Abstract

A lighting fixture includes a fixture body, a lighting bay, a light source, and an auxiliary bay. The lighting bay is in a first portion of the fixture body. The light source is in the lighting bay, and is configured to provide light suitable for general illumination. The auxiliary bay is adjacent to the lighting bay in a second portion of the fixture body. The auxiliary bay includes a mounting surface suitable for mounting an auxiliary device in the auxiliary bay and an auxiliary bay frame surrounding the auxiliary bay, which supports and therefore allows for the installation of a removable auxiliary bay cover over the auxiliary bay. Providing the auxiliary bay in the fixture body allows auxiliary devices to be installed in a ceiling without any changes to the ceiling.

First claim

What is claimed is:

1. A lighting fixture for installation in a drop ceiling, the lighting fixture comprising:
a fixture body;
a lighting bay in a first portion of the fixture body;
a light source in the lighting bay, the light source configured to provide light suitable for general illumination;
an electronics housing on an upper surface of the fixture body and extending in a direction opposite of light emission from the light source, wherein the electronics housing is configured to store at least driver circuitry configured to provide a drive signal to the light source; and
an auxiliary bay adjacent to the lighting bay in a second portion of the fixture body, the auxiliary bay comprising:
a mounting surface configured to receive an auxiliary device in the auxiliary bay; and
an auxiliary bay frame surrounding the auxiliary bay and separating the auxiliary bay from the lighting bay, wherein the auxiliary bay is configured to support a removable auxiliary bay cover that is configured to be placed in the auxiliary bay frame to cover the auxiliary bay and the auxiliary device in the auxiliary bay, wherein the auxiliary bay is located below a plenum of the drop ceiling.

2. The lighting fixture of claim 1 wherein the light source comprises one or more light emitting diodes (LEDs).

3. The lighting fixture of claim 1 wherein the auxiliary bay further comprises an auxiliary device connector, which is coupled to a power source to provide power to the auxiliary device.

4. The lighting fixture of claim 3 wherein the auxiliary device connector is further configured to provide a data connection to the auxiliary device such that the auxiliary device is configured to communicate with one or more other devices.

5. The lighting fixture of claim 4 wherein the auxiliary device connector is an RJ45 connector.

6. The lighting fixture of claim 1 wherein the fixture body is configured to be mounted in the drop ceiling such that an upper surface of the fixture body is concealed above the drop ceiling and a lower surface of the fixture body is exposed below the drop ceiling.

7. The lighting fixture of claim 6 wherein the lighting bay and the auxiliary bay comprise the lower surface of the fixture body.

8. The lighting fixture of claim 1 further comprising:
driver circuitry configured to provide a drive signal to the light source such that the drive signal controls one or more characteristics of the light provided from the light source; and
a power source configured to provide power to the driver circuitry.

9. The lighting fixture of claim 8 wherein the power source is a Power over Ethernet (PoE) switch.

10. The lighting fixture of claim 8 wherein the power source is an alternating current (AC) to direct current (DC) converter.

11. The lighting fixture of claim 8 wherein the power source is an alternating current (AC) power source.

12. The lighting fixture of claim 8 wherein the power source is further configured to provide power to the auxiliary device.

13. The lighting fixture of claim 12 wherein the power source is a Power over Ethernet (PoE) switch.

14. The lighting fixture of claim 12 wherein the power source is an alternating current (AC) to direct current (DC) converter.

15. The lighting fixture of claim 12 wherein the auxiliary bay further comprises an auxiliary device connector configured to provide power from the power source to the auxiliary device.

16. The lighting fixture of claim 15 wherein the auxiliary device connector is further configured to provide a data connection to the auxiliary device such that the auxiliary device is configured to communicate with one or more other devices.

17. The lighting fixture of claim 16 wherein:
the driver circuitry is further configured to communicate with the one or more other devices; and
the data connection to the auxiliary device is provided via the driver circuitry.

18. The lighting fixture of claim 3 wherein the auxiliary device connector comprises a cable routed in the auxiliary bay frame and configured to be concealed from view when not in use.

19. The lighting fixture of claim 18 wherein the auxiliary bay frame includes a securing mechanism configured to secure the auxiliary connector to the auxiliary bay frame when not in use.
