Description

DISPOSITIF D'ECLAIRAGE PUBLIC  LIGHTING DEVICE
L'invention concerne un dispositif d'éclairage public, comportant un circuit alimenté électriquement en tension par un réseau de distribution et au moins une lampe reliée audit circuit et ayant une tension seuil de décrochage déterminée. The invention relates to a public lighting device, comprising a circuit electrically powered voltage by a distribution network and at least one lamp connected to said circuit and having a determined stall threshold voltage.
La présente invention entre dans le domaine de l'électricité, et plus particulièrement celui de l'abaissement de la tension d'un éclairage public.  The present invention is in the field of electricity, and more particularly that of lowering the voltage of a public lighting.
Dans le domaine de l'éclairage public, il est d'usage d'alimenter les lampadaires et autres moyens d'éclairage directement par le réseau de distribution d'électricité, les lampes fonctionnant alors à pleine puissance.  In the field of public lighting, it is customary to supply streetlights and other lighting directly through the electricity distribution network, the lamps then operating at full power.
Durant ces dernières années, les questions d'environnement et de réchauffement climatiques ont orienté les nouvelles technologies vers une diminution de la consommation d'énergie, et vers une sensibilisation aux conséquences environnementales.  In recent years, environmental issues and global warming have led new technologies to reduce energy consumption and awareness of environmental consequences.
Dans cette optique, on a vu se démocratiser les ampoules à basse consommation d'énergie qui permettent d'obtenir une luminosité équivalente pour une puissance consommée moindre, et donc ayant un effet bénéfique pour l'environnement.  With this in mind, we have seen the democratization of light bulbs with low energy consumption that achieve equivalent brightness for less power consumption, and therefore having a beneficial effect on the environment.
En ce qui concerne l'éclairage public, cette avancée technologique ne peut être prise en compte qu'au fur et a mesure du temps et des remplacements de cet éclairage, notamment suite à des pannes ou à la vétusté de l'installation.  As far as public lighting is concerned, this technological advance can only be taken into account as time passes and replacements of this lighting, in particular due to breakdowns or the dilapidated installation.
En effet, à l'heure actuelle il n'est pas possible d'utiliser des ampoules basses consommation sur l'éclairage public, car les installations électriques existantes ne le permettent pas et les ampoules en question ne sont pas capables de supporter la tension trop haute du réseau de distribution, qui les ferait griller ou exploser.  Indeed, at the moment it is not possible to use low energy bulbs on public lighting, because existing electrical installations do not allow it and the bulbs in question are not able to withstand the voltage too much. high of the distribution network, which would burn or explode.
Ainsi, à l'heure actuelle, les éclairages électriques publics sont équipés de trois types de lampes à savoir, les lampes Sodium Haute Pression (SHP) , les lampes à Vapeur de mercure (HQL) et les Iodures Métalliques (IM) . Ces lampes ont principalement été choisies en fonction de leur longue durée de vie et leur luminosité suffisante pour un éclairage en extérieur . Thus, at present, public electric lights are equipped with three types of lamps namely, high pressure sodium lamps (SHP), mercury vapor lamps (HQL) and metal halide (IM). These lamps were mainly chosen according to their long duration of life and their brightness sufficient for outdoor lighting.
Cependant, de telles lampes sont consommatrices en énergie et donc peu écologiques.  However, such lamps are energy consuming and therefore unecological.
De plus, le fonctionnement à pleine puissance de ces lampes réduit considérablement leur durée de vie, induisant une diminution de leur luminosité et obligeant leur remplacement de manière fréquent. Outre le coût plus élevé de telles lampes, ces remplacements entraînent un coût non négligeable pour une agglomération, notamment en raison des équipements nécessaires pour ces opérations, se déroulant généralement sur la voirie et en hauteur.  In addition, the full power operation of these lamps significantly reduces their life, causing a decrease in brightness and requiring their replacement frequently. In addition to the higher cost of such lamps, these replacements entail a non-negligible cost for an agglomeration, particularly because of the equipment necessary for these operations, generally taking place on the road and at height.
Il a déjà été proposé des économiseurs d'énergie qui abaissent la tension l'allumage de la lampe à décharge, permettant ainsi de réduire la consommation, comme cela ressort du document US 2002/101192.  It has already been proposed energy savers that lower the voltage ignition of the discharge lamp, thus reducing consumption, as is apparent from US 2002/101192.
On sait que chaque type de lampe nécessite une tension minimale pour être maintenue allumée, et en dessous de laquelle il y décrochage. Aussi, le document US 2002/101192 évoque des économiseurs qui comportent un système d'horloge permettant de gérer dans le temps l'allumage des lampes à pleine tension puis, après un certain temps, d'opérer une bascule pour abaisser la tension de fonctionnement. Ce document énonce également que ces économiseurs présentent toutefois l'inconvénient qu'en cas de panne temporaire de courant, il n'y a pas d'allumage possible, puisque celui-ci est géré dans le temps par l'horloge.  We know that each type of lamp requires a minimum voltage to be kept on, and below which there stall. Also, the document US 2002/101192 refers to economizers which include a clock system for managing over time the lighting of lamps at full voltage and then, after a while, to operate a rocker to lower the operating voltage . This document also states that these economizers however have the disadvantage that in case of temporary power failure, there is no ignition possible, since it is managed in time by the clock.
Ces économiseurs présentent un autre inconvénient à savoir leur relative complexité, et donc leur coût de fabrication et de mise en œuvre, au regard du nombre d'installations susceptibles d'être équipées.  These economizers have another drawback to know their relative complexity, and therefore their cost of manufacture and implementation, in view of the number of facilities likely to be equipped.
On notera que le document US 2002/101192 propose de remédier à l'inconvénient des économiseurs connus par l'ajout dans le circuit d'une seconde bobine, ce qui toutefois ne va pas dans le sens de la simplification. L'invention a pour but de pallier les inconvénients de l'état de la technique en proposant un système abaisseur de tension alimentant un éclairage public, permettant de diminuer la consommation dudit éclairage et d'augmenter la durée de vie des ampoules tout en produisant une luminosité suffisante. De plus un tel système présente l'avantage d'un montage rapide et simple sur une installation existante. It will be noted that document US 2002/101192 proposes to remedy the drawback of known economizers by adding a second coil to the circuit, which however does not go in the direction of simplification. The aim of the invention is to overcome the drawbacks of the state of the art by proposing a voltage-lowering system supplying a public lighting, making it possible to reduce the consumption of said lighting and to increase the life of the bulbs while producing a light. sufficient brightness. In addition, such a system has the advantage of a quick and simple assembly on an existing installation.
Ainsi, l'invention concerne un dispositif d'éclairage public, comportant un circuit alimenté électriquement en tension par un réseau de distribution et au moins une lampe reliée audit circuit et ayant une tension seuil de décrochage déterminée, caractérisé par le fait que ledit circuit comprend d'une part des moyens de transformation de ladite tension d'alimentation en une tension d'allumage inférieure, la valeur de ladite tension d'allumage étant comprise entre ladite tension seuil de décrochage et ladite tension d'alimentation; et d'autre part des moyens de commutation conçus aptes a permettre de sélectionner une valeur pour ladite tension d'allumage, ladite valeur correspondant au type de ladite lampe.  Thus, the invention relates to a public lighting device, comprising a circuit electrically powered by a voltage distribution network and at least one lamp connected to said circuit and having a determined stall threshold voltage, characterized in that said circuit comprises on the one hand means for transforming said supply voltage into a lower ignition voltage, the value of said ignition voltage being between said stall threshold voltage and said supply voltage; and secondly switch means designed to allow to select a value for said ignition voltage, said value corresponding to the type of said lamp.
Il est ainsi possible, en fonction du type de lampe utilisée, de sélectionner une tension d'allumage réduite, laquelle va être délivrée dès l'allumage.  It is thus possible, depending on the type of lamp used, to select a reduced ignition voltage, which will be delivered on ignition.
Selon une caractéristique additionnelle du dispositif d'éclairage public selon l'invention, lesdits moyens de transformation sont constitués par un autotransformateur comportant au moins deux sorties réglées chacune à une tension différente et comprise entre la tension d'alimentation du réseau et la tension seuil de décrochage de ladite lampe.  According to an additional characteristic of the public lighting device according to the invention, said transformation means are constituted by an autotransformer comprising at least two outputs each set at a different voltage and between the supply voltage of the network and the threshold voltage of stalling said lamp.
Selon une autre caractéristique du dispositif d'éclairage public selon l'invention, il comporte un commutateur prévu pour sélectionner l'une des sorties des moyens de transformation.  According to another characteristic of the public lighting device according to the invention, it comprises a switch provided for selecting one of the outputs of the transformation means.
Selon encore une autre caractéristique du dispositif d'éclairage public selon l'invention, il comporte une boucle «by-pass» conçue apte à contourner lesdits moyens de transformation pour alimenter ladite lampe avec ladite tension du réseau de distribution. According to yet another characteristic of the public lighting device according to the invention, it comprises a "bypass" loop designed adapted to bypass said means of transformation to supply said lamp with said distribution network voltage.
Selon une caractéristique additionnelle du dispositif d'éclairage public selon l'invention, il comporte encore des moyens pour protéger ledit dispositif contre les courts- circuits .  According to an additional characteristic of the public lighting device according to the invention, it also comprises means for protecting said device against short circuits.
D'autres caractéristiques et avantages du dispositif d'éclairage public selon l'invention ressortiront de la description détaillée qui va suivre d'un mode de réalisation non limitatif de l'invention représenté dans la figure annexée.  Other features and advantages of the public lighting device according to the invention will emerge from the detailed description which follows of a non-limiting embodiment of the invention shown in the attached figure.
Une telle figure représente schématiquement le circuit électrique de la présente invention.  Such a figure schematically represents the electric circuit of the present invention.
La présente invention entre dans le domaine de la régulation de tension et plus particulièrement de l'abaissement de la tension d'alimentation d'un éclairage public.  The present invention is in the field of voltage regulation and more particularly of lowering the supply voltage of a public lighting.
L'invention concerne un dispositif d'éclairage public 1. Un tel dispositif 1 peut se présenter sous la forme d'un éclairage direct ou indirect, sur pied tel un lampadaire, reporté à un édifice ou au sol, voire au moins en partie enterré ou immergé.  The invention relates to a public lighting device 1. Such a device 1 can be in the form of a direct or indirect lighting, on foot such as a lamp post, carried to a building or the ground, or at least partly buried or immersed.
Le dispositif 1 comprend un circuit alimenté électriquement par un réseau de distribution 2 au travers d'un bornier de connexion 3 comportant, avantageusement, trois entrées/sorties à savoir phase, neutre et terre. De manière générale, un tel réseau 2 délivre une tension alternative d'alimentation située aux alentours de 230 Volts (V) (à savoir qu'elle peut osciller de +/- 5 V) .  The device 1 comprises a circuit powered electrically by a distribution network 2 through a connection terminal block 3 advantageously comprising three inputs / outputs namely phase, neutral and earth. In general, such a network 2 delivers an alternating supply voltage located around 230 volts (V) (namely that it can oscillate by +/- 5 V).
Ledit circuit comprend au moins une lampe 4 reliée audit circuit par l'intermédiaire, là encore, d'un bornier de connexion 3a à trois entrées/sorties et s' allumant lorsqu'elle est parcourue par un courant électrique d'une tension minimum donnée.  Said circuit comprises at least one lamp 4 connected to said circuit via, again, a connection terminal block 3a with three inputs / outputs and lighting when it is traversed by an electric current of a given minimum voltage .
En particulier, en plus des caractéristiques évoquées précédemment, une telle lampe 4 comprend une tension seuil de décrochage déterminée. En somme, en dessous d'une valeur de tension d'alimentation, ladite lampe 4 ne s'allume pas, notamment en raison d'une excitation du gaz insuffisante. In particular, in addition to the features mentioned above, such a lamp 4 comprises a determined stall threshold voltage. In sum, below a value of supply voltage, said lamp 4 does not come on, in particular because of insufficient gas excitation.
En particulier, les lampes 4 utilisées présentent des tensions de décrochage aux alentours de 180 à 200 V.  In particular, the lamps 4 used have stalling voltages around 180 to 200 V.
L'invention consiste à modifier la tension d'allumage de ladite lampe 4, en l'abaissant sous la tension d'alimentation délivrée par ledit réseau de distribution 2. En somme, en diminuant la tension d'alimentation, on obtient une tension d'allumage moindre, faisant baisser d'autant la consommation électrique et énergétique de la lampe 4.  The invention consists in modifying the ignition voltage of said lamp 4 by lowering it under the supply voltage delivered by said distribution network 2. In short, by decreasing the supply voltage, a voltage of less ignition, lowering the power and energy consumption of the lamp 4.
Pour ce faire, ledit circuit comprend des moyens de transformation 5 de la tension d'alimentation en une tension d'allumage de ladite lampe 4.  To do this, said circuit comprises means 5 for transforming the supply voltage into an ignition voltage of said lamp 4.
Ces moyens de transformation 5 peuvent prendre la forme d'un transformateur mais on choisira de préférence un autotransformateur abaisseur de tension ne nécessitant qu'un seul enroulement de bobine pour fonctionner.  These transformation means 5 may take the form of a transformer, but a voltage-reducing autotransformer will preferably be selected requiring only a single coil winding to operate.
Plus particulièrement, lesdits moyens de transformation 5 permettent, en venant se brancher à différents niveaux de la bobine de cet autotransformateur, de diminuer la tension du réseau 2 pour délivrer une tension d'alimentation de la lampe 4 inférieure à ladite tension d'alimentation délivrée par le réseau 2.  More particularly, said transformation means 5 make it possible, by coming to connect to different levels of the coil of this autotransformer, to reduce the voltage of the network 2 to deliver a supply voltage of the lamp 4 less than said supply voltage delivered. by the network 2.
Plus particulièrement, ladite tension d'allumage est sélectionnée entre ladite tension de décrochage et ladite tension d'alimentation.  More particularly, said ignition voltage is selected between said stall voltage and said supply voltage.
Avantageusement, les moyens de transformation 5 comportent au moins deux sorties 6 présentant chacune une tension comprise entre la tension d'alimentation du réseau 2 et la tension de décrochage des lampes 4.  Advantageously, the transformation means 5 comprise at least two outputs 6 each having a voltage between the supply voltage of the network 2 and the stall voltage of the lamps 4.
Selon le mode préférentiel de l'invention visible sur la figure, le transformateur comporte quatre sorties 6 réglées chacune sur une valeur de la tension différente.  According to the preferred embodiment of the invention shown in the figure, the transformer has four outputs 6 each set to a different voltage value.
Ladite tension d'allumage est donc prévue pour atteindre une valeur au minimum supérieure audit seuil de décrochage. Une telle tension d'allumage peut être réglée de façon manuelle ou automatique, de manière à générer un éclairage suffisant de la lampe 4 en fonction de son emplacement, de son environnement et éventuellement des conditions environnantes, notamment climatiques . Said ignition voltage is therefore provided to reach a value at least greater than said stall threshold. Such an ignition voltage can be set manually or automatic, so as to generate sufficient illumination of the lamp 4 according to its location, its environment and possibly surrounding conditions, including climatic.
Tel qu'énoncé précédemment, les éclairages publics sont généralement équipés de trois types de lampe 4 , SHP, SQL et IM, qui ont chacune une valeur seuil de tension de décrochage différente. De plus, il convient de noter que cette tension de décrochage peut varier au cours du temps en fonction de l'usure de la lampe 4.  As previously stated, public lighting is generally equipped with three types of lamp 4, SHP, SQL and IM, each having a different threshold stall voltage value. In addition, it should be noted that this stall voltage can vary over time depending on the wear of the lamp 4.
Ainsi, le dispositif 1 selon l'invention, comporte un commutateur 7, permettant d'effectuer le réglage de la valeur de la tension alimentant la lampe 4, tension supérieure à la tension de décrochage de cette dernière et inférieure à ladite tension du réseau 2.  Thus, the device 1 according to the invention comprises a switch 7, making it possible to adjust the value of the voltage supplying the lamp 4, which voltage is greater than the stall voltage of the latter and lower than the said voltage of the network 2 .
D'une manière avantageuse, ledit commutateur 7 peut permettre de sélectionner plusieurs valeurs de tension entre la tension de décrochage de la lampe 4 et la tension du réseau 2 en se positionnant sur l'une des sorties 6 des moyens de transformation 5. En somme, ledit commutateur 7 est prévu pour s'adapter, d'une part au seuil de la tension de décrochage de chaque type de lampe 4 équipant les éclairages public et, d'autre part à la variation du seuil de cette tension de décrochage qui évolue en fonction du temps afin d'assurer le bon fonctionnement de l'éclairage public.  Advantageously, said switch 7 can make it possible to select several voltage values between the stall voltage of the lamp 4 and the voltage of the network 2 by positioning itself on one of the outputs 6 of the transformation means 5. In short , said switch 7 is designed to adapt, on the one hand, to the threshold of the stall voltage of each type of lamp 4 equipping the public lighting and, on the other hand, to the variation of the threshold of this evolving stalling voltage. as a function of time to ensure the proper functioning of public lighting.
Ce commutateur 7 se présente sous la forme d'un interrupteur qui est, d'une part relié au bornier de connexion 3a de la lampe 4 et, d'autre part peut se positionner soit sur une position de repos 8, tel que cela est visible sur la figure, soit sur l'une des sorties 6 des moyens de transformation 5 qui présentent une tension inférieure à celle du réseau 2.  This switch 7 is in the form of a switch which is, on the one hand, connected to the connection terminal block 3a of the lamp 4 and, on the other hand, can be positioned either in a rest position 8, as this is visible in the figure, or on one of the outputs 6 of the transformation means 5 which have a voltage lower than that of the network 2.
Selon une autre caractéristique de l'invention, le circuit du dispositif 1 comporte une seconde boucle 9 permettant de contourner les moyens de transformation 5 afin de venir alimenter la lampe 4 directement par la tension du réseau 2. Cette boucle 9 est plus communément appelée un « by-pass », elle permet en cas de maintenance ou de panne des moyens de transformation 5 de venir « shunter » ces derniers, afin de toujours alimenter la lampe 4 de l'éclairage public. According to another characteristic of the invention, the circuit of the device 1 comprises a second loop 9 making it possible to bypass the transformation means 5 in order to supply the lamp 4 directly by the voltage of the network 2. This loop 9 is more commonly called a "bypass", it allows in case of maintenance or failure of the transformation means 5 to "shunt" the latter, to always power the lamp 4 of public lighting.
A ce propos, l'on remarquera que ledit commutateur 7 est muni d'une position supplémentaire lui permettant de sélectionner cette boucle 9 dite « by-pass » de manière manuelle ou automatisée. Aussi, en cas de défaut le commutateur 7 peut venir automatiquement se placer sur cette position pour assurer l'éclairage de la lampe 4.  In this regard, it will be noted that said switch 7 is provided with an additional position allowing it to select this loop 9 called "bypass" manually or automated. Also, in the event of a fault, the switch 7 can come automatically to this position to ensure the lighting of the lamp 4.
D'une manière avantageuse et tel que cela est visible sur la figure, le dispositif 1 comporte encore des moyens 10 pour protéger le circuit du dispositif 1 ou un opérateur de maintenance lors de son utilisation.  Advantageously and as can be seen in the figure, the device 1 further comprises means 10 for protecting the circuit of the device 1 or a maintenance operator during its use.
Ces moyens de protection 10 sont de préférence un disjoncteur monté sur le circuit du dispositif 1.  These protection means 10 are preferably a circuit breaker mounted on the circuit of the device 1.
Plus particulièrement, les moyens de protection 10 sont prévus pour passer d'une position engagée à une position désengagée pour interrompre le courant entre le réseau 2 et les moyens de transformation 5 en cas de risque de court-circuit ou de surintensité.  More particularly, the protection means 10 are provided to move from an engaged position to a disengaged position to interrupt the current between the network 2 and the transformation means 5 in case of risk of short circuit or overcurrent.
Ainsi, ces moyens de protection 10 dans leur position engagée permettent le passage du courant aux moyens de transformation 5, ladite lampe 4 étant alors alimentée par une tension inférieure à la tension du réseau 2 et supérieure à la tension de décrochage de la lampe 4, tandis que dans leur position désengagée les moyens de transformation 5 sont contournés au profit de la boucle 9 « by-pass » pour alimenter la lampe 4 directement avec la tension du réseau 2.  Thus, these protection means 10 in their engaged position allow the passage of the current to the transformation means 5, said lamp 4 being then powered by a voltage lower than the voltage of the network 2 and greater than the stall voltage of the lamp 4, while in their disengaged position the transformation means 5 are bypassed in favor of the loop 9 "bypass" to supply the lamp 4 directly with the voltage of the network 2.
Par ailleurs, le dispositif 1 comporte des moyens de visualisation 11 qui se présentent sous la forme de deux diodes électroluminescentes 12 et 13, et permettent en cas d'intervention sur le dispositif 1 de mettre en évidence la présence ou non, d'une part, de la tension du réseau 2 aux bornes du dispositif, et d'autre part de la présence ou non de la tension aux bornes de la lampe 4. Ces diodes 12, 13 sont donc montées en parallèle aux bornes des borniers de connexion 3 et 3a entre la phase et le neutre. Furthermore, the device 1 comprises display means 11 which are in the form of two light-emitting diodes 12 and 13, and in the event of intervention on the device 1, make it possible to highlight the presence or absence of, on the one hand, , the voltage of the network 2 at the terminals of the device, and secondly the presence or absence of the voltage at the terminals of the lamp 4. These diodes 12, 13 are therefore connected in parallel across the terminal blocks 3 and 3a between the phase and the neutral.
Aussi l'invention a pour but de réduire la consommation en énergie de l'éclairage public au travers d'un dispositif simple, facile d'utilisation et peu coûteux.  Also the invention aims to reduce the energy consumption of public lighting through a simple device, easy to use and inexpensive.
