A dia for an automotive dia projection system has a transparent substrate with an opaque coating in portions thereof, thereby forming a binary pattern for projection. The pattern features a dither noise microstructure, such that an associated image is projectable giving the perception of a greyscale image to the human viewer.

A lighting device for a vehicle, comprising at least one light source, a flat light guide with an input surface and at least one output surface. The light generated by the at least one light source enters the light guide at least partially through the input surface and exits at least partially from the at least one output surface. An LC display which has two opposing, at least partially transparent plates and a liquid crystal layer is arranged between these plates. One of the at least partially transparent plates of the LC display is formed by the flat light guide. The lighting device is configured such that the light emerging from the at least one output surface of the light guide passes at least partially through the liquid crystal layer of the LC display and subsequently through the LC display plate not formed by the light guide.

A lighting device for a motor vehicle, has at least one light source, a flat light guide with an entry surface and at least one exit surface. At least one optical component is designed as an optical panel or optical film. The lighting device being configured so that the light generated by the at least one light source enters, at least in part, through the entry surface and into the light guide. The light entering through the entry surface exits, at least in part, from the at least one exit surface, and the light exiting the at least one exit surface of the light guide passes, at least in part, through the at least one optical component and/or is reflected by the at least one optical component. The flat light guide and/or the at least one optical component is made, at least in part, of silicone.

A reflective display includes a reflective spatial light modulator and a front light having a lightguide formed by an array of film-based lightguides coupled into a lightguide region of the lightguide. One or more light sources emit light into the array of lightguides, with light extraction features frustrating totally internally reflect light within the lightguide region such that the light exits the lightguide through a cladding region toward a light redirecting optical element that redirects the light toward a reflective spatial light modulator.

A warning light includes a light case assembly and a light emitting assembly. The light case assembly includes a base, a covering component, a base plate, two fastening components and two shielding components. The covering component is made of resilient or deformable material and mounted on the base. The base plate and the light emitting assembly are disposed an accommodating space between the base and the covering component. The two fastening components pass through two fixing portions of the covering component, respectively. The two shielding components are mounted on the two fixing portions of the covering component for concealing the two fastening components, respectively. When the light case assembly is positioned on a surface of a vehicle body of the vehicle by the two fastening components, the covering component is resiliently deformed, such that the light case assembly is attached onto the surface of the vehicle body of the vehicle.
