The lid and the metallic part are assembled with each other and disposed on both sides of the plate, where the lid is adapted to traverse the plate and realized in a material to be traversed by light rays. The metallic part is realized in a material permitting to evacuate heat released by the diode.

Description

La présente invention est relative à un dispositif lumineux destiné,The present invention relates to a light device intended for

notamment, aux panneaux de signalisation.  in particular, signs.

Il est connu de réaliser des panneaux, en matière transparente ou translucide, comportant des inscriptions, gravées par exemple sur l'une de leurs faces, les dites inscriptions étant visuellement mises en relief par l'envoi d'un rayon lumineux dans l'épaisseur de la plaque constituant le panneau.  It is known to produce panels, in transparent or translucent material, comprising inscriptions, engraved for example on one of their faces, said inscriptions being visually highlighted by sending a light beam in the thickness. of the plate constituting the panel.

Généralement, l'éclairement est réalisé par une batterie de diodes disposées linéairement au-dessus du champ supérieur du panneau. Cette disposition est rendue nécessaire du fait que les rayons lumineux s'étendent sensiblement selon l'axe géométrique de la diode. Le résultat n'est pas satisfaisant car une partie des rayons lumineux est perdue et ne pénètre pas dans la plaque. Il faut signaler, aussi, que les diodes forment une rampe qui doit comporter un moyen de fixation qui est distinct de celui du panneau.  Generally, the illumination is achieved by a battery of diodes arranged linearly above the upper field of the panel. This arrangement is made necessary because the light rays extend substantially along the geometric axis of the diode. The result is not satisfactory because part of the light rays is lost and does not enter the plate. It should be noted, too, that the diodes form a ramp which must include a fixing means which is distinct from that of the panel.

Depuis peu, une nouvelle génération de diodes est apparue sur le marché, lesdites diodes étant capables d'émettre des rayons situés sensiblement dans un plan s'étendant perpendiculairement à l'axe géométrique de la diode.  Recently, a new generation of diodes has appeared on the market, said diodes being capable of emitting rays located substantially in a plane extending perpendicularly to the geometric axis of the diode.

L'invention met à profit l'utilisation de cette nouvelle diode pour réaliser un panneau de signalisation incorporant sa source d'éclairage.  The invention takes advantage of the use of this new diode to make a signaling panel incorporating its lighting source.

Selon l'invention, la diode est maintenue dans un orifice du panneau de façon à ce que son axe géométrique s'étende perpendiculairement audit panneau.  According to the invention, the diode is maintained in an orifice of the panel so that its geometric axis extends perpendicular to said panel.

De cette façon, les rayons lumineux émis par la diode sont intégralement transmis, sans perte, au panneau en s'étendant parallèlement à ses faces.  In this way, the light rays emitted by the diode are integrally transmitted without loss to the panel extending parallel to its faces.

Selon un mode de réalisation, la diode est maintenue en position par l'entremise d'un boîtier en deux parties, assemblées l'une sur l'autre et disposée, chacune, de part et d'autre du panneau, l'une des parties qui traverse le panneau étant transparente et l'autre étant métallique pour favoriser l'évacuation de la chaleur produite par la diode.  According to one embodiment, the diode is held in position by means of a housing in two parts, assembled one on the other and arranged, each, on either side of the panel, one of the parts passing through the panel being transparent and the other being metallic to promote the evacuation of the heat produced by the diode.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé à titre d'exemple indicatif, seulement, sur lequel : - la figure 1 est une vue éclatée, en coupe verticale, montrant les composants du dispositif de l'invention ; - la figure 2 est une vue analogue à la figure 1, les composants du dispositif étant représentés en position d'utilisation.  The present invention will be better understood from the following description made with reference to the accompanying drawing by way of indicative example only, in which: FIG. 1 is an exploded view, in vertical section, showing the components of the device of FIG. the invention; - Figure 2 is a view similar to Figure 1, the components of the device being shown in the use position.

Le problème consiste à envoyer des rayons lumineux à travers l'épaisseur d'une plaque 1, transparente ou translucide, comportant des inscriptions gravées ou fixées par un moyen adhésif. L'envoi des rayons lumineux fait apparaître les inscriptions.  The problem consists in sending light rays through the thickness of a plate 1, transparent or translucent, with inscriptions engraved or fixed by an adhesive means. The sending of the luminous rays makes appear the inscriptions.

Le but de l'invention vise un dispositif permettant d'utiliser, comme source de lumière, une diode 2 ayant la particularité d'émettre des rayons lumineux sensiblement dans un plan perpendiculaire à son axe géométrique XY.  The object of the invention is to provide a device for using, as a light source, a diode 2 having the particularity of emitting light rays substantially in a plane perpendicular to its geometric axis XY.

Selon l'invention, la diode 2 est maintenue dans une ouverture 3 de la plaque 1 de façon à ce que son axe géométrique XY s'étende perpendiculairement au plan de ladite plaque.  According to the invention, the diode 2 is held in an opening 3 of the plate 1 so that its geometric axis XY extends perpendicular to the plane of said plate.

Selon un mode de réalisation, la diode est maintenue par un boîtier en deux parties 4 et 5. La partie 4, ou couvercle, traverse la plaque 1 et s'étend au-delà de cette dernière pour recevoir la partie 5. Comme cela ressort de l'exemple représenté, la plaque 1 est emprisonnée entre l'épaulement 6 du couvercle 4 et l'extrémité 5a de la partie 5.  According to one embodiment, the diode is held by a two-part housing 4 and 5. Part 4, or cover, passes through the plate 1 and extends beyond the latter to receive the part 5. As is apparent of the example shown, the plate 1 is trapped between the shoulder 6 of the cover 4 and the end 5a of the portion 5.

15 Le couvercle 4 présente un évidement 7 permettant le logement de la partie active de la diode 2.  The lid 4 has a recess 7 allowing the housing of the active part of the diode 2.

La partie du couvercle comprise dans l'épaisseur de la plaque est réalisée en une matière pouvant être traversée librement par les rayons 20 lumineux.  The portion of the lid included in the thickness of the plate is made of a material that can be traversed freely by the light rays.

La diode 2 est fixée sur une embase 8, métallique, pouvant prendre appui sur un épaulement 9 de la partie 5, également métallique. De cette façon, la partie 5 peut évacuer la chaleur dégagée par la diode. Comme cela ressort de la figure 2, un organe élastiquement déformable, tel qu'un joint torique 1 0, est interposé entre l'extrémité 4a du couvercle et l'embase 8. Lorsque le couvercle 4 est vissé à fond, comme 25 montré sur la figure 2, l'organe 10 est comprimé et applique l'embase 8 contre l'épaulement 9. Sur les dessins, les câbles d'alimentation ne sont pas représentés, mais il est évident qu'il convient de raccorder les câbles usuels qui sortent de la diode, et qui traversent librement l'embase 8, au câble provenant du secteur d'alimentation qui pénètre dans la partie 5 par un orifice 1 1. Selon l'invention, un espace 1 2 est prévu dans la partie 5 pour loger les organes de raccordement.10  The diode 2 is fixed on a base 8, metal, which can bear on a shoulder 9 of the part 5, also metallic. In this way, the part 5 can evacuate the heat released by the diode. As can be seen from FIG. 2, an elastically deformable member, such as an O-ring 10, is interposed between the end 4a of the cover and the base 8. When the cover 4 is screwed down as shown in FIG. 2, the member 10 is compressed and applies the base 8 against the shoulder 9. In the drawings, the power cables are not shown, but it is obvious that it is necessary to connect the usual cables which out of the diode, and which freely pass through the base 8, to the cable coming from the power supply sector which enters the part 5 through a hole 1 1. According to the invention, a space 1 2 is provided in part 5 to accommodate the connection components.10
