PRISMATIC LIGHT LOUVER |
摘要 |
A light transmitting louver for use as a ceiling panel in a luminous ceiling or as a lens in a lighting fixture. The louver has a planar member adapted to be positioned adjacent a light source and a plurality of walls extending from the member on the side opposite the light source to define a symmetrical closed cell system. Within the peripheral extent of each cell and on a surface of the planar member are prisms which extend generally symmetrical to the cell axis and with the cell wall. The individual prisms are asymmetrical in cross-section, i.e., the angular slope of the respective surfaces of each prism is different.
