ABSTRACT:
An assembly for frontlighting or backlighting a display or other such arrangement requiring frontlighting or backlighting is disclosed herein. The assembly uses a light pipe with a set of specially configured microprisms to rotate the divergent angle of light. The divergent angle rotator is used with a flat collimator assembly for efficient display illuminating with light of a controllable degree of collimation in both dimensions.
