Louver Assembly

摘要

A generally plano rectangular louvers are capable of being ganged in a stacked tiltable array to enhance light re-direction when titled to follow the solar elevation. Combinations of features and optical characteristic avoid optical artifacts and enhance efficiency of light utilization and manufacturing. Different louvers can be combined in alternative ways in such arrays.

主权项

1) A louver, comprising:
a) a generally rectangular planar support member having; b) an upper surface and a lower surface opposite the upper surface, c) an elongated front side on a side orthogonal to the plane of the upper surface, and an elongated back side opposed to and parallel with the front side, d) a right side on another side that is orthogonal to both the upper surface and the front side, and a left side opposite the front side that is parallel to the right side, e) a light redirecting structure that is at least one of attached to and disposed within the planar support member, the light redirecting structure comprising a plurality of spaced apart light reflective surfaces that terminate at corners, wherein the light reflecting surface thereof extend across the planar support member from the front side to the back side in which each light reflective surface faces the front or back side, f) wherein the light reflective surfaces are operative to increase the width of a main specular re-directed beam of incident light by at least about ±1°.
