La présente invention concerne les blocs d'éclairage de sécurité c'est-à-dire des blocs d'éclairage destinés à afficher une signalétique lumineuse dans les établissements recevant du public, aussi bien pour assurer par exemple le balisage des issues d'un tel établissement et/ou celui des services qui y sont proposés, que pour constituer un éclairage de sécurité.The present invention relates to safety lighting blocks, that is to say lighting blocks intended to display a luminous signage in establishments receiving the public, both to ensure for example the marking of the exits of such a device. establishment and / or the services offered therein, only to constitute safety lighting.

L'invention concerne plus particulièrement un bloc d'éclairage de sécurité comprenant :

  • un boîtier support formé d'un socle, ouvert en face avant, adapté à être fixé sur un mur ou un plafond par sa paroi de fond, et d'un couvercle comprenant une face frontale à rapporter en face avant du socle pour former un logement d'accueil pour un circuit d'alimentation électrique et des contacts électriques correspondants, et
  • un panneau lumineux constitué d'au moins une étiquette de signalisation et d'un guide de lumière réunis à leur périphérie par un cadre, ledit guide de lumière étant conçu pour diffuser vers ladite étiquette de signalisation la lumière émise par au moins une source lumineuse disposée le long d'au moins un bord dudit cadre, ledit panneau lumineux étant conçu pour entrer en contact avec lesdits contacts électriques dans un état monté dudit panneau lumineux sur ladite face frontale du couvercle pour l'alimentation électrique de ladite source lumineuse, à la fois dans un premier état de montage dans lequel ledit panneau lumineux est disposé dans un plan parallèle à ladite face frontale et dans un second état de montage dans lequel ledit panneau lumineux est disposé dans un plan perpendiculaire à ladite face frontale.
The invention more particularly relates to a security lighting unit comprising:
  • a support case formed by a base, open on the front face, adapted to be fixed on a wall or a ceiling by its bottom wall, and a cover comprising a front face to be brought to the front face of the base to form a housing; for a power supply circuit and corresponding electrical contacts, and
  • a light panel consisting of at least one signaling label and a light guide joined at their periphery by a frame, said light guide being designed to diffuse towards said signaling tag the light emitted by at least one light source arranged along at least one edge of said frame, said light panel being adapted to contact said electrical contacts in a mounted state of said light panel on said front face of the cover for powering said light source at a time in a first mounting state in which said light panel is disposed in a plane parallel to said front face and in a second mounting state in which said light panel is disposed in a plane perpendicular to said front face.

Un tel bloc d'éclairage est bien connu, notamment par l'exemple qu'en donne le document EP 2 942 770 . Un tel bloc est particulièrement adapté pour permettre son implantation tant sur un mur que sur un plafond, en utilisant avantageusement le même boîtier support pour les deux types d'implantation. Le panneau lumineux est alors assemblé au couvercle du boîtier support selon le premier état de montage, dans le cas de l'implantation du boîtier support sur un mur et selon le second état de montage, dans le cas de l'implantation du boîtier support sur un plafond. Selon le document précité, les premier et second états de montage du panneau lumineux sur le couvercle du boîtier support nécessitent de mettre en oeuvre des moyens de montage par clipsage, d'une part au niveau du panneau et, d'autre part, au niveau du boîtier, qui sont spécifiques et dédiés à chacun des états de montage respectifs du panneau lumineux sur le boîtier support. En particulier, les moyens de montage par clipsage comprennent un premier jeu de pièces détachées spécifique afin de permettre l'assemblage du panneau lumineux au boîtier support dans le premier état de montage et un second jeu de pièces détachées spécifique afin de permettre l'assemblage du panneau lumineux au boîtier support dans le second état de montage. Autrement dit, le technicien en charge de l'installation du bloc doit disposer de plusieurs jeux de pièces détachées spécifiques pour pouvoir s'adapter à différentes configurations d'implantation possibles du bloc, au mur ou au plafond. Une fois le bloc installé dans une configuration d'implantation donnée avec le jeu de pièces détachées correspondant, l'autre jeu de pièces détachées, inutilisé pour le montage, est laissé de côté. La gestion de ces jeux de pièces détachées, qui permettent l'assemblage du panneau lumineux au boîtier support du bloc dans ses différentes configurations d'implantation, entraîne d'une part, un surcoût de production et, d'autre part, des incidences environnementales défavorables, s'agissant du traitement des pièces inutilisées.Such a lighting unit is well known, in particular by the example given in the document EP 2,942,770 . Such a block is particularly adapted to allow its implementation on both a wall and a ceiling, advantageously using the same support case for both types of implantation. The illuminated panel is then assembled to the cover of the support case according to the first mounting state, in the case of the implantation of the support case on a wall and according to the second mounting state, in the case of the implantation of the support case on a ceiling. According to the aforementioned document, the first and second mounting states of the light panel on the cover of the support housing require the use of clipping mounting means, a apart from the panel and, on the other hand, at the housing, which are specific and dedicated to each of the respective mounting states of the light panel on the support housing. In particular, the clipping mounting means comprise a first set of specific spare parts to allow the assembly of the light panel to the support housing in the first mounting state and a second set of specific spare parts to allow assembly of the luminous panel to the support housing in the second mounting state. In other words, the technician in charge of the installation of the block must have several sets of specific spare parts to be able to adapt to different configurations of possible implantation of the block, wall or ceiling. Once the block is installed in a given layout configuration with the corresponding set of spare parts, the other set of spare parts, unused for assembly, is left out. The management of these sets of spare parts, which allow the assembly of the luminous panel to the support box of the block in its various configurations of implantation, entails on the one hand, an additional cost of production and, on the other hand, environmental impacts. unfavorable, as regards the treatment of unused parts.

Dans ce contexte, la présente invention a pour but de proposer un bloc d'éclairage de sécurité exempt des limitations précédemment évoquées et, en particulier, qui permette de mettre en oeuvre les fonctions d'assemblage du panneau lumineux au boîtier support du bloc dans les deux états de montage sans avoir de pièces inutilisées après montage.In this context, the purpose of the present invention is to propose a security lighting unit free from the aforementioned limitations and, in particular, which makes it possible to implement the assembly functions of the light panel to the block support case in the two mounting states without having any spare parts after mounting.

A cette fin, le bloc d'éclairage de sécurité de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que ledit couvercle comprend des connecteurs destinés à venir s'engager, dans ledit premier état de montage, avec ledit cadre, ledit cadre présentant une section externe définissant un logement destiné à recevoir à emboîtement lesdits connecteurs dans ledit second état de montage.To this end, the security lighting unit of the invention, moreover in accordance with the generic definition given in the preamble above, is essentially characterized in that said cover comprises connectors intended to engage in said first mounting state, with said frame, said frame having an outer section defining a housing for snugly receiving said connectors in said second mounting state.

Grâce à cet agencement, le cadre peut être fixé au couvercle suivant les deux états de montage, sans nécessiter aucune pièce détachée spécifique pour l'un ou l'autre des deux états de montage.With this arrangement, the frame can be attached to the cover in both mounting states, without requiring any specific spare parts for either of the two mounting states.

Avantageusement, lesdits connecteurs sont deux tenons latéraux réalisés d'une seule pièce avec ledit couvercle et disposés sur des côtés opposés longitudinalement de ladite face frontale, destinés à venir se clipser chacun, dans ledit premier état de montage, dans une encoche correspondante pratiquée sur une partie de paroi interne transversale dudit cadre.Advantageously, said connectors are two lateral pins made in one piece with said cover and disposed on opposite sides longitudinally of said front face, intended to come each clip, in said first mounting state, in a corresponding notch made on a transverse inner wall portion of said frame.

Avantageusement encore, ledit cadre présente une section externe en V ou en U, dont deux ailes longitudinales faisant saillie d'une paroi interne longitudinale dudit cadre définissent ledit logement, ledit logement étant en forme de mortaise.Advantageously, said frame has an outer section V or U, two longitudinal wings projecting from a longitudinal inner wall of said frame defining said housing, said housing being in the form of a mortise.

Ainsi, les moyens permettant l'assemblage du panneau lumineux au couvercle dans les deux états de montage, participent avantageusement à procurer une esthétique améliorée du bloc. En effet, dans le premier état de montage, les tenons latéraux en face frontale du couvercle sont clipsés du côté intérieur du cadre profilé, ce qui les rend invisibles pour un observateur. De la même façon, les tenons latéraux sont rendus invisibles dans le second état de montage, dans la mesure où ils sont engagés à emboîtement dans un logement correspondant en forme de mortaise agencé entre deux ailes longitudinales délimitant une section externe en forme de V ou de U du cadre, de sorte que les deux ailes longitudinales du cadre masquent les tenons latéraux du couvercle qui y sont emboîtés dans le second état de montage. En outre, l'assemblage par tenon-mortaise est particulièrement favorable pour assurer la cohésion du panneau lumineux et du couvercle suivant une orientation perpendiculaire de ces pièces entre elles dans le second état de montage.Thus, the means for assembling the light panel to the cover in the two mounting states, advantageously participate in providing an improved aesthetics of the block. Indeed, in the first mounting state, the lateral tenons front end of the cover are clipped on the inner side of the profiled frame, which makes them invisible to an observer. In the same way, the lateral tenons are made invisible in the second mounting state, insofar as they are engaged in a corresponding slot-shaped housing arranged between two longitudinal wings delimiting a V-shaped external section or U of the frame, so that the two longitudinal wings of the frame mask the lateral tenons of the lid which are nested in the second mounting state. In addition, the tenon-mortise assembly is particularly favorable for ensuring the cohesion of the light panel and the cover in a perpendicular orientation of these parts together in the second mounting state.

En variante, les connecteurs pourraient également être constitués par des moyens de fixation magnétiques ou électromagnétiques, adaptés pour fixer le couvercle au panneau lumineux dans les deux états de montage par coopération avec des sites de fixation magnétique correspondant prévus sur le cadre du panneau lumineux.Alternatively, the connectors could also be constituted by magnetic or electromagnetic fixing means adapted to fix the cover to the light panel in the two mounting states by cooperation with corresponding magnetic attachment sites provided on the frame of the light panel.

En référence aux figures 1 à 3, le bloc d'éclairage de sécurité 1 de l'invention comprend un boîtier support 2 destiné à être rapporté en saillie sur une paroi de montage, tel qu'un mur ou un plafond. Le boîtier support 2 comprend un socle (non représenté), formant patère de fixation, destiné à être fixé par sa paroi de fond au mur ou au plafond, et venant être fermé en face avant, opposée à la paroi de fond, par un couvercle 20, présentant une face frontale rectangulaire 21, bordée par une paroi latérale 22 s'étendant selon un contour rectangulaire, de façon à définir avec le socle un logement d'accueil 23 pour un mécanisme d'appareillage électrique du bloc (non représenté), comprenant typiquement un circuit électronique pour l'alimentation électrique du bloc, des contacts électriques ainsi qu'éventuellement des accumulateurs. Le couvercle 20 du boîtier support 2 présente globalement une forme de parallélépipède allongé. Il s'étend ainsi en longueur selon un axe longitudinal X, en largeur selon un axe transversal Y et en épaisseur selon un axe frontal Z. En position d'implantation sur un mur (figures 1 et 2), le couvercle 20 du boîtier support 2 est rapporté sur la paroi murale de telle sorte que son axe longitudinal X s'étende horizontalement à la paroi murale, que son axe transversal Y s'étende verticalement et que son axe frontal Z s'étende perpendiculairement à la paroi murale. En position d'implantation sur un plafond (figure 2), le couvercle 20 du boîtier support 2 est rapporté sur la paroi de plafond de telle sorte que son axe longitudinal X et son axe transversal Y s'étendent horizontalement à la paroi de plafond et que son axe frontal Z s'étende perpendiculairement à la paroi de plafond.With reference to Figures 1 to 3 , the safety lighting unit 1 of the invention comprises a support housing 2 intended to be projectingly mounted on a mounting wall, such as a wall or a ceiling. The support housing 2 comprises a base (not shown), forming a fixing bracket, intended to be fixed by its bottom wall to the wall or ceiling, and being closed in the front face, opposite the bottom wall, by a cover 20, having a rectangular front face 21, bordered by a side wall 22 extending in a rectangular outline, so as to define with the base a receiving housing 23 for an electrical equipment mechanism of the block (not shown), typically comprising an electronic circuit for powering the block, electrical contacts and possibly accumulators. The cover 20 of the support housing 2 generally has an elongate parallelepiped shape. It thus extends in length along a longitudinal axis X, in width along a transverse axis Y and in thickness along a front axis Z. In implantation position on a wall ( Figures 1 and 2 ), the cover 20 of the support housing 2 is attached to the wall wall so that its longitudinal axis X extends horizontally to the wall, that its transverse axis Y extends vertically and that its front axis Z extends perpendicular to the wall. In implantation position on a ceiling ( figure 2 ), the cover 20 of the support housing 2 is attached to the ceiling wall so that its longitudinal axis X and its transverse axis Y extend horizontally to the ceiling wall and that its front axis Z extends perpendicular to the ceiling wall.

Le couvercle 20 du boîtier support du bloc est préférentiellement réalisé d'une seule pièce par moulage d'un matériau plastique rigide, tel que le polycarbonate.The cover 20 of the support housing of the block is preferably made in one piece by molding a rigid plastic material, such as polycarbonate.

Le bloc comprend également un panneau lumineux 3 constitué d'au moins une étiquette de signalisation 31, illustrant une information de sécurité, telle que par exemple la présence d'une sortie de secours, et d'un guide de lumière 32, réunis à leur périphérie par un cadre 30. Le cadre 30 est préférentiellement un cadre profilé rectangulaire 30 en matériau plastique. Le cadre profilé rectangulaire 30 est réalisé d'une seule pièce par moulage d'un matériau plastique, tel que le polycarbonate. On prévoit que les dimensions de longueur et de largeur du cadre profilé rectangulaire 30 coïncident avec celles de la face frontale rectangulaire 31 du couvercle 20 du boîtier support du bloc, sur laquelle le panneau lumineux 30 est destiné à être monté, soit dans un plan parallèle à cette dernière dans un premier état de montage, soit dans un plan perpendiculaire à cette dernière, dans un second état de montage.The block also comprises a light panel 3 consisting of at least one signaling label 31, illustrating a security information, such as for example the presence of an emergency exit, and a light guide 32, joined to their periphery by a frame 30. The frame 30 is preferably a rectangular profiled frame 30 of plastic material. The Rectangular profiled frame 30 is made in one piece by molding a plastic material, such as polycarbonate. It is expected that the length and width dimensions of the rectangular profiled frame 30 coincide with those of the rectangular front face 31 of the cover 20 of the block support housing, on which the light panel 30 is intended to be mounted, or in a parallel plane. to the latter in a first mounting state, in a plane perpendicular to the latter, in a second mounting state.

La figure 4 illustre une vue en coupe selon le plan (X-Z) du bloc de sécurité de l'invention dans le premier état de montage et la figure 5 illustre une vue en coupe selon le plan (Y-Z) du bloc du bloc de sécurité de l'invention dans le second état de montage.The figure 4 illustrates a sectional view along the plane (XZ) of the security block of the invention in the first mounting state and the figure 5 illustrates a sectional view along the plane (YZ) of the block of the security block of the invention in the second mounting state.

Comme illustré plus précisément sur les vues en coupe des figures 4 et 5, la partie périphérique extérieure du cadre profilé 30 présente une section transversale, dite section externe du cadre, en forme de « V » ouvert vers l'extérieur et dont la base constitue des parois internes transversales 33 et longitudinales 34, délimitant l'intérieur du cadre profilé 30, où sont logés l'étiquette de signalisation 31 et le guide de lumière 32. Deux ailes transversales 35, légèrement divergentes, s'étendent en saillie, dirigées vers l'extérieur, depuis chaque paroi interne transversale 33 du cadre et eux ailes longitudinale 36, légèrement divergentes, s'étendent en saillie, dirigées vers l'extérieur, depuis chaque paroi interne longitudinale 33 du cadre 30. Ici, le cadre profilé 30 présente une section en V avec ses deux ailes latérales, respectivement suivant la direction transversale et la direction longitudinale, qui divergent l'une par rapport à l'autre à partir de la base mais, en variante, il pourrait présenter une section en U avec ses deux ailes latérales parallèles.As illustrated more precisely on the sectional views of figures 4 and 5 , the outer peripheral portion of the profiled frame 30 has a cross section, said outer section of the frame, in the form of a "V" open towards the outside and whose base constitutes transverse 33 and longitudinal internal walls 34, delimiting the interior of the profiled frame 30, which are housed the signaling label 31 and the light guide 32. Two transverse wings 35, slightly divergent, extend projecting, directed outwards, from each transverse inner wall 33 of the frame and they longitudinal flanges 36, slightly divergent, extend projecting, directed outwards, from each longitudinal inner wall 33 of the frame 30. Here, the profiled frame 30 has a V-shaped section with its two lateral wings, respectively in the direction transverse and the longitudinal direction, which diverge relative to each other from the base but, alternatively, it could have a U-shaped section with ec its two parallel lateral wings.

Comme on le voit mieux sur la figure 5, la face interne des parois internes longitudinales 34 du cadre 30, c'est-à-dire la face orientée vers l'intérieur du cadre, à l'opposé des ailes longitudinales 36 par rapport à la paroi interne longitudinale 34, est pourvue d'une rainure longitudinale 37, destinée à positionner et maintenir des bords inférieur et supérieur respectivement du guide de lumière 32 et de l'étiquette de signalisation 31 au sein du cadre profilé 30.As we see better on the figure 5 , the inner face of the longitudinal inner walls 34 of the frame 30, that is to say the face oriented towards the inside of the frame, opposite the longitudinal wings 36 with respect to the longitudinal inner wall 34, is provided with a longitudinal groove 37 for positioning and maintaining lower and upper edges respectively of the light guide 32 and the signaling label 31 within the profiled frame 30.

Par ailleurs, et comme illustré à la figure 5, le cadre profilé rectangulaire 30 est pourvu d'une source lumineuse 4, se présentant sous la forme d'un circuit imprimé allongé, disposé selon l'exemple de réalisation contre une face externe de la paroi interne longitudinale supérieure 34 du cadre profilé 30 (« supérieure » s'entendant ici dans la position du bloc 1 tel qu'il est représenté sur la figure 5), et sur lequel est montée alignée une pluralité de diodes électroluminescentes. Le circuit imprimé allongé de la source lumineuse 4 est par exemple fixé par collage le long de cette face externe de la paroi interne longitudinale supérieure 34 du cadre 30. La paroi interne longitudinale supérieure 34 est pourvue d'une pluralité d'ouvertures dans lesquelles est disposée la pluralité de diodes électroluminescentes portées par le circuit imprimé lorsque ce dernier est fixé contre la face externe de la paroi interne longitudinale supérieure du cadre profilé 30.Moreover, and as illustrated in figure 5 the rectangular profiled frame 30 is provided with a light source 4, in the form of a elongated printed circuit, arranged according to the embodiment example against an outer face of the upper longitudinal inner wall 34 of the profiled frame 30 ("upper" here meaning in the position of the block 1 as shown in FIG. figure 5 ), and on which is mounted aligned a plurality of light emitting diodes. The elongate printed circuit of the light source 4 is for example fixed by gluing along this outer face of the upper longitudinal inner wall 34 of the frame 30. The upper longitudinal inner wall 34 is provided with a plurality of openings in which is disposed the plurality of light emitting diodes carried by the printed circuit when the latter is fixed against the outer face of the upper longitudinal inner wall of the profiled frame 30.

Le guide de lumière 32, se présentant sous la forme d'une plaque par exemple réalisée en polymétacrylate de méthyl (en abrégé PMMA, de l'anglais Polymethyl Methacrylate), est monté à l'intérieur du cadre profilé 30, de sorte que son bord supérieur logé dans la rainure longitudinale 37 pratiquée dans la face externe de la paroi interne longitudinale supérieure vienne en regard desdites ouvertures, pour former une surface de couplage optique avec les diodes électroluminescentes de la source lumineuse 6. La lumière émise par les diodes électroluminescentes est émise latéralement dans le guide de lumière 32. Ce dernier comprend une première surface, formant une surface de diffusion de la lumière vers l'étiquette de signalisation 31 disposée sus-jacent, préférentiellement par l'intermédiaire d'un film mince diffusant (non représenté), par exemple d'une épaisseur de l'ordre de la centaine de microns et réalisé en PC (polycarbonate) ou PET (polyéthylène téréphtalate), et destiné à être intercalé entre le guide de lumière 32 et l'étiquette de signalisation 4 lors du montage de l'ensemble dans le cadre profilé 30 afin d'homogénéiser la lumière émise. Le guide de lumière 32 comprend aussi une seconde surface opposée à la première surface, et sur laquelle est formé un réseau de microlentilles pour diriger la lumière conduite dans le guide de lumière vers le film diffusant. Ces microlentilles, par exemple sphériques, forment ainsi une couche d'extraction du guide de lumière 32 permettant d'améliorer l'extraction de lumière vers le film diffusant. Un film réfléchissant, non représenté, peut en outre être disposé adjacent à cette seconde surface du guide de lumière 32.The light guide 32, in the form of a plate for example made of polymethyl methacrylate (abbreviated to PMMA), is mounted inside the profiled frame 30, so that its upper edge housed in the longitudinal groove 37 formed in the outer face of the upper longitudinal inner wall comes opposite said openings, to form an optical coupling surface with the light-emitting diodes of the light source 6. The light emitted by the light-emitting diodes is emitted laterally in the light guide 32. The latter comprises a first surface, forming a light diffusing surface towards the signaling label 31 disposed above, preferably via a thin film diffusing (not shown ), for example with a thickness of the order of one hundred microns and made of PC (polycarbonate) or PET (polyethylene t réphtalate), and intended to be interposed between the light guide 32 and the signaling tag 4 when mounting the assembly in the frame profile 30 in order to homogenize the light emitted. The light guide 32 also includes a second surface opposite to the first surface, and on which is formed an array of microlenses for directing the light conducted in the light guide to the scattering film. These microlenses, for example spherical, thus form an extraction layer of the light guide 32 making it possible to improve the extraction of light towards the diffusing film. A reflective film, not shown, may also be disposed adjacent to this second surface of the light guide 32.

Le guide de lumière, le film diffusant et l'étiquette de signalisation sont montés maintenus en contact plan entre eux et réunis à leur périphérie par le cadre profilé 30, de façon à constituer le panneau lumineux 3 du bloc.The light guide, the diffusing film and the signaling label are mounted in plane contact with each other and joined at their periphery by the profiled frame 30, so as to constitute the light panel 3 of the block.

On va maintenant décrire plus précisément l'assemblage du panneau lumineux 3 au couvercle 20 du boîtier support du bloc. Comme déjà décrit, le panneau lumineux peut être assemblé au couvercle 20 suivant deux états de montage, respectivement un premier état de montage, où le panneau lumineux 3 s'étend dans un plan parallèle à la face frontale 21 du couvercle 20, correspondant à une configuration d'implantation du bloc sur un mur, et un second état de montage, où le panneau lumineux 3 s'étend dans un plan perpendiculaire à la face frontale 21 du couvercle 20, correspondant à une configuration d'implantation du bloc sur un plafond.We will now describe more precisely the assembly of the light panel 3 to the cover 20 of the support housing of the block. As already described, the light panel can be assembled to the cover 20 in two mounting states, respectively a first mounting state, where the light panel 3 extends in a plane parallel to the front face 21 of the cover 20, corresponding to a configuration of implantation of the block on a wall, and a second mounting state, where the light panel 3 extends in a plane perpendicular to the front face 21 of the cover 20, corresponding to a configuration of implantation of the block on a ceiling .

Pour ce faire, le couvercle 20 comprend deux tenons latéraux 24, 25, disposés sur des côtés opposés longitudinalement de la face frontale 21 du couvercle 20. Les deux tenons latéraux 24, 25 sont préférentiellement disposés suivant un plan médian longitudinal du couvercle 20. Ils sont préférentiellement venus de moulage, d'une seule pièce avec le reste du couvercle 20. Ils sont adaptés pour permettre d'assujettir le panneau lumineux 3 au couvercle 20, dans les deux états de montage.To do this, the cover 20 comprises two lateral lugs 24, 25, arranged on opposite sides longitudinally of the front face 21 of the lid 20. The two lateral lugs 24, 25 are preferably arranged in a longitudinal median plane of the lid 20. They are preferably molded integrally with the rest of the cover 20. They are adapted to allow to secure the light panel 3 to the cover 20 in the two mounting states.

Le premier état de montage est décrit en référence à la figure 4. Les tenons latéraux 24 et 25 sont destinés, dans ce premier état de montage, à venir se clipser chacun, dans une encoche correspondante 330 pratiquée sur la face interne de la paroi interne transversale 33 du cadre profilé 30, lorsque ce dernier, amené en surplomb de la face frontale 21 du couvercle 20, en étant disposé parallèlement à celle-ci, vient être appliqué à force contre elle. Lors de cette opération, le cadre profilé 30, qui présente une certaine souplesse de part sa forme, se déforme, permettant ainsi l'introduction des tenons latéraux 24, 25 dans leur encoche correspondante 330 prévue en face interne de la paroi interne transversale 30 du cadre. Les tenons latéraux 24, 25 comportent un bord rigide 240, 250 faisant saillie du corps du tenon et destiné à s'insérer dans ladite encoche 330. Lorsque les tenons latéraux 24, 25 sont insérés dans leur encoche correspondante 330 respective, le cadre profilé 30 est maintenu fixé au couvercle 20 dans un plan parallèle à la face frontale 21 de ce dernier, en masquant avantageusement les tenons latéraux, et est superposé au couvercle de façon sensiblement jointive, c'est-à-dire de manière compacte, sans espace entre eux. En outre, dans cet état de montage, la partie périphérique externe du cadre profilé 30 est sensiblement alignée avec la paroi latérale 22 du couvercle 20. L'ensemble forme alors un bloc particulièrement compact.The first mounting state is described with reference to the figure 4 . The lateral tenons 24 and 25 are intended, in this first state of assembly, to be clipped each, in a corresponding notch 330 formed on the inner face of the transverse inner wall 33 of the profiled frame 30, when the latter, brought overhanging the front face 21 of the cover 20, being arranged parallel thereto, is forcibly applied against it. During this operation, the profiled frame 30, which has a certain flexibility due to its shape, is deformed, thus allowing the insertion of the lateral tenons 24, 25 into their corresponding notch 330 provided on the internal face of the transverse inner wall 30 of the frame. The lateral tenons 24, 25 comprise a rigid edge 240, 250 protruding from the body of the tenon and intended to fit into said notch 330. When the lateral tenons 24, 25 are inserted into their corresponding notch 330, the profiled frame 30 is held fixed to the cover 20 in a plane parallel to the front face 21 of the latter, advantageously masking the lateral tenons, and is superimposed on the cover substantially contiguous, that is to say in a compact manner, without space between them. In addition, in this mounting state, the outer peripheral portion of the profile frame 30 is substantially aligned with the side wall 22 of the cover 20. The assembly then forms a particularly compact block.

Le second état de montage du panneau lumineux au couvercle est maintenant décrit en référence à la figure 5. Dans ce second état de montage, le panneau lumineux 3 est destiné à être assemblé au couvercle 20 en étant disposé dans un plan perpendiculaire à la face frontale 21 du couvercle 20. Pour ce faire, les tenons latéraux 24, 25 agencés sur la face frontale 21 du couvercle 20 sont prévus cette fois-ci pour coopérer avec les ailes longitudinales 36 faisant saillie vers l'extérieur de la paroi interne longitudinale supérieure 34 du cadre profilé 30. Plus précisément, les deux ailes longitudinales 36 de la paroi interne longitudinale supérieure 34 du cadre profilé, définissent entre elles, à chacune de leurs extrémités respectives, un logement 38 en forme de mortaise, agencé en surplomb de la face externe de la paroi interne longitudinale supérieure 34 et destiné à recevoir à emboîtement les tenons latéraux 24, 25 dans le second état de montage. Ainsi, chaque logement 38 présente un profil d'emboîtement complémentaire du profil des tenons latéraux 24, 25, dans lequel ces derniers peuvent s'engager par coulissement, à la manière d'un tenon dans une mortaise. Les tenons latéraux présentent par exemple, en coupe transversale, un profil ayant une section en forme de trapèze. Le profil d'emboîtement des logements 38 définis entre les deux ailes longitudinales 36, résulte avantageusement du même procédé de fabrication par moulage du cadre profilé. Les tenons latéraux 24, 25, une fois insérés dans leur logement 38 en forme de mortaise correspondant au profil d'emboîtement défini entre les deux ailes longitudinales 36, permettent de maintenir le cadre profilé 30 dans un plan perpendiculaire à la face frontale 21 du couvercle, tout en étant masqué de l'extérieur par les ailes longitudinales 36. En outre, le cadre profilé 30, dans ce second état de montage, est monté mobile en translation le long de sa paroi interne longitudinale supérieure 34, ce qui facilite les opérations de montage et démontage du cadre.The second mounting state of the light panel to the cover is now described with reference to the figure 5 . In this second mounting state, the light panel 3 is intended to be assembled to the cover 20 by being disposed in a plane perpendicular to the front face 21 of the cover 20. To do this, the lateral tenons 24, 25 arranged on the front face 21 of the cover 20 are provided this time to cooperate with the longitudinal wings 36 protruding outwardly from the upper longitudinal inner wall 34 of the profiled frame 30. More specifically, the two longitudinal wings 36 of the upper longitudinal inner wall 34 of the profiled frame, define between them, at each of their respective ends, a housing 38 in the shape of a mortise, arranged overhanging the outer face of the upper longitudinal inner wall 34 and intended to receive interlocking lateral tenons 24, 25 in the second mounting state. Thus, each housing 38 has a complementary interlocking profile of the profile of the lateral tenons 24, 25, in which they can engage by sliding, in the manner of a tenon in a mortise. The lateral tenons have for example, in cross section, a profile having a trapezoidal section. The interlocking profile of the housings 38 defined between the two longitudinal wings 36, advantageously results from the same manufacturing process by molding the profiled frame. The lateral tenons 24, 25, once inserted into their housing 38 in the form of a mortise corresponding to the interlocking profile defined between the two longitudinal wings 36, make it possible to maintain the profiled frame 30 in a plane perpendicular to the front face 21 of the lid , while being masked from the outside by the longitudinal wings 36. In addition, the profiled frame 30, in this second mounting state, is mounted to move in translation along its upper longitudinal inner wall 34, which facilitates the operations mounting and dismounting the frame.

Pour l'alimentation électrique de la source lumineuse 6 équipant le panneau lumineux 3, il est nécessaire de raccorder les contacts électriques agencés dans le logement d'accueil 23 du boîtier support à des bornes de connexion électrique du circuit imprimé à diodes électroluminescentes constituant la source lumineuse 6. Pour ce faire, on peut prévoir que des câbles conducteurs électriques circulent depuis le logement d'accueil et sortent par un orifice prévu à cet effet en face frontale du couvercle afin d'établir ladite connexion électrique entre les contacts électriques dans le logement d'accueil et les bornes de connexion électrique du circuit imprimé à diodes électroluminescentes. L'orifice de sortie de câble est prévu le long du plan longitudinal médian du couvercle entre les deux tenons latéraux, de sorte que dans le second état de montage, ledit orifice soit débouchant entre les ailes longitudinales du cadre profilé. Ainsi, les ailes longitudinales permettent de masquer les câbles.For the power supply of the light source 6 equipping the light panel 3, it is necessary to connect the electrical contacts arranged in the reception housing 23 of the support housing to terminals of electrical connection of the printed circuit with light-emitting diodes constituting the light source 6. To do this, provision may be made for electrical conducting cables to flow from the receiving housing and exit through an orifice provided for this purpose on the front face of the cover in order to establishing said electrical connection between the electrical contacts in the receiving housing and the electrical connection terminals of the light-emitting diode printed circuit. The cable exit orifice is provided along the median longitudinal plane of the cover between the two lateral tenons, so that in the second mounting state, said orifice is opening between the longitudinal wings of the profiled frame. Thus, the longitudinal wings can hide the cables.

En variante, les deux tenons latéraux 24, 25 comportent un insert métallique adapté pour permettre le contact avec les contacts électriques dans le logement d'accueil. Autrement dit, chaque tenon est recouvert au moins en partie d'un insert métallique, lequel est adapté pour s'étendre dans le logement d'accueil jusqu'aux contacts électriques au travers d'une ouverture agencée en face frontale du couvercle, au pied du tenon. Chaque encoche 330 et chaque logement 38, adaptés à coopérer avec les deux tenons latéraux 24, 25, pour réaliser l'assemblage du cadre profilé 30 sur le couvercle 20 dans les deux états de montage, sont également pourvus de plages de connexion métalliques, qui sont adaptées pour être mis en contact avec l'insert métallique des tenons latéraux 24, 25 dans chacun des deux états de montage respectifs. Les bornes de connexion électrique du circuit imprimé à diodes électroluminescentes sont alors reliées à ces plages de connexion métalliques par des pistes conductrices qui sont disposées directement sur le cadre profilé 30. Aussi, selon cette variante, la connexion électrique des bornes de la source lumineuse 6 équipant le cadre profilé 30 avec les contacts électriques au sein du logement d'accueil du boîtier support est avantageusement réalisée concomitamment à l'assemblage du cadre profilé 30 sur le couvercle 20, par la seule mise en relation des moyens participant à l'assemblage, d'une part par clipsage, s'agissant des tenons 24, 25 et encoches 330 dans le premier état de montage et, d'autre part, par emboîtement, s'agissant des tenons 24, 25 et logements 38 dans le second état de montage, sans qu'aucune autre action ne soit nécessaire pour un installateur.Alternatively, the two lateral lugs 24, 25 comprise a metal insert adapted to allow contact with the electrical contacts in the receiving housing. In other words, each post is covered at least in part with a metal insert, which is adapted to extend into the receiving housing to the electrical contacts through an opening arranged on the front face of the cover, at the foot of the tenon. Each notch 330 and each housing 38, adapted to cooperate with the two lateral tenons 24, 25, to assemble the profiled frame 30 on the cover 20 in the two mounting states, are also provided with metal connection pads, which are adapted to be brought into contact with the metal insert of the lateral tenons 24, 25 in each of the two respective mounting states. The electrical connection terminals of the printed circuit with light-emitting diodes are then connected to these metal connection pads by conductive tracks which are arranged directly on the profiled frame 30.
