A light fixture including a louver assembled from blades formed of thin metal strips. The blades each have separate parabolic lower sidewalls and upper sidewalls. The parabolic upper sidewalls terminate in edge strips which overlap to close the blades when the blades are nested to form the louver. Nesting of the blades forces the sidewalls together against a resilient bias, the bias tending to rigidify the louver after assembly.

Light fixture and louver construction

A louver construction comprising a grid formed of cubes molded unitarily with a flange extending around the periphery of the grid. The cubes include a border row making up the periphery of the grid. The cubes in the border row have different dimensions than those inside them in the grid. The flange may vary in width but the outside dimensions of the louver remain the same. As a result, the same size louver grids will fit different size light box openings.
