Abstract
A system of networked lighting devices includes a central controller and a group of lighting devices. Each lighting device may include a fixture controller, one or more lighting modules, and a communication interface. The central controller receives data packets and send them to the lighting devices via a ring topology. The lighting devices may be connected to each other via the ring topology, or a set of routers may be connected in the ring topology, with each router controlling one or more connected lighting devices. The central controller and/or the fixture controllers may each translate data packets from one protocol to a different protocol. The different protocol may be a protocol that is compatible with the local system of networked devices, and/or a protocol that is compatible with the lighting device(s) that will use the data packets to actuate according to a command from the central controller.
