Description

Variateur pour 2 lampes de puissances différentes Dimmer for 2 lamps of different wattages
La présente invention concerne les circuits variateurs de puissance, notamment les circuits variateurs de lumière utilisés pour la commande de l'intensité lumineu¬ se des lampes à incandescence telles ' que les lampes halogè- nés .The present invention relates to servo amplifier circuits, including dimmer circuits used to control the intensity lumineu¬ are incandescent lamps such 'as halogenated lamps born.
Traditionnellement à chaque circuit variateur est associé un boîtier de commande, généralement placé au sol . La variation de l'intensité lumineuse est obtenue par action sur un curseur relié à un potentiomètre . Le but de la présente invention est de propo¬ ser un double circuit variateur de puissance capable de com¬ mander , par l'intermédiaire de deux curseurs du type précité, l'intensité lumineuse de deux lampes à incandes¬ cence . La présente invention a donc pour objet un circuit variateur de puissance, caractérisé en ce qu'il est associé à deux curseurs montés chacun sur un potentiomètre et destinés à commander respectivement chacun une charge par l'intermédiaire d'au moins un sous-circuit commun, ledit circuit variateur de puissance étant associé à deux phases alimentant simultanément lesdites charges.Un tel sous-circuit commun est avantageusement un sous-circuit d1 antiparasitage radiofréquence du type RLC.Traditionally, each control circuit is associated with a control unit, generally placed on the ground. The variation of the light intensity is obtained by action on a cursor connected to a potentiometer. The object of the present invention is to provide a double power variator circuit capable of controlling, by means of two sliders of the aforementioned type, the light intensity of two incandescent lamps. The present invention therefore relates to a power variator circuit, characterized in that it is associated with two sliders each mounted on a potentiometer and intended to control each a load respectively by means of at least one common sub-circuit. , said power drive circuit being associated with two phases simultaneously feeding said charges.Un such subcircuit joint is preferably a subcircuit of one radio frequency suppression of the RLC.
De préférence, une charge est montée entre les deux phases en étant reliée à l'une d'elle par l'intermédiaire d'un triac commandé par un circuit déphas- deur comportant un potentiomètre associé à au moins un élé¬ ment capacitif . Les deux charges peuvent être reliées chacune par l'intermédiaire d'un triac commandé par un cir- cuit dephaseur à une même phase, lesdites charges étant alors chacune reliée , par exemple, directement ou par l'intermédiaire d'un fusible à l'autre des deux phases.Preferably, a load is mounted between the two phases by being connected to one of them by means of a triac controlled by a phase shifting circuit comprising a potentiometer associated with at least one capacitive element. The two loads can each be connected by means of a triac controlled by a phase-shifting circuit with the same phase, said loads then being each connected, for example, directly or by means of a fuse with the other of the two phases.
Un diac peut être monté entre un point d'un circuit dephaseur et la gâchette du triac que commande ledit circuit dephaseur. Une diode Zener peut être montée en série avec un élément diac. De préférence encore, une charge est une lampe à incandescence , notamment du type halogène. En particulier chaque charge peut" être une lampe, l'une étant une lampe moyenne puissance, l'autre étant une lampe basse puissance (tension de sécurité) associée à un élément abaisseur de tension .L' élément abaisseur de tension peut être un trans¬ formateur de 220 volts/ 6-12 ou 24 volts suivant le type de lampe, d'une puissance d'environ 50 watts, ou un circuit convertisseur ,1a lampe moyenne puissance étant une lampe de 220 volts d'une puissance d'environ 500 watts.A diac can be mounted between a point on a phase shifting circuit and the trigger of the triac that is controlled by said phase shifting circuit. A Zener diode can be connected in series with a diac element. More preferably, a load is an incandescent lamp, in particular of the halogen type. In particular each load can " be a lamp, one being a medium power lamp, the other being a low power lamp (safety voltage) associated with a step-down element. The step-down element can be a trans ¬ 220 volt / 6-12 or 24 volt trainer depending on the type of lamp, with a power of about 50 watts, or a converter circuit, the medium power lamp being a 220 volt lamp with a power of about 500 watts.
D'autres caractéristiques et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée d'un exemple de réalisation, faite en référence à la figure annexée unique, qui représente le schéma d'un circuit variateur de puissance mettant en oeuvre les enseignements de la présente invention.Other characteristics and advantages of the present invention will appear better on reading the detailed description of an exemplary embodiment, made with reference to the single appended figure, which represents the diagram of a power variator circuit implementing the teachings of the present invention.
Sur cette figure, les éléments d'indice com¬ pris entre 1 et 10 sont communs aux deux montages, les élé¬ ments d'indice compris entre 11 et 30 sont relatifs au montage basse puissance, les éléments d'indice supérieur à 30 sont relatifs au montage moyenne puissance. Analyse du circuit basse puissance.In this figure, the elements of index included between 1 and 10 are common to the two assemblies, the elements of index between 11 and 30 relate to the low power assembly, the elements of index greater than 30 are relating to medium power assembly. Analysis of the low power circuit.
La charge référencée (11) est placée au se¬ condaire d'un transformateur (12) 220/6 - 12 ou 24 volts suivant le type de lampe puissance environ 50 watts. Un fu¬ sible (13) facultatif peut être inséré en série dans ce cir¬ cuit . Le primaire du transformateur est alimenté par les deux phases (1) et (1* ) . La phase (1) étant reliée à la charge par l'intermédiaire d'un fusible (13) tandis que la phase (1' ) est reliée avec interposition d'une self (4) et d'un triac (14), le triac (14) est commandé en phase par un circuit dephaseur comprenant en série un élément résistif (15,16) composé d'une résistance fixe (15) (par exemple 120 ohms ) et d'une résistance variable (16) (par exemple va- riant de O à 270 kilos ohms) qui est couplée à l'interrup- eur (17) qui est alors un interrupteur fin de course cor¬ respondant à la position de résistance maximale .L' interrup¬ teur est facultatif - la Zener (20) ayant un rôle similaire La résistance fixe (15) est choisie de manière à limiter le courant de gâchette du triac au moment de l'amorçage de celui-ci .The load referenced (11) is placed in the second of a transformer (12) 220/6 - 12 or 24 volts depending on the type of lamp power about 50 watts. An optional fuse (13) can be inserted in series in this cooked circuit. The transformer primary is supplied by the two phases (1) and (1 *). The phase (1) being connected to the load via a fuse (13) while the phase (1 ') is connected with the interposition of a choke (4) and a triac (14), the triac (14) is phase controlled by a phase shifter circuit comprising in series a resistive element (15,16) composed of a fixed resistor (15) (for example 120 ohms) and a variable resistor (16) (for example varying from O to 270 kilos ohms) which is coupled to the interrup- eur (17) which is then a limit switch corresponding to the position of maximum resistance. The switch is optional - the Zener (20) having a similar role The fixed resistance (15) is chosen so as to limit the trigger current of the triac when it is primed.
Le circuit dephaseur comporte, associé à l'élément résistif (15,16) un élément capacitif (21) (par exemple un condensateur de 0,12 micro Farad) monté en série avec une résistance fixe (22) de sorte que le point milieu (18) entre l'élément résistif et l'élément capacitif va pré¬ senter un déphasage variable par rapport aux électrodes de puissance Al, A2 du triac permettant ainsi de retarder l'amorçage de celui-ci par rapport au début de chaque demi période et de moduler ainsi la puissance délivrée au primai¬ re du transformateur (12).The phase shifting circuit comprises, associated with the resistive element (15,16) a capacitive element (21) (for example a 0.12 micro Farad capacitor) connected in series with a fixed resistor (22) so that the midpoint (18) between the resistive element and the capacitive element will present a variable phase shift relative to the power electrodes Al, A2 of the triac thus making it possible to delay the initiation of the latter relative to the start of each half period and thus modulate the power delivered to the primary transformer (12).
De façon en elle-même connue, la liaison entre le point milieu (18) du circuit dephaseur RC et la gâchette G du triac est réalisée par l'intermédiaire d'un diac (19) permettant de générer des pics de courant assurant un meil¬ leur amorçage du triac.In a manner known per se, the connection between the midpoint (18) of the phase shifting circuit RC and the trigger G of the triac is carried out by means of a diac (19) making it possible to generate current peaks ensuring a better ¬ their priming of the triac.
De préférence , on prévoit également sur le circuit de gâchette, en série avec le diac, une diode Zener (20) (par exemple une diode à 12 V environ), qui assure une extinction complète de la charge même si la valeur maximale réelle de résistance de la résistance variable (16) (par exemple 470 kilos ohms) est inférieure à la valeur nominale (par exemple 500 kilos ohms) pour laquelle le circuit a été calculé ; on pallie ainsi les conséquences des dispersions dans les caractéristiques de fabrication des résistances va¬ riables, dispersions qui peuvent être importantes.Preferably, there is also provided on the trigger circuit, in series with the diac, a Zener diode (20) (for example a diode at about 12 V), which ensures complete extinction of the load even if the actual maximum value of resistance of the variable resistor (16) (for example 470 kilos ohms) is less than the nominal value (for example 500 kilos ohms) for which the circuit has been calculated; the consequences of dispersions in the manufacturing characteristics of the variable resistances are thus overcome, dispersions which can be significant.
Un circuit d' antiparasitage radiofréquence est inclus . Il comporte une inductance (4) en série avec le triac (14) et le primaire du transformateur (12) associée à deux réseaux RC, montés en parallèle sur la branche formée par l'inductance (4) et le triac (14) dont l'un est monté en série (25,26) et l'autre en parallèle (23) (24).

La résistance (33) est choisie de manière à limiter le courant de gâchette du triac au moment de l'amorçage de celui-ci.The load (31) is here directly supplied by the two phases (1) and (l 1 ) via the triac (32).

The resistor (33) is chosen so as to limit the trigger current of the triac when it is primed.
Le circuit dephaseur comporte, associé à l'élément résistif (33,34) un élément capacitif (35) (par exemple un condensateur de 0,1 micro Farad). Le point milieu (36) va présenter un déphasage variable par rapport _ aux électrodes de puissance du triac, permettant ainsi de retar¬ der l'amorçage de celui-ci par rapport au début de chaque demi-période et de moduler ainsi la puissance délivrée à la charge (31).The phase shifting circuit comprises, associated with the resistive element (33,34) a capacitive element (35) (for example a capacitor of 0.1 micro Farad). The midpoint (36) will have a variable phase shift with respect to the power electrodes of the triac, thus making it possible to delay the initiation of the latter relative to the start of each half-period and thus to modulate the power delivered chargeable (31).
