Abstract

A lighting fixture includes an LED light source that outputs light for general illumination in response to a drive signal, and a driver module configured to provide the drive signal in response to an intelligent lighting module (ILM) instruction. An ILM that is separate from the driver module is provided and has a first plurality of sensors, a first communication interface, a second communication interface, and first control circuitry. The control circuitry of the ILM is configured to communicate with at least one remote entity via the first communication interface as well as generate the ILM instruction for the driver module based on sensor data gathered from the first plurality of sensors, remote entities, or a combination thereof. The ILM instruction is provided to the driver module via the second communication interface and used by the driver module to control the drive signal for the LED array.

First claim

What is claimed is:

1. A lighting fixture comprising:
a light emitting diode (LED) light source that outputs light for general illumination in response to a drive signal;
a driver module configured to provide the drive signal in response to an intelligent lighting module (ILM) instruction; and
a first ILM that is separate from the driver module and comprises:
a first plurality of sensors that comprises at least two different types of sensors;
a first communication interface
a second communication interface; and
first control circuitry communicatively coupled with the first plurality of sensors, the first communication interface, and the second communication interface, and configured to:
communicate with at least one remote entity via the first communication interface;
generate the ILM instruction based on sensor data gathered from the first plurality of sensors; and
provide the ILM instruction to the driver module via the second communication interface, wherein the light for general illumination is controlled by the first ILM, and communications between the lighting fixture and the at least one remote entity are facilitated by the first ILM.

2. The lighting fixture of claim 1 wherein generation of the ILM instruction is further based on information received from the at least one remote entity via the first communication interface.

3. The lighting fixture of claim 2 wherein the information received from the at least one remote entity includes sensor data gathered by at least one sensor associated with the at least one remote entity.

4. The lighting fixture of claim 2 wherein the information received from the at least one remote entity includes an instruction from the at least one remote entity.

5. The lighting fixture of claim 2 wherein the at least one remote entity is another lighting fixture.

6. The lighting fixture of claim 2 wherein the at least one remote entity is a wall controller.

7. The lighting fixture of claim 1 wherein the first communication interface is a wireless communication interface configured to facilitate wireless communications.

8. The lighting fixture of claim 1 wherein the first communication interface is a wired communication interface configured to facilitate wired communications.

9. The lighting fixture of claim 1 wherein the driver module is configured to provide a DC power signal, and the ILM is powered by the DC power signal.

10. The lighting fixture of claim 9 wherein the driver module is configured to receive an AC power signal and generate the DC power signal from the AC power signal.

11. The lighting fixture of claim 1 further comprising a cradle configured to releasably engage the first ILM.

12. The lighting fixture of claim 11 wherein the cradle provides a snap-fit engagement with the first ILM.

13. The lighting fixture of claim 1 wherein the first ILM is replaceable with a second ILM, which comprises a second plurality of sensors, a third communication interface, a fourth communication interface, and control circuitry, which is configured to:
communicate with the at least one remote entity via the third communication interface;
generate the ILM instruction based on sensor data gathered from the second plurality of sensors; and
provide the ILM instruction to the driver module via the fourth communication interface, wherein the light for general illumination is controlled by the second ILM, and the communications between the lighting fixture and the at least one remote entity are facilitated by the second ILM once the first ILM is replaced with the second ILM.

14. The lighting fixture of claim 13 wherein the first plurality of sensors and the second plurality of sensors comprise a same number and a same type of sensors.

15. The lighting fixture of claim 13 wherein the first plurality of sensors and the second plurality of sensors comprise at least one different type of sensor.

16. The lighting fixture of claim 13 wherein the first plurality of sensors and the second plurality of sensors comprise a different number of sensors.

17. The lighting fixture of claim 1 wherein the LED light source is configured such that the light for general illumination illuminates an area and the first ILM is exposed to the area when the lighting fixture is installed.

18. The lighting fixture of claim 1 wherein the first ILM further comprises a housing that releasably engages a structural member of the lighting fixture.

19. An intelligent lighting module (ILM) for a lighting fixture that has an LED light source that outputs light for general illumination in response to a drive signal, and a driver module configured to provide the drive signal in response to an ILM instruction, the ILM comprising:
a plurality of sensors that comprises at least two different types of sensors;
a first communication interface
a second communication interface; and
control circuitry communicatively coupled with the plurality of sensors, the first communication interface, and the second communication interface, and configured to:
communicate with at least one remote entity via the first communication interface;
generate the ILM instruction based on sensor data gathered from the plurality of sensors; and
provide the ILM instruction to the driver module via the second communication interface, wherein the light for general illumination is controlled by the ILM, and communications between the lighting fixture and the at least one remote entity is facilitated by the ILM.

20. The ILM of claim 19 wherein generation of the ILM instruction is further based on information received from the at least one remote entity via the first communication interface.

21. The ILM of claim 20 wherein the information received from the at least one remote entity includes sensor data gathered by at least one sensor associated with the at least one remote entity.

22. The ILM of claim 20 wherein the information received from the at least one remote entity includes an instruction from the at least one remote entity.

23. The ILM of claim 20 wherein the at least one remote entity is another lighting fixture.

24. The ILM of claim 20 wherein the at least one remote entity is a wall controller.
