Abstract (en)
[origin: WO2022207293A1] The invention relates to a lighting device (1) for a motor vehicle, comprising a light guiding body (2) having a first outer surface (3), which is free of a dedicated light output coupling structure, and a second outer surface (4), the outer surfaces (3, 4) being spaced apart from one another by way of a thickness of the light guiding body (2). Furthermore, a light input coupling surface (5, 12), which is different than the outer surfaces (3, 4), and a light output coupling region (9), in which a dedicated light output coupling structure (7) is formed on the second outer surface (4), are provided on the light guiding body (2). The light output coupling structure has a light output coupling element (8) and is constituted in such a way that, in a luminous operating mode, the light output coupling region (9) is a nontransparent region of the light guiding body (2) and, in a nonluminous operating mode, the light output coupling region (9) is a transparent region of the light guiding body (2). A portion of a design element (18) attached to a design surface (15) of a design carrier (14) of the lighting device (1), said portion being covered by the light output coupling region (9), is visible to a human observer in the nonluminous operating mode and is not visible to a human observer in the luminous operating mode.
