A vehicular lamp device includes a horizontal rectangular lamp body and reflects irradiation light of light sources with a reflector unit for outward irradiation via an outer lens. Four reflector portions of the reflector unit have long side reflectors and short side reflectors. The long side reflectors are contiguously arranged in the long side direction at the positions toward the long sides of the lamp device. The short side reflectors are contiguously arranged in the short side direction at the positions toward the short sides of the lamp device. Light sources are each positioned toward the center of each reflector portion in front view of the lamp device. Border lines between the long side reflectors and short side reflectors are formed along inclined lines inclined to extend from near the light sources relative to the long side direction.

A light device for a motor vehicle is provided that contains a rod-like light guide (1) having a longitudinal axis (15) connecting two ends of the light guide (1), and a primary light source (2) at least one of the ends of the light guide (1) for emitting primary light rays (10) in the light guide (1). The light guide (1) comprises a front output surface (4) for the output of the primary light rays (10) and at a rear side (12) of the light guide (1) unbinding elements (6) to direct the primary light rays (10) propagating along the light guide (1) to the output surface (4). The light device further comprises at least one reflector unit (7) that contains a secondary light source (8) for emitting secondary light rays (11) and a reflector (9) adapted to reflect and direct the secondary light rays (11) in the form of a light stream (14) to the light guide (1), wherein in the lateral cross-section the light stream (14) has a shape of a band (13) having a longitudinal axis (3) being substantially parallel to the longitudinal axis (15) of the light guide (1), and the rear side (12) of the light guide (1) comprises a binding area (5) including binding surfaces (5 a) configured to bind the secondary light rays (11) to the light guide (1).

The present invention relates to the field of automotive front-lighting, and particularly to a front-lighting system for a vehicle. The front-lighting system comprises: a first light source, a second light source, a first primary optics, a second primary optics, a transparent shutter, and a secondary optics. The first primary optics is designed to receive light from the first light source and project it onto the transparent shutter and the secondary optics. The second primary optics is designed to receive light from the second light source and project it onto the transparent shutter. The transparent shutter is designed to receive light from the first light source via the first primary optics and prevent a lower part of it from entering the secondary optics. The transparent shutter is further designed to receive light from the second light source via the second primary optics and project it onto the secondary optics. The secondary optics is designed to receive light from the first primary optics and the transparent shutter, and project it onto a road in front of the vehicle. The transparent shutter comprises a flat or freeform light out-coupling surface and micro-optical surfaces adjacent to the light out-coupling surface.

A lighting device is provided for controlling the photometric distribution of light emitted by two or more LEDs. The lighting device may be integrated with a control system of the vehicle and may be controlled by a remote controller. The lighting device may be capable of being operated in one or more modes of operation based on operating conditions, user input, or both. Operating conditions may include vehicle conditions, environmental conditions, and user conditions. The controller may operate a software application to enable the user to modify, control, or otherwise regulate any mode of operation or other feature of the lighting system.

A vehicle light includes a light compartment, a first light emission unit, and a second light emission unit. The first light emission unit is arranged in the light compartment and includes a first light emission body and a light guide body configured to emit light by internally reflecting light from the first light emission body. The second light emission unit is arranged in the light compartment and includes a second light emission body and a reflector configured to reflect light from the second light emission body in a vehicle forward direction. The light guide body is arranged outward with respect to a vehicle widthwise direction in the light compartment, and a light emission portion of the light guide body at least partially overlaps a path of light reflected by the reflector.

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 lamp unit for illuminating a front through an outer lens includes a first light source disposed on a back side of the outer lens, a second light source disposed on the back side of the outer lens, a first light guide body configured to guide light from the first light source to the outer lens, and a second light guide body configured to guide light from the second light source to the outer lens. The second light guide body overlaps the first light guide body from a front side in a front view. The first light guide body protrudes outward from the second light guide body. A part of light from the first light guide body is transmitted through the second light guide body and guided to the outer lens.

The invention relates to a signal light for a motor vehicle that has a fiber optic rod, which has a light emitting surface and a rear surface, in which deflection elements are located, and which has two side walls, and numerous pairs of reflectors and light sources, which are in a row in the rear surface, and which project light bundles through the fiber optic rod, transverse thereto. The fiber optic rod has two rear walls, each of which has deflection element edge and side wall edge, and extends longitudinally between the deflection elements and the side walls. The side wall edges are further apart than the deflection element edges in a cross section of the fiber optic rod that is transverse to the longitudinal direction thereof.

A directional illumination device for a vehicle external light comprises an array of light sources and an imaging waveguide comprising an input surface and a reflective end. Opposed guide surfaces are arranged to guide input light from the input surface to the reflective end and back along the waveguide after reflection at the reflective end, the waveguide being arranged to extract input light as it is guided back along the waveguide after reflection and to cause the extracted light to exit through the first guide surface. The reflective end has positive optical power in the direction laterally across the waveguide and the waveguide is arranged to direct the extracted light in respective output illumination directions distributed in a lateral direction in dependence on the input positions of the light sources in the direction laterally across the waveguide. A thin, high brightness and high efficiency controllable directional vehicle headlight is provided.

An illuminable vehicle component and a method for illuminating a vehicle component includes a vehicle component including an A-surface, a photoluminescent or electroluminescent light source covering the A-surface, a pigmented layer coving the photoluminescent or electroluminescent light source, and an optional optically clear top coat covering the pigmented layer. When the photoluminescent or electroluminescent light source is not activated and is not emitting light, the pigmented layer has an opaque appearance. When the photoluminescent or electroluminescent light source is activated to emit light, light emitted from the photoluminescent or electroluminescent light source is transmitted through the pigmented layer and the optional optically clear top coat such that the illuminable vehicle component has an illuminated appearance and the component is illuminated.
