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.

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.
