Abstract

The main lamp body (10) has a silvered concave surface (12), acting as a reflector, with centrally mounted light source (20). The front-glass (30) embodies on its inner surface, an array of parallel e.g. horizontally aligned convex ridges (31). Immediately behind is fitted a transparent screen (40) whose inner surface is provided with a ridged array, similar but e.g. vertically aligned. Both optical surfaces may extend (31',41') over areas (10') of the main body outside the emitting cavity (11). The striated surfaces may face each other and form a dust and dirt-proof enclosure. One surface may also include prismatic striations triangular in cross-section, or be modified in other optically significant ways.

Description

La présente invention concerne d'une façon générale les feux de signalisation pour véhicules automobiles.The present invention relates generally to signaling lights for motor vehicles.

Une préoccupation qui de nos jours prend une importance croissante dans la conception des feux de signalisation est celle de l'aspect extérieur du feu lorsqu'il est éteint.A concern which is gaining increasing importance in the design of traffic lights these days is that of the exterior appearance of the light when it is out.

On recherche notamment, dans certains feux, à créer une illusion de profondeur de la cavité du feu située en arrière du voyant, la profondeur réelle de cette cavité, délimitée par le socle du feu, étant quant à elle de l'ordre de grandeur de la dizaine de centimètres.We seek in particular, in certain lights, to create an illusion of depth of the cavity of the light located behind the sight glass, the real depth of this cavity, delimited by the base of the light, being in turn of the order of magnitude of about ten centimeters.

On connaît déjà dans l'état de la technique un feu de signalisation destiné à restituer cette illusion de profondeur. Un tel feu est représenté schématiquement sur les figures 1 et 2.We already know in the prior art a signaling light intended to restore this illusion of depth. Such a fire is shown schematically in Figures 1 and 2.

Il comprend un socle 10 définissant au moins une cavité 11 dont le fond constitue un miroir généralement parabolique 12. Une lampe 20 est montée dans le fond 12 du socle et un voyant 30 ferme le socle à l'avant (par rapport à la direction d'émission de la lumière) de celui-ci. Pour atteindre l'effet de profondeur, le miroir 12 présente sur sa surface des stries 13 en forme de bandes verticales, réalisés par projection normale sur sa surface de stries cylindriques horizontales, tandis que le voyant 30 est équipé sur sa surface interne de stries cylindriques horizontales.It includes a base 10 defining at least one cavity 11, the bottom of which constitutes a generally parabolic mirror 12. A lamp 20 is mounted in the bottom 12 of the base and an indicator light closes the base at the front (relative to the direction of 'emission of light) from it. To achieve the effect of depth, the mirror 12 has on its surface ridges 13 in the form of vertical bands, produced by normal projection on its surface of horizontal cylindrical ridges, while the sight glass 30 is equipped on its internal surface with cylindrical ridges horizontal.

Lorsque le socle 10 est métallisé ou peint avec une peinture brillante, la conjugaison de la brillance obtenue avec les éléments optiques cylindriques du voyant permet de "voir" à l'intérieur du feu, et donne un effet de style dit "de profondeur".When the base 10 is metallized or painted with a glossy paint, the combination of the gloss obtained with the cylindrical optical elements of the indicator light makes it possible to "see" inside the light, and gives a so-called "depth" style effect.

Plus généralement, l'effet de profondeur est réalisé lorsque les bandes 13 du miroir 12 et les stries 31 du voyant présentent une orientation généralement perpendiculaire les unes par rapport aux autres.More generally, the depth effect is achieved when the bands 13 of the mirror 12 and the streaks 31 of the sight glass have an orientation generally perpendicular to each other.

Pour obtenir un effet de profondeur tout en conservant un miroir lisse, plus facile à fabriquer et moins coûteux, on pourrait utiliser les enseignements de FR-A-2 427 549, qui décrit un feu de signalisation conforme au préambule de la revendication 1.To achieve a depth effect while retaining a smooth mirror, easier to manufacture and less expensive, one could use the teachings of FR-A-2 427 549, which describes a traffic light in accordance with the preamble of claim 1.

Toutefois, lorsqu'un tel feu connu comporte une zone adjacente non fonctionnelle, définie par le socle, l'aspect de profondeur du feu tranche considérablement avec l'aspect de cette zone non fonctionnelle.However, when such a known light includes an adjacent non-functional zone, defined by the base, the depth aspect of the light contrasts considerably with the appearance of this non-functional zone.

La présente invention vise à pallier cette limitation de l'état de la technique et en particulier à proposer un feu de signalisation qui présente un aspect de profondeur régulier et uniforme même sur une étendue plus grande que la cavité proprement dite du feu.The present invention aims to overcome this limitation of the state of the art and in particular to propose a signaling light which has an appearance of regular and uniform depth even over a greater area than the actual cavity of the light.

Ainsi la présente invention propose un feu de signalisation tel que défini dans la revendication 1.Thus, the present invention provides a signaling light as defined in claim 1.

Des aspects préférés, mais non limitatifs, de l'invention sont définis dans les sous-revendications.Preferred, but not limiting, aspects of the invention are defined in the dependent claims.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante de formes de réalisation préférées de celle-ci, donnée à titre d'exemple non limitatif et faite en référence aux dessins annexés, sur lesquels, outre les figures 1 et 2 décrites plus haut :

  • la figure 3 est une vue schématique en perspective éclatée d'une partie d'un feu de signalisation à aspect de profondeur selon une première forme de réalisation de l'invention,
  • la figure 4 est une vue schématique en coupe horizontale d'un feu de signalisation à aspect de profondeur selon ladite première forme de réalisation,
  • la figure 5 est une vue schématique en perspective éclatée d'une partie d'un feu de signalisation à aspect de profondeur selon une deuxième forme de réalisation de l'invention,
  • la figure 6 est une vue schématique en perspective éclatée d'une partie d'un feu de signalisation à aspect de profondeur selon une troisième forme de réalisation de l'invention, et
  • la figure 7 est une vue schématique en coupe horizontale d'un feu de signalisation selon une quatrième forme de réalisation de l'invention.
Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of preferred embodiments thereof, given by way of non-limiting example and made with reference to the accompanying drawings, in which , in addition to Figures 1 and 2 described above:
  • FIG. 3 is a schematic exploded perspective view of part of a signaling light with a deep appearance according to a first embodiment of the invention,
  • FIG. 4 is a schematic view in horizontal section of a signaling light with a deep appearance according to said first embodiment,
  • FIG. 5 is a schematic exploded perspective view of part of a signaling light with a deep aspect according to a second embodiment of the invention,
  • Figure 6 is a schematic perspective view exploded view of part of a deep aspect signaling light according to a third embodiment of the invention, and
  • Figure 7 is a schematic horizontal sectional view of a signal light according to a fourth embodiment of the invention.

En référence aux figures 3 et 4, on a représenté un feu de signalisation qui comprend un socle 10 qui définit au moins une cavité 11 dont le fond constitue un miroir 12 par exemple du genre parabolique et qui reçoit une source lumineuse telle qu'une lampe à filament 20.Referring to Figures 3 and 4, there is shown a signaling light which comprises a base 10 which defines at least one cavity 11 whose bottom constitutes a mirror 12 for example of the parabolic type and which receives a light source such as a lamp filament 20.

En avant du socle (par rapport à la direction d'éclairement), le feu comprend une glace ou voyant de fermeture 30. Entre le voyant et le socle est prévu, au voisinage et à distance essentiellement constante du voyant, un écran intermédiaire 40.In front of the base (with respect to the direction of illumination), the light comprises a lens or closing indicator 30. Between the indicator and the base is provided, in the vicinity and at essentially constant distance from the indicator, an intermediate screen 40.

Pour donner au feu de signalisation un aspect de profondeur homogène et indépendant de l'angle d'observation, l'écran intermédiaire 40 possède, en l'espèce sur sa face intérieure, des stries verticales convexes 41 ayant de préférence toutes même largeur et même courbure, tandis que le voyant 30 possède, également sur sa face intérieure, des stries horizontales convexes 31 ayant également de préférence toutes même largeur et même courbure.To give the signaling light an aspect of homogeneous depth independent of the viewing angle, the intermediate screen 40 has, in this case on its inner face, convex vertical ridges 41 preferably all having the same width and even curvature, while the sight glass 30 also has on its inner face, convex horizontal ridges 31 also preferably all having the same width and same curvature.

L'aspect de profondeur est réalisé par la seule présence de l'écran intermédiaire et du voyant, conjointement au fait qu'en arrière de ces éléments, le socle présente un aspect au moins relativement brillant, en étant de préférence aluminié, de façon indépendante de la distance entre le socle et l'écran intermédiaire. Ainsi l'aspect de profondeur est obtenu dans le cas de la figure 4 non seulement au niveau de la cavité 11, mais également au niveau d'une zone non fonctionnelle dans laquelle le socle 10 comporte un prolongement 10' s'étendant à proximité de l'écran 40, grâce au fait que des stries 31', 41' identiques aux stries 31, 41 sont prévues également dans cette région sur le voyant et sur l'écran.The depth aspect is achieved by the mere presence of the intermediate screen and the indicator, together with the fact that behind these elements, the base has an appearance that is at least relatively glossy, preferably being aluminized, independently the distance between the base and the intermediate screen. Thus the aspect of depth is obtained in the case of FIG. 4 not only at the level of the cavity 11, but also at the level of a non-functional zone in which the base 10 has an extension 10 ′ extending close to the screen 40, thanks to the fact that the ridges 31 ′, 41 ′ are identical the lines 31, 41 are also provided in this region on the indicator and on the screen.

De façon préférée, la distance entre l'écran intermédiaire 40 et le voyant 30 est comprise entre 0,5 et 3 mm, tandis que le pas des stries 31, 31' et 41, 41' est compris entre 3 et 12 mm. Bien entendu, les pas des stries horizontales et des stries verticales peuvent être différents l'un de l'autre.Preferably, the distance between the intermediate screen 40 and the indicator 30 is between 0.5 and 3 mm, while the pitch of the ridges 31, 31 'and 41, 41' is between 3 and 12 mm. Of course, the steps of the horizontal streaks and the vertical streaks may be different from each other.

Par ailleurs, l'écran et le voyant peuvent comporter des stries d'orientations quelconques pour autant que les stries de l'un des éléments soient orientées essentiellement perpendiculairement à celles de l'autre élément.Furthermore, the screen and the indicator light may have any orientation streaks provided that the streaks of one of the elements are oriented essentially perpendicular to those of the other element.

En outre, selon une variante non illustrée, les stries du voyant et de l'écran peuvent être concaves. Selon une autre variante, les stries de l'écran peuvent être prévues sur la face de celui-ci tournée vers le voyant.In addition, according to a variant not illustrated, the streaks of the indicator and of the screen can be concave. According to another variant, the streaks of the screen can be provided on the face of the latter facing the indicator.

En référence maintenant à la figure 5, on a représenté une forme de réalisation de l'invention dans laquelle le voyant comporte non seulement les stries 31, mais également des trièdres catadioptriques indiqués en 32.Referring now to FIG. 5, there is shown an embodiment of the invention in which the sight glass comprises not only the streaks 31, but also catadioptric trihedra indicated at 32.

De préférence, ces trièdres sont organisés en bandes de deux rangées de catadioptres parallèles et alternées avec une strie 31 (comme illustré sur la figure 5) ou un groupe de telles stries.Preferably, these trihedra are organized in strips of two rows of parallel and alternating retro-reflectors with a streak 31 (as illustrated in FIG. 5) or a group of such streaks.

Dans cette réalisation, l'écran intermédiaire 40 est de façon préférée raccordé de façon étanche au voyant au niveau de leurs bords, de manière à former avec lui une enceinte étanche protégeant les trièdres catadioptriques vis-à-vis des poussières, des salissures, etc..., comme l'exigent les règlements.In this embodiment, the intermediate screen 40 is preferably connected in a sealed manner to the sight glass at their edges, so as to form with it a sealed enclosure protecting the catadioptric trihedra against dust, dirt, etc. ..., as required by the regulations.

La figure 6 illustre une variante de réalisation de la figure 5 dans laquelle les stries 41 de l'écran intermédiaire sont remplacés par des tores 42, c'est-à-dire par des éléments présentant une courbure à la fois en direction horizontale et en direction verticale. Par exemple, les tores peuvent présenter un pas horizontal de 3 à 6 mm et un pas vertical de 6 à 24 mm.FIG. 6 illustrates an alternative embodiment of FIG. 5 in which the ridges 41 of the intermediate screen are replaced by toroids 42, that is to say by elements having a curvature both in horizontal direction and in vertical direction. By example, the toroids can have a horizontal pitch of 3 to 6 mm and a vertical pitch of 6 to 24 mm.

Dans ce cas, l'effet de profondeur continue à être assuré, tandis que les tores 42 permettent de concentrer la lumière issue du miroir 12 vers les régions du voyant 30 où se trouvent les stries 31, en évitant au moins partiellement les éléments catadioptriques 32.In this case, the depth effect continues to be ensured, while the toroids 42 make it possible to concentrate the light coming from the mirror 12 towards the regions of the sight glass 30 where the streaks 31 are located, at least partially avoiding the retro-reflecting elements 32 .

Grâce à cette solution, le rendement lumineux du feu est amélioré dans la mesure où la lumière qui est normalement perdue (par réflexion totale ou par dispersion horizontale ou verticale importante) lorsqu'elle arrive sur les trièdres cadadioptriques est en partie récupérée.Thanks to this solution, the light output of the fire is improved to the extent that the light which is normally lost (by total reflection or by significant horizontal or vertical dispersion) when it arrives on the cadadioptric trihedra is partly recovered.

Maintenant en référence à la figure 7, on a illustré une autre forme de réalisation de l'invention dans laquelle on donne au feu lorsqu'il est éteint une teinte différente de la couleur de la lumière émise. En l'espèce, l'écran intermédiaire 40 comporte sur sa face extérieure un revêtement coloré (réalisé par sérigraphie, par marquage à chaud, etc...) sous forme de bandes horizontales rouges 43 alternées avec des bandes dépourvues de revêtement. En outre, l'écran intermédiaire 40 est teinté en jaune-vert, tandis que le voyant est teinté en rose.Now with reference to FIG. 7, another embodiment of the invention has been illustrated in which a tint different from the color of the light emitted is given when the fire is out. In this case, the intermediate screen 40 has on its outer face a colored coating (produced by screen printing, by hot stamping, etc.) in the form of horizontal red bands 43 alternated with bands without coating. In addition, the intermediate screen 40 is tinted yellow-green, while the indicator is tinted pink.

Dans ce cas, la lumière ayant traversé l'écran 40 et le voyant 30 est ambre, tandis que le feu éteint présente un aspect rose.In this case, the light having passed through the screen 40 and the indicator 30 is amber, while the extinguished fire has a pink appearance.

Bien entendu, d'autres combinaisons sont possibles.Of course, other combinations are possible.

On observera ici que l'importance en surface des bandes de revêtement 43 par rapport aux bandes dépourvues de revêtement est choisie de manière à laisser passer une quantité suffisante de flux lumineux tout en donnant une teinte aussi marquée que possible à l'état éteint.It will be observed here that the surface importance of the coating strips 43 relative to the strips without coating is chosen so as to allow a sufficient amount of light flux to pass while giving a shade as marked as possible in the extinct state.

Bien entendu, la présente invention n'est nullement limitée aux formes de réalisation décrites et représentées, mais l'homme de l'art saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is not limited to the embodiments described and shown, but those skilled in the art will be able to make any variant or modification in accordance with his spirit.
