Network addressable lighting device architecture
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.
