Further it is known to include additional functionalities, either in the modular lamp post itself or in a separate cabinet adjacent a lamp post. Summary

The object of embodiments of the invention is to provide a functional pole module with a functional unit, such as a camera unit, which can be easily integrated in the modular lamp post and which allows the functional unit to be positioned at a certain distance of a vertical axis of the lamp post.

According to an aspect of the invention there is provided a lamp post comprising a support pole and a plurality of pole modules arranged one above the other along a vertical axis of the support pole, and supported by the support pole. The plurality of pole modules comprises a light pole module and a functional pole module. The light pole module comprises a light source. The functional pole module comprises a tubular portion configured for being aligned with the vertical axis of the support pole, a bracket protruding outwardly of said tubular portion, and a functional unit fixed to said bracket. Preferably, the functional unit is a camera unit. Preferably, the bracket is provided with a removable connection interface configured for removably connecting the functional unit to the bracket. In that manner the functional unit can be arranged in a convenient manner at a distance of the vertical axis of the support pole. By having the tubular portion, the functional pole module can be easily coupled to the support pole and/or to another pole module below or above the functional pole module, resulting in a very stable mounting of the functional unit at a distance of the tubular portion. Especially for a camera unit it is advantageous to limit any movement of the camera unit, which is achieved through the use of a functional pole module as defined above.

In an exemplary embodiment the functional unit comprises a connection plate, and the removable connection interface comprises a connection plate fixed to the connection plate of the functional unit. Such a connection plate may be e.g. a horizontally orientated plate or a vertically oriented plate.

According to an exemplary embodiment, the bracket has a length 1 in a length direction protruding outwardly of the tubular portion, and a width w extending in a direction perpendicular to an axial direction A of the tubular portion and perpendicular to the length direction, said width w being preferably inferior to an external diameter D of the tubular portion. The length 1 may be between 15 cm and 100 cm, preferably between 20 cm and 70 cm. The width w may be e.g. between 5 and 25 cm. In a possible embodiment the width w may gradually decrease in a radial direction of the tubular portion. Preferably, the bracket has a height h which may be between 2 and 20 cm, more preferably between 4 and 12 cm, even more preferably between 4 and 10 cm. The height h may vary seen in a radial direction of the tubular portion. In a preferred embodiment, the bracket comprises a compartment configured for housing components, typically electronic components.

In that manner the compartment is suitably sealed, whilst allowing one or more connection lines to be entered from the tubular portion of the lamp post into the compartment and/or from the compartment to the functional unit. In a preferred embodiment, the removable connection interface comprises the passage between the compartment and the functional unit. In an exemplary embodiment, the removable connection interface comprises a first tubular portion configured for receiving a cable gasket and a second tubular portion provided with a screw-thread. In a possible embodiment, the above mentioned cable gasket may comprise a substantially cylindrical sealing body with one or more through-holes for one or more cables, and with one or more cuts extending between the cylindrical outer surface of the substantially cylindrical sealing body and each through-hole, said one or more cuts allowing for a cable to be brought in each through-hole. It is noted that the above mentioned cable gasket may comprise multiple parts for realizing the sealing. For example the substantially cylindrical sealing body may be combined with further sealing bodies to seal the passage to be sealed, e.g. the passage between the compartment and the functional unit or the passage between the compartment and the tubular portion.

In preferred embodiments the functional unit is a camera, e.g. a 360° camera or a pan-tilt-zoom (PTZ) camera. However, in other embodiments the functional unit may be e.g. a display, an antenna, an environmental sensor such as a microphone, or a detector of C0 2 , NO x , smoke, etc., a human interface device (HID), e.g. a loudspeaker, a button. Other examples of a functional unit are a repeater, e.g. a WiFi repeater, a radar sensor, a sign, a publicity banner, a shower head, a sprinkler, a water sprayer, etc. In order to be able to suitably connect any one of those functional units, a plurality of different removable connection interfaces may be provided, e.g. connection interfaces having a different dimension and/or having a different screw-thread and/or having a different coupling mechanism. Depending on the functional unit that needs to be provided, a suitable connection interface can then be selected.

In an exemplary embodiment, the functional pole module is provided with a single bracket.

However, in other exemplary embodiments, the functional pole module may be provided with multiple brackets. For example, the functional pole module may comprise a first bracket with a first functional unit attached to the first bracket, and a second bracket with a second functional unit attached to the second bracket, wherein the first and the second functional unit may be the same or different, and may be any one of the functional units listed above. Those multiple brackets may have any one or more of the features described above for the bracket. The multiple brackets may be connected to the tubular portion at different locations, e.g. a first bracket opposite a second bracket, a first bracket above a second bracket, three or more brackets distributed across the circumference of the tubular portion, etc. By having multiple brackets, the field of operation of the functional units can be increased (e.g. if two brackets with each a camera are provided, the field of view of the cameras is increased), and/or different functional modules can be added

In an exemplary embodiment, the lamp post comprises multiple functional modules provided with one or more brackets. For example, the lamp post may comprises a first functional module with a bracket and a first functional unit attached to the bracket, and a second functional module with a bracket and a second functional unit attached to the bracket, wherein the first and the second functional unit may be the same or different, and may be any one of the functional units listed above.

In an exemplary embodiment, the removable connection interface is a holder of the functional unit, wherein the bracket is provided with a seat for receiving the holder, and wherein the holder is configured for being positioned in different positions in the seat, preferably in a sealed manner. A possible seat and holder have been described in detail in Belgian patent application with application number BE 2018/5412 in the name of the applicant, which is included herein by reference. In BE 2018/5412 the seat is provided generally in a casing, but the skilled person understands that the same seat may be provided in a bracket of any one of the embodiments described above. Other preferred embodiments are disclosed in the dependent claims and the technical advantages of those embodiments are described in the figure description below. The invention further relates to a video surveillance system comprising a plurality of lamp posts as described above, and a remote management subsystem configured to receive raw or processed data from the plurality of lamp posts and/or to send audio and/or video and/or alarm data to said plurality of lamp posts. Also the invention relates to a functional pole module for use in a lamp post as described above. The functional pole module may have any one of the features described above.

According to an exemplary embodiment the plurality of pole modules further comprises an antenna pole module, and the lamp post is further provided with a base station module. The antenna comprises an antenna configured for receiving and emitting cellular data. The base station module comprises a housing and base station circuitry mounted in said housing. The base station circuitry is coupled to the antenna. The base station module may be attached to an external surface of the support pole and may be carried and supported by the support pole. By attaching the base station module to an external surface of the support pole such that the base station module is carried by the support pole, it is not necessary to provide an additional foundation for the base station module contrary to prior art solutions which require an additional cabinet adjacent the support pole.

It is noted that the term "supported" as in "the pole module is supported by the support pole" does not imply that the pole module needs to be directly fixed on the support pole; indeed, there may be intermediate pole modules or elements between the support pole and the pole module; the support pole supports the plurality of pole modules which are arranged one above the other.

According to an exemplary embodiment, the support pole is fixed in the ground and the housing of the base station module is at a distance above the ground. It is noted that the housing may also be in contact with the ground as long as it is carried by the support pole.

According to an exemplary embodiment, the light source comprises a plurality of light emitting diodes, e.g. an array of light emitting diodes, which may be arranged on a PCB. Further, a driver for driving the plurality of light emitting diodes, optionally in combination with a dimmer may be integrated in the lamp post in any known manner. According to an exemplary embodiment the support pole is hollow, and the support pole is provided with a removable door providing access to an inner part of said support pole.

In an exemplary embodiment the lamp post comprises an antenna connection cable from the antenna pole module through an inner part of the support pole; and a power connection cable passing from a lower end of the support pole to the respective pole modules required to be powered.

According to an exemplary embodiment the antenna pole module is arranged in a position above the functional pole module with bracket. Generally, it is desirable to arrange the antenna pole module in a relatively high position. However, usually it is preferred to position the antenna pole module at a lower position than the light pole module. The antenna pole module may be arranged between the functional pole module with bracket and the light pole module, seen in an axial direction of the support pole. In an alternative embodiment the antenna pole module could be arranged below functional pole module with bracket or above the light pole module, e.g. as the highest pole module of the lamp post.

According to an exemplary embodiment the plurality of pole modules are pole modules as disclosed in EP 3 076 073 B l which is included herein by reference. By using pole module connectors as disclosed in EP 3 076 073 B 1 with two connector portions which can be clamped around round end parts of the pole modules, a pole module can be rotated around the axial direction of the support pole in the desired position and then fixed by the connector portions.

Examples of functional circuitry which may be included in a functional pole module or in a housing attached to an external surface of the support pole (in addition to or instead of the base station circuitry), are any one or more of the following:

- power management circuitry comprising e.g. one or more of: a power meter, a fuse, a line protection, a circuit breaker, an electrical connection for multiple power lines, a clock, an astroclock, a power supply module, an PLC, a computer, a communication module, display circuitry, etc. ; preferably the power management circuitry is configured to manage the provision of power to multiple lamp posts, preferably at least three lamp post, e.g. more than ten lamp posts.
