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 generally to signaling lights comprising a plurality of sources light bulbs of low power and small dimensions, aligned, and means for processing the light emitted by these sources to form a signaling beam of adequate photometry.
Il peut s'agir par exemple des feux stop complémentaires, disposés au voisinage de la lunette arrière des véhicules automobiles. Les sources sont de préférence des diodes électroluminescentes.It can be for example stop lights complementary, arranged in the vicinity of the rear window motor vehicles. The sources are preferably light emitting diodes.
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 stop light must emit a light beam relatively intense, also it is necessary to provide a relatively large number of sources, and close to each other others.
Les moyens connus pour former le faisceau à partir de la lumière diffusée par les sources sont de plusieurs types.Known means for forming the beam from the light scattered by the sources is 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. 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 accroít l'encombrement du feu.In document DE-A-43 05 585, each light emitting diode an optical device of the kind Fresnel lens arranged in front of the diode. This solution is however disadvantageous in that to recover most of the light flux emitted by each diode light-emitting, the height of each lens must be important, which increases the size of the fire.
Dans le document EP 0 633 163 A1, qui correspond au préambule de la revendication 1, les diodes électroluminescentes, de type "Brewster", sont associées à des miroirs récupérateurs coniques respectifs, les différents ensembles source lumineuse/miroir conique/lentille étant répartis sur un feu à grande plage éclairante.In document EP 0 633 163 A1, which corresponds to preamble of claim 1, the diodes "Brewster" type electroluminescent lamps are associated with respective conical recovery mirrors, the different light source / conical mirror / lens assembly spread over a light with a large illuminating surface.
Une telle solution est cependant tout à fait inadaptée lorsqu'avec de telles diodes, comportant un corps plus large que leur surface émissive, on cherche à diminuer le coût de revient du feu en diminuant le nombre diodes électroluminescentes et en les espaçant davantage les unes des autres pour une largeur de feu donnée. En effet, dans ce cas, pour éviter une perte rédhibitoire de rendement optique, on est amené à accroítre sensiblement la récupération de la lumière au niveau de chaque diode en accroissant 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.Such a solution is however entirely unsuitable when with such diodes having a larger body as their emissive surface, we seek to decrease the cost of comes back from the fire by decreasing the number of diodes light-emitting and spacing them further apart others for a given width of fire. Indeed, in this case, to avoid an unacceptable loss of optical efficiency, we is brought to significantly increase the recovery of light at each diode by increasing the height fire optics, as mentioned above, and therefore its height physical, to recover an increased proportion of light issued by sources.
La présente invention vise à pallier ces limitations de l'état de la technique, 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 the art, and to propose a traffic light in which the spacing between the different sources can be increased, while maintaining a low height and without significant loss of optical efficiency.
L'invention propose à cet effet un feu de signalisation tel que défini dans la revendication 1.The invention proposes 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 revendications dépendantes.Preferred, but not limiting, aspects of signaling according to the invention are defined in the dependent claims.
D'autres aspects, buts et avantages de la présente
invention apparaítront 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 :
En référence aux figures, on a représenté un feu de
signalisation, en l'espèce un feu stop complémentaire pour
lunette arrière, qui comprend un boítier 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". Le boítier est fixé
sur le véhicule par des vis V engagées dans des trous formés
dans le boítier.With reference to the figures, a fire of
signaling, in this case an additional brake light for
rear window, which includes a
Dans le boítier 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 boítier 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
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
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 d'environ 50°. Bien entendu, des sources possédant d'autres indicatrices d'émission peuvent être employées.In a manner known per se, each diode light emitting 20 emits light in a emission indicator (solid angle covered by the radiation) in the form of a cone having a half angle at vertex of about 50 °. Of course, sources with other emission indicators may 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, double means optics are used to get a beam of appropriate photometry signaling.
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 firstly of a
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. Son équation dans un repère orthonormé est
donc du type y2 = 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). Le miroir 40 est focalisé sur la ligne
passant par les différentes sources 20.The
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
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). 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 reliefs of the
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 in Figure 6, the arrangement of the
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 precisely, the zones Z1 illustrate, in a plane perpendicular to the axis of a respective source, the part of radiation reflected by the mirror and then crossing the Fresnel lens, while zone Z2 illustrates the part of the radiation arriving directly on the lens from Fresnel.
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 towards zone Z2 contributes
mainly to allow the fire to satisfy the grate
regulatory photometric, in conjunction with beads
or light scattering
Le contour de la fenêtre de sortie de lumière pour la source considérée est désignée par F.The outline of the light exit window for the source considered 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. Sa valeur est bien entendu inférieure à et de préférence de l'ordre de 30 à 40°.The angle of the transition planes, above and below horizontally, between zones Z1 and Z2 is designated by ϕ. Its value is of course less than and preferably of the order 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. Le tirage des lentilles de
Fresnel était égal à 11 mm et l'équation du miroir 40 était
y2 = 2x.Thanks to the present invention, it has been possible to produce a fire
signaling device with twelve diodes
standard LEDs spaced 25 mm apart, having
a height (at the level of the
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, pour autant que l'invention demeure telle que définie par les revendications.Of course, the present invention is by no means limited to the embodiment described and shown, but a person skilled in the art will know how to make any variant or modification according to his spirit, as long as the invention remains such as defined by the claims.
Ainsi, de façon non illustrée, le miroir 40 peut venir
