Abstract

See full text

An optical system includes an optical film curved about a first axis and a light control film curved about the first axis. The light control film can be disposed between a light source and the optical film. The optical film includes a microstructured first major surface and an opposing second major surface. The microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces the light control film. The light control film can include a plurality of alternating optically transmissive and optically absorptive regions extending longitudinally along the first axis such that in a cross-section orthogonal to the first axis, for at least a majority of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.
