Abstract

An apparatus including a galvanic connector configured to interconnect with a corresponding galvanic connector in an empty light fitting; a network interface configured to operate as a node in a data communications network; and a communications interface for enabling communication between an environment adjacent to the light fitting and the data communications network.

Claims

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, and

wherein 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.

2. The apparatus of claim 1, wherein the unique network identifier is defined by a replaceable smart card.

3. The apparatus of claim 1, wherein the galvanic connector is configured to interconnect with an empty light fitting by twisting.

4. The apparatus of claim 1, further comprising at least one processor;

and

at least one non-transitory memory including first computer program code and second computer program code,

the at least one non-transitory memory and the first computer program code configured to, with the at least one processor, cause the apparatus at least to control the communications interface to transmit the second computer code to a device, wherein the second computer code enables the device to communicate with the apparatus.

5. The apparatus of claim 1, wherein the exchangeable unit comprises an illumination source.

6. The apparatus of claim 1, further comprising a user actuated control enabling the user to control luminous flux level of the illumination source.

7. 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 communication functionality for the network interface, and

wherein the exchangeable unit is further configured to vary the additional communication functionality based upon interchanging the exchangeable unit;

an illumination source powered via the galvanic connector.

8. The apparatus of claim 7, further comprising a user actuated control enabling the user to control luminous flux level of the illumination source.

9. An interchangeable unit comprising:
