ABSTRACT:
A transparent prismatic low luminance lighting panel having on the outer or light-emissive surface thereof a plurality of refracting prismatic elements in the form of partially spherical domes overlapping one another and arranged in orthogonal rows and columns parallel to the length and width of the panel. The upper or light-incident surface of the panel has integral therewith a plurality of raised square-shape portions at positions opposite the square bases of the prismatic elements, or a plurality of longitudinal raised portions at positions opposite to the columns of the square bases. The upper surfaces of the raised portions are covered by a coating of an opaque material which stops and reflects any undesirable luminous rays falling thereon.
