1. A window blind solar energy management system comprising:
- a first louver positioned adjacent a window;
a second louver positioned adjacent said first louver, wherein said first louver is oriented with respect to said second louver to reflect light coming through said window toward said second louver;
said second louver further comprising a solar energy redirection assembly oriented to receive reflected light from said first louver, said solar energy redirection assembly further comprising;
a light reflection portion configured to reflect light from said first louver away from said window and into a room to which said window is attached;
a heat absorption and radiation portion configured to absorb heat from reflected light from said first louver, and to radiate heat into said room; and
a light rejection portion configured to reflect light from said first louver outward through said window; and
said second louver further comprising a mirror adjacent said solar energy redirection assembly, wherein said heat absorption and radiation portion is thermally insulated from said mirror.

Abstract
Disclosed is a window blind solar energy management system for capturing solar energy to manage illumination and temperature within a defined space. Blinds comprising curved louvers are hung from the internal frame of a window, each louver having a concave, highly reflecting specular mirrored surface that focuses incoming solar beam radiation onto a thin area on the back of the adjacent louver. The angle of the louvers is adjusted by an integral automatic controller so that the thin strip of light can be focused on one or two of three regions on the back of the adjacent louver which are designed to either reflect, absorb, or reject the incoming light.

19. A window blind solar energy management system comprising:
-
a first louver positioned adjacent a window; a second louver positioned adjacent said first louver, said second louver having a first side facing said first louver and a second side facing away from said first louver, wherein said first louver is oriented with respect to said second louver to reflect light coming through said window toward said second louver; said second louver further comprising a solar energy redirection assembly oriented to receive reflected light from said first louver, said solar energy redirection assembly further comprising; a light reflection portion configured to reflect light from said first louver away from said window and into a room to which said window is attached; a heat absorption and radiation portion configured to absorb heat from reflected light from said first louver, and to radiate heat into said room; a light rejection portion configured to reflect light from said first louver outward through said window; and one or more openings extending through said second louver through which light reflected from said first louver may pass to impact at least a portion of said solar energy redirection assembly that is positioned on said second side of said second louver. - View Dependent Claims (20, 21, 22, 23)
