SUNLIGHT-REFLECTING BLINDS
First Claim
1. A blind for installation between an inner environment and an outer environment where light originates, the blind comprising:
- slats substantially forming a vertically periodic arrangement, each one of the slats extending in a substantially horizontal axis and comprising;
an upper surface having a normal oriented both upwardly and toward the outer environment, the upper surface having a coating that provides specular reflection, anda lower surface having a normal oriented both downwardly and toward any one of the outer environment and the inner environment, the lower surface having a coating that provides specular reflection,the upper surface having a lower edge, wherein the upper surface and the lower surface of a given slat are joined at an apex near the lower edge of the upper surface.

Abstract
There is described a blind for installation between an inner environment and an outer environment where light originates. The blind comprises slats substantially forming a vertically periodic arrangement. Each one of the slats extends in a substantially horizontal axis, and comprises an upper surface and a lower surface. The upper surface has a normal oriented both upwardly and toward the outer environment, and comprises a coating providing specular reflection. The lower surface has reflection normal oriented both downwardly and toward any one of the outer environment and the inner environment, and comprises a coating providing specular reflection. The upper surface and the lower surface of a given slat are joined at an apex pointing toward the outer environment.

11. A blind for installation close to an interface between an inner environment and an outer environment where light originates, the light having an inclination with respect to the horizontal, the blind comprising:
-
slats forming a vertically periodic arrangement, each one of the slats extending in a substantially horizontal axis and comprising an upper surface and a lower surface, an angle holding cradle for maintaining a constant angle of the upper surface, wherein the constant angle, together with a period of the periodic arrangement, defines high and low inclination thresholds, wherein the constant angle is set such that; when inclination of the light is above the high inclination threshold, the light is substantially totally outwardly reflected by the upper surface of the slats; when inclination of the light is below the low inclination threshold, the light partially penetrates directly in the inner environment and the remaining portion of the light is inwardly reflected by at least the first one of;
the upper surface and the lower surface; andwhen inclination of the light is between the high inclination threshold and the low inclination threshold, the light partially penetrates directly into the inner environment, and is partially reflected by a double reflection on both the upper surface and the inner surface. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
