Abstract

The present disclosure provides a light fixture attached to a wall or a ceiling to illuminate at least a portion of the ceiling. The light fixture can include a light source enclosed within the light fixture and configured to emanate light directionally away from the wall. The light fixture can include a protrusion. The protrusion can extend away from and below the light source. The protrusion can include a bent end that is bent upwards to direct light at a predetermined angle towards a ceiling. The light fixture can include an optic attached above the light source and extending above and externally towards the bent end of the protrusion. The optic can be configured to direct a portion of light towards the bent end.

Claims

1. A system to illuminate at least a portion of a ceiling, comprising:

a light fixture, supported at a wall or a ceiling, comprising a light source enclosed within the light fixture and configured to emanate light directionally away from the wall towards at least a portion of the ceiling;

a protrusion of the light fixture extending away from and below the light source, wherein a bent end of the protrusion is bent upwards to direct light at a predetermined angle towards the ceiling, wherein a first end of the protrusion is positioned at the light source, and the bent end of the protrusion is opposite the first end of the protrusion; and

an optic attached above the light source and extending above and externally towards the bent end of the protrusion, wherein a first portion of the optic at the first end of the protrusion is thicker than a second portion of the optic at the bent end of the protrusion, and the optic is configured to direct a portion of light towards the bent end.

2. The system of claim 1, wherein the bent end directs the light towards the ceiling at the predetermined angle.

3. The system of claim 1, wherein the predetermined angle of the bent end and the optic are configured to spread light across at least the portion of the ceiling a predetermined distance away from the light fixture.

4. The system of claim 1, comprising a gap between an end of the optic and the bent end.

5. The system of claim 1, wherein an end of the optic meets the bent end.

6. The system of claim 1, wherein the light fixture is attached to the wall or the ceiling and extends perpendicular from the wall and parallel from the ceiling.

7. The system of claim 1, wherein the light source comprises a linear light source having a plurality of light emitting diodes (LEDs).

8. The system of claim 1, wherein the light source comprises a linear light source having a plurality of light emitting diodes (LEDs), and the optic provides a light mixing chamber configured to mix light emitted by the plurality of LEDs.

9. The system of claim 1, wherein the optic is formed from a translucent acrylic.

10. A method of illuminating a ceiling, comprising:

providing a light fixture at a wall or a ceiling, the light fixture comprising a light source enclosed within the light fixture and configured to emanate light directionally away from the wall, wherein the light fixture includes;

a protrusion of the light fixture extending away from and below the light source, wherein a bent end of the protrusion is bent upwards to direct light at a predetermined angle towards the ceiling, wherein a first end of the protrusion is positioned at the light source, and the bent end of the protrusion is opposite the first end of the protrusion; and

an optic attached above the light source and extending above and externally towards the bent end of the protrusion, wherein a first portion of the optic at the first end of the protrusion is thicker than a second portion of the optic at the bent end of the protrusion, and the optic is configured to direct a portion of light towards the bent end.

11. The method of claim 10, wherein the bent end directs the light towards the ceiling at the predetermined angle.

12. The method of claim 10, wherein the predetermined angle of the bent end and the optic are configured to direct a spread of light across the ceiling a predetermined distance from away from the light fixture.

13. The method of claim 10, wherein the light fixture comprises a gap between the optic and the bent end.

14. The method of claim 10, wherein the optic meets the bent end.

15. The method of claim 10, comprising attaching the light fixture to the wall such that the light fixture extends perpendicular from the wall and parallel from the ceiling.

16. The method of claim 10, wherein the light source comprises a linear light source having a plurality of light emitting diodes (LEDs).

17. A method of illuminating a ceiling, comprising:

emanating, by a linear light source of a light fixture attached to a wall or a ceiling, light;

directing, by an optic attached above the linear light source and extending above and externally towards a bent end of a protrusion of the light fixture extending away from and below the linear light source, a portion of the light towards the bent end, wherein a first end of the protrusion is positioned at the linear light source, the bent end of the protrusion is opposite the first end of the protrusion, and a first portion of the optic at the first end of the protrusion is thicker than a second portion of the optic at the bent end of the protrusion; and

projecting, by the bent end, the directed light at a predetermined angle towards the ceiling.

18. The method of claim 17, wherein the linear light source comprises a plurality of light emitting diodes (LEDs), and the optic provides a light mixing chamber configured to mix light emitted by the plurality of LEDs.

19. The method of claim 17, wherein the optic comprises an asymmetric optic formed from translucent acrylic.
