  • Patent number: 12510219
    Abstract: A lighting system (1) for a vehicle light is disclosed, including a first illuminant (L1), a second illuminant (L2) and a light guide (4), which is arranged relative to the first illuminant and the second illuminant in such a way that light emitted by the two illuminants enters the light guide and exits via a light exit section (4c) of the light guide, wherein the lighting system has a light guiding channel element (6), which is arranged between the second illuminant and the light guide, wherein the light guiding channel element has a plurality of light guiding channels (7) arranged next to one another, wherein each light guiding channel has a wall (8), which is designed in such a way that a light beam from the second illuminant gets wider in a first plane (E1) and narrower in a second plane (E2) orthogonal to the first plane.

  • Publication number: 20250291122
    Abstract: A holding device for a light guide body includes a holding body that includes a light guide receiver and that is formed from a first holding body part and a second holding body part. The light guide receiver is formed as a depression which is delimited on opposite sides by two enclosing sections of the first holding body part. The second holding body part is connected to the first holding body part such that, by an elastic deformation of the second holding body part, a width of an opening is increased by spreading apart the two enclosing sections so that the light guide body can be inserted into the light guide receiver. After removal of the deformation force, the holding body returns to its basic shape, whereby the enclosing sections enclose the light guide body inserted into the depression, and the light guide body is clamped by the enclosing sections.

  • Patent number: 10443803
    Abstract: In a lighting device for a vehicle, a light guide assembly (10) for guiding the light emitted by a light source comprises a head portion (12) with decoupling elements (18) for decoupling at least some of the coupled-in light, and also a feed line portion (11), which comprises a coupling-in region (15) for the coupling-in of light from a light source and by means of which light coupled in in this way is fed to the head portion (12). The coupling-in region (15) has a first securing arrangement (13) with at least one element protruding transversely to the longitudinal axis of the coupling-in region (15), for example a pin, by means of which the coupling-in region (15) is insertable into a first securing location in the lighting device and lockable there. The head portion (12) has a second securing arrangement (14) for securing the head portion (12) in the lighting device.
