Patent ID: 8702249

Claim:
An optical device for enhancing light diffusion comprising: a monolith including an optical plastic; the monolith operable to transmit light incident on one monolith surface to and through a second monolith surface, a monolith thickness being defined by a spacing between the first and second monolith surfaces; polymeric inclusions distributed throughout the optical plastic for interrupting light rays refracted by the monolith; the polymeric inclusions selected to simultaneously a) absorb a particular portion of incident light and b) diffuse refracted rays of the incident light; wherein the optical plastic, inclusions and thickness are chosen to provide a light transmissivity from about 22.5 percent to about 30 percent over a range of wavelengths from about 430 nanometers to at least about 780 nanometers; wherein the optical plastic and inclusions are liquids; wherein a homogenous solution of the optical plastic and inclusion liquids is enclosed in a pliable, transparent container; further including: one or more collimated light sources and an indicia layer; wherein the pliable transparent container is located between the light sources and the indicia layer; and, the pliable, transparent container is operable to deform and seal against an adjacent part.
