Description

DISPOSITIF LUMINEUX DE SIGNALISATION, NOTAMMENT DESTINE A ASSURER UN BALISAGE DE SECURITE La présente invention concerne un dispositif lumineux de signalisation, notamment destiné à assurer un balisage de sécurité, tel que, par exemple, celui de voies de circulation. The present invention relates to a luminous signaling device, in particular intended to provide security markings, such as, for example, that of traffic lanes.
Un tel dispositif doit posséder une intensité lumineuse et une visibilité du signal dans l'espace devant répondre à des conditions réglementaires strictes ou à des exigences particulières de l'utilisateur.Such a device must have a light intensity and visibility of the signal in the space which must meet strict regulatory conditions or meet specific requirements of the user.
Les dispositifs connus comprennent des lampes à incandescence ou à décharge, qui présentent les inconvénients d'avoir une consommation électrique importante et surtout un prix d'exploitation élevé compte tenu de la fréquence de remplacement des ampoules et de la maintenance qu'elles requièrent.Known devices include incandescent or discharge lamps, which have the drawbacks of having a high electrical consumption and above all a high operating price taking into account the frequency of replacement of the bulbs and the maintenance which they require.
De plus, la défectuosité de l'ampoule se traduit par une absence complète de signalisation, avec les conséquences dommageables qui peuvent en résulter. L'emploi de diodes électroluminescentes peut être envisagé pour ce type d'application, en particulier dans un dispositif du type de celui décrit dans le brevet français N° 85 15144.In addition, the defect of the bulb results in a complete absence of signaling, with the damaging consequences that may result. The use of light-emitting diodes can be envisaged for this type of application, in particular in a device of the type described in French patent No. 85 15144.
Les avantages d'une telle solution sont ceux inhérant aux diodes électroluminescentes, à savoir faible consommation, fiabilité, et existence d'un signal même en cas de défectuosité d'une ou de plusieurs diodes.The advantages of such a solution are those inherent in light-emitting diodes, namely low consumption, reliability, and existence of a signal even in the event of failure of one or more diodes.
Cependant, l'emploi de diodes présente des limites dans la mesure où le signal qu'elles produisent a une luminosité relativement faible et où l'intensité de ce signal est d'autant plus faible que l'angle d'émission des diodes est grand.However, the use of diodes presents limits insofar as the signal which they produce has a relatively weak luminosity and the intensity of this signal is all the smaller the larger the angle of emission of the diodes. .
Il faudrait dès lors, pour atteindre une luminosité significative dans toutes les directions, envisager de réaliser un circuit circulaire, comportant les diodes, de dimensions importantes, afin que les angles entre les faisceaux des diodes soient faibles et que lesdits faisceaux puissent s'additionner pour l'obtention de l'intensité lumineuse souhaitée dans toutes les directions. Dans l'état actuel des performances des meilleures diodes, produire un signal horizontal homogène de dix candelas sur 360° impliquerait l'emploi de 120 diodes, avec, entre l'axe de deux diodes adjacentes, un angle de 3°, soit un circuit circulaire de 400 mm de diamètre. Or, les supports de dispositifs lumineux et les vérines qui les coiffent ont le plus couramment un diamètre inférieur à 70 mm, ce qui rend un tel circuit complètement inutilisable.It would therefore be necessary, to achieve significant brightness in all directions, to consider making a circular circuit, comprising the diodes, of large dimensions, so that the angles between the beams of the diodes are weak and that said beams can add up to obtain the desired light intensity in all directions. In the current state of performance of the best diodes, producing a homogeneous horizontal signal of ten candelas over 360 ° would imply the use of 120 diodes, with, between the axis of two adjacent diodes, an angle of 3 °, i.e. a circuit circular 400 mm in diameter. However, the supports for light devices and the cylinders which cover them most commonly have a diameter of less than 70 mm, which makes such a circuit completely unusable.
La présente invention vise à remédier à ces inconvénients en fournissant un dispositif apte à répondre aux exigences de la réglementation ou de l'utilisateur, tout en occupant un volume restreint lui permettant notamment d'être intégré aux supports et aux vérines des lampes existantes. A cet effet, le dispositif qu'elle concerne comprend une série de circuits électriques empilés, comprenant des diodes électroluminescentes régulièrement réparties sur au moins une partie de leur périphérie, les diodes d'un circuit étant décalées angulairement par rapport à celles des autres circuits selon une valeur de décalage suffisamment faible pour que plusieurs faisceaux de diodes se recoupent dans toutes les directions souhaitées d'émission, le nombre de circuits étant au moins égal à la valeur de l'angle formé par deux diodes adjacentes d'un circuit divisée par ladite valeur de décalage angulaire.The present invention seeks to remedy these drawbacks by providing a device capable of meeting the requirements of the regulations or of the user, while occupying a limited volume allowing it in particular to be integrated into the supports and cylinders of existing lamps. To this end, the device which it relates to comprises a series of stacked electrical circuits, comprising light-emitting diodes regularly distributed over at least part of their periphery, the diodes of a circuit being angularly offset with respect to those of the other circuits according to a sufficiently small offset value for several diode beams to overlap in all the desired emission directions, the number of circuits being at least equal to the value of the angle formed by two adjacent diodes of a circuit divided by said angular offset value.
Ainsi, le dispositif selon l'invention permet, par l'addition de plusieurs faisceaux de diodes, quelle que soit la position de 1*observateur par rapport au dispositif, d'obtenir l'intensité et la distribution photométrique souhaitées, sous un volume limité qui permet l'installation de ce dispositif sous les vérines usuelles.Thus, the device according to the invention makes it possible, by the addition of several diode beams, whatever the position of the observer relative to the device, to obtain the intensity and the distribution. photometric desired, in a limited volume which allows the installation of this device under the usual cylinders.
Selon une forme préférée de réalisation de l'invention, le dispositif comprend un axe et les circuits précités sont circulaires et imprimés dans des disques supports venant s'engager coaxialement sur ledit axe.According to a preferred embodiment of the invention, the device comprises an axis and the aforementioned circuits are circular and printed in support discs coming to engage coaxially on said axis.
Avantageusement, le positionnement angulaire relatif des disques est réalisé au moyen d'une gorge hélicoïdale aménagée dans ledit axe, selon le pas voulu, et par un téton radial aménagé dans l'ouverture centrale des disques, ce téton étant destiné à être engagé dans ladite gorge hélicoïdale, ou inversement, par un filet hélicoïdal aménagé dans 1'axe et des encoches correspondantes aménagées dans les disques. Pour sa bonne compréhension, l'invention va être à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du dispositif qu'elle concerne. La figure 1 est une vue d'un sous-ensemble qu'il comprend ; la figure 2 est une vue de dessus d'une partie de ce dispositif ; la figure 3 est une vue de côté de ce dispositif et la figure 4 en est une vue selon une variante de réalisation.Advantageously, the relative angular positioning of the discs is achieved by means of a helical groove arranged in said axis, according to the desired pitch, and by a radial stud arranged in the central opening of the discs, this stud being intended to be engaged in said helical groove, or vice versa, by a helical thread arranged in the axis and corresponding notches arranged in the discs. For a good understanding, the invention will be described again below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the device which it concerns. Figure 1 is a view of a sub-assembly it includes; Figure 2 is a top view of part of this device; Figure 3 is a side view of this device and Figure 4 is a view according to an alternative embodiment.
La figure 1 représente un disque 1 en matière électriquement isolante, dans lequel est imprimé un circuit électrique circulaire 2, coaxial au disque 1.FIG. 1 represents a disc 1 of electrically insulating material, in which a circular electrical circuit 2 is printed, coaxial with the disc 1.
Ce dernier a un diamètre maximal inférieur à 70 mm, ce qui lui permet d'être placé sous les vérines usuelles des dispositifs lumineux de signalisation.The latter has a maximum diameter of less than 70 mm, which allows it to be placed under the usual cylinders of light signaling devices.
Le disque 1 comprend dix diodes électroluminescentes 3 régulièrement réparties sur sa périphérie et est percé d'un trou axial 4 dans lequel fait saillie un téton 5, perpendiculaire au plan du disque 1.The disc 1 comprises ten light-emitting diodes 3 regularly distributed over its periphery and is pierced with an axial hole 4 in which protrudes a stud 5, perpendicular to the plane of the disc 1.
La figure 3 montre le dispositif selon l'invention. Celui-ci comprend une tige centrale 6 pourvue d'une gorge hélicoïdale 7, sur laquelle est engagée une pluralité de disques 1, treize dans l'exemple représenté, les tétons 5 des différents disques 1 venant s'engager et coulisser dans la gorge 7.Figure 3 shows the device according to the invention. This comprises a central rod 6 provided with a helical groove 7, on which is engaged a plurality of discs 1, thirteen in the example shown, the pins 5 of the different discs 1 coming to engage and slide in the groove 7 .
Les circuits 2 sont ensuite connectés en parallèle à un circuit principal comprenant une source d'alimentation électrique, à l'aide de moyens de connexion appropriés (non représentés) , tels que, par exemple, des pattes radiales de connexion, venant au contact de fils conducteurs placés le long des parois périphériques des disques 1.The circuits 2 are then connected in parallel to a main circuit comprising an electrical power source, using appropriate connection means (not shown), such as, for example, radial connection lugs, coming into contact with conducting wires placed along the peripheral walls of the discs 1.
Comme cela apparaît sur les figures 2 et 3, 1•engagement des disques 1 sur la tige 6 permet de décaler angulairement les diodes 3 d'un disque 1 par rapport à celles des autres disques, cette valeur de décalage étant constante.As shown in Figures 2 and 3, 1 • engagement of the discs 1 on the rod 6 allows angularly offset the diodes 3 of a disc 1 relative to those of other discs, this offset value being constant.
Le pas de la gorge 7 et le nombre de disques 1 empilés sont déterminés de manière à ce que la valeur de décalage entre les diodes 3 soit suffisamment faible pour que plusieurs faisceaux de diodes 3 se recoupent dans toutes les directions d'émission des faisceaux lumineux, le nombre de disques 1 étant au moins égal à la valeur de l'angle formé par deux diodes 3 adjacentes d'un disque 1 divisée par ladite valeur de décalage.The pitch of the groove 7 and the number of stacked disks 1 are determined so that the offset value between the diodes 3 is sufficiently small so that several beams of diodes 3 overlap in all the directions of emission of the light beams , the number of discs 1 being at least equal to the value of the angle formed by two adjacent diodes 3 of a disc 1 divided by said offset value.
Par exemple, dans la forme de réalisation représentée au dessin, on sait qu'il est nécessaire que la valeur de décalage d'une diode 3 d'un disque 1 par rapport à une autre diode 3 d'un autre disque 1, contigu ou non à ce premier disque, soit de 3° pour obtenir la superposition des faisceaux précités, compte tenu du type des diodes 3 employées. Sachant qu'il est prévu dix diodes 3 par disque 1, soit un angle de 36° entre deux diodes 3, il faudra que le nombre de disques N vérifie la relation NFor example, in the embodiment shown in the drawing, it is known that it is necessary that the offset value of a diode 3 of a disc 1 relative to another diode 3 of another disc 1, contiguous or no to this first disc, or 3 ° to obtain the superposition of the aforementioned beams, taking into account the type of diodes 3 used. Knowing that ten diodes 3 are provided per disc 1, an angle of 36 ° between two diodes 3, the number of disks N must verify the relation N
36 —, ce qui fait au moins douze disques 1.36 -, which makes at least twelve discs 1.
Le dispositif selon l'invention permet, par l'addition de plusieurs faisceaux de diodes 3, quelle que soit la position de l'observateur par rapport au dispositif, d'obtenir l'intensité et la distribution photométrique souhaitées, sous un volume limité qui permet l'installation de ce dispositif sous les vérines usuelles.The device according to the invention makes it possible, by the addition of several diode beams 3, whatever the position of the observer relative to the device, to obtain the desired intensity and photometric distribution, in a limited volume which allows the installation of this device under the usual cylinders.
Ainsi, l'observateur placé en face du dispositif représenté à la figure 3 verra les faisceaux additionnés des diodes 3a,3b,3c des douze disques 1 supérieurs et de la diode 3d du treizième disque 1, le faisceau de cette diode 3d étant parallèle au faisceau de la diode 3a.Thus, the observer placed in front of the device represented in FIG. 3 will see the added beams of diodes 3a, 3b, 3c of the twelve upper discs 1 and of the 3d diode of the thirteenth disc 1, the beam of this 3d diode being parallel to the diode 3a beam.
Il va de soi que l'invention n'est pas limitée à la forme de réalisation qui vient d'en être décrite ci-dessus à titre d'exemple mais qu'elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the embodiment which has just been described above by way of example but that it embraces, on the contrary, all the variant embodiments.
Ainsi, les diodes 3 ne sont pas forcément orientées radialement par rapport au disque 1 comme cela est montré aux figures ; elles peuvent avoir toute orientation angulaire appropriée par rapport au plan du disque 1 ; elles pourraient même être disposées perpendiculairement à ce plan. Notamment, les diodes 3 pourraient n'avoir pas la même orientation angulaire par rapport au plan du circuit 2, tant au sein d'un même disque que d'un disque à l'autre du dispositif.Thus, the diodes 3 are not necessarily oriented radially relative to the disc 1 as shown in the figures; they can have any suitable angular orientation relative to the plane of the disc 1; they could even be arranged perpendicular to this plane. In particular, the diodes 3 could not have the same angular orientation relative to the plane of the circuit 2, both within the same disc as from one disc to the other of the device.
De plus, les angles des diodes 3 par rapport au plan du disque 1 peuvent varier d'un disque à l'autre.In addition, the angles of the diodes 3 relative to the plane of the disc 1 can vary from one disc to another.
Les disques peuvent également n'avoir pas tous le même diamètre au sein d'un même dispositif.The discs may also not all have the same diameter within the same device.
Le système tige 6 à gorge hélicoïdale 7-tétons 5 dans les ouvertures 4 des disques 1 pourrait être remplacé par un système à crans, par une tige filetée et des disques à ouverture taraudée, par des ergots de positionnement angulaire relatif des disques et, d'une manière générale, par tout système permettant de positionner de façon adéquate les disques les uns par rapport aux autres.The rod system 6 with helical groove 7-studs 5 in the openings 4 of the discs 1 could be replaced by a notch system, by a threaded rod and discs with tapped opening, by lugs for relative angular positioning of the discs and, d '' in general, by any system allowing properly position the discs relative to each other.
De plus, comme le montre la figure 4, une enveloppe 9 en verre ou en matériau synthétique transparent peut être prévue pour protéger les diodes 3 et les disques 1, et le circuit reliant les disques 1 à la source d'alimentation électrique peut comporter une douille 8 du type vissable ou à baïonnettes, de sorte que ce dispositif se présente sous l'aspect d'une ampoule existante 10.In addition, as shown in FIG. 4, an envelope 9 made of glass or transparent synthetic material can be provided to protect the diodes 3 and the disks 1, and the circuit connecting the disks 1 to the power supply source can include a socket 8 of the screwable or bayonet type, so that this device is in the form of an existing bulb 10.
Une paroi opaque masquant un secteur d'éclairage peut être prévue, cette paroi pouvant soit être fixe pour limiter l'angle d'éclairage, soit être rotative pour l'obtention d'un effet de clignotement. Avantageusement, cette paroi peut être pourvue d'un revêtement intérieur réfléchissant pour augmenter 1' intensité lumineuse produite par le dispositif.An opaque wall masking a lighting sector can be provided, this wall can either be fixed to limit the lighting angle, or be rotatable to obtain a flashing effect. Advantageously, this wall can be provided with a reflective interior coating to increase the light intensity produced by the device.
L'invention est particulièrement utile dans le domaine du balisage de sécurité et peut avantageusement être associée, compte tenu de sa faible consommation, à des systèmes d'alimentation photovoltaïques et/ou à des accumulateurs. Elle peut aussi être associée à des dispositifs électroniques de régulation, assurant la stabilité de l'intensité lumineuse produite. Enfin, l'invention pourrait s'appliquer à des dispositifs pour lesquels on ne souhaite pas une répartition régulière du signal lumineux. Il suffit alors d'utiliser des disques 1 et des circuits 2 de forme adaptée au signal lumineux à produire (arc de cercle, arc d'ellipse, ... ) . The invention is particularly useful in the field of safety beaconing and can advantageously be associated, given its low consumption, with photovoltaic power systems and / or with accumulators. It can also be associated with electronic regulation devices, ensuring the stability of the light intensity produced. Finally, the invention could be applied to devices for which a regular distribution of the light signal is not desired. It then suffices to use discs 1 and circuits 2 of a shape adapted to the light signal to be produced (circular arc, elliptical arc, etc.).
