The field of the invention relates to lamp posts, in particular lamp posts in the form of outdoor luminaires Particular embodiments relate to the field of modular lamp posts with a tubular pole, comprising one or more functional modules aligned with the tubular pole.
EP 3 076 073 B1 in the name of the applicant discloses a modular lamp post which is readily assembled and installed in the field whilst providing rigidity, structural integrity and sealing. The lamp post comprises a plurality of modules mounted on a support pole. The modules are connected to one another by respective module connectors and one module thereof is connected to the support pole by a module connector. EP 3 076 073 B1 is included herein by reference.
The object of embodiments of the invention is to provide an improved lamp post allowing integrating additional functionalities in the lamp post, and in particular allowing integrating an antenna component in a lamp post in an improved manner.
According to a first aspect of the invention there is provided a lamp post. The lamp post comprises a tubular pole and a modular support structure arranged in the tubular pole. The tubular pole is made out of a non-metallic material. The modular support structure comprises at least one carrier module for carrying at least one component, wherein the carrier module comprises a top interface, a bottom interface and an elongated structure between the top and bottom interface.
Embodiments are based inter alia on the inventive insight that by providing a tubular pole made out of a non-metallic material, various components may be arranged in the tubular pole, such as an antenna component, without being hindered by the material of the tubular pole. Further, by providing a modular support structure with one or more carrier modules in the tubular pole, components can be arranged in the pole in a convenient manner by inserting the modular support structure in the tubular pole. Further, the available space in a pole is used in a useful manner, resulting in a compact lamp post.
Preferably, the at least one carrier module comprises a first carrier module and a second carrier module for carrying a first and a second component, respectively. The first carrier module is arranged above or below the second carrier module. The first and second carrier module each comprise a first interface, a second interface and an elongated structure between the first and second interface. The second interface of the first carrier module is connected to the first interface of the second carrier module. The first interface may be a top or a bottom interface, and accordingly the second interface may be a bottom or a top interface.
Preferably, the first carrier module is formed as a first rigid frame and the second carrier module is formed as a second rigid frame which is distinct from the first rigid frame. In that manner a truly modular support structure is obtained, wherein a carrier module can be removed or added without having to disassemble another carrier module. Or, stated differently, the first and the second carrier module do not share a common structural member.
In preferred embodiment, the lamp post is an outdoor luminaire By outdoor luminaires, it is meant luminaires 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 at least one component may comprise an antenna component. More in particular, the first component and/or the second component may be an antenna component, preferably an antenna component configured for receiving and emitting cellular data. In an exemplary embodiment, the or each antenna component is a substantially cylindrical component comprising a plurality of cylinder segments, each segment being associated with an antenna element. In that manner a large angular range can be covered by the antenna component.
In addition or alternatively, the at least one component may comprise any one of the following: a wireless communication device, a sensor device, such as an RF sensor or a light sensor.
Also further components may be arranged in the tubular pole which are not necessarily supported by the modular support structure, such as a light source, driver circuitry for driving a light source, base station circuitry, power management circuitry, telecommunication circuitry, audio system management circuitry, WiFi circuitry, charger circuitry, an environmental sensor and the associated circuitry, any other type of sensor such as radar sensor, sound sensor, vibration sensor and the associated circuitry, a socket such as an electrical socket, a repeater circuitry, a sign such as a publicity banner, a water discharge device, a trash bin, a human interface device (HID) and the associated circuitry, such as a camera, a loudspeaker, a button, a display, a signaling device, a plug-in device.

The fibers may be provided in the form of a fabric, e.g. a unidirectional fabric laminate. The tensile strength of the fabric laminate is preferably between 600 and 1000 MPa according to ASTM D3039, and the tensile modulus is preferably between 20 and 60 GPa according to ASTM D3039. The plastic may comprise any suitable polymer, e.g. a thermoset polymer matrix. Instead of glass fibers also other fibers may be used.
Preferably, the tubular pole is cylindrical. However, other shapes such as a prism shape are also possible.
In an exemplary embodiment, a spacer is arranged between the first and the second carrier module. In that manner the first and second component may be arranged at a suitable distance of each other in the tubular pole. Also, the use of a spacer may make it possible to position the second carrier module more easily in different positions with respect to the first carrier module. Preferably, the spacer comprises an upper connection interface, a lower connection interface, and an elongated structure such as a plurality of elongate rods extending between the upper connection interface and the lower connection interface. In other embodiments a tubular section may be used as the elongated structure. The upper and/or the lower connection interface and the corresponding bottom and/or top interface of the carrier module which is connected thereto may be configured such that the second carrier module is positionable in different positions with respect to the first carrier module. To move from a first to a second position of the plurality of positions, the second carrier module may be rotated around an axis which corresponds with the axis of the tubular pole.
According to an exemplary embodiment, the elongated structure of a carrier module comprises a plurality of bars extending between the top interface and the bottom interface. By using bars a light-weight rigid carrier module can be obtained. Optionally, the bars have a substantially U-shaped cross section, preferably with the legs of the U-shape pointing in a substantially radial direction of the tubular pole. The U-shape allows connection lines such as cables to be passed in the channels created by the U-shaped bars. However, in other embodiments the bars may have a different shape. For example, the bars may be tubular members through which one or more cables may extend.
Preferably, the plurality of bars is distributed along a periphery of the carrier module. For example, the plurality of bars may comprise at least three bars equally distributed along the periphery. In that manner, a mechanically robust carrier module is obtained. In that manner the component can be located in an area surrounded by the plurality of bars.
In another exemplary embodiment, instead of or in addition to the plurality of peripheral bars, there may be provided a central rod extending between the top interface and the bottom interface, and the component may be located around the central rod.
According to an exemplary embodiment, the top interface comprises at least one round, preferably ring-shaped, flange and/or the bottom interface comprises at least one round, preferably ring-shaped, flange. In that manner a light-weight rigid carrier module can be obtained. The ring-shaped flanges may be used for connection purposes, but one or more ring-shaped flange may also be used to stabilize at least one component. More in particular, one or more ring-shaped flanges may surround an outer circumference of the component. In that manner, the vibration of the components can be limited.

By having multiple bolt pairs, the two hooks can be coupled to different bolt pairs and hence the supports structure can be attached in a plurality of different positions to the metal insert. In that manner, the component can be given a suitable orientation.
It is noted that also the connection interfaces between the first and second carrier module, and/or between the first or second carrier module and the spacer, may be such that the first carrier module can be positioned in different positions with respect to the second carrier module. This is especially advantageous when the first and second components are a first and second antenna components arranged one above the other on the first and second carrier module. In such a configuration, it is generally desirable to orient the second antenna differently compared to the first antenna such that a direction which is not well captured by the first antenna is captured by the second antenna.
Preferably, the connection structure further comprises an internal module connected to the metal insert and arranged at least partially in the metal insert, said internal module having a connection interface.

According to an exemplary embodiment, the top and/or bottom interface is provided with one or more anti-vibration elements extending from an outer circumference of the top and/or bottom interface in the direction of the tubular pole. In that manner the first and second component can be supported in a robust manner, wherein the vibrational load on the modular support structure is limited. Optionally, the one or more anti-vibration elements comprise a plurality of wings protruding outwardly from the top and/or bottom interface. The anti-vibration elements may be made out of a polymer material.
Preferably, the elongated structure and/or the top and/or bottom interface of a carrier module is made out of metal. However, in other embodiments, the carrier module could also be made out of a rigid plastic material.

According to an exemplary embodiment the non-metallic material of the tubular pole may comprise a translucent or transparent material. The tubular pole may be fully transparent or translucent, or may have a transparent or translucent portion. Optionally, a light source may be arranged in the tubular pole. The light source may be arranged on a carrier module of the modular support structure but may also be arranged on a different support structure. For example, a PCB with a plurality of light sources arranged thereon may be arranged in the tubular pole, wherein the PCB may be oriented upwardly, e.g. vertically, in the tubular pole.
The tubular pole may be made out of one piece, but could also be made out of a plurality of pieces.

The connection structure 700 comprises a metal insert 710 arranged in an end portion of the tubular pole 100. The metal insert 710 may be fixed to the pole 100 using screws or bolts 713. In another embodiment the metal insert may be glued in the pole 100. The metal insert 710 may be substantially cylindrical such that it fits well in the hollow pole 100. The carrier module 200 is connected to the metal insert 710 using attachment means. Possible attachment means will be discussed below with reference to
The tubular pole 100 is provided with at least one removable door 110 providing access to an inner part of the tubular pole 100. In the illustrated embodiment, only one door is shown, and this door will provide access to the bottom interface 220 of the shown carrier module 200, and to the top interface of an optional further carrier module (not shown) which may be present below.

To move from a first to a second position of the plurality of positions, the second carrier module 200′ may be rotated around an axis which corresponds with the axis of the tubular pole. More in particular, as shown in

In embodiments of the invention, the first and second component may be a substantially cylindrical antenna component comprising a plurality of cylinder segments, wherein each segment is associated with an antenna element, such that substantially 360° is covered. However, the antenna component 400, 400′ may also be a directional antenna with a limited angular range, e.g. a range covering between 90° and 180°. When using multiple such antenna components 400, 400′ arranged one above the other, and rotated with respect to each other, it is then still possible to cover substantially 360°. It is noted that also when a substantially cylindrical antenna component comprising a plurality of cylinder segments is used, there exist areas between the segments which will have a limited reception. If the orientation of the second antenna component is different with respect to the first antenna component (e.g. rotated over an angle which is different from 360° divided by the number of segments), such directions of low reception can be avoided.
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.
