Abstract

The invention provides a light emitting tufted carpet ( 1 ). The carpet ( 1 ) comprises a primary backing layer ( 100 ), an optional secondary backing layer ( 200 ), an optional adhesive layer ( 300 ), a plurality of carpet integrated LEDs ( 40 ) arranged to generate carpet light ( 41 ), and a first electric conductor ( 10 ) and a second electric conductor ( 20 ). The first electric conductor ( 10 ) and the second electric conductor ( 20 ) are arranged to provide power from a power source ( 50 ) to the LEDs ( 40 ). The primary backing layer ( 100 ) comprises a first felt layer ( 30 ′), or the optional secondary backing layer ( 200 ) comprises second felt layer ( 30 ″), or both the primary backing layer ( 100 ) and the optional secondary backing layer ( 200 ) comprise felt layers ( 30′,30 ″). One or more of the first electric conductor ( 10 ) and the second electric conductor ( 20 ) are at least partially integrated in one or more of the first felt layer ( 30 ′) and the second felt layer ( 30 ″).

Claims (39)

1. A light emitting tufted carpet comprising:

primary and secondary backing layers each including a top surface and a felt layer;

a plurality of LEDs arranged to generate light; and

a first electric conductor and a second electric conductor for conducting power from a power source to the LEDs,

wherein one or more of the felt layer of the primary backing layer and the felt layer of the secondary backing layer is one or more of the first and second electric conductors.

2. The light emitting carpet according to claim 1 , further comprising an adhesive layer arranged between at least a part of the primary backing layer and the secondary backing layer.

3. The light emitting carpet according to claim 2 , wherein one or more of the plurality of LEDs are arranged in a recess of a layer selected from the group consisting of the primary backing layer, the secondary backing layer, and the adhesive layer.

4. The light emitting carpet according to claim 1 , wherein one or more of the felt layers comprises a stack.

5. The light emitting carpet according to claim 1 , wherein at least part of one or more of the first electric conductor and the second electric conductor are arranged in a plane parallel to at least one top surface.

6. The light emitting carpet according to claim 1 , wherein one or more of the first electric conductor and the second electric conductor comprise an electrical wire.

7. The light emitting carpet according to claim 1 , wherein one or more of the felt layers comprise conductive felt strips separated by non-conductive material.

8. The light emitting carpet according to claim 7 , wherein the felt layer of the primary backing layer is the first electric conductor and the felt layer of the secondary backing layer is the second electric conductor.

9. The light emitting carpet according to claim 7 , wherein one or more of the felt layers form a stack comprising a first stack conductor and a second stack layer conductor with an isolator arranged between the first and the second felt stack conductors.

10. The light emitting carpet according to claim 9 , wherein the felt layer of the secondary backing layer comprises the stack.

11. The light emitting carpet according to claim 1 , wherein one or more of the first electric conductor and the second electric conductor comprise an electrical conductive felt strip.

12. The light emitting carpet according to claim 2 , wherein the adhesive layer is permeable to light and wherein the LEDs are arranged in one or more of the adhesive layer and the secondary backing layer.

13. The light emitting carpet according to claim 1 , further comprising a controller to individually control the optical properties of two or more subsets of LEDs of the plurality of LEDs.

14. The light emitting carpet according to claim 1 , wherein one or more of the felt layers are heat conductive.

15. A light emitting tufted carpet comprising

a primary backing having a felt layer,

a plurality of LEDs arranged to generate light, and

at least one electric conductor integrated in the felt layer to provide power from a power source to the LEDs, wherein the felt layer of the primary backing is the at least one electric conductor.

16. The light emitting tufted carpet according to claim 15 , further comprising a secondary backing having a felt layer, wherein the at least one electric conductor is at least two electric conductors at least partially integrated in the felt layer of the primary or the secondary backing.

17. A light emitting tufted carpet comprising:

primary and secondary backing layers each including a top surface and a felt layer;

a plurality of LEDs arranged to generate light; and

a first electric conductor and a second electric conductor for conducting power from a power source to the LEDs,

wherein one or more of the first and second electric conductors are at least partially integrated in one or more of the felt layers and the felt layer of the primary backing layer is the first electric conductor and the felt layer of the secondary backing layer is the second electric conductor.

18. A light emitting tufted carpet comprising:

primary and secondary backing layers each including a top surface and a felt layer;

a plurality of LEDs arranged to generate light; and

a first electric conductor and a second electric conductor for conducting power from a power source to the LEDs,

wherein one or more of the first and second electric conductors are at least partially integrated in one or more of the felt layers and one or more of the felt layers form a stack comprising a first stack conductor and a second, stack layer conductor with an isolator arranged between the first and the second felt stack conductors.

19. A light emitting tufted carpet comprising:

primary and secondary backing layers each including a top surface and a felt layer;

a plurality of LEDs arranged to generate light;

a first electric conductor and a second electric conductor for conducting power from a power source to the LEDs; and

an adhesive layer arranged between at least a part of the primary backing layer and the secondary backing layer,

wherein the adhesive layer is permeable to light and wherein the LEDs are arranged in one or more of the adhesive layer and the secondary backing layer.
