The invention relates to a motor vehicle lighting device (1) having a lighting element (2) with a plurality of light sources (3) and a cover element (4) designed to switch between a transparent operating state and an opaque operating state. In order to be able to improve the display of a contour on a motor vehicle lighting device, it is provided that the cover element (4) has a plurality of cover sections (5), the transparent operating state and the opaque operating state of each of the cover sections (5) being individually controllable, the motor vehicle lighting device (1) has a light guide element (6), the light guide element (6) being designed to guide the transparent operating state and the opaque operating state of each of the cover sections (5). Light radiated by the plurality of light sources (3) is conducted from a plurality of first coupling surfaces, on which a light guiding element (6) is optically coupled with one of the light sources (3), to a plurality of second coupling surfaces; on each of the second coupling surfaces, the light guide elements (6) are optically coupled to one of the cover sections (5), the second coupling surfaces being larger than the first coupling surfaces.

    本发明涉及一种机动车照明装置(1),该机动车照明装置具有带有多个光源(3)的发光元件(2)和设计用于在透明运行状态与不透明运行状态之间切换的覆盖元件(4)。为了能够在机动车照明装置上改进轮廓的显示而规定,覆盖元件(4)具有多个覆盖区段(5),其中,覆盖区段(5)中的每个覆盖区段的透明运行状态和不透明运行状态可以被单独操控,机动车照明装置(1)具有导光元件(6),其中,导光元件(6)设计用于,将由多个光源(3)辐射的光从多个第一耦合表面传导至多个第二耦合表面,在第一耦合表面上,导光元件(6)分别与光源(3)之一光耦合;在第二耦合表面上,导光元件(6)分别与覆盖区段(5)之一光耦合,其中,第二耦合表面分别大于第一耦合表面。
