Description

DISPOSITIF ELECTRIQUE D'ALIMENTA ION  ELECTRICAL POWER SUPPLY DEVICE
La présente invention entre dans le domaine électrique, de l'alimentation d'un circuit électrique. The present invention is in the electrical field of supplying an electric circuit.
L'invention concerne particulièrement l'alternance d'alimentation d'un circuit électrique par approvisionnement depuis un réseau électrique, à savoir un réseau électrique de distribution, préférentiellement basse tension, et, en. cas de coupure, par un approvisionnement depuis un générateur électrique indépendant, telle une batterie d'accumulateurs, communément désignée « batterie », prévue rechargeable.  The invention particularly relates to alternating power supply of an electric circuit by supplying from an electrical network, namely an electrical distribution network, preferably low voltage, and, in. cutoff case, by a supply from an independent electric generator, such as a storage battery, commonly called "battery", provided rechargeable.
Un tel dispositif trouvera une application préférentielle, mais aucunement limitative, dans l'alimentation d'un circuit électrique comportant des composants lumineux, tels des « DEL » pour « Diode ElectroLuminescente (ou plus souvent dénommées « LED » en anglais) .  Such a device will find a preferential application, but in no way limiting, in the power supply of an electrical circuit comprising luminous components, such as "LEDs" for "Electro-Luminescent Diode (or more often referred to as" LED "in English).
De manière connue, de nombreux circuits sont alimentés en électricité par un réseau de distribution, tel un réseau urbain ou domestique. Afin de pallier aux sautes de tension, voire à l'arrêt complet en approvisionnement électrique, par exemple lors d'une coupure d'alimentation dudit réseau, les circuits sont connectés à une alimentation autonome, telle une batterie, par l'intermédiaire d'un composant de type relais électrique. Ainsi, lors d'une coupure d'alimentation dudit réseau, l'alimentation en électricité par la batterie remplace celle interrompue du réseau.  In known manner, many circuits are supplied with electricity by a distribution network, such as an urban or domestic network. In order to overcome the voltage surges, or even the complete shutdown in electrical supply, for example during a power failure of said network, the circuits are connected to an autonomous power supply, such as a battery, via a component of the electric relay type. Thus, during a power failure of said network, the power supply by the battery replaces the interrupted network.
On notera que ladite batterie est généralement prévue rechargeable, par l'intermédiaire dudit réseau, lors du fonctionnement normal lors de l'alimentation dudit circuit par ledit réseau.  Note that said battery is generally provided rechargeable, via said network, during normal operation during the supply of said circuit by said network.
De plus, on notera que l'alimentation par ledit réseau est généralement prévue en courant alternatif, tandis que l'alimentation par ladite batterie est prévue en courant continu. Dès lors, en entrée, le circuit comporte au moins un transformateur permettant de redresser le courant alternatif en courant continu. Ce transformateur permet notamment d'abaisser la tension et de modifier l'intensité du courant parcourant le circuit, en fonction des composants qu'il comporte. Un premier inconvénient réside dans le fait que, généralement, les composants électriques constituant le circuit de rechargement de la batterie continuent d' être alimentés par le réseau, même faiblement, lorsque la batterie a atteint son seuil maximal de rechargement, à savoir qu'elle est en pleine charge. Cet approvisionnement entraine une baisse de la durée de vie desdits composants . In addition, it will be noted that the power supply via said network is generally provided with alternating current, while the power supply by said battery is provided with direct current. Therefore, at the input, the circuit comprises at least one transformer for rectifying the alternating current in direct current. This transformer makes it possible in particular to lower the voltage and to modify the intensity of the current flowing through the circuit, according to the components that it comprises. A first disadvantage lies in the fact that, generally, the electrical components constituting the recharging circuit of the battery continue to be supplied by the network, even slightly, when the battery has reached its maximum recharging threshold, namely that it is in full charge. This supply causes a decrease in the life of said components.
Par ailleurs, lors de l'alimentation par ladite batterie, son niveau de charge diminue jusqu'à atteindre une valeur minimale, comme par exemple un voltage inférieur au voltage minimal requis pour alimenter correctement ledit circuit. Dès lors, les composants du circuit ainsi que la batterie elle-même peuvent se dégrader si l'alimentation continue avec cette valeur inférieure à celle requise.  Moreover, during the power supply by said battery, its charge level decreases until it reaches a minimum value, such as for example a voltage lower than the minimum voltage required to supply said circuit correctly. Therefore, the circuit components as well as the battery itself may degrade if the supply continues with this value less than that required.
De nombreuses solutions existent pour court-circuiter l'alimentation du circuit de rechargement par le réseau, une fois la batterie arrivée en pleine charge.  Many solutions exist to short-circuit the power supply of the recharging circuit by the network, once the battery arrives at full charge.
La présente invention consiste en une alternative aux solutions existantes et a pour but de pallier les inconvénients de l'état de la technique, en proposant un dispositif électrique constitué d'un circuit assurant l'approvisionnement en électricité de moyens lumineux par un réseau électrique ou par une batterie, par l'intermédiaire d'un relais électromagnétique. Ce dernier assure le passage du courant pour optimiser la durée de vie des composants équipant ledit circuit, améliorant la longévité de la batterie.  The present invention consists of an alternative to existing solutions and aims to overcome the disadvantages of the state of the art, by proposing an electrical device consisting of a circuit ensuring the supply of electricity to light means by an electrical network or by a battery, via an electromagnetic relay. The latter ensures the passage of current to optimize the life of the components equipping said circuit, improving the longevity of the battery.
L'invention permet aussi de changer automatiquement, de façon instantanée, l'approvisionnement en électricité, en cas de coupure, depuis le réseau vers la batterie, et inversement.  The invention also makes it possible to automatically change, instantaneously, the supply of electricity, in the event of a break, from the network to the battery, and vice versa.
Pour ce faire, le dispositif électrique selon l'invention est constitué d' un circuit pourvu de moyens lumineux et de moyens d'alimentation en électricité desdits moyens lumineux, lesdits moyens d'alimentation comprenant, d'une part, au moins une batterie rechargeable et, d'autre part, un premier et un second approvisionnements à un réseau électrique, chaque approvisionnement étant équipé d'un transformateur, ledit premier approvisionnement étant relié à ladite batterie, ledit circuit comprenant encore un relais électromagnétique . To do this, the electrical device according to the invention consists of a circuit provided with light means and power supply means of said light means, said power supply means comprising, on the one hand, at least one rechargeable battery and, on the other hand, first and second supplies to an electrical network, each supply being equipped with a transformer, said first supply being connected to said battery, said circuit further comprising an electromagnetic relay.
Ce dispositif se caractérise par le fait que ledit relais comprend :  This device is characterized in that said relay comprises:
- une première borne à laquelle sont connectés lesdits moyens lumineux ;  a first terminal to which said light means are connected;
- une deuxième borne à laquelle est connecté le second approvisionnement ;  a second terminal to which the second supply is connected;
une troisième borne à laquelle est reliée ladite batterie ;  a third terminal to which said battery is connected;
ledit relais comprenant encore un interrupteur électromagnétique dont 1 ' actionnement connecte la première borne à ladite seconde borne ou à ladite troisième borne, ledit interrupteur étant relié en un premier point à ladite batterie et en un second point audit premier approvisionnement, de sorte que :  said relay further comprising an electromagnetic switch whose actuation connects the first terminal to said second terminal or said third terminal, said switch being connected at a first point to said battery and at a second point to said first supply, so that:
- une différence de potentiels entre lesdits premier et second points induit l' actionnement dudit interrupteur depuis ladite deuxième borne vers ladite troisième borne ; et  a potential difference between said first and second points induces actuation of said switch from said second terminal to said third terminal; and
- des potentiels équivalents entre lesdits premier et second points induit l' actionnement dudit interrupteur depuis ladite troisième borne vers ladite deuxième borne.  equivalent potentials between said first and second points induces actuation of said switch from said third terminal to said second terminal.
On entend par « potentiels équivalents » des potentiels égaux ou proches, c'est-à-dire pour lesquels la différence de potentiel n'est pas suffisante pour induire 1 ' actionnement de 1 ' interrupteur électromagnétique .  Equivalent potentials are understood to mean potentials which are equal or close, ie for which the difference in potential is not sufficient to induce the actuation of the electromagnetic switch.
De plus, selon d'autres caractéristiques additionnelles, non limitatives, lesdits moyens lumineux sont constitués d'au moins une LED .  In addition, according to other additional non-limiting features, said light means consist of at least one LED.
Lesdits premier et second points peuvent être reliés par une diode empêchant la circulation du courant depuis ledit premier point vers ledit second point.  Said first and second points may be connected by a diode preventing flow of current from said first point to said second point.
Ledit dispositif peut comprendre une diode secondaire positionnée entre ladite batterie et ledit premier point, ladite diode secondaire empêchant la circulation du courant depuis ledit premier point vers ladite batterie. De façon connexe, le dispositif selon l'invention permet de préserver la batterie d'un déchargement total, préjudiciable à sa durée de vie . The device may include a secondary diode positioned between said battery and said first point, said secondary diode preventing flow of current from said first point to said battery. In a related manner, the device according to the invention makes it possible to preserve the battery from a total discharge, detrimental to its lifetime.
D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui va suivre des modes de réalisation non limitatifs de l'invention, en référence à la figure annexée , représentant un exemple de schéma électrique d'un mode préférentiel de réalisation du dispositif selon l'invention.  Other characteristics and advantages of the invention will emerge from the following detailed description of the non-limiting embodiments of the invention, with reference to the attached figure, showing an example of a circuit diagram of a preferred embodiment of the invention. device according to the invention.
La présente invention concerne un dispositif électrique 1. The present invention relates to an electric device 1.
Un tel dispositif 1 est dédié au fonctionnement de composants électriques en les alimentant en électricité, selon le cas par l'intermédiaire d'un réseau d'approvisionnement, comme un réseau domestique et, en cas de coupure de ce dernier, de façon autonome, par l'intermédiaire de moyens autonomes, comme des accumulateurs de type batterie. Such a device 1 is dedicated to the operation of electrical components by supplying them with electricity, as the case may be through a supply network, such as a home network and, in the event of the latter being cut off, autonomously. through autonomous means, such as battery-type accumulators.
Pour ce faire, ledit dispositif 1 est constitué d'un circuit. Un exemple schématisé de mise en œuvre d'un tel circuit est visible sur la figure. Ce circuit comprend des composants, connectés et reliés entre eux par des fils ou câblages assurant la circulation du courant.  To do this, said device 1 consists of a circuit. A schematic example of implementation of such a circuit is visible in the figure. This circuit comprises components, connected and interconnected by wires or cabling ensuring the flow of current.
Le dispositif 1 a pour but d'alimenter des moyens lumineux 2, en vue d'assurer l'éclairage, notamment d'une pièce d'un bâtiment, notamment au niveau d'une issue.  The purpose of the device 1 is to supply lighting means 2, with a view to ensuring lighting, in particular of a part of a building, particularly at the level of an exit.
Préférentiellement, lesdits moyens lumineux 2 sont constitués d' au moins une diode électroluminescente ou LED 3. De préférence plusieurs LED 3 sont montées en parallèle (ou en série) et s'éclairent lorsqu'elles sont alimentées en courant par ledit dispositif 1.  Preferably, said luminous means 2 consist of at least one light emitting diode or LED 3. Preferably several LEDs 3 are connected in parallel (or in series) and are illuminated when they are supplied with current by said device 1.
Selon le mode de réalisation préférentiel, lesdites LED 3 sont reliées à la masse par l'intermédiaire d'une résistance 30.  According to the preferred embodiment, said LEDs 3 are connected to ground via a resistor 30.
Outre les moyens lumineux 2, le circuit est aussi pourvu de moyens d' alimentation en électricité desdits moyens lumineux 2. Ces moyens d'alimentation comprennent deux types différents d'alimentation. D'une part, de façon autonome, lesdits moyens d'alimentation comprennent au moins une batterie 4. Cette dernière est rechargeable. In addition to the light means 2, the circuit is also provided with means for supplying electricity to said light means 2. These supply means comprise two different types of power supply. On the one hand, independently, said supply means comprise at least one battery 4. The latter is rechargeable.
D'autre part, lesdits moyens d'alimentation comprennent un premier 5 et un second 6 approvisionnements à un réseau électrique. Ce dernier fournit un courant alternatif de façon continue dans le temps, sauf en cas de coupure. C'est pourquoi chaque approvisionnement 5,6 est équipé d'un transformateur 7,8. Chaque transformateur 7,8 permet de redresser le courant et d'en abaisser la tension, voire d'en modifier l'ampérage, en fonction des composants constituant le reste du circuit, en particulier les LED 3.  On the other hand, said supply means comprise a first 5 and a second 6 supplies to an electrical network. The latter provides an alternating current continuously in time, except in case of break. That's why each 5.6 supply is equipped with a 7.8 transformer. Each transformer 7.8 is used to rectify the current and lower the voltage, or even to change the amperage, depending on the components constituting the rest of the circuit, in particular the LEDs 3.
Selon le mode de réalisation dont le circuit est schématisé, un tel transformateur comprend notamment un pont de diodes pour redresser le courant, ainsi qu'au moins un condensateur de filtrage. D'autres composants peuvent être intégrés de façon classique pour obtenir le redressement et la valeur de courant désirés .  According to the embodiment of which the circuit is schematized, such a transformer comprises in particular a diode bridge for rectifying the current, as well as at least one filtering capacitor. Other components can be integrated in a conventional manner to obtain the desired rectification and current value.
Selon un exemple de réalisation, la tension en sortie de chaque transformateur 7,8 peut être de 12 Volts (V) .  According to an exemplary embodiment, the output voltage of each transformer 7.8 may be 12 volts (V).
Comme visible sur le schéma du circuit, ledit premier approvisionnement 5 est relié à ladite batterie 4. C'est lui qui alimente la batterie 4 en vue de son rechargement. Cette alimentation peut s'effectuer par l'intermédiaire d'un régulateur temporisateur 9.  As visible in the diagram of the circuit, said first supply 5 is connected to said battery 4. It is he who feeds the battery 4 for reloading. This power supply can be performed via a timer controller 9.
On notera que la batterie 4 est reliée à une borne au niveau dudit circuit et à l'autre borne à la masse.  Note that the battery 4 is connected to a terminal at said circuit and at the other terminal to ground.
Avantageusement, ledit circuit comprend encore un relais électromagnétique 10. Ce dernier consiste en un interrupteur dont 1 ' actionnement entre une position ou une autre s'effectue en fonction de sa mise sous tension. En particulier, ledit relais 10 présente une première position initiale ou d'origine, sans contrainte , reliant deux de ses bornes .  Advantageously, said circuit further comprises an electromagnetic relay 10. The latter consists of a switch whose actuation between one position or another is effected according to its power up. In particular, said relay 10 has a first initial or unrestrained initial position connecting two of its terminals.
De plus, il comprend une seconde position contrainte, dans laquelle la liaison électrique conférée dans la première position est court-circuitée . Cette seconde position est obtenue par l'intermédiaire d'un élément interne, électromagnétique. En d'autres termes, c'est la mise sous tension dudit élément électromagnétique qui fait passer le relais 10 depuis sa première position vers sa seconde position. Inversement, si ledit élément électromagnétique n'est plus alimenté, alors le relais 10 revient dans sa première position d' origine . In addition, it comprises a second constrained position, in which the electrical connection conferred in the first position is short-circuited. This second position is obtained via an internal element, electromagnetic. In other words, it is the energization of said electromagnetic element that passes the relay 10 from its first position to its second position. Conversely, if said electromagnetic element is no longer powered, then relay 10 returns to its first original position.
L'avantage d'un tel relais électromagnétique 10 réside dans le fait que le changement d'une position vers une autre s'effectue en fonction de l'alimentation en courant, permettant ainsi de court-circuiter l'une ou l'autre de ses alimentations, en fonction du courant circulant réellement dans le circuit.  The advantage of such an electromagnetic relay 10 lies in the fact that the change from one position to another is effected as a function of the power supply, thus making it possible to short-circuit one or the other of its power supplies, depending on the current actually flowing in the circuit.
Ainsi, le relais 10 comprend :  Thus, the relay 10 comprises:
- une première borne 11 à laquelle sont connectés lesdits moyens lumineux 2 ;  a first terminal 11 to which said light means 2 are connected;
- une deuxième borne 12 à laquelle est connecté le second approvisionnement 6 ;  a second terminal 12 to which the second supply 6 is connected;
- une troisième borne 13 à laquelle est reliée ladite batterie 4.  a third terminal 13 to which said battery 4 is connected.
En particulier, comme visible sur le schéma, le relais 10 permet, en passant d'une position à une autre, d'alimenter la première borne 11 soit par la batterie 4, soit par ledit second approvisionnement 6, relié au réseau électrique, comme un réseau domestique .  In particular, as can be seen in the diagram, the relay 10 makes it possible, by passing from one position to another, to supply the first terminal 11 either by the battery 4 or by said second supply 6, connected to the electrical network, as a home network.
Plus particulièrement, en position initiale, non contraint, lorsque l'élément électromagnétique n'est pas sollicité, alors ledit relais 10 connecte la première borne 11 à la deuxième borne 12. A l'inverse, lorsqu'il est sollicité, cet élément électromagnétique déconnecte la deuxième borne 12 , pour relier la première borne 11 à la troisième borne 13.  More particularly, in the initial position, unconstrained, when the electromagnetic element is not biased, then said relay 10 connects the first terminal 11 to the second terminal 12. In contrast, when it is stressed, this electromagnetic element disconnects the second terminal 12, to connect the first terminal 11 to the third terminal 13.
En d'autres termes, ledit relais 10 comprend encore un interrupteur électromagnétique 14 dont 1 ' actionnement connecte la première borne 11 à ladite seconde borne 12 ou à ladite troisième borne 13.  In other words, said relay 10 further comprises an electromagnetic switch 14 whose actuation connects the first terminal 11 to said second terminal 12 or to said third terminal 13.
De plus, ledit interrupteur 14 est relié en un premier point 15 à ladite batterie 4 et en un second point 16 audit premier approvisionnement 5, de sorte que : - une différence de potentiels entre lesdits premier 15 et second 16 points induit l' actionnement dudit interrupteur 14 depuis ladite deuxième borne 12 vers ladite troisième borne 13 ; et In addition, said switch 14 is connected at a first point 15 to said battery 4 and at a second point 16 to said first supply 5, so that: a potential difference between said first 15 and second 16 points induces the actuation of said switch 14 from said second terminal 12 to said third terminal 13; and
- des potentiels équivalents entre lesdits premier 15 et second 16 points induit l' actionnement dudit interrupteur 14 depuis ladite troisième borne 13 vers ladite deuxième borne 12.  equivalent potentials between said first 15 and second 16 points induces actuation of said switch 14 from said third terminal 13 to said second terminal 12.
On notera que ce dernier actionnement peut consister en un retour automatique, par exemple sous l'effet de moyens de rappel élastique, vers la position initiale dans laquelle ledit interrupteur 14 n'est pas sollicité. Ces moyens de rappel élastique peuvent être constitués par une lame métallique élastique .  Note that the latter actuation may consist of an automatic return, for example under the effect of elastic return means, to the initial position in which said switch 14 is not biased. These elastic return means may be constituted by an elastic metal blade.
Plus précisément, l'invention fait intervenir la différence de potentiels électriques entre les points 15 et 16 du circuit. S'il existe une différence entre ces potentiels, alors l'interrupteur électromagnétique est parcouru par un courant, induisant 1 ' actionnement et le passage dans la position dans laquelle les LED 3 sont alimentées par la batterie 4. Une telle différence de potentiels entre les points 15 et 16 intervient lorsque le premier approvisionnement 5 ne fournit plus de courant, en cas de coupure. Il y a donc un potentiel égal à 0 V au niveau du second point 16. Dès lors, seule la batterie 4 fournit du courant, induisant un potentiel positif au niveau du premier point 15.  More specifically, the invention involves the difference of electrical potentials between points 15 and 16 of the circuit. If there is a difference between these potentials, then the electromagnetic switch is traversed by a current, inducing one actuation and the passage in the position in which the LEDs 3 are powered by the battery 4. Such a potential difference between the points 15 and 16 occurs when the first supply 5 no longer provides power, in case of failure. There is therefore a potential equal to 0 V at the second point 16. Therefore, only the battery 4 provides current, inducing a positive potential at the first point 15.
A l'inverse, si le courant circule depuis le premier approvisionnement 5, alors le second point 16 présente un potentiel maximal (équivalent à 12 V dans l'exemple préférentiel de réalisation) . Le premier point 15 est lui aussi alimenté par la batterie à un potentiel équivalent, de sorte que l'interrupteur 14 n'est pas sollicité.  Conversely, if the current flows from the first supply 5, then the second point 16 has a maximum potential (equivalent to 12 V in the preferred embodiment). The first point 15 is also powered by the battery at an equivalent potential, so that the switch 14 is not biased.
De plus, de façon additionnelle, lesdits premier 15 et second 16 points sont reliés par une diode 17 empêchant la circulation du courant depuis ledit premier point 15 vers ledit second point 16. Cette diode 17 permet en sens inverse de faire passer le courant et, de ce fait, d'approvisionner le premier point 15, si la tension fournie par la batterie 4 est inférieure à la tension fournie par le premier approvisionnement 5. Par exemple, si la batterie 4 n'est pas totalement chargée, alors c'est le réseau électrique via le premier approvisionnement 5 qui va alimenter chaque point 15 et 16 de l'interrupteur 14, avec une même valeur de potentiel électrique. L'interrupteur 14 ne sera alors pas sollicité. Moreover, additionally, said first 15 and second 16 points are connected by a diode 17 preventing the flow of current from said first point 15 to said second point 16. This diode 17 allows in the opposite direction to make passing the current and, thereby, supply the first point 15, if the voltage supplied by the battery 4 is less than the voltage supplied by the first supply 5. For example, if the battery 4 is not fully charged then it is the power grid via the first supply 5 which will supply each point 15 and 16 of the switch 14, with the same value of electric potential. The switch 14 will not be solicited.
De plus, ladite diode 17 sert de limitation contre les hautes ou surtensions ou les pics de courant.  In addition, said diode 17 serves as a limitation against high or overvoltages or current peaks.
De façon connexe, ledit dispositif 1 peut comprendre une diode secondaire 18 positionnée entre ladite batterie 4 et ledit premier point 15. Cette diode secondaire 18 empêche la circulation du courant depuis ledit premier point 15 vers ladite batterie 4. Comme visible sur le schéma, elle se trouve en amont du côté de la batterie 4 par rapport à la diode 17. Ainsi, le courant provenant du premier approvisionnement 5 ne peut pas remonter vers la batterie 4.  In a related manner, said device 1 may comprise a secondary diode 18 positioned between said battery 4 and said first point 15. This secondary diode 18 prevents the flow of current from said first point 15 to said battery 4. As shown in the diagram, it is located upstream of the battery side 4 with respect to the diode 17. Thus, the current from the first supply 5 can not go back to the battery 4.
De même, une autre diode secondaire 19 peut être positionnée entre le premier approvisionnement 5, en particulier au niveau d' une des sorties de son transformateur 7, et le second point 16 de l'interrupteur 14 du relais 10. Cette autre diode secondaire 19 empêche le courant de circuler depuis la batterie 4, via ledit interrupteur 14 jusqu' audit premier approvisionnement 5.  Similarly, another secondary diode 19 may be positioned between the first supply 5, in particular at one of the outputs of its transformer 7, and the second point 16 of the switch 14 of the relay 10. This other secondary diode 19 prevents the current from circulating from the battery 4, via said switch 14 until said first supply 5.
En outre, une résistance supplémentaire 20 peut être positionnée pour relier le second point 16 à la masse. Une telle résistance peut avoir une valeur de 150 Ohms (Ω) .  In addition, an additional resistor 20 may be positioned to connect the second point 16 to ground. Such a resistor may have a value of 150 ohms (Ω).
Par ailleurs, le circuit spécifique du dispositif électrique 1 permet de limiter la dégradation de la batterie. En effet, lorsque le premier approvisionnement 5 est coupé et que le second point 16 présente un potentiel nul, alors c'est la batterie 4 qui alimente l'interrupteur 14, l'activant vers la position dans laquelle la première borne 11 est connectée à la troisième borne 13, de sorte que ce soit ladite batterie 4 qui alimente les LED 3. Dans ce contexte, si la tension de la batterie 4 diminue, arrivée en dessous d'un certain voltage, la différence de potentiel entre les premier 15 et second 16 points de l'interrupteur 14 n'est plus suffisante pour permettre sa sollicitation. Il revient alors en position d'origine, coupant automatiquement l'alimentation par la batterie 4. Moreover, the specific circuit of the electrical device 1 makes it possible to limit the degradation of the battery. Indeed, when the first supply 5 is cut and the second point 16 has a zero potential, then it is the battery 4 which supplies the switch 14, activating it to the position in which the first terminal 11 is connected to the third terminal 13, so that it is said battery 4 which supplies the LEDs 3. In this context, if the voltage of the battery 4 decreases below a certain voltage, the potential difference between the first 15 and second 16 points of the switch 14 is no longer sufficient to allow its solicitation. It then returns to its original position, automatically switching off the power supply via the battery 4.
Cette coupure automatique assure que la batterie 4 préserve un niveau minimum de charge , évitant son déchargement total et sa détérioration.  This automatic shutdown ensures that the battery 4 preserves a minimum level of charge, avoiding its total discharge and its deterioration.
Ainsi, le dispositif électrique 1 selon l'invention permet que la majorité des composants du circuit de la batterie ne sont pas sollicités pendant une phase d' alimentation par un réseau, à savoir sur « secteur ». De plus, en cas de panne de l'un ou l'autre des composants, sauf le transformateur 7 du second approvisionnement 6, les LED 3 sont toujours alimentées.  Thus, the electrical device 1 according to the invention allows that the majority of the circuit components of the battery are not solicited during a supply phase by a network, namely on "sector". In addition, in case of failure of one or the other of the components, except the transformer 7 of the second supply 6, the LEDs 3 are always powered.
