Abstract

The lamp includes a low-profile housing which encloses a dozen generally aligned light sources (preferably LEDs) (20) spaced 25 mm apart on an elongated printed circuit board. Emission from each hemispherical end (22) is concentrated by a cylindro-parabolic reflector (40) through the Fresnel lens (50) on to an array of scattering spheres or toroids (61) on the inside of a U-section moulding (60). The body (21) of each source is wider than the emissive hemisphere on to which the reflector and facets (51) of the Fresnel lens are focused. The hemisphere emits into a cone with a semi-vertical angle (θ ) of about 50 degrees , while the reflector restricts the angle of emission (phi) to 30-40 degrees .

Description

  • La présente invention concerne d'une façon générale les feux de signalisation comportant une pluralité de sources lumineuses de faible puissance et de petites dimensions, alignées, et des moyens de traitement de la lumière émise par ces sources pour former un faisceau de signalisation de photométrie adéquate. The present invention relates in general signal lights comprising a plurality of light sources of low power and small dimensions, aligned, and light processing means emitted by said sources to form an adequate photometry signaling beam .
  • Il peut s'agir par exemple des feux stop complémentaires, disposés au voisinage de la lunette arrière des véhicules automobiles. This can be eg additional brake lights, arranged in the vicinity of the rear window of motor vehicles. Les sources sont de préférence des diodes électroluminescentes. The sources are preferably LEDs.
  • Un feu stop doit émettre un faisceau lumineux relativement intense, aussi il est nécessaire de prévoir un nombre de sources relativement important, et proches les unes des autres. A fire stop must issue a relatively intense light beam, it is also necessary to provide a relatively large number of sources, and close to each other.
  • Les moyens connus pour former le faisceau à partir de la lumière diffusée par les sources sont de plusieurs types. The known means to form the beam from the light diffused by the sources are of several types.
  • Dans le document DE-A-43 05 585, on associe à chaque diode électroluminescente un dispositif optique du genre lentille de Fresnel disposée en avant de la diode. In DE-A-43 05 585, is associated with each light emitting diode device of an optical lens such Fresnel disposed in front of the diode. Cette solution est cependant désavantageuse en ce que pour récupérer la plus grande partie du flux lumineux émis par chaque diode électroluminescente, la hauteur de chaque lentille doit être importante, ce qui accroît l'encombrement du feu. This solution is however disadvantageous in that to recover most of the luminous flux emitted by each light emitting diode, the height of each lens must be large, which increases the bulk of the fire.
  • Dans le document JP-A-61 113290, qui correspond au préambule de la revendication 1, les diodes sont associées à un miroir récupérateur cylindrique à section du genre parabolique au foyer duquel sont placées les diodes. In JP-A-61 113290, which corresponds to the preamble of claim 1, the diodes are associated with a cylindrical mirror recuperator section of the parabolic type the focus of which the diodes are placed.
  • Une telle solution est cependant tout à fait inadaptée lorsque l'on utilise des diodes de type "Brewster", c'est-à-dire comportant un corps plus large que leur surface émissive. Such a solution is, however, quite unsuitable when using type diodes "Brewster", that is to say comprising a wider body than their emissive surface. En effet, le miroir récupérateur devrait alors être largement sur-dimensionné pour accueillir les diodes, très encombrantes, et la partie de fond de ce miroir, masquée par les corps des diodes, ne serait pas à même de remplir son rôle de récupération. In fact, the collector mirror should then be largely oversized to accommodate the diodes, very cumbersome, and the bottom portion of this mirror, masked by body diodes, would not be able to fulfill its role in recovery.
  • Avec ces moyens optiques, il est généralement nécessaire de prévoir de seize à vingt diodes électroluminescentes, espacées d'environ 15 mm. With these optical means, it is generally necessary to provide sixteen to twenty light emitting diodes spaced about 15 mm.
  • Afin de diminuer le coût de revient du feu, on peut chercher à diminuer le nombre diodes électroluminescentes, en les espaçant davantage les unes des autres pour une largeur de feu donnée. To reduce the cost of the fire, we can try to reduce the number LEDs in spacing them further apart for a particular fire wide. Mais dans ce cas, pour éviter une perte rédhibitoire de rendement optique, on est amené à accroître sensiblement la hauteur optique du feu, comme évoqué plus haut, et donc sa hauteur physique, pour récupérer une proportion accrue de la lumière émise par les sources. But in this case, to avoid a crippling loss of optical performance, it is necessary to significantly increase the optical fire height, as mentioned above, and therefore its physical height, to recover a greater proportion of the light emitted by the sources.
  • La présente invention vise à pallier ces limitations de l'état de la techniquen, et à proposer un feu de signalisation dans lequel l'espacement entre les différentes sources puisse être augmenté, tout en conservant une faible hauteur et sans perte significative de rendement optique. The present invention aims to overcome these limitations of the state of techniquen and propose a traffic light in which the spacing between the different sources can be increased while maintaining a low profile and no significant loss of optical performance.
  • L'invention propose à cet effet un feu de signalisation tel que défini dans la revendication 1. The invention provides for this purpose a signaling light as defined in claim 1.
  • Des aspects préférés, mais non limitatifs, du feu de signalisation selon l'invention sont définis dans les sous-revendications. Preferred, but not limiting, traffic light of the invention defined in the claims.
  • D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante d'une forme de réalisation préférée de celle-ci, donnée à titre d'exemple non limitatif et faite en référence au dessin annexé, sur lequel : Other aspects, objects and advantages of the present invention will become more apparent from reading the following detailed description of a preferred embodiment thereof given by way of example and with reference to the accompanying drawings, on which :
    • la figure 1 est une vue en coupe horizontale médiane d'un feu de signalisation selon la présente invention, Figure 1 is a median horizontal sectional view of a traffic signal according to the present invention,
    • la figure 2 est une vue de face du feu de la figure 1, Figure 2 is a front view of the fire of Figure 1,
    • la figure 3 est une vue en coupe selon la ligne III-III de la figure 1, Figure 3 is a sectional view along line III-III of Figure 1,
    • la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 1, Figure 4 is a sectional view along the line IV-IV of Figure 1,
    • la figure 5 illustre schématiquement des zones de traitements optiques différents du feu de la présente invention, et 5 schematically illustrates the optical treatment zones of different fire of the present invention, and
    • la figure 6 est une vue en coupe transversale à échelle agrandie illustrant le principe optique de la présente invention. Figure 6 is a cross-sectional enlarged view illustrating the optical principle of the present invention.
  • En référence aux figures, on a représenté un feu de signalisation, en l'espèce un feu stop complémentaire pour lunette arrière, qui comprend un boîtier 10 de forme allongée, fermé à l'avant (par rapport à la direction d'émission de la lumière, c'est-à-dire à gauche sur la figure 1 et à droite sur les figures 3 et 4) par un voyant 60 de profil en forme générale de "U". Referring to the figures, a fire shows signaling in this case a complementary stop lamp for the rear window which comprises a housing 10 of elongate shape, closed at the front (relative to the emission direction of the light, that is to say to the left in Figure 1 and to the right in figures 3 and 4) by a light 60 generally shaped profile of "U". Le boîtier est fixé sur le véhicule par des vis V engagées dans des trous formés dans le boîtier. The housing is fixed to the vehicle V by screws engaged in holes formed in the housing.
  • Dans le boîtier 10 est monté, par des moyens classiques, un circuit imprimé allongé 30 sur lequel sont soudées en alignement une pluralité de diodes électroluminescentes 20 de type classique, c'est-à-dire comportant un boîtier 21, une partie hémisphérique 22 d'émission de la lumière et deux pattes de connexion 23. La référence R désigne une résistance fixant le courant traversant les diodes 20. In the housing 10 is mounted, by conventional means, an elongate printed circuit board 30 on which are welded in alignment a plurality of LEDs 20 of conventional type, that is to say comprising a housing 21, a hemispherical portion 22 of emission of light and two connecting tabs 23. the reference R denotes a resistance fixing the current through the diodes 20.
  • Les diodes électroluminescentes 20 sont en l'espèce espacées d'environ 25 mm, et au nombre de douze, ces valeurs n'étant toutefois nullement limitatives. The LEDs 20 are in this case spaced about 25 mm, and twelve in number, these values ​​being, however, in no way limiting.
  • De façon connue en soi, chaque diode électroluminescente 20 émet de la lumière dans une indicatrice d'émission (angle solide couvert par le rayonnement) en forme de cône possédant un demi-angle au sommet θ d'environ 50°. In a manner known per se, each LED 20 emits light in a dummy emission (solid angle covered by the radiation) in the shape of cone having a half apex angle θ of about 50 °. Bien entendu, des sources possédant d'autres indicatrices d'émission peuvent être employées. Of course, sources with other emission indicator can be used.
  • Selon la présente invention, des doubles moyens optiques sont utilisés pour obtenir un faisceau de signalisation de photométrie appropriée. According to the present invention, optical means duplicates are used to obtain a photometry appropriate signaling beam.
  • Ces moyens consistent premièrement en un miroir 40, et secondement en une plaque 50 située entre les bords antérieurs du miroir et portant une série de reliefs formant des lentilles de Fresnel individuelles pour chacune des sources 20. These means consist in a first mirror 40, and secondly in a plate 50 located between the front edges of the mirror and carrying a series of reliefs forming individual Fresnel lenses for each source 20.
  • Le miroir 40 est en l'espèce un miroir cylindro-parabolique, dont la directrice est parallèle à la ligne passant par les différentes sources, et dont la génératrice est une parabole. The mirror 40 is in this case a parabolic mirror, whose director is parallel to the line through various sources, including the generator is a parabola. Son équation dans un repère orthonormé est donc du type y 2 = Ax (l'axe y s'étendant horizontalement suivant la direction générale d'émission, l'axe x étant vertical, et l'axe z s'étendant horizontalement suivant la ligne des sources). Its equation in an orthonormal therefore is of the type Ax = y 2 (y-axis extending horizontally in the general direction of emission, the x axis being vertical, and the z-axis extending horizontally along line sources). Le miroir 40 est focalisé sur la ligne passant par les différentes sources 20. The mirror 40 is focused on the line through the 20 different sources.
  • Le miroir 40 est fixé sur le circuit imprimé 30 par des entretoises 41 situées entre des diodes 20 adjacentes et reliées au miroir au niveau d'un fond plat 42 dudit miroir, inopérant du fait du cône d'émission réduit des sources. The mirror 40 is fixed on the circuit board 30 by spacers 41 between adjacent diodes 20 and connected to the mirror at a flat bottom 42 of said mirror, inoperative because of the cone reduced by the sources.
  • Les reliefs de la plaque optique 50 sont désignés par la référence 51 sur la figure 6, et peuvent se situer soit sur sa face interne, soit sur sa face externe (comme illustré). The reliefs of the optical plate 50 are designated by reference 51 in Figure 6, and can be located either on its internal surface or on its outer face (as illustrated). Les différentes lentilles de Fresnel formées par ces reliefs sont focalisées sur les sources respectives et possèdent des axes perpendiculaires à la ligne des sources. The different Fresnel lenses formed by these reliefs are focused on the respective sources and have axes perpendicular to the line of sources.
  • Comme le montre bien la figure 6, l'agencement du miroir 40 et de la plaque à lentilles de Fresnel 50 est tel qu'une partie du rayonnement conique émis par chaque source rencontre directement la lentille de Fresnel associée, et qu'une autre partie de ce rayonnement, plus à l'extérieur, rencontre les parties supérieure et inférieure du miroir 40 pour être redirigé, sensiblement horizontalement, vers les lentilles de Fresnel respectives. As shown clearly in Figure 6, the arrangement of the mirror 40 and the Fresnel lens plate 50 is such that part of the conical radiation emitted by each source directly encounter the Fresnel lens associated, and another portion this radiation outermost meets the upper and lower portions of the mirror 40 to be directed substantially horizontally towards the respective Fresnel lenses.
  • Plus précisément, les zones Z1 illustrent, dans un plan perpendiculaire à l'axe d'une source respective, la partie du rayonnement réfléchie par le miroir puis traversant la lentille de Fresnel, tandis que la zone Z2 illustre la partie du rayonnement arrivant directement sur la lentille de Fresnel. More specifically, the zones Z1 illustrate, in a plane perpendicular to the axis of a respective source, the portion of the radiation reflected by the mirror and passing through the Fresnel lens, while the region Z2 illustrates the portion of the radiation coming directly on the Fresnel lens.
  • La lumière émise vers la zone Z2 contribue principalement à permettre au feu de satisfaire à la grille photométrique règlementaire, en conjonction avec des billes ou tores 61 de diffusion de lumière formés sur la face interne du voyant, tandis que la lumière émise vers les zones Z1 contribue à un surcroit d'intensité lumineuse, ainsi qu'à rendre la plage éclairante du feu allumé plus homogène, notamment par le fait que le miroir est de type cylindrique et ne rabat pas la lumière émise latéralement vers l'axe optique. The light emitted to the zone Z2 contributes primarily to allow the fire to meet the full photometric grid in conjunction with balls or cores 61 of light diffusion formed on the inner face of the LED, while the light emitted to the zones Z1 contributes to extra light intensity, and to make the illuminating light illuminated more uniform, particularly in that the mirror is of cylindrical type and does not fold the laterally emitted light to the optical axis.
  • Le contour de la fenêtre de sortie de lumière pour la source considérée est désignée par F. The outline of the light output window for the source in question is designated by F.
  • L'angle des plans de transition, au-dessus et au-dessous de l'horizontale, entre les zones Z1 et Z2 est désigné par ϕ. The angle of the transition planes above and below the horizontal, between zones Z1 and Z2 is denoted by φ. Sa valeur est bien entendu inférieure à θ et de préférence de l'ordre de 30 à 40°. Its value is of course less than θ and preferably in the range of 30 to 40 °.
  • Grâce à la présente invention, on a pu réaliser un feu de signalisation comportant douze diodes électroluminescentes standard espacées de 25 mm, possédant une hauteur (au niveau du miroir 40 et de la plaque 50) de 10 mm, satisfaisant aux règlements en matière de photométrie, présentant une intensité plus que satisfaisante et une plage éclairante homogène. With the present invention it has been possible to realize a signal light having twelve spaced standard LEDs 25 mm, having a height (at the mirror 40 and the plate 50) of 10 mm satisfying the regulations photometry , having a more than satisfactory intensity and a uniform illuminating. Le tirage des lentilles de Fresnel était égal à 11 mm et l'équation du miroir 40 était y 2 = 2x. The draw Fresnel lenses was equal to 11 mm and the equation of the mirror was 40 y 2 = 2x.
  • Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite et représentée, 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 embodiment described and shown, but the man of the art can apply any variant or modification within the spirit.
  • Ainsi, de façon non illustrée, le miroir 40 peut venir de moulage lors de la fabrication du boîtier 10. Thus, non-illustrated way, the mirror 40 can be molded during manufacture of the housing 10.
