<p>An optically redundant light emitting device includes a light transmitting film comprising an array of coupling lightguides extending from a light emitting area defined within the light transmitting film. Each coupling lightguide is bent to form a stacked array of coupling lightguides. A first group of light sources comprising at least one light source is positioned to emit light into the stacked array of coupling lightguides, and a second group of light sources comprising at least one light source is positioned to emit light into the stacked array of coupling lightguides. A first optical path of the light emitted from the first group of light sources overlaps with a second optical path of the light from the second group of light sources in each coupling lightguide.</p>
