摘要： In brief, a lighting fixture is provided. The lighting fixture has both a transmitted and reflected light component employing a polymeric material which has an appearance, in varying degrees, of white. The material has internal elements which can be varied to be either highly reflective or permit efficient diffuse transmission of incident light rays. The ratio of reflected to transmitted light and the degree of diffusion are tailored to the application, light source and desired appearance. The material is adapted for providing a selected diffuse transmission component of a total fixture output. The material provides a set diffuse transmission component of greater than 1% and less than 25% where the material is formed by pigmenting a transparent material with a white pigment. The material provides a set diffuse transmission component of greater than 1% and less than 99% where the material is formed by a foamed polymeric material, by an expanded bead material, by blending transparent materials having different refractive indices, or by adding a filler to a polymeric material.

摘要： 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.
