An automotive vehicle includes a headlamp housing mounted to a body of the vehicle. An airflow opening extends through the headlamp housing. A light guide coupled to the housing forms a portion of an airflow passage extending from the airflow opening into an interior of the body of the vehicle. A surface of the light guide is etched with a design extending along a length of the airflow passage. An LED light generating unit is positioned adjacent an end of the light guide to pass light from the light generating unit through the light guide that illuminates the etched design.

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).

An illumination device includes a light source and a light guide including a first light guide portion and a second light guide portion. The second light guide portion contains a light-emitting face, and the excitation light emitted by the light source is coupled and enters the first light guide portion and is emitted via the light-emitting face of the second light guide portion. The area of the cross section, perpendicular to a light guide central line, of the second light guide portion is gradually decreased in the direction of an optical axis of the light source. An angle between an intersecting line of the light-emitting face of the second light guide portion and the cross section passing through the light guide central line or any tangent line of the intersecting line and the light guide central line is an acute angle.

A vehicle lighting unit, such as a rear combination lamp, can include an LED serving as a light source and a light guiding lens housed within a lighting chamber defined by a housing and an outer lens covering an opening of the housing. The light guiding lens can have a light incident surface configured to receive light from the LED and an attachment portion provided near the light incident surface and extending in a direction perpendicular to a direction in which the light is incident on the light incident surface. The light guiding lens is configured to guide and deflect the light to be illuminated with the light, and such that the thickness of a portion after the attachment portion is greater than that of a portion before the attachment portion.

The present invention relates to a daylight opening surround (3; 101) for a motor vehicle (1). The surround (3; 101) has a light transmitting element (15; 103) for transmitting light from a light source (19; 111). The present invention also relates to a light transmitting element (15; 103) for a surround (3; 101); a controller for a daylight opening surround (3; 101); and a motor vehicle (1).

Problem: To provide a vehicle lamp fitting in which regularity of the strength or weakness of the emitted light is maintained and deterioration of appearance is suppressed. Solution: A vehicle lamp fitting 10 comprises a light guide 11 which guides light from an LED light source 12 and an LED light source 13, the light guide 11 having entrance surfaces 110, 111, emission surfaces R1 to R3, and an internally reflecting surface 17 which causes light that has entered through the entrance surfaces 110, 111 to be reflected, and the internally reflecting surface 17 comprises a reflecting surface 141 which is provided in a first region 14 and which emits light from the LED light source 12 in a forward direction, a reflecting surface 151 which is provided in a second region 15 and which emits light from the LED light source 13 in the forward direction, and a reflecting surface 161 which is formed in a third region 16 between the first region 14 and the second region 15 and which limits the light intensity with which light from the LED light sources 12, 13 is emitted in the forward direction from the emission surface R3.

There is provided a resin molded product including a first member and a second member which are laser welded. A laser welded portion includes a first welding portion which is welded by laser welding of galvano method and a second welding portion which is welded by laser welding of flash method or laser welding of scanning method.

The present invention relates to a rear lighting and/or signaling device, notably for a motor vehicle, comprising a light source, a transmission surface and means for distributing at least a part of the light from the source on the transmission surface, the distribution means comprising a matrix of micromirrors that can each be driven according to at least two different inclination positions. Another source is present and a mode of operation allows the illumination of a part of the micromirrors by the source and another part by the source.

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.

A lighting device for vehicles having a laser light source and an optical unit which is associated with the laser light source and which generates a predetermined light distribution. A diffusion element is arranged between the laser light source and the optical unit for reducing and/or preventing a speckle pattern in the light distribution.
