattern in which a width in a vertical direction decreases toward a vehicle outer side, one of the two or more first light sources is disposed at a focal point of the first reflector, and the other of the two or more first light sources is disposed on a vehicle inner side with respect to the focal point of the first reflector.

A vehicle lamp including: a container-shaped lamp body whose front surface is opened; and a front cover assembled to a front opening of the lamp body and defines a lamp chamber inside. On a back wall of the lamp body, a plurality of beams having a substantially arc-shaped cross section and constituting a part of the back wall extend in a truss shape from an upper edge portion to a lower edge portion of the back wall.

Provided is a vehicle lamp which forms a travel light distribution pattern in which occurrence of a dark area between low and high beam light distributions is suppressed. A projection lens is divided into a plurality of lens areas, each of which has a different focal point position, and one second lens area is a low lens area. A low beam light source module is set such reflected light from the reflector is incident on a back surface of the second lens area, and a low beam light distribution is emitted from an area front surface. A high beam light source module is set such that emitted light from a high beam light source is directly incident on a lens back surface of the projection lens, and a high beam light distribution for each area is emitted from each of a plurality of area front surfaces.

An LED retrofit lamp is described. The LED retrofit lamp includes LEDs arranged into at least a first group of LEDs and a second group of LEDs, power contacts, an interface and a controller. The power contacts receive electrical power to operate the LEDs. The interface supplies control signals to operate one or more of the first group and the second group of LEDs. The controller receives the control signals and operates the first group of LEDs and the second group of LEDs independent from each other based on the received control signals.

A lamp including a light source that outputs light, a light output part that outputs the light output from the light source, and a guide part that guides travel of the light output from the light source to the light output part. The guide part extends from the light source, at a front side of the lamp, to the light output part, at a rear side of the lamp. The guide part is divided into a plurality of areas with respect to a forward/rearward direction of the lamp, and a width of one of the areas located on a relatively front side of the guide part in a leftward/rightward direction of the lamp is greater than a width of another one of the areas located on a relatively rear side of the guide part in the leftward/rightward direction.
