Abstract
Implementations disclosed herein include optical sheets comprising one or more regions including one or more optical elements. Each of the one or more optical elements includes a plurality of microstructures. The one or more optical elements can be configured to tailor the radiation pattern output from a source of illumination. The one or more optical element can be further configured to impart a visual appearance to the optical sheet that is different from a standard lenticular or prismatic sheet. In various implementations, the one or more regions can be demarcated from each other or the surrounding by borders. The borders of the one or more regions can be configured to form one or more letters, one or more symbols or logos for identification and/or security purposes. Various implementations of the optical sheet can include nano-particles in addition to the optical elements to enhance the aesthetic quality of the optical film.
