Abstract

A cover of a lighting device includes a front surface and a back surface, where the back surface is on an opposite side of the front surface. The cover further includes an antenna formed in the back surface, where the antenna is exposed on the back surface of the cover.

Claims

1. A cover of a lighting device, the cover comprising:

a front surface and a back surface, wherein the back surface is on an opposite side of the front surface; and

an antenna formed in the back surface, wherein the antenna is exposed on the back surface of the cover.

2. The cover of claim 1, further comprising a contact pad coupled to the antenna, wherein the contact pad is positioned to make an electrical contact with a pad or a pin extending from a printed circuit board.

3. The cover of claim 1, further comprising an electrical wire coupled to and extending from the antenna.

4. The cover of claim 1, wherein the cover is made from plastic.

5. The cover of claim 4, wherein the antenna is made from copper.

6. The cover of claim 1, wherein an opening is formed in the cover.

7. The cover of claim 6, wherein the lighting device is a dimmer or a light switch.

8. The cover of claim 6, wherein the lighting device is a power outlet.

9. The cover of claim 1, wherein the cover is an end cap or a trim of a lighting fixture.

10. A cover of a lighting device, the cover comprising:

a front surface, a back surface, and an opening through the cover, wherein the back surface is on an opposite side of the front surface;

a first antenna formed in the back surface, wherein the first antenna is exposed on the back surface of the cover; and

a second antenna formed in the back surface, wherein the second antenna is exposed on the back surface of the cover.

11. The cover of claim 10, further comprising a first contact pad coupled to the first antenna, a second contact pad coupled to the second antenna, wherein each contact pad is positioned to make electrical contacts with a respective pad or pin extending from a printed circuit board.

12. The cover of claim 10, wherein the cover is an end cap or a trim of a lighting fixture and wherein the lighting device includes the lighting fixture.

13. The cover of claim 10, wherein the cover is made from plastic, and wherein the antenna is made from copper.

14. The cover of claim 10, wherein an opening is formed in the cover.

15. The cover of claim 14, wherein the cover is a portion of a dimmer, a light switch, or a power outlet.

16. A lighting device, comprising:

a wireless transceiver;

a cover plate having a front surface and a back surface, wherein the back surface is on an opposite side of the front surface; and

an antenna formed in the back surface, wherein the antenna is exposed on the back surface of the cover plate and wherein the antenna is electrically coupled to the wireless transceiver.

17. The lighting device of claim 16, further comprising a second antenna formed in the back surface, wherein the second antenna is exposed on the back surface of the cover plate.

18. The lighting device of claim 17, further comprising an electrical component that analyzes an electrical signal from each of the first antenna and the second antenna to determine a direction or location of a transmitting device that transmits a wireless signal received by the first antenna and the second antenna.

19. The lighting device of claim 16, wherein the lighting device is a lighting switch, a dimmer, a power outlet, or a wallstation.

20. The lighting device of claim 16, wherein the lighting device is a lighting fixture and wherein the cover plate is an end cap or a trim.
