The invention discloses a light-emitting ornament for a vehicle and the vehicle. The light-emitting ornament comprises a base body and a light guide film attached to the base body. The light guide film comprises a light emitting surface and a bottom surface opposite to the light emitting surface, and the bottom surface is close to the substrate; a plurality of optical microstructures are constructed in at least partial region of the light guide film, and the plurality of optical microstructures form a preset pattern. Light propagating in the light guide film changes the propagation direction after passing through the plurality of optical microstructures and is emitted from the light-emitting surface so as to present a preset pattern on the light-emitting surface. And light rays not passing through the optical microstructures are not emitted from the light-emitting surface. Therefore, the pattern on the light-emitting surface is clear and sharp, so that the light-emitting ornament does not need a baffle plate and a uniform light film, the thickness of the light-emitting ornament can be reduced, and the light-emitting ornament can be conveniently used in a narrow space.
本申请公开了一种用于车辆的发光饰件和车辆。该发光饰件包括:基体和附接在基体上的导光膜。导光膜包括出光面和与出光面相对的底面,并且底面靠近基体;在导光膜的至少部分区域中构造有多个光学微结构,多个光学微结构形成预设图案。在导光膜内传播的光线过多个光学微结构后,改变传播方向并从出光面射出以将预设图案呈现在出光面上。未经过光学微结构的光线不从出光面射出。这样,出光面上的图案清晰、锐利,使得发光饰件无需遮挡板和匀光膜,这有助于减小发光饰件的厚度,以便于发光饰件在狭小的空间中使用。
