  • Publication number: 20220268992
    Abstract: A method for manufacturing a Paspol light guide includes disposing a plurality of light guides adjacent to one another so that the light guides form a light-guide bundle, disposing an at least partially light-transparent fabric along at least one partial section of the light-guide bundle, sheathing the light-guide bundle by the fabric so that the fabric forms a fabric sleeve, and closing the fabric sleeve along its longitudinal side. When viewed in a cross-section, the fabric sleeve forms a flag protruding from the light-guide bundle.

  • Patent number: 10953792
    Abstract: An optical conductor has several spherically curved light-extraction areas on its surface that are arranged in spaced relationship to one another and have a particular height (h) and a particular radius (R) of surface curvature, wherein h/R ratios of the respective height to the respective radius of all light-extraction areas are substantially equal and lie within a range of 0.1 to 0.45. A lighting system comprises one or more optical conductors and one or more light sources for irradiation of at least one light-injection area of the optical conductor, wherein useful light radiated from the front of the optical conductor can be emitted unscattered from the lighting system and/or interference light emitted outside of a useful light path is absorbable by the lighting system. Some embodiments may be particularly applicable in vehicle lighting systems.

  • Patent number: 10279737
    Abstract: An illuminating device for a vehicle includes a carrier module, a flat light guide attached to the carrier module with a plurality of emitting points, and multiple light sources for illuminating the light guide. The flat light guide is concealed with a translucent haptic layer, which is attached to a visible side of the light guide, which, in turn, is covered by a decorative layer. The illuminating device comprises a rope-like light guide, which has an inherent light source and is connected to the decorative layer via a retaining device. This therefore results in a flat arrangement, which can be easily integrated into the interior parts and simultaneously enables illumination over a large surface area. In doing so, additional light effects can be integrated by means of the rope-like light guide. The illuminating device is not visible while switched off, as the illuminating device is covered by the decorative layer.

  • Publication number: 20140340920
    Abstract: The invention relates to a device for illuminating an assembly in the interior of a vehicle. The device comprises a flat light guide that is at least partially covered by an optical lacquer coat. The flat development of the light guide makes it easier to homogenously illuminate large faces. The optical lacquer coat protects the light guide in particular at the places where contamination must be feared or where a contact with additional assembly elements is planned. The optical lacquer coat has a defined refractive index and therefore controls the emergence of light rays at the surface of the light guide. An adhesive connects the lacquer coat to a cover element of spacer fabric and lining. This leads to a mechanically secure fastening of the light guide to the cover element that is to be backlit.
