    摘要： A lighting device for a motor vehicle having a light source, a light guide with an entrance surface, and a hologram disposed on or in the light guide. The lighting device is configured such that light emanating from the light source enters the entrance surface of the light guide and interacts with the hologram so that an image stored in the hologram is reconstructed and is visible to an observer of the lighting device. The light guide has a first exit surface and a second exit surface. The lighting device is configured such that light that has interacted with the hologram exits through the first exit surface and that light that has not interacted with the hologram exits through the second exit surface.

    摘要： A light-transmitting member is arranged such that light emitted from a light guide enters. Light which enters an incident end surface is emitted from an emitting end surface. The light-transmitting member has a wide width portion and a narrow width portion. A width of the incident end surface of the wide width portion is larger than a width of the light guide in a direction perpendicular to a longitudinal direction of the light guide. A width of the incident end surface of the narrow width portion is smaller than the width of the incident end surface of the wide width portion. The incident end surface has a curved surface convex toward the light guide at least in the wide width portion. A curvature of the incident end surface in the wide width portion is greater than a curvature of the incident end surface in the narrow width portion.
