Abstract

A lighting fixture includes a solid-state light source, communications circuitry, a memory, and processing circuitry. The memory stores common security credentials, wherein the common security credentials are pre-installed during a factory calibration process. The processing circuitry is coupled to the solid-state light source, the communications circuitry, and the memory. The processing circuitry is configured to cause the solid-state light source to provide a desired light output. Further, the processing circuitry is configured to join a common network using the common security credentials, wherein only devices with the common security credentials are permitted to join the network.

First claim

What is claimed is:

1 . A lighting fixture comprising:
a solid-state light source; communications circuitry; a memory storing common security credentials, wherein the common security credentials are pre-installed during a factory calibration process; and processing circuitry coupled to the solid-state light source, the communications circuitry, and the memory and configured to:
cause the solid-state light source to provide a desired light output; and
create a common network using the common security credentials, wherein only devices with the common security credentials are permitted to join the common network.

2 . The lighting fixture of claim 1 wherein creating the common network comprises authenticating devices wishing to join the common network based on the common security credentials.

3 . The lighting fixture of claim 2 wherein creating the common network further comprises assigning an address to the devices wishing to join the common network that are authenticated based on the common security credentials.

4 . The lighting fixture of claim 2 wherein the processing circuitry is further configured to:
receive a command to create the common network from a device; and
create the common network in response to the command.

5 . The lighting fixture of claim 4 wherein creating the common network comprises authenticating the devices wishing to join the common network based on the common security credentials.

6 . The lighting fixture of claim 5 wherein creating the common network further comprises assigning an address to the devices wishing to join the common network that are authenticated based on the common security credentials.

7 . The lighting fixture of claim 4 wherein the command is provided via the common network.

8 . The lighting fixture of claim 4 wherein the command is not provided via the common network.

9 . The lighting fixture of claim 8 further comprising a light sensor, wherein the command is provided via the light sensor.

10 . The lighting fixture of claim 1 wherein the processing circuitry is further configured to:
communicate with a device in the common network via the communications circuitry;
receive updated security credentials from the device via the communications circuitry and store the updated security credentials in the memory; and
communicate with other devices in the common network using the updated security credentials.

11 . The lighting fixture of claim 10 wherein the processing circuitry is further configured to:
attempt to join another common network using the common security credentials; and
create the common network using the common security credentials if the attempt to join the another common network is unsuccessful.

12 . The lighting fixture of claim 11 wherein the processing circuitry is further configured to:
communicate with a device in the another common network via the communications circuitry if the attempt to join the another common network is successful; and
receive updated security credentials from the device via the communications circuitry and store the updated security credentials in the memory.

13 . The lighting fixture of claim 12 wherein the processing circuitry is further configured to use the updated security credentials to communicate over the common network.

14 . The lighting fixture of claim 13 wherein the processing circuitry is further configured to forward the updated security credentials to an additional device in the common network.

15 . The lighting fixture of claim 12 wherein the device authenticates the lighting fixture to allow the lighting fixture to join the common network.

16 . The lighting fixture of claim 12 wherein the updated security credentials are generated by the device.

17 . The lighting fixture of claim 12 wherein the lighting fixture and the device form a Thread network.

18 . The lighting fixture of claim 11 wherein the processing circuitry is further configured to attempt to join the another common network using the common security credentials by attempting to join the another common network on each one of a number of different channels.

19 . The lighting fixture of claim 11 wherein the processing circuitry is further configured to attempt to join the another common network using the common security credentials by sending a request join message and waiting for a response.

20 . The lighting fixture of claim 19 wherein the processing circuitry is further configured to determine the attempt to join the another common network is unsuccessful by waiting a predetermined amount of time after sending the request join message before creating the common network.
