Abstract

An LED cove light system having a wall piece mounted to a back surface of a cove, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove. A light fixture component is removably attachable at an angle to the wall piece and carries one or more LEDs positioned to project light from the cove out into an adjacent space of a room.

Claims

1. An LED cove light system comprising:

a wall piece mounted to a back surface of a vertical cove wall, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove;

a light fixture component removably attachable to the wall piece and carrying one or more LEDs positioned to project light at a selected angle from the cove toward a ceiling of a room when the wall piece is mounted to a said vertical back surface and the light fixture component is attached to the wall piece; and

wherein the one or more LEDs are further positioned so as to not be visible on a line of sight perpendicular to the vertical cove wall from a point looking toward the front cove wall.

2. The LED cove light system of claim 1 wherein the one or more LEDs comprise a plurality of LEDs mounted in a row adjacent a top edge of a circuit board of said light fixture component but beneath the top surface of the front wall of said cove.

3. The LED cove light system of claim 2 wherein the light fixture component and wall piece are configured to enable removable attachment to one another without the use of tools.

4. The LED cove light system of claim 1 wherein the wall piece has a horizontal groove formed in a front surface thereof and a hook disposed beneath the horizontal groove and wherein the light fixture component has a lip and a hook located beneath the lip, the hook and lip of the light fixture component each being positioned, shaped and dimensioned such that the lip of the light fixture component is insertable into the horizontal groove of the wall piece and the hook of the light fixture component can thereafter come into engagement with the hook of the wall piece to fix the light fixture component in a selected position with respect to the wall piece.

5. The LED cove light system of claim 4 wherein the light fixture component further comprises a circuit board mounting one or more LEDs and a lens component mounted over the circuit board.

6. The LED light system of claim 5 wherein the lens component comprises a radiused segment located over the one or more LEDs.

7. The LED cove light system of claim 5 wherein the one or more LEDs comprise a plurality of LEDs mounted in a row adjacent a top edge of the circuit board.

8. The LED cove light system of claim 7 wherein the row of LEDs is set back from the top edge of the circuit board by a distance in the range of 0.030 to 0.060 inches.

9. The LED cove light system of claim 5 wherein the LED circuit board comprises a planar LED mounting surface disposed at an angle of 20 degrees to the vertical.

10. The LED cove light system of claim 1 wherein the selected angle is 20 degrees.

11. The LED cove light system of claim 1 wherein said light fixture component further comprises a lens and a reflector, the lens being disposed over the plurality of LEDs and the reflector being positioned within the lens and beneath the plurality of LEDs so as to redirect light emanating from the plurality of LEDs out through the lens.

12. The LED light system of claim 11 wherein the lens comprises an arcuate portion positioned over the LEDs and a flat portion extending below the arcuate portion, the arcuate portion having a constant radius.

13. A method of illuminating a first vertical wall positioned opposite a second vertical wall comprising:

constructing a wall piece and configuring the wall piece to be attachable to a surface;

configuring a light fixture component and the wall piece to be removably attachable to one another and positioning a plurality of LEDs in a row in the light fixture component below a top edge of said light fixture component and at an angle selected to project light from the LEDs into an adjacent space;

attaching the wall piece to a horizontal surface in front of the second vertical wall in at a position selected such that, when the light fixture component is attached to the wall piece, the LEDs are positioned to illuminate the first vertical wall and each of the LEDs is spaced at the same selected distance from the first vertical wall; and

attaching the light fixture component to the wall piece.

14. The method of claim 13 wherein the horizontal surface is a horizontal floor surface.

15. The method of claim 13 wherein the horizontal surface is a horizontal ceiling surface.

16. An LED cove light system comprising:

a cove located beneath a ceiling of a room, the cove having a rear vertical wall spaced apart from a front wall;

a wall piece mounted to the rear vertical wall of the cove, the wall piece having a top edge which is at the same height as a top surface of a front wall of the cove;

a light fixture component which is removably attachable to the wall piece and which carries one or more LEDs positioned to project light at a selected angle from the cove toward the ceiling of the room when the wall piece is mounted to the rear vertical wall of the cove and the light fixture component is attached to the wall piece; and

wherein the one or more LEDs are further positioned so as to not be visible on a line of sight perpendicular to the rear vertical wall of the cove from a point looking toward the front wall of the cove.

17. The LED cove light system of claim 16 wherein said light fixture component has a lens and a reflector with the lens being disposed over the one or more LEDs and the reflector being positioned within the lens so as to redirect light emanating from the one or more LEDs out through the lens.

18. The LED cove light system of claim 17 wherein the lens comprises an arcuate portion positioned over the one or more LEDs and a flat portion extending below the arcuate portion, the arcuate portion having a constant radius.
