The light device, especially a signal lamp, for motor vehicles, comprises a carrier housing and a translucent cover of the carrier housing that delimit an inner chamber, wherein a planar light-guide is mounted to conduct light rays generated by a lighting element comprising at least one light source, and to emit them from at least a part of the front surface of the light-guide. In the area of the front surface, elevations and/or recesses are formed comprising surface areas of parts of macroscopic crystals

A vehicular lighting apparatus is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus attachable to a front end of a vehicle includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.

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 vehicle lamp is provided. The vehicle lamp includes a base, a first reflection structure, a second reflection structure, a first light emitting structure, a second light emitting structure, and a lens structure. The first reflection structure and second reflection structure are disposed on the base. The first reflection structure includes at least one first focal point and at least one second focal point. The second reflection structure includes a first focal point and a second focal point. The first light emitting structure and the second light emitting structure are disposed on the base. The lens structure includes a lens optical axis and a lens focal point.

A lighting device for a vehicle includes a lighting module for a vehicle having a light source and a panel optically coupled to the light source. The panel includes a plurality of fibers, and a first illumination region of first light output for a first vehicle lighting function and a second illumination region of second light output for a second vehicle lighting function.

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 lighting device for vehicles with a first lighting unit having a light source and a light beam surface for emitting light and with a second lighting unit containing a light source and a flat light guide having opposite flat sides and narrow sides connecting the same for backlighting the first lighting unit. The flat light guide of the second lighting unit has a backlighting section and a linear light section. The backlighting section is arranged behind the first lighting unit and a front flat side of the flat light guide in the backlighting section serves as a light decoupling surface for the light decoupling of a first part of the light coupled into the flat light guide. The linear light section is at least partially arranged next to the first lighting unit. A narrow side of the flat light guide serves as a light decoupling line.

A light iodide includes a plurality of optic fibers configured as an optic fiber panel, wherein a mounting axis is positioned parallel to the optic fiber panel, a normal axis is positioned perpendicular to the optic fiber panel, a light axis is positioned in line with a targeted light transmission direction, and a material bias axis representing an actual light transmission direction is positioned a predetermined radial amount from the normal axis; and a first light source coupled to a first end of the optic fiber panel, wherein a direction and power of transmitted light rays from the first light source through the optic fiber panel are adjustable to align the material bias axis with the light axis.

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 vehicular lamp includes a lamp housing; a base substrate disposed in the lamp housing; and a plurality of planar light sources. The plurality of planar light sources are disposed spaced apart from each other on the base substrate. Each of the plurality of planar light sources has a light emitting surface that protrudes from the base substrate and that forms a respective acute angle with the base substrate relative to a forward direction of the vehicular lamp.
