Description

La présente invention concerne un dispositif de variation d'intensité lumineuse en corrélation avec l'éclairage ambiant. The present invention relates to a device for varying the light intensity in correlation with ambient lighting.

Cette invention s'insère dans l'évolution des techniques afférentes à la régulation du trafic automobile et autre similaire. This invention is part of the evolution of techniques relating to the regulation of automobile traffic and the like.

L'état de l'art actuel nous montre divers dispositifs tendant à résoudre le problème lié à la meilleure perception possible des feux de croisement tricolores. The current state of the art shows us various devices tending to solve the problem linked to the best possible perception of the tri-color low beams.

On observera, dans cet esprit le brevet nO 2.395.561 du 23 juin 1977 qui décrit une invention améliorant, selon l'auteur, la visibilité des feux tricolores grâce à une forme géométrique particulière des sources lumineuse s. In this spirit, patent No. 2,395,561 of June 23, 1977 which describes an invention improving, according to the author, the visibility of three-color lights thanks to a particular geometric shape of the light sources, will be observed.

Un autre brevet nO 2.428.290 décrit une invention dans laquelle des soupapes dites optiques pourraient améliorer les performances des feux tricolores. Another patent No. 2,428,290 describes an invention in which so-called optical valves could improve the performance of traffic lights.

Le brevet n0 2.459.517 décrit une invention dans laquelle l'amélioration de l'intensité lumineuse est obtenue par utilisation d'un ensemble électro-optique utilisant notamment un réflecteur parabolique. Patent No. 2,459,517 describes an invention in which the improvement of the light intensity is obtained by the use of an electro-optical assembly using in particular a parabolic reflector.

Dans un brevet nO 2.588.109, il apparaît que la perception visuelle des feux rouge, orange ou vert est obtenue grâce à l'alimentation répartie de diodes électroluminescentes. In patent No. 2,588,109, it appears that the visual perception of red, orange or green lights is obtained by the distributed supply of light-emitting diodes.

Enfin, le brevet nO 2.460.511 décrit un dispositif économiseur d'énergie. Finally, patent No. 2,460,511 describes an energy saving device.

Ces divers brevets, représentatifs de l'état de l'art actuel, démontrent la complexité avec laquelle leurs inventeurs respectifs ont tenté de résoudre ces difficultés. These various patents, representative of the current state of the art, demonstrate the complexity with which their respective inventors tried to resolve these difficulties.

La présente invention se propose d'obvier à tous ces inconvénients et présente comme grand avantage sa relative simplicité. The present invention proposes to overcome all these drawbacks and has the great advantage of its relative simplicity.

Ladite invention utilise une lanterne classique avec feux tricolores équipés d'une cellule photoélectrique intégrée qui permet de capter l'intensité de l'éclairement ambiant, lequel éclairement sera transmis sous forme électrique à des circuits de mesure et de régulation et autre automati sme. Said invention uses a conventional lantern with three-color lights equipped with an integrated photoelectric cell which makes it possible to capture the intensity of the ambient illumination, which illumination will be transmitted in electrical form to measurement and regulation circuits and other automation.

Le traitement de ces signaux électriques permettra, grâce à des moyens électroniques de commande et de puissance, de fournir l'éclairement adéquat afin d' obtenir à distance la meilleure perception visuelle des feux de cette lanterne. The processing of these electrical signals will, thanks to electronic control and power means, provide adequate lighting in order to obtain the best visual perception of the lights of this lantern from a distance.

Une autre caractéristique de ladite invention concerne une lampe de défaut du feu rouge, située sur la partie supérieure de la lanterne, qui cochère avec une autre lampe dite "lampe de secours" située à l'intérieur du feu rouge de ladite lanterne. Another characteristic of said invention relates to a red light fault lamp, located on the upper part of the lantern, which coches with another lamp called "emergency lamp" located inside the red light of said lantern.

ba présente invention sera mieux comprise et les avantages d'utilisation apparaitront clairement au regard de la description suivante et des figures qui s'y rapportent et qui représentent
- la figure 1 représente une lanterne complète,
- la figure 2 représente des éléments de commande et de contrôle des feux de ladite lanterne.
ba present invention will be better understood and the advantages of use will become clear from the following description and the figures relating thereto and which represent
FIG. 1 represents a complete lantern,
- Figure 2 shows the command and control elements of the lights of said lantern.

En nous reportant à la figure 1, nous voyons que la lanterne 1 possède une cellule photoélectrique 2 et un ensemble de feux tricolores rouge 3, jaune 4, et vert 5. Chaque feu est équipé d'une lampe 12, figure 2. Referring to Figure 1, we see that the lantern 1 has a photocell 2 and a set of red 3, yellow 4, and green 5 traffic lights. Each light is equipped with a lamp 12, Figure 2.

La cellule photoélectrique 2 est insérée dans la lanterne 1 dans l'axe optique de ladite lanterne ou en d'autres termes dans l'axe de vision d'un usager de la route face à elle. The photocell 2 is inserted into the lantern 1 in the optical axis of said lantern or in other words in the line of vision of a road user facing it.

Cette cellule photoélectrique transmet, sous forme de signaux électriques, à un circuit de mesure 6, figure 2, l'information résultant de la mesure de l'éclairement ambiant. This photoelectric cell transmits, in the form of electrical signals, to a measurement circuit 6, FIG. 2, the information resulting from the measurement of the ambient illumination.

Ledit circuit de mesure 6 est lié à un comparateur 7 dont le seuil ou niveau de déclenchement du signal est obtenu grâce à un potentiomètre 8 qui détermine le niveau du signal de commande 9 qui attaque le gradateur à triac 10 ce gradateur attaque lui-mene le circuit de puissance 11 qui donne, d'une part, l'intensité électrique adéquate pour obtenir l'intensité lumineuse requise, en égard aux conditions d'éclairement ambiant et, d'autre part, alimente le cas échéant la lampe de secours 13 lors de la mise hors service du feu rouge 3. Simultanément, un circuit de détection de défaut 14 donne l'ordre à un circuit de puissance 15 d'alimenter la lampe de défaut 16 située sur la partie supérieure de la lanterne ainsi que la lampe de secours 13 située à l'intérieur de l'optique du feu rouge 3. Said measuring circuit 6 is linked to a comparator 7 whose threshold or trigger level of the signal is obtained by means of a potentiometer 8 which determines the level of the control signal 9 which attacks the triac dimmer 10 this dimmer attacks it leads the power circuit 11 which gives, on the one hand, the adequate electric intensity to obtain the required light intensity, taking into account the ambient lighting conditions and, on the other hand, supplies if necessary the emergency lamp 13 during when the red light goes out of service 3. Simultaneously, a fault detection circuit 14 gives the order to a power circuit 15 to supply the fault lamp 16 located on the upper part of the lantern as well as the emergency 13 located inside the red light optics 3.

Une source de courant à tension adéquate et formé d'onde idoine 17 alimente à la fois les circuits de traitement des informations du signal et des circuits de puissance. A current source with an adequate voltage and a suitable wave 17 supplies both the signal information processing circuits and the power circuits.

Un des autres avantages de cette invention consiste notamment en l'économie d 'énergie électrique consommée pouvant atteindre 50% de l'énergie habituellement dépensée dans une lanterne dont on sait que la consommation électrique est de l'ordre de 200 watts. One of the other advantages of this invention consists in particular in saving electrical energy consumed which can reach 50% of the energy usually spent in a lantern of which it is known that the electrical consumption is of the order of 200 watts.

En outre, un autre avantage de la présente invention est la constance de la perception visuelle des feux de la lanterne par l'usager automobiliste ou autre. In addition, another advantage of the present invention is the consistency of the visual perception of the lantern lights by the motorist or other user.

Ceci est fort important car les variations d'éclairement diurne et nocturne sont dans un rapport de plus de lOt) selon les cas. This is very important because the variations in day and night illumination are in a ratio of more than lOt) depending on the case.

La présente invention a pour finalité une amélioration de la facilité de perception des feux de la lanterne dans des conditions d'éclairement ambiant ainsi que la visualisation rapide d'un défaut sur le feu principal rouge par le ou les techniciens de maintenance. En outre, un service minimum est assuré par la lampe de secours du feu rouge.  The aim of the present invention is to improve the ease of perceiving the lantern lights under ambient lighting conditions as well as the rapid visualization of a fault on the main red light by the maintenance technician (s). In addition, minimum service is provided by the red light emergency lamp.
