Description

CONNECTOR ASSEMBLY FOR A LUMINAIRE HEAD

FIELD OF INVENTION

The field of the invention relates to a connector assembly for a luminaire head for attaching the luminaire head, to a base support, such as a pole end. to a luminaire head comprising such connector assembly and to a laminaire, typically an outdoor luminaire.

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 luminaire head 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 to update the characteristics of the lighting. 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.

WO2019229045A 1 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,

WO2022069368A 1, both 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 connector assembly for a luminaire head comprising: at least one elongate threaded element and a connector part configured to be arranged around a pole end in a plurality of different tilt positions corresponding with different tilt angles of the luminaire head relative to an axis of the pole end. The connector part is provided with a first set of at least one hole associated with a first tilt position of the plurality of different tilt positions and a second set of at least one hole associated with a second tilt position of the plurality of different tilt positions. The first set of at least one hole is configured such that the at least one elongate threaded element when arranged therein extends at an angle relative to the axis of the pole end which is between 75° and 105° in the first tilt position, preferably between 80° and 100°, more preferably between 85° and 95°, most preferably substantially 90°, and the second set of at least one hole is configured such that the at least one elongate threaded element when arranged therein extend at an angle relative to the axis of the pole end which is between 75° and 105° in the second tilt position, preferably between 80° and 100°, more preferably between 85° and 95°, most preferably substantially 90°.

In other words, the connector part of the connector assembly is configured to be arranged around a pole end, e.g. the connector part may have a hollow part in which the pole end is inserted, and the at least one elongate threaded element, e.g. at least one screw or bolt, is inserted in a first or a second set of at least one hole of the connector part corresponding to a first or a second tilt position corresponding to different tilt angles of the luminaire head.

In this way, a plurality of different tilt angles of the luminaire head relative to the pole end may be achieved in a simple manner, e.g. by merely tightening the at least one threaded element. By using different sets of holes the angle difference between the tilt angle and the threaded element can be compensated. In this way the connection of threaded element and the pole end can always be close to the optimal, substantially perpendicular position.

Tt will be understood that although reference is made here to a luminaire head, embodiments of the invention are also useful for any other edge device, such as a camera or any other sensor, which benefits from the possibility of having different tilt positions.

In a preferred embodiment, at least one of said at least one elongate threaded element has an end portion configured to be in contact with an outer surface of the pole end, the end portion being provided with a recessed part. Preferably, the recessed part is a conical recess.

By having a recessed part, the contact between the at least one elongate threaded element and the outer surface of the pole end is improved. For example, with a conical recessed part, the surface of contact between the at least one elongate threaded element and the outer surface of the pole is substantially arc-shaped, typically substantially ring-shaped. Such surface of contact has improved properties in comparison to the surface obtained with a usual screw/bolt end or with a screw/bolt having a flat end. By having an end portion with a recess, improved vibrational properties are obtained. Also, such end portion works well with soft and hard surfaces. In addition, it allows to exert pressure on a surface even though the surface is not completely perpendicular to the axis of the elongate threaded element, i.e. at first and second angles relative to the axis of the pole end which are not exactly 90°. This allows to have a wider range of tilt positions for the luminaire head.

In a preferred embodiment, the end portion of the elongate threaded element may have a conical outer surface. In this way, an increased pressure may be exerted on the surface of the pole end by the elongate threaded element.

In a preferred embodiment, the connector part is provided with a first wedge shape part intended to be used to arrange the connector part in the first tilt position and a different second wedge shape part intended to be used to arrange the connector part in the second tilt position.

In this way, the tilt position is at least in part determined by the wedge shape part. In this way, the manufacturing of connector parts for different tilt positions is made easier since a same connector part may be used for different types of tilt positions by using the wedge shape part corresponding to the desired tilt position. Also, the wedge shape part may improve the contact between the connector part and the pole end, which also may improve the stability and vibrational properties of the luminaire head. In addition, this may also allow for pole diameter adaptation.

In another embodiment the connector part is provided with a multi-step part intended to be used to arrange the connector part in the first tilt position when the pole end is arranged on a first step thereof or in the second tilt position when the pole end is arranged on a second step thereof. It is noted that the multi-step part may be integrated in the connector part or may be an external part provided to the connector part.

In this way the multi-step part may allow for achieving the different tilt positions, without the need for different wedge shape parts.

In a preferred embodiment, the connector part is a hollow part with a cross section which increases from a first end intended to be connected to the luminaire head, to a second end in which the pole end is to be inserted.

In this way, the pole end is easily inserted in the connector part. Also, by having an increased cross section at the second end compared to the first end, the pole end may be inserted at different tilt angles.

In a preferred embodiment, the holes of the first and second set of at least one hole are threaded holes.

In a preferred embodiment, the first set of at least one hole comprises a first pair of holes and the second set of at least one hole comprises a second pair of holes. In this way, stability and vibrational properties of the luminaire head are improved.

In a preferred embodiment, a hole of the second set of at least one hole is located between the two holes of the first pair. In this way, the connector part is more compact.

In a preferred embodiment with pairs of holes, a distance between the two holes of the first pair and/or a distance between the two holes of the second pair is between 20 mm and 80 mm, preferably between 30 mm and 70 mm, more preferably between 40 mm and 60 mm.

In a preferred embodiment, the first tilt position corresponds with a first tilt angle and the second tilt position corresponds with a second tilt angle, and the difference between the first and second tilt angle is at least 5°, preferably between 5° and 40°, for example between 10° and 40°.

In this way, a wide range of tilt angles, and thus tilt positions is achievable.

In a preferred embodiment, the connector part has an inner surface provided with a pair of protruding ribs extending in a direction substantially parallel to a direction of the axis of the pole end when in the first tilt position of the connector part.

In this way, the contact between the pole end and the connector part is improved, thereby improving the stability and vibrational properties of the luminaire head. In addition, this also provides a better pole diameter adaptation.

In a preferred embodiment, where the connector part comprises the above-mentioned protruding ribs, the first wedge shape part and/or the second wedge shape part comprises a pair of wedge recessed parts corresponding to the connector protruding ribs of the connector part and configured to cooperate therewith. 5

In this way, the use of the wedge shape parts is more simple. For example, the wedge shape parts may simply be placed such that at least part of the protruding ribs of the connector part are introduced in the wedge recessed parts and then slid along the connector protruding ribs. The contact between the connector part and the wedge shape part is improved, thereby improving the stability and vibrational properties of the luminaire head. Also, the combination of the wedge recessed parts and the connector protruding ribs allows for a better position of the wedge shape parts.

In a preferred embodiment, the first wedge shape part comprises a first pair of wedge protruding ribs extending in a direction substantially parallel to a direction of the axis of the pole end when in the first tilt position of the connector part and configured to be in contact with the pole end in the first tilt position. Similarly or alternatively, the second wedge shape part may comprise a second pair of wedge protruding ribs extending in a direction substantially parallel to a direction of the axis of the pole end when in the second tilt position of the connector part and configured to be in contact with the pole end in the second tilt position.

In this way, the contact between the pole end and the wedge shape part is improved, thereby improving the stability and vibrational properties of the luminaire head. In addition, this also provides a better pole diameter adaptation.

Although the advantages of the second aspect specific to the connector part will not be explicitly discussed. the skilled person will understand that the advantages of the first aspect also apply to the second aspect.

In a preferred embodiment, the luminaire head comprises a casing, wherein the connector part is an integral part of the casing or is fixed to the casing, and wherein a light source is arranged in the casing.

By having a connector part that is separated from the casing of the luminaire head, different tilt positions than the tilt positions of the connector part may be achieved by merely changing the connector part. In this way, the luminaire head does not need to be changed, which allows for a more cost and time efficient maintenance.

DETAILED DESCRIPTION OF THE FIGURES

Figs. 1A and 1C are perspective views of an embodiment of a connector assembly according to the first aspect of the invention in a tilt position, e.g. a default tilt position. In this embodiment, the connector assembly comprises a pair of elongate threaded elements 10 and a connector part 20 configured to be arranged around a pole end 200. The connector part 20 is a hollow part configured to receive a pole end 200, typically a pole end 200 of a pole of an outdoor luminaire. The connector part 20 is in one tilt position, e.g. the default tilt position, among the plurality of tilt positions in which it is configured to be arranged. The default tilt position illustrated here corresponds to a tilt angle a of the luminaire head 100, that is essentially in this case, relative to an axis A of the pole end 200. The connector part 20 is provided with a set of at least one hole, here a first pair of holes 21, associated with this tilt position of the plurality of different tilt positions and a second set of at least one hole, here a second pair of holes 22, associated with another tilt position of the plurality of different tilt positions.

The pair of threaded elements 10 is for example a pair of screws or bolts. Correspondingly, the holes of the two sets of at least one hole, i.e. the first pair 21 and the second pair 22 of holes, may be threaded holes. The threaded elements 10 are inserted in one of the pairs of holes, e.g. the first pair 21 of holes, to exert a pressure on an outer surface of the pole end 200 and secure the pole end 200 in the connector part 20 at a given tilt position. As illustrated in Fig. 1B, at least one of the elongate threaded elements 10 has an end portion 11 configured to be in contact with an outer surface of the pole end 200, the end portion 11 being provided with a recessed part 12. Preferably, as illustrated, the recessed part 12 is a conical recess. The end portion 11 of the elongate threaded element 10 may additionally have a conical outer surface 13.

The connector part 20 may also comprise a pair of protruding ribs 28 that extend in a direction substantially parallel to a direction of the axis A of the pole end 200 when in a default tilt position of the connector part 20. As illustrated in Figs. 1A and 1C, the default tilt position may for example correspond to a tilt angle a of the luminaire head 100, that is essentially 0 here, relative to an axis A of the pole end 200. Other tilt positions are of course possible. As visible in Fig. 1C, which illustrates a perspective view of the connector assembly in the tilt position of Fig. 1A as seen from a direction aligned with the axis A of the pole end 200, the pair of protruding ribs 28 is configured to contact the pole end 200 when the elongate threaded elements exerts pressure on the pole end 200 such as to secure the connector part 20 to the pole end 200.

The connector assembly also comprises an opening 300, configured to provide a passage, e.g. for the power supply cables, to the luminaire head 100. As illustrated the connector part 20 may have a closed end wherein it is connected to the luminaire head 100. wherein the opening is provided in the closed end. Optionally, a cable gland (not shown) may be provided in the opening 300.

Figs. 2A and 2B illustrate cross section views (in a longitudinal direction) of a connector assembly similar to the one of Figs. 1A-1C in a first and second tilt position, respectively.

As illustrated on Fig. 2A, a first pair of holes 21 is configured such that the pair of elongate threaded elements 10, when arranged therein, extend at an angle B1 relative to the axis A of the pole end 200 which is between 75° and 105° in the first tilt position. Preferably this angle B1 is between 85° and 95°, more preferably substantially 90°. Similarly, as illustrated on Fig. 2B, the second pair of holes 22 is configured such that the pair of elongate threaded elements 10, when arranged therein extend at an angle P2 relative to the axis A of the pole end 200 which is between 75° and 105° in the second tilt position. Preferably, this angle is between 85° and 95°, more preferably substantially 90°.

The first tilt position, illustrated in Fig. 2A, corresponds with a first tilt angle al and the second tilt position, illustrated in Fig. 2B, corresponds with a second tilt angle «2. In the first tilt position, the connector part 20 is provided with a first wedge shape part 30 intended to be used to arrange the connector part 20 in the first tilt position. It should be noted that although the first pair of holes 21 may be the same as the one illustrated in Fig. 1A, the first tilt angle al of the luminaire head 100 illustrated here may be different to the tilt angle a corresponding to the tilt position of Fig. 1A. The angle al is indeed different to the one of Fig. 1A, which was substantially 0. In the second tilt position, the connector part 20 is provided with a second wedge shape part 40 intended to be used to arrange the connector part in the second tilt position. The difference between the first tilt angle al and the second tilt angle a2 may preferably be at least 3°, more preferably between 5° and 40°, for example between 10° and 40°.

The connector part 20 may comprise a wedge fixation hole 24. The wedge shape parts 30 and 40 also comprise a fixation hole 34, 44, configured to correspond to the wedge fixation hole 24 of the connector part 20. The fixation holes 24, 34, 44 are configured to secure the wedge shape parts 30 and 40 in the hollow part of the connector part 20. For example, the fixation hole 34, 44 of the wedge shape parts 30, 40 may be a threaded hole.

The connector part 20 illustrated in Figs. 2A-2B is a hollow part with a cross section which increases from a first end 25 intended to be connected to the luminaire head 100, to a second end 26 in which the pole end 200 is to be inserted.

As illustrated on Figs. 2A-2B, a hole of the second pair of at least one hole 22 is located between the two holes of the first pair of holes 21. Although not visible on the figures, a distance between the two holes of the first pair 21 and a distance between the two holes of the second pair 22 is preferably between 20 mm and 80 mm, preferably between 30 mm and 70 mm, more preferably between 40 mm and 60 mm.

Figs. 3A and 3B illustrate a perspective view of the connector assembly of Fig. 2B. In Fig. 3A, the second wedge shape part 40 is illustrated, while it has been removed in Fig. 3B. As visible on Fig. 3A, the wedge shape part 40 may comprise wedge protruding parts 41, extending in a direction substantially the same as the direction of the axis A of the pole end 200 in the desired tilt position and configured to contact the upper outer surface of the pole end 200.

The wedge shape part 40 may comprise wedge recessed parts 42, corresponding to the connector protruding parts 28 of the connector part 20 and configured to cooperate therewith, for example, to allow for the wedge shape part 40 to be slid along the connector protruding parts 28.

Fig. 4 is a top side view of a luminaire head 100 comprising a connector part 20 arranged around the pole end 200. As illustrated, the luminaire head 100 may comprise a casing 500 and the connector part 20 may be an integral part of the casing 500, in which a light source (not represented here) may be arranged.

A power supply line 600, or any line, may extend from the pole through the connector assembly into the luminaire head 100, for example through the opening 300 illustrated in Figs. 1C and 3B.

Figs. 5A and 5B are perspective views of alternative embodiments of a connector part. It is noted that a wedge shape part may be connected or integrated to the connector part 20 in any possible way. Here the wedge shape part is a multi-step part.

As illustrated in Fig. SA and 5B, a wedge shape part may also have steps, configured to secure the pole end 200 at different tilt positions.

Reference is first made to Fig. 5B, where a first tilt position corresponds with the first step comprising the first surface 111a, T1 and where a second tilt position corresponds with the second step comprising the second surface 1124, T2. In order to arrange the luminaire head 100 in a first tilt position, the pole end 200 may be introduced such that contact is made between the outer surface of the pole end 200 and the first surface 111a, T1 and then securing the pole end 200 in place with the elongate threaded elements 10. For increased stability, that the pole end 200 may be made to abut the surface T12, joining the first 111a, T1 and second 112a, T2 surfaces. In order to arrange the luminaire head 100 in the second tilt position, the pole end 200 may simply be secured while contact is made between the outer surface of the pole end 200 and the second surface 112a,

T2 instead of the first 111a, T1.

Fig. 5A illustrates another embodiment, where the central portion of the steps comprises a recess and wherein the first and second surfaces each comprise a first and second slanted surface. For example, the first surface corresponding to the first tilt position comprises a first slanted first surface Tla and a second slanted first surface T1b, configured to contact the pole end 200 when it is arranged in the first tilt position. The angle ò between these slanted first surfaces may correspond with the diameter of the pole end 200.

When a wedge shape part as illustrated in Fig. SA and SB is used. different tilt positions are possible with a single wedge shaped part. It is noted that such wedge shape part may also be an integral part of the connector part 20.

Figs. 6A and 6B illustrate cross section views in the longitudinal direction of an embodiment of a connector assembly 20 when arranged around a pole end 200 with an integrated wedge shape part 30 with multiple steps. in this case two steps. In a transversal view, the multi step wedge shape part 30 may be similar to the connector protruding parts 28 such as the ones of the connector part 20 of

Figs. 1A, IC, 3A, 3B. It differs however in that the multi step wedge shape part comprises multiple steps that allow multiple tilt positions, similarly to the embodiments of Figs. SA and 5B.

Whilst the principles of the invention have been set out above in connection with specific embodiments, it is to be understood that this description is merely made by way of example and not as a limitation of the scope of protection which is determined by the appended claims.
