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.
Claims21
A lighting fixture comprising:
- a solid-state light source;
- communications circuitry;
- a memory storing pre-installed common security credentials, wherein the pre-installed 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;
- create a common lighting network using the pre-installed common security credentials, wherein only devices identified by light modulation sent from the first light fixture and with pre-installed common security credentials identical to the pre-installed common security credentials stored in the memory of the lighting fixture are permitted to join the common lighting network;
- and
- communicate with devices of the common lighting network by modulating light from the solid-state light source.
A distributed lighting network, comprising:
- a plurality of common lighting networks, the plurality of common lighting networks comprising a first common lighting network and a second common lighting network;
- a first lighting fixture comprising:
- a solid-state light source;
- communications circuitry;
- a memory storing common security credentials;
- and
- processing circuitry coupled to the solid-state light source, the communications circuitry, and the memory and configured to:
- cause a network join message to be transmitted to the first common lighting network and to the second common lighting network;
- and
- create a third common lighting network based on a lack of responses from the first common lighting network and the second common lighting network, wherein only devices identified by light modulation sent from the first lighting fixture and with common security credentials identical to the common security credentials stored in the memory of the lighting fixture are permitted to join the third common lighting network.
A method of operating a lighting fixture, the method comprising:
- transmitting a network join message to a distributed lighting network, the distributed lighting network comprising a first common lighting network and a second common lighting network;
- waiting a predetermined amount of time to receive a response from the first common lighting network and the second common lighting network;
- and
- after the predetermined amount of time has passed, and based on not receiving responses from the first common lighting network and the second common lighting network, creating a third common lighting network, the creating comprising:
- designating, by the lighting fixture, the lighting fixture as a network leader;
- receiving a network join message from a device that is identified by light modulation sent from the lighting fixture;
- and
- adding the device to the third common lighting network based on the lighting fixture and the device sharing a same common security credentials.
