ENSEIGNE LUMINEUSE DOUBLE FACE A DIODES ELECTROLUMINESCENTES CMS DOUBLE-SIDED LIGHT SIGNAL WITH LED LIGHT-EMITTING DIODES
Domaine technique La présente invention concerne le domaine des enseignes lumineuses double face, c'est-à-dire des enseignes lumineuses comportant au moins un motif lumineux qui est visible sur les deux faces de l'enseigne. Elle trouve plus particulièrement son application à la réalisation d'enseignes lumineuses extérieures dites « drapeau », tel que par exemple, mais non exclusivement, les croix de pharmacie.TECHNICAL FIELD The present invention relates to the field of double-sided luminous signs, that is to say luminous signs having at least one luminous pattern which is visible on both sides of the sign. It finds more particularly its application to the realization of outdoor luminous signs called "flag", such as for example, but not exclusively, pharmacy crosses.
Art AntérieurPrevious Art
Les enseignes lumineuses dites « drapeau », du type croix de pharmacie ou équivalent, sont destinées à être fixées sur un support extérieur (mur ou équivalent), en étant orientées perpendiculairement à ce support et en étant positionnées sensiblement dans un plan vertical. Ces enseignes lumineuses comportent des sources lumineuses qui forment au moins un motif lumineux, ledit motif devant être visible sur les deux faces de l'enseigne.The so-called "flag" luminous signs, of the pharmacy cross type or equivalent, are intended to be fixed on an external support (wall or equivalent), being oriented perpendicularly to this support and being positioned substantially in a vertical plane. These luminous signs comprise light sources which form at least one luminous pattern, said pattern to be visible on both sides of the sign.
Pour réaliser ce type d'enseigne lumineuse double face, il est usuel de mettre en œuvre, en guise de sources lumineuses, des tubes néons qui forment le motif visible sur les deux faces de l'enseigne. Une enseigne lumineuse double face à tubes néons, de type croix de pharmacie, est décrite par exemple dans les demandes de brevet français FR 2 765 996 et FR 2 776 810. Les enseignes lumineuses double face à tubes néons présentent les principaux inconvénients suivants.To achieve this type of double-sided light sign, it is usual to implement, as light sources, neon tubes that form the visible pattern on both sides of the sign. A double-sided luminous sign with neon tubes, of the pharmacy cross type, is described, for example, in French patent applications FR 2 765 996 and FR 2 776 810. The double-sided illuminated signs with neon tubes have the following main drawbacks.
Les tubes néons sont relativement lourds et volumineux et constituent de ce fait de manière préjudiciable une limite à la réduction d'épaisseur et à la réduction de poids de l'enseigne lumineuse. Egalement, les tubes néons contiennent des produits toxiques, ce qui complique le recyclage des enseignes. Objectifs de l'inventionNeon tubes are relatively heavy and bulky and therefore detrimental to limit the thickness reduction and weight reduction of the luminous sign. Neon tubes also contain toxic products, which complicates the recycling of signs. Objectives of the invention

Description détailléedetailed description
On a représenté sur les figures 1 à 3 une croix de pharmacie lumineuse, étant rappelé que l'invention ne se limite par à ce type particulier d'enseigne drapeau, mais peut être appliquée pour réaliser tout type d'enseigne lumineuse fine double face comportant au moins un motif lumineux qui est visible sur les deux faces de l'enseigne.FIGS. 1 to 3 show a light pharmacy cross, it being recalled that the invention is not limited to this particular type of flag sign, but may be applied to make any type of double-sided thin light sign comprising at least one light pattern that is visible on both sides of the sign.
En référence aux figures 1 à 3, la croix de pharmacie lumineuse 1 double face comporte un assemblage de plusieurs modules lumineux fins 2,With reference to FIGS. 1 to 3, the double-sided light pharmacy cross 1 comprises an assembly of several fine light modules 2,
2' en forme de croix, qui est représenté seul sur la figure 8 et qui est monté et fixé sur un cadre 3. De préférence, l'enseigne 1 comporte également un capotage 4 de protection transparent ou translucide, à l'intérieur duquel est logé l'assemblage précité de modules 2,2', et qui est de préférence étanche à l'eau. Ce capotage 4 est par exemple en matériau plastique de type plexiglas, ou en verre.2 'cross-shaped, which is shown alone in Figure 8 and which is mounted and fixed on a frame 3. Preferably, the sign 1 also comprises a transparent or translucent protective cover 4, inside which is housed the above assembly of modules 2,2 ', and which is preferably waterproof. This cowling 4 is for example of plastic material of plexiglass type, or glass.
Le cadre 3 est plus particulièrement constitué de plusieurs profilés tubulaire 3a assemblés bout à bout en sorte de former un cadre en forme croix. Ces profilés 3a sont par exemple en plastique ou en métal. En référence aux figures 4 à 7, chaque module lumineux 2 ou 2' comporte une plaque support 20 rigide de très faible épaisseur. Cette plaque support 20 comporte deux faces opposées 20a et 20b dites faces de montage. Sur chacune des deux faces de montage 20a, 20b de la plaque support 20 est monté un ensemble de diodes électroluminescentes CMS (« Composant à Montage de Surface »). Les diodes électroluminescentes CMS montées sur la face de montage 20a sont référencées 21a et les diodes électroluminescentes CMS montées sur la face de montage 20b sont référencées 21b.The frame 3 is more particularly constituted of several tubular sections 3a assembled end to end so as to form a cross-shaped frame. These profiles 3a are for example plastic or metal. With reference to FIGS. 4 to 7, each light module 2 or 2 'comprises a rigid support plate 20 of very small thickness. This support plate 20 has two opposite faces 20a and 20b said mounting faces. On each of the two mounting faces 20a, 20b of the support plate 20 is mounted a set of SMD LEDs ("Surface Mounted Component"). The SMD diodes mounted on the mounting face 20a are referenced 21a and the SMD diodes mounted on the mounting face 20b are referenced 21b.
La structure d'une diode électroluminescente CMS est connue en soi et ne sera donc pas décrite dans le présent texte. Il sera simplement rappelé que ce type de composant électronique peut avantageusement être monté et soudé en surface d'une plaque support sans devoir percer la plaque support. Plus particulièrement, on optera pour des diodes CMS présentant un angle d'émission large, de préférence supérieur à 90°. A titre indicatif et non limitatif de l'invention, on peut par exemple utiliser, comme diodes électroluminescentes CMS 21a et 21b, les diodes qui sont commercialisées par la société Agilent Technologies, sous les références « HSMx-A10x-xxxx PLCC-2 », et dont l'angle d'émission peut avantageusement atteindre 120°.The structure of a light emitting diode CMS is known per se and will therefore not be described in the present text. It will simply be recalled that this type of electronic component can advantageously be mounted and welded to the surface of a support plate without having to pierce the support plate. More particularly, it will opt for SMD diodes having a broad emission angle, preferably greater than 90 °. By way of nonlimiting indication of the invention, it is possible for example to use, as SMD diodes 21a and 21b, the diodes which are sold by Agilent Technologies, under the references "HSMx-A10x-xxxx PLCC-2", and whose emission angle can advantageously reach 120 °.
Chaque diode électroluminescente CMS 21a, 21b est de manière connue en soi, soudée à la surface de Ia face de montage 20a, 21b qui lui correspond, c'est-à-dire à la surface de la face de montage 20a pour les diodes 21a et à la surface de la face de montage 20b pour les diodes 21b.Each SMD diode 21a, 21b is in a known manner welded to the surface of the mounting face 20a, 21b corresponding thereto, that is to say on the surface of the mounting face 20a for the diodes 21a and on the surface of the mounting face 20b for the diodes 21b.
Plus particulièrement, la face de montage 20a (respectivement 20b) de la plaque support 20 comporte un circuit électrique imprimé (non représenté sur les figures) qui permet de connecter les diodes 21a (respectivement 21b) à des moyens d'alimentation électrique et des moyens de commande électronique de l'allumage des diodes. Les diodes 21a (respectivement 21b) sont soudées sur le circuit imprimé de cette face de montage 20a (respectivement 20b). Pour chaque module lumineux 2 ou 2', l'ensemble de diodes 21a respectivement 21b) de la face 20a (respectivement 20b) du support 20 est agencé en sorte de former sur cette face un motif lumineux La (respectivement Lb). Lorsque les diodes des deux faces de montage 20a et 20b sont allumées, elle forment ainsi deux motifs lumineux La et Lb qui sont visibles sur les deux faces du module lumineux 2 ou 2'.More particularly, the mounting face 20a (respectively 20b) of the support plate 20 comprises a printed electrical circuit (not shown in the figures) which makes it possible to connect the diodes 21a (respectively 21b) to power supply means and means electronic control of the ignition of the diodes. The diodes 21a (respectively 21b) are soldered to the printed circuit of this mounting face 20a (respectively 20b). For each light module 2 or 2 ', the set of diodes 21a respectively 21b) of the face 20a (respectively 20b) of the support 20 is arranged so as to form on this face a light pattern La (respectively Lb). When the diodes of the two mounting faces 20a and 20b are lit, they thus form two light patterns La and Lb which are visible on both sides of the light module 2 or 2 '.
Plus particulièrement, les diodes 21a et 21b sont associées par paire en étant montées deux à deux, par exemple en vis-à-vis, de part et d'autre de la plaque support 20. Les motifs lumineux La et Lb des deux faces de montage 20a et 20b du support 20 sont identiques et alignés dans une direction X perpendiculaire au plan des deux faces 20a et 20b du support 20. La structure des modules lumineux 2 et 2' permet avantageusement selon l'invention de réaliser des modules lumineux double face ultra fins et très légers comparativement par exemple à des enseignes à tubes néons. A titre indicatif, et de manière non limitative de l'invention dans un exemple précis de réalisation, on a pu réaliser des modules 2 et 2' présentant une épaisseur e1 de l'ordre de 5,4mm , et montés dans un cadre 3 d'épaisseur e2 de l'ordre de 36mm. Egalement, comparativement à une enseigne lumineuse à tubes néons, la fabrication d'une enseigne lumineuse à base de modules lumineux 2, 2' de l'invention est avantageusement plus simple et plus rapide.More particularly, the diodes 21a and 21b are associated in pairs by being mounted in pairs, for example vis-à-vis, on either side of the support plate 20. The light patterns La and Lb of the two faces of mounting 20a and 20b of the support 20 are identical and aligned in a direction X perpendicular to the plane of the two faces 20a and 20b of the support 20. The structure of the light modules 2 and 2 'advantageously allows, according to the invention, to produce ultra-thin and very light double-sided light modules, for example compared to neon-tube signs. As an indication, and in a nonlimiting manner of the invention in a specific embodiment, it was possible to produce modules 2 and 2 'having a thickness e1 of the order of 5.4 mm, and mounted in a frame 3 d e2 thickness of the order of 36mm. Also, compared to a neon tube light sign, the manufacture of a luminous sign based light modules 2, 2 'of the invention is advantageously simpler and faster.
Comparativement à des enseignes à tubes néons, la mise en oeuvre de diodes électroluminescentes pour réaliser l'enseigne de l'invention permet en outre avantageusement de diminuer la consommation électrique et d'augmenter la durée de vie de l'enseigne. Dans l'exemple particulier de réalisation des figures annexées, les modules 2, 2' de l'enseigne lumineuse 1 sont positionnés les uns par rapport aux autres de telle sorte que leurs plaques support 20 sont adjacentes et alignées dans un même plan d'assemblage P .Compared to signs with neon tubes, the use of light-emitting diodes to achieve the sign of the invention also advantageously reduces the power consumption and increase the life of the sign. In the particular embodiment of the appended figures, the modules 2, 2 'of the luminous sign 1 are positioned relative to each other so that their support plates 20 are adjacent and aligned in the same assembly plane P.
Plus particulièrement, les plaques support 20 d'un module 2 (respectivement module 2') comportent des moyens d'assemblage A (respectivement A') permettant son assemblage avec un module lumineux 2'(respectivement module 2) adjacent.More particularly, the support plates 20 of a module 2 (respectively module 2 ') comprise assembly means A (respectively A') allowing its assembly with a light module 2 '(respectively module 2) adjacent.

En référence au figures 1 et 8, la croix lumineuse 1 comporte un unique module lumineux 2' central, et quatre modules lumineux 2 identiques emboîtés sur la périphérie du module central 2', de telle sorte que les plaques support 20 des modules 2 et 2' forment une croix fine, les plaques 20 des modules 2 formant respectivement les quatre branches de la croix de pharmacie. La juxtaposition des motifs lumineux individuels La, Lb des modules 2 et 2' assemblés permet de former, sur chacune des deux faces 1a et 1b de l'enseigne 1 , un motif lumineux complet représentant notamment une croix lumineuse. Egalement dans l'exemple de réalisation illustré, le module lumineux central 2' de la croix comporte dans son centre un sous ensemble de diodes 21a, 21b qui sont agencées en sorte de permettre l'affichage d'un motif lumineux variable comportant par exemple la date et la température extérieure.With reference to FIGS. 1 and 8, the light cross 1 comprises a single central light module 2 ', and four identical light modules 2 nested on the periphery of the central module 2', so that the support plates 20 of the modules 2 and 2 form a thin cross, the plates 20 of the modules 2 respectively forming the four branches of the pharmacy cross. The juxtaposition of the individual luminous patterns La, Lb of the assembled modules 2 and 2 'makes it possible to form, on each of the two faces 1a and 1b of the sign 1, a complete luminous pattern representing in particular a luminous cross. Also in the exemplary embodiment illustrated, the central light module 2 'of the cross comprises in its center a subset of diodes 21a, 21b which are arranged so as to allow the display of a variable light pattern comprising for example the date and outside temperature.
L'enseigne 1 comporte des moyens d'alimentation électrique et des moyens électroniques de contrôle (carte électronique à microprocesseur) qui permettent de commander, de préférence individuellement, l'allumage des diodes 21a et 21b. Ces moyens sont connectés aux circuits électriques imprimés des deux faces 20a et 20b des plaques support 20, et sont de préférence fixés sur le cadre 3 de l'enseigne, en étant logés à l'intérieur du capotage de protection 4. L'invention peut indifféremment être mise en oeuvre avec tout type de moyen de commande de l'allumage des diodes, lesdits moyens de commande pouvant permettre, par exemple et indifféremment selon l'invention, un allumage permanent des diodes, un allumage clignotant, ou un allumage permettant d'obtenir un affichage dynamique avec défilement.The sign 1 comprises power supply means and electronic control means (microprocessor electronic card) which can control, preferably individually, the ignition of the diodes 21a and 21b. These means are connected to the printed electrical circuits of the two faces 20a and 20b of the support plates 20, and are preferably fixed to the frame 3 of the sign, being housed inside the protective cover 4. The invention may be indifferently be implemented with any type of means for controlling the ignition of the diodes, said control means being able to allow, for example and indifferently according to the invention, a permanent lighting of the diodes, a flashing ignition, or an ignition allowing get a dynamic display with scrolling.
L'invention n'est pas limitée à une enseigne 1 composée de plusieurs modules lumineux 2 ou 2' mais s'étend également à une enseigne lumineuse de faible épaisseur double face constituée d'un unique module lumineux. Par exemple, pour réaliser la croix de pharmacie des figures annexées, les modules 2 et 2' de petite dimension pourraient être remplacés par un unique module de grande dimension. Un avantage lié à la mise en œuvre d'une structure modulaire réside dans la possibilité qui est offerte, en cas de fonctionnement défectueux de l'enseigne, de remplacer le cas échéant uniquement le module lumineux défectueux ; également, la fabrication en série d'enseignes de grande dimension se trouve simplifiée. The invention is not limited to a sign 1 composed of several light modules 2 or 2 'but also extends to a light double-sided light sign consisting of a single light module. For example, to make the cross of pharmacy figures attached, modules 2 and 2 'of small size could be replaced by a single large module. An advantage associated with the implementation of a modular structure lies in the possibility that, in the event of malfunctioning of the sign, it is possible to replace, if need be, only the defective light module; also, mass production of large signs is simplified.
