By proposing a communication assembly which is integrated into the housing of a luminaire as defined above, a compact integrated connected luminaire is proposed in which the communication functionalities are grouped in a functional manner. In comparison with the solutions of the prior art in which the communication elements are provided in a module which is connected by means of a socket to the housing of a luminaire, the embodiments of the invention offer the advantage of so that the box can be more compact while still allowing good communication of data vis-à-vis the power supply and light control.

According to one embodiment, the light supply and control assembly comprises a programmable control means designed to control and configure the luminaire taking into account the data of the signals received. The data can include various types of data used to configure and control the luminaire, such as detection data from neighboring luminaires, configuration profiles received from a centralized controller, diagnostic data, real-time dimming, etc. The data may relate to data for controlling a dimming means, data for controlling the measurements made by sensors and detectors, for example. ex. at least one light sensor, etc. Preferably, the light supply and control assembly comprises a dimming means designed to vary the intensity of the light source, and the programmable control means is designed to control the dimming means taking into account data received or saved. The dimming means can be controlled for example as a function of the signals received from the antenna, as a function of measurement data, or as a function of recorded gradation profile data. More preferably, the light supply and control assembly has dimming means designed to process a dimming signal according to standard protocols, e.g. 0 - 10 V, 1 - 10 V or DALI.

According to one embodiment, the luminaire further comprises a location unit such as a GPS reception means, and the communication circuit is designed to process the signals received by the location unit. Preferably, the location unit is also provided on the support substrate. In this way, the location of the luminaire can be communicated to other devices, such as a centralized control unit or the adjacent luminaires, possibly in combination with other data such as detection data. It should also be noted that the luminaire may comprise, in addition to a light sensor, various other sensors and detectors such as an image sensor (eg a camera), an audio sensor, a

BE2018 / 5175 air quality detector, motion detector, etc. The communication circuit and / or the light supply and control assembly can then be further designed to exploit and / or transmit the data captured by one or more of these additional sensors and detectors.

The antenna can be highly directional or not. Omnidirectional antennas can also be used. The antenna can be any type of antenna, such as an RF antenna, a Bluetooth antenna, a near-field communication antenna, etc. Likewise, a plurality of antennas may be used.

According to one embodiment, the housing comprises a first housing part having an opening and a second housing part comprising the electrically non-conductive part. The second housing part is designed to close the opening. In such an embodiment, the antenna may include a radiating part located at least partially inside the second housing part. In an exemplary embodiment, the antenna comprises a radiating part which extends in an antenna plane situated externally relative to the first housing part, at a distance less than 15 mm, preferably less than 13 mm, more preferably less than 10 mm, relative to a virtual plane covering the opening. The antenna plane is preferably substantially parallel to an interior surface of the second housing part. The antenna is arranged so as to be able to transmit and receive signals through the non-electrically conductive part. By having an antenna plane substantially parallel to an inner surface of the second housing part which comprises the non-electrically conductive part or which can be entirely made of an electrically non-conductive material, it is possible to get good transmission / reception.

According to one embodiment, the luminaire further comprises a fixing base fixed at the opening of the first housing part, the second housing part being connected to the fixing base. A circumferential part of the first housing part (which circumferential part extends around the opening made in the first housing part) is preferably located between the second housing part and the fixing base. The second housing part is preferably provided with a screw thread, and the fixing base is provided with a corresponding screw thread allowing the second housing part to be screwed into the fixing base, the circumferential part of the first housing part preferably being between the second housing part and the fixing base.

To this end, the connection assembly may include a line for transmitting a power supply fault signal intended for the communication assembly. In this way, the communication circuit can take any required action before the total interruption of power to the communication circuit. Indeed, the power supply fault signal can be received by the communication circuit before the supply of electricity to the communication circuit is completely stopped, since there is a delay between the interruption of the main source d electricity (generally the sector) and the total stoppage of the communication circuit, due to the energy stored in the power supply and regulation assembly. On the other hand, the transmission of a supply fault signal, emitted when the power supply and light control assembly detects that the supply from the main source of electricity (generally the mains) is interrupted, can be very fast. The transmission of the supply fault signal can be carried out simply, eg. ex. by setting the line to a different voltage level when it has been detected that the supply from the main source of electricity has been interrupted. More particularly, the light supply and control assembly is designed so as to detect and communicate the supply fault before the end of the supply of electricity to the communication assembly.

According to one embodiment, the connection assembly comprises at least two supply lines and / or at least two data communication lines. The power lines are used to supply power from the power and light control assembly to the communication assembly. Preferably, the power supply and

For example, the communication circuit can be supplied with a voltage of 3.3 V. The at least two data lines can be used to communicate data between the communication assembly and the power supply and control assembly of the light, for example data from the light sensor or data received by the antenna.

According to one embodiment, the connection assembly can comprise a plug-in module, also called an electronic key, designed to be inserted in a housing of the power supply and light control assembly.
