Description

La présente invention concerne un dispositif d'éclairage électrique comportant un tube contenant un gaz ionisable.The present invention relates to a lighting device electric comprising a tube containing an ionizable gas.

Les systèmes d'allumage et régulation des tubes à décharge gazeuse, tels que les tubes fluorescents, sont en général composés de transformateurs et ballasts à bobine et noyau magnétiques présentant de fortes fuites magnétiques, des inductances en séries, des starters ou des filaments chauffés pour permettre l'amorçage des tubes et en réguler l'intensité.Ignition systems and regulation of discharge tubes gas, such as fluorescent tubes, are generally composed of magnetic coil and core transformers and ballasts with strong magnetic leaks, inductors in series, starters or filaments heated to allow priming the tubes and regulating the intensity.

Ils peuvent aussi comporter des fils chauffants et résistances ou encore utiliser des ballasts électroniques haute fréquence, multiplicateurs de tension pour permettre l'amorçage. Ces éléments présentent divers inconvénients tels que poids et encombrement relativement élevés des circuits de stabilisation d'allumage, important échauffement des systèmes selfiques, parasitage et pollution des lignes de courant.They can also include heating wires and resistors or use high electronic ballasts frequency, voltage multipliers to allow priming. These elements have various disadvantages such as weight and relatively large dimensions of the stabilization circuits ignition, significant heating of the inductive systems, interference and pollution of power lines.

De tels systèmes sont le plus souvent lourds et encombrants, limitant, de ce fait, les possibilités du concepteur lumièreSuch systems are most often heavy and bulky, thereby limiting the possibilities of the lighting designer

La demande de brevet français 87 07146 décrit un dispositif, doubleur de tension en continu, adapté aux extrémités du tube et en permettant l'allumage sans ballast ou starter.French patent application 87 07146 describes a device, continuous voltage doubler, adapted to the ends of the tube and allowing ignition without ballast or choke.

La demande de brevet français 89 04356 décrit un dispositif doubleur de tension équipé d'un commutateur inversant la polarité de la tension aux bornes du tube de sorte à éviter la dissymétrie de fonctionnement, cause d'un vieillissement prématuré du tube.French patent application 89 04356 describes a device voltage doubler fitted with a polarity reversing switch of the voltage across the tube so as to avoid asymmetry due to premature aging of the tube.

L'état de la technique peut également être défini par le document US-A-4.092.562 qui concerne une lampe comprenant un tube fluorescent, une résistance de charge, des moyens de starter et des connections terminales pour connecter une pluralité de lampes ensemble.The state of the art can also be defined by the document US-A-4,092,562 which relates to a lamp comprising a tube fluorescent, load resistance, choke means and terminal connections for connecting a plurality of lamps together.

Ce système, bien que moins encombrant, utilise encore, d'une part une résistance de charge et d'autre part des moyens de starter. Aucun élément combinant ces deux fonctions n'est utilisé, ce qui permettrait de diminuer encore les coûts de fabrication et l'encombrement de la lampe ainsi équipée.This system, although less bulky, still uses a firstly a load resistance and secondly means of starter. No element combining these two functions is used, which would further reduce manufacturing costs and the size of the lamp thus equipped.

La présente invention a pour objet un dispositif combinant les fonctions d'aide à l'allumage et de régulation des tubes à gaz, de faible encombrement et de poids réduit, permettant une conception plus libre des luminaires d'éclairage et des systèmes producteurs de lumière comportant un tube fluorescent et un système d'aide à l'allumage et de régulation intégré.The present invention relates to a device combining the ignition assistance and regulation functions of the tubes gas, compact and light weight, allowing freer design of lighting fixtures and systems light producers comprising a fluorescent tube and a integrated ignition and regulation system.

Ce dispositif d'allumage selon l'invention est notamment remarquable en ce qu'il utilise les caractéristiques de résistivité et d'adaptabilité de fabrication des polymères chargés.This ignition device according to the invention is in particular remarkable in that it uses the characteristics of resistivity and adaptability of polymer manufacturing loaded.

A cet effet, la présente invention propose un dispositif d'aide à l'allumage et de régulation pour tubes fluorescents, tels qu'un tube à décharge gazeuse alimentée via deux électrodes par un circuit électrique, chaque électrode étant située à l'une des extrémités du tube, caractérisé par le fait que le circuit électrique comporte une pièce en polymère chargé, cette pièce étant positionnée à proximité dudit tube, et que ladite pièce en polymère chargé fait office de ballast pour le tube avec des fonctions d'aide à l'amorçage et de régulation du fonctionnement correct dudit tube.To this end, the present invention provides a device ignition aid and regulation for fluorescent tubes, such that a gas discharge tube supplied via two electrodes by an electrical circuit, each electrode being located at one of ends of the tube, characterized in that the circuit electric has a charged polymer part, this part being positioned close to said tube, and said part in charged polymer acts as ballast for the tube with start-up assistance and operating regulation functions correct of said tube.

Au moins l'une des électrodes est couplée avec un condensateur et un ensemble diode-résistance ayant pour fonction d'amorcer plus facilement la décharge et de réguler la brillance du tube par l'intermédiaire du polymère chargé.At least one of the electrodes is coupled with a capacitor and a diode-resistor assembly having the function more easily initiate discharge and regulate gloss of the tube through the charged polymer.

Selon un premier mode de réalisation, le polymère chargé est constitué de polychlorure de vinyle et/ou de nylon avec des inclusions de métal et/ou de noir de carbone.According to a first embodiment, the charged polymer is made of polyvinyl chloride and / or nylon with metal and / or carbon black inclusions.

Selon un second mode de réalisation, le polymère chargé est constitué de polymères tels que le polyacétylène, ionisés.According to a second embodiment, the charged polymer is consisting of polymers such as polyacetylene, ionized.

Les ions utilisés sont constitués par du sodium, de l'iode et/ou du mercure.The ions used consist of sodium, iodine and / or mercury.

Quel que soit le mode de réalisation, la pièce en polymère chargé constitue un carter faisant office de support et de réflecteur pour le tube.Whatever the embodiment, the polymer part loaded is a housing serving as support and reflector for the tube.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit, donnée à titre indicatif et nullement limitatif et réalisée en se référant aux dessins.Other characteristics and advantages of the invention will emerge from the description which follows, given as an indication and in no way limitative and carried out with reference to the drawings.

La figure 1 est un schéma général du dispositif selon l'invention.Figure 1 is a general diagram of the device according to the invention.

Les figures 2, 3, 4 et 5 représentent des modes de réalisation du dispositif selon l'invention en fonction des caractéristiques des différents tubes à allumer.Figures 2, 3, 4 and 5 show modes of realization of the device according to the invention according to the characteristics of the different tubes to be ignited.

La structure de la pièce en polymère chargé 4 peut être de différentes natures.The structure of the charged polymer part 4 can be of different natures.

La fabrication de polychlorure de vinyle ou de nylon chargés par inclusion de poudres, de fibres métalliques ou de noir de carbone, permet la réalisation de résistances chauffantes et de structures légères écoulant les charges électrostatiques. Ces produits sont connus et qualifiés de polymères conducteurs extrinsèques.The manufacture of filled polyvinyl chloride or nylon by inclusion of powders, metallic fibers or black carbon, allows the realization of heating resistors and light structures flowing electrostatic charges. These products are known and qualified as conductive polymers extrinsic.

Sont aussi connus les polymères dopés, intrinsèquement conducteurs du fait de la modification de la molécule par inclusion chimique ou électro-chimique de radicaux ionisés. Il y a aussi été montré qu'en dopant certains polymères tels que le polyacétylène avec des ions (sodium, iodure ou mercure), leur conductivité pouvait atteindre des valeurs proches de celle des métaux.Also known are intrinsically doped polymers conductors due to the modification of the molecule by chemical or electro-chemical inclusion of ionized radicals. There is has also been shown that by doping certain polymers such as polyacetylene with ions (sodium, iodide or mercury), their conductivity could reach values close to that of metals.

Selon l'invention, l'utilisation des caractéristiques de résistivité des polymères chargés 4 permet de substituer ce produit aux ballasts utilisés pour réguler le fonctionnement des tubes fluorescents, tout en évitant l'utilisation du dispositif complexe qu'est le starter.According to the invention, the use of the characteristics of resistivity of charged polymers 4 makes it possible to replace this product to ballasts used to regulate the operation of fluorescent tubes, while avoiding the use of the device complex that is the starter.

De nombreux avantages résultent des caractéristiques physiques du produit qui, par effet de résistance mais également par effet électrostatique, permet l'amorçage du tube fluorescent 1 et par effet Joule en permet le maintien à la température requise pour en optimiser la brillance, ce qui peut avoir un intérêt selon les températures d'utilisation (40°C de point froid).Many advantages result from the characteristics physical properties of the product which, by resistance effect but also by electrostatic effect, allows priming of the fluorescent tube 1 and by Joule effect allows the temperature to be maintained required to optimize gloss, which can have a interest according to the temperatures of use (40 ° C point cold).

Le montage même du dispositif selon l'invention limite les possibilités de perturbation ou parasitage des lignes du réseau électrique aux seuls effets inhérents au fonctionnement de la décharge et des électrodes.The very mounting of the device according to the invention limits the possibility of disturbance or interference of network lines electric only to the effects inherent in the operation of the discharge and electrodes.

La présente invention offre également l'avantage d'un fonctionnement du dispositif quelle que soit la fréquence du réseau où il est connecté. Les produits fabriqués selon le dispositif de l'invention peuvent ainsi être proposés dans des pays où lesdites fréquences sont différentes.The present invention also offers the advantage of a operation of the device regardless of the frequency of network where it is connected. Products manufactured according to the device of the invention can thus be proposed in countries where said frequencies are different.

Il est à noter que plus la fréquence est élevée, moins est sensible l'effet stroboscopique.It should be noted that the higher the frequency, the less sensitive to the strobe effect.

De plus, le dispositif ne comprenant pas de transformateur à fortes fuites magnétiques, le facteur de puissance de l'ensemble constitué par le tube et son circuit d'allumage est très favorable, sauf si une capacité est utilisée.In addition, the device does not include a transformer with strong magnetic leaks, the power factor of the assembly constituted by the tube and its ignition circuit is very favorable, unless a capacity is used.

Au-delà de ces avantages techniques, le dispositif d'allumage de tube fluorescent 1 réalisé selon l'invention permet de sensibles améliorations tant sur les plans de la fabrication que de la commercialisation de sources d'éclairage.Beyond these technical advantages, the ignition device fluorescent tube 1 produced according to the invention allows significant improvements both in terms of manufacturing and the marketing of lighting sources.

Les caractéristiques de poids, d'encombrement, de modularité des montages, d'étanchéité, d'antidéflagration des produits fabriqués selon l'invention sont autant d'avantages offerts aux utilisateurs.The characteristics of weight, size, modularity assemblies, sealing, explosion-proof products manufactured according to the invention are all advantages offered to users.

On voit sur la figure 1 le schéma du circuit électrique d'allumage de tube à décharge gazeuse selon l'invention.We see in Figure 1 the diagram of the electrical circuit ignition gas discharge tube according to the invention.

Il comprend un tube 1 alimenté à partir d'un réseau en courant alternatif et dont les électrodes sont repérées en 2 et 3. L'alimentation en courant alternatif présente l'avantage d'atténuer le noircissement des extrémités des tubes dû à l'effet d'électrolyse et d'en améliorer la durée de vie.It includes a tube 1 supplied from a network in alternating current and whose electrodes are marked in 2 and 3. AC power has the advantage to reduce the blackening of the ends of the tubes due to the effect electrolysis and improve its lifespan.

Il comprend également une pièce 4 réalisée en polymère chargé, de forme telle qu'elle peut être positionnée le long du tube 1 de sorte à constituer un carter servant de support et éventuellement de réflecteur pour le tube.It also includes a part 4 made of polymer loaded, shaped so that it can be positioned along the tube 1 so as to constitute a casing serving as support and possibly a reflector for the tube.

Les extrémités de la pièce 4 sont repérées en 5 et 6 lors de la mise sous tension du circuit, une différence de potentiel entre les extrémités 6 et 5 de la pièce 4 est créée par la résistance de celle-ci.The ends of part 4 are marked at 5 and 6 when powering up the circuit, a potential difference between the ends 6 and 5 of the part 4 is created by the resistance of it.

Fabriquée en polymère chargé, la pièce 4 qui permet l'amorçage instantané du tube, a les caractéristiques d'une résistance, quelle que soit la fréquence du réseau (basse ou haute fréquence).Made of charged polymer, part 4 which allows the instantaneous priming of the tube, has the characteristics of a resistance, whatever the frequency of the network (low or high frequency).

Le niveau de charge du polymère est fonction des caractéristiques de puissance souhaitées et de la montée en température acceptable du dispositif.The charge level of the polymer depends on the desired power characteristics and the rise in acceptable temperature of the device.

Les différentes formes et découpes possibles de la pièce 4 optimisent les caractéristiques thermiques et de puissance du dispositif.The different shapes and possible cuts of the part 4 optimize the thermal and power characteristics of the device.

L'extrémité 5 de la pièce 4 est reliée à l'électrode 3 du tube 1. Le tube 1 est positionné auprès de la pièce 4, ce qui permet la modification de la résistance de la paroi extérieure et modifie la répartition du champ électrique à l'intérieur de la lampe. Ces modifications des lignes de force électriques, dues à la pièce 4 conduisent à l'amorçage du tube 1 qui devient conducteur. Le circuit électrique est fermé lorsque l'électrode 2 du tube 1 est relié au secteur. La position de la pièce 4 auprès du tube 1 favorise la montée en brillance de celui-ci. Cette accélération de la mise en régime constitue un élément tout-à-fait intéressant, en particulier en éclairage domestique. Pour des régimes où la température du point froid du tube deviendrait supérieure à 50°C, l'efficacité globale du système serait légèrement diminuée, il faut cependant noter que la diminution au-delà de 50°C est nettement moins rapide que le gain réalisé au-dessous de la température optimale. L'utilisation d'un amalgame permet par ailleurs de caler le fonctionnement de la lampe sur la température la plus favorable au compromis vitesse de mise en régime/efficacité.The end 5 of the part 4 is connected to the electrode 3 of the tube 1. Tube 1 is positioned near part 4, which allows the modification of the resistance of the external wall and changes the distribution of the electric field inside the lamp. These modifications of the electric power lines, due to the part 4 lead to the priming of the tube 1 which becomes driver. The electrical circuit is closed when the electrode 2 of tube 1 is connected to the sector. The position of room 4 near of the tube 1 promotes the increase in gloss thereof. This acceleration of the setting in regime constitutes an element quite interesting, especially in domestic lighting. For some regimes where the cold point temperature of the tube would become higher than 50 ° C, the overall efficiency of the system would be slightly decreased, it should however be noted that the decrease beyond of 50 ° C is much slower than the gain made below of the optimal temperature. The use of an amalgam also allows to calibrate the operation of the lamp on the temperature most favorable to compromise speed of setting regimen / effectiveness.

Dans un premier mode de réalisation présenté en figure 1, le dispositif est particulièrement destiné à des tubes de dimensions telles que les électrodes sont assez proches. Le faible poids du dispositif et son encombrement réduit en permettant l'utilisation dans divers domaines du luminaire et décoratif, d'intérieur et extérieur.In a first embodiment presented in FIG. 1, the device is particularly intended for tubes of dimensions such that the electrodes are close enough. The low weight of the device and its reduced size allowing the use in various areas of lighting and decorative, interior and outside.

De multiples utilisations possibles du dispositif résultent aussi de possibilités de connexion de plusieurs tubes successifs grâce à un ensemble de formules d'assemblage. Multiple possible uses of the device result also possibilities of connection of several successive tubes thanks to a set of assembly formulas.

Le rôle de l'effet électrostatique demeure quelle que soit la dimension des tubes. Cependant, plus les électrodes des tubes sont éloignées, plus il est nécessaire pour claquer le milieu isolant et pour créer une décharge électrique de disposer d'une tension électrique élevée entre les électrodes, en même temps que d'une réserve de charges électriques.The role of the electrostatic effect remains whatever the size of the tubes. However, the larger the electrodes of the tubes are distant, the more it is necessary to snap the middle insulator and to create an electrical discharge to have a high electrical voltage between the electrodes, together with a reserve of electrical charges.

Pour ce faire, un condensateur 7, monté en série avec la pièce 4 et une diode 9, est chargé en continu au travers d'une résistance 8. Présenté en figure 2, ce dispositif étant sous tension, lorsque le gaz du tube 1 est ionisé, le tube étant alors conducteur, le condensateur 7 se décharge entre les électrodes 3 et 2 du tube 1 en provoquant l'amorçage.To do this, a capacitor 7, mounted in series with the part 4 and a diode 9, is continuously charged through a resistance 8. Presented in FIG. 2, this device being under voltage, when the gas in tube 1 is ionized, the tube then being conductor, the capacitor 7 discharges between the electrodes 3 and 2 of tube 1 by causing priming.

La pièce 4 et le condensateur 7 maintiennent alors la brillance du tube, la résistance 8 et la diode 9 se trouvant pratiquement hors circuit du fait de la haute impédance de la résistance 8.The part 4 and the capacitor 7 then maintain the shine of the tube, resistor 8 and diode 9 being practically switched off due to the high impedance of the resistance 8.

Avantageusement, ce même circuit composé du condensateur 7 de la résistance 8 et de la diode 9 peut être monté sur chaque électrode 2 et 3 du tube 1 au travers des pièces 10 et 11 constituant un dédoublement de la pièce 4. Ce montage présenté en figure 3 permet un doublement de tension favorisant l'amorçage du tube.Advantageously, this same circuit composed of the capacitor 7 resistor 8 and diode 9 can be mounted on each electrode 2 and 3 of tube 1 through parts 10 and 11 constituting a duplication of part 4. This assembly presented in Figure 3 allows a doubling of voltage favoring the priming of the tube.

De la même façon, pour les tubes présentant les dimensions les plus grandes, peuvent être employés des montages multiplicateurs de puissance de la décharge, la pièce 4 conservant ses caractéristiques et son rôle, fonction du rapport entre les proportions de charge du polymère et les caractéristiques de longueur, de volume et de puissance du dispositif.Similarly, for tubes with the dimensions larger, can be used fixtures discharge power multipliers, piece 4 retaining its characteristics and role, a function of the relationship between charge proportions of the polymer and the characteristics of length, volume and power of the device.

Ces montages connus sont réalisés au moyen de ponts de diodes et sont schématisés en figure 4.These known assemblies are produced by means of diode bridges and are shown diagrammatically in Figure 4.

On peut également prévoir d'inclure, dans le circuit, selon le schéma présenté en figure 5, les condensateurs 12 et 13 pilotés par les commutateurs 14 et 15, de sorte à modifier la brillance du tube.We can also plan to include, in the circuit, according to the diagram presented in figure 5, the capacitors 12 and 13 controlled by switches 14 and 15, so as to modify the brightness of the tube.

De la même façon, il y a lieu de noter que le dispositif, selon l'invention, représenté à la figure 1, où il n'y a ni condensateur, ni résistance, ni diode, permet d'utiliser avec les tubes à décharge gazeuse des variateurs d'intensité, pilotés manuellement ou au moyen d'une horloge et éventuellement par diverses sortes de capteurs, lumineux ou sonores. Peut ainsi être obtenue, la variabilité d'intensité lumineuse de la source d'éclairage.Likewise, it should be noted that the device, according to the invention, shown in Figure 1, where there is neither capacitor, neither resistor, nor diode, allows to use with gas discharge tubes of the dimmers, controlled manually or by means of a clock and possibly by various kinds of sensors, light or sound. Can be obtained, the variability of light intensity of the source lighting.

Selon les figures 4 et 5, les circuits électriques peuvent de structures plus complexes en proposant une pluralité de diodes D1, D2, D3 et D4 et de condensateurs C1 et C2. According to Figures 4 and 5, the electrical circuits can more complex structures by offering a plurality of diodes D1, D2, D3 and D4 and capacitors C1 and C2.
