Abstract

An edge-lit waveguide and macro optic hybrid structure includes a waveguide segment having a light receiving surface and a light emitting surface. The light receiving surface and the light emitting surface are on opposite sides of the waveguide segment. The edge-lit waveguide and macro optic hybrid structure also includes a macro optic segment integrally formed with the waveguide segment. A light emitting surface of the macro optic segment extends out beyond the waveguide segment on a side of the waveguide segment.

First claim

What is claimed is:

1. An edge-lit waveguide and macro optic hybrid assembly for a lighting fixture, comprising:
a waveguide having a light receiving surface and a light emitting surface; and
a macro optic structure comprising a first wing segment and a second wing segment, wherein a light emitting surface of the macro optic structure that is between the first wing segment and a second wing segment faces the light receiving surface of the waveguide, wherein the first wing segment extends out beyond the waveguide on a first side of the waveguide, wherein a light emitting surface of the first wing segment is spaced from a first broad light emitting surface of the waveguide and forms an acute angle with the first broad light emitting surface of the waveguide, wherein the second wing segment extends out beyond the waveguide on a second side of the waveguide, and wherein a light emitting surface of the second wing segment is spaced from a second broad light emitting surface of the waveguide and forms a second acute angle with the second broad light emitting surface of the waveguide.

2. The hybrid assembly of claim 1 , wherein the macro optic structure further comprises a middle segment between the first wing segment and the second wing segment and wherein the light emitting surface of the macro optic structure is in the middle segment.

3. The hybrid assembly of claim 1 , wherein the light receiving surface and the light emitting surface of the waveguide are on opposite ends of the waveguide from each other, wherein the light emitting surface of the waveguide emits a first portion of a light from a light source toward an area below the waveguide, wherein the light emitting surface of the first wing segment emits a second portion of the light toward the area below the waveguide, and wherein the light emitting surface of the second wing segment emits a third portion of the light toward the area below the waveguide.

4. The hybrid assembly of claim 3 , wherein the first wing segment comprises a first light reflecting surface to reflect the second portion of the light toward the light emitting surface of the first wing segment and wherein the second wing segment comprises a second light reflecting surface to reflect the third portion of the light toward the light emitting surface of the second wing segment.

5. The hybrid assembly of claim 1 , wherein the macro optic structure comprises an optical pattern on the light emitting surface of the macro optic structure.

6. The hybrid assembly of claim 1 , wherein the light emitting surface of the macro optic structure and the light receiving surface of the waveguide partially bound an air gap.

7. The hybrid assembly of claim 1 , wherein the first broad light emitting surface and the second broad light emitting surface are on opposite sides of the waveguide.

8. The hybrid assembly of claim 1 , wherein the waveguide and the macro optic structure are made from acrylic.
