Abstract: The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.

Abstract: A lighting fixture includes a light source, a housing coupled to the light source, communications circuitry, sensor circuitry, and control circuitry. The housing includes an opening through which light from the light source is provided. The control circuitry includes a memory storing instructions, which, when executed by the control circuitry cause the lighting fixture to transmit sensor data obtained from the sensor circuitry via the communications circuitry for persistent storage of the sensor data. By transmitting sensor data from the lighting fixture for persistent storage thereof, the sensor data may be used to characterize a space in which the lighting fixture is located.

The housing includes an opening through which light from the light source is provided. The control circuitry includes a memory storing instructions, which, when executed by the control circuitry cause the lighting fixture to adjust one or more light output parameters of the light source, and store fixture location information describing a location of the lighting fixture in response to receipt of the fixture location information from the communications circuitry. By storing fixture location information describing the location of the lighting fixture, the location of the lighting fixture may be used to send messages to lighting fixtures in the same location and/or retrieve data from lighting fixtures in the same location, which may be beneficial in many circumstances.

Abstract: The present disclosure relates to lighting fixtures for use in a lighting network where the lighting fixtures and other elements are able to communicate with each other via wired or wireless communication techniques. When the lighting network is being formed or modified, a lighting fixture is selected to act as a coordinator for forming the lighting network. For example, a user may employ a commissioning tool to select a particular lighting fixture as the coordinator. The coordinator will send out one or more ‘join my network’ messages toward the other elements of the lighting network. The elements that receive the ‘join my network’ message may respond in order to make the coordinator aware of their presence and join them to a lighting network.

Abstract: Systems and methods related to lighting fixtures for solid-state light sources are disclosed. In one embodiment, a lighting fixture includes a driver module and a communications module. The driver module is configured to execute driver program code, which causes the driver module to generate a drive output that drives one or more solid-state light sources. To provide updates, the communications module is configured to receive updated driver program code from a remote device and send the updated driver program code to the driver module. The driver module is configured to erase the driver program code and write the updated driver program code received from the communications module to memory. In this manner, updates can be provided to the lighting fixture without having to remove the lighting fixture from a support structure.

Abstract: The present disclosure relates to lighting fixtures for use in a lighting network where the lighting fixtures and other elements are able to communicate with each other via wired or wireless communication techniques. When the lighting network is being formed or modified, the lighting fixtures may be able to communicate with each other and automatically determine a single lighting fixture to act as a coordinator during a commissioning process. The lighting fixtures can exchange their communication addresses, such as MAC addresses, wherein the lighting fixture with the lowest (or highest) normal communication address becomes the coordinator. The coordinator may also be configured to assign short addresses to use for communications once the lighting network is formed instead of the longer MAC, or like, addresses. The short addresses can reduce routing overhead, and thus make the routing of messages including control information, sensor data, and the like, more efficient.
