The present invention relates to a light scrambling system that includes a substrate and a plurality of light pipes. The substrate includes a first surface and a second surface opposite the first surface. Each of the plurality of light pipes includes a first end on the first surface of the substrate, a second end on the second surface of the substrate, and at least one inside surface formed by a refractive index boundary. The light input is received by the first end at a plurality of input angles, and the light output is transmitted at the second end at a plurality of output angles. At least a portion of the input angles are different from at least a portion of the output angles, thereby scrambling the light received by the first ends of the light pipes and transmitted by the second ends of the light pipes.
