Definitions
- the present invention relates to a fence with a device for lighting a field, and more particularly a lighting device specially adapted for sports fields.
- Such a device particularly applies to the lighting of sports fields located outdoors.
- Practicing a sport on a dedicated field most often requires good visibility.
- the latter most often regulates the characteristics of the terrain on which the sport is practiced. It can thus impose precise dimensions for the land, as well as other characteristics, such as for example the lighting characteristics of the land.
- This is the case, for example, of tennis federations which impose, through standards, the dimensions of tennis courts or courts and, for courts to be used at night or without natural light, the characteristics of the lighting, and in particular the intensity of the lighting on the different points of the ground and the homogeneity of this lighting on the ground.
- lighting devices For sports fields located inside buildings (usually referred to by the English term “ indoor "), lighting devices include lamps or projectors which are generally attached to the ceiling or to the structure of the buildings, in order to 'properly light the grounds.
- the lighting of the fields is generally provided by lamps or projectors placed at the top of support masts, installed around the field, such as the shows for example the document US 4,141,056 .
- These support poles must be of great height to allow the floodlights to have sufficient distance to illuminate the terrain evenly.
- floodlights illuminating the courts can be a source of glare or glare.
- a flash of light occurs when a light source, without necessarily dazzling a person, produces an afterglow in their home, which can in particular be annoying when practicing sport.
- the use of projectors located at a great height makes it possible to limit this disadvantage, by allowing the projectors to be aligned with the player's line of vision only in a reduced number of cases.
- the floodlights Once the floodlights are installed on the masts, their orientation must be adjusted, at night, by a first technician, assisted by a second technician present on the ground to measure the intensity of the lighting at different points on the ground.
- the precision required for this adjustment is all the more important as the height of the mast carrying the projectors is low. Indeed, when the lighting has a lower angle of incidence in relation to the illuminated terrain, it is more difficult to obtain homogeneous lighting that meets standards.
- the lighting devices therefore most often install very high masts to obtain satisfactory homogeneity of lighting and to limit the dazzling of the players.
- the installation of these support masts which must be strong enough to withstand the wind, represents significant and expensive work, generally requiring the obtaining of a building permit, which the owners of sports grounds are not always aware of. ability to achieve.
- a large number of outdoor sports grounds, including tennis courts, are therefore not lit and can only be used during the day.
- the floodlights located on the support masts develop significant power, therefore resulting in high electricity consumption.
- these floodlights often generate significant light pollution, providing lighting around the pitch that may not be desired.
- certain tennis courts are lit by strips of fluorescent tubes extending along the courts, which can be carried by the poles. fence of the land or by a dedicated structure, as in the document US 4,270,161 . Due to the nature of the light sources and the proximity between the booms and the ground, the light cannot be distributed over the ground with the desired level of intensity and homogeneity. Such a system therefore does not make it possible, for example, to fulfill the conditions imposed by tennis federations for courts hosting official competitions. Additionally, the lighting provided by these ramps is often a source of glare or flash of light for players.
- the present invention aims to overcome these drawbacks of the prior art.
- the present invention aims to provide a device for lighting a field, and more particularly a sports field, which requires a reduced installation cost compared to the lighting solutions generally used.
- Another objective of the invention is to provide such a lighting device which offers great homogeneity of lighting, thus meeting demanding normative constraints.
- Another objective of the invention is to provide such a lighting device whose installation and adjustments are simplified compared to the solutions of the prior art.
- Yet another objective of the invention is to provide such a lighting device which is well suited to the practice of the sport concerned, and in particular which limits as much as possible the risks of dazzling or flashing of light of athletes or athletes. players, and which limits the shadows cast on the field.
- the diffusion angle of a light beam is considered to be the diffusion angle of the width at half height (width of the beam in which the light intensity is at least equal to the maximum intensity, more commonly designated by the English expression “ full width of half maximum ” or by the acronym FWHM) of the beam.
- Such a device presenting a ramp of very directive light sources oriented parallel to each other makes it possible to effectively illuminate a site, even when the ramp is placed at a low height, without generating dazzling of people placed on this site, if they do not are not facing the ramp.
- This device is therefore very suitable for lighting sports fields, particularly fields dedicated to the practice of sports in which the players or athletes are mainly oriented in a preferential direction. In the latter case, the lighting strip(s) may preferably be parallel to this preferred direction.
- the ramp or at least one of the ramps, can be placed at a predefined height relative to said terrain.
- This height can for example be predefined when the grounds have standardized dimensions, and the ramp can be fixed to an element of the land, such as the fences of the land.
- this height of the ramp is relatively low, compared to the dimensions of the land to be illuminated, such that the beams of the light sources are preferentially oriented in directions having angles of less than 25° with the horizontal.
- the ground-level lighting thus produced helps avoid dazzling players and limits energy consumption.
- the ramp extends over most of the length of said side of the land. This arrangement allows the ramp to effectively illuminate the entire useful portion of the land.
- the device comprises at least two lighting strips, facing each other along two opposite parallel sides of said terrain. These two lighting lamps make it possible to obtain better homogeneity of lighting and to limit cast shadows.
- the orientation of said light sources relative to said ramp(s) is invariable. This solution, which can be implemented for lighting grounds with predefined dimensions, simplifies the installation of the device, the orientation of the light sources being adjusted in advance and not being intended to be modified during or after the 'facility.
- the position of said ramp(s) relative to the terrain is predetermined as a function of the dimensions of said terrain and the characteristics of the desired lighting.
- said or at least one of said ramps has means for fixing to posts located along said side of the land.
- the ramps can thus be easily assembled to pre-existing elements on the ground.
- said fixing means comprise rails, extending over the entire length of said ramp, capable of holding a fixing element at any point along the length of said ramp.
- said or at least one of said ramps is composed of several independent ramp segments, assembled together.
- said ramp segments are assembled by fixing elements held by said rails of each of said ramp segments.
- the light sources of said or at least one of said ramps are oriented in at least two directions distinct. These different orientations of the lamps ensure good distribution of light on the ground.
- said or at least one of said ramps has at least two distinct supports each capable of receiving light sources oriented parallel in a predetermined direction.
- each of said supports extends over the entire length of said or at least one of said ramps.
- the light sources can thus be distributed in several orientations over the entire length of the ramp.
- said ramp or at least one of said ramps comprises a metal profile comprising said fixing means and at least one flat surface forming a support capable of receiving light sources oriented parallel in a predetermined direction.
- a metal profile has good mechanical characteristics. It can also participate effectively in the dispersion of the heat emitted by light sources.
- the device comprises at least two lighting strips extending substantially parallel to each other along the same side of said ground, the light sources of at least two of said strips being oriented in distinct directions, perpendicular to the longitudinal direction of said ramps. Secondary lighting strips can thus ensure, on certain parts of the field, the lighting of useful volumes for the practice of the sport concerned.
- said light sources are lamps comprising light-emitting diodes.
- a lighting strip capable of being implemented in a lighting device as described above, comprises fixing means capable of allowing its fixing to posts, in a horizontal position, said fixing means comprising rails (417, 418), extending over the entire length of said ramp (4), capable of holding a fixing element at any point along the length of said ramp (4), the lighting ramp comprising a succession of light sources distributed along its length, each of said light sources projecting a light beam having a diffusion angle less than 20°, oriented perpendicular to the longitudinal direction of said ramp, a part of said light sources having a first non-modifiable orientation, relative to said ramp, and another part of said light sources having a second orientation, distinct from said first orientation and non-modifiable, for example relation to said ramp.
- This lighting strip can advantageously have one or more of the characteristics mentioned above.
- figure 1 is a plan of a sports field dedicated to the practice of tennis. This terrain is also represented in perspective by the figure 2 . It was built and fitted out in accordance with the normative requirements imposed by the tennis federations to be able to host competitions.
- This land has a surface 1, on which lines 11 are drawn in white paint.
- the rectangular surface surrounded by lines 11 constitutes the playing area 10, or court.
- the playing area 10 is separated in two by a net 2 stretched between two vertical posts 21 and 22, arranged on either side of the playing area 10.
- the lines 11 and the net 2 define the main axis 100 of the field, which extends perpendicular to the plane defined by the net 2, separating the playing area 10 into two equal parts.
- the exterior lateral lines 111 and 113 of the playing area which are parallel to the main axis 100 of the field while being furthest from this axis, form the lateral limits of the playing area 10.
- the end lines of court 112 and 114 which are parallel to the net 2 while being furthest from the net, form the bottom limits of the playing area 10.
- the playing area has a length of 23.77 meters and a width of 10.97 meters.
- the players are placed on both sides of the net 2, generally in the playing area 10 or behind the baseline lines 112 and 114, and are mainly oriented in a direction substantially parallel to the main axis 100 of the land.
- the surface 1 of the court has a rectangular shape whose sides are parallel to the limits of the playing area 10. To comply with the standards set by the tennis federations, this surface preferably has a length of 36 meters and a width of 18 meters.
- This surface 1 is surrounded by a fence 3, constituted by a mesh 35 supported by fence posts 30 (only some of these posts 30 are numbered in the figures) surrounding the four sides of surface 1 of the land.
- each of the side fences (31 and 33 respectively) is generally located at a distance of 3.5 meters from the nearest side boundary (111 and 113 respectively).
- each of the baseline fences (32 and 34 respectively) is located at a distance of approximately 6 meters from the nearest baseline (112 and 114 respectively).
- FIG. 3 represents the side fence 33 in more detail.
- the posts 30 holding the fence 35 to form the fence 3 are aligned at regular intervals. Conventionally, these posts are spaced from each other at a distance of between 3 meters and 3.6 meters. Of course, a door (not shown in the figures) is normally provided in this fence.
- fence 3 extends vertically to a height of at least 3 meters, generally between 3 meters and 3.50 meters. To support this fence, the posts 30 therefore extend vertically to a height of at least 3 meters.
- the tennis court represented by the figures 1 and 2 is equipped with a lighting device according to one embodiment of the invention, comprising two main lighting strips 4 and four secondary lighting strips 5.
- the side fence 31 and the side fence 33 each carry a light strip the main lighting 4, intended mainly to illuminate the play area 10, and two secondary lighting ramps 5, intended mainly to illuminate the balls moving at height.
- This lighting of the field by two ramps 4 placed on both sides of the field also makes it possible to greatly limit the shadows generated by the players on the field, which can disturb the players or spectators.
- the main lighting strips 4 extend horizontally along most of the length of the side fences 31 and 33. More precisely, these main lighting strips 4 extend, in the embodiment presented, over a length of 30.4 meters from the side fences 31 and 33, the total length of which is 36 meters. This length allows the main lighting strips 4 to face the entire length of the play area 10, which measures 23.77 meters.
- Each main lighting strip 4 has a longitudinal shape and is attached to the posts 30, on the side of these posts facing the ground, at a height of 3 meters.
- the posts 30 normally have a height of between 3 meters and 3.50 meters, the main lighting strips 4 are therefore fixed near their upper end.
- THE figures 4 And 5 show, respectively in perspective and in section, a portion of the main lighting strip 4.
- This lighting strip comprises a profile 41, made of aluminum in the embodiment shown, designed to be fixed to the posts 30 and to support lighting means.
- This profile 41 comprises two rails, a lower rail 417 and an upper rail 418, extending over its entire length and having a shape capable of retaining the head of a screw whose threaded portion would extend outside the profile.
- These two rails 417 and 418 are intended to be in contact with a vertical post. Their alignment therefore defines the vertical direction, when the main lighting strip 4 is in use configuration.
- the profile 41 also defines a lamp support housing, which is formed between two contiguous lamp support surfaces 411 and 412 and two protective wings, respectively a lower wing 413 and an upper wing 414. These two wings extend, respectively, from an edge of the lamp support surfaces, respectively 411 and 412, substantially perpendicular to these walls.
- the free ends of these wings 413 and 414 have grooves, respectively 4131 and 4141, making it possible to maintain a translucent wall 44, made of polycarbonate, closing the lamp support box (on the figure 4 , the wall 44 is only represented on part of the length of the ramp 4)
- Lamps preferably using LED technology (acronym for “ Light-Emitting Diode ” meaning “light-emitting diode”), are placed in the housing thus formed, at several points of the main lighting strip 4. Some of these lamps, called “far lighting lamps” 42, are fixed on the surface of support 411. The other lamps, called “near lighting lamps” 43, are fixed on the support surface 412.
- these lamps 42 and 43 are glued to the support surfaces 411 and 412 by means allowing heat transfer between the lamps and the profile 41.
- the profile 41 which is preferably metallic, can thus participate effectively in the dispersion heat produced by the lamps.
- the far lighting lamps 42 and the near lighting lamps 43 are identical. They may, however, be different in other embodiments.
- These lamps 42 and 43 are constituted by an electronic card, respectively 421 and 431, of which a flat surface is intended to be glued to a support and the other surface of which has a light-emitting diode (not visible in the figures) covered by a block optical, respectively 422 and 432.
- These optical units 422 and 432 act as a lens concentrating the light emitted by the diodes into a light beam.
- part of the lamp support housing can be covered with resin, in order to protect the lamps from dust and water.
- the resin covers the base of each of the lamps, and in particular the electronic card 421 or 431, and the base of the optical unit 422 or 432.
- the portion of the optical unit emitting the light beam is not covered of resin. In this particular embodiment, it is not necessary to close the lamp support box with the translucent wall 44, the lamps being sufficiently protected by the resin.
- the diffusion angle in the present application, is the diffusion angle of the width at half height (width of the beam in which the light intensity is at least equal to the maximum intensity, more commonly referred to by the English expression " fluil width of half maximum " or by the acronym FWHM) of the beam.
- Other types of beams can be used, but it is necessary, to avoid the risk of glare or of light burst, that the beam diffusion angle is less than 20°.
- the optical units 422 and 432 are designed to direct the beams, respectively 429 and 439, in a direction, respectively 420 and 430, perpendicular to the flat surface of the electronic cards 421 and 431, and therefore perpendicular to the support surfaces, respectively 411 and 430. 412, of the profile 41.
- These support surfaces 411 and 412 have orientations chosen, depending on the terrain to be illuminated, the lamps used and the position of the ramp relative to the terrain, to offer a homogeneous distribution of light on the ground.
- the orientation of the surfaces 411 and 412 is chosen for the case of a ramp comprising the lamps described above, placed at a height of 3 meters on the fence posts of the tennis court to be illuminated.
- the surface 411 has an orientation such that the beam emitted by the distant lighting lamps 42 is oriented in the direction 420, forming an angle ⁇ 1 equal to 78° with vertical, when the ramp 4 is in its configuration of use.
- the surface 412 has an orientation such that the beam emitted by the near lighting lamps 43 is oriented in the direction 430, forming an angle ⁇ 2 equal to 66° with the vertical, when the ramp 4 is in its configuration of use.
- the beams are oriented in directions perpendicular to the longitudinal direction of the ramp 4, therefore perpendicular to the main axis 100 of the terrain.
- FIG. 6 represents the lighting produced by a far lighting lamp 42 and a near lighting lamp 43 of one of the ramps 4 on the tennis court.
- This lamp 43 only illuminates a restricted portion of the play area 10, located immediately in front of the lamp 43 and extending in a direction perpendicular to the main axis of the field 100.
- a player playing on the playing area 10 does not risk having his eyes in the light beam 439, and therefore of be dazzled or suffer a burst of light, only if it is at the extreme edge of the playing area 10, and is oriented towards this lamp, therefore perpendicular to the main axis 100. This situation is extremely rare when playing tennis.
- the light beam 429 and the light spot 4290 produced by a single distant lighting lamp 42.
- the lamp 42 being oriented in a direction closer to the horizontal than the lamp 43, the light spot 4290 is further away from the ramp 4 , and therefore more extensive and more diffuse. Due to the high directivity of the beam 429, this task 4290 however extends in a direction perpendicular to the main axis of the field 100 and remains limited to a small portion of the length of the playing area 10, located immediately in face of the lamp 42.
- a player playing on the playing area 10 only risks having his eyes in the light beam 429, and therefore being dazzled, if he is in the area of the edge of the playing area 10 and is oriented towards this lamp, therefore perpendicular to the main axis 10. This situation is very rare during tennis practice.
- the beams produced by the lamps 42 and 43 carried by the ramps 4 can therefore only dazzle a player in very rare cases when playing tennis.
- lamps 42 and 43 are placed, in the ramp 4, at substantially regular intervals.
- the ramp 4 presents, along its length, a lamp 42 or 43 approximately every 12 cm, alternating series of two near lighting lamps 43 and six far lighting lamps 42.
- the inventors have determined that this distribution of the lamps, with the characteristics, the orientations of the lamps and the positions of the ramps exposed above, made it possible to obtain an excellent distribution of lighting on an outdoor tennis court, satisfying the standards set by tennis federations for the organization of outdoor competitions. Furthermore, this regular distribution of the lamps makes it possible to generate an almost continuous lighting line all along the ramp 4.
- the lighting device shown comprises, in addition to the two main lighting strips 4, four secondary lighting strips 5 extending parallel to the main lighting strips 4. It should be noted that, in other modes of embodiment of the invention, the lighting device could include only one ramp, or one or two lighting ramps on each side of the field, or on the contrary a larger number of ramps.
- two secondary lighting strips 5 are placed below each of the main lighting strips 4. Each of these secondary lighting strips 5 measures 1.90 meters in length, and is hung centered on one of the posts 30 close to the posts 30 closest to the net 2. Thus, on each side of the field, two secondary lighting strips 5 are separated by several meters from each other, each being placed one side of the net 2.
- These secondary lighting strips 5 have a structure very close to that of the main lighting strips 4. They also include profiles, having fixing rails and lamp support boxes in which a lamp support surface, or several surfaces having different orientations are provided to support the lamps.
- the secondary lighting strips 5 are made from the same profile 41 as the main lighting strips 4. This profile is however placed in a reverse position, the wing 413 being placed upwards. and the wing 414 being placed downwards. The lamp support surfaces of this profile therefore have different orientations.
- each secondary lighting strip 5 only the surface 411 of the profile 41 constituting each secondary lighting strip 5 carries lamps. These lamps therefore emit a beam 50 oriented in a direction perpendicular to the main direction of the terrain and forming an angle of 102° relative to the vertical.
- the lamps used in this embodiment has a diffusion angle of 30°, much greater than the diffusion angle of the lamps used in the main lighting strips 4. They can however, in other embodiments, present characteristics different.
- the beam 50 which is shown on the Figure 6 for one of the lamps of one of the ramps 5, is therefore directed in a slightly upward direction.
- This beam allows good lighting of high balls when playing tennis.
- each of the ramps 5 has, along its length, a succession of lamps, such that the entire area located above the middle of the field, in which high balls are likely to pass, is illuminated by homogeneous manner.
- the orientation of the beams produced by this secondary lighting ramp 5 means that the lighting remains, in the majority of cases, above the players' heads. In the rare cases where the player may find themselves in the light beams of these Ramps 5, these beams are very dispersed and therefore are not likely to dazzle them or cause a burst of light.
- Each of the ramps 4 is composed of a plurality of segments, which are each completely equipped with lamps and the translucent wall.
- each ramp 4 is made up of eight segments of 3.80 meters each. This length of the segments, which is greater than the spacing generally observed between two successive fence posts 30, allows each of the segments to be secured to at least one of the posts 30.
- FIG. 8 shows the ends of two segments 491 and 492 of a ramp 4, which are secured using a connecting plate 6.
- This plate 6 placed against the lower 417 and upper 418 rails of each of the segments 491 and 492, has holes 61, 62, 63 and 64 placed opposite, respectively, each of the two rails of each segment.
- This plate 6 can be secured to the two segments 491 and 492 via bolts, the screw heads of which are inserted into the rails 417 and 418 and the rod of which passes through the holes 61, 62, 63 and 64 of plate 6.
- the hexagonal screw heads, inserted in the rails 418 and 417, are advantageously blocked in rotation by the rails, to allow the tightening of the nuts.
- the holes 63 and 64 have oblong shapes allowing the bolts to be moved along the rails 417 and 418, in order to avoid possible contact between the bolts and a fence post 30.
- FIG. 7 represents the assembly of a portion of ramp 4 on a fence post 30. This assembly is done via a fixing plate 7, placed against the post 30, on the side opposite the ramp 4.
- This plate fixing 7 has a shape adapted to rest on the post 30, and has four holes 71, 72, 73 and 74. This plate 7 can be brought closer to the ramp 4, by tightening the post 30, thanks to bolts whose screw heads are introduced into the rails 417 and 418 and the rods of which pass through the holes 71, 72, 73 and 74.
- ramps 4 and 5 can thus be carried out very easily by a simple assembly of bolts, without the need for cutting or drilling. It does not require any mast erection, as pre-existing fence posts are used. It can therefore be carried out quickly, and at a very low cost, by people who do not have any particular qualifications.
- Each of the sections of the ramp 4 comprises a set of electrical wires, not shown in the figures, allowing the power supply of each of the lamps.
- each segment of the ramp 4 has, at each of its ends, a single power connector, which can be connected to the corresponding connector of the adjacent section.
- the power supply wires of each section can therefore be assembled together very easily.
- the power connector can be connected to a power cable, making it possible to supply the electrical energy generated by a power supply box which can be placed at the foot of the fence 3
- a power supply box which can be placed at the foot of the fence 3
- Such an electrical box making it possible to power all the lamps of one or more ramps 4 or 5, can be connected to the standard electrical network. Indeed, lighting the terrain using very directive LED lamps located a short distance from the terrain to be illuminated consumes relatively little energy. The energy consumed is, in particular, much lower than the energy consumed by floodlights placed at the top of masts, due to the short distance between the light sources and the surface to be illuminated.
- a closing cover or a flange can be assembled to close the lamp support box.
- This cover or this flange can advantageously be fixed by screws inserting into the holes 415 and 416, provided for this purpose in the profile 41.
- the lighting device according to the invention does not require any adjustment after its installation.
- the ramps are placed in the position recommended by the manufacturer (3 meters in height on the side fences of the tennis court, for the main lighting ramps 4) and the tennis court to be illuminated has the dimensions recommended by the tennis federations, the orientation of the different lamps will be, without any adjustment, directly adapted to illuminate the court optimally.
- the constitution of the ramps also prevents any adjustment of the orientation of the lamps. The installation of the lighting device is therefore particularly simple.
- the lighting device is suitable for lighting a tennis court.
- other lighting devices according to the invention can be easily implemented to illuminate other types of rectangular grounds, for example fields dedicated to the practice of other sports.
- the implementation of the invention on other grounds will present a particular advantage when these grounds have standardized dimensions, allowing manufacturers to offer devices which adapt, without adjustment, to the lighting of the grounds.

Description
La présente invention concerne une clôture avec un dispositif d'éclairage d'un terrain, et plus particulièrement un dispositif d'éclairage spécialement adapté aux terrains de sport.The present invention relates to a fence with a device for lighting a field, and more particularly a lighting device specially adapted for sports fields.
Un tel dispositif s'applique particulièrement à l'éclairage de terrains de sport situés en extérieur.Such a device particularly applies to the lighting of sports fields located outdoors.
La pratique d'un sport sur un terrain dédié nécessite le plus souvent une bonne visibilité. Pour les sports dont la pratique est organisée par une fédération, celle-ci réglemente le plus souvent les caractéristiques du terrain sur lequel se pratique le sport. Elle peut ainsi imposer des dimensions précises pour le terrain, ainsi que d'autres caractéristiques, comme par exemple les caractéristiques d'éclairement du terrain. C'est le cas par exemple des fédérations de tennis qui imposent, par des normes, les dimensions des terrains ou courts de tennis et, pour les terrains devant être utilisés de nuit ou sans lumière naturelle, les caractéristiques de l'éclairage, et notamment l'intensité de l'éclairage sur les différents points du terrain et l'homogénéité de cet éclairage sur le terrain.Practicing a sport on a dedicated field most often requires good visibility. For sports whose practice is organized by a federation, the latter most often regulates the characteristics of the terrain on which the sport is practiced. It can thus impose precise dimensions for the land, as well as other characteristics, such as for example the lighting characteristics of the land. This is the case, for example, of tennis federations which impose, through standards, the dimensions of tennis courts or courts and, for courts to be used at night or without natural light, the characteristics of the lighting, and in particular the intensity of the lighting on the different points of the ground and the homogeneity of this lighting on the ground.
Pour les terrains de sport situés à l'intérieur des bâtiments (usuellement désignés par le terme anglais « indoor »), les dispositifs d'éclairage comprennent des lampes ou des projecteurs qui sont généralement fixés au plafond ou à la structure des bâtiments, afin d'éclairer correctement les terrains.For sports fields located inside buildings (usually referred to by the English term " indoor "), lighting devices include lamps or projectors which are generally attached to the ceiling or to the structure of the buildings, in order to 'properly light the grounds.
Pour les terrains de sport situés en extérieur (usuellement désignés par le terme anglais « outdoor »), l'éclairage des terrains est généralement réalisé par des lampes ou des projecteurs placés en haut de mâts de support, installés aux abords du terrain, comme le montre par exemple le document
Pour les sports imposant aux athlètes ou aux joueurs de regarder vers le haut, comme par exemple le tennis, les projecteurs éclairant les terrains peuvent être une source d'éblouissement ou d'éclat de lumière. Un éclat de lumière se produit quand une source lumineuse, sans nécessairement éblouir une personne, produit chez elle une image lumineuse rémanente, qui peut notamment être gênante pour la pratique du sport. L'utilisation de projecteurs situés à grande hauteur permet de limiter cet inconvénient, en permettant que les projecteurs ne soient alignés avec la ligne de vision du joueur que dans un nombre réduit de cas.For sports that require athletes or players to look upwards, such as tennis, floodlights illuminating the courts can be a source of glare or glare. A flash of light occurs when a light source, without necessarily dazzling a person, produces an afterglow in their home, which can in particular be annoying when practicing sport. The use of projectors located at a great height makes it possible to limit this disadvantage, by allowing the projectors to be aligned with the player's line of vision only in a reduced number of cases.
Une fois les projecteurs installés sur les mâts, il est nécessaire que leur orientation soit ajustée, de nuit, par un premier technicien, assisté par un second technicien présent sur le terrain pour mesurer l'intensité de l'éclairage en différents points du terrain. La précision nécessaire de ce réglage est d'autant plus importante que la hauteur du mât portant les projecteurs est faible. En effet, quand l'éclairage présente un angle d'incidence plus faible par rapport au terrain éclairé, il est plus difficile d'obtenir un éclairage homogène répondant aux normes.Once the floodlights are installed on the masts, their orientation must be adjusted, at night, by a first technician, assisted by a second technician present on the ground to measure the intensity of the lighting at different points on the ground. The precision required for this adjustment is all the more important as the height of the mast carrying the projectors is low. Indeed, when the lighting has a lower angle of incidence in relation to the illuminated terrain, it is more difficult to obtain homogeneous lighting that meets standards.
Les dispositifs d'éclairage mettent donc en place, le plus souvent, des mâts très élevés pour obtenir une homogénéité d'éclairage satisfaisante et pour limiter l'éblouissement des joueurs. L'installation de ces mâts de support, qui doivent être suffisamment solides pour résister au vent, représente des travaux importants et coûteux, nécessitant généralement l'obtention d'un permis de construire, que les propriétaires de terrains de sport ne sont pas toujours en capacité de faire réaliser. Un grand nombre de terrains de sport extérieurs, et notamment de courts de tennis, ne sont donc pas éclairés et ne peuvent être utilisés que durant la journée.The lighting devices therefore most often install very high masts to obtain satisfactory homogeneity of lighting and to limit the dazzling of the players. The installation of these support masts, which must be strong enough to withstand the wind, represents significant and expensive work, generally requiring the obtaining of a building permit, which the owners of sports grounds are not always aware of. ability to achieve. A large number of outdoor sports grounds, including tennis courts, are therefore not lit and can only be used during the day.
Par ailleurs, sur les terrains éclairés, les projecteurs situés sur les mâts de support développent une puissance importante entraînant donc une forte consommation électrique. De plus, ces projecteurs génèrent souvent une pollution lumineuse importante, en fournissant aux alentours du terrain un éclairage qui peut ne pas être souhaité.Furthermore, on lit areas, the floodlights located on the support masts develop significant power, therefore resulting in high electricity consumption. In addition, these floodlights often generate significant light pollution, providing lighting around the pitch that may not be desired.
Pour éviter la dépense importante liée à l'installation de projecteurs portés par des mâts, certains terrains de tennis sont éclairés par des rampes de tubes fluorescents s'étendant le long des terrains, pouvant être portés par les poteaux de clôture du terrain ou par une structure dédiée, comme dans le document

La présente invention a pour objectif de pallier ces inconvénients de l'art antérieur.The present invention aims to overcome these drawbacks of the prior art.
Plus particulièrement, la présente invention a pour objectif de fournir un dispositif d'éclairage d'un terrain, et plus particulièrement d'un terrain de sport, qui nécessite un coût d'installation réduit par rapport aux solutions d'éclairage généralement utilisées.More particularly, the present invention aims to provide a device for lighting a field, and more particularly a sports field, which requires a reduced installation cost compared to the lighting solutions generally used.
Un autre objectif de l'invention est de fournir un tel dispositif d'éclairage qui offre une grande homogénéité de l'éclairage, répondant ainsi à des contraintes normatives exigeantes.Another objective of the invention is to provide such a lighting device which offers great homogeneity of lighting, thus meeting demanding normative constraints.
Un autre objectif de l'invention est de fournir un tel dispositif d'éclairage dont l'installation et les réglages sont simplifiés par rapport aux solutions de l'art antérieur.Another objective of the invention is to provide such a lighting device whose installation and adjustments are simplified compared to the solutions of the prior art.
Encore un autre objectif de l'invention est de fournir un tel dispositif d'éclairage qui soit bien adapté à la pratique du sport concerné, et en particulier qui limite au maximum les risques d'éblouissement ou d'éclat de lumière des athlètes ou des joueurs, et qui limite les ombres portées sur le terrain.Yet another objective of the invention is to provide such a lighting device which is well suited to the practice of the sport concerned, and in particular which limits as much as possible the risks of dazzling or flashing of light of athletes or athletes. players, and which limits the shadows cast on the field.
Ces objectifs, ainsi que d'autres qui apparaîtront plus clairement par la suite, sont atteints à l'aide d'une clôture pour entourer la surface d'un terrain présentant une aire de jeu, selon la revendication 1, qui porte un dispositif d'éclairage de ce terrain.These objectives, as well as others which will appear more clearly later, are achieved using a fence to surround the surface of a field having a playing area, according to
Dans la présente demande on pourra considérer que la rampe s'étend horizontalement si elle présente un angle inférieur à 5° avec l'horizontale. De même, on pourra considérer que le faisceau est orienté perpendiculairement à la direction longitudinale de la rampe s'il présente un angle inférieur à 5° avec la perpendiculaire. Par ailleurs, conformément aux usages dans le domaine de l'éclairage, l'angle de diffusion d'un faisceau lumineux est considéré comme l'angle de diffusion de la largeur à mi-hauteur (largeur du faisceau dans lequel l'intensité lumineuse est au moins égale à l'intensité maximum, plus couramment désignée par l'expression anglaise « full widi-h of half maximum » ou par l'acronyme FWHM) du faisceau.In the present application we can consider that the ramp extends horizontally if it has an angle less than 5° with the horizontal. Likewise, we can consider that the beam is oriented perpendicular to the longitudinal direction of the ramp if it has an angle less than 5° with the perpendicular. Furthermore, in accordance with usage in the field of lighting, the diffusion angle of a light beam is considered to be the diffusion angle of the width at half height (width of the beam in which the light intensity is at least equal to the maximum intensity, more commonly designated by the English expression “ full width of half maximum ” or by the acronym FWHM) of the beam.
Un tel dispositif présentant une rampe de sources lumineuses très directives orientées parallèlement les unes aux autres permet d'éclairer efficacement un terrain, même quand la rampe est placée à faible hauteur, sans générer d'éblouissement des personnes placées sur ce terrain, si elles ne sont pas tournées vers la rampe. Ce dispositif est donc très adapté à l'éclairage de terrains de sport, particulièrement des terrains dédiés à la pratique de sports dans lesquels les joueurs ou athlètes sont principalement orientés selon une direction préférentielle. Dans ce dernier cas, la ou les rampes d'éclairage peuvent préférentiellement être parallèles à cette direction préférentielle.Such a device presenting a ramp of very directive light sources oriented parallel to each other makes it possible to effectively illuminate a site, even when the ramp is placed at a low height, without generating dazzling of people placed on this site, if they do not are not facing the ramp. This device is therefore very suitable for lighting sports fields, particularly fields dedicated to the practice of sports in which the players or athletes are mainly oriented in a preferential direction. In the latter case, the lighting strip(s) may preferably be parallel to this preferred direction.
De façon avantageuse, la rampe, ou au moins une des rampes, peut être placée à une hauteur prédéfinie par rapport audit terrain. Cette hauteur peut par exemple être prédéfinie quand les terrains présentent des dimensions normalisées, et que la rampe peut être fixée à un élément du terrain, comme les clôtures du terrain.Advantageously, the ramp, or at least one of the ramps, can be placed at a predefined height relative to said terrain. This height can for example be predefined when the grounds have standardized dimensions, and the ramp can be fixed to an element of the land, such as the fences of the land.
Avantageusement, cette hauteur de la rampe est relativement faible, par rapport aux dimensions du terrain à éclairer, de telle sorte que les faisceaux des sources lumineuses sont préférentiellement orientés selon des directions présentant des angles de moins de 25° avec l'horizontale. L'éclairage rasant du terrain ainsi produit permet d'éviter l'éblouissement des joueurs et de limiter la consommation d'énergie.Advantageously, this height of the ramp is relatively low, compared to the dimensions of the land to be illuminated, such that the beams of the light sources are preferentially oriented in directions having angles of less than 25° with the horizontal. The ground-level lighting thus produced helps avoid dazzling players and limits energy consumption.
De préférence, la rampe s'étend sur la plus grande partie de la longueur dudit côté du terrain. Cette disposition permet que la rampe puisse éclairer efficacement toute la portion utile du terrain.Preferably, the ramp extends over most of the length of said side of the land. This arrangement allows the ramp to effectively illuminate the entire useful portion of the land.
De préférence, le dispositif comprend au moins deux rampes d'éclairage, se faisant face le long de deux côtés opposés parallèles dudit terrain. Ces deux lampes d'éclairage permettent notamment d'obtenir une meilleure homogénéité de l'éclairage et de limiter les ombres portées.Preferably, the device comprises at least two lighting strips, facing each other along two opposite parallel sides of said terrain. These two lighting lamps make it possible to obtain better homogeneity of lighting and to limit cast shadows.
Selon un mode de réalisation préférentiel, l'orientation desdites sources lumineuses par rapport à ladite ou auxdites rampes est invariable. Cette solution, qui peut être mise en oeuvre pour l'éclairage des terrains présentant des dimensions prédéfinies, simplifie l'installation du dispositif, les orientation des sources lumineuses étant ajustées d'avance et n'étant pas prévues pour être modifiées pendant ou après l'installation.According to a preferred embodiment, the orientation of said light sources relative to said ramp(s) is invariable. This solution, which can be implemented for lighting grounds with predefined dimensions, simplifies the installation of the device, the orientation of the light sources being adjusted in advance and not being intended to be modified during or after the 'facility.
De préférence, la position de ladite ou desdites rampes par rapport au terrain est prédéterminée en fonction des dimensions dudit terrain et des caractéristiques de l'éclairage souhaité.Preferably, the position of said ramp(s) relative to the terrain is predetermined as a function of the dimensions of said terrain and the characteristics of the desired lighting.
Avantageusement, ladite ou au moins une desdites rampes présente des moyens de fixation à des poteaux situés le long dudit côté du terrain. Les rampes peuvent ainsi être assemblées facilement à des éléments préexistant sur le terrain.Advantageously, said or at least one of said ramps has means for fixing to posts located along said side of the land. The ramps can thus be easily assembled to pre-existing elements on the ground.
Selon un mode de réalisation préférentiel, lesdits moyens de fixation comprennent des rails, s'étendant sur toute la longueur de ladite rampe, aptes à maintenir un élément de fixation en un point quelconque de la longueur de ladite rampe. Ces moyens de fixation permettent ainsi une fixation facile des rampes à des poteaux, indépendamment de la position ou de l'écartement de ces poteaux.According to a preferred embodiment, said fixing means comprise rails, extending over the entire length of said ramp, capable of holding a fixing element at any point along the length of said ramp. These fixing means thus allow easy fixing of the ramps to posts, regardless of the position or the spacing of these posts.
De préférence, ladite ou au moins une desdites rampes est composée de plusieurs segments de rampe indépendants, assemblés les uns aux autres.Preferably, said or at least one of said ramps is composed of several independent ramp segments, assembled together.
Dans ce cas, avantageusement, lesdits segments de rampe sont assemblés par des éléments de fixation maintenus par lesdits rails de chacun desdits segments de rampe.In this case, advantageously, said ramp segments are assembled by fixing elements held by said rails of each of said ramp segments.
Selon un mode de réalisation avantageux, les sources lumineuses de ladite ou au moins une desdites rampes sont orientées selon au moins deux directions distinctes. Ces différentes orientations des lampes permettent d'assurer une bonne répartition de la lumière sur le terrain.According to an advantageous embodiment, the light sources of said or at least one of said ramps are oriented in at least two directions distinct. These different orientations of the lamps ensure good distribution of light on the ground.
Avantageusement, ladite ou au moins une desdites rampes présente au moins deux supports distincts aptes à recevoir chacun des sources lumineuses orientées parallèlement selon une direction prédéterminée.Advantageously, said or at least one of said ramps has at least two distinct supports each capable of receiving light sources oriented parallel in a predetermined direction.
De préférence, chacun desdits supports s'étend sur toute la longueur de ladite ou au moins une desdites rampes. Les sources lumineuses peuvent ainsi être réparties selon plusieurs orientations sur toute la longueur de la rampe.Preferably, each of said supports extends over the entire length of said or at least one of said ramps. The light sources can thus be distributed in several orientations over the entire length of the ramp.
Selon un mode de réalisation préférentiel, ladite rampe ou au moins l'une desdites rampes comporte un profilé métallique comprenant lesdits moyens de fixation et au moins une surface plane formant un support apte à recevoir des sources lumineuses orientées parallèlement selon une direction prédéterminée. Un tel profilé métallique possède de bonnes caractéristiques mécaniques. Il peut par ailleurs participer efficacement à la dispersion de la chaleur émise par les sources lumineuses.According to a preferred embodiment, said ramp or at least one of said ramps comprises a metal profile comprising said fixing means and at least one flat surface forming a support capable of receiving light sources oriented parallel in a predetermined direction. Such a metal profile has good mechanical characteristics. It can also participate effectively in the dispersion of the heat emitted by light sources.
Selon un mode de réalisation avantageux, le dispositif comprend au moins deux rampes d'éclairage s'étendant sensiblement parallèlement l'une à l'autre le long d'un même côté dudit terrain, les sources lumineuses d'au moins deux desdites rampes étant orientées selon des directions distinctes, perpendiculaires à la direction longitudinale desdites rampes. Des rampes d'éclairage secondaires peuvent ainsi assurer, sur certaines parties du terrain, l'éclairage de volumes utiles pour la pratique du sport concerné.According to an advantageous embodiment, the device comprises at least two lighting strips extending substantially parallel to each other along the same side of said ground, the light sources of at least two of said strips being oriented in distinct directions, perpendicular to the longitudinal direction of said ramps. Secondary lighting strips can thus ensure, on certain parts of the field, the lighting of useful volumes for the practice of the sport concerned.
Avantageusement, lesdites sources lumineuses sont des lampes comprenant des diodes électroluminescentes.Advantageously, said light sources are lamps comprising light-emitting diodes.
Avantageusement, une rampe d'éclairage, apte à être mise en oeuvre dans un dispositif d'éclairage tel que décrit ci-dessus, comprend des moyens de fixation aptes à permettre sa fixation à des poteaux, en position horizontale, lesdits moyens de fixation comprenant des rails (417, 418), s'étendant sur toute la longueur de ladite rampe (4), aptes à maintenir un élément de fixation en un point quelconque de la longueur de ladite rampe (4), la rampe d'éclairage comprenant une succession de sources lumineuses réparties sur sa longueur, chacune desdites sources lumineuses projetant un faisceau lumineux présentant un angle de diffusion inférieur à 20°,
orienté perpendiculairement à la direction longitudinale de ladite rampe, une partie desdites sources lumineuses présentant une première orientation non modifiable, par rapport à ladite rampe, et une autre partie desdites sources lumineuses présentant une seconde orientation, distincte de ladite première orientation et non modifiable, par rapport à ladite rampe.Advantageously, a lighting strip, capable of being implemented in a lighting device as described above, comprises fixing means capable of allowing its fixing to posts, in a horizontal position, said fixing means comprising rails (417, 418), extending over the entire length of said ramp (4), capable of holding a fixing element at any point along the length of said ramp (4), the lighting ramp comprising a succession of light sources distributed along its length, each of said light sources projecting a light beam having a diffusion angle less than 20°,
oriented perpendicular to the longitudinal direction of said ramp, a part of said light sources having a first non-modifiable orientation, relative to said ramp, and another part of said light sources having a second orientation, distinct from said first orientation and non-modifiable, for example relation to said ramp.

Ce terrain présente une surface 1, sur laquelle des lignes 11 sont tracées à la peinture blanche. La surface rectangulaire entourée par des lignes 11 constitue l'aire de jeu 10, ou court. L'aire de jeux 10 est séparée en deux par un filet 2 tendu entre deux poteaux verticaux 21 et 22, disposés de part et d'autre de l'aire de jeu 10. Les lignes 11 et le filet 2 définissent l'axe principal 100 du terrain, qui s'étend perpendiculairement au plan défini par le filet 2, en séparant l'aire de jeu 10en deux parts égales.This land has a

Pour se conformer aux normes fixées par les fédérations de tennis, l'aire de jeu présente une longueur de 23,77 mètres et une largeur de 10,97 mètres.The
Au cours de la pratique du tennis, les joueurs se placent des deux côtés du filet 2, généralement dans l'aire de jeu 10 ou derrière les lignes de fond de court 112 et 114, et sont principalement orientés dans une direction sensiblement parallèle à l'axe principal 100 du terrain.During tennis practice, the players are placed on both sides of the net 2, generally in the playing
La surface 1 du terrain présente une forme rectangulaire dont les côtés sont parallèles aux limites de l'aire de jeu 10. Pour se conformer aux normes fixées par les fédérations de tennis, cette surface présente préférentiellement une longueur de 36 mètres et une largeur de 18 mètres. Cette surface 1 est entourée par une clôture 3, constituée par un grillage 35 supporté par des poteaux de clôture 30 (seuls certains de ces poteaux 30 sont numérotés sur les figures) entourant les quatre côtés de la surface 1 du terrain.The

Cet éclairage du terrain par deux rampes 4 placées des deux côtés du terrain permet également de limiter fortement les ombres portées générées par les joueurs sur le terrain, qui peuvent perturber les joueurs ou les spectateurs.This lighting of the field by two
Les rampes d'éclairage principales 4 s'étendent horizontalement le long de la plus grande partie de la longueur des clôtures latérales 31 et 33. Plus précisément, ces rampes d'éclairage principales 4 s'étendent, dans le mode de réalisation présenté, sur une longueur de 30,4 mètres des clôtures latérales 31 et 33, dont la longueur totale est de 36 mètres. Cette longueur permet aux rampes d'éclairage principales 4 de faire face à toute la longueur de l'aire de jeux 10, qui mesure 23,77 mètres.The main lighting strips 4 extend horizontally along most of the length of the
Chaque rampe d'éclairage principale 4 présente une forme longitudinale et est attachée aux poteaux 30, du côté de ces poteaux tournés vers le terrain, à une hauteur de 3 mètres. Les poteaux 30 présentant normalement une hauteur comprise entre 3 mètres et 3,50 mètres, les rampes d'éclairage principales 4 sont donc fixées à proximité de leur extrémité supérieure.Each

Le profilé 41 définit également un boîtier de support des lampes, qui est formé entre deux surfaces contiguës de support de lampes 411 et 412 et deux ailes de protection, respectivement une aile inférieure 413 et une aile supérieure 414. Ces deux ailes s'étendent, respectivement, à partir d'un bord des surfaces de support de lampes, respectivement 411 et 412, sensiblement perpendiculairement à ces parois. Les extrémités libres de ces ailes 413 et 414 présentent des rainures, respectivement 4131 et 4141, permettant de maintenir une paroi translucide 44, en polycarbonate, venant fermer le boîtier de support des lampes (sur la
Des lampes, de préférence selon la technologie LED (acronyme de l'anglais « Light-Emitting Diode » signifiant « diode électroluminescente »), sont placées dans le boîtier ainsi formé, en plusieurs points de la rampe d'éclairage principale 4. Certaines de ces lampes, appelées « lampes d'éclairage lointain » 42, sont fixées sur la surface de support 411. Les autres lampes, appelées « lampes d'éclairage proche » 43, sont fixées sur la surface de support 412.Lamps, preferably using LED technology (acronym for “ Light-Emitting Diode ” meaning “light-emitting diode”), are placed in the housing thus formed, at several points of the
De façon avantageuse, ces lampes 42 et 43 sont collées aux surfaces de support 411 et 412 par des moyens permettant un transfert de chaleur entre les lampes et le profilé 41. Le profilé 41, qui est préférentiellement métallique, peut ainsi participer efficacement à la dispersion de la chaleur produite par les lampes.Advantageously, these
Dans le mode de réalisation représenté, les lampes d'éclairage lointain 42 et les lampes d'éclairage proche 43 sont identiques. Elles peuvent cependant être différentes dans d'autres modes de réalisation. Ces lampes 42 et 43 sont constituées par une carte électronique, respectivement 421 et 431, dont une surface plane est destinée à être collée sur un support et dont l'autre surface présente une diode électroluminescente (non visible sur les figures) recouverte par un bloc optique, respectivement 422 et 432. Ces blocs optiques 422 et 432 agissent comme une lentille concentrant la lumière émise par les diodes en un faisceau lumineux.In the embodiment shown, the
Selon un mode de réalisation particulier, non représenté par les figures, une partie du boîtier de support des lampes peut être recouvert de résine, afin de protéger les lampes de la poussière et de l'eau. Dans ce cas, la résine recouvre la base de chacune des lampes, et notamment la carte électronique 421 ou 431, et la base du bloc optique 422 ou 432. En revanche, la portion du bloc optique émettant le faisceau lumineux n'est pas couvert de résine. Dans ce mode de réalisation particulier, il n'est pas nécessaire de fermer le boîtier de support des lampes avec la paroi translucide 44, les lampes étant suffisamment protégées par la résine.According to a particular embodiment, not shown in the figures, part of the lamp support housing can be covered with resin, in order to protect the lamps from dust and water. In this case, the resin covers the base of each of the lamps, and in particular the
Dans le mode de réalisation représenté, les blocs optiques, respectivement 432 et 432, forment un faisceau lumineux conique représentée en pointillés sur la
Les blocs optiques 422 et 432 sont conçus pour diriger les faisceaux, respectivement 429 et 439, selon une direction, respectivement 420 et 430, perpendiculaire à la surface plane des cartes électroniques 421 et 431, et donc perpendiculaire aux surfaces de support, respectivement 411 et 412, du profilé 41. Ces surfaces de support 411 et 412 présentent des orientations choisies, en fonction du terrain à éclairer, des lampes utilisées et de la position de la rampe par rapport au terrain, pour offrir une répartition homogène de la lumière sur le terrain.The
Dans le mode de réalisation représenté, l'orientation des surfaces 411 et 412 est choisie pour le cas d'une rampe comprenant les lampes décrites ci-dessus, placée à 3 mètres de hauteur sur les poteaux de clôture du terrain de tennis à éclairer. La surface 411 présente une orientation telle que le faisceau émis par les lampes d'éclairage lointain 42 soit orienté selon la direction 420, formant un angle β1 égal à 78° avec verticale, quand la rampe 4 est dans sa configuration d'utilisation. La surface 412 présente une orientation telle que le faisceau émis par les lampes d'éclairage proche 43 soit orienté selon la direction 430, formant un angle β2 égal à 66° avec la verticale, quand la rampe 4 est dans sa configuration d'utilisation. Dans tous les cas, les faisceaux sont orientés dans des directions perpendiculaires à la direction longitudinale de la rampe 4, donc perpendiculaires à l'axe principal 100 du terrain.In the embodiment shown, the orientation of the

Les faisceaux produits par les lampes 42 et 43 portées par les rampes 4 ne peuvent donc éblouir un joueur que dans des cas très rares lors de la pratique du tennis.The beams produced by the
Comme le montre la
Dans le mode de réalisation présenté, la rampe 4 présente, sur sa longueur, une lampe 42 ou 43 environ tous les 12 cm, en alternant des séries de deux lampes d'éclairage proche 43 et de six lampes d'éclairage lointain 42. Les inventeurs ont déterminé que cette répartition des lampes, avec les caractéristiques, les orientations de lampes et les positions des rampes exposées ci-dessus, permettait d'obtenir une excellente répartition de l'éclairage sur un terrain de tennis extérieur, satisfaisant aux normes fixées par les fédérations de tennis pour l'organisation de compétitions en extérieur. Par ailleurs, cette répartition régulière des lampes permet de générer une ligne d'éclairage quasiment continue tout le long de la rampe 4.In the embodiment presented, the
Il est cependant possible, sans sortir du cadre de l'invention, de mettre en oeuvre une ou plusieurs rampes présentant chacune une ou plusieurs surfaces orientées suivant des angles différents, et portant des lampes présentant des caractéristiques différentes, pour s'adapter à d'autres configurations, par exemple à l'éclairage d'un terrain autre qu'un terrain de tennis extérieur, ou un système d'éclairage dans lequel les rampes seraient placées dans une autre position par rapport au terrain.It is however possible, without departing from the scope of the invention, to implement one or more ramps each having one or more surfaces oriented at different angles, and carrying lamps having different characteristics, to adapt to other configurations, for example to the lighting of a field other than an outdoor tennis court, or a lighting system in which the ramps would be placed in another position relative to on the ground.
Le dispositif d'éclairage représenté comporte, en plus des deux rampes d'éclairage principales 4, quatre rampes d'éclairage secondaires 5 s'étendant parallèlement aux rampes d'éclairage principales 4. Il est à noter que, dans d'autres modes de réalisation de l'invention, le dispositif d'éclairage pourrait ne comporter qu'une rampe, ou une ou deux rampes d'éclairage de chaque côté du terrain, ou au contraire un plus grand nombre de rampes. Dans le mode de réalisation représenté par les figures, deux rampes d'éclairage secondaires 5 sont placées en dessous de chacune des rampes d'éclairage principales 4. Chacune de ces rampes d'éclairage secondaires 5 mesure 1,90 mètres de longueur, et est accrochée centrée sur un des poteaux 30 voisin des poteaux 30 les plus proches du filet 2. Ainsi, de chaque côté du terrain, deux rampes d'éclairage secondaires 5 sont séparées de plusieurs mètres l'une de l'autre, chacune étant placée d'un des côtés du filet 2.The lighting device shown comprises, in addition to the two main lighting strips 4, four
Ces rampes d'éclairage secondaires 5 présentent une structure très proche de celle des rampes d'éclairage principales 4. Elles comportent également des profilés, présentant des rails de fixation et des boîtiers de support des lampes dans lesquels une surface de support de lampes, ou plusieurs surfaces présentant des orientations différentes, sont prévues pour supporter les lampes.These
Dans le mode de réalisation représenté, les rampes d'éclairage secondaires 5 sont constituées à partir du même profilé 41 que les rampes d'éclairage principales 4. Ce profilé est cependant placé dans une position inverse, l'aile 413 étant placée vers le haut et l'aile 414 étant placée vers le bas. Les surfaces de support de lampes de ce profilé présentent en conséquence des orientations différentes.In the embodiment shown, the secondary lighting strips 5 are made from the
Dans ce mode de réalisation, seule la surface 411 du profilé 41 constituant chaque rampe d'éclairage secondaire 5 porte des lampes. Ces lampes émettent donc un faisceau 50 orienté selon une direction perpendiculaire à la direction principale du terrain et formant un angle de 102° par rapport à la verticale. Les lampes utilisées dans ce mode de réalisation présentent un angle de diffusion de 30°, très supérieur à l'angle de diffusion des lampes mises en oeuvre dans les rampes d'éclairage principal 4. Elles peuvent cependant, dans d'autres modes de réalisation, présenter des caractéristiques différentes.In this embodiment, only the
Le faisceau 50, qui est représenté sur la
Le dispositif d'éclairage représenté par les figures peut être installé très facilement sur un terrain de tennis.' Chacune des rampes 4 est composée d'une pluralité de segments, qui sont chacun complètement équipés des lampes et de la paroi translucide. À titre d'exemple, chaque rampe 4 est constituée de huit segments de 3,80 mètres chacun. Cette longueur des segments, qui est supérieure à l'écartement généralement constaté entre deux poteaux de clôture 30 successifs, permet que chacun des segments puisse être solidarisé à au moins un des poteaux 30.The lighting device shown in the figures can be installed very easily on a tennis court.' Each of the
Les différents segments formant une même rampe peuvent être assemblés facilement, comme le montre la
Du fait de leur poids relativement faible, les rampes peuvent facilement, une fois assemblées, être levées et fixées aux poteaux de clôture 30, à une hauteur de 3 mètres. La
Le montage mécanique des rampes 4 et 5 peut ainsi être effectué très facilement par un simple assemblage de boulons, sans qu'il y ait besoin de découpage ni de perçage. Il ne nécessite aucune érection de mât, les poteaux de clôture préexistants étant utilisés. Il peut donc être effectué rapidement, et pour un coût très réduit, par des personnes n'ayant pas de qualifications particulières.The mechanical assembly of
Chacune des sections de la rampe 4 comporte un ensemble de fils électriques, non représentés sur les figures, permettant l'alimentation de chacune des lampes. Selon une caractéristique avantageuse, chaque segment de la rampe 4 présente, à chacune de ses extrémité, un connecteur d'alimentation unique, qui peut être branché au connecteur correspondant de la section adjacente. Les fils d'alimentation électrique de chacune des sections peuvent donc être assemblés les uns aux autres très facilement.Each of the sections of the
À une extrémité de chacune des rampes 4 et 5, le connecteur d'alimentation peut être branché à un câble d'alimentation, permettant de fournir l'énergie électrique générée par un boîtier d'alimentation qui peut être placé au pied de la clôture 3. Un tel boîtier électrique, permettant d'alimenter l'ensemble des lampes d'une ou de plusieurs rampes 4 ou 5, peut-être branché sur le réseau électrique standard. En effet, l'éclairage du terrain par des lampes à LED très directives et situées à faible distance du terrain à éclairer consomme relativement peu d'énergie. L'énergie consommée est, notamment, très inférieure à l'énergie consommée par des projecteurs placés en haut de mâts, du fait de la faible distance entre les sources lumineuses et la surface à éclairer.At one end of each of the
A chaque extrémité des rampes, un capot de fermeture ou un flasque peut être assemblé pour fermer le boîtier de support des lampes. Ce capot ou ce flasque peut avantageusement être fixé par des vis s'insérant dans les trous 415 et 416, prévus à cet effet dans le profilé 41.At each end of the ramps, a closing cover or a flange can be assembled to close the lamp support box. This cover or this flange can advantageously be fixed by screws inserting into the
De façon particulièrement avantageuse, le dispositif d'éclairage selon l'invention ne nécessite aucun réglage, après son installation. Ainsi, dans le mode de réalisation représenté, si les rampes sont placées à la position préconisée par le fabricant (3 mètres de hauteur sur les clôtures latérales du terrain de tennis, pour les rampes d'éclairage principales 4) et que le terrain de tennis à éclairer présente les dimensions recommandées par les fédérations de tennis, l'orientation des différentes lampes sera, sans aucun réglage, directement adapté pour éclairer le terrain de façon optimale. Dans le mode de réalisation décrit ci-dessus, la constitution des rampes empêche d'ailleurs tout réglage de l'orientation des lampes. L'installation du dispositif d'éclairage est donc particulièrement simple.Particularly advantageously, the lighting device according to the invention does not require any adjustment after its installation. Thus, in the embodiment shown, if the ramps are placed in the position recommended by the manufacturer (3 meters in height on the side fences of the tennis court, for the main lighting ramps 4) and the tennis court to be illuminated has the dimensions recommended by the tennis federations, the orientation of the different lamps will be, without any adjustment, directly adapted to illuminate the court optimally. In the embodiment described above, the constitution of the ramps also prevents any adjustment of the orientation of the lamps. The installation of the lighting device is therefore particularly simple.
Dans le mode de réalisation décrit ci-dessus, le dispositif d'éclairage est adapté à l'éclairage d'un terrain de tennis. Bien évidemment, d'autres dispositifs d'éclairage selon l'invention peuvent être facilement mis en oeuvre pour éclairer d'autres types de terrains rectangulaires, par exemple les terrains dédiés à la pratique d'autres sports. La mise en oeuvre de l'invention sur d'autres terrains présentera un avantage particulier quand ces terrains présenteront des dimensions normalisées, permettant aux fabricants de proposer des dispositifs s'adaptant, sans réglage, à l'éclairage des terrains.In the embodiment described above, the lighting device is suitable for lighting a tennis court. Obviously, other lighting devices according to the invention can be easily implemented to illuminate other types of rectangular grounds, for example fields dedicated to the practice of other sports. The implementation of the invention on other grounds will present a particular advantage when these grounds have standardized dimensions, allowing manufacturers to offer devices which adapt, without adjustment, to the lighting of the grounds.
L'utilisation de lampes très directives orientées perpendiculairement à l'axe principal du terrain présentera également un avantage particulier pour l'éclairage des terrains sur lesquels les athlètes ou les joueurs sont orientés principalement selon l'axe principal du terrain, et ne souhaitent pas être éblouis par les éclairages.
L'homme du métier trouvera facilement, sans sortir du cadre de l'invention, des variantes des solutions présentées dans les modes de réalisation ci-dessus, par exemple pour la fixation des rampes aux poteaux ou des segments de rampe entre eux, pour la mise en place des lampes dans les rampes dans les positions angulaires choisies, etc.The use of very directive lamps oriented perpendicular to the main axis of the field will also present a particular advantage for the lighting of fields on which the athletes or players are oriented mainly according to the main axis of the field, and do not wish to be dazzled by the lights.
Those skilled in the art will easily find, without departing from the scope of the invention, variants of the solutions presented in the above embodiments, for example for fixing the ramps to the posts or the ramp segments between them, for the installation of the lamps in the ramps in the chosen angular positions, etc.
