Abstract

A skylight with a sunlight pivot is provided. The skylight includes an external cover, a light channel, and a sunlight pivot disposed between the cover and the light channel. The sunlight pivot may include a periphery, a plurality of struts, and first and second prisms connected to at least two of these struts. The first and second prisms may define a void between them. The first prism has a cross-section configured to redirect light incident upon the exterior of the pivot to increase the amount of light passing into the light channel. The second prism is configured with a cross-section configured to redirect light incident upon the exterior of the pivot to decrease the amount of light passing through the periphery.

First claim

The invention claimed is:

1. A skylight, comprising:
An external cover;
A light channel depending downwardly beneath said external cover;
A sunlight pivot, said sunlight pivot disposed beneath said external cover and above said light channel, said sunlight pivot including:
A periphery;
A plurality of struts, said plurality of struts extending from about said periphery, upwardly, and inwardly;
First and second prisms, said first and second prisms defining a first void therebetween and carried by at least two of said plurality of struts; and
Said first prism defining a first cross-section and said second prism defining a second cross-section, said first cross-section different from said second cross-section.

2. The skylight of claim 1 , in which said first prism extends in a first arc.

3. The skylight of claim 2 , in which said second prism extends in a second arc, said second arc shorter than said first arc.

4. The skylight of claim 1 , wherein said first prism terminates at an aperture that is devoid of refraction.

5. The skylight of claim 1 , wherein said first prism is parallel to said periphery.

6. The skylight of claim 1 , in which said periphery is curvilinear.

7. The skylight of claim 1 , further including a third prism, said third prism residing adjacent to said first prism and defining a second void therebetween.

8. The skylight of claim 1 , further including a fourth prism, said fourth prism residing adjacent to said second prism and defining a third void therebetween.

9. The skylight of claim 7 , in which said first and third prisms reside in a single first conical frustum.

10. The skylight of claim 8 , in which said second and fourth prisms reside in a single second conical frustum.

11. The skylight of claim 10 , in which said first conical frustum is nonparallel to said second conical frustum.

12. A skylight, comprising:
An external cover;
A light channel below said external cover;
A sunlight pivot, said sunlight pivot disposed between said external cover and said light channel, said sunlight pivot including:
A periphery;
A plurality of struts, said plurality of struts extending upwardly and inwardly from proximate to said periphery;
First and second prisms, said first and second prisms defining a void therebetween and connected to at least two of said plurality of struts; and
Said first prism defining a first cross-section configured to redirect light incident upon the exterior of the pivot to increase the amount of light passing through the periphery; and
Said second prism defining a second cross-section configured to redirect light incident upon the exterior of the pivot to decrease the amount of light passing through the periphery.

13. The skylight of claim 12 , in which said first prism is parallel to said periphery.

14. The skylight of claim 12 , in which said first and second prisms are parallel.

15. The skylight of claim 12 , in which said first and second prisms are curvilinear.

16. The skylight of claim 12 , wherein said first cross-section and said second cross-section are each constant along their respective lengths.

17. The skylight of claim 12 , in which said first and second prisms each are triangular in cross-section, the hypotenuses of said cross-sections facing outwardly from said pivot.

18. A skylight, comprising:
An external cover;
A light channel residing below said external cover;
A sunlight pivot, said sunlight pivot disposed between said external cover and said light channel, said sunlight pivot including:
A periphery and apex, said periphery residing below said apex;
A plurality of struts, each of said plurality of struts extending proximate from said apex toward said periphery;
A plurality of first prisms,
each such first prism having the same first cross-section configured to refract light incident upon the exterior of the pivot to increase the amount of light passing into the skylight;
defining a void between any two of each such first prisms;

A plurality of second prisms,
each such second prism having the same second cross-section configured to refract light incident upon the exterior of the pivot to decrease the amount of light passing into the skylight;
defining a void between any two of each such second prisms; and

Said plurality of first prisms and said plurality of second prisms carried by at least two of said plurality of struts.

19. The skylight of claim 18 , wherein the plurality of first prisms resides in a first conical frustum and the plurality of second prisms resides in a second conical frustum, the first and second conical frustums being nonproportional.

20. The skylight of claim 18 , wherein the first prisms are parallel to the second prisms.
