Abstract
A skylight sunlight redirector is provided with ridges, grooves, and/or prisms that control light transmitted through the redirector as incident sunlight angle changes throughout the day.
Claims19
A skylight sunlight redirector, comprising:
- A light transmitting body;
- The light transmitting body defining a center, a periphery, an equatorial side and an opposing polar side, and opposing East and West sides;
- The light transmitting body defining a plurality of ridges, each ridge:
- (a) Disposed within the periphery;
- (b) Defining a length with a first end and an opposing second end, the length extending circumferentially around a majority but not all of the body;
- (c) Disposed in a first arc relative to the periphery;
- and
- (d) Defining a cross-section, the cross-section continually varying along the length from the first end to the second end;
- wherein at least one of the ridges is configured to redirect light incident upon the body from the East and West sides away from the center;
- and
- wherein the first end is disposed on the East side, the second end is disposed on the West side, and the ridges extend through the equatorial side.

A skylight sunlight redirector, comprising:
- A light transmitting body, the light transmitting body having a first surface and an opposite second surface;
- The light transmitting body defining a center axis, an equatorial side and an opposing polar side, and opposing East and West sides;
- The light transmitting body defining a first cross-section, the first cross-section being at least partially curvilinear;
- The first surface carrying a plurality of grooves, each groove:
- (a) Being disposed within the at least partially curvilinear first cross-section;
- (b) Extending circumferentially around the body from a first end to an opposite second end, with a transparent zone disposed between the first end and the second end;
- (c) Defining a second cross-section, the second cross-section continually varying from the first end to the second end;
- and
- (d) Defining an arc relative to the center axis, the arc residing in a plane non-perpendicular to the center axis;
- wherein at least one of the grooves is configured to redirect light incident upon the body from the East and West sides away from the center axis;
- and
- wherein the first end is disposed on the East side, the second end is disposed on the West side, and the grooves extend through the equatorial side.
9 more elements
A skylight sunlight redirector, comprising:
- A light transmitting convexity, the convexity comprising a center, a periphery, an equatorial side and an opposing polar side, and opposing East and West sides;
- A plurality of prisms carried by the convexity;
- Each prism:
- (a) Extending around the center less than the entirety of the convexity from a first end to an opposite second end;
- (b) Defining a cross-section, the cross-section continually varying from the first end to the second end;
- (c) Arcuate relative to the center;
- Wherein at least one of the prisms is configured to redirect light incident upon the convexity from the East and West sides away from the center;
- and
- Wherein at least one of the prisms is configured to redirect light incident upon the convexity from the equatorial side toward the convexity;
- and
- Wherein the first end is disposed on the East side, the second end is disposed on the West side, and the prisms extend through the equatorial side.
