1. An apparatus comprising:
a galvanic connector configured to interconnect with a corresponding galvanic connector in an empty light fitting; a network interface, wherein the network interface comprises a radio transceiver, for wireless communication, powered via the galvanic connector, and wherein the network interface uses a unique network identifier, wherein the network interface is configured to operate as a terminal node in the data communications network and is configured to operate as an interconnecting node between different networks forming the data communications network; a communications interface for enabling communication between an environment adjacent to the light fitting and a data communications network, wherein the communications interface is configured to communicate data dependent upon the environment adjacent to the light fitting to the network interface and is configured to communicate data, for transmission into the environment adjacent to the light fitting, from the network interface; a base unit including the galvanic connector and a second galvanic connector to directly receive an exchangeable unit's galvanic connector,
wherein the exchangeable unit comprises at least part of the communications interface,wherein the exchangeable unit is configured to provide additional functionality to the base unit, andwherein the exchangeable unit is further configured to vary the additional functionality based upon interchanging the exchangeable unit; an illumination source powered via the galvanic connector. |
