Abstract

A light fixture is described herein. The light fixture can include a housing having at least one wall that forms a cavity. The light fixture can also include a controller configured to control and communicate with at least one sensor located outside the housing. The light fixture can further include at least one light fixture component coupled to the controller and disposed within the cavity of the housing, where the controller further controls the at least one light fixture component.

Claims

1. A light fixture for communicating with a network manager and at least one sensor, the light fixture comprising:

light fixture components; and

a controller for operating the light fixture components and communicating with the network manager, the controller being configured to

receive an instruction from the network manager,

establish control of at least one sensor based on the received instruction from the network manager, and

receive sensor data from the at least one sensor.

2. The light fixture of claim 1, wherein the light fixture components comprise one or more of a light source or a light engine.

3. The light fixture of claim 1, wherein the controller is further configured to receive a request from a second sensor, associate with the second sensor based on the received request, and receive second sensor data from the second sensor.

4. The light fixture of claim 1, wherein the controller is further configured to send a request to end sleep mode to the at least one sensor and receive more sensor data from the at least one sensor.

5. The light fixture of claim 1, wherein the controller is further configured to send a request to enter sleep mode to the at least one sensor.

6. The light fixture of claim 1, wherein the controller is further configured to communicate to the network manager by sending and receiving data through a second controller of a second light fixture.

7. The light fixture of claim 1, wherein the controller is further configured to control operation of the light fixture components responsive to the received sensor data from the at least one sensor.

8. A method for providing a network manager access to sensor data, the method performed by a controller and comprising the steps of:

receiving an instruction from the network manager;

establishing control of at least one sensor based on the received instruction from the network manager;

receiving sensor data from the at least one sensor; and

sending one or more data packets comprising the sensor data to the network manager.

9. The method of claim 8, further comprising receiving a request from a second sensor, associating with the second sensor based on the received request, and receiving second sensor data from the second sensor.

10. The method of claim 8, further comprising sending a request to end sleep mode to the at least one sensor and receiving more sensor data from the at least one sensor.

11. The method of claim 8, further comprising sending a request to enter sleep mode to the at least one sensor.

12. The method of claim 8, further comprising communicating to the network manager including sending and receiving data through a second controller.

13. The method of claim 8, further comprising controlling operation of light fixture components responsive to the received sensor data from the at least one sensor.

14. A light fixture for communication with a network manager and multiple sensors external to the light fixture, the light fixture comprising:

light fixture components; and

a controller for operating the light fixture components and communicating with the network manager, the controller being configured to

establish control of the multiple sensors in response to one or more instructions from the network manager;

receive sensor data from the multiple sensors,

generate one or more data packet based on the received sensor data from the multiple sensors, and

send the one or more data packet to the network manager.

15. The light fixture of claim 14, wherein the light fixture components comprise one or more of a light source or a light engine.

16. The light fixture of claim 14, wherein the controller is further configured to send a request to end sleep mode to one of the multiple sensors and receive more sensor data from the one of the multiple sensors.

17. The light fixture of claim 14, wherein the controller is further configured to send a request to enter sleep mode to one of the multiple sensors.

18. The light fixture of claim 14, wherein the controller is further configured to communicate to the network manager by sending and receiving data through a second controller of a second light fixture.

19. The light fixture of claim 14, wherein the controller is further configured to control operation of the light fixture components responsive to the received sensor data from one of the multiple sensors.

20. The light fixture of claim 14, wherein the controller is further configured to control operation of the light fixture components responsive to the received sensor data from one of the multiple sensors but not from another of the multiple sensors.
