A light transmitting louver comprising:
- a louver wherein:
- a) a first curved element of the louver has a first end and a second end,
- wherein the first curved element is composed of a plastic or metal;
- b) a second element of the louver has a first end and a second end,
- wherein the first end of the second element connects with the second end of the first curved element, and
- wherein the second element includes a diffuser;
- and
- c) a third curved element of the louver has a first end and a second end,
- wherein the second end of the second element connects with the first end of the third curved element, and
- wherein the third curved element includes a reflective surface,
- wherein the first curved element, the second element, and the third curved element connect such that the louver forms an airfoil-shaped body.
A light transmitting louver comprising:
- a louver wherein:
- a) a first curved element of the louver has a first end and a second end,
- wherein the first curved element is composed of a plastic or metal, and
- wherein at least a portion of a surface of the first curved element includes a reflective surface;
- and
- b) a second curved element of the louver has a first end and a second end,
- wherein the first end of the second curved element connects with the second end of the first curved element, and
- wherein the second curved element includes a diffuser,
- wherein the first curved element and the second element connect such that the louver forms an airfoil-shaped body.
A light shelf comprising:
- at least one anchor bracket suitable for attachment to a building structure;
- at least one support beam attached to the anchor bracket;
- and
- a plurality of light transmitting airfoil-shaped louvers each supported and positioned by the support beam at a preselected fixed profile angle,
- wherein each of the louvers includes a diffuser and a reflective surface.
