Description
L’objet de la présente invention concerne un dispositif d’éclairage cylindrique, encore appelé projecteur cylindrique, comprenant des diodes électroluminescentes (LED) et un conduit interne permettant le refroidissement dudit dispositif d’éclairage. L’objet de la présente invention concerne également l’utilisation dudit dispositif d’éclairage pour éclairer un milieu extérieur ou pour éclairer un site industriel, agricole ou maritime, tel que le pont d’un navire.The object of the present invention relates to a cylindrical lighting device, also called a cylindrical projector, comprising light-emitting diodes (LEDs) and an internal duct allowing the cooling of said lighting device. The object of the present invention also relates to the use of said lighting device for illuminating an outdoor environment or for illuminating an industrial, agricultural or maritime site, such as the deck of a ship.
Le succès rencontré par les dispositifs d'éclairage à LED s’explique par leurs nombreux avantages techniques, telle que leur faible consommation d'énergie, leur longue durée de vie, leur compacité et faible poids, leur niveau de sécurité élevé, leur résistance aux contraintes mécaniques (telles que les vibrations), les longueurs d’onde spécifiques de leurs lumières, etc.The success encountered by LED lighting devices is explained by their many technical advantages, such as their low energy consumption, their long life, their compactness and low weight, their high level of safety, their resistance to mechanical stresses (such as vibration), specific wavelengths of their lights, etc.
Les développements techniques des LED ont amené à une recherche de l’augmentation de leur puissance, c’est-à-dire de l’augmentation de l’éclairage fourni.The technical developments of LEDs have led to a search for increasing their power, i.e. increasing the lighting provided.
Or, le principal problème rencontré dans le développement industriel des dispositifs d'éclairage à LED est l'élimination de la chaleur générée par celles-ci.However, the main problem encountered in the industrial development of LED lighting devices is the elimination of the heat generated by them.
Toute source de lumière génère de la chaleur (même minimum). Or, lors de l'utilisation de LED en particulier à hautes puissances, il existe un risque de surchauffe des LED pendant leur fonctionnement, ce qui entraîne une diminution du rendement lumineux, de la durée de vie et de la fiabilité de ces LED.Any light source generates heat (even minimal). However, when using LEDs, in particular at high powers, there is a risk of overheating of the LEDs during their operation, which leads to a reduction in the luminous efficiency, the lifetime and the reliability of these LEDs.
Plusieurs solutions ont été décrites dans l’art pour chercher à maintenir une température optimale de fonctionnement des LED, en particulier de LED de hautes puissances, en particulier par dissipation thermique. Par exemple, dans RU2684461 il est décrit une lampe LED avec un boîtier creux et des extrémités ouvertes, sur la surface extérieure duquel un module de diode électroluminescente est connecté à une unité d'alimentation.Several solutions have been described in the art to seek to maintain an optimum operating temperature of LEDs, in particular high-power LEDs, in particular by heat dissipation. For example, in RU2684461 there is described an LED lamp with a hollow housing and open ends, on the outer surface of which a light-emitting diode module is connected to a power supply unit.
Dans US201512443 est décrit une ampoule comprenant au moins un corps de refroidissement cylindrique ayant au moins une surface de support externe, où il est disposé au moins une source LED, un boîtier de commande installé dans un espace creux du corps de refroidissement cylindrique.In US201512443 is described a bulb comprising at least one cylindrical cooling body having at least one external support surface, where there is arranged at least one LED source, a control box installed in a hollow space of the cylindrical cooling body.
RU2012147002 divulgue une lampe LED haute puissance contenant un émetteur à base de modules ou de bandes LED, des dissipateurs de refroidissement LED.RU2012147002 discloses a high power LED lamp containing an emitter based on LED modules or strips, LED cooling sinks.
DE10201215652A1 divulgue une lampe LED cylindrique à un élément de refroidissement disposé à l'intérieur d'un support de lumière LED en verre dans laquelle les LED sont disposées les unes à la suite des autres sur une surface plane pourvue d’un radiateur.DE10201215652A1 discloses a cylindrical LED lamp with a cooling element arranged inside a glass LED light support in which the LEDs are arranged one after the other on a flat surface provided with a radiator.
Toutefois, ces solutions ne permettent pas un refroidissement optimum des LED, surtout lorsqu’un grand angle d’éclairage, nécessitant plusieurs LED de hautes puissances sont disposées dans le moyen d’éclairage.However, these solutions do not allow optimum cooling of the LEDs, especially when a wide lighting angle, requiring several high-power LEDs are arranged in the lighting means.
Or, de tels dispositifs d’éclairages, si elles peuvent être utiles pour tout à chacun, ils sont particulièrement recherchés pour le milieu extérieur, ou encore dans les domaines industriels, agricoles ou maritime qui nécessitent des lampes puissantes avec des angles d’éclairage grands. En particulier, de telles lampes sont d’un très grand intérêt dans le domaine maritime, tel que le pont d’un bateau, où des points d’éclairages important sont nécessaires, dans des conditions pouvant être difficile pour la propagation de la lumière (brume, embruns, etc.).However, such lighting devices, if they can be useful for everyone, they are particularly sought after for the outdoor environment, or even in the industrial, agricultural or maritime fields which require powerful lamps with large lighting angles. . In particular, such lamps are of great interest in the maritime field, such as the deck of a boat, where important lighting points are necessary, in conditions that can be difficult for the propagation of light ( mist, spray, etc.).
En effet, si l’état de la technique actuel en matière de LED propose quelques LED à usage maritime, les solutions proposées sont typiquement des projecteurs avec des orientations lumineuses très spécifiques, du même type que ceux trouvés pour l’usage domestique (par exemple les projecteurs d’entrées de garage), mal adapté pour le pont d’un bateau.Indeed, if the current state of the art in terms of LEDs offers some LEDs for maritime use, the solutions offered are typically projectors with very specific light orientations, of the same type as those found for domestic use (for example driveway floodlights), ill-suited for the deck of a boat.
La présente invention cherche à résoudre ces problèmes, notamment à fournir des lampes LED puissantes présentant en particulier des angles d’éclairage importants.The present invention seeks to solve these problems, in particular to provide powerful LED lamps having in particular large lighting angles.

DEFINITIONSDEFINITIONS
Par « dispositif d’éclairage cylindrique », il est compris dans le cadre de la présente invention une lampe, c’est-à-dire un support pour un ou des points d’éclairage (c’est-à-dire des LED dans le cadre de la présente invention). La lampe selon la présente invention est majoritairement constituée d’un cylindre, d’où l’expression « dispositif d’éclairage cylindrique ». Dans le cadre de la présente invention un cylindre est une surface réglée dont les génératrices sont parallèles, c’est-à-dire une surface dans l’espace constituée de droites parallèles. Ces axes parallèles définissent « l’axe longitudinal X » qui est l’axe passant par le centre de gravité de la surface réglée du cylindre et parallèle aux génératrices. Le dispositif d’éclairage cylindrique selon l’invention peut comprendre des irrégularités de surface, prenant par exemple la forme de têtes de vis, de valve. En tant que tel, le dispositif d’éclairage ne comprend pas le moyen, appelé moyen de fixation externe du dispositif d’éclairage cylindrique permettant de le fixer à un support. De manière préférée, il est compris dans le cadre de la présente invention qu’un cylindre est un tube, c’est-à-dire un cylindre ayant une section transversale de forme circulaire ou ovale.By "cylindrical lighting device", it is understood within the scope of the present invention a lamp, that is to say a support for one or more lighting points (that is to say LEDs in the scope of the present invention). The lamp according to the present invention mainly consists of a cylinder, hence the expression “cylindrical lighting device”. In the context of the present invention, a cylinder is a ruled surface whose generatrices are parallel, that is to say a surface in space made up of parallel straight lines. These parallel axes define the "longitudinal axis X" which is the axis passing through the center of gravity of the ruled surface of the cylinder and parallel to the generatrices. The cylindrical lighting device according to the invention may comprise surface irregularities, for example taking the form of screw heads, valves. As such, the lighting device does not include the means, called the external fixing means of the cylindrical lighting device, for fixing it to a support. Preferably, it is understood within the scope of the present invention that a cylinder is a tube, that is to say a cylinder having a cross-section of circular or oval shape.
Par « diodes électroluminescentes », plus connue sous l’appellation LED (de l’anglais « light-emitting diode ») désigne un composant optoélectronique qui permet l’émission de lumière monochromatique.By “light-emitting diodes”, better known under the name LED (from the English “light-emitting diode”) designates an optoelectronic component which allows the emission of monochromatic light.
Par « conduit interne traversant de section transversale régulière », il est compris dans le cadre de la présente invention un conduit traversant de part en part le dispositif d’éclairage cylindrique, préférentiellement dans l’allongement de l’axe longitudinal X. La section transversale du conduit ainsi définit est homogène sur sa longueur, c’est-à-dire que le conduit prend généralement la forme d’un cylindre.By "internal through conduit of regular cross section", it is understood within the scope of the present invention a through conduit right through the cylindrical lighting device, preferably in the elongation of the longitudinal axis X. The cross section of the duct thus defined is homogeneous over its length, that is to say that the duct generally takes the form of a cylinder.
Par « site industriel, agricole ou maritime », il est compris dans le cadre de la présente invention une zone géographie d’activité dédiée à une industrie, à une activité agricole ou une activité maritime.By "industrial, agricultural or maritime site", it is understood in the context of the present invention a geographical area of activity dedicated to an industry, an agricultural activity or a maritime activity.
