Lighting system cover including AR-coated textured glass
First Claim
1. A light emitting diode (LED) lighting system comprising:
- a glass substrate disposed over a plurality of LEDs,a first anti-reflective (AR) coating provided directly or indirectly on a first major surface of the glass substrate,wherein a second major surface of the glass substrate is prismatically textured to increase transmission of light at at least some viewing angles greater than about 45 degrees from normal, the second major surface being opposite the first major surface,wherein the glass substrate is arranged such that the first major surface thereof is closer than the second major surface thereof to the plurality of LEDs.

Abstract
Certain example embodiments relate to lighting system covers that include AR-coated textured glass, and/or methods of making the same. In certain example embodiments, 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.
