Abstract: The disclosed light directing article has an optical element and a conformal retarder with predefined thickness that contours with the optical element. In one aspect, the light directing article is a retroreflective article, which further comprises a phase reversing optical reflector.

Abstract: Lighting systems include a light-transmissive tube and a light source assembly disposed to inject light into a cavity defined by the tube. The cavity extends along a longitudinal axis. At least a portion of the tube includes an inner structured surface facing the cavity, and an outer structured surface facing away from the cavity. The inner structured surface is configured to direct a first portion of the injected light towards the outer structured surface, and a second portion of the injected light back into the cavity. The inner structured surface includes elongated first features and the outer structured surface includes elongated second features. At least one of the elongated first features and the elongated second features are oriented obliquely relative to the longitudinal axis such that they form respective helixes along the tube.

Abstract: The invention is related to a process to apply a heater function to a plastic glass that was made of a polycarbonate. The process includes a sputtering process that allows producing high performance heater function on a plastic glass. Another aspect of the invention is the plastic glass mirrors produced by the inventive process.

Abstract: A reinforced polypropylene mirror assembly, and process for making the same, are described. The mirror assembly, especially the components thereof, includes a long glass fiber reinforced polypropylene material. Additionally, various additives may also be included in the reinforced polypropylene material, such as a UV stabilizer. Because of the physical properties of the reinforced polypropylene material, it is possible to combined several individual components of a conventional automobile side view mirror assembly into single, integral components, thus reducing part content, vehicle weight, and construction costs.
