ABSTRACT:
A compact, light weight, efficient and cost-effective illumination system for optical displays is disclosed. The illumination system is capable of producing a self-luminous light beam of selected cross-section and spatial distribution in terms of intensity and angle. The illumination system can efficiently couple light from light sources having wide variety of sizes and shapes into light valves of various shapes and sizes. The illumination system includes a light recovery system or a polarization conversion system or a suitable combination of the foregoing.
