Patent abstract

Light emitters are made of one or more cladded flat optical fibers having opposite flat sides and disruptions along at least a portion of the length of the fibers to cause light entering at least one end to be emitted from at least one side. The ends of the flat optical fibers may have substantially the same thickness as a light source and a width substantially equal to or substantially greater than the width of the light source for ease of optically coupling one or more such light sources to the flat optical fiber ends.
