Abstract
Certain examples relate to lighting system covers that include AR-coated textured glass, and/or methods of making the same. In certain examples, at least one light source is provided proximate to a cover comprising a glass substrate. The glass substrate includes an anti-reflective (AR) coating on the surface that is closer to the at least one light source, and the glass substrate is textured (e.g., such that it is substantially prismatic in texture) on the surface opposite the AR-coated surface. The surface of the glass substrate on which the AR coating is formed may be a flat, irregular, or textured matte. An optional AR coating also may be formed on the textured surface of the glass substrate.
