Abstract:
     The invention discloses the system and method for improving asymmetric projection lighting, which comprises a light source, a lens for projecting the image to the first surface, an optical path extending from the illuminating source to the lens, an optical valve arranged on the optical path, a non-symmetroid element arranged on the optical path between the illuminating source and the light valve. The non-symmetroid unit can increase the collection efficiency and the uniformity of homogeneity for the illumination light, reaching the goal of increasing total collection efficiency of the optical system.
