## Abstract

A connection device for a luminaire includes a housing that is intended for installation in a mounting space in a wall of a premises, this device including a connection socket for a luminaire and a connection zone for connection to an electrical network. The housing forms an interior volume inside which members for supplying the luminaire with electrical power, members for connection between the connection socket for the luminaire and the connection zone for connection to the electrical network and a system for control and communication with a unit external to the connection device are incorporated.

## Claims

### Claim 1

A connection device for a luminaire, comprising:
a housing that is intended for installation in a mounting space in a wall of a premises, said device comprising a connection socket for a luminaire and a connection zone for connection to an electrical network, wherein the housing forms an interior volume inside which members for supplying the luminaire with electrical power, members for connection between the connection socket for the luminaire and the connection zone for connection to the electrical network and a system for control and communication with a unit external to the connection device are incorporated,
wherein the system for control and communication comprises a radiofrequency communication antenna, wherein the device includes a front face that is rigidly connected to the housing and configured to protrude out of the mounting space, and wherein the antenna is installed in a zone of the device that is located in a volume delimited by the front face and protrudes out of the mounting space.

### Claim 2 (depends on 1)

The connection device according to claim 1, wherein the front face has a wall provided with a decrease in thickness forming a cavity oriented towards an inner side of the housing and in which the communication antenna is accommodated.

### Claim 3 (depends on 1)

The connection device according to claim 1, wherein the members for supplying the luminaire with electrical power are provided on a first circuit board that is mounted within the housing, in that the members for connection between the connection socket for the luminaire and the connection zone for connection to the electrical network are provided on a second circuit board that is mounted within the housing, and wherein the system for control and communication is provided on a third circuit board that is mounted within the housing.

### Claim 4 (depends on 3)

The connection device according to claim 3, wherein the first circuit board is oriented parallel to a centre axis of the housing, and wherein the second and third boards are oriented perpendicular to the centre axis, the second board being attached to a first axial edge of the first board, and the third board being attached to a second axial edge of the first board opposite the first axial edge along the centre axis.

### Claim 5 (depends on 4)

The connection device according to claim 4, wherein the circuit boards are attached with slot-fitting members and welds ensuring that the boards are electrically connected to one another.

### Claim 6 (depends on 4)

The connection device according to claim 4, wherein the second and third circuit boards have a semicircular outline centred on the centre axis and delimited by an inner wall of the housing, and a central aperture around a central shaft of the housing.
