Abstract

A low-profile modular lighting device with flexible installation mounting options includes a lower housing, a circuit board supported by the lower housing and having electronic devices mounted thereto, and a plurality of upper housings each configured to releasably couple to the lower housing. The electronic devices of the circuit board extend within the space defined by an interior surface and upper edge of the lower housing and within the space defined by an interior surface and lower edge of each of the plurality of upper housings when coupled to the lower housing. Each of the plurality of upper housings provide a different mounting configuration for the modular lighting device. The modular lighting device may include one or more of a motion sensor, a light sensor, and a wireless transceiver for communication with a wireless lighting system.

First claim

What is claimed is:

1. A modular lighting device, comprising:
a lower housing;
a circuit board supported by the lower housing and having electronic devices mounted thereto; and
a plurality of upper housings each configured to releasably couple to the lower housing, a selected one of the plurality of upper housings coupled to the lower housing; and
wherein:
the electronic devices of the circuit board extend within a lower space defined by an interior surface and upper edge of the lower housing and within an upper space defined by an interior surface and lower edge of each of the plurality of upper housings when coupled to the lower housing;
the lower space and the upper space are contiguous; and
each of the plurality of upper housings provide a different mounting configuration for the modular lighting device.

2. The modular lighting device of claim 1 , wherein the circuit board is located within the upper space defined by the interior surface and lower edge of the upper housing when coupled to the lower housing, thereby minimizing a height of the lower housing.

3. The modular lighting device of claim 1 , wherein the electronic devices are mounted to an upper and a lower side of the circuit board.

4. The modular lighting device of claim 3 , wherein the circuit board and electronic devices mounted thereto are enclosed by the lower housing and each of the plurality of upper housings when coupled to the lower housing.

5. The modular lighting device of claim 1 , further comprising an annular cover releasably coupled with a bottom side of the lower housing, the annular cover spanning and concealing fasteners for at least one of mounting the modular lighting device and attaching the lower housing to one of the plurality of upper housings.

6. The modular lighting device of claim 1 , wherein the selected one of the plurality of upper housings is configured to enable mounting within a recess defined in a ceiling.

7. The modular lighting device of claim 6 , wherein:
the selected one of the plurality of upper housings is sized to be received within the recess; and
the lower housing is sized to cover an area of the ceiling larger than the recess, thereby concealing the recess upon mounting the modular lighting device to the ceiling recess.

8. The modular lighting device of claim 6 , wherein the selected one of the plurality of upper housings includes a pair of spring mounts for retaining the selected one of the plurality of upper housings within the recess.

9. The modular lighting device of claim 1 , wherein the selected one of the plurality of upper housings is configured to enable mounting upon a flat surface of a ceiling.

10. The modular lighting device of claim 1 , wherein the selected one of the plurality of upper housings includes a mounting arm terminating in a threaded conduit.

11. The modular lighting device of claim 1 , wherein the electronic devices include a motion sensor.

12. The modular lighting device of claim 11 , further comprising a lens coupled to a central portion of the lower housing, the lens concealing the motion sensor.

13. The modular lighting device of claim 11 , wherein the electronic devices include a light sensor.

14. The modular lighting device of claim 1 , wherein the electronic devices include a wireless transceiver for communication with a wireless lighting control system.

15. The modular lighting device of claim 1 , wherein at least another one of the plurality of upper housings is sized to couple with the lower housing and enclose the selected one of the plurality of upper housings coupled to the lower housing.

16. A modular lighting device, comprising:
a lower housing;
a circuit board supported by the lower housing and having electronic devices mounted thereto; and
a plurality of upper housings each configured to be coupled to the lower housing, a selected one of the plurality of upper housings coupled to the lower housing; and
wherein:
the electronic devices of the circuit board span vertically from below an upper edge of the lower housing to above a lower edge of each of the plurality of upper housings when coupled to the lower housing, thereby the circuit board and electronic devices extend within a space defined by both the lower housing and each of the plurality of upper housings when coupled to the lower housing; and
each of the plurality of upper housings provide a different mounting configuration for the modular lighting device.

17. The modular lighting device of claim 16 , wherein:
the selected one of the plurality of upper housings is configured to enable mounting within a recess defined in a ceiling and is sized to be received within the recess; and
the lower housing is sized to cover an area of the ceiling larger than the recess, thereby concealing the recess and the selected one of the plurality of upper housings upon mounting the modular lighting device to the ceiling recess.

18. The modular lighting device of claim 17 , wherein the selected one of the plurality of upper housings includes a pair of spring mounts for retaining the one of the plurality of upper housings within the recess.

19. The modular lighting device of claim 16 , wherein the selected one of the plurality of upper housings is configured to enable mounting the upper housing upon a flat surface of a ceiling.

20. The modular lighting device of claim 16 , wherein the selected one of the plurality of upper housings includes a threaded conduit end.

21. The modular lighting device of claim 16 , wherein the electronic devices of the circuit board include at least:
a motion sensor;
a light sensor;
a light emitter; and
a wireless transceiver for communication with a wireless lighting control system.

22. A modular lighting device, comprising:
a lower housing;
a circuit board supported by the lower housing and having electronic devices mounted thereto; and
a plurality of upper housings each configured to couple to the lower housing; and
wherein:
the electronic devices of the circuit board extend within a lower space defined by an interior surface and upper edge of the lower housing and within an upper space defined by an interior surface and lower edge of each of the plurality of upper housings when coupled to the lower housing;
the lower space and the upper space are contiguous;
each of the plurality of upper housings provide a different mounting configuration for the modular lighting device;
a first one of the plurality of upper housings is sized to be received within a recess enabling an upper edge of the lower housing to be mounted against ceiling;
a second one of the plurality of upper housings is configured to enable mounting the upper housing upon a flat surface of a ceiling; and

a third one of the plurality of upper housings includes a threaded conduit end.
