Abstract
A light guide enabled lamp includes a light guide. A light source positioned at an edge of the light guide directs light generated by energizing the light source throughout a length of the light guide reflective layer disposed on the light guide. A reflective layer is disposed on the light guide. A graphics pattern is formed on the light guide defining nano-scale optic patterns by a surface etching of the light guide. A polymeric material coating is applied over the light source, the light guide and the reflective layer. A coating is applied over the polymeric material coating using one of a wet coating process, a dry coating process, an in-mold injection-compression or lamination film application, and a post molding process.
