Abstract

An LED cove light system having a wall piece mounted to a back surface of a cove and a light fixture component removably attachable at an angle to the wall piece. The light fixture component carries a plurality of LEDs beneath an arcuate portion of a lens and a reflector is positioned below the LEDs. A baffle component is mounted within the lens and configured to control lateral light distribution.

Claims

1. An LED cove light fixture comprising:

a mounting track having a rear surface and adapted to be mounted to a rear portion of a cove;

a light fixture component attachable to the mounting track and comprising a circuit board mounting a plurality of LEDs on a top surface thereof and a light transmissive cover having an arcuate portion positioned over the plurality of LEDs;

wherein the light fixture component is further configured to interlock with the mounting track so as to project light out of a cove at a fixed angle toward a ceiling of a room when attached to the mounting track;

wherein said light fixture component further comprises a reflector positioned within the light transmissive cover and beneath the LEDs so as to redirect light emanating from the plurality of LEDs out through the lens so as to increase the amount of light exiting the cove;

and further comprising a baffle having a flat bottom surface attached to the top surface of the printed circuit board, the baffle being disposed beneath the arcuate portion of the light transmissive cover, the baffle having a plurality of baffle elements, each of the plurality of LEDs being positioned in a recess in said flat bottom surface located between a respective pair of baffle elements, each baffle element having first and second surfaces shaped to mate respectively with an inner surface of the arcuate portion of the light transmissive cover and a reflective surface of the reflector.

2. The LED cove light fixture of claim 1 wherein the light fixture component is configured so as to enable 85% or more of the light generated by the LEDs to exit the cove when the light fixture component is interlocked with the mounting track.

3. The LED cove light fixture of claim 1 wherein each baffle element mates flushly with the inner surface of said arcuate portion and flushly with said reflective surface such that no light can be transmitted within the light transmissive cover from one side of a baffle element to the other side of that baffle element.

4. The LED cove light fixture of claim 1 wherein, as one proceeds down a length of the baffle, first and second of the baffle elements are joined together by a first web portion of said flat bottom surface, second and third baffle elements are joined together by a second web portion of said flat bottom surface including a first recess shaped to accommodate a first respective LED, third and fourth baffle elements are joined together by a third web portion of said flat bottom surface of equal length to the first web portion, and fourth and fifth baffle elements are joined together by a fourth web portion of said flat bottom surface including a second recess shaped to accommodate a second respective LED.

5. The LED cove light fixture of claim 1 wherein the bottom surface of the baffle is attached to the top surface of the circuit board by double sided adhesive tape.

6. 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 comprising a circuit board having a top surface mounting a plurality of LEDs;

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; and

wherein the light transmissive cover comprises an arcuate portion positioned over the LEDs and a flat planar portion extending beneath the arcuate portion and over the printed circuit board;

and further comprising a baffle having a flat bottom surface attached to the top surface of the printed circuit board, the baffle being disposed beneath the arcuate portion of the light transmissive cover, the baffle having a plurality of baffle elements, each of the plurality of LEDs being positioned in a recess in said flat bottom surface, each recess being located between a respective pair of baffle elements, each baffle element having first and second surfaces shaped to mate respectively with an inner surface of the arcuate portion of the light transmissive cover and a reflective surface of the reflector.

7. The LED cove light system of claim 6 wherein the light fixture component is configured 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.

8. The LED cove light system of claim 6 wherein each baffle element mates flushly with the inner surface of said arcuate portion and flushly with said reflective surface such that no light can be transmitted within the light transmissive lens from one side of a baffle element to the other side of that baffle element.

9. The LED cove light system of claim 6 wherein, as one proceeds down a length of the baffle, first and second of the baffle elements are joined together by a first web portion of said flat bottom surface, second and third baffle elements are joined together by a second web portion of said flat bottom surface including a first recess shaped to accommodate a first respective LED, third and fourth baffle elements are joined together by a third web portion of said flat bottom surface of equal length to the first web portion, and fourth and fifth baffle elements are joined together by a fourth web portion of said flat bottom surface including a second recess shaped to accommodate a second respective LED.

11. The LED cove light system of claim 6 wherein the bottom surface of the baffle is attached to the top surface of the circuit board by double sided adhesive tape.

10. An LED cove light fixture comprising:

a mounting track having a rear surface and adapted to be mounted to a rear portion of a cove;

a light fixture component attachable to the mounting track and comprising a circuit board having a top surface mounting a plurality of LEDs and a light transmissive cover having an arcuate portion positioned over the plurality of LEDs;

wherein the light fixture component is further configured to interlock with the mounting track so as to project light out of a cove at a fixed angle toward a ceiling of a room when attached to the mounting track;

wherein said light fixture component further comprises a reflector positioned within the light transmissive cover and beneath the LEDs so as to redirect light emanating from the plurality of LEDs out through the lens so as to increase the amount of light exiting the cove;

and further comprising a baffle having a bottom surface attached to the top surface of the printed circuit board, the baffle being disposed beneath the arcuate portion of the light transmissive cover, the baffle having a plurality of baffle elements, a plurality of pairs of said baffle elements being joined by a web portion of said bottom surface, each web portion having a recess therein, wherein one of the plurality of LEDs is located in each recess, each baffle element having first and second surfaces shaped to mate respectively with an inner surface of the arcuate portion of the light transmissive cover and a reflective surface of the reflector.

12. The LED cove light fixture of claim 10 wherein the light fixture component is configured 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.

13. The LED cove light fixture of claim 12 wherein each baffle element mates flushly with the inner surface of said arcuate portion and flushly with said reflective surface such that no light can be transmitted within the light transmissive cover from one side of a baffle element to the other side of that baffle element.
