Network addressable lighting device architecture

A network addressable lighting device having a logical network address based on a network addressing scheme and being configured for connection to a computer network through a cable that transmits electric power for powering one or more lighting elements of the lighting device and control data for addressing and controlling the lighting device, the lighting device comprising;

• a data printed circuit assembly defined on a first board and including a hybrid interface configured to connect to the cable and receive the electric power and the control data from a networked device, wherein the hybrid interface decouples the electric power from the control data, the data printed circuit further comprising a driver corresponding to the one or more lighting elements and at least one logic element for controlling a state of the driver based on the control data;
• a power printed circuit assembly defined on a second board that is separate from the first board and including a first power input element electrically coupled to the hybrid interface, via a first board to board stacker connector, to receive the electric power and the decoupled control data and separate the electric power from the decoupled data, wherein the power printed circuit assembly also includes a first power conversion element configured to convert the power to a first voltage that is appropriate for powering the driver and a second power conversion element to convert the power to a second voltage that is appropriate for the at least one logic element;
• wherein the data printed circuit assembly includes a second power input element for receiving power at the second voltage, via a second board to board stacker connector, from the second power conversion element, via the second board to board stacker connector, to provide power to the at least one logic element and power at the first voltage to provide power to the driver;
• and
• wherein the first power first power input element and the second power input element are physically remote from one another whereby EMI and EMC is reduced.
