Sunlight redirecting mirror arrays

摘要

Sunlight redirector (30) incorporates closely proximate mirror arrays (32, 34) having parallel, uniformly spaced, longitudinal mirror segments (38, 44). Prismatic sheet (36) is positioned behind and closely proximate second array (34). Segments (38) extend in first direction (x). Segments (44) extend in second direction (y) perpendicular to direction (x) segments (38, 44)have normal vectors (42, 48). Segments (38) are interconnected for simultaneous pivotal movement (40), such that their normal vectors (42) remain parallel. Segments (44) are interconnected for simultaneous pivotal movement (46), such that their normal vectors (48) remain parallel. Arrays (32, 34) redirect incident light toward sheet (36), which redirects the light into a desired fixed direction, e.g. parallel to the sunlight redirect's normal vectors (50). Segments (38, 44) may have inward and outward segments (60A, 60B) which can be adjustably positioned to maximize redirection of incident sunlight rays in a desired direction.

1. A sunlight redirector, comprising:
a first mirror array having a first plurality of substantially parallel, uniformly spaced, longitudinal mirror segments; a second mirror array having a second plurality of substantially parallel, uniformly spaced, longitudinal mirror segments; and a prismatic sheet; wherein:
the first mirror array is positioned in front of and in close proximity to the second mirror array;the prismatic sheet is positioned behind and in close proximity to the second mirror array;the first plurality of mirror segments extend in a first direction (x); andthe second plurality of mirror segments extend in a second direction (y) substantially perpendicular to the first direction (x).
