Abstract:
A transparent base panel has embedded therein a series of uniformly, sized, shaped and spaced louvers that extend outwardly from the base panel at an angle , to optimize light flowing in a direction from an inner surface toward an outer surface while minimizing an amount of light flowing from the outer surface to the inner surface. This louvered screen has application in making outdoor illuminated signs more readable, in screening sunlight out of a compartment such as a room, and in deflecting and/or tinting light from a direct or indirect lighting source.
