Description

La présente invention concerne un système de variation de puissance dans un circuit électrique comprenant une ou plusieurs lampes électriques. Le présent dispositif a pour but de faire varier la puissance d'éclairage en fonction de paramètres tels que l'heure ou la luminosité extérieure. Il est notamment destiné à commander un réseau d'éclairage public ou un réseau d'éclairage dans les ateliers.The present invention relates to a power variation system in an electrical circuit comprising one or more electric lamps. The purpose of this device is to vary the lighting power as a function of parameters such as the time or the external brightness. It is especially intended to control a public lighting network or a lighting network in workshops.

On connait des dispositifs destinés à faire varier la puissance de lampes mettant en oeuvre des variateurs électromécaniques tels que des rhéostats ou des transformateurs toriques. On connaît également des variateurs électroniques utilisant des triacs.Devices are known for varying the power of lamps using electromechanical dimmers such as rheostats or toroidal transformers. Electronic variators are also known using triacs.

Ces dispositifs présentent un certain nombre d'inconvénients:
   les variateurs électromécaniques peuvent avoir dans certains cas un rendement faible et être générateurs de parasites électromagnétiques. De plus, ils nécessitent un système de motorisation asservie complexe pour réagir à des paramètres extérieurs. Les variateurs électroniques sont d'autre part sensibles aux perturbations du réseau, notamment aux surtensions pouvant apparaître lors d'un orage.These devices have a number of drawbacks:
electromechanical drives can in some cases have a low efficiency and generate electromagnetic interference. In addition, they require a complex servo motor system to react to external parameters. Electronic variators are also sensitive to network disturbances, in particular to overvoltages which may appear during a thunderstorm.

Mais, outre les inconvénients cités ci-dessus, les dispositifs connus ne conviennent pas pour certains types de lampes nécessitant obligatoirement une puissance maximale à l'allumage. Ceci est notamment le cas pour certaines lampes du type à vapeur métalliques telles que les lampes au sodium ou les lampes au mercure stabilisées par des appareillages standard.However, in addition to the drawbacks mentioned above, the known devices are not suitable for certain types of lamps which necessarily require maximum power on ignition. This is particularly the case for certain lamps of the metal vapor type such as sodium lamps or mercury lamps stabilized by standard devices.

Ainsi, le brevet français FR-1378274 propose un appareil utilisant un autotransformateur et un commutateur pour obtenir l'atténuation de l'intensité lumineuse, en réduisant la tension d'alimentation de la, ou des lampes alimentées, indépendamment des lampes à atténuer. Ce type d'appareil est inutilisable pour faire varier l'intensité des lampes à décharge.Thus, French patent FR-1378274 proposes an apparatus using an autotransformer and a switch to obtain attenuation of the light intensity, by reducing the supply voltage of the, or of the lamps supplied, independently of the lamps to be attenuated. This type of device cannot be used to vary the intensity of discharge lamps.

La présente invention a pour but de remédier à cet inconvénient en assurant une puissance maximale sur le réseau au moment de l'allumage et pendant une durée suffisante pour que les lampes atteignent leur régime de fonctionnement et ceci quelles que soient les valeurs des paramètres d'asservissement.The present invention aims to remedy this drawback by ensuring maximum power on the network at the time of ignition and for a sufficient time for the lamps reach their operating speed, regardless of the values of the control parameters.

La présente invention présente de nombreux autres avantages. Notamment le dispositif selon l'invention est très peu sensible aux perturbations du réseau, ne crée pas de parasites électromagnétiques et a un bon rendement. De plus, étant réalisé avec des composants standard, il est d'un coût réduit et d'une grande fiabilité.The present invention has many other advantages. In particular, the device according to the invention is very insensitive to disturbances from the network, does not create electromagnetic interference and has good performance. In addition, being produced with standard components, it is of low cost and high reliability.

D'autres avantages et caractéristiques ressortiront mieux à la lecture de la description qui va suivre et qui expose un mode particulier de réalisation donné à titre indicatif et non limitatif.

  • La figure 1 représente un schéma synoptique du dispositif.
  • le dispositif comprend deux inverseurs électromagnétiques 5(1) et (2) et deux inverseurs (3) et (4) commandés par une horloge ainsi qu'un transformateur injecteur (5) et un temporisateur (6), d'une période égale à la durée nécessaire aux lampes pour atteindre leur régime de fonctionnement, soit de 5 à 10 secondes pour les lampes tubes à starter et d'environ 1 minute pour les lampes du type à sodium haute pression (SHP) et les lampes à mercure.
  • L'injecteur (5) est constitué d'un transformateur dont l'enroulement secondaire (7) est inséré dans la phase du réseau d'éclairage et dont l'enroulement primaire (8) possède deux prises intermédiaires (8a,8b).
  • L'inverseur (1) est placé entre le contact commun (10) de l'inverseur (2) d'une part et les prises intermédiaires (8a, 8b) de l'enroulement primaire (8) d'autre part.
Other advantages and characteristics will emerge more clearly on reading the description which follows and which sets out a particular embodiment given by way of indication and without limitation.
  • Figure 1 shows a block diagram of the device.
  • the device comprises two electromagnetic inverters 5 (1) and (2) and two inverters (3) and (4) controlled by a clock as well as an injector transformer (5) and a timer (6), with a period equal to the time required for the lamps to reach their operating speed, namely from 5 to 10 seconds for tube choke lamps and approximately 1 minute for high pressure sodium (SHP) type lamps and mercury lamps.
  • The injector (5) consists of a transformer whose secondary winding (7) is inserted in the lighting network phase and whose primary winding (8) has two intermediate sockets (8a, 8b).
  • The inverter (1) is placed between the common contact (10) of the inverter (2) on the one hand and the intermediate taps (8a, 8b) of the primary winding (8) on the other.

Lorsque l'enroulement primaire est mis en court-circuit, le réseau est alimenté à sa puissance maximale.When the primary winding is short-circuited, the network is supplied at its maximum power.

Cela se produit lorsque la bobine (9) de l'inverseur électromagnétique (2) est excitée et ferme le contact (10).This occurs when the coil (9) of the electromagnetic inverter (2) is energized and closes the contact (10).

La bobine (9) de l'inverseur (2) est commandée par le temporisateur (6). Lors de la mise sous tension du réseau, le temporisateur (6) établit un contact fugitif entre le point (11) et la phase. Ce contact est maintenu pendant une durée réglable et déterminée par les caractéristiques des lampes utilisées sur le réseau d'éclairage. Elle peut être fixée à titre d'exemple à 120 secondes pour des lampes du type SHP.The coil (9) of the inverter (2) is controlled by the timer (6). When the network is powered up, the timer (6) establishes a fugitive contact between the point (11) and the phase. This contact is maintained for an adjustable duration and determined by the characteristics of the lamps used on the lighting network. It can be set by way of example at 120 seconds for SHP type lamps.

Après ce délai, le temporisateur revient à sa position de repos et assure un contact entre la phase et le point (12).After this delay, the timer returns to its rest position and ensures contact between the phase and the point (12).

Le point (12) est d'autre part relié à l'inverseur (4) qui peut être commandé par une horloge mécanique ou électronique.The point (12) is also connected to the inverter (4) which can be controlled by a mechanical or electronic clock.

Cet inverseur (4) alimente la bobine (13) ou la bobine (9) de l'inverseur électromagnétique (2) selon sa position.This inverter (4) supplies the coil (13) or the coil (9) of the electromagnetic inverter (2) depending on its position.

Lorsque la bobine (9) est excitée, l'enroulement secondaire de l'injecteur (5) est mis en court-circuit et le réseau est donc alimenté à sa puissance maximale. Lorsque la bobine (13) est excitée, la puissance disponible sur le réseau peut prendre deux valeurs selon l'état de l'inverseur (3). Cet inverseur (3) pouvant également être commandé par une pendule, alimente la bobine (14) ou (15) de l'inverseur électromagnétique (1).When the coil (9) is energized, the secondary winding of the injector (5) is short-circuited and the network is therefore supplied at its maximum power. When the coil (13) is energized, the power available on the network can take two values depending on the state of the inverter (3). This inverter (3) can also be controlled by a pendulum, feeds the coil (14) or (15) of the electromagnetic inverter (1).

Lorsque la bobine (14) est excitée, la prise intermédiaire de l'injecteur est alimentée et lorsque la bobine (15) est excitée, la prise extrême (16) de l'injecteur (5) est alimentée.When the coil (14) is energized, the intermediate plug of the injector is supplied and when the coil (15) is energized, the end plug (16) of the injector (5) is supplied.

Il est ainsi possible de faire varier la puissance du réseau d'éclairage en fonction de l'état des inverseurs (3) et (4) selon le tableau suivant :

Figure imgb0001
It is thus possible to vary the power of the lighting network according to the state of the inverters (3) and (4) according to the following table:
Figure imgb0001

Ce tableau n'est bien entendu valable que lorsque le temporisateur est en position de repos (12). Lorsque le temporisateur (6) est en position fugitive de travail (11), la puissance disponible sur le réseau d'éclairage est maximale quelles que soient les positions des inverseurs (3 et 4).This table is of course only valid when the timer is in the rest position (12). When the timer (6) is in the fugitive working position (11), the power available on the lighting network is maximum regardless of the positions of the reversers (3 and 4).

Dans ce qui va suivre, on donnera quelques exemples non limitatifs de variantes.In what follows, we will give some nonlimiting examples of variants.

Selon une première variante, le dispositif peut comporter un injecteur disposant de plusieurs prises intermédiaires.According to a first variant, the device may include an injector having several intermediate sockets.

Il est ainsi possible d'ajuster les puissances intermédiaires et minimales du réseau d'éclairage.It is thus possible to adjust the intermediate and minimum powers of the lighting network.

Selon une seconde variante, on insère un deuxième injecteur entre l'inverseur électromagnétique (1) et l'inverseur électromagnétique (2).According to a second variant, a second injector is inserted between the electromagnetic inverter (1) and the electromagnetic inverter (2).

Ce deuxième injecteur permet d'ajuster finement les valeurs minimales et intermédiaires.This second injector allows fine adjustment of the minimum and intermediate values.

Selon une autre variante, un des inverseurs (3, 4) ou les deux, peuvent être commandés par des dispositifs sensibles à l'éclairage extérieur.According to another variant, one or both of the reversers (3, 4) can be controlled by devices sensitive to external lighting.

A titre d'exemple, dans le cas d'éclairage d'ateliers, l'inverseur (4) peut être constitué d'une cellule photoélectrique commandant un relais électromagnétique ou électronique dont le seuil de déclenchement correspondra à la tombée du jour. L'inverseur (3) peut également être constitué d'une cellule photoélectrique commandant un relais dont le seuil de déclenchement correspondra à une luminosité supérieure, afin de moduler l'éclairage en fonction de la luminosité extérieure.For example, in the case of workshop lighting, the inverter (4) may consist of a photoelectric cell controlling an electromagnetic or electronic relay whose triggering threshold will correspond to dusk. The inverter (3) can also consist of a photoelectric cell controlling a relay, the triggering threshold of which will correspond to a higher luminosity, in order to modulate the lighting as a function of the external luminosity.

Une autre variante consiste à remplacer les inverseurs électromagnétiques (1) et (2) par des inverseurs triphasés afin de commander un réseau triphasé.Another variant consists in replacing the electromagnetic inverters (1) and (2) with three-phase inverters in order to control a three-phase network.

De nombreux autres modes de réalisation peuvent être envisagés sans pour autant sortir du champ de la présente invention.Many other embodiments can be envisaged without departing from the scope of the present invention.
