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).

Disclosed is a power-generating backlit trim strip for a vehicle, comprising an oscillation system (3, 4; 3, 14), an induction unit (2), a sensor (17) and a control unit (8). The oscillation system (3, 4; 3, 14) includes a movably arranged gyrating mass (3), and the induction unit (2) is used for inductively converting kinetic energy of the gyrating mass (3) into electricity. The sensor (17) is used for determining a frequency of the vehicle vibrations, and the control unit (8) is used for adjusting the resonant frequency of the oscillation system (3, 4; 3, 14) to a determined frequency of the vehicle vibrations.

A method for manufacturing a panel includes forming a path segment on a surface of a substrate from a photoluminescent material. The method further includes overlaying the path segment with an overlay material. The overlay material is configured to render the path segment substantially invisible under an ambient photopic condition and render the path segment visible under an ambient mesopic or scotopic condition.

A luminous curtain device has a luminous curtain, a side member, and a luminous module. The side member is mounted on a side of the luminous curtain. The luminous module is mounted in the side member, and projects light on ends of optical fibers of the luminous curtain. The luminous curtain device is applied on sunlight-shading products for an automobile to shade sunlight. The luminous module can project light on the luminous curtain to make the luminous curtain luminous with a decorative effect.

A skin material for vehicle interior includes a woven fabric woven by using a side emission type optical fiber and a multifilament as warp or weft, and is joined to a substrate for vehicle interior to constitute a vehicle interior material. In a surface of the woven fabric which constitutes the inside of a vehicle compartment, a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the side emission type optical fibers is in close vicinity to the substrate for vehicle interior, as compared with a virtual surface constituted by connecting side surfaces, on the inside of the vehicle compartment, of the multifilaments. Examples of the vehicle interior material in which the skin material for vehicle interior is used include door trims and roof trims.

A vehicle light includes a lighting unit with multiple light-emitting elements (LEEs), one or more couplers, a light guide and an extractor. The lighting unit has a curved elongate extension. Each of the couplers has an input aperture coupled with one or more of the LEEs and an exit aperture coupled with a first edge of the light guide and is configured to couple light from the LEEs into the light guide. The light guide is configured to propagate light via total internal reflection to a second edge of the light guide. The extractor has an input aperture coupled with the second edge of the light guide and an exit aperture configured to emit light into an ambient environment.
