摘要： The present invention provides a light redirecting article for redirecting light toward a target angle, the light redirecting article comprising: an input surface comprising a plurality of light redirecting structures. Each light redirecting structure has (i) a near surface having two slopes, sloping away from normal in one direction as defined by a first inclination base angle β 1 , a second inclination angle β 2 , and a first half apex angle α 2 , for accepting incident illumination over a range of incident angles and (ii) a far surface sloping away from normal, in the opposite direction relative to the input surface, as defined by a second base angle γ 1 and a second half apex angle α 1 . In addition, light redirecting structures has (b) an output surface opposing to the input surface, wherein the near and far surfaces are opposed to each other at an angle (α 1 +α 2 ), and the base angle β 1 is greater than or equal to 90 degrees.
