Abstract:
A light diffusing component is disclosed. The light diffusing component comprises a substrate, such as glass, having a frontside, a backside spaced apart from the frontside, and an edge configured to receive a light source. The glass sheet includes at least one scattering layer having a plurality of light scattering centers etched into at least a portion of the frontside of the glass sheet. The scattering centers have an increased density as the distance from the edge increases and the scattering centers are randomly distributed in size and smaller than about 200 μm. Also disclosed is a method of manufacturing a light diffusing component comprising masking a substrate, such as a glass sheet, and etching the substrate such that the density of the resulting scattering centers increased as the distance from the light source increases.
