Description

CONNECTOR FOR ATTACHING A LUMINAIRE HEAD TO A POLE AND LUMINAIRE

WITH THE SAME

FIELD OF INVENTION

The field of the invention relates to a connector for attaching a component, such as a luminaire head, to a base support, such as a pole, a luminaire head that cooperates with said connector and a luminaire comprising the connector and the luminaire head.

BACKGROUND

Environmental concerns, power usage concerns, security concerns have led to luminaires with a light distribution tailored to the application. More in particular, optics have been developed to shape the distribution of the light emitted by the luminaires to better fit to their utilization. A luminaire illuminating a zebra crossing will not have the same light distribution as a luminaire illuminating a highway. Depending on these characteristics, lighting apparatuses will be chosen and adjusted to obtain a desired lighting pattern on the surface to be illuminated.

The base support to which the lighting apparatus will be attached is often already existing. For example, poles along existing highways have been placed sometimes decades ago and reused by merely changing the luminaire head. However, these base supports are not always oriented in the same way. Some pole ends may be oriented horizontally and others at a slight angle. In order to make sure that the lighting pattern to be illuminated on the surface is as desired, it is sometimes necessary to be able to adapt the orientation of the luminaire head in function of the base support, the desired application, etc.

WO2019229045A1 in the name of the applicant discloses an angle adjustment system which allows for a luminaire head to be adjusted with ease to a variety of different orientations while still allowing for a high degree of precision, and which is not unnecessarily complex. Another existing system for tilting a luminaire head is described in international patent application WO2020144191 in the name of the applicant.

Although both systems provide a good and robust solution for adjustably attaching a luminaire head to a support such as a pole, for some applications it is advantageous to look for alternative systems, and in particular systems that can be easily built with standard components.

SUMMARY

According to a first aspect of the invention, there is provided a tiltable connector for a luminaire, configured to be attached between a luminaire head and a base support. The tiltable connector comprises a hollow body, such as a tube-like hollow body, having an axis. The hollow body comprises a plurality of pairs of first holes configured to receive a first fixation means. Each one of the plurality of pairs of first holes is aligned along a tilt axis oriented at a predetermined angle with respect to the axis. The predetermined angle is different for each one of the plurality of pairs of first holes. The tiltable connector is such that the luminaire head can be fixed at a first tilt angle by introducing the first fixation means in a first selected pair of first holes from the plurality of pairs of first holes and at a second different tilt angle by introducing the first fixation means in a second selected pair of first holes from the plurality of pair of first holes. Preferably, the laminaire is an outdoor luminaire.

In other words, the tiltable connector serves as an attaching link between the luminaire and the base support. The tiltable connector has a hollow body, which comprises a plurality of pairs of holes that are aligned at predetermined angles. For example, the tiltable connector is a tube with holes distributed along the periphery. By inserting the first fixation means in a first selected pair of first holes of the tiltable connector, e.g. the first fixation means may be a pair of screws that are inserted through a pair of fixation holes of the luminaire head and in a first selected pair of first holes of the tiltable connector, the luminaire head can be attached to the connector, and thus effectively to the base support, when the connector is attached to the base support, such that the luminaire head is fixed at a first tilt angle corresponding to the predetermined angle that corresponds to this first selected pair of first holes. Similarly, by inserting the first fixation means in a second selected pair of first holes, the luminaire head can be attached to the connector such that the luminaire head is fixed at a second tilt angle corresponding to the predetermined angle that corresponds to this second selected pair of first holes The tiltable connector therefore provides a simple way to choose the tilt angle at which the luminaire head is attached relative to the base support.

In this way, a luminaire head may be installed on a base support at a desired orientation without the need to change or modify the pre-existing attaching means of the luminaire head.

In this way, it is also avoided that base supports that may be slightly tilted, for example because they have not been correctly installed. e.g. not exactly vertical or horizontal, or that are tilted due to wear, should be replaced or adjusted. Any luminaire head, compatible with the above-mentioned connector, may still be installed on these tilted base supports by compensating the undesired tilt of the base support.

In addition, the hollow body allows cables originating from the base support to pass through the hollow body to be connected to the luminaire head and to be protected from the external environment by the connector.

According to a preferred embodiment, each first hole of a first pair is at a distance of each first hole of a second pair. In other words, the first holes of one first pair are distinct from the first holes of a second pair. In this way, choosing a predetermined angle among the predetermined angles of the at least first and second pairs is more easily achieved, since there is less risk of confusion between the holes. In another embodiment, a first hole of a first pair could be the same as a first hole of a second pair, and the other first holes of the first and second pair could be distinct. This allows to reduce the number of holes in the connector.

According to a preferred embodiment, each first hole extends from an external surface of the hollow body to an internal surface thereof. In other words, the holes are traversing holes. In this way, screws may be used as the first fixation means to be accommodated in the holes.

According to a preferred embodiment, the plurality of pairs of first holes is positioned such that a rotation of the hollow body around the axis allows to select a pair of the plurality of pairs of first holes. According to an even more preferred embodiment, the pairs of first holes are distributed along a circumferential surface of the hollow body.

In this way, choosing between a first predetermined angle. corresponding to a first pair of first holes, and a second predetermined angle, corresponding to a second pair of first holes, is simply achieved by rotating the hollow body such as to insert the fixation means in the desired pair of first holes, corresponding to the desired predetermined angle.

According to a preferred embodiment, the plurality of first holes comprises a first pair of first holes located in a first quadrant of the hollow body, and a second pair of first holes located in a second quadrant of the hollow body. It is noted that it is also possible to provide multiple pairs in a first quadrant and multiple pairs in a second quadrant.

In this way, choosing a predetermined angle among the predetermined angles of the at least first and second pairs is more easily achieved, since the first and second pair of first holes corresponding to different angles are separated. There is therefore less risk of confusion between the pairs of first holes corresponding to different angles and it is easier to choose the desired pair.

According to a preferred embodiment, the hollow body has an external surface, said external surface comprising a plurality of substantially flat facets. The plurality of pairs of first holes comprises a first pair of first holes located in a first facet and a second pair of first holes located in a second facet. It is noted that it is also possible to have multiple pairs of first holes in a first facet and multiple pairs of first holes in a second facet. Also, some facets may be without holes.

According to a preferred embodiment, the tiltable connector further comprises a plurality of pairs of second holes configured to receive a second fixation means. Each pair of second holes corresponds to a pair of first holes and each of the second holes is opposite a corresponding first hole of the plurality of pairs of first holes with respect to a plane comprising the axis.

In this way, the connector may be coupled, to the luminaire head or base support with two fixation means, one on a first side of the connector and a second one on a second side opposite thereof.

Since the luminaire head or base support is thus fixed at two opposite sides of the connector, the stability and/or the vibrating properties of the installed luminaire are improved.

According to a preferred embodiment, where the connector has an external surface with multiple facets, the plurality of pairs of second holes comprises a first pair of second holes arranged in a first facet and a second pair of second holes arranged in a second facet different from the first facet. In this way, as mentioned above, there is less risk of confusion between the pairs of second holes corresponding to different angles and it is easier to choose the desired pair of second holes.

According to a preferred embodiment, the plurality of pairs of first holes comprises a first pair comprising a pivot hole and a first angle hole and a second pair comprising the pivot hole and a second angle hole. In other words, the pivot hole is common to the first and second pair of first holes.

In this way, when coupling the connector to either the luminaire head or the base support, the pivot hole may be used to secure the connector while not having yet chosen the angle hole, and therefore the desired tilt angle at which the coupling is desired. In this manner, different tilt positions may be tested without having to completely uncouple and recouple the connector each time. 5

According to a preferred embodiment, the hollow body comprises a tilt portion comprising the plurality of first holes and an attachment portion comprising at least one attaching hole. Preferably, the attachment portion comprises two attaching holes at a distance of each other in the direction of the axis.

In this way, the hollow body comprises a tilt portion with the purpose of choosing the desired tilt angle for the luminaire head as well as coupling the connector to either one of the luminaire head or the base support and an attaching hole with the purpose of attaching the connector to the other one of the luminaire head or the base support.

In the following, embodiments of the connector will be described where the first holes are used to couple the connector to the luminaire head, with the help of the first fixation means, while the connector is coupled to the base support by separate attachment means. However, the skilled person will understand that embodiments of the connector with an opposite way of achieving the coupling are also possible, namely wherein the connector is coupled to the base support through the use of the first holes, while the coupling of the connector to the luminaire head is achieved through separate attachment means. For the sake of conciseness however, only the former embodiments will be discussed but the skilled person will understand that technical advantages obtained for the former embodiments may also be obtained for the latter.

Additionally, by having two attaching holes that are at a distance of each other in the direction of the axis, e.g. that may be separated by a predetermined distance and aligned to the axis of the hollow body, the coupling of the connector to the base support is more stable and less prone to vibrations.

According to a preferred embodiment, the first fixation means comprises a first pair of bolts or screws. Preferably, a first bolt or screw of the first pair of bolts or screws passes through both a first hole of a first pair of first holes and a second hole corresponding to the first hole and preferably, a second bolt or screw of the first pair of bolts or screws passes through both the other first hole of the first pair of first holes and another second hole corresponding to the other first hole.

In this way, the same bolt or screw may pass both through a first and second hole, reducing the number of bolts or screws to be used and providing additional stability.

According to a preferred embodiment, the second fixation means comprises a second pair of bolts or screws, different from the first pair of bolts or screws.

According to a preferred embodiment, the first holes and/or the second holes are threaded holes. In this way, better stability and vibration properties may be obtained for the assembled luminaire.

According to a preferred embodiment, the tiltable connector comprises markings. The markings indicate either one or both of: at least one of the plurality of predetermined angles, at least one pair of first holes corresponding to the at least one of the plurality of predetermined angles. Preferably, the markings are engravings.

For example, the markings may be in the form of a pair of values of a predetermined angle situated next to the pair of first holes corresponding to that value. In another example the markings may be in the form of a value of a predetermined angle from which a pair of arrows depart to arrive at the pair of first holes corresponding to that value. In yet another example where the tiltable connector comprises facets, the marking may be in the form of a value of the predetermined angle marked on the facet corresponding to that predetermined angle.

In this way, choosing a predetermined angle among the predetermined angles of the at least first and second pairs is more easily achieved, since the angles are marked and therefore more easily distinguishable. There is therefore less risk of confusion between the pairs of first holes corresponding to different angles and it is easier to choose the desired pair. This may be advantageous at the installation of the luminaire head, but also when performing maintenance on the luminaire head. For example, when the markings show a predetermined angle and the first holes corresponding to that angle, a maintenance operator may easily recognize at what angle the luminaire head is installed. If the luminaire head needs to be removed temporarily or replaced. the operator may more easily know at what angle it was previously installed.

According to a second aspect of the invention, there is provided a luminaire head comprising a housing with an open end portion wherein the tiltable connector according to any one of the embodiments of the first aspect disclosed hereinbefore is inserted in the open end portion.

Conversely, there is also provided a luminaire head comprising a housing with an open end portion wherein the tiltable connector according to any one of the embodiments of the first aspect disclosed hereinbefore, is inserted in or over or around the open end portion.

The skilled person will understand that the advantages that have been discussed above for the first aspect of the invention are still valid for this second aspect and will not be discussed again.

According to a preferred embodiment, the open end portion comprises at least one pair of first fixation holes configured to cooperate with a pair of the plurality of pairs of first holes of the tiltable connector using the first fixation means.

According to a preferred embodiment, the tiltable connector comprises a hollow body comprising a tilt portion comprising the plurality of first holes and an attachment portion comprising at least one attaching hole, preferably two attaching holes at a distance of each other in the direction of the axis and is inserted with the tilt portion thereof in the open end portion, whilst the attachment portion protrudes out of the open end portion.

According to a preferred embodiment, the luminaire head and/or the tiltable connector comprises markings. Preferably, the markings comprise information on any one of or any combination thereof: at least one of the at least one pair of first fixation holes, at least one of the plurality of predetermined angles of the tiltable connector, at least one of the plurality of pairs of first holes of the tiltable connector corresponding to the at least one of the plurality of predetermined angles.

Preferably, the markings are engravings.

According to a third aspect of the invention, there is provided a luminaire. The luminaire comprises a base support having a pole end, the luminaire head according to any of the embodiments mentioned hereinbefore, wherein the pole end is inserted in the attachment portion of the hollow body.

The skilled person will understand that the advantages that have been discussed above for the first and second aspects of the invention are still valid for this third aspect and will not be discussed again.

By outdoor luminaire, it is meant laminaires which are installed 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 area such as roads and residential areas in the public domain, private parking areas and access roads to private building infrastructures, etc.

The base support may be preferably a pole. For example, the base support may be a pole suited for use as post-top or side-entry assembly. However, base supports are not limited to poles and may be any type of support such as supports configured to be secured to a ground surface or to a wall, such as a vertical wall or a ceiling.

Several types of luminaire heads, in metal or in plastic, such as the ones of the Dutch patent applications NL2033601, NL2033710, NL2031305, NL2032515 as well as the international patent applications WO2022129193A1, WO2021180706A1, WO2019197489A1, WO2019015976A1 all in the name of the applicant may be provided with such a connector part and may benefit from the advantages of the first aspect of the invention.

DESCRIPTION OF THE EMBODIMENTS

Fig. 1 illustrates a tubular tiltable connector 100. The tiltable connector 100 is configured to be inserted between a luminaire head and a base support and comprises a hollow body having an axis

A. In this case, the hollow body is tubular. The hollow body comprises a plurality of pairs 111, 112, 113 of first holes 111A, 111B, 112A, 112B, 113A, 113B configured to receive a first fixation means. Each one of the plurality of pairs 111, 112, 113 of first holes is aligned along a tilt axis BI,

B2, B3 oriented at a predetermined angle 01, 02, 03 with respect to the axis A. The predetermined angle 01, 02, 03 is different for each one of the plurality of pairs 111, 112, 113 of first holes.

Preferably, the connector 100 is used in an outdoor luminaire. As illustrated in Fig. 7, one end 510 of the pole 500 of the outdoor luminaire will then be connected to one end 140 of the connector 100 whilst the other end 110 of the connector 100 is connected to the luminaire head 300.

As illustrated in Fig. 1, each first hole 111A, 111B of a first pair 111 may be at a distance of each first hole 112A, 112B of a second pair 112. In other words, the first holes 111A, 111B of one first pair 111 are distinct from the first holes 112A, 112B of a second pair 112. Each first hole (111A, 111B, 112A, 112B, 113A, 113B extends from an external surface of the hollow body to an internal surface thereof, i.e. the holes are traversing. Although not represented here, the holes may be threaded holes.

The plurality of pairs 111, 112, 113 of first holes 111A, 111B, 112A, 112B, 113A, 113B, which may be distributed along a circumferential surface of the hollow body, is positioned such that a rotation of the hollow body around the axis A allows to select a pair of the plurality of pairs of first holes. In the embodiment illustrated here, the plurality of first holes 111A, 111B, 112A, 112B, 113A, 113B comprises a first pair 111 of first holes 111A, 111B located in a first quadrant 141 of the hollow body, and a second pair 112 of first holes 112A, 112B located in a second quadrant 142 of the hollow body. In an example of use of such tiltable connector 100, if the laminaire head needs to be installed at a tilt angle of 91, the fixation means, e.g. screws or bolts or pins, is inserted in the first pair 111 of first holes 111A, 111B corresponding to that angle 81. If another angle 62 is desired, the connector merely needs to be rotated such that the fixation means may be inserted in the second pair 112 of first holes 112A, 112B corresponding to the target tilt angle 82 instead.

The hollow body may comprise a tilt portion 110 comprising the plurality of first holes and an attachment portion 140 comprising at least one attaching hole 140A, 140B. As illustrated in Fig. 1, the attachment portion 140 may comprise two attaching holes 140A, 140B at a distance of each other in the direction of the axis A.

It should be noted that the tilt portion 110 has the purpose of choosing the desired tilt angle for the luminaire head as well as coupling the connector 100 to either one of the luminaire head or the base support. On the other hand, the at least one attaching hole 140A, 140B has the purpose of attaching the connector 100 to the other one of the luminaire head or the base support.

As illustrated in Fig. 7, an attaching means, e.g. screws or bolts 540A. 540B, may be inserted in the attaching holes 140A, 140B of the attachment portion 140 to attach the tiltable connector to the pole end 510 of the base support 500 and a fixation means, e.g. bolts 401, 402, may be inserted in a pair of first holes of the tilt portion 110 corresponding to a tilting angle 81.

In the following, embodiments of the connector will be described with first holes 111A, 111B, 112A, 112B, 113A, 113B that are used to couple and/or secure the connector 100 to the luminaire head, while the connector 100 is coupled to the base support by other means, e.g. bolts or screws.

However, the skilled person will understand that embodiments of the connector 100 with an opposite way of achieving the coupling are also possible, namely wherein the connector 100 is coupled to the base support through the use of the first holes 111A, 111B, 112A, 112B, 113A, 113B and the fixation means, while the coupling of the connector 100 to the luminaire head is achieved through other means. For the sake of conciseness however, only the former embodiments will be discussed but the skilled person will understand that technical advantages obtained for the former embodiments may also be obtained for the latter.

Typically, a luminaire head such as the ones illustrated in Figs. 5 and 6 is coupled and/or secured to the tiltable connector 100 and the tiltable connector 100 is itself coupled and/or secured to the base support by its attachment portion 140. Typical luminaires comprise a base support having a pole end, which is inserted in the attachment portion 140 of the hollow body of the tiltable connector 100.

In the embodiment of Fig. 2, the hollow body has an external surface comprising a plurality of substantially flat facets 131, 132, 133. The plurality of pairs 111, 112, 113 of first holes 111A, 111B, 112A, 112B, 113A, 113B are comprised in different facets 131, 132, 133.

As illustrated in Fig. 3A and 3B, the tiltable connector 100 may further comprise a plurality of pairs 121, 122 of second holes 121A, 121B, 122A, 122B configured to receive a second fixation means. Each pair 121, 122 of second holes 121A, 121B, 122A, 122B corresponds to a pair 111, 112 of first holes 111A, 111B, 112A, 112B and each of the second holes 121A, 121B, 122A, 122B is opposite the corresponding first holes 111A, 111B, 112A, 112B with respect to a plane comprising the axis A. The plurality of pairs of second holes 121A, 121B, 122A, 122B may also be comprised in different facets, as illustrated in Fig. 3B.

In another embodiment of the tiltable connector 200, illustrated in Fig. 4, the plurality of pairs 211, 212, 213 of first holes 211A, 211B, 212A, 212B, 213A, 213B comprises a first pair 211 comprising a pivot hole 210A and a first angle hole 211B and a second pair 212 comprises the pivot hole 210A and a second angle hole 212B. In other words the tiltable connector 200 may comprise a common pivot hole 210A for different pairs 211, 212, 213 of first holes 211A, 211B, 212A, 212B, 213A, 213B.

Fig. 5 illustrates a luminaire head 300 and a tiltable connector 100, such as the one illustrated in

Fig. 2, and the way in which they are coupled and in which they cooperate to achieve different tilt angles 01, 92, 63, 64, 85.

In the embodiment illustrated in Fig. 5, the luminaire head 300 comprises a housing with an open end portion 350, in which the tiltable connector 100 is inserted. The open end portion 350 comprises at least one pair of first fixation holes (not represented here but situated under the first fixation means 401 and 402) configured to cooperate with the pair of first holes, for example the first pair 111 of first holes 111A, 111B, using the first fixation means 400. To couple the connector 100 and the luminaire head 300, the connector 100 is inserted with the tilt portion 110 thereof in the open end portion 350 of the luminaire head and the fixation means 400 is used to secure the luminaire head 300 to the tiltable connector 100.

It should be noted that although Fig. 5 illustrates a luminaire head 300 comprising a housing with an open end portion 350 in which the tiltable connector 100 is inserted, the skilled person will understand that the tiltable connectors 100 and 200 described herein are not limited to that. Indeed,

the luminaire head 300 may comprise an open end portion which may be inserted in the hollow body of the tiltable connector instead.

The first fixation means 400 illustrated in Fig. 5 comprises a first pair of bolts. A first bolt 401 of the first pair of bolts passes through both a first hole of the first fixation holes of the luminaire head 300 and through one first hole 111A of one pair 111 of first holes and a second bolt 402 of the first pair of bolts passes through both a second hole of the first fixation holes of the luminaire head 300 and the other first hole 111B of the one pair 111 of first holes.

While the first pair 111 of first holes 111A, 111B corresponds to a first tilting angle 61, other tilt angles are possible by choosing other pairs of first holes, for example by choosing a second pair 112 of first holes 112A, 112B corresponding to a different tilting angle 62.

As illustrated in Fig. 5, the luminaire head may be tilted at several predetermined tilting angles that are positive, such as 82, 83, negative, such as 94, 85, or nil, 81 by choosing the corresponding pair of first holes. For a tiltable connector 100 such as the one illustrated in Fig. 2, comprising facets, this choice is done by merely choosing a facet, i.e. a desired tilt angle, by rotating the tiltable connector 100 such that the first holes of the desired facet, i.e. the desired tilt angle, face the fixation holes of the luminaire head 300 and the fixation means 400 may be inserted to couple the luminaire head 300 and the tiltable connector 100 at the desired angle.

As mentioned above in relation to Fig. 3A and 3B, the tiltable connector 100 may further comprise a plurality of pairs of second holes configured to receive a second fixation means, where each pair of second holes corresponds to a pair of first holes and each of the second holes is opposite the corresponding first holes with respect to a plane comprising the axis A. Correspondingly, the open end portion 350 may comprise at least one pair of second fixation holes (not illustrated in Fig. 5) configured to cooperate with the pair of second holes, for example the first pair 121 of second holes 121A, 121B, using the second fixation means.

In some embodiments, the second fixation means may comprise a second pair of bolts different from the first pair of bolts. A first bolt of the second pair of bolts may pass through both a second hole of the second fixation holes of the luminaire head 300 and through one second hole 121A of one pair 121 of second holes and a second bolt of the second pair of bolts may pass through both a second hole of the second fixation holes of the luminaire head 300 and the other second hole 121B of the one pair 121 of second holes.

In other embodiments, the first and second fixation means may be the same, such that the first bolt 401 of the first pair of bolts passes through both a first hole of the first fixation holes of the laminaire head 300 and one first hole 111A of one pair 111 of first holes but also through both one second hole 121A corresponding to the first hole 111A and through a first hole of the second fixation holes of the luminaire head 300. Similarly, the second bolt 402 of the first pair of bolts passes through both a second hole of the first fixation holes of the luminaire head 300 and the other first hole 111B of the one pair 111 of first holes and also through both the other second hole of the second fixation holes of the luminaire head 300 and the other second hole 121B corresponding to the other first hole 111B.

To ease the selection of the pair of holes, the tiltable connector 100 may comprises markings (not illustrated here). The markings indicate either one or both of: at least one of the plurality of predetermined angles 01, 02, 63, 04, 05, at least one pair of marked first holes corresponding to the at least one of the plurality of predetermined angles. Preferably, the markings are engravings. For example, in the case of a tiltable connector 100 with facets, such as the one illustrated in Fig. 2, each facet may be engraved with the value of the predetermined angle corresponding to the first holes of that facet.

The markings may also be comprised on the luminaire head 300 and may comprise information on any combination of: at least one of the at least one pair of first fixation holes, at least one of the plurality of predetermined angles 61, 82, 63, 84, 85 of the tiltable connector 100, at least one of the plurality of pairs of first holes of the tiltable connector 100 corresponding to the at least one of the plurality of predetermined angles 61, 62, 63, 04, 65.

In Fig. 6, two embodiments of a tiltable connector comprising a pivot hole are illustrated while inserted in a luminaire head 300. On the left, a tiltable connector 200 with a pivot hole and comprising a hollow body with rectangular shape section, and on the right a tiltable connector 200 with a pivot hole and comprising a hollow body with circular shape section.

On the left hand side, the tiltable connector is similar to the one illustrated in Fig. 4. such that it will not be described further. However, the open end portion 350 of the housing of the luminaire head 300 comprises several pairs of first fixation holes configured to cooperate with the pairs of the plurality of pairs of first holes of the tiltable connector 200. As also illustrated, the patrs of first fixation holes all comprise a common fixation pivot hole, in which the bolt 402 is inserted. By having several pairs of first holes in the tiltable connector 200 as well as in the open end portion 350 of the luminaire head 300, the effective number of tilting angles that may be achieved is greater, which improves the adaptability of the luminaire head 300 to the base support at which it is installed.

On the right hand side, the tiltable connector is similar to the one illustrated in Fig. 4, although it has a tubular shape instead of a square section, such that it will not be described further. Contrary to the embodiment of the luminaire head 300 illustrated on the left hand side of the figure, the open end portion 350 of the luminaire head 300 is more comparable to the one illustrated in Fig. 5, in that it merely comprises one pair of first fixation holes 400.

Although the embodiments of the tiltable connector 200 illustrated in Fig. 6 comprise pairs of first holes with a common pivot hole instead of pairs of first holes that are distinct from one pair to the other, the technical advantages discussed above are still valid, such that they will not be further discussed here.

It should be noted that above, the coupling of the luminaire head and the tiltable connector with the fixation means has always been illustrated with a fixation means that comprises bolts. However, the skilled person will understand that screws may also be used instead of bolts and that other fixation means are also possible.
