Description

GENERATEUR DE LUMIERE POUR LE BLANCHIMENT DES DENTS  LIGHT GENERATOR FOR TOOTH WHITENING
L'invention concerne de manière générale le blanchiment des dents. Plus particulièrement l'invention concerne un générateur de lumière à diodes électroluminescentes pour le blanchiment des dents. The invention relates generally to tooth whitening. More particularly, the invention relates to a light emitting diode light generator for whitening teeth.
Les causes les plus fréquentes de la décoloration des dents chez les personnes sont le vieillissement et la consommation de substances de coloration. Avec le vieillissement, la structure minérale des dents change et peut causer une diminution de la brillance de l'émail. Les dents peuvent également devenir colorées du fait de pigments bactériens, de produits alimentaires consommés, du tabac et de certains médicaments.  The most common causes of tooth discoloration in people are aging and the consumption of coloring substances. With aging, the mineral structure of the teeth changes and can cause a decrease in enamel brightness. Teeth can also become colored because of bacterial pigments, consumed food products, tobacco and certain medications.
Le blanchiment des dents a gagné en popularité ces dernières années et différentes solutions sont proposées, soit directement aux consommateurs dans le commerce, soit par les dentistes à leurs patients.  Tooth whitening has gained popularity in recent years and different solutions are offered, either directly to consumers in the trade, or by dentists to their patients.
En vente directe aux consommateurs, il est connu une solution comprenant un agent de blanchiment, sous la forme d'un gel ou d'une pate dentaire, et un générateur de lumière. Le gel dentaire est appliqué sur la surface des dents et le générateur de lumière est utilisé pour l'activation et la polymérisation de l'agent de blanchiment. Différentes compositions d'agent de blanchiment sont connues, les plus efficaces contenant du peroxyde d'hydrogène. Les générateurs de lumière associés sont des dispositifs portables et légers que l'utilisateur peut tenir dans sa main et placer dans sa boucle pour l'éclairage de l'agent de blanchiment. Ces générateurs de lumière utilisent des diodes électroluminescents LED (« Light Emitting Diode » en anglais) qui émettent une lumière bleue froide, riche en en ultra-violet.  In direct sale to consumers, there is known a solution comprising a bleaching agent, in the form of a gel or a dental paste, and a light generator. The dental gel is applied to the tooth surface and the light generator is used for the activation and polymerization of the bleaching agent. Various bleaching compositions are known, the most effective containing hydrogen peroxide. The associated light generators are portable and lightweight devices that the user can hold in his hand and place in his loop for the illumination of the bleaching agent. These light generators use LEDs ("Light Emitting Diode") that emit a cold blue light, rich in ultra-violet.
Les générateurs de lumière connus pâtissent d'un certain nombre d'inconvénients et d'insuffisances.  Known light generators suffer from a number of disadvantages and shortcomings.
La lumière bleue émise manque généralement d'uniformité et l'agent de blanchiment à la surface des dents n'est pas éclairé de manière homogène. Il peut en découler des défauts de blancheur qui persistent sur les dents après le traitement.  The blue light emitted is generally lacking in uniformity and the whitening agent on the surface of the teeth is not uniformly illuminated. This may result in whiteness defects that persist on the teeth after treatment.
Le temps d'exposition à la lumière et la puissance lumineuse sont rarement réglables et restent insuffisamment contrôlés dans les générateurs connus, qui sont la plupart du temps conçus et vendus pour des compositions de blanchiment spécifiques. Lorsqu'une possibilité de réglage ou un contrôle d'exposition existe, cette possibilité reste cependant très limitée et peu précise. Les utilisateurs peuvent donc encourir des risques de surexposition à la lumière, notamment lorsque le gel dentaire de blanchiment utilisé n'est pas adapté au générateur ou inversement. Une surexposition lumineuse peut entraîner un sur-échauffement de la pulpe dentaire et des tissus des gencives, ce qui peut avoir des conséquences sur la santé dentaire et buccale. The light exposure time and light power are rarely adjustable and remain insufficiently controlled in known generators, which are mostly designed and sold for specific bleaching compositions. When an adjustment possibility or an exposure control exists, this possibility remains very limited and not very precise. Users may therefore incur risks of overexposure to light, especially when the bleaching dental gel used is not adapted to the generator or vice versa. A Light overexposure can lead to overheating of the dental pulp and gum tissue, which can affect dental and oral health.
La présente invention a pour objectif d'apporter des solutions aux inconvénients exposés ci-dessus de la technique antérieure en proposant un générateur de lumière de nouvelle génération, bien adapté pour une utilisation directe les consommateurs et aussi par les professionnels.  The present invention aims to provide solutions to the disadvantages described above of the prior art by providing a new generation of light generator, well suited for direct use by consumers and also by professionals.
Selon un premier aspect, la présente invention concerne un générateur de lumière de blanchiment des dents en association avec un gel dentaire de blanchiment comprenant une pluralité de diodes électroluminescentes d'émission de lumière et des moyens de commande. Conformément à l'invention, les diodes électroluminescentes d'émission de lumière sont des composants miniatures de forme carrée ou rectangulaire, aptes à émettre une lumière de forte intensité avec une faible consommation de courant et du type dit CMS pour « composant monté en surface ».  According to a first aspect, the present invention relates to a tooth whitening light generator in combination with a dental whitening gel comprising a plurality of light-emitting light emitting diodes and control means. According to the invention, the light-emitting light-emitting diodes are miniature components of square or rectangular shape, able to emit a high-intensity light with a low current consumption and of the so-called SMD type for "surface-mounted component" .
Selon une autre forme de réalisation, les diodes électroluminescentes d'émission de lumière sont des composants sub-miniatures.  According to another embodiment, the light-emitting light emitting diodes are sub-miniature components.
Selon une caractéristique particulière de l'invention, les diodes électroluminescentes d'émission de lumière sont montées électriquement en parallèle et alimentées par un circuit d'attaque de diodes de type générateur de courant.  According to a particular characteristic of the invention, the light-emitting light emitting diodes are electrically connected in parallel and fed by a diode driver of the current generator type.
Selon une autre caractéristique particulière de l'invention, les moyens de commande comprennent un microcontrôleur programmable autorisant un fonctionnement du générateur selon une pluralité de modes de fonctionnement.  According to another particular characteristic of the invention, the control means comprise a programmable microcontroller allowing operation of the generator according to a plurality of modes of operation.
Selon encore une autre caractéristique particulière de l'invention, le générateur comprend également un écran et une pluralité de touches connectés au microcontrôleur programmable pour la commande du générateur dans ladite pluralité de modes de fonctionnement à travers des menus s'affichant sur l'écran et des actions d'appui sur lesdites touches.  According to yet another particular characteristic of the invention, the generator also comprises a screen and a plurality of keys connected to the programmable microcontroller for controlling the generator in said plurality of operating modes through menus displayed on the screen and pressing actions on said keys.
Le document de brevet US2013/0454457 divulgue un générateur de lumière du genre mentionné dans le préambule, mais il n'est adapté qu'à une seule sorte de gel.  US2013 / 0454457 discloses a light generator of the kind mentioned in the preamble, but it is suitable for only one kind of gel.
Selon encore une autre caractéristique particulière de l'invention, les diodes électroluminescentes d'émission de lumière sont de type monochromatique ou plurichromatique.  According to yet another particular characteristic of the invention, the electroluminescent light-emitting diodes are of the monochromatic or plurichromatic type.
On a donc l'avantage que ledit générateur s'adapte à toute sorte de gel. D'autres avantages et caractéristiques de la présente invention apparaîtront plus clairement à la lecture de la description ci-dessous de plusieurs formes de réalisation particulières en référence aux dessins annexés, dans lesquels : There is therefore the advantage that said generator adapts to any kind of gel. Other advantages and features of the present invention will appear more clearly on reading the following description of several particular embodiments with reference to the accompanying drawings, in which:
- la Fig.1 est une vue de dessus d'un générateur de lumière selon l'invention ; - la Fig.2 est le schéma électrique du générateur de lumière de la Fig.1 ;  - Fig.1 is a top view of a light generator according to the invention; - Fig.2 is the electrical diagram of the light generator of Fig.1;
L'architecture matérielle et le fonctionnement d'une forme de réalisation particulière 1 du générateur de lumière selon l'invention sont maintenant décrits en référence aux Figs.1 et 2.  The hardware architecture and the operation of a particular embodiment 1 of the light generator according to the invention are now described with reference to FIGS. 1 and 2.
Ce générateur 1 se présente sous la forme d'un boîtier prévu pour tenir dans la main et ayant une partie avant 10 de forme sensiblement semi-circulaire pour correspondre à la courbure d'une mâchoire humaine sur laquelle il doit s'appliquer.  This generator 1 is in the form of a housing adapted to hold in the hand and having a front portion 10 of substantially semicircular shape to correspond to the curvature of a human jaw on which it must apply.
La vue extérieure de dessus du générateur 1 à la Fig.1 montre les différents moyens d'interface homme-machine équipant le générateur. Ces moyens d'interface comprennent , notamment un écran 11 , des touches de commande 12, 14, 15 et un bruiteur 17 situé à l'intérieur du boîtier et débouchant à l'extérieur.  The external top view of the generator 1 in Fig.1 shows the different means of human-machine interface equipping the generator. These interface means comprise, in particular a screen 11, control keys 12, 14, 15 and a buzzer 17 located inside the housing and opening to the outside.
La touche 15 est une touche de marche/arrêt (ON/OFF). Les touches 12 et 14 sont utilisés pour régler l'affichage de l'heure et différents minutages, pour définir le temps d'apparition du son par le bruiteur 17 et pour commnder la puissance de la lumière émise par le générateur 1.  Key 15 is an ON / OFF key. The keys 12 and 14 are used to set the time display and various timings, to define the time of appearance of the sound by the buzzer 17 and to commnder the power of the light emitted by the generator 1.
Dans la partie intérieure de son boîtier, le générateur 1 comporte essentiellement une gouttière 100 et un circuit de réseau de diodes 101 qui suivent la forme semi-circulaire de la partie avant 10 du générateur. Il est prévu aussi un circuit imprimé destiné à réunir les différents éléments d'un circuit de commande explicité ci- dessous à l'aide de la figure 2.  In the inner part of its housing, the generator 1 essentially comprises a trough 100 and a diode array circuit 101 which follow the semicircular shape of the front part 10 of the generator. There is also provided a printed circuit intended to bring together the different elements of a control circuit explained below with the aid of FIG.
Le circuit de commande comporte un microcontrôleur programmable 202, une batterie rechargeable 203, le buzzer 17, les touches 12,14,15 dont les parties visibles à l'extérieur du boîtier sont montrées à la Fig.1.  The control circuit comprises a programmable microcontroller 202, a rechargeable battery 203, the buzzer 17, the keys 12, 14, 15 whose visible parts outside the housing are shown in FIG.
Dans cette forme de réalisation de l'invention, la gouttière 100 est destinée à permettre le montage d'un embout buccal (non représenté) sur le générateur 1. Cet embout buccal est placé par l'utilisateur entre ses lèvres et ses gencives. Il participe au maintien en position du générateur 1 en regard des dents à traiter et au recueil des substances salivaires. Il est amovible de manière à pouvoir être nettoyé et remplacé si besoin.  In this embodiment of the invention, the trough 100 is intended to allow the mounting of a mouthpiece (not shown) on the generator 1. This mouthpiece is placed by the user between his lips and his gums. It participates in maintaining the position of the generator 1 facing the teeth to be treated and the collection of salivary substances. It is removable so that it can be cleaned and replaced if necessary.
Le circuit de réseau de diodes 101 est formé d'une pluralité de diodes électroluminescentes L1 , L2, ...L10 qui sont montées électriquement en parallèle et comporte leurs cathodes reliées ensemble à une masse du circuit et leurs anodes qui sont aussi reliées ensemble et alimentées en courant par un circuit LD qui est un circuit d'attaque de diodes, dit « LED Driver » en anglais, ayant une configuration de générateur de courant. La fonction de générateur de courant du circuit LD est ici obtenue de manière classique au moyen d'une transistor T1 de type PNP et de deux résistances R1 et R2. Une électrode de base du transistor T1 est reliée à une sortie de commande du microcontrôleur 202 qui commande le courant injecté dans les diodes Led. Le microcontrôleur 202 a ainsi la possibilité de commander et régler l'intensité lumineuse qui est émise par le générateur 1. The diode array circuit 101 is formed of a plurality of light-emitting diodes L1, L2, ... L10 which are electrically connected in parallel and have their cathodes connected together to a ground of the circuit and their anodes which are also connected together and powered by an LD circuit which is a diode driver, said "LED Driver" in English, having a current generator configuration. The current generator function of the circuit LD is here obtained conventionally by means of a PNP transistor T1 and two resistors R1 and R2. A base electrode of the transistor T1 is connected to a control output of the microcontroller 202 which controls the current injected into the Led diodes. The microcontroller 202 thus has the ability to control and adjust the light intensity that is emitted by the generator 1.
Conformément à l'invention, les diodes Led sont des composants de type CMS (Composant Monté en Surface), de forme carrée ou rectangulaire. Les diodes Led utilisées dans l'invention sont des composants miniatures ou sub-miniatures, aptes à émettre une lumière de forte intensité avec une faible consommation de courant.  According to the invention, the LEDs are components of the type CMS (Surface Mounted Component), of square or rectangular shape. The LEDs used in the invention are miniature or sub-miniature components, able to emit high intensity light with low current consumption.
Les diodes électroluminescentes Led utilisées ici sont par exemple du type de celles commercialisées par la société Philips dans sa gamme Lumineds (« Philips » et « Lumineds » sont des marques déposées).  The LED light emitting diodes used here are for example of the type sold by Philips in its Lumineds range ("Philips" and "Lumineds" are registered trademarks).
Les diodes Led sont généralement choisies pour avoir une longueur d'onde d'émission de lumière qui soit celle qui réagit le mieux avec le gel dentaire de blanchiment utilisé. Une lumière bleue froide ou une longueur d'onde dans la plage de 480 nm à 510 nm sont souvent adaptées.  Led diodes are generally chosen to have a light emission wavelength that is the one that reacts best with the dental whitening gel used. Cold blue light or a wavelength in the range of 480 nm to 510 nm is often suitable.
Conformément à l'invention, selon l'application de générateur envisagée, il pourra être fait appel à des diodes Led monochromatiques ou à des diodes bichromatiques ou trichromatiques, les diodes plurichromatiques autorisant une adaptation de la couleur de la lumière émise pour différents gels dentaires de blanchiment utilisés avec un même générateur.  According to the invention, depending on the application of the generator envisaged, it will be possible to use monochromatic LED diodes or bichromatic or trichromatic diodes, the plurichromatic diodes allowing an adaptation of the color of the light emitted for different dental gels. bleaching used with the same generator.
L'invention permet la réalisation de rangées de diodes Led très serrées et denses, comprenant un plus grand nombre de diodes par rangée, sans accroissement de la consommation électrique du générateur, voire avec une réduction de celle-ci, par rapport aux générateurs de la technique antérieure. Ce plus grand nombre de diodes, favorisé par la forme carrée ou rectangulaire des diodes et la technologie CMS, permet d'améliorer sensiblement l'uniformité du faisceau lumineux émis par le générateur selon l'invention, par rapport aux générateurs de la technique antérieure.  The invention allows the realization of rows of very dense and dense LED diodes, comprising a larger number of diodes per row, without increasing the power consumption of the generator, or even with a reduction thereof, compared to the generators of the prior art. This larger number of diodes, favored by the square or rectangular shape of the diodes and the CMS technology, significantly improves the uniformity of the light beam emitted by the generator according to the invention, compared to generators of the prior art.
Outre le circuit de réseau de diodes 101 , le circuit imprimé supporte également tous les autres composants électroniques et électriques du générateur 1 et assure les connexions électriques nécessaires à la réalisation du circuit électronique du générateur 1. Dans cette forme de réalisation, le microcontrôleur 202 est aussi un composant de type CMS qui est reporté sur le circuit imprimé. Le microcontrôleur 202 est géré par un microprogramme contenu dans une mémoire 300 afin de commander le fonctionnement de l'ensemble du générateur 1. On notera ici que ce microprogramme pourra avantageusement être téléchargé dans le microcontrôleur 202 à travers une prise micro-USB (non montrée sur les figures) lors de la programmation de l'appareil en fin de fabrication de celui-ci. In addition to the diode array circuit 101, the printed circuit also supports all the other electronic and electrical components of the generator 1 and provides the electrical connections necessary for producing the electronic circuit of the generator 1. In this embodiment, the microcontroller 202 is also a CMS-type component that is carried on the printed circuit. The microcontroller 202 is managed by a firmware contained in a memory 300 in order to control the operation of the generator set 1. It will be noted here that this microprogram can advantageously be downloaded into the microcontroller 202 through a micro-USB jack (not shown in the figures) when programming the device at the end of its production.
La batterie rechargeable 203 est typiquement de type Lithium-Ion et est rechargeable à travers une prise micro-USB, par exemple, sous la commande du microcontrôleur 202.  The rechargeable battery 203 is typically of the Lithium-Ion type and is rechargeable through a micro-USB socket, for example, under the control of the microcontroller 202.
