OPTICAL SYSTEM INCLUDING LIGHT CONTROL FILM AND FRESNEL LENS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17768421 titled 'OPTICAL SYSTEM INCLUDING LIGHT CONTROL FILM AND FRESNEL LENS

Simplified Explanation

The optical system described in the patent application includes a light source, an optical film curved about a first axis, and a light control film curved about the first axis and positioned between the light source and the optical film. The optical film has a microstructured first major surface and an opposing second major surface, with the first major surface containing a linear Fresnel lens made up of multiple Fresnel elements extending longitudinally along the first axis. The first major surface of the optical film faces optically transmissive regions, and the centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.

• The optical system includes a light source, an optical film with a microstructured first major surface containing a linear Fresnel lens, and a light control film positioned between the light source and the optical film.

Original Abstract Submitted

An optical system includes a light source, an optical film curved about a first axis, and a light control film curved about the first axis and disposed between the 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 of the optically transmissive regions, a centerline between adjacent optically absorptive regions is substantially normal to a major surface of the light control film.
