Abstract
A light device includes a transparent substrate having a first surface and a second opposite surface, an array of light-modifying elements formed on the substrate, and a light source to project light along a thickness direction of the substrate. The light-modifying elements having surfaces inclined at an angle with respect to at least one of the first surface and the second surface, and configured to diffuse light by reflecting and/or refracting incident light.
