Abstract: The present invention provides a license plate assembly comprising a light source and a license plate (100) suitable for back illumination, said license plate comprising (i) a retroreflective sheet (110) having on a base prismatic elements (111) having lateral faces intersecting the base at base edges, wherein said prismatic elements are truncated having elevated edges and truncated surfaces that are transparent and bounded by the elevated edges of the prismatic elements and/or said retroreflective sheet comprises transparent separation surfaces between said prismatic elements, said separation surfaces being bounded by the base edges of said prismatic elements; (ii) and one or more indicia (140); and said retroreflective sheet being arranged on said light source such that said prismatic elements of said retroreflective sheet are facing the light source.

Abstract: The present invention provides a license plate (10) comprising a laminate that comprises: (i) a transparent polymeric support sheet (13); (ii) a transparent retroreflective sheet (11); (iii) one or more transparent adhesive layers (12) adhering said transparent polymeric support sheet (13) and said transparent retroreflective sheet together; and (iv) indicia (14). The license plate (10) can be removably mounted to a light source for back lighting the license plate (10). The invention further describes a method of making the license plate (10) and to a license plate assembly.

Abstract: The illuminated license plate (10) for vehicles comprises a light guide (12) having opposite major front and back faces (14, 16) and side faces (18, 20, 22, 24) therebetween, and an elongate light source (26) arranged along at least a portion of at least one of the side faces (20) of the light guide (12) for illuminating the light guide (12). Furthermore, the illuminated license plate (10) comprises a light-transmissive retro-reflective film (50) and indicia (56, 58), wherein the light-transmissive retro-reflective film (50) and the indicia (56, 58) are arranged in front of the front face (14) of the light guide (12).

Abstract: The illuminated message sign comprises a light emitting device, a translucent retro-reflective film arranged to be illuminated by said light emitting device, and indicia, wherein said indicia are arranged in front of said translucent retro-reflective film. The indicia comprise at least an active part adapted for dynamically displaying variable information and may further comprise a passive part adapted for displaying invariable information.
