Abstract: An network addressable lighting device that receives the input power from a power source (PSE), such as a network Power Over Ethernet (PoE) source, at a physical interface and data assembly PIDA and passes the signal directly to a second power assembly (PA) while the AC coupled high-speed data lines stay exclusively on the PIDA that contains the input and output physical interfaces, such as RJ interfaces. All power rails required to run the PIDA are converted on the PA and can then be sent back to the PIDA via low-cost conventional board stacker connectors. Movement of the high-current is done on the power assembly and not the data assembly where the sensitive communications primarily occur. The implementations thus provide an ideal separation of power and data structures to reduce EMI/EMC issues in a low cost and compact device.

Abstract: A control system for controlling a networked system of multiple individually addressable devices, such as lighting devices, each having a logical address based on a network addressing scheme, each lighting device being connected to a computer network through a cable that transmits electric power for powering one or more lighting elements of the lighting device and hierarchical control data for addressing and controlling the lighting device. Each lighting device includes a controller for receiving the hierarchical control data and controlling a state of the one or more lighting elements in accordance with the control data.
