Abstract

A device for providing light including: a housing; an array of a plurality of LED lights mounted to the housing, wherein, when active, each LED emits a highest intensity beam of light along a primary axis and emits a lower intensity beam of light along a secondary axis; a lens mounted to the housing, the lens including an optic element corresponding to each of the plurality of LED lights, each optic element intersected by the primary axis of the corresponding LED light; and a translucent edge-light diffusing layer located between two or more of the plurality of LED lights, the edge diffusing layer is not intersected by the primary axis and is intersected by the secondary axis of the LED lights.

Claims

1. A device for providing light comprising:

an array of a plurality of LED lights, wherein, when active, each of the plurality of LED lights emits a highest intensity beam of light along a primary axis and emits a lower intensity beam of light along a secondary axis; and

a translucent edge-light diffusing layer located between two or more of the plurality of LED lights, the edge-light diffusing layer is not intersected by the primary axis and is intersected by the secondary axis of the two or more of the plurality of LED lights.

2. The device for providing light of claim 1, further comprising a lens mounted to a housing, the lens including an optic element corresponding to each of the plurality of LED lights, each optic element intersected by the primary axis of a corresponding LED light of the plurality of LED lights.

3. The device for providing light of claim 2, wherein each optic element includes a diffusive surface.

4. The device for providing light of claim 3, wherein each diffusive surface includes a coating including suspended diffusive particles.

5. The device for providing light of claim 1, wherein the edge-light diffusing layer is translucent plastic.

6. The device for providing light of claim 1, wherein the device further includes a reflective layer between the housing and the edge-light diffusing layer.

7. The device for providing light of claim 1, wherein the primary axis of each LED light of the plurality of LED lights is parallel to the others.

8. The device for providing light of claim 1, wherein a thickness of the edge-light diffusing layer equals a thickness of the plurality of LED lights.

9. The device for providing light of claim 1, wherein the edge-light diffusing layer extends above the light emitting-surface of the LED lights along the direction of the primary axis.

10. A device for providing light comprising:

a plurality of LED lights, wherein, when active, each of the plurality of LED lights emits a higher intensity beam of light along a primary axis and emits a lower intensity beam of light along a secondary axis; and

a translucent edge-light diffusing layer located between two or more of the plurality of LED lights, the edge-light diffusing layer is not intersected by the primary axis and is intersected by the secondary axis of the two or more of the plurality of LED lights.

11. The device for providing light of claim 10, wherein each of the plurality of LED lights emits a highest intensity beam of light along the primary axis.

12. The device for providing light of claim 10, further comprising a lens mounted to a housing, the lens including an optic element corresponding to each of the plurality of LED lights, each optic element intersected by the primary axis of a corresponding LED light of the plurality of LED lights.

13. The device for providing light of claim 12, wherein each optic element includes a diffusive surface.

14. The device for providing light of claim 13, wherein each diffusive surface includes a coating including suspended diffusive particles.

15. The device for providing light of claim 10, wherein the edge-light diffusing layer is translucent plastic.

16. The device for providing light of claim 10, wherein the device further includes a reflective layer between the housing and the edge-light diffusing layer.

17. The device for providing light of claim 10, wherein the primary axis of each LED light of the plurality of LED lights is parallel to the others.

18. The device for providing light of claim 10, wherein a thickness of the edge-light diffusing layer equals a thickness of the plurality of LED lights.

19. The device for providing light of claim 10, wherein the edge-light diffusing layer extends above the light emitting-surface of the LED lights along the direction of the primary axis.
