Wireless light fixture

1. An apparatus comprising:

a housing having an outer wall with an aperture;

a lighting element;

a first PCB section contained in the housing and having circuitry configured to control the lighting element; and

a second PCB section having an antenna and circuitry configured to convert RF signals into control signal input to the first PCB section, the second PCB section being operatively interconnected with the first PCB section;

wherein the second PCB section is installed in an orientation projecting outward through the aperture in the outer wall of the housing, with the antenna located at least partially outside the outer wall of the housing.

2. An apparatus comprising:

a housing having an outer wall with an aperture;

a lighting element;

a driver box contained in the housing;

a driver box cover closing the driver box and having an aperture;

a first PCB section contained in the driver box and having circuitry configured to control the lighting element; and

a second PCB section having an antenna and circuitry configured to convert RF signals into control signal input to the first PCB section, the second PCB section being operatively interconnected with the first PCB section inside the driver box;

wherein the second PCB section projects outward from the driver box through the aperture in the driver box cover, and projects further outward through the aperture in the outer wall of the housing, with the antenna located at least partially outside the outer wall of the housing.

3. An apparatus as defined in claim 2 wherein the housing includes a nonmetallic antenna cover received over the second PCB section and covering the second PCB section outside the outer wall of the housing.

4. An apparatus as defined in claim 3 wherein the antenna cover has a part projecting outward through the aperture in the driver box cover.

5. An apparatus as defined in claim 4 wherein the part of the antenna cover that projects outward through the aperture in the driver box cover is interlocked with the driver box cover.

6. An apparatus as defined in claim 4 wherein the antenna cover has a separate part received over the part that projects outward through the aperture in the driver box cover.

7. An apparatus as defined in claim 6 wherein the separate part of the antenna cover is fastened to the outer wall of the housing over the aperture in the outer wall.

8. An apparatus as defined in 2 wherein the antenna is located entirely outside the outer wall of the housing.

9. An apparatus as defined in claim 2 wherein the first PCB section is part of a first PCB and the second PCB section is part of a second PCB coupled with the first PCB.

10. An apparatus as defined in 1 wherein the antenna is located entirely outside the outer wall of the housing.

11. An apparatus as defined in claim 1 wherein the outer wall of the housing is foamed of material that includes metallic material.

12. An apparatus as defined in claim 11 wherein the housing includes a nonmetallic antenna cover received over the second PCB section and covering the second PCB section outside the outer wall of the housing.

13. An apparatus as defined in claim 12 wherein the antenna cover has a part projecting outward through the aperture in the outer wall of the housing.

14. An apparatus as defined in claim 13 wherein the antenna cover has a separate part received over the part that projects outward through the aperture in the outer wall of the housing.

15. An apparatus as defined in claim 14 wherein the separate part of the antenna cover is fastened to the outer wall of the housing over the aperture in the outer wall.
