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

a wall piece mounted to the rear portion of the cove to which a light fixture component is removably attachable;

a light fixture component configured to removably attach to the wall piece and comprising (a) a circuit board mounting a plurality of LEDs, (b) a light transmissive cover positioned over the LEDs, and (c) a reflector positioned within the light transmissive cover;

wherein the wall piece and light fixture component are configured to interlock such that when the light fixture component is attached to the wall piece, the circuit board is fixed in position to project light from the cove toward the ceiling of the room at a pre-selected angle; and

wherein the reflector is positioned beneath the plurality of LEDs so as to redirect light emanating from the plurality of LEDs out through the light transmissive cover so as to thereby increase the amount of light exiting the cove.

2. The LED cove light system of claim 1 wherein the wall piece does not include any electrical connectors.

3. The LED cove light system of claim 1 wherein the light transmissive cover is configured to shape the light output of the plurality of LEDs.

4. The LED cove light system of claim 1 wherein the light fixture component is configured and positioned to enable 85% or more of the light generated by the LEDs to exit the cove.

5. The LED cove light system of claim 1 wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a planar portion extending beneath the arcuate portion and over and parallel to a surface of the printed circuit board.

6. An LED cove light system comprising:

an architectural cove constructed during a construction phase of a structure and located beneath a ceiling of a room, the architectural cove having a rear portion spaced apart from a front wall;

a wall piece mounted to the rear portion of the architectural cove; and

a light fixture component configured to removably attach to the wall piece and comprising (a) a circuit board mounting a plurality of LEDs and (b) a light transmissive cover positioned over the LEDs, and wherein, when the light fixture component is attached to the wall piece, the circuit board is fixed in position to project light from the architectural cove toward the ceiling of the room at a pre-selected fixed angle.

7. The LED cove light system of claim 6 wherein a reflector is positioned within the light transmissive cover and beneath the plurality of LEDs so as to redirect light emanating from the plurality of LEDs out through the light transmissive cover so as to increase the amount of light exiting the cove.

8. The LED cove light system of claim 6 wherein the light transmissive cover is configured to shape the light output of the plurality of LEDs.

9. The LED cove light system of claim 6 wherein the light fixture component is configured and positioned to enable 85% or more of the light generated by the LEDs to exit the architectural cove.

10. The LED cove light system of clam 6 wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a planar portion extending beneath the arcuate portion and over and parallel to a surface the printed circuit board.

11. An LED cove light system comprising:

a cove located beneath a ceiling of a room;

a wall piece mounted to the a rear portion of the cove; and

a light fixture component attachable to the wall piece and comprising a circuit board mounting a plurality of LEDs, the light fixture component, LEDs, and mounting piece being configured and positioned such that 85% or more of the light generated by the LEDs exits the cove when the wall piece is mounted to the rear portion of the cove and the light fixture component is attached to the wall piece.

12. The LED cove light system of claim 11 wherein the light fixture component further comprises a light transmissive cover and a reflector, the light transmissive cover being disposed over the plurality of LEDs and the reflector being positioned within the light transmissive cover so as to redirect light emanating from the plurality of LEDs out through the light transmissive cover so as to increase the amount of light exiting the cove.

13. The LED light system of claim 12 wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a planar portion extending beneath the arcuate portion and over the printed circuit board, the arcuate portion having a constant radius.

14. The LED cove light system of claim 11 wherein the wall piece does not include any electrical connectors.

15. The cove lighting system of claim 11 wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a planar portion extending beneath the arcuate portion and over and parallel to a surface of the printed circuit board.

16. An LED cove light system comprising:

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

a wall piece mounted to the rear portion of the cove;

a light fixture component configured to removably attach to the wall piece and comprising (a) a circuit board mounting a plurality of LEDs, (b) a light transmissive cover positioned over the LEDs, and (c) a reflector positioned within the light transmissive cover;

an electrical connector for conducting power to illuminate the LEDs, the electrical connector being located within an interior cavity of said light fixture component and being connected within said interior cavity to a power conducting cable;

wherein the wall piece and light fixture component are configured to interlock such that when the light fixture component is attached to the wall piece, the circuit board is fixed in position to project light from the cove toward the ceiling of the room at a pre-selected fixed angle; and

wherein the reflector is positioned beneath the plurality of LEDs to redirect light emanating from the plurality of LEDs out through the light transmissive cover so as to increase the amount of light exiting the cove.

17. The LED cove light system of claim 16 wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a planar portion extending beneath the arcuate portion and over and parallel to a surface of the printed circuit board.

18. An LED cove light system comprising:

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

a wall piece mounted to the rear portion of the rear portion of the cove;

a light fixture component configured to removably attach to the wall piece and comprising (a) a circuit board mounting a plurality of LEDs, (b) a light transmissive cover positioned over the LEDs, and (c) a reflector positioned within the light transmissive cover;

wherein the LEDs are mounted in a row on a center line which is above and spaced apart from a center line of the circuit board;
