Abstract:
An edge-lit luminaire comprising:a panel formed of a transparent material; said panel including first and second opposing surfaces; at least one edge light source positioned proximate to said panel; and a plurality of prismatic reflective/refractive elements integrally formed with said panel and spaced apart on a predefined pattern on said second surface; each of said prismatic reflective/refractive elements extending from said second surface and providing a reflective function and a refractive function and each of said prismatic reflective/refractive elements being precisely contoured elements providing controlled reflected light rays at a multitude of predefined angles; said predefined pattern of said spaced apart plurality of prismatic reflective/refractive elements and a size of each said plurality of prismatic reflective/refractive elements being selectively provided relative to said at least one edge light source for panel controlled illumination.
