Description détailléedetailed description
Dans la description qui va suivre, les notions de position relative exprimées par des termes tels que « avant », « arrière », « côte-à-côte », « haut », « bas » sont à comprendre par rapport à une direction principale d’éclairage qui est généralement perpendiculaire à la face de sortie du module de signalisation lumineuse, matérialisée par le masque, et une orientation telle qu’illustrée aux figures.In the following description, the notions of relative position expressed by terms such as "front", "rear", "side-to-side", "up", "down" are to be understood in relation to a main direction lighting which is generally perpendicular to the output face of the light signaling module, materialized by the mask, and an orientation as illustrated in the figures.
La est une vue de face d’un module de signalisation lumineuse selon l’invention.There is a front view of a light signaling module according to the invention.
Le module de signalisation 2 comprend un masque 4 et un dispositif de production lumineuse 6 couplé audit masque 4. Le masque 4 comprend une paroi 4.1 généralement étendue, pouvant être plane, et des ajours 4.2 formés dans la paroi 4.1. Les ajours forment un motif, en l’occurrence en forme de triangle. Les ajours 4.2 sont adjacents de proche en proche suivant une direction d’agencement 5. Aussi, le motif des ajours 4.2 s’inverse successivement le long de la direction d’agencement 5, à savoir que la base du triangle passe successivement d’une position haute à une position basse et vice versa le long de la direction d’agencement 5 et de proche en proche. Cette inversion correspond en l’occurrence à une rotation de 180° du motif en triangle. Cet agencement permet aux ajours d’être très proches les uns des autres en ne laissant qu’une mince portion de paroi 4.1 du masque entre chaque paire d’ajours adjacents. En éclairant chaque ajour 4.2 avec le dispositif de production lumineuse 6, le module de signalisation 2 présente alors une surface équivalente éclairée importante par rapport à sa surface extérieure totale, pouvant correspondre à au moins 70% de cette surface extérieure totale.The signaling module 2 comprises a mask 4 and a light-producing device 6 coupled to said mask 4. The mask 4 comprises a generally extended wall 4.1, which may be planar, and openings 4.2 formed in the wall 4.1. The openings form a pattern, in this case in the shape of a triangle. The openings 4.2 are adjacent step by step along an arrangement direction 5. Also, the pattern of the openings 4.2 is successively reversed along the direction of arrangement 5, namely that the base of the triangle passes successively from one high position to a low position and vice versa along the direction of arrangement 5 and step by step. This inversion corresponds in this case to a 180° rotation of the triangle pattern. This arrangement allows the openings to be very close to each other, leaving only a thin wall portion 4.1 of the mask between each pair of adjacent openings. By illuminating each opening 4.2 with the light-producing device 6, the signaling module 2 then has a large illuminated equivalent surface with respect to its total exterior surface, which may correspond to at least 70% of this total exterior surface.
Le dispositif de production lumineuse 6 comprend des surfaces réfléchissantes 8.1 et 8.2 disposées, respectivement, en face des ajours 4.2 et des sources lumineuses 10.1 et 10.2 ( ) associées, respectivement, aux surfaces réfléchissantes en question. En d’autres termes, le dispositif de production lumineuse 6 comprend pour chaque ajour 4.2 une surface réfléchissante disposée en face de l’ajour, et une source lumineuse associée à la surface réfléchissante, c’est-à-dire positionnée par rapport à la surface réfléchissante de manière à l’éclairer et à ce que celle-ci réfléchisse ses rayons lumineux en un faisceau lumineux dirigé vers l’ajour 4.2. Les sources lumineuses 10.1 et 10.2 ( ) sont disposées sur une support commun 12, du type PCB (acronyme de l’expression anglaise « Printed Circuit Board »).The light-producing device 6 comprises reflective surfaces 8.1 and 8.2 arranged, respectively, opposite the openings 4.2 and the light sources 10.1 and 10.2 ( ) associated, respectively, with the reflective surfaces in question. In other words, the light-producing device 6 comprises, for each opening 4.2, a reflecting surface arranged opposite the opening, and a light source associated with the reflecting surface, that is to say positioned with respect to the reflective surface so as to illuminate it and so that it reflects its light rays into a light beam directed towards the opening 4.2. The light sources 10.1 and 10.2 ( ) are arranged on a common support 12, of the PCB type (acronym for the English expression “Printed Circuit Board”).
Parmi les surfaces réfléchissantes 8.1 et 8.2, une sur deux forment des premières surfaces réfléchissantes 8.1, les autres formant alors des deuxièmes surfaces réfléchissantes 8.2. Similairement, les sources lumineuses associées aux premières surfaces réfléchissantes 8.1 forment des premières sources lumineuses 10.1 et les autres sources lumineuses forment des deuxièmes sources lumineuses 10.2. En l’occurrence, les premières surfaces réfléchissantes 8.1 sont disposées en face des ajours 4.2 dont le motif, en l’occurrence en triangle, présente sa plus grande largeur en bas et les deuxièmes surfaces réfléchissantes 8.2 sont disposées en face des ajours 4.2 dont le motif, en l’occurrence en triangle, présente sa plus grande largeur en haut.Among the reflecting surfaces 8.1 and 8.2, one in two form first reflecting surfaces 8.1, the others then forming second reflecting surfaces 8.2. Similarly, the light sources associated with the first reflective surfaces 8.1 form first light sources 10.1 and the other light sources form second light sources 10.2. In this case, the first reflective surfaces 8.1 are arranged opposite the openings 4.2 whose pattern, in this case a triangle, has its greatest width at the bottom and the second reflecting surfaces 8.2 are arranged opposite the openings 4.2 whose motif, in this case a triangle, has its greatest width at the top.
A la , un seul dispositif de production lumineuse 6 est illustré, étant entendu que plusieurs autres dispositifs de production lumineuse, similaires à celui qui est illustré, sont disposés sous le dispositif de production lumineuse 6 illustré et en face des ajours 4.1 situés sous les ajours de la rangée supérieure sur laquelle la direction d’agencement 5 est représentée. A cet effet, il est intéressant de noter que les ajours 4.2 sont également adjacents de proche en proche suivant une autre direction d’agencement 7, transversale à la direction d’agencement 5, avec une inversion successive du motif, permettant au support commun 12 d’être mutualisée par le deuxième dispositif de production lumineuse prévu (et non représenté) pour la deuxième rangée horizontale de motifs. Les sources lumineuses (non visibles) de ce deuxième dispositif de production lumineuse (non représenté) sont alors disposées sur une face du support commun 12, opposée à la face sur laquelle sont disposées les première et deuxième sources lumineuses 10.1 du dispositif de production lumineuse 6.To the , a single light-producing device 6 is illustrated, it being understood that several other light-producing devices, similar to the one illustrated, are arranged under the illustrated light-producing device 6 and opposite the openings 4.1 located under the openings of the upper row on which the direction of arrangement 5 is represented. To this end, it is interesting to note that the openings 4.2 are also adjacent from close to close along another direction of arrangement 7, transverse to the direction of arrangement 5, with a successive inversion of the pattern, allowing the common support 12 to be pooled by the second light-producing device provided (and not shown) for the second horizontal row of patterns. The light sources (not visible) of this second light production device (not shown) are then arranged on one face of the common support 12, opposite to the face on which the first and second light sources 10.1 of the light production device 6 are arranged. .
Les figures 2 à 4 illustrent en perspective le dispositif de production lumineuse 6. A la , le dispositif de production lumineuse 6 est complet alors qu’à la , la pièce optique arrière est absente. La est une vue en coupe parallèle au support commun 12.Figures 2 to 4 illustrate in perspective the light production device 6. At the , the light production device 6 is complete whereas at the , the rear optical part is missing. There is a sectional view parallel to the common support 12.
Le dispositif de production lumineuse 6 comprend une pièce optique avant 14, dite première pièce optique 14, et une pièce optique arrière 16, dite deuxième pièce optique. Les premières surfaces réfléchissantes 8.1 sont formées sur la première pièce optique 14 et les deuxièmes surfaces réfléchissantes 8.2 sont formées sur la deuxième pièce optique 16.The light-producing device 6 comprises a front optical part 14, called the first optical part 14, and a rear optical part 16, called the second optical part. The first reflective surfaces 8.1 are formed on the first optical part 14 and the second reflective surfaces 8.2 are formed on the second optical part 16.
Plus spécifiquement, la première pièce optique 14 comprend une base 14.1 prenant appui sur le support commun 12, des parois arrière courbes 14.2 formant sur leurs faces avant les premières surfaces réfléchissantes 8.1, et des premières parois longitudinales 14.3 s’étendant depuis les parois arrière courbes 14.2 vers l’avant. Chaque paire de premières parois longitudinales 14.3 associées à une paroi arrière courbe 14.2 forme ainsi un premier passage 14.4 pour les rayons lumineux réfléchis par la première surface réfléchissante 8.1 sur ladite paroi arrière courbe 14.2, en direction de l’ajour correspondant formé dans le masque. Les faces internes des premières parois longitudinales 14.3, c’est-à-dire dirigées vers le premier passage 14.4, peuvent être réfléchissantes ou non réfléchissantes.More specifically, the first optical part 14 comprises a base 14.1 resting on the common support 12, curved rear walls 14.2 forming on their front faces the first reflective surfaces 8.1, and first longitudinal walls 14.3 extending from the curved rear walls 14.2 forward. Each pair of first longitudinal walls 14.3 associated with a curved rear wall 14.2 thus forms a first passage 14.4 for the light rays reflected by the first reflecting surface 8.1 on said curved rear wall 14.2, in the direction of the corresponding opening formed in the mask. The internal faces of the first longitudinal walls 14.3, that is to say directed towards the first passage 14.4, can be reflective or non-reflective.
La deuxième pièce optique 16 comprend une base 16.1 recouvrant la première pièce optique 14, des parois arrière courbes 16.2 formant sur leurs faces avant les deuxièmes surfaces réfléchissantes 8.2, et au moins une deuxième paroi longitudinale 16.3 ( ) s’étendant depuis des parois arrière courbes 16.2 vers l’avant. Chaque paire de premières parois longitudinales 14.3 adjacentes associées à deux parois arrière courbes 14.2 adjacentes forme ainsi un deuxième passage 16.4 pour les rayons lumineux réfléchis par la deuxième surface réfléchissante 8.2 sur la paroi arrière courbe 16.2, en direction de l’ajour correspondant formé dans le masque.The second optical part 16 comprises a base 16.1 covering the first optical part 14, curved rear walls 16.2 forming on their front faces the second reflective surfaces 8.2, and at least one second longitudinal wall 16.3 ( ) extending from curved rear walls 16.2 forward. Each pair of first adjacent longitudinal walls 14.3 associated with two adjacent curved rear walls 14.2 thus form a second passage 16.4 for the light rays reflected by the second reflective surface 8.2 on the curved rear wall 16.2, in the direction of the corresponding opening formed in the mask.
Les premiers passages 14.4 formés par les paires de premières parois longitudinales 14.3 associées à une paroi arrière courbe 14.2 sont ainsi fermés par le support commun 12, alors que les deuxièmes passages 16.4 formés par les paires de premières parois longitudinales 14.3 adjacentes associées à deux parois arrière courbes 14.2 adjacentes sont fermés par la base 16.1 de la deuxième pièce optique 16.The first passages 14.4 formed by the pairs of first longitudinal walls 14.3 associated with a curved rear wall 14.2 are thus closed by the common support 12, while the second passages 16.4 formed by the pairs of adjacent first longitudinal walls 14.3 associated with two rear walls adjacent curves 14.2 are closed by the base 16.1 of the second optical part 16.
Les deuxièmes surfaces réfléchissantes 8.2 sont ainsi disposées en arrière par rapport aux premières surfaces réfléchissantes 8.1, de manière à pouvoir correctement éclairer les deuxièmes passages 16.4. Les deuxièmes sources lumineuses 10.2 sont aussi disposées en arrière des premières sources lumineuses 10.1 ainsi que des premières surfaces réfléchissantes 8.1. The second reflective surfaces 8.2 are thus arranged behind the first reflective surfaces 8.1, so as to be able to correctly illuminate the second passages 16.4. The second light sources 10.2 are also arranged behind the first light sources 10.1 as well as the first reflective surfaces 8.1.
Les figures 5 et 6 illustrent en perspective les rayons lumineux réfléchis par une des premières surfaces réfléchissantes et une des deuxièmes surfaces réfléchissantes, respectivement. Il est à noter que le dispositif de production lumineuse 6 illustré aux figures 4 et 5 est inversé par rapport aux figures 1 à 3, les premières et deuxièmes sources lumineuses 10.1 et 10.2 étant en effet situées en haut des premières et deuxièmes surfaces réfléchissantes 8.1 et 8.2.FIGS. 5 and 6 illustrate in perspective the light rays reflected by one of the first reflecting surfaces and one of the second reflecting surfaces, respectively. It should be noted that the light-producing device 6 illustrated in FIGS. 4 and 5 is reversed with respect to FIGS. 1 to 3, the first and second light sources 10.1 and 10.2 being in fact located at the top of the first and second reflecting surfaces 8.1 and 8.2.
A la , on peut observer qu’une partie des rayons lumineux émis par la première source lumineuse 10.1 sont dirigés vers la première surface réfléchissante 8.1 associée pour y être réfléchis longitudinalement le long du premier passage 14.4. Une autre partie des rayons lumineux émis par la première source lumineuse 10.1 sont dirigés directement vers la sortie du premier passage 14.4. Une encore autre partie des rayons lumineux émis par la première source lumineuse 10.1 sont dirigés directement vers les premières parois longitudinales 14.3, en l’occurrence vers leurs faces intérieures par rapport au premier passage 14.4. Lorsque celles-ci sont réfléchissantes, elles participent à leur réflexion vers la sortie du premier passage 14.4. To the , it can be observed that part of the light rays emitted by the first light source 10.1 are directed towards the associated first reflective surface 8.1 to be reflected there longitudinally along the first passage 14.4. Another part of the light rays emitted by the first light source 10.1 are directed directly towards the output of the first passage 14.4. Yet another part of the light rays emitted by the first light source 10.1 are directed directly towards the first longitudinal walls 14.3, in this case towards their inner faces with respect to the first passage 14.4. When these are reflective, they participate in their reflection towards the exit of the first passage 14.4.
Les premières parois longitudinales 14.3 s’étendent avantageusement jusqu’au masque (non représenté à la ), de manière à cloisonner les premiers et deuxièmes passages 14.4 et 16.4 et éviter toute fuite de lumière d’un de ces passages vers un autre de ces passages. Les faces avant ou frontales des premières parois longitudinales 14.3 viennent alors en contact ou, à tout le moins, directement en vis-à-vis des minces portions de paroi 4.1 du masque, entre les ajours 4.2 ( ).The first longitudinal walls 14.3 advantageously extend as far as the mask (not shown in ), so as to partition off the first and second passages 14.4 and 16.4 and prevent any leakage of light from one of these passages to another of these passages. The front or front faces of the first longitudinal walls 14.3 then come into contact or, at the very least, directly opposite the thin wall portions 4.1 of the mask, between the openings 4.2 ( ).
A la , on peut observer qu’une majeure partie des rayons lumineux émis par la deuxième source lumineuse 10.2 sont dirigés vers la deuxième surface réfléchissante 8.2 associée pour y être réfléchis longitudinalement le long du deuxième passage 16.4. Le fait que la deuxième surface réfléchissante 8.2 soit en arrière des premières surfaces réfléchissantes 8.1 permet de collecter davantage de rayons lumineux émis par la deuxième source lumineuse 10.2 et aussi de faire passer davantage de rayons lumineux dans le deuxième passage 16.4. La section du deuxième passage 16.4, correspondant au motif, présentant une largeur décroissante vers le haut, c’est-à-dire en direction du côté où se trouve la deuxième source lumineuse 10.2, est en soi défavorable à un passage des rayons lumineux émis directement et aussi réfléchis par la deuxième surface réfléchissante 8.2, car ceux-ci se concentrent dans une partie haute du deuxième passage 16.4 qui, précisément, présente une largeur réduite. Le fait de reculer la deuxième surface réfléchissante 8.2 et la deuxième source lumineuse 10.2 associée, permet aux rayons lumineux en question de converger vers une zone centrale ou avant du deuxième passage 16.4 et ensuite de converger vers la sortie dudit deuxième passage en vue d’un éclairage homogène et comparable en puissance avec celui des premiers passages 14.4. To the , it can be observed that a major part of the light rays emitted by the second light source 10.2 are directed towards the associated second reflective surface 8.2 to be reflected there longitudinally along the second passage 16.4. The fact that the second reflective surface 8.2 is behind the first reflective surfaces 8.1 makes it possible to collect more light rays emitted by the second light source 10.2 and also to pass more light rays through the second passage 16.4. The section of the second passage 16.4, corresponding to the pattern, having a decreasing width upwards, that is to say in the direction of the side where the second light source 10.2 is located, is in itself unfavorable to a passage of the light rays emitted directly and also reflected by the second reflective surface 8.2, because these are concentrated in an upper part of the second passage 16.4 which, precisely, has a reduced width. The fact of moving the second reflective surface 8.2 and the associated second light source 10.2 back, allows the light rays in question to converge towards a central or front zone of the second passage 16.4 and then to converge towards the exit of said second passage for a homogeneous lighting and comparable in power with that of the first passages 14.4.
La face intérieure de la base 16.1 de la deuxième pièce optique 16 peut être réfléchissante ou non-réfléchissante.The inner face of the base 16.1 of the second optical part 16 can be reflective or non-reflective.
A la et plus particulièrement à la , on peut observer une deuxième paroi longitudinale 16.3 formée par la deuxième pièce optique 16. Cette deuxième paroi longitudinale 16.3 s’étend depuis la paroi arrière courbe 16.2 formant la deuxième surface réfléchissante 8.2, plus précisément depuis une jonction de deux parois arrière courbe 16.2 adjacentes, et ce vers l’avant, en l’occurrence vers la paroi arrière courbe 14.1 formant la première surface réfléchissante 8.1. Cette deuxième paroi longitudinale 16.3 permet ainsi de cloisonner la deuxième surface réfléchissante 8.2 et sa deuxième source lumineuse 10.2 associée, de manière à éviter tout passage de lumière d’une des deuxième sources lumineuses 10.2 vers un deuxième passage 16.4 voisin. Ce cloisonnement permet ainsi d’éclairer les ajours de manière individuelle sans fuite de lumière vers un ajour voisin.To the and more particularly to the , one can observe a second longitudinal wall 16.3 formed by the second optical part 16. This second longitudinal wall 16.3 extends from the curved rear wall 16.2 forming the second reflecting surface 8.2, more precisely from a junction of two adjacent curved rear walls 16.2 , and this towards the front, in this case towards the curved rear wall 14.1 forming the first reflective surface 8.1. This second longitudinal wall 16.3 thus makes it possible to partition off the second reflecting surface 8.2 and its associated second light source 10.2, so as to avoid any passage of light from one of the second light sources 10.2 to a second neighboring passage 16.4. This partitioning thus makes it possible to illuminate the openings individually without light leaking towards a neighboring opening.
Le motif de l’exemple de réalisation décrit ci-avant est un triangle, étant toutefois entendu que d’autres formes sont envisageables, comme notamment un trapèze ou toute autre forme présentant une variation de largeur, dans une direction perpendiculaire à la direction d’agencement. Dans le cas du motif en triangle, la base du triangle correspond à une largeur maximale et le sommet opposé correspond à une largeur minimale. Dans le cas du motif en trapèze, la grande base correspond à une largeur maximale et la petite base correspond à une largeur minimale. De nombreuses autres formes géométriques sont envisageables.The pattern of the embodiment described above is a triangle, it being understood, however, that other shapes can be envisaged, such as in particular a trapezium or any other shape having a variation in width, in a direction perpendicular to the direction of layout. In the case of the triangle pattern, the base of the triangle corresponds to a maximum width and the opposite vertex corresponds to a minimum width. In the case of the trapezium pattern, the large base corresponds to a maximum width and the small base corresponds to a minimum width. Many other geometric shapes are possible.
Le motif de l’exemple de réalisation décrit ci-avant est constant. Il est toutefois envisageable de prévoir un motif dont la taille ou du moins certaines dimensions varient le long de la direction d’agencement.The pattern of the embodiment described above is constant. It is however possible to envisage providing a pattern whose size or at least certain dimensions vary along the direction of arrangement.
Le module de signalisation selon l’invention peut être utilisé notamment pour une fonction de signalisation à l’avant d’un véhicule, comme par exemple un DRL (acronyme de « Daytime Running Light ») ou enclore pour une fonction de signalisation à l’arrière d’un véhicule, comme notamment une fonction lanterne ou feux stop.The signaling module according to the invention can be used in particular for a signaling function at the front of a vehicle, such as for example a DRL (acronym for "Daytime Running Light") or enclosed for a signaling function at the rear of a vehicle, such as in particular a lantern or brake light function.
