The light guide, especially for motor vehicle signal lamps, comprises a collimator with a collimating wall for binding and routing light rays, and a light guiding body that continues the collimating wall, is of a material with refractive index (n), and is integral, spatially shaped, planar, and fitted at its end with an output emitting surface providing a signal light function. The first height (d) of the body at its beginning where it adjoins the collimating wall, is bigger than its second height where it passes into the emitting surface. The body is adapted to emit light rays generally within angle (ω) of diffusion from the optical axis (x), and comprises a transitional surface that is, in its profile towards the emitting surface, inclined towards the longitudinal axis of the profile. The ratio of inclination height (a) and inclination length (b) of the transitional surface is defined as:

A light module for a motor vehicle comprising: a light guide with an input face and at least two branches each extending from the input face according to a specific length and a specific section; at least one light source arranged at the input face of the light guide, the input face being adapted to couple light rays emitted by the light source in the light guide; wherein the two branches are contiguous over a part of their length from the input face to a determined point of separation, the two sections of the branches overlapping over a zone of intersection which is present from the input face to the determined point of separation. The two sections are substantially constant along the branches from the input face over a length greater than or equal to the length of the branches between the input face and the determined point of separation.

The present utility model discloses a light guiding device and a vehicle lamp. The light guiding device includes a light guide medium component configured to allow light to be transmitted through it from one end thereof to another end thereof. A light guide fixing component is arranged on the light guide medium component and configured to fix the light guide medium component, wherein the light guide medium component and the light guide fixing component are both at least partly made of a transparent material. The light guide fixing component has a light directing portion configured to direct the light leaked from the light guide medium component into the light guide fixing component to exit the light guide fixing component away from a predetermined direction. Using the light guiding device and the vehicle lamp according to the present utility model can prevent light exiting the light guide fixing component from forming undesirable light spots in an undesirable direction.

The present disclosure refers to a light module, comprising a lens unit, which is formed with a bottom, a lid and one or more side walls between the bottom and the lid, wherein the one or more side walls provide one or more insertion openings; a printed circuit board unit, which carries one or more light sources and is inserted into the lens unit through a first insertion opening of the one or more insertion openings such that light emitted by the one or more light sources exits the light module through the bottom and/or the lid of the lens unit; and a housing unit, which is provided with a bottom opening, a lid opening and one or more side walls between the bottom opening and the lid opening, wherein the lens unit is arranged within the housing unit such that the bottom opening of the housing unit is closed by the bottom of the lens unit, the lid opening of the housing unit is closed by the lid of the lens unit, and the one or more insertion openings of the lens unit is closed by the one or more side walls of the housing unit. It also refers to an external rear view device with such a light unit.

A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.

A light-guiding element (1) for a lighting unit, comprising a light-guiding body (5) having at least one light entry face (2) and at least one light exit face (3), wherein the at least one light entry face (2) comprises a plurality of entry sub-faces (2a) offset from one another at least in the light propagation direction (−x), wherein the entry sub-faces (2a) are oriented substantially normal to the light propagation direction (−x).

The present disclosure provides a light guide assembly and a vehicle lamp. The light guide assembly includes a light guide having an elongated light guiding portion, and a light guide support, the elongated light guiding portion having an end provided with a positioning device for positioning the light guide on the light guide support. It may improve reliability of positioning the light guide by the positioning device arranged at the end of the elongated light guiding part of the light guide.

A first lamp assembly has a first side surface with a first light passage and a hollow interior with a first light dispersing member disposed therein. The first light dispersing member is positioned to receive light emitted through the first light passage and emit light received via the first light passage. The second lamp assembly has a hollow interior with a first lighting device disposed therein, and a second side surface with a second light passage. The first lighting device is positioned to emit light through the second light passage, such that when the second light passage and the first light passage are adjacent to one another with the first and second light passages being aligned, and with the first lighting device operating, the first lighting device emits light through the second light passage into the second light passage illuminating the first light dispersing member within the first lamp assembly.

A light module comprising a means for supporting at least one collector of light rays in the vicinity of which there is a light guide suitable for guiding the rays emitted by a light source from an input face to at least two distinct and adjacent output faces. A distinction is made between a main output face, through which the rays pass in a first direction, and at least one additional output face which is oriented such that the light rays leaving the guide through this additional output face are directed toward the collector, in a second direction distinct from the first direction.
