Light Guide
A light guide, including a light input surface, a longitudinal path, a lateral surface, wherein at least a portion of the lateral surface is configured as a light exit surface, wherein a first and a second light guide section includes a plurality of light redirection elements, which are configured to redirect light towards the light exit surface, wherein the light exit surface is a curved surface with a primary focal line, wherein each light redirection element has a certain incision-depth, which increases along the longitudinal path, wherein the light exit surface of the second light guide section has a protrusion, which has a secondary focal line, which is closer to the light exit surface than the primary focal line, wherein the light redirection elements of the first light guide section intersect the primary focal line, wherein the light redirection elements of the second light guide section intersect the primary focal line and the secondary focal line.
VEHICLE LIGHT GUIDE AND VEHICLE LAMP
To radiate light with uniform color and illuminance in a longitudinal direction, this vehicle light guide is rod-shaped and is disposed at a front portion of a vehicle. The vehicle light guide includes a base portion having a curved portion curved rearward from a front toward a side of the vehicle and guiding light from a light source so as to be emitted from an emission face at a front side of the vehicle, a plurality of prism portions arrayed in a longitudinal direction along a back face of the base portion and that reflect light forward, and a diffusing portion positioned in at least the curved portion in the longitudinal direction of the base portion and provided in a strip form on a bottom face side of the prism portions, and that diffuses light.

VIEWING DEVICE FOR VEHICLE
In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.
VEHICLE LAMP
A present invention is a vehicle lamp provided with: an elongated light guide member provided in a lamp chamber, an incident end part being positioned below said member; and a light source provided in the lamp chamber so as to face the incident end part. The light guide member has: a light guide main part having an elongated shape in which one end is the incident end part, a prism part being provided along the longitudinal direction, the prism part causing a portion of the light incident from the incident end part to be emitted in the irradiation direction; and a flange part projecting from the light guide main part in the direction intersecting the irradiation direction. The flange part is provided with a reflecting surface that forms a depression angle with a projecting end face when viewed from the incident end part side within a prescribed range viewed in the longitudinal direction.
ACCESSORY MOUNT ASSEMBLY FOR MOTOR VEHICLE
A mount assembly for attaching a light bar to a tow mount of a vehicle. The mount assembly has a bracket with a channel that allows the tow mount to only enter the bracket from a first direction. The tow mount is secured within the channel by a blocking member that extends across at least a portion of the channel.
Illuminating device for vehicle ceiling lamp
The invention relates to a device for generating light, in particular for a vehicle passenger compartment ceiling lamp (100), comprising: a separating tube (7) made of a material that is opaque to the radiation used, which is intended to be placed in an aperture (101) forming an exit for the illuminating light, is tubular along an axis orthogonal to the aperture and is of “c”-shaped radial cross section, forming an axial window (71), a bounding light guide (53) encircling the separating tube (7) having an annular exit dioptric interface (55), a base (57) in the axial extension of the exit dioptric interface, axial extensions (59), extending axially at least in segments the base (57), comprising entrance dioptric interfaces (61), which are placed facing bounding light sources (51), an illuminating light guide (33), which is located axially facing the illuminating light source (31) of the separating tube and axially removed from the aperture (101) comprising an entrance dioptric interface (35), which is placed facing an illuminating light source (31), a total reflection surface (39), from which light entering via the entrance dioptric interface (35) is reflected at a predefined angle of inclination with respect to the normal to the entrance dioptric interface (35), and an exit dioptric interface (37), via which the light reflected from the total reflection surface (39) is emitted in the direction of the aperture (101).
OPTICAL ELEMENT AND CORRESPONDING VEHICLE LAMP AND VEHICLE
The present utility model provides an optical element, comprising: a light entry surface; a first reflective surface and a second reflective surface; a light exit surface; and at least one connecting surface, located between the first reflective surface and/or the second reflective surface on the one hand and the light exit surface on the other, wherein the connecting surface at least partly comprises an enhanced reflection part for expanding a maximum exit angle of emergent light exiting via the light exit surface. Advantages: there is no need to process a surface at the light exit surface, so the range of applicability of the optical element is increased; moreover, the optical element according to the present utility model has a greater distance between the light exit surface and light entry surface thereof, i.e. can be thicker, so the optical element can adapt to a greater variety of shapes.
