Description

FUNCTIONAL HEAD SYSTEM AND METHOD FOR SECURING THE SAME

FIELD OF INVENTION

The present invention relates to functional heads, such as lununaire heads, and methods. Particular embodiments relate to a functional head system, such as a luminaire head system, and a method for securing the functional bead system to a support,

BACKGROUND

Generally, a functional head, such as a luminaire head, can be fixed to a support, e.g. a wall or a pole, using conventional fastening means such as screws or bolts and associated nuts. Especially for heavy functional heads, said conventional way of fixing a functional head to a support may lead to a difficult and unstable mounting of the functional head for the operator or user on site. In addition, said conventional fastening means may not be designed to carry the weight of the functional head 1n a secure way.

In the commonly used outdoor luminaires, the luminaire head angle, defined as the angle between the luminaire head and a support, such as a wall or the end of a pole connecting said luminaire head, ts fixed, or is inconvenient to adjust. Therefore, the light distribution of the outdoor luminaire is not adequately adjustable according to the characteristics of the environment to be lighted, such as the width of a road. Hence, it is necessary to manufacture outdoor luminaires of different inclinations corresponding to different luminaire head angles. according e.g. to the width of different road surfaces or the height of the luminaire head, thereby increasing the manufacturing

ZS costs.

SUMMARY

An object of embodiments of the mvention is lo provide a functional head system, such as a

Juminaire head system. More in particular, embodiments of the invention aim at providing a functional head system, such as a luminaire head system, which can be secured to a support, such as a wall or a pole, in a convenient and robust way, and for which at least one rotation angle can be adjusted on site, depending on the site to be monitored, sensed, or illuminated and/or the specific application. In addition, embodiments of the invention provide a method for securing such a functional head system to such a support. Embodiments of the invention also provide a method for adjusting at least one orientation of such a functional head system when secured to such a support.

According to a first aspect of the invention, there is provided a functional head system, such as a luminaire head for a luminaire, preferably an outdoor luminaire. Said functional head system comprises a connector base configured to be secured to a support, such as a wall or a pole, and a functional head configured to be releasably mounted on the connector base by means of a biunigue fitting mechanism defining a kev profile. The functional head system is configured to enable at least one rotational movement of at least a portion of the functional head when the functional head is mounted on the connector base.

Embodiments of the invention are based infer alia on the insight that, in conventional systems, the functional head. such as a himmaire head. may be first secured to a mounting base by means of at least one first screw, and subsequenily the entire functional head, ie, also comprising the mounting base, may be secured to a support. such as a wall or a pole, by means of at least one further screw or a bolt and corresponding nut. This may result 1n functional heads that may be significantly heavy, thereby leading to a difficult and unstable mounting thereof on e.g. a wall ora pole for the operator or user on site. In addition, a structure of the functional head and/or of the support may be damaged, especially in the case of heavy functional heads, because said first screw carries a substantial part of the weight of the functional head. Therefore, there is a risk of damage or even breakage of said first screw. This applies to luminaire head systems as well as tc other functional head systems, for example systems comprising a camera, an antenna, a loudspeaker, or any Sensor.

Embodiments of the invention are based infer alia on the further insight that, in conventional systems, an angle of the functional head may simply not be adjustable, or may be inconvenient to adjust, especially in the case the entire functional head, 1e the functional head housing and all its components, may be orientable with respect to a support, such as a wall or a pole. As mentioned above, this may result in orientable functional heads that may be significantly heavy, thereby leading to a difficult and unstable mounting thercof on e.g. a wall or a pole for the operator or user on site. Thus, in the case of a laminaire head system, the light distribution of conventional

Juminaires is not adequately adjustable according to the characteristics of the environment to be lighted, such as the width of a road. This also applies to systems other than luminaire head systems. for example functional head systems comprising 2 camera. an antenna, a loudspeaker, or any sensor, for which a field of view (FOV), or a sensing and/or emitting direction, is not adequately adjustable according to the characteristics of the environment to be sensed, monitored, or targeted.

In the functional head system of embodiments of the invention, the functional head is configured to be releasably mounted on the connector base by means of a biunigue fitting mechanism defining a key profile.

In the context of the invention, the term “biunique fitting mechanism” should be construed as a mechamsm enabling a one-to-one correspondence of shapes, dimensions, and orientation of a portion of the functional head and the connector base at a connection interface between the functional head and the connector base. The wording “mechanism” implies a mechanical connection between the portion of the functional head and the connector base at said interface. By “one-to-one correspondence”, it is meant that to cach shape, dimensions, and orientation of the portion of the functional head at said connection interface corresponds a shape, dimensions, and orientation of the connector base, and vice versa, In other words, shapes, dimensions, and orientation of the connector base are configured to match shapes, dimensions, and orientation of the portion of the functional head at said connection interface. In addition, any variations in the shape and dimensions of the portion of the functional head at said connection interface imply corresponding variations in the shape and dimensions of the connector base, and vice versa. This is mplied by the wording “biunique”. which means thai shapes, dimensions, and orientation of the portion of the functional head and the connector base at said connection interface are unique to one another. This is also implied by the wording “fitting”, which is a synonym of “matching”, and which means that the shapes, dimensions, and orientations of the portion of the functional head at said connection interface and the connector base are complementary.

Further, in the context of the invention, the term “key profile” should be construed in accordance with the construction of the wording “biumgue fitting mechanism”, as a profile having a shape of a key. By “kev”, it is meant that two elements presenting such a profile have complementary shapes and dimensions so as to form together a biumigue fitting mechanism, as defined above. In other words, the portion of the functional head at said connection interface and the connector base presenting such a key profile have complementary shapes and dimensions so as to form together the biunique fitting mechanism,

Therefore, in the functional head system of the invention, because the connector base can be first secured to the support, e.g. by means of screws or bolts and associated nuts, and subsequently the functional head can be releasably mounted on the connector base by means of the above-defined biunigue fitting mechanism, this leads to 2 more convenient and more stable mounting thereof on e.g. a wall or a pole for the operator or user on site than in conventional systems.

In addition, the above-defined biunique {iting mechanism is able to carry a substantial part of the weight of the functional head. Because said biunigue fitting mechanism can be designed to be more robust than a mere screw, such as the above-mentioned at least one first screw used in conventional systems, the risk of damage or even breakage of said biunique fitting mechanism 18 reduced, thereby reducing the risk that a structure of the functional head and/or of the support be damaged.

Moreover, in the functional head system of embodiments of the invention, the functional head system is configured to enable at least one rotational movement of at least a portion of the functional head when the functional head is mounted on the connector base. In other words, at least onc supplementary degree of freedom is enabled by the functional head system of the invention.

Therefore, the fixation of the functional head system to the support is improved, whilst a stable and adjustable rotation of at least a portion of the functional head is enabled m a plurality of positions corresponding to different orientations of the functional head. Hence, a more convenient. stable, and robust mounting of the functional head is provided, especially if tt is significantly heavy.

Preferred embodiments relate to a luminaire head for an outdoor luminaire. By outdoor luminaire, it is meant luminaires which are imsialled on roads, tunnels, industrial plants, stadiums, airports, harbors, rail stations, campuses, parks, cycle paths, pedestrian paths or in pedestrian zones, for example, and which can be used notably for the lighting of an outdoor arca, such as roads and residential areas in the public domain, private parking areas, access roads to private building infrastructures. warehouses, mdusiry halls, etc.

The above-mentioned biunigue fing mechanism and key profile will be further defined and described in the following embodiments,

According to a preferred embodiment, the connector base comprises a cavity, and the functional head comprises a connector configured to contact the connector base. Said connector comprises an insert element having a shape configured to fit a shape of the cavity.

According to an exemplary embodiment, the connector base comprises a recessed flange and a surrounding wall defining the cavity, and the insert element is configured to be accommodated within said recessed flange.

According to a preferred embodiment, said cavity and said insert clement define together said biunique fitting mechanism, and said shape of the cavity and said shape of the insert element define together said key profile.

According to a preferred embodiment, the key profile has at most one symmetry axis.

Preferably, a shape of the insert element may be designed symmetrically with respect to the symmetry axis. For example, a shape of the insert clement may comprise protrusions arranged symmetrically with respect to the symmetry axis of the insert element. It should be clear to the skilled person that other shapes of the insert element may be envisaged.

Preferably, a shape of the recessed flange may be designed symmetrically with respect to the symmetry axis. For example, a shape of the recessed flange may comprise corresponding recesses arranged symmetrically with respect to the symmetry axis of the recessed flange. It should be clear to the skilled person that other shapes of the recesses may be envisaged. provided that the shapes and dimensions of said recesses match the shapes and dimensions of said protrusions according to the above-mentioned one-to-one correspondence.

In this way, a single position and orientation for mounting and unmounting the functional head onffrom the connector base may be provided. In some embodiments. the key profile may have no symmetry axis, For example, one protrusion of the insert element may have a dimension and/or an orientation different from the other protrusions. It should be clear to the skilled person that, in other embodiments, the key profile may have more than one symmetry axis, for example two symmetry axes, Thus, in said embodiments, the functional head may be mouried/unmounted on/from the

Z5 connector base in two different relative positions and orientations in accordance with the key profile.

According to an exemplary embodiment, the connector base and the connector have a substantially circular outer shape. and an outer diameter of the connector base is substantially equal to an outer diameter of the connector.

In this way, a suitable connection interface between the funcional head and the connector base is provided, in particular between the connector of the functional head and the connector base. Also, a contact surface between the connector of the functional head and the connector base is optimized.

According to a preferred embodiment, said at least one rotational movement comprises a first rotational movement of the functional head with respect to the connector base, preferably over at least 180°, more preferably over more than 270°,

In other words, the biunique fitting mechanism that connects the functional head and the connector base is different from a so-called “twist and lock” mechanism in that the latter mechanism implies io lock the functional head to the connector base, 1.2, to secure the functional head io the connector base. Indeed, the wordings “lock” and “sccure” mean that pressure is applied onto the functional head and the connector base so as to firmly connect them and maintain them in contact with each other. By contrast, in the functional head system of embodiments of the invention, at least one rotational movement of at least a portion of the functional head is enabled by the functional head systern when the functional head is mounted on the connector base. In other words, at least one supplementary degree of freedom 1s enabled by the functional head system of the invention with respect to a functional head system wherein a conventional twist and lock mechanism is used.

Therefore, a fine adjustment of the angle of the functional head is enabled with respect to the connector base over a sufficiently large angular range, thereby providing a functional head for which the rotation angle can be conveniently adjusted on site, depending on the site to be sensed, monitored, targeted, or illuminated in the case of a luminaire head system, and/or the specific application and/or the characteristics of the environment to be sensed, monitored, targeted, or lighted 10 the case of a luminaire head system, such as the width of a road.

Accordmg to an exemplary embodiment, the connector base comprises a first fastening means, preferably at least one first screw, more preferably at least two first screws, configured to block

Z5 said first rotational movement. 1 should be clear to the skilled persons that, in other embodiments, other kinds of first fastening means may be envisaged to block said first rotational movement.

Thus, after rotating the functional head with respect to the connector base by a given angle, the functional head may be fixed to the connector base at a given position by said first fastening means. Said first fastening means only need to block said first rotational movement, not to finaly secure the functional head to the connector base. Thus, 19 the case of screw(s) used as a fastening means, said at feast one first screw need not be robust.

According to a preferred embodiment, said at least one rotational movement comprises a second rotational movement of the functional head with respect to a rotation axis parallel to a plane defined by the connector base, preferably over substantially 180°,

The connector base may have a substantially cvlindrical shape, having a first surface substantially circular, a second surface substantially circular opposite said first surface, and a peripheral surface substantially annular between said first and second surfaces. Thus, each of said first and second surfaces may define a plane, and the rotation axis may be defined as an axis parallel to said plane.

Thus, at least a portion of the functional head may be rotated with respect to the connector and the connector base around the above-defmed rotation axis, in order to adjust on sile, in the casc of a laminaire head system, the light distribution of the luminaire head according to characteristics of an environment to be lighted, depending on the site to be iluminated and/or the specific application, or in order to adjust the FOV or the sensing and/or emission direction of other functional head systems, Preferably, substantially the entire functional head. i.e, all portions of the functional head other than the connector, may be rotated with respect to the connector and the connector base around the above rotation axis,

According to an exemplary embodiment, the functional head comprises a second fastening means, preferably at least one second screw, more preferably at least two second screws, configured to block said second rotational movement. It should be clear to the skilled persons that, in other embodiments. other kinds of second fastening means may be envisaged to block said second rotational movement.

Thus, after roiating at least the portion of the functional head with respect to the connecior and the connector base by a given angle, the functional head may be fixed to the connector and the connector base at a given position by said second fastening means.

According to a preferred embodiment, the connector comprises a protruding portion on a side thereof opposite the connecior base, and the functional head further comprises a rotary portion configured to rotate with respect to the protruding portion.

According to an exemplary embodiment, said second fastening means, preferably said at least one second screw, extends through the protruding portion and the rotary portion,

According to a preferred embodiment, the protruding portion is provided with a first channel configured to receive an electrical wire extending from the connector base, and the rotary portion is provided with a second channel configured to guide said wire to the inside of the functional head.

In this way. an electrical wire for feeding the functional head with power and/or data signals may be suitably arranged, whilst enabling said second rotational movement of the functional head.

According to a preferred embodiment, the connector base comprises a through-hole and/or a peripheral recess for receiving an electrical wire extending between the support and the functional head.

As an example, the electrical wire may extend through the connector base via the through-hole. In the former example, the electrical wire coming from a rear side of the connector base may enter the connector base via the through-hole and exit the connector base towards the functional head via a front side of the connector base.

As another example, the electrical wire may extend via the peripheral recess provided to the connector base but not through the connector base, although a through-hole 1s provided to the connector base. In the latter example, an clement of the connecior base covering the peripheral recess may be removed lo have access to the peripheral recess. so that the electrical wire coming from a lateral side of the connector base can enter the connector base via the peripheral recess and exit the connector base towards the functional head via a front side of the connector base.

In this way, an electrical wire for feeding the functional head with power and/or data signals may be suitably arranged in two different configurations, whilst enabling said first rotational movement of the functional head.

According to a preferred embodiment, the functional head comprises a functional module and a gear module provided with means for driving the functional module. The functional module may comprise any one of a hight source, an image sensing means such as a camera, a communication means such as an antenna, a sensing means such as an air quality sensor or a smoke sensor or a microphone, a loudspeaker, a hight projecting means such as a projector, a display, or a laser. The camera may correspond to a closed-circuit television (CCTV) camera. The light projecting means may be configured to project images, logos, photos, texts, and the like. Signals may be sent to and/or from the communication means via a wireless network operating over short-range or long- range communication, e.g Bluetooth, Wi-Fi, Zigbee, LORA (ToT), IR, cellular, or via a wired network, ¢.g. Ethernet, DALI DMX, RS485, USB.

According to a preferred embodiment, the functional head comprises a light module provided with a light source. and a gear module provided with a light sowrce driving means.

According to a preferred embodiment, said at feast one rofational movement comprises a third rotational movemeni of the functional module with respect to the gear module, preferably over substantially 180°.

Thus, the functional module may be rotated with respect to the gear module in order to adjust on site the light distribution of a luminaire head according to characteristics of an environment to be lighted, depending on the site to be illuminated and/or the specific application, or in order to adjust the FOV or the sensing and/or emission direction of other functional head systems.

According to an exemplary embodiment, the functional head comprises a third fastening means, preferably at least one third screw, more preferably at least two third screws, configured to block said third rotational movement. It should be clear to the skilled persons that, in other embodiments, other kinds of third fastening means may be envisaged to block said third rotational movement,

According to a preferred embodiment, the functional head comprises a frame arranged between the functional module and the gear module, said frame being connected to the functional module and configured to enable said third rotational movement.

According to an exemplary embodiment, said frame comprises a curved groove, preferably a semi- circular groove, and the functional module comprises a pin extending in said curved groove and configured to move along said curved groove during said third rotational movement.

According io a preferred embodiment, the functional head further comprises an annular ring configured to be connected to the functional module and to contact the frame, and the frame is configured to be arranged between said anmlar ring and the functional module,

In order to enable said third rotational movement, the third fastening means may be unfastened, thereby releasing the pressure exerted by the functional module and the annular ring on the frame.

Indeed, when said third fastening means is fastened to the rear portion of the functional head, in particular to the rear portion of the gear housing, the frame may be fastened between a rear side of the functional module, for example a rear side of a light support such as a PCB m the case of a light module, and the annular ring.

Upon release of said pressure, a gap may be created between the frame and the functional module, in particular the light support. Another gap may be created between the frame and the annular ring,

Hence, the functional module may be free to rotate with respect to the gear module, and in particular with respect to the frame. The pin of the functional module, which extends in the sem- circular groove of the frame, may move along said groove during said third rotational movement.

DESCRIPTION OF THE EMBODIMENTS

Figures 1A and 1B respectively illustrate a perspective view and an exploded view of a luminaire head system in a mounded stake according to an exemplary embodiment,

As illustrated in Figures 1A and 1B, there is provided a luminaire head svstern 10 for a luminaire, preferably an outdoor lwsinaire. The luminaire head system 10 comprises a connector base 11 configured to be secured to a support, such as a wall (not shown) or a pole (not shown; see pole P in Figures 5A and SB). and a Juminaire head 12 configured to be releasably mounted on the connector base 11. It is noted that the connector base 11 of the embodiment of Figures 1A and IB is particularly adapted to be secured to a wall, such as a vertical wall or a ceiling, although not limited thereto. Indeed, said connector base 11 may also be adapted to be secured to a pole having a flat surface, such as a pole having a rectangular or a square cross-section, or the like. The connector base 11 may be secured to the support, preferably to the wall, using screws, for example three screws (see corresponding holes provided to the connector base 11 m Figure 2B).

Although not explicitly illustrated in Figures 1A and 1B, the luminaire head 12 is configured to be releasably mounted on the connector base il by means of a biunigue fitting mechanism defining a key profile.

In the context of the invention, the term “biunique fitting mechanism” should be construed as a mechamsm enabling a one-to-one correspondence of shapes, dimensions, and orientation of a portion of the tuminaire head 12 and the connector base 11 at a connection interface between the luminaire head 12 and the connector base 11. The wording “mechanism” implies a mechanical connection between the portion of the luminaire head 12 and the connector base 11 at said interface. Bv “one-to-one correspondence”, it is meant thal to cach shape, dimensions. and orientation of the portion of the luminaire head 12 at said connection interface corresponds a shape and dimensions of the connector base 11, and vice versa. In other words, shapes, dimensions, and orientation of the connector base 11 are configured to match shapes, dimensions, and orientation of the portion of the luminaire head 12 at said connection interface. In addition, any variations in the shape and dimensions of the portion of the hmminaire head 12 at said connection interface imply corresponding variations in the shape and dimensions of the connector base 11, and vice versa.

This is implied by the wording “biunique”, which means that shapes, dimensions, and orientation of the portion of the luminaire head 12 and the connector base 11 at said connection interface are unique to one another. This is also implied by the wording “fitting”, which is a synonym of “matching”, and which means that the shapes, dimensions, and orientation of the portion of the homnaire head 12 at said connection interface and the connector base 11 are complementary.

Further, in the context of the invention, the term “key profile” should be construed in accordance with the construction of the wording “biunigue fitting mechanism”, as a profile having a shape of a key. By “kev”, it is meant that two elements presenting such a profile have complementary shapes and dimensions so as to form together a biunique fitting mechanism, as defined above. In other words, the portion of the luminaire head 12 af said connection interface and the connector base 11 presenting such a key profile have complementary shapes and dimensions so as to form together the biunique fitting mechanism,

The above-mentioned bionigue fitting mechanism and key profile will be further defined and described in the following, in relation with Figures 2A and 2B, 34, and 5B.

The light cover 1213 may comprise a transparent or translucent portion. Optionally, a color filter may be arranged between the light source 1121 and the transparent or translucent portion of the light cover 1213. For example, the color filter may be a sheet arranged above the fransparent or translucent portion. The color filter is configured to absorb a portion of the light emitied by the light source in specific wavelength ranges so as to change the color of the light emitted by the luminaire head 12. Preferably, the color filter is accessible by opening the luminaire head 12, in particular the light module 121. In that way, the color filter can be easily changed. c.g. when it 1s desirable to change the color of the emitted hight Tor a special occasion or festivity.

The light source 1211 may comprise a light support 1214 {see Figure 1B), such as a PCB. on which a plurality of light emitting diodes (LEDs) is mounted. The LEDs may be arranged in an array of multiple colurans and rows. The light source 1211 may comprise RGB and/or RGBW and/or

RGBA LEDs and associated control circuitry for controlling the color and/or the color temperature emitted by the light source 1211.

Thus, the overall light color and/or light pattern and/or light tensity of the huminaire head 12 may vary.

The gear module 122 may comprise a gear support (not shown; see gear support 1224 m Figure 4B and Figures 12A and 12B) on which the light source driving means 1221 may be arranged, and a gear housing 1222, Although not explicitly illustrated in Figures 1A and 1B. the gear module 122 may comprise any one or more of the following: a light source dimming means, surge protection circuitry, electrostatic discharge (ESD) protection circuitry, connecting means, a fuse, a metering circuitry, a driving and/or control circuitry for any electrical components of the luminaire head 12.

As illustrated in Figures 1A and IB, the luminaire head 12 may comprise a housing wherein the light source 1211, the clectrical/clectronic components, and optionally a beat sink and a flux exhauster are arranged. The above-mentioned transparent or translucent portion facing the light source 1211 may be part of the housing, Preferably, the hight cover 1213 and the housing form a sealed housing. In the embodiment of Figures 1A and 1B, the housing comprises three portions, namely the light cover 1213, the light housing 1212, and the gear housing 1222,

In the embodiment of Figures 1A and 1B. the light cover 1213 has a substantially cylindrical shape, the transparent or translucent portion has a substantially circular shape, and the light support 1214 on which the pharality of LEDs is mounted has a substantially circular shape. Further, the light housing 1212 and the gear housing 1222 have a substantially tronconical shape. Thus, the overall shape of the housing of the luminaire head 12 is a truncated cone. In other embodiments, the overall shape of said housing may correspond to a cylinder.

It should be clear to the skilled person that the function, configuration, and arrangement of the features described above for the luminaire head system 10 of Figures 1A and IB also apply to functional head systems different from said luminaire head system 10. In said other functional head systems, the functional head may comprise any one of an image sensing means such as a camera. a communication means such as an antenna, a sensing means such as an air quality sensor or a smoke sensor or a microphone, a loudspeaker, etc.

Figures 2A and 2B respectively illustrate a perspective view of a luminaire head and a connector base of a luminaire head system in an unmounted state and a perspective view of the connector base alone according to the exemplary embodiment of Figures 1A and 1B.

As illustrated in Figures 2A and 2B, the luminaire head system 10 comprises a connector base 11 configured to be secured to a support, preferably a wall (not shown), such as a vertical wall or a ceiling, and a luminaire head 12 configured to be releasably mounted on the connector base 11, as described above in connection with Figures 1A and 1B. The luminaire head 12 may comprise a light module 121 provided with a light source 1211, and a gear module 122 provided with a light source driving means (not shown; sce light source driving means 1221 in Figure 4B). The light module 121 may comprise a light housing 1212 and a light cover 1213 covering the light source 1211 and configured to be releasably attached to the light housing 1212. The gear module 122 may comprise a gear support {not shown; see gear support 1224 in Figure 4B and Figures 124 and 125) on which the light source driving means 1221 may be arranged, and a gear housing 1222.

As illustrated in Figures 2A and 2B, the luminaire head 12 is configured io be releasably mounted on the connector base 11 by means of a biunique fitting mechanism defining a key profile, as defined above in connection with Figures 1A and 1B. The connector base 11 may comprise a cavity C. and the luminaire head 12 may comprise a connector 123 configured to contact the connector base 11. The connector 123 may comprise an insert element [ having a shape configured to fit a shape of the cavity C. The connector base 11 may comprise a recessed flange 111 and a surrounding wall 112 defining the cavity C. The insert element 1 may be configured to be accomodated within said recessed flange 111, with dimensions of the insert clement I matching dimensions of the recessed flange 111. Said cavity C and said insert element I may define together said bisnigue fitting mechanism, and said shape of the cavity C and said shape of the insert clement | may define together said key profile. The key profile may have at most one symmetry axis A, as illustrated 1n Figures 2A and 2B.

In the embodiment of Figure 2A. a shape of the insert element I comprises three protrusions that are arranged symmetrically with respect to the symmetry axis A of the msert element I It should be clear to the skilled person that other shapes of the inseri clement 1 may be envisaged. As illustrated in Figure 2A, the insert element I may be provided as a separate element which can be releasably fixed to the fupunaire head 12, m particular to the connector 123, e.g via two screws.

Thus, the insert element 1 may be easily replaced, and another insert element I having the same or a different shape may be fixed to the huminaire head 12. In addition, the insert clement I may be unfastened from the luminaire head 12, flipped by 180° in order to change the orientation of the key profile. and fixed again to the lominaire head 12. It should be clear to the skilled person that, in other embodiments, such as the embodiments of Figures 3A and 3R, the msert element | may be mtegrally formed with the luminaire head 12, in particular with the connector 123, e.g. by casting the connector 123,

Further, in the embodiment of Figure 2B, a shape of the recessed flange 111 comprises three corresponding recesses that are arranged symunetrially with respect to the symmetry axis A of the recessed flange 111. It should be clear to the skilled person that other shapes of the recesses may be envisaged, provided that the shapes and dimensions of said recesses match the shapes and dimensions of said protrusions according to a one-to-one correspondence.

Ag illustrated in Figure 2A, the connector base 11 and the connector 123 may have a substantially circular outer shape, and an ouier diameter of the connector base 11 may be substantially equal to an outer diameter of the connector 123. The connector 123 may comprise a protruding portion 1231 on a side thereof opposite the connector base 11, and the luminaire head 12 may further comprise a rotary portion 124 configured to rotate with respect to the protruding portion 1231.

As iflustrated m Figure 2B, the connector base il may comprise a through-hole H and/or a peripheral recess R for receiving an electrical wire (not shown, see electrical wire W m Figure 3B) extending between the support and the luminaire head 12. More details of the configuration and arrangement of the electrical wire within the connector base 11 are illustrated in Figure 3B.

Although not explicitly illustrated in Figures 2A and 2B. the luminaire head system 10 is configured to enable at least one rotational movement of at least a portion of the luminaire head 12 when the Tuminaire head 12 is mounted on the connector base 11. Said at least one rotational movement may comprise a first rotational movement of the luminaire head 12 with respect to the connector base 11, preferably over at least 180°, more preferably over more than 270°,

Due to the respective shapes and dimensions of the insert element | and the cavity C, in particular of the recessed flange 111, described above, the luminaire head 12 may be mounted on the connector base 11 by inserting the insert element I into the cavity C in a relative position and orientafion in accordance with the key profile of the above-defined biunigue fitting mechanism.

Once mounted on the connector base 11, the luminaire head 12 may be rotated with respect to the connector base 11 mm order to adjust on site the light distribution of the luminaire head 12 according io characteristics of an environment to be lighted, depending on the site to be illuminated and/or the specific application. This rotation 1s enabled by the above-described biunigue fitting mechanism. The rotation of the luminaire head 12 with respect to the connector base 11 may be performed preferably over at least 180°, more preferably over more than 270° even more preferably over substantially 360°. The maximum rotation angle of the Juminaire head 12 with respect to the connector base 11 may depend on the arrangement and/or dimensions of the above- mentioned electrical wire W, and/or the number of electrical wires W extending between the support and the luminaire head 12. Indeed, a torsion is exerted on said electrical wire(s) W during a rotation of the hunisaire head 12 with respect io the connector base 11. Thus, a maxuual torsion that the electrical wire(s) W can undergo may limit the maximal rotation angle possible of the homnaire head 12 with respect to the connector base 11.

After rotating the luminaire head 12 over 360° with respect to the connector base 11. the luminaire head 12 may be umnounted from the connector base 11, as the orieniation of the insert element matches the orientation of the recessed flange 111 at that specific position, In order io only provide a single position and orientation for mounting and unmounting the luminaire head 12 on/from the connector base 11, the key profile may have at most one symmetry axis A, as illustrated in Figures 2A and 2B. In some embodiments, the key profile may have no symmetry axis. For example, one protrusion of the insert element { may have a dimension and/or an orientation different from the other protrusions. It should be clear to the skilled person that, in other embodiments, the key profile may have more than one symmetry axis, for example two symmetry axes. Thus, in said embodiments, the luminaire head 12 may be mounted/ unmounted on/from the connector base 11 in two different relative positions and orientations in accordance with the key profile.

As illustrated in Figure 2B, the connector base 11 may comprise at least two first screws SCI configured to block said first rotational movement. Thus, after rotating the luminaire head 12 with respect to the connector base 11 by a given angle, the luminaire head 12 may be fixed to the connector base IL at a given position by said at least two first screws SCI. Said at least two first screws SC1 only need to block said first rotational movement, not to {innly secure the luminaire head 12 to the connector base 11. Thus, said at least two first screws SCI need not be robust. The at least two first screws may extend through the connector base 11 via a peripheral surface of the connector base 11, and may contact the fuminaire head 12, in particular the connector 123, in order to block said first rotational movement. It should be clear to the skilled person that m other embodiments only one first screw SCI may be provided to the connector base 11, and thus that only one first screw SC1 may suffice to block said first rotational movement.

Figures 2C and 2D illustrate two detailed views of a connection interface between the luminaire head and the connector base according to the exemplary embodiment of Figures 1A and IB.

As illustrated in Figures 2C and 2D, the limmaire head 12 may comprise a connector 123 configured to contact the connector base 11. The connector 123 may comprise a protruding portion 1231 on a side thereof opposite the connector base 11, and the luminaire head 12 may further comprise a rotary portion 124 configured to rotate with respect to the protruding portion 1231.

Although not explicitly illustrated in Figures 2C and 2D, the luminaire head system iO is configured to enable at least one rotational movement of at least a portion of the luminaire head 12 when the lumimaire head 12 is mounted on the connector base 11. Said at least one rotational movement may comprise a second rotational movement of the luminaire head 12 with respect to a rotation axis A2 (see Figures 2C and 2D) parallel to a plane defined by the connector base 11, preferably over substantial 180° As illustrated in Figure 2D, the connector base Il has 2 substantially cylindrical shape, having a first surface substantially circular, a second surface substantially circular opposite said first surface, and a peripheral surface substantially annular

IO between said first and second surfaces. Thus, each of said first and second surfaces defines a plane, and the rotation axis A2 is defined as an axis parallel to said plane.

Thus, at least a portion of the luminaire head 12, m particular the light module 121 and the gear module 122, may be rotated with respect to the connector 123 and the connector base 11 m order to adjust on site the light distribution of the luminaire head 12 according to characteristics of an environment to be lighted, depending on the site to be illuminated and/or the specific application,

This rotation is enabled by the above-described protruding portion 1231 and rotary portion 124.

As illustrated in Figures 20 and 2D. the luminaire head 12 may comprise at least two second screws SC2 configured to block said second rotational movement. Said at least two second screws

SC2 may extend through the protruding portion 1231 and the rotary portion 124, A quarter-turn screw (not shown; see quarter-turn screw in ai least Figures 1A, 1B, and 2A) may cover said at least two second screws SC2, and may be removed in order to access said two second screws SC2 and further access an electrical wire (see below). The at least two second screws SC2 may be unfastened so as to rotate at least a portion of the luminaire head 12 by a given angle, and then fastened agam in order to block said second rotational movement.

As illustrated in Figure 2C, the protruding portion 1231 may be provided with a first channel CHI configured to receive an electrical wire (not shown; see electrical wire W in Figure 3B) extending from the connector base 11, and the rotary portion 124 may be provided with a second channel

CH? configured to guide said wire to the inside of the luminaire head 12. Ag illustrated in Figure 2D, the connecior base 11 may comprise a peripheral recess R for receiving said electrical wire,

Figures 3A and 3B respectively illustrate a detailed view of a connector and a perspective view of a connccior base receiving an electrical wire according to the exemplary embodiment of Figures

LA and 1B. The connector base 11 and the connector 123 illustrated in Figures 3A and 3B may correspond to the connector base 11 and the connector 123 dlustrated in Figures 2A and 2B.

Ag illustrated in Figures 3A and 3B, the connector base 11 may comprise a cavity C (Figure 3B), and the luminaire head 12 may comprise a connector 123 (Figure 3A) configured to contact the connector base 11. The connector 123 may comprise an insert element 1 (Figure 3A) having a shape configured to fit a shape of the cavity C (Figure 3B). The msert element | may be configured to be accommodated within the recessed flange 111 (Figure 3B), with dimensions of the insert element 1 matching dimensions of the recessed flange 111, As illustrated 1 Figure 3A, the insert element | may be fixed to the huminaire head, in particular to the connector 123, via two screws.

Thus, the insert element 1 may be easily replaced. and another insert element I having the same or a different shape may be fixed to the luminaire head. Said cavity C and said insert element I may define together said biunique fitting mechanism, and said shape of the cavity C and said shape of the insert element T may define together said key profile. The key profile may have at most one syrametry axis A, as illustrated in Figure 3A.

As illustrated m Figure 3B. the connector base 11 may comprise a through-hole H (both left-hand and right-hand sides of Figure 3B) and/or a peripheral recess R (right-hand side of Figure 3B) for receiving an clectrical wire W extending between the support and the luminaire head 12. As illustrated on the left-hand side of Figure 3B, as an example an electrical wire W extends through the connector base 11 via the through-hole H. In the former example, the electrical wire W coming from a rear side of the connector base 11 enters the connector base 11 via the through-hole H and exit the connector base 11 towards the luminaire head 12 via a front side of the connector base 11.

Alternatively. as illustrated on the right-hand side of Figure 3B, as another example an electrical wire W extends via the peripheral recess R provided to the connector base 11. but does not extend through the connector base 11 although a through-hole H is provided to the connector base 11. In the latter example, an element 113 of the connector base 11 covering the peripheral recess R may be removed to have access to the peripheral recess R, so that an electrical wire W coming from a lateral side of the connector base 11 can enter the connector base 11 via the peripheral recess R and exit the connector base 11 towards the luminaire head 12 via a front side of the connector base 11.

Figures 4A and 4B respectively illustate a perspective view of the inside of a luminaire head system according to two different exemplary embodiments.

As illustrated in Figures 4A and 4B, the luminaire head 12 may comprise a frame 125 arranged between the ght module 121 and the gear modale 122. The frame 125 may be connected to the light module 121 and may be configured to enable a third rotational movement of the light module 121 with respect to the gear module 122, preferably over substantially 180° Thus, the hight module 121 may be rotated with respect to the gear module 122 m order to adjust on site the light distribution of the luminaire head 12 according to characteristics of an environment to be lighted, depending on the site to be illuminated and/or the specific application. This rotation is enabled by the above-mentioned frame 125, which is described m more details in the following.

As illustrated in Figures 4A and 4B, the luminaire head 12 may comprise at least two third screws

SC3 configured to block said third rotational movement. The frame 125 may comprise at least two legs 1252 configured to be connected to said at least two third screws SC3, and said at least two third screws SC3 may be configured {9 secure the frame [25 msde the luminaire head 12. The frame 125 may be configured to be secured to the rear portion of the humisaire head 12. The frame 125 may comprise a curved groove 1251, preferably a semi-circular groove 1251, and the light module 121 may comprise a pin 1215 extending in said curved groove 1251 and configured to move along said curved groove 1251 during said third rotational movement,

In the embodiment of Figure 4A. components inside the gear module 122 have been omitied for the sake of clarity. However, it should be clear to the skilled person that the same components as those of Figures 1A and IB may be arranged in the gear module 122 of Figure 4A In Figure 4A, the gear housing 1222 has been illustrated in transparency for the sake of clarity, the contours thereof being drawn m dashed lines. The luminaire head 12 comprises two third screws SC3 configured to block said third rotational movement. Accordingly, the frame 125 comprises two legs 1252 configured to be connected to said two third screws SC3, and said two third screws SC3 may be configured to secure the frame 125 inside the luminaire head 12, to the rear portion of the luminaire head 12, 1m particular to a rear portion of the gear housing 1222.

In the embodiment of Figure 4B. components inside the gear module 122 have not been omitted, but the gear housing 1222 has not been drawn for the sake of clarity. However, it should be clear to the skilled person that the same gear housing 1222 as that of Figure 4A may be used in the embodiment of Figure 4B. The luminaire head 12 comprises three third screws 5C3 configured to block said third rotational movement. Accordingly, the frame 125 comprises three legs 1252 configured to be connected to said three third screws 503, and said three third screws SC3 may be configured to secure the frame 125 inside the luminaire head 12, to the rear portion of the farninaire head 12, in particular to a rear portion of the gear housing 1222,

The lummare head 12 may be available in different sizes, whilst the general shape my remain the same or similar. The embodiment of Figure 4A corresponds to a first size of the luminaire head 12, wherein two third screws 8C3 and two corresponding legs 1252 of the frame 125 are illustrated,

The embodiment of Figure 4B corresponds to a second size of the luminaire head 12, wherein three third screws SC3 and three corresponding legs 1252 of the frame 125 are illustrated. The second size of the laminaire head 12 may correspond to a size larger than said first size. Exemplary dimensions of the lnminaire head 12 will be provided in the following in connection with Figures

GA-65C.

As illustrated in Figures 4A and 4B, the luminaire head 12 may further comprise an annular ring 126 configured to be connected to the light module 121 and to contact the frame 125. The frame 125 may be configured to be arranged between said annular ring 126 and the light module 121. In order to enable said third rotational movement, the at least two third screws SC3 may be unfastened, thereby releasing the pressure exerted by the hight module 121 and the annular ning 126 on the frame 125. Indeed, when said at least two third screws 5C3 are fastened to the rear portion of the luminaire head 12, in particular to the rear portion of the gear housing 1222, the frame 125 is fastened between a rear side of the light module, for example a rear side of a light support 1214 such as a PCB, and the annular ring 126. Upon release of said pressure, a gap is created between the frame 125 and the light module 121, in particular the light support 1214. Another gap is created between the frame 125 and the annular ring 126. Hence, the light module 121 is free to rotate with respect to the gear module 122. and tn particular with respect to the frame 125, The pin 1215 of the light module 121, which exiends in the semi-circular groove 1251 of the frame 125, moves along said groove 1251 during said third rotational movement,

As illustrated m Figures 4A and 4B, the third rotational movement of the light module 121 with respect to the gear module 122 may be performed over substantially 180° thanks to the semi- circular groove 1251, In this way, the light source 1211, in particular the plurality of LEDs arranged on the light support 1214. may be oriented over substantially 180° in order to adjust on site the light distribution of the luminaire head 12 according to characteristics of an environment 10 be lighted, depending on the site to be illuminated and/or the specific application.

CH2 configured io guide said wire io the inside of the luminaire head 12. Two second channels

CH2 are illustrated in Figures 4A and 4B, cach for receiving an electrical wire W. Thus, two corresponding first channels CHI may be provided to the protruding portion 1231, cach for receiving one of said two electrical wires W. Alternatively, the protruding portion 1231 may be provided with a single, larger, first channel CHI configured to receive said two electrical wires W.

Figures 5A and 5B may correspond to the light module 121 and the gear module 122 illustrated in the embodiment of Figures 1A and IB.

As illustrated m Figure 5B. the luminaire head 12 is configured to be releasably mounted on the connector base 11 by means of a biunique fitting mechanism defining a key profile. The terms “biunigue fitting mechanism” and “key profile” should have the same meaning as in the embodiment of Figures 1A and IB. The connector base 11 may comprise a cavity C, and the lammaire head 12 may comprise a connector 123 configured to contact the connector base 11. The connector 123 may comprise an insert element | having a shape configured to fit a shape of the cavity C.

The insert clement | may be configured to be accommodated within said recessed flange 111, with dimensions of the insert element I matching dirnensions of the recessed flange 111. Said cavity C and said msert element I may define together said biunique fitting mechanism, and said shape of the cavity C and said shape of the insert element I may define together said key profile. The key profile may have at most one symmetry axis A, as illustrated in

Figure 5B. Compared to the embodiment of Figures 2A and 2B, said shape of the cavity C and said shape of the insert element I may be the same, or may be different as illustrated in Figure SB. In other words, Figure SB illustrates a kev profile which is different from the key profile illustrated in

Figures 2A and 2B. However, it should be clear to the skilled person that the same key profile may be defined in the embodiment of Figures 3A and 3B and in the embodiment of Figures 24 and 28.

In the embodiment of Figure 5B, a shape of the insert element T comprises three protrusions that are arranged symmetrically with respect to the symmetry avis A of the msert element | It should be clear to the skilled person that other shapes of the insert element I may be envisaged. As explained above, the shape and dimensions of said three protrusions are different from the shape and dimensions of the three protrusions of the insert element | according to the embodiment of

Figures 2A and 2B. As illustrated in Figure 3A. the insert element I may be integrally formed with the fuminaire head 12, in particular with the connector 123, e.g by casting the connector 123. It should be clear to the skilled person that, 1m other embodiments, such as the embodiments of

Figures 2A and 2B. the insert element | may be provided as a separate element which can be releasably fixed to the luminaire head 12, in particular to the connector 123, e.g. via two screws.

Further, in the embodiment of Figure 3B, a shape of the recessed flange 111 comprises three corresponding recesses that are arranged symunetrially with respect to the symmetry axis A of the recessed flange 111. It should be clear to the skilled person that other shapes of the recesses may be envisaged, provided that the shapes and dimensions of said recesses match the shapes and dimensions of said protrusions according to a one-to-one correspondence. As explained above, the shape and dimensions of said three recesses are different from the shape and dimensions of the three recesses of the recessed flange 111 according to the embodiment of Figures 2A and 2B.

As illustrated in Figures SA and SB. the luminane head 12 may comprise a connector 123 configured to contact the connector base 11. The connector base 11 and the connector 123 may have a substantially circular outer shape. at least at a connection interface between the connector base 11 and the connector 123, and an outer diameter of the connector base 11 may be substantially equal to an outer diameter of the connector 123, at least at said connection interface. Around sad connection interface, a shape of the connector base 11 may be elongated, as illustrated in Figures 5A and 5B. The connector base 11 may receive two screws which extend through the clongated portion of the connector base 11 in order to secure the connector base 11 to the pole P. Further, the connector 123 may comprise a protruding portion 1231 on a side thereof opposite the connector base 11, and the luminaire head 12 may further comprise a rotary portion 124 configured to rotate with respect to the protruding portion 1231.

Although not explicitly illustrated in Figures SA and 5B, the luminaire head system 10 is configured to enable at least one rotational movement of at least a portion of the luminaire head 12 when the luminaire head 12 1s mounted on the connector base 11. Said at least one rotational movement may comprise a first rotational movement of the luminaire head 12 with respect to the connector base 11, preferably over at least 180°, more preferably over more than 270°, as best illustrated in Figure SB. The connector base ll may comprise at least hvo first screws SCI configured to block said first rotational movemerd, as ülustrated m Figure SA. More details are found in the description of Figures 2A-2B.

Alternatively or in addition, said at least one rotational movement may comprise a second rotational movement of the luminaire head 12 with respect to a rotation axis (not shown; see tation axis AZ in Figures 2C and 2D) parallel to a plane defined by the connector base 11, preferably over substantially 186°, as best iilustrated m Figure SB and described in connection with

Figures 2C and 2D.

Alternatively or m addition, said at least one rotational movement may comprise a third rotational movement of the light module 121 with respect to the gear module 122, preferably over substantially 180°, as best illustrated and described in connection with Figures 4A and 4B.

Regarding said first rotational movement of the luminaire head 12 with respect to the connector base 11, the luminaire head 12 may be mounted on the connector base 11 by means of the biunique fitting mechanism by first inserting the luminaire head 12 into the connector base 11 in a first orientation in accordance with the kev profile, then by rotating the luminaire head 12 with respect to the connector base Il to a second orientation at an angle of substantially 180° from the first orientation. Starting from said second orientation, the luminaire head 12 may be further rotated with respect to the connector base 11, preferably over more than 90°, which provides a total range for the rotation angle of the luminaire head 12 which is preferably more than 270°,

Figure 5B illustrates a position of the luminaire head 12 according to said second orientation, but in an unmounted siate of the luminaire head 12 for the sake of clarity. In order io mount the luminaire head 12 as dlustrated in Figure SB to the connector base 11, the luminaire head 12 is first fipped by 180° io reach said first orientation in accordance with the key profile dlustrated in

Figure 5B, then the insert element | is inserted into the cavity C of the connector base 11, and then the luminaire head 12 is rotated to reach said second onentation at an angle of substantially 180° from the first orientation. Subsequently. starting from said second orientation. the Juminaire head 12 may be further rotated with respect to the connector base 11 to reach any desirable orientation of the luminaire head 12, preferably over more than 90°, which provides a total range for the rotation angle of the luminaire head 12 which is preferably more than 270°.

As illustrated in Figure 5B, the connector base 11 may comprise a through-hole H for receiving an electrical wire (not shown: see electrical wire W in Figure 3B) extending between the pole P and the luminaire head 12.

Indeed, the luminaire head system 10 illustrated in Figure 6D comprises a light housing 1212 having a curved cylindrical shape, as the luminaire head system 10 illustrated in

Figure 6C. It should be clear to the skilled person that other shapes of the light housing 1212, such as those illustrated in Figures 6A and 6B, may be used in combination with the light shield 1216 of

Figure 6D.

Ag illustrated in Figure 6D. the light shield 1216 may bave an asymmeirical shape. with a first height hl larger than a second height h2. Said first height hl may be at least two times larger than said second height h2, preferably at least three times larger, more preferably at least four times larger. In this way, the light distribution of the fwainaire head system may be modified, and light beams emitted from the light source may be redirected towards a preferential direction, e.g. a ground surface, a ceiling, or vertical wall surfaces, Indeed, a portion of the light shield 1216 having said first height hl intercepts and redirects more light rays emitted from the light source than a portion of the light shield 1216 having said second height h2.

Although not illustrated m Figure GD, the light shield 1216 may be fixed to the hight housing 1212 using the same fastening means as for the light cover 1213 (sce z.g, Figure 1A and Figures GA-6C).

For example, the light cover 1213 may be fixed to the light housing 1212 using at least two screws, e.g. four screws as illustrated in Figures 1A and GA. Thus. the light shield 1216 may be fixed to the

S light housing 1212 using said four screws. Said four screws may be arranged at substantially 90° from one another (sec Figures 1A and 6A), and the light shield 1216 may be provided with four corresponding holes {not shown) for receiving said four screws. In this way, the light shield 1216 may be fixed to the light housing 1212 in four different positions at an angle of substantially 90° from one another. Thus. duc to the asymmetrical shape of the light shield 1216, light beams omitted from the light source may be redirected towards four different directions corresponding to the four positions of the hight shield 1216, ¢.g. a ground surface, a ceiling, or vertical wall surfaces.

Common to all embodiments described above in relation to Figures 1A-6D, there is provided a method for scouring a functional head system, such as the luminaire head system 10 of any one of the above embodiments. to a support, such as a wall or the pole P of the above embodiments of

Figures SA and 3B. The method comprises securing the connector base 11 to the support, mounting the functional head 12 on the connector base 11 by means of the biunigue fitting mechanism, rotating at least a portion of the functional head 12, and blocking a rotational movement of at least said portion of the functional head 12.

The step of mounting the functional head 12 on the connector base 11 by means of the biumgue fitting mechanism may comprise inserting the functional head 12 into the connector base 11 ma first orientation m accordance with the key profile, and rotating the functional head 12 with respect to the connector base 11 to a second orientation at an angle from the first onieniation, preferably at an angle of at least 5° from the first orientation,

In this way, it is ensured thai the functional head 12 is correcily mounted on the connector base 11.

Indeed. the above-mentioned rotation of at least 5° ensures that the second orientation of the functional head 12. in particular of the insert element {, does not correspond to the orientation of the connector base 11, in particular of the recessed flange 111, and thus that the funcional head 12 may not be unmounted from the connector base 11 in said second orientation.

The step of rotating at least the portion of the functional head 12 may comprise any one or more of the following steps: rotating the functional head 12 with respect to the connector base 11, preferably over at least 180°, more preferably over more than 270°, as illustrated in Figures 7A-7B and BA-8B and explained above with respect to the embodiments of Figures 2A-2B and SA-SB,

rotating the functional head 12 with respect to a rotation axis A2 parallel to a plane defined by the connector base 11, preferably over substantially 180°, as explained above with respect fo the embodiment of Figures 20 and 2D, and rotating a functional module 121 of the functional head 12 with respect to a gear module 122 of the functional head 12. preferably over substantially 180°, ag explained above with respect to the embodiment of Figures 4A and 4B.

The method may further comprise, before mounting the functional head 12 on the connector base il by means of the biunigue fitting mechanism, the step of connecting an electrical wire W extending from the support to the functional head 12, as explained above with respect to the embodiments of Figure 3A,

Figures 7A and 7B illustrate a method for securing and orienting the luminaire head system 10 of the embodiments of Figures 1A-4B to a wall, such as a vertical wall or a ceiling.

As illustrated mn Figures 7A and 7B, the luminaire head 12 may be mounted on the connector base 11 by accommodating the sert element 1 of the connector 123 within the recessed flange 111 of the connector base 11 according to the biunigue fitting mechanism, In other words, the luminaire head 12 may be mounted on the connector base lt when an orientation of the insert clement 1 matches an orientation of the recessed flange 111, as illustrated in Figure 7A. Once mounted on the connector base 11, the luminaire head 12 may be rotated with respect to the connector base 11, preferably over at least 180°, more preferably over more than 270°, even more preferably over substantially 360°, as illustrated in Figure 7B. The luminaire head 12 may then be fixed in a given position corresponding to a given angle with respect to the connector base 11 by means of a suitable fastening means, e.g. at least one screw, preferably at least two screws SCL. The laminaire head 12 may be unmounted from the connector base 11 by rotating it in the opposite direction by said given angle. In addition, after a rotation of 360° with respect to the connector base 11. the furninaire head 12 may be unmounted from the connector base 11, as the orientation of the insert element matches again the orientation of the recessed flange 111.

Ag already mentioned above in connection with the embodiment of Figures 2A and 2B, the insert element I may be provided as a separate element which can be releasably fixed to the luminaire head 12, in particular to the connector 123, e.g. via two screws, Thus, the insert element Ì may be unfastened from the lominawe head 12, flipped by 180° in order to change the orientation of the key profile, and fixed again io the luminaire head 12, depending on the orientation of the connector base 11 when secured to the wall, on a position and orientation of the electrical wire exiting the wall and entering the connector base 11, and the desired final orientation of the luminaire head 12.

Thanks to the Tact that the insert element I may be flipped by 180° a flexibility 1s offered to the user or installer when mounting the luminaire head 12 on the connector base Il to achieve the desired final orientation of the luminaire head 12, without having to unfasten the connector base 11 from the wall and reorient it before securing it again to the wall, Indeed, the position and orientation of the electrical wite exiting the wall may prevent said reorientation of the connector base 11 with respect to the wall. it should be clear to the skilled person that the above method described in connection with Figures 7A and 7B also applies to functional head systems different from the luminaire head system 10 of the embodiment of Figures 2A and 2B. In said other functional head systems, the functional head may comprise any one of an image sensing means such as a camera. a communication means such as an antenna, a sensing means such as an air qualify sensor or a smoke sensor or a microphone, a loudspeaker, etc.

Figures 8A and 8B illustrate a method for securing and orienting the luminaire head system 10 of the embodiments of Figures 3A and SB to a pole P.

In embodiments wherein the luminaire head system 10 is configured to be secured to a pole B, such as in the above embodiments of Figures SA and 3B, the step of mounting the laminaire head 12 on the connector base 11 by means of the biunigue fitting mechanism may comprise inserting the

Iuminaire head 12 mto the connector base 11 in a first orientation 1n accordance with the key profile, and rotating the tuminaire head 12 with respect to the connector base 11 fo a second orientation at an angle from the first orientation, preferably at an angle of substantially 180° from the first orieniation.

As already mentioned above in connection with the embodiment of Figures 5A and 5B, the insert clernent | may be mtegrally formed with the luminaire bead 12, in particular with the connector 123, e.g. by casting the connector 123. Thus. contrary to the insert element I according to the embodiment of Figures 2A and 2B, the insert element illustrated in Figures 5A and 5B cannot be unfastened from the luminaire head 12, flipped by 180° in order to change the orientation of the key profile, and fixed again to the lurninaire head 12. As a consequence, two different methods for mounting and orienting the luminaire bead system 10 to the pole P are described in the following, depending on the desired final orientation of the luminaire head 12.

As illustrated in Figure 8A, the desired final orientation of the luminaire head 12 corresponds io a backwards illumination of the luminaire head 12, eg, towards a ground surface. Hence, the connector base 11 may be first secured {9 the pole P such that an orientation of the recessed {lange 111 matches an orientation of the insert element 1 when the luminaire head 12 1s oriented upwards.

The luminaire head 12 may thus be mounted on the connector base 11 in said upward orientation in accordance with the key profile. The luminaire head 12 may then be rotated with respect to the connector base 11 to a downward orientation at an angle of substantially 180° from the upward orientation. Once oriented according to said downward orientation, the luminaire head 12 may be further oriented by a given angle so as to achieve the desired final orientation, and subsequently fixed with respect to the connector base 11 by means of a suitable fastening means, e.g. at least one screw, preferably at least two screws SCL. The luminaire head 12 may be unmounted from the connector base 11 by rotating it in the opposite direction by said given angle and further by substantially 180°. In addition, after a rotation of 360° with respect to the connector base 11, the lammaire head 12 may be unmounted from the connector base 11, as the orientation of the insert element I matches again the orientation of the recessed flange 111.

As illustrated in Figure 8B, the desired final orientation of the luminaire head 12 corresponds to an upwards illummation of the luminaire head 12, e.g. towards a cething surface or a higher vertical surface of a building or the like, or towards the sky. Hence, the connector base Il may be first secured to the pole P such that an orientation of the recessed flange 111 matches an orientation of the insert element I when the luminaire head 12 is oriented dowmwards. The hwmnaire head 12 may thus be mounted on the connector base 11 m said downward orientation in accordance with the key profile. The luminaire head 12 may then be rotated with respect to the connector base 11 to an upward orientation af an angle of substantially 180° from the downward orientation, Once oriented according to said upward orientation, the luminaire head 12 may be further oriented by a given angle so as to achieve the desired final orientation, and subsequently fixed with respect to the connector base 11 by means of a suitable fastening means, c.g. at leasi one screw, preferably at least two screws SCI. The luminaire head 12 may be unmounted from the connector base 11 by rotating if in the opposite direction by said given angle and further by substantially 180°. In addition. after a rotation of 360° with respect to the connector base 11, the luminaire head 12 may be unmounted from the connector base 11. as the orientation of the insert element 1 matches again the orieniation of the recessed flange 111.

It should be clear ta the skilled person that the above method described in connection with Figures 8A and 8B also applies to functional head systems different from the luminaire head system 10 of the embodiment of Figures SA and 5B, such as those described above.

Figures 9A and 9B illustrate a method for orienting at least a portion of a functional head system with respect to another portion of the functional head system,

Ag illustrated in Figures 9A and 9B. the functional head system comprises a functional head 12 configured to be secured to a support, such as a wall or a pole. The functional head 12 comprises a functional module 121 and a gear module 122, such as the light module 121 and the gear module 122 described above. The functional head 12 comprises a front portion wherein the functional module 121 is arranged. and a rear portion wherein the gear module 122 is arranged. The functional module 121 18 configured to rotate with respect to the gear module 122 around a rotational axis A3 intersecting the functional module 121 and the gear module 122.

As illustrated in Figures 9A and 9B, the functional module 121 and the gear module 122 may have a rotational symmetric shape, preferably a cylindrical or tronconical shape, and the rotational axis

A3 may be a symmetry axis of the functional head 12. The rotational axis A3 may be perpendicular toa plane defined by the functional module 121. The rotational axis A3 may also be perpendicular to a plane defined by the gear module 122. The functional module 121 may be configured to rotate with respect to the gear module 122 by an angle of at least 90°, preferably by an angle of substantially 180°, 1e, by an angle of substantially 90° clockwise and by an angle of substantially 90° counterclockwise with respect to a reference position of the functional module 121 corresponding to an angle of 0° The functional head 12 may comprise a fastening means, preferably at least one screw, more preferably at least two screws SC3, configured to block said rotation of the functional module 121. Said rotation and said at least two screws SC3 may respectively correspond to the third rotational movement and the at least two third screws SC3 described above in connection with the embodiment of Figures 4A and 48. The at least two screws

SC3 may be unfastened, then the functional module 121 may be rotated with respect to the gear module 122 by a given angle, and the at feast two screws SC3 may be fastened again in order to block the rotation of the funcional module 121 at a desired position with respect to the gear module 122.

Although not illustrated in Figures 9A and 9B, the functional head 12 may comprise a frame arranged between the functional modale 121 and the gear module 1272, said frame being connected to the functional module 121 and configured to enable said rotation of the functional module 121

Said frame may correspond to the frame 125 described above in connection with the embodiments of Figure 1B and Figures 4A and 4B.

The functional module 121 may comprise any one of a light source, such as the light source 1211 illustrated in Figures 1A, ZA, and 5A, an image sensing means such as a camera, a communication means such as an antenna, a sensing means such as an air quality sensor or a smoke sensor or a microphone, a loudspeaker, a helt projecting means such as a projector, a display, or a laser, The camera may correspond to a closed-circuit television (CCTV) camera. The light projecting means may be configured to project images, logos, photos, texts, and the like. The functional module 121 may comprise a light source {see 1211 in Figures |A, 2A, and 5A) having an asymmetric hight distribution. For example, the light source may comprise lenses arranged over corresponding

LEDs, said lenses having an asymmetric shape so as to provide the light source of the luminaire head 12 with an asymmetric light distribution. Said asymmetric lenses may correspond to fice- form lenses. The lenses may be miegrally formed as a lens plate covering the LEDs of the hight source, In this way, by rotating the light module 121 with respect to the gear module 122 around said rotational axis A3, a light distribution of the luminaire head 12 may be adequately adjusted according to the characteristics of the environment to be lighted.

It should be clear to the skilled person that the above method described in connection with Figures

GA and 9B also applies to functional bead systems different from the luminaire head system 10 of the embodiments of Figures 2A-2B and Figures 3A-5B, such as those described above. In said functional head systems, the functional module 121 may comprise any one of an image sensing means such as a camera, a conununication means such as an antenna, a sensing means such as an at quality sensor or a smoke sensor or a microphone, a loudspeaker, etc, having an asymmetric field of view (FOV), or an asymmetric sensing and/or emitting direction. In this way, by rotating the functional module 121 with respect to the gear module 122 around said rotational axis A3, an

FOV or a sensing and/or emitiing direction the functional module 12 may be adequately adjusted according to the characteristics of the environment io be sensed, monitored, or targeted.

The above functional head system described in conneciion with Figures SA and 98 may correspond to the luminaire head system 10 of the embodiments of Figures 1A-8B. te, to a functional head system comprising a connector base 11 configured to be secured to a support, such asa wall or a pole, and a functional head 12 configured to be releasably mounted on the connector base 11 by means of the above-defined biunique fitting mechanism,

It should be clear to the skilled person that the functional head system of Figures SA and 9B may correspond to other functional head systems, e.g. to a functional head which is directly secured to a support, such as a wall or a pole, without the use of a connector base between the functional head and the support, or to a functional head system comprising a connector base configured to be secured to a support, such as a wall or a pole, and a functional head configured to be mounted on the connector base by other means than by means of said biumgue fitting mechanism. For example, the functional head may be mounted to the connector base by means of at least one screw or at least one bolt and corresponding nut, like 19 the conventional systems.

Figures 10A and 10B respectively illustrate perspective views of two luminaire head systems comprising different types of light sources. The light source 1211 of the embodiment of Figure 10A may correspond to the light source 1211 of the embodiment of Figure LA (“wall mount”) or

Figure 5A (“pole mount”).

As illustrated in Figure 10A, the light source 1211 may comprise a plurality of collimating clemenis 1217, such as anti-glare collimating elements, arranged an a support 1214 of the light module 121, such as a PCB. Each collimating element 1217 may be associated with a LED of the light source 1211. The plurality of LEDs may be arranged on the PCB 1214 following a concentric circular or a honcvcomb arrangement. As illustrated in Figure 10A, the plurality of collimating elements 1217 may also be arranged on the PCB 1214 following the concentric circular or the honevcomb arrangement, cach collimating element 1217 being configured to cover cach LED of the light source 1211. It should be clear to the skilled person that in other embodiments, collimating elements may be provided to only a subset of the plurality of LEDs.

The embodiment of Figure 10B differs from the embodiment of Figure 10A in that the type of light module 121 is different. As illustrated in Figure 10R, the light module 121 may have an asymmetric light distribution. For example, the light source 1211 may be associated with a plurality of lenses 1218 arranged over a corresponding plurality of LEDs. said plurality of lenses 1218 having an asymmetric shape to provide the hight source 1211 with an asymmetric light distribution. Said asymmetric lenses 1218 may correspond to free-form lenses. The plurality of lenses 1218 may be integrally formed as a lens plate covering the plurality of LEDs of the hight source 1211. As in the embodiment of Figure 10A, the plurality of LEDs may be arranged on the

PCB 1214. Contrary to the embodiment of Figure 104, as tllustrated in Figure 10B the LEDs may be arranged on the PCB 1214 following a two-dimensional array comprising a plurality of rows and columns. The plurality of lenses 1215 may also be aranged on the LEDs following the two- dimensional array, each lens 1218 being configured to cover cach LED of the light source 1211 It should be clear to the skilled person that in other embodiments, lenses may be provided to only a subset of the plurality of LEDs.

As illustrated in Figures 10A and 10B, the hight cover 1213 comprises a plurality of inlet apertures 1219, e.g four apertures arranged at substantially 90° from one another. The plurality of inlet apertures 1219 may be arranged at a vicinity of the screws used for fixing the light cover 1213 to the light housing 1212 (see above description with respect to Figure 6D). To each of the plurality of inlet apertures 1219 provided to the light cover 1213 may correspond a plurality of exhaust holes, or drain holes (not shown; see exhaust holes 12197 in Figure 1A, which are also visible in mast of Figures 1A-98) provided to the light housing 1212, m particular to a bottom portion of the light housing 1212. Each inlet aperture 1219 may communicate with each exhaust hole 1219” via one or more channels or grooves, such as the substantially circular peripheral channel 12197 illustrated in Figures 12A and 12B. In this way. the plurality of exhaust holes 12197 can evacuate water or dirt entering the one or more channels, such as the substantially circular peripheral channel 12197 of Figures 124 and 128, via the plurality of inlet apertures 1219, This means for draining or evacuating water or dirt is especially advantageous when the luminaire head system 10 is oriented upwardly, e.g towards a ceiling, a building, or the sky, such that rain or snow contacting the light cover 1213 when falling is evacuated from the huninaire head system 10 instead of staving in contact with the hight cover 1213 and forming a pool. Indeed. a shape and arrangement of the light cover 1213 and the light housing 1212 may define a recessed area, which can accumulate water if no draining or evacuating system is provided to the luminaire head system 10, thereby hindering the illumination of the lummatre head system 10. This also applies to functional head systems different from the luminaire head system 10 of the embodiments of

Figures 10A and 10B, such as those described above.

Figure 11A illustrates a perspective view of a luminaire head system comprising an external madule, The luminaire bead system 10 of the embodiment of Figures 11 A may correspond to the luminaire head system 10 of the embodiment of Figures 5A and 5B.

Ag illustrated in Figure 114A, the luminaire head system 10 comprises an external module 1223 mounted thereon, in particular on a bottom surface of the gear housing 1222. The external module 1223 may be plugged in a receiving means of the gear housing 1222. such as a receptacle, and may be removably fixed to the gear housing 1222. The external module 1223 may comprise different functionalities, such as control fonctionalities and/or sensing functionalities and/or communication functionalities. Preferably, the recepiacle, also called a socket, is one of a NEMA or Zhaga receptacle. and the external module is a control module configured to be plugged in such receptacle. The receptacle and the control module may be configured to be coupled through a twist-lock mechanism, e.g. as described in the above-mentioned ANSI C136.10-2017 standard or

ANSI C136.41-2013 standard or Zhaga Interface Specification Standard.

With respect to control functionalities, the external module 1223 may correspond to a luminaire controller configured to send control signals to electrical/electronic components inside the gear module 122, so as to control the driving of the light module 121 and to modify the hehtmg characteristics of the light source 1211 (light intensity such as dimming, light color, light color temperature, lighting pattern, hehting distmbution, light flashing, etc}. With respect to sensing functionalities, the external module 1223 may correspond to a sensor configured fo sense an environment of the luminaire head system 10, such as an ambient light sensor, a passive infrared (PIR) sensor, a presence Of occupancy Sensor, a movement sensor, an ait quality sensor, a smoke sensor, a microphone, etc. With respect to communication functionalities, the external module 1223 may correspond to an antenna configured to send and/or receive signals. It should be clear to the skilled person that said sensor and/or said antenna may be configured to communicate with electrical/slectronic components inside the gear module 122 by sending and/or receiving signals. It should also be clear to the skilled person that said external module 1223 may be provided to the lununaire head system 10 of the embodiments of Figures 1A and 1B, or to functional head systems different from said luminaire head system 10.

Figure 118 illustrates a perspective view of three lununaire poles, each comprising a plurality of luminaire head systems secured thereto. The plurality of luminaire head systems 10 of the embodiment of Figure 11B may correspond to the luminaire head system 10 of the embodiment of

Figures SA and 5B.

As illustrated in Figure 11B, each pole P comprises a plurality of luminaire head systems 10 secured thereto, one being arranged above the other along a longitudinal direction of the pole P.

The right-hand pole P of Figure 11B comprises a plurality of luminaire head systems 10 comprising a light housing 1212 having a shape as described in connection with Figure 6A. The central pole P of Figure 11B comprises a plurality of luminaire head systems 10 comprising a hight housing 1212 having a shape as described in connection with Figure 6B. The left-hand pole P of

Figure 11B comprises a plurality of luminaire head systems 10 comprising a light housing 1212 having a shape as described in connection with Figure 6C,

For cach of the three poles P, the luminaire beads 12 may be releasably mounted on then respective connector base 11 by means of the above-defined biunique fitting mechanism. The luminaire heads 12 may be rotated with respect to their respective connector base 11 as described in connection with Figures 8A and 8B. Alternatively or in addition, the luminaire heads 12 may be rotated as described in connection with Figures 2C and 2D. Alternatively or in addition, the light module 121 of the luminaire heads 12 may be rotated with respect to the gear module 122 of the faminaire heads 12 as described in connection with Figures 9A and 9B.

For each of the three poles P, different sizes of luminaire heads 12 may be secured to the pole P depending on their longitudinal position on the pole P. For example, luminaire heads 12 of the “maxi” size (see above) may be secured to a lower portion of the pole P, luminaire heads 12 of the “midi” size {see above) may be secured to an miermediate portion of the pole P, and luminaire heads 12 of the “mini” size {sec above) may be secured to an upper portion of the pole P. Each laminaire head 12 may be oriented differently from the others on the same pole P, or some luminaire heads 12 may have the same or similar orientation. The orientation of the luminaire heads 12 with respect to the pole P may depend on lighting characteristics to be achieved. Thus, the light distribution of each fuminaire head 12 can be adjusted on site according to characteristics of an environment to be lighted, depending on the site to be illuminated and/or the specific application. This also applies to functional head systems different from the lummaire head systems 10 of the embodiment of Figure 11B, such as those described above.

Ag illustrated in Figure 11B, for cach of the three poles P, at least two luminaire head systems 10 may comprise different types of light sources 1211 and/or optical elements. In an example, a first laminaire head system 10 may comprise a first light source 1211 having a plurality of collimating elements as described in connection with Figure 10A (see element 1217), and a second luminaire head system 10 may comprise a second hight source 1211 having a plurality of asymmetrical lenses as described m connection with Figure 10B (see element 1218). Thus, for cach of the first and second luminaire head systems 10, the light module 121 may be rotated with respect to the gear module 122, as described in connection with Figures 9A and 9B, to adjust on site the lighting characteristics of the laminaire head 12. This also applies to functional head systems different from the lominaire head systems 10 of the embodiment of Figure 11B, such as those described above.

Figures 12A and 12B respectively illustrate a cross-sectional view and an enlarged cross-sectional view of an interface between a helt module and a gear module of a luminaire head system.

Ag illustrated 1n Figures 12A and 12B. a first seal SI may be present between the hight module 121 and the gear module 122, In the case of light modules 121 and gear modules 122 having a substantially cylindrical or troncomcal shape, such as those illustrated in Figures 12A and 128, the first seal SI may correspond to a substantially circular peripheral seal Sl between respective peripheral portions of the light module 121 and the gear module 122. The first seal S1 may be arranged in a substantially circular peripheral groove 1225 of the gear module 122. A corresponding substantially circular peripheral protrusion 1215° of the light module 121 may be configured fo contact the first seal Sl in said peripheral groove 1225 to ensure water and dirt tightness of the luminaire head system 10 at a junction between the light module 121 and the gear module 122. A second seal S2 may be present between inside the light module 121, between the light cover 1213 and the light housing 1212. In the case of a light module 121 having a substantially cvlindrical or tronconical shape, such as the one illustrated in Figures 12A and 128, the second seal 82 may correspond to a substantially circular peripheral seal S2 between respective peripheral portions of the light cover 1213 and the light housing 1212. Similar groove and corresponding protrusion may be provided to the light housing 1212 and the heht cover 1213, respectively, to ensure water and dirt tightness of the luminaire head system 10 at a junction between the light cover 1213 and the light housing 1212.

As illustrated in Figures 12A and 12B, a substantially circular peripheral channel 12197 may hnk each inlet aperture (not shown; see inlet aperture 1219 in at least Figures [0A and 10B) with cach exhaust hole (not shown; sce exhaust hole 12197 in at least Figure 11A). In this way, the plurality of exhaust holes 12197 can evacuate water or dirt entering the peripheral channel 12197 via the plurality of inlet apertures 1219, The light housing 1212 may play the role of a beat sink for dissipation of heat generated by the light source 1211, via a metal plate 1214’ supporting the light support or PCB 1214.
