Abstract
Optical devices include a light source and an optical article, where the optical article is an acid-free, non-yellowing pressure sensitive adhesive light guide. The light source is optically coupled to the light guide such that light emitted by the light source enters the light guide and is transported within the light guide by total internal reflection. The light guide includes a plurality of features oriented to extract light being transported within the light guide.
