A lighting system 10 is shown in Figure 1.

In terms of air traffic, rail, ship, bus or walking, tagging means all trademarks or fixed buoys in place to signal danger or indicate the route to follow using all means, particularly light means.

The markup term and refers to a way to signal the presence of information through a diffuse light source integrated, to improve the contrast of the display information and thereby ensure good readability even in a place dark or poorly illuminated.

The lighting system 10 is therefore proper to indicate a specific location, the location corresponding to a hazard or access particular information.

The lighting system 10 comprises a mast 12 and a marking device 14 installed on the mast 12.

The mast 12 is a cylinder.

By definition, a cylinder is a solid bounded by a cylindrical surface and by two strictly parallel planes. The cylindrical surface is a surface in the space defined by a straight, called generator via a variable point describing a plane closed curve, called the director curve and keeping a fixed direction. The surface delimited by the arch axis is called the base of the cylinder in the following.

According to the example of Figure 1, the generatrix extends along a axial direction of said direction. In Figure 1, the axial direction is indicated by an axis Z.

In addition, the shape of the tower base 12 is arbitrary.

In the case of Figure 1, the shape of the tower base 12 is a disc.

The diameter of the tower base 12 is, for example, between 70 mm (millimeters) and 300 mm.

Alternatively, the shape of the tower base 12 is oval.

According to yet another variant, the shape of the tower base 12 is a rectangle, a square, a triangle or a polygon having more than four sides. A pentagon or hexagon are examples of polygons with more than four sides.

Alternatively, the mast 12 is conical.

By definition, a cone is a solid bounded by a plane and by a straight line, called generator, passing through a fixed point called top and a variable point describing a curve called directrix curve, the plane not containing the vertex and being secant to all generators.

According to the example of Figure 1, the mast 12 is hollow, that is to say the mast 12 has the shape of a tube defining an empty interior space.

The marking device 14 is adapted to illuminate the environment, the mast 12 for supporting the marking device 14.

According to a particular example, the marking device 14 is capable of emitting light information.

Alternatively, the marking device 14 is intended to highlight visual information, for example to indicate a road.

According to one embodiment, the marking device 14 is intended to highlight particular information.

Alternatively, the marking device 14 is intended to warn of the presence of danger.

The marking device 14 comprises a unit for generating electrical energy

16 and a unit for producing light energy 18. For simplicity, hereinafter, the unit of electrical energy production is simply denoted electrical unit 16 while the production unit of light energy 18 is denoted light unit 18.

The electrical unit 16 is capable of generating electrical energy to power the light unit 18.

The power unit 16 comprises a photovoltaic module 20 and a support 22 holding the photovoltaic module 20 on the mast 12.

By definition, a photovoltaic module is a photovoltaic solar cell or photovoltaic solar panel. In addition, a photovoltaic module is an electrical generator of direct current having a set of photovoltaic cells electrically connected, the module for providing electric power from solar energy.

According to the example of Figure 1, the photovoltaic module 20 is a photovoltaic module of organic type. This means that the photovoltaic module includes special photovoltaic cells, including at least the active layer is made of organic molecules. Therefore, the photovoltaic effect is, for a photovoltaic cell obtained with the semiconductor material properties.

A semiconductor is considered since the organic semiconductor comprises at least one link in the group consisting of covalent bonds between a carbon atom and a hydrogen atom, links

covalent between a carbon atom and a nitrogen atom, or of bonds between a carbon atom and an oxygen atom.

An organic photovoltaic module is an assembly comprising at least two adjacent photovoltaic individualized cells from each other and connected in series or in parallel. Forming an organic photovoltaic module involves depositing superimposed strips of film patterns on a support.

A film is a layer, homogeneous and continuous, made of a material or mixture of materials having a relatively small thickness. It is understood by a relatively small thickness, less than or equal to 500 microns thickness.

For example, the formation of a photovoltaic module involves strips of a width between 9.5 mm and 13.5 mm separated by an interband region of a width of between 0.5 mm and 4.5 mm, the total width of the strip and the interband area being 14 mm. A module consists of depositing several layers by various coating methods or printing.

The use of an organic photovoltaic module can have a relatively small thickness of the power generator, it is understood by a relatively small thickness, a thickness less than or equal to 500 microns, or even less than or equal to 300 microns , resulting in a light weight, ability to customize its cutting size and mechanical flexibility to adapt the instantaneous modulus context of integration.

Alternatively, the photovoltaic module 20 is a flexible module made of amorphous silicon.

According to the example of Figure 1, the photovoltaic module 20 is further adapted to be wound around on at least a portion of the mast of the circumference 12. The circumference of the pole 12 corresponds to the cylindrical surface of the mast 12.

Preferably, as in the particular case of Figure 1, the photovoltaic module 20 is wound around the entire circumference of the mast 12.

The cells of the photovoltaic module 20 are arranged perpendicular to the vertical axis Z, that is to say to the horizontal, so that no cell is fully shaded during the displacement of the light source (usually the sun) to during the day allowing a continuous supply of the device 14.

This helps to collect light in all directions. Thus, contrary to non-flexible technology, there is no need for a follower (also known under the English name "sun tracker") to the photovoltaic module 20 receives light throughout the day .

The dimensions of the photovoltaic module 20 determines the electrical performance of the photovoltaic module 20. Thus, the dimensions of the photovoltaic module 20 are determined according to the energy needs of the light unit 18, and the average irradiance in the geographical site in which the device 14 is installed.

For example, a light unit 18 with a daily consumption of 5 watts per hour, it is considered that the average energy output of the photovoltaic module 20 is at least twice the energy requirement of the light unit 18 in order to ensure the necessary even on days with lower irradiance, or 10 Watts per hour. For example, for electrical performance of the photovoltaic module 20 of 60 Watts peak / m 2 , it may be determined that a dimension of 600 mm along the axial direction Z corresponds to the desired energy requirement.

When the photovoltaic module 20 is wrapped around the mast 12, the photovoltaic module 20 defines on the mast 12, an area having a size between 10 mm and 1 meter along the axial direction Z.

According to the example of Figure 1, the area bounded by the photovoltaic module 20 of the mast 12 has a size of 600 mm along the axial direction Z.

For example, it may be envisaged to use a photovoltaic module with dimensions of 600 mm by about 450 mm.

For the following, it is set to the photovoltaic module 20, a distal end

24 and a proximal end 26, distal end 24 being the most far end of the light unit 18.

In the particular case of Figure 1, each of the ends 24 and 26 corresponds to a curve (in this case a circle) on the mast 12.

The support 22 is adapted to maintain the photovoltaic module 20 wound on at least a portion of the circumference of the mast 12 and preferably over the entire circumference of the mast 12 as shown in Figure 1.

The support 22 comprises a protective wall 28 adapted to protect the photovoltaic module 20, a ring 30 and two holding members 32, 34.

The protective wall 28 is adapted to isolate the photovoltaic module 20 from the outside. In particular, the protective wall 28 is able to protect the photovoltaic module 20 from the weather that could damage the photovoltaic module 20.

According to the example of Figure 1, the protective wall 28 covers the entire of the photovoltaic module 20 so as to form a coating layer positioned on the photovoltaic module 20.

Furthermore, according to the illustrated specific case, the protection wall 28 is in the form of a film.

By way of example and without limitation, the protective wall 28 is made of a material selected from poly (methyl methacrylate) (often abbreviated as PMMA acronym of poly (methylmethacrylate)), glass or transparent resin .

The ring 30 is adapted to act as a clamping ring or finish.

The ring 30 is located at the distal end 26 of the photovoltaic module 20.

The ring 30 extends in a plane perpendicular to the axial direction Z. Such a scheme is called radial plane in the following description.

The ring 30 has the shape of a circle.

According to the example of Figure 1, the ring 30 is made of a plastic material.

According to another embodiment, the ring 30 is made of metal, especially steel or aluminum.

Alternatively, the ring 30 is made of a flexible material such as rubber or resin.

The two holding members 32, 34 are adapted to connect the ring 30 to the light unit 18.

In addition, the two holding members 32, 34 are adapted to ensure a sealing function of the protective wall 28.

According to the example of Figure 1, the two holding members 32, 34 extend between the distal end 26 of the photovoltaic module 20 and the proximal end 20 of the photovoltaic module.

As seen in FIG 1, the two holding members 32, 34 are straight. In addition, the two holding members 32, 34 are diametrically opposed with respect to the mast 12.

For example, each of the two holding members 32, 34 is made of a flexible material. Typically, a rubber or silicone seal is possible.

The light unit 18 is configured to be secured to the mast 12.

The light unit 18 is adapted to provide a lighting function of the environment of the mast 12.

The light unit 18 is also adapted to perform a function of managing electrical energy and electrical energy storage.

The light unit 18 includes a housing 36, a storage unit 38, a regulator 40 and a light emitting member 42.

In Figure 2, the storage member 38 and the regulating member 40 are shown in dashed lines and in the interest of clarity, positioned in the middle of the housing 36.

Those skilled in the art will understand that the position illustrated in Figure 2 is purely schematically, the storage member 38 and the regulating member 40 being around the mast 12.

The housing 36 comprises a body 44, a protective wall 46, the storage member 38 and the regulating member 40.

The body 44 has an upper portion 48, a bottom 50 and a middle portion 52 defined by the upper portion 48 and lower portion 50.

The middle part 52 has the shape of a circular cylinder. The generatrix of the cylinder extends over a height of at least 150 mm, preferably between 150 mm and 250 mm. Preferably, the height of the generatrix of the cylinder is 200 mm.

The body 44 has two portions, a first portion 54 and second portion 56.

Preferably, the first portion 54 and second portion 56 are substantially identical, so that each part 54, 56 has a shape of a half cylinder.

The first part 54 is connected to the second portion 56.

For example, as seen in FIG 3, the first portion 54 is connected to the second portion 56 by a screw / nut system.

Alternatively, a clip system, "male" Recessed - "female" are also conceivable.

According to one embodiment, the first portion 54 is configured to be connected to the second portion 56 by a recess "male" - "female" in a direction perpendicular to the axial direction Z.

Alternatively, the system providing the mechanical connection between the first part 54 and second part 56 also makes it possible to establish electrical connection between the regulating member 40 and the storage member 38. For this, by way of example , each part 54 and 56 comprises a portion of conductive track, the two portions of conductive track forming a conductive path by establishing the mechanical connection.

When the first portion 54 and second portion 56 are connected, the body 44 defines a recess 58 of complementary shape to the central mast 12.

Alternatively, the recess 58 is delimited by one of the two parts 54, 56, for example the second portion 56.

The body 44 is made of a plastic material.

According to another example, the body 44 is made of metal, for example steel or aluminum.

According to another example, the body 44 is made of a flexible material such as rubber or resin.

The upper part 48 has a seal.

The seal is made of a material such as a flexible rubber sheet, a rubber profiled element or a silicone gasket.

The middle portion 52 comprises the light emitting member 42, a first shielding wall 62 of the light emitting member 42, the joints of the protective wall 64 and a protective wall 66 of the body management.

Alternatively, the middle section 52 comprises at least two light emitting members 42 and at least one protective wall of the light emitting members 42. In some cases, the middle portion 52 can be sized to protect the all the light shielding members 42.

The first shielding wall 62 is alternatively made of glass.

According to another example, the first shielding wall 62 is formed with a transparent resin.

The second shielding wall 66 is made of plastic, the plastic may be opaque or not.

Alternatively, the second shielding wall 66 is made of polycarbonate.

According to another example, the second shielding wall 66 is made of glass.

In yet another example, the second shielding wall 66 is made of metal such as steel or aluminum.

The storage member 38 is capable of storing the electrical energy produced by the power unit 16.

For example, the storage member 38 is a lithium / ion.

The ability of the storage member 38 is determined according to the energy requirements of the light unit 18.

The ability of the storage member 38 is, for example, of 2000 mAh (milliamp hours)

The regulator 40 is adapted to regulate the charge of the storage member 38.

For example, the regulating member 40 is adapted to measure the state of charge

(Also designated by the acronym for SOC state of charge) of a battery.

The light emitting member 42 is powered by the storage member 38.

According to the example of Figure 1, the light emitting member 42 extends over the periphery of the housing 36.

According to the example of Figure 1, the light emitting member 42 is a light band extending over substantially all the periphery of the housing 36, except where a seal is located providing a seal.

For example and without limitation, the light emitting member 42 is a set of light emitting diodes (also designated by the acronym LED for light emitting diodes).

For example, the LEDs are distributed along a line surrounding the mast 12 around the axial direction Z. According to one embodiment, the line defines a flat disc perpendicular to the axial direction Z.

According to one embodiment, LEDs are equally spaced angularly along the line, that is to say that each LED is equidistant from the nearest two LEDs. In other words, each angle formed by two consecutive light emitting diodes and the axis of the mast 12 is equal to each other angle thus formed.

Light emitting diodes are, for example, distributed along the periphery of the housing 36 so as to surround the mast 12 of 360 degrees. Thus, whatever the orientation around the Z-axial direction of the housing 36 relative to an observer, at least one electroluminescent diode is visible at each time of the observer.

Alternatively, the LEDs are distributed along at least two lines surrounding the mast 12 around the axial direction Z.

For example, light emitting diodes are angularly equispaced along each line. The angle between two consecutive LEDs in the same row and the axis of the mast 12 has an angle value. The angle value is, for example, the same for each line considered. Alternatively, the angle value associated with at least one row is different from the angle value associated with at least another row.

According to one embodiment, the light emitting diodes of each line are distributed along a portion of the periphery of the housing 36.

For example, the light emitting diodes of each line are distributed over an angle of between 60 degrees and 180 degrees. This means that the angle formed by a first segment through a first light emitting diode belonging to a line and the axis of the mast 12 and a second segment through a second diode

emitting belonging to the same line and the axis of the mast 12, the two being considered emitting diodes LEDs forming between them the largest angle is between 60 degrees and 180 degrees.

The device 14 is then adapted to directional signage. This means that the LEDs are visible only for certain orientations of the housing 36 relative to the observer.

The operation of device 14 is now described.

In operation, the device 14 is fully autonomous since day, the sun illuminates the photovoltaic module 20. The photovoltaic module 20 converts light energy from the sun into electrical energy.

The electrical energy produced by the photovoltaic module 20 is then stored in the storage member 38.

When lighting is desired (e.g., overnight), the storage member 38 supplies the light emitting member 42. The light emitting element 42 then emits light.

The device 14 presents the advantage of having a relatively low mass. The total mass of the device 14 is less than 5 kg, typically around four kilograms.

The power supply of the light emitting member 42 is also autonomous and renewable since it is solar energy.

The device 14 fits, moreover, in any type of mast 12 with any shape (circular cylinder, oval or polygonal base basis).

In addition, the device 14 can be mounted at any height.

The establishment of such a device 14 does not generate any impact and / or no damage to the mast 12 on which the device 14 is installed.

The light is captured by the photovoltaic module 20 regardless of the orientation of the photovoltaic module 20 on the mast 12.

In addition, the beacon and the light contrast is visible to any position of the person looking at the system 10.

In addition, the device 14 is protected vis-à-vis the external aggressions, in particular thanks to the different walls.

In addition, the installation and removal of the mast 12 are easy which facilitates maintenance of the device 14.

For example, the ease of installation and / or removal can be illustrated with a method of installing the device on the mast 12.

For example, such a method comprises the following steps: winding the photovoltaic module 20 on the mast 12, assembling the two parts 54 and 56 of housing 36 and engage the housing 36 on the mast 12, electrically connecting the storage member 38 contained in one of the two parts 54 and 56 of housing 36 with the regulating member 40 contained in the other portion 54 and 56 of housing 36.

The method also comprises a step of providing an electrical connection between the photovoltaic module 20 and the regulating member 40, for making an electrical connection between the light emitting member 42 and the regulating member 40 , the assembly support 22 holding, for fixing the support 22 within the housing 36 and clamping rings 30 or the part of the support 22.

It becomes clear that such a process is much easier than implementing the methods of the prior art since only elements specific to the device 14 are involved in the installation of the device 14 on the mast 12.

In addition, the device 14 has the advantage of being easily scalable.

Such modularity allows such an evolution of the device 14. In some cases, such a development takes different forms. In particular, a modification of the number of luminous unit 18 is possible, each light unit being adapted to perform different functions. Typically, a light unit 18 provides a tagging feature while another light unit 18 provides an illumination function of information.

According to another example, a change in the number of electrical unit 16 allows an adaptation to the energy requirements of the lighting units or 18. Such an adaptation is particularly useful turns out on addition of a light unit 18 or sub -Sizing initial energy needs of the light units or 18 of the device 14.

The modularity of the device 14 is illustrated by example with the aid of Figures 5 to 7.

In the example of Figure 5, the device 14 comprises two power units 16 instead of a single power unit 16 as in the example of Figure 1.

In the configuration shown, the light unit 18 is arranged between the two electrical units 16.

In the example of Figure 6, the device 14 also comprises two power units 16 instead of a single power unit 16 as in the example of Figure 1.

In the configuration shown, the two power units 16 are arranged on a same side with respect to the light unit 18.

In the example of Figure 7, the device 14 comprises two light units 18 instead of a single light unit 18 as in the example of FIG 1.

In the configuration shown, the electrical unit 16 is arranged between the two light units 18.

Such modularity of the device 14 is permitted by the fact that the different units 14 and 16 are combined by fitting a projecting portion of a unit 14, 16 in a corresponding groove of another unit 14, 16.

As explained above, the modularity of the device 14 allows it to adapt easily to changes in needs, using the device 14 in place on the mast 12. For example, needs changes correspond to a change in function of the mast 12 and / or an energy need for change. Adapting to a new need may be by a simple evolution of the device 14. For example, there is added an additional 18 light unit to increase the amount of light generated.

In addition, according to a variant, the device 14 comprises a plurality of light emitting bodies, one of these light emitting bodies being the light emitting member 42 extending along the periphery of the housing 36 .

The first thickness e 1 is uniform. The first thickness e 1 is between 0.5 mm and 2 mm.

According to one embodiment, the first track 72 is in line with the second portion 84, that is to say, the first track 72 is in contact with the second portion 84 and the shape of the second portion 84.

For example, the first track 72 is cylinder-shaped annular base, the axis of the first track 72 being parallel to the axial direction Z.

The axis of an annular or circular base cylinder is defined as a line parallel to the generatrix of the cylinder and passing through the center of the circle or annulus which forms the cylinder director.

The first track 72 is, for example, formed by the union of two track portions each borne by one of the first portion 54 and second portion 56.

The second track 74 is, for example, formed by the union of two track portions each borne by one of the first portion 54 and second portion 56.

The second track 74 is interposed between the first track 72 and the shoulder 82.

The second track 74 is not electrically connected to the first track 72.

For example, the first track 72 and second track 74 are parallel to each other, and the distance between the first track 72 and second track 74, measured in the axial direction Z is greater than or equal to 1 mm .

The first connector 76 is configured to electrically connect the first track 72 to the storage member 38 or the regulating member 40.

The second connector 78 is configured to electrically connect the second track 74 to the storage member 38 or the regulating member 40.

The seal 79 is configured to isolate the first track 72 and second track 74 from the outside of the upper portion 48.

The seal 79 is configured to provide a seal between the upper part 48 and the photovoltaic module 20. In particular, the seal 79 is configured to prevent water flowing down along the outside of the photovoltaic module 20 of achieve the first track 72 and second track 74.

The photovoltaic module 20 includes a positive electrode and a negative electrode.

The photovoltaic module 20 is configured to impose an electrical potential difference, when the photovoltaic module 20 is illuminated by the sun, between the positive and the negative electrode.

The proximal end 26 has been shown in phantom in Figure 8.

The support 22 comprises a third connector 86 and a fourth connector 88.

Each of the third connector 86 and the fourth connector 88 is fixed to the support 22. For example, each of the third connector 86 and the fourth connector

88 is glued to the support 22. Alternatively, each of the third connector 86 and the fourth connector 88 is embedded in a rigid portion of the support 22.

The third connector 86 is configured to electrically connect the first track 72 to one of the positive electrode and the negative electrode.

The fourth connector 88 is configured to electrically connect the second track 74 to the other of the positive electrode and the negative electrode.

For example, each of the third connector 86 and the fourth connector 88 is connected to the corresponding electrode by a cable. The connection cable is, e.g., welded to the connector 86, 88 and the corresponding electrode.

Alternatively, each of the third connector 86 and the fourth connector 88 is connected to the corresponding electrode by a flexible printed circuit

The third connector 86 and the fourth connector 88 are each configured to permit relative rotation of the photovoltaic module 20 and its support (22) relative to the upper portion 48 around the axial direction Z.

For example, each of the third connector 86 and the fourth connector 88 is provided to be elastically deformable in a relative rotation of the photovoltaic module 20 and the upper portion 48 around the axial direction Z.

According to the example of Figure 8, each of the third connector 86 and the fourth connector 88 is made from a folded rectangular metal strip to form a hook.

Each of the third connector 86 and the fourth connector 88 is made of a metallic material. For example, each of the third connector 86 and the fourth connector 88 is made of a conductive material. The conductive material is, for example, selected from the group consisting of copper, silver and aluminum

Each of the third connector 86 and the fourth connector 88 comprises a third portion 90, a fourth portion 92, a fifth portion 94 and a sixth portion 96.

Each of the third connector 86 and the fourth connector 88 has a width, measured along a perimeter of the second portion 84, between 2 mm and 10 mm.

Each third portion 90 is parallelepipedal. The third portion has a length, measured in the axial direction Z, between 20 mm and 50 mm.

When the photovoltaic module 20 and the light unit 18 are installed on the mast 12, each third portion 90 is interposed between the proximal end 26 and the mast 12.

Each fourth portion 92 is parallelepipedal.

Each fourth portion 92 is defined by the third portion 90 and the fifth portion 94.

Each fourth portion 92 is perpendicular to the corresponding third portion 90. Each fourth portion 92 is perpendicular to the axial direction Z.

Each fourth portion 92 has a length, measured in a radial direction, between 2 mm and 10 mm.

When the photovoltaic module 20 and the light unit 18 are installed on the mast 12, each fourth portion 92 is interposed between the proximal end 26 and the shoulder 82.

When the photovoltaic module 20 and the light unit 18 are installed on the mast 12, each fifth portion 94 is interposed between the proximal end 26 and the second portion 84.

Every fifth portion 94 is delimited by a first edge 98 and a second edge 100.

Each first edge 98 belongs to both the fourth portion 92 and the fifth portion 94 corresponding.

Each second ridge 100 belongs both to the fifth portion 94 and the sixth portion 96 corresponding.

For each third connector 86 and each fourth connector 88, the furthest point from the axis of the second portion 84 in the radial direction is part of the corresponding second edge 100. In other words, a segment contained in a plane containing the axis of the second portion 84 and connecting the first edge 98 to the second edge 100 forms with a segment of the fourth portion 92 contained in the same plane an angle strictly greater than 90 degrees. The angle is considered then the smaller of the two angles defined by the two segments considered.

Each second ridge 100 abuts against one of the first track 72 and second track 74.

The fifth portion 94 defines with the third portion 90, the fourth portion 92 and respective sixth portion 96, a convex volume surrounding at least partially the proximal end 26.

The sixth portion 96 has an end. The end of the sixth portion 96 is opposite to the second edge 100.

The sixth portion 96 is bounded by the second edge 100 and by the end of the sixth portion 96.

The end of the sixth portion 96 bears against the proximal end 26.

Every sixth portion 96 is configured to electrically connect the corresponding electrode and the track 72, 74 correspondingly.

The sixth portion 96 and the fifth portion 94 are configured so that, when the photovoltaic module 20 and the light unit 18 are installed on the mast 12, the sixth portion 96 and the fifth portion 94 exert a spring force tending to press the second edge 100 against the track 72, 74 correspondingly.

For example, when the photovoltaic module 20 and the light unit 18 are installed on the mast 12, each of the first track 72 and second track 74 exerts on the corresponding second edge 100 a force causing elastic deformation of the sixth portion 96 and corresponding fifth portion 94.

The device 14 then enables a relative rotation between the light unit 18 and the photovoltaic module 20, while maintaining an electrical connection between it and the latter.

The device 14 therefore makes it possible to modify the orientation of the photovoltaic module 20, in particular for orienting it in a favorable manner relative to the sun, without changing the orientation of the light unit 18.

In addition, the electrical connection between the photovoltaic module 20 has a reduced size and is easy to achieve, since it does not involve the connection of power cables: the only positioning of the proximal end 26 against the shoulder 82 can drive the electrical connection between the photovoltaic module 20 and the light unit 18.

A third embodiment of a device 14 according to the invention is shown in Figure 9. The elements identical to the second embodiment of Figure 8 are not described again. Only differences are highlighted.

The second portion 84 includes a first rod 102 and second rod 104.

Each rod 102, 104 is a continuous strip of material extending from the second portion 84 towards the mast 12 when the light unit 18 is installed on the mast 12.

According to one embodiment, each wand 102, 104 surrounds the mast 12 at least 180 degrees.

Each wand 102, 104 has, for example, a parallelepipedal section. The first rod 102 is interposed between the first track 72 and second track 74.

The rods 102, 104 are configured to cooperate with each other to guide the third connector 86 upon relative rotation between the light unit 18 and the photovoltaic module 20, such that the third connector 86 remains in electrical contact with the first track 72 during the rotation.

The first rod 102 is further configured to cooperate with the shoulder 82 to guide the fourth connector 88 upon relative rotation between the light unit 18 and the photovoltaic module 20, such that the fourth connector 88 remains in electrical contact with the second track 74 during the rotation.

Each of the third connector 86 and the fourth connector 88 is cylindrical with a circular base, and the generatrix of each of the third connector 86 and the fourth connector 88 is parallel to a radial direction of the second portion 84.

Each of the third connector 86 and fourth connector 88 has a diameter of between 2 mm and 10 mm.

Each of the third connector 86 and fourth connector 88 has a base 106 and a contact end 108. Each of the third connector 86 and the fourth connector 88 is delimited in a radial direction of the second portion 84 by the base 106 and the contact end 108.

Each base 106 is configured to secure the connector 86, 88 corresponding to the proximal end 26.

Each contact end 108 is hemispherical. Each contact end 108 is intended for bearing against the track 72, 74 correspondingly when the photovoltaic module 20 and the light unit 18 are installed on the mast 12.

The rods 102 and 104 are then used to fasten more strongly the electrical unit 16 to the light unit 18. The rods 102 and 104 involved in keeping the module 20 and its support 22 in position relative to the housing 36.

In addition, the rods 102 and 104 also allow a better hold in position the third and fourth connectors 86 and 88 and thus a more reliable electrical connection between the third and fourth connectors 86 and 88 and tracks 72 and 74.

The connection surface between the third and fourth connectors 86 and 88 and tracks 72 and 74 is also increased.

According to another example device 14, the device comprises a clamp adapted to grip the pole 12. The shape clamp for example, when the clamp is clamped to the mast 12, a support for the housing 36.

The device 14 is particularly adapted to be fixed to a non-cylindrical mast, in particular a conical mast.
