Abstract
Embodiments of the invention include luminaires with a large-scale prism. In some embodiments, a large-scale prism can be any prism with a base having the smallest dimension greater than one half of an inch. In some embodiments, a large-scale prism can be any prism with a base having the smallest dimension between two and four inches. At these large-scales, the geometry of the individual prism can be easily appreciated through casual observation. Use of large-scale prisms can provide a light without high angle glare.
Claims24
A luminaire comprising:
- a light source;
- a large-scale prism having a base surface and at least one other surface, wherein the large-scale prism is positioned near the light source such that light from the light source passes through the base surface, and wherein the large-scale prism luminaire comprises an air gap disposed between the large-scale prism and the light source;
- and
- an attachment mechanism that attaches the luminaire to a ceiling.

A luminaire comprising:
- a luminaire body having a length and a width;
- a plurality of LEDs disposed within the luminaire body;
- a large-scale prism having a base that is coupled with the luminaire body;
- and
- a patterning lens disposed between the plurality of LEDs and the single large-scale prism with an air gap between the patterning lens and the single large-scale prism.
2 more elements
A luminaire comprising:
- a first large-scale prism comprising at least three faces;
- a second large-scale prism comprising at least three faces;
- a double sided mirror disposed between and coupled with one face of the first large-scale prism and one face of the second large-scale prism;
- and
- an optical element optically coupled with a face of the first large-scale prism and not optically coupled with a face of the second large-scale prism.
2 more elements
A luminaire comprising:
- a luminaire body having a length and a width;
- a plurality of LEDs disposed within the luminaire body;
- a solid of optical material having a cross-sectional base that is coupled with the luminaire body, wherein the solid is non-patterned on a majority of its faces;
- and
- a patterning lens disposed between the plurality of LEDs and the solid with an air gap between the patterning lens and the solid.
