Abstract

The present disclosure is directed to examples of a through wall light fixture. In one embodiment, the through wall light fixture includes a collimated light source, an optic wave guide, wherein the collimated light source is coupled to a first end of the optic wave guide to be located closer to an interior side of a wall, and a light distribution element coupled to a second end of the optic wave guide to be located closer to an exterior side of the wall.

Claims (36)

1. A through wall light fixture, comprising:

a collimated light source;

an optic wave guide, wherein the collimated light source is coupled to a first end of the optic wave guide to be located closer to an interior side of a wall; and

a light distribution element coupled to a second end of the optic wave guide to be located closer to an exterior side of the wall.

2. The through wall light fixture of claim 1 , wherein a length of the through wall light fixture is greater than a thickness of the wall.

3. The through wall light fixture of claim 1 , further comprising:

a housing, wherein the housing comprises mechanical features to connect to the interior side of the wall and enclose the collimated light source that is located closer to the interior side of the wall.

4. The through wall light fixture of claim 1 , wherein the collimated light source comprises:

a collimation optic; and

a light source coupled to the collimation optic.

5. The through wall light fixture of claim 4 , wherein the collimation optic comprises a total internal reflection lens.

6. The through wall light fixture of claim 4 , wherein the collimation optic comprises a metallized reflector.

7. The through wall light fixture of claim 4 , wherein the light source comprises a light emitting diode (LED).

8. The through wall light fixture of claim 1 , wherein collimated light source comprises a laser.

9. The through wall light fixture of claim 1 , wherein the optic wave guide comprises a cylindrical shape.

10. The through wall light fixture of claim 1 , wherein the optic wave guide comprises a hollow pipe with a reflective inner surface.

11. The through wall light fixture of claim 1 , wherein the optic wave guide comprise a clear plastic light pipe.

12. The through wall light fixture of claim 1 , wherein the optic wave guide comprise an optical fiber.

13. The through wall light fixture of claim 1 , wherein the light distribution element comprises at least one of: a total internal reflection optical element, a refractive optical element, or a metalized optical element.

14. The through wall light fixture of claim 1 , wherein the light distribution element comprises compound optics.

15. The through wall light fixture of claim 14 , wherein the compound optics, comprises:

a first optical feature to move a vertical peak intensity of a light emitted by the light source;

a second optical feature to split the light emitted by the lights source into to horizontal beams; and

a third optical feature to provide a uniform light intensity along a horizontal plane.

16. The through wall light fixture of claim 15 , wherein the first optical feature comprises a textured outer lens.

17. The through wall light fixture of claim 15 , wherein the second optical feature comprises an opposing pair of total internal reflection lenses.

18. The through wall light fixture of claim 16 , wherein the third optical feature comprises a textured inner lens.

19. A through wall light fixture, comprising:

a means for emitting a collimated light;

a means for moving the collimated light, wherein the means for emitting the collimated light is coupled to a first end of the means for moving light to be located closer to an interior side of a wall; and

a means for distributing light coupled to a second end of the means for moving light to be located closer to an exterior side of the wall.

20. A method for installing a through wall light fixture, comprising:

drilling a hole through an interior side of a wall, wherein the hole has a diameter approximately equal to the diameter of the through wall light fixture;

inserting the through wall light fixture through the hole such that a light distribution element coupled to an outer end of an optic waveguide protrudes through an exterior side of the wall;

electrically connecting a light source of the through wall light fixture to a power source and a controller; and

enclosing a collimation optic that contains the light source, the power source, and the controller on the interior side of the wall via a housing that is coupled to the interior side of the wall.
