  • Edge-lit luminaire having prismatic optical control
    Patent number: 6767106
    Abstract: An edge-lit luminaire includes a panel formed of a transparent material. The panel includes first and second opposing surfaces. At least one edge light source is positioned proximate to the panel. A plurality of prismatic reflective/refractive elements is spaced apart on a predefined pattern on the second surface. The plurality of prismatic reflective/refractive elements have a predefined contour for accurate ray direction control. The predefined pattern on the second surface includes predefined gradient spacing and size variables of the prismatic reflective/refractive elements for providing uniform ray emission across the panel. The plurality of prismatic reflective/refractive elements have a predefined relative spacing of the prismatic reflective/refractive elements based upon a position relative to the light source. Also the predefined relative size of each of the prismatic reflective/refractive elements can be based upon its position relative to the light source.
