Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un réflecteur notamment pour appareil d'éclairage comprenant des moyens de fixation et au moins un demi-miroir.The present invention relates to a reflector, in particular for a lighting device. comprising fixing means and at least half a mirror.

Elle trouve notamment son application dans l'éclairage localisé de gondoles dans les commerces de discount, les supermarchés ou encore les halls d'exposition.It finds its application in particular in the localized lighting of gondolas in the discount stores, supermarkets or even exhibition halls.

Etat de la technique antérieureState of the prior art

Le brevet américain 6,244,729 décrit un appareil d'éclairage comprenant un tube fluorescent de type allongé et un réflecteur également de type allongé. La forme du réflecteur est variable. Pour cela un système d'ajustement est disposé au moins à une extrémité du réflecteur. Ce système d'ajustement permet de modifier la forme du réflecteur, de manière à garder un rayon de courbure uniforme, et par conséquent d'obtenir différentes distributions lumineuses selon les réglages effectués.American patent 6,244,729 describes a lighting device comprising a tube elongated type fluorescent and also an elongated type reflector. The shape of the reflector is variable. For this, an adjustment system is arranged at least one end of the reflector. This adjustment system makes it possible to modify the shape of the reflector, so as to keep a uniform radius of curvature, and therefore to obtain different light distributions according to the settings made.

Cependant, un tel réflecteur possède une structure complexe car il nécessite, d'une part, d'être constitué par un matériau flexible, et il comprend, d'autre part, un système d'ajustement composé de diverses pièces, donc particulièrement compliqué, permettant d'orienter la distribution lumineuse.However, such a reflector has a complex structure because it requires, of a on the one hand, to be made of a flexible material, and on the other hand it includes a system adjustment made up of various parts, therefore particularly complicated, allowing to guide the light distribution.

De plus l'obtention d'une distribution lumineuse prédéterminée, correspondant par exemple à un besoin spécifique d'un client, nécessite un réglage fin qui n'est pas forcément à la portée du client.In addition, obtaining a predetermined light distribution, corresponding by example to a specific customer need, requires fine tuning which is not necessarily within reach of the client.

Exposé de l'inventionStatement of the invention

La présente invention a pour but de proposer un réflecteur de structure plus simple qui réponde au souhait du client.The object of the present invention is to propose a simpler structure reflector which meets the customer's wishes.

En effet, les clients, notamment ceux des petits et grands commerces, souhaitent obtenir un éclairage localisé de leurs gondoles en tenant compte des contraintes spécifiques liées à cette application. Pour cela, ils souhaitent notamment disposer de deux types de distributions lumineuses bidirectionnelles, à savoir :

  • une première distribution lumineuse de type double asymétrique 20/25°,
  • une deuxième distribution lumineuse de type double asymétrique 35/40°.
Indeed, customers, especially those of small and large businesses, want to obtain localized lighting of their gondolas taking into account the specific constraints related to this application. For this, they particularly want to have two types of bidirectional light distributions, namely:
  • a first light distribution of the asymmetrical double type 20/25 °,
  • a second asymmetrical 35/40 ° double light distribution.

A cet effet, le réflecteur selon l'invention est remarquable en ce qu'il comprend des moyens de fixation et au moins un demi-miroir de forme telle qu'il est apte à se positionner dans les moyens de fixation et à délivrer une première distribution lumineuse pour une première position de montage du au moins un demi-miroir dans les moyens de fixation et à délivrer une deuxième distribution lumineuse pour une deuxième position de montage du au moins un demi-miroir dans les moyens de fixation correspondant à un retournement dudit demi-miroir.To this end, the reflector according to the invention is remarkable in that it comprises fixing means and at least one half-mirror so shaped as to be able to position itself in the fixing means and in delivering a first light distribution for a first mounting position of the at least half-mirror in the fixing means and at deliver a second light distribution for a second mounting position from to at least half a mirror in the fixing means corresponding to a reversal of said half-mirror.

La présente invention permet donc d'obtenir la première distribution lumineuse souhaitée pour une première position de montage du demi-miroir dans les moyens de fixation. Le client peut également obtenir, de façon simple, la deuxième distribution lumineuse souhaitée en démontant le demi-miroir, en le retournant et en lui faisant prendre une deuxième position de montage dans les moyens de fixation. Ainsi, il est possible avec un seul réflecteur de disposer d'au moins deux distributions lumineuses différentes, ce qui évite au client d'acheter deux réflecteurs, un réflecteur dédié à chaque distribution lumineuse, pour obtenir le même résultat.The present invention therefore makes it possible to obtain the first light distribution desired for a first mounting position of the half-mirror in the means of fixation. The customer can also easily obtain the second distribution desired light by dismantling the half-mirror, turning it over and making it set a second mounting position in the fixing means. So it is possible with a single reflector to have at least two different light distributions, which saves the customer from buying two reflectors, one dedicated to each distribution bright, to get the same result.

La présente invention concerne également un luminaire comprenant un tel réflecteur et au moins une lampe. Dans le cas, par exemple, où ledit luminaire est apte à être équipé d'une ou deux lampes, on dispose alors d'un luminaire permettant de fournir quatre configurations différentes selon la distribution lumineuse et le nombre de lampes souhaités au lieu d'avoir quatre luminaires différents dédiés chacun à une configuration donnée. Ainsi, le client peut commander un seul produit qu'il positionne à sa guise en fonction de l'application recherchée et qu'il peut éventuellement modifier ultérieurement en fonction d'une nouvelle répartition d'éclairage qu'il souhaite obtenir parmi un ensemble de répartitions d'éclairage possibles. Cette solution est donc particulièrement simple et économique.The present invention also relates to a luminaire comprising such a reflector and at least one lamp. In the case, for example, where said luminaire is suitable for be equipped with one or two lamps, we then have a luminaire to provide four different configurations depending on the light distribution and the number of lamps instead of having four different luminaires each dedicated to a configuration given. Thus, the customer can order a single product which he positions as he pleases. depending on the desired application and which it can possibly modify later by function of a new lighting distribution that he wishes to obtain from a set of possible light distributions. This solution is therefore particularly simple and economic.

Exposé détaillé d'au moins un mode de réalisation de l'inventionDetailed description of at least one embodiment of the invention

La présente invention concerne un réflecteur comportant des miroirs, lesdits miroirs étant insérés dans le réflecteur. Ces réflecteurs sont notamment destinés à des systèmes de rail d'éclairage. Les miroirs sont utilisés pour orienter le flux lumineux. Dans le mode de réalisation qui suit, ils sont en aluminium et possèdent une forme adaptée à deux distributions spécifiques souhaitées lors de l'éclairage localisé des gondoles de supermarchés et des commerces équivalents. Les miroirs peuvent cependant avoir des profils et des matériaux différents, avec des aspects de surface différents tels que mat, brillant ou semi-brillant, afin de répartir la lumière suivant une application donnée qui peut être, par exemple, une distribution lumineuse intensive, extensive, asymétriques ou encore bidirectionnelles.The present invention relates to a reflector comprising mirrors, said mirrors being inserted into the reflector. These reflectors are in particular intended for lighting rail. Mirrors are used to orient the luminous flux. In the mode of realization which follows, they are out of aluminum and have a form adapted to two Specific distributions desired when localized lighting of supermarket gondolas and equivalent businesses. Mirrors can however have profiles and different materials, with different surface aspects such as matt, glossy or semi-glossy, in order to distribute the light according to a given application which can be, for example example, an intensive, extensive, asymmetrical or even light distribution bidirectional.

Les Figs. 1a et 1b représentent un luminaire équipé d'une lampe et d'un demi-miroir ainsi que la distribution lumineuse correspondant à deux positions différentes du demi-miroir. Le luminaire (1) comprend un réflecteur (10) de structure symétrique par rapport à un axe (2) et une lampe (20) de type néon, par exemple, placée de préférence sur l'axe de symétrie (2) à une hauteur dépendant du niveau d'éclairement vertical souhaité.Figs. 1a and 1b represent a luminaire equipped with a lamp and a half-mirror as well as the light distribution corresponding to two different positions of the half-mirror. The luminaire (1) comprises a reflector (10) of symmetrical structure with respect to an axis (2) and a neon-type lamp (20), for example, preferably placed on the axis of symmetry (2) at a height depending on the desired level of vertical lighting.

Le réflecteur (10) comprend un demi-miroir (11) qui comporte des crochets (12,13) à ses extrémités et une partie centrale possédant un rayon de courbure prédéterminée en fonction des distributions lumineuses souhaitées. Selon un mode de réalisation, les crochets font partie intégrante du demi-miroir. Il est également possible, à titre d'alternative, de munir un réflecteur courbe de plusieurs crochets, les crochets étant ici des pièces rapportées, bien qu'une telle réalisation soit plus complexe.The reflector (10) comprises a half-mirror (11) which has hooks (12,13) at its ends and a central part having a predetermined radius of curvature in depending on the desired light distributions. According to one embodiment, the hooks are an integral part of the half mirror. It is also possible, as an alternative, to provide a curved reflector with several hooks, the hooks here being parts reported, although such an achievement is more complex.

Ledit réflecteur comprend également des moyens de fixation. Dans le mode de réalisation préféré, un moyen de fixation comporte un logement (14,15) dont une paroi (16,17) forme butée à une partie extérieure d'un crochet (12a,13a). De plus, une partie intérieure (12b) d'un crochet (12) est de dimension sensiblement supérieure à la partie intérieure (13b) correspondante de l'autre crochet. De manière plus générale, les crochets (12,13) sont de dimensions différentes afin de permettre une position relative du demi-miroir (11) par rapport à la lampe (20) qui soit différente pour les deux positions de montage. Ainsi, la forme du demi-miroir lui permet d'être fixé par simple coincement dans les logements en jouant sur son élasticité propre. Il possède en outre une forme géométrique lui permettant de délivrer une première distribution lumineuse pour une première position de montage du demi-miroir dans les logements et une deuxième distribution lumineuse pour une deuxième position de montage du demi-miroir dans les logements, cette deuxième position correspondant à un retournement dudit demi-miroir. Dans le cas où un seul demi-miroir est inséré dans le réflecteur, les distributions lumineuses sont de type asymétrique.Said reflector also includes fixing means. In the mode of preferred embodiment, a fixing means comprises a housing (14,15) including a wall (16,17) forms a stop at an external part of a hook (12a, 13a). In addition, some interior (12b) of a hook (12) is of dimension substantially greater than the part inner (13b) corresponding to the other hook. More generally, the hooks (12,13) are of different dimensions to allow a relative position of the half-mirror (11) relative to the lamp (20) which is different for the two positions of mounting. Thus, the shape of the half-mirror allows it to be fixed by simple wedging in housing by playing on its own elasticity. It also has a form geometric allowing it to deliver a first light distribution for a first mounting position of the half-mirror in the housings and a second light distribution for a second mounting position of the half-mirror in the housing, this second position corresponding to a reversal of said half-mirror. In the case where only one half-mirror is inserted in the reflector, the light distributions are of asymmetric type.

De manière avantageuse, le réflecteur selon l'invention possède un système de repérage. Ce système de repérage consiste en un marquage des extrémités du demi-miroir afin d'indiquer à l'installateur la position de montage du demi-miroir en fonction d'une distribution lumineuse recherchée.Advantageously, the reflector according to the invention has a system of tracking. This marking system consists of marking the ends of the half-mirror to indicate to the installer the mounting position of the half-mirror according to a light distribution sought.

La Fig. la donne l'exemple d'un demi-miroir permettant d'obtenir une première distribution lumineuse (101) de type asymétrique 20/25°. La Fig. 1b montre le demi-miroir après son retournement permettant d'obtenir alors une deuxième distribution lumineuse (102) de type asymétrique 35/40°.Fig. gives the example of a half mirror allowing to obtain a first light distribution (101) of asymmetrical type 20/25 °. Fig. 1b shows the half mirror after its reversal allowing to obtain a second light distribution then (102) asymmetrical type 35/40 °.

Dans le mode de réalisation préféré, la forme géométrique du demi-miroir et la position de la lampe par rapport au réflecteur sont telles que le niveau d'éclairement vertical maximal est supérieur au niveau d'éclairement horizontal maximal. Le luminaire doit en outre satisfaire à des spécifications de défilement mécanique, le défilement mécanique étant l'angle sous lequel un observateur ne voit pas ou plus la lampe. Dans le mode de réalisation préféré, cet angle est au minimum de 20° par rapport au plan de sortie horizontal du luminaire.In the preferred embodiment, the geometric shape of the half mirror and the position of the lamp in relation to the reflector are such that the level of vertical illumination maximum is greater than the maximum horizontal illumination level. The luminaire must in addition to meeting mechanical scrolling specifications, the mechanical scrolling being the angle from which an observer no longer sees the lamp. In the embodiment preferred, this angle is at least 20 ° relative to the horizontal exit plane of the lamp.

Il apparaítra à l'homme du métier que le réflecteur peut posséder plus de deux logements judicieusement disposés de manière à ce que le demi-miroir puisse prendre plusieurs positions différentes et à ce que le réflecteur puisse fournir autant de distributions lumineuses que de configurations possibles.It will appear to those skilled in the art that the reflector can have more than two housings judiciously arranged so that the half-mirror can take several different positions and that the reflector can provide as many distributions as bright as possible configurations.

Les Figs. 2a et 2b représentent un luminaire équipé d'une lampe et de deux demi-miroirs et la distribution lumineuse correspondant à deux positions différentes symétriques des demi-miroirs. La lampe (20) est placée de préférence sur l'axe de symétrie (2) du réflecteur à une hauteur prédéterminée en fonction du niveau d'éclairement souhaité et en tenant compte de l'angle de défilement mécanique. Ladite lampe peut également être située en dehors de l'axe de symétrie, tout en satisfaisant les conditions d'éclairement et d'angle de défilement, de manière à obtenir une distribution lumineuse sensiblement différente.Figs. 2a and 2b represent a luminaire equipped with a lamp and two half-mirrors and the light distribution corresponding to two different symmetrical positions half-mirrors. The lamp (20) is preferably placed on the axis of symmetry (2) of the reflector at a predetermined height depending on the desired level of lighting and taking into account the mechanical travel angle. Said lamp can also be located outside the axis of symmetry, while satisfying the lighting and angle conditions scrolling, so as to obtain a substantially different light distribution.

Dans une première configuration, correspondant à la Fig. 2a, le luminaire est apte à fournir une première distribution lumineuse (201) de type double asymétrique 20/25°. Dans une deuxième configuration, correspondant à la Fig. 2b, le luminaire est apte à fournir une deuxième distribution lumineuse (202) de type double asymétrique 35/40° après retournement des deux demi-miroirs.In a first configuration, corresponding to FIG. 2a, the luminaire is suitable for providing a first light distribution (201) of the asymmetrical double type 20/25 °. In a second configuration, corresponding to FIG. 2b, the luminaire is capable of providing a second light distribution (202) of asymmetrical double type 35/40 ° after reversal of the two half-mirrors.

Les Figs. 3a et 3b représentent un luminaire équipé de deux lampes et d'un demi-miroir et la distribution lumineuse correspondant à deux positions différentes du demi-miroir. Les deux lampes (20) sont placées de préférence de façon symétrique de part et d'autre de l'axe de symétrie (2) du réflecteur à une hauteur prédéterminée fonction du niveau d'éclairement et de l'angle de défilement mécanique.Figs. 3a and 3b represent a luminaire equipped with two lamps and a half-mirror and the light distribution corresponding to two different positions of the half-mirror. The two lamps (20) are preferably placed symmetrically on one side and on the other side of the axis of symmetry (2) of the reflector at a predetermined height depending on the illumination level and mechanical scroll angle.

Dans une première configuration, correspondant à la Fig. 3a, le luminaire est apte à fournir une première distribution lumineuse (301) de type asymétrique 20/25° sensiblement différente de la distribution lumineuse obtenue avec une lampe. Dans une deuxième configuration, correspondant à la Fig. 3b, le luminaire est apte à fournir une deuxième distribution lumineuse (302) de type asymétrique 35/40° après retournement du demi-miroir.In a first configuration, corresponding to FIG. 3a, the luminaire is suitable for providing a first light distribution (301) of asymmetrical type 20/25 ° substantially different from the light distribution obtained with a lamp. In a second configuration, corresponding to FIG. 3b, the luminaire is capable of providing a second light distribution (302) of asymmetrical type 35/40 ° after inversion of the half-mirror.

Les Figs. 4a et 4b représentent un luminaire équipé de deux lampes et de deux demi-miroirs et la distribution lumineuse correspondant à deux positions différentes symétriques des demi-miroirs.Figs. 4a and 4b represent a luminaire equipped with two lamps and two half mirrors and the light distribution corresponding to two different positions symmetrical half-mirrors.

Dans une deuxième configuration, correspondant à la Fig. 4b, le luminaire est apte à fournir une deuxième distribution lumineuse (402) de type double asymétrique 35/40° après retournement des demi-miroirs.In a first configuration, corresponding to FIG. 4a, the luminaire is suitable for provide a first light distribution (401) of the asymmetrical double type 20/25 ° significantly different from the light distribution obtained with a lamp. In second configuration, corresponding to FIG. 4b, the luminaire is capable of providing a second light distribution (402) of asymmetrical double type 35/40 ° after flipping the half-mirrors.

Il apparaítra à l'homme du métier que le luminaire peut posséder plus de deux lampes, lesdites lampes étant disposées, par exemple, de façon symétrique par rapport à l'axe de symétrie (2) et à une distance prédéterminée du plafond du réflecteur. Un tel luminaire possède ainsi une structure modulaire comprenant un réflecteur muni d'au moins un demi-miroir et au moins une lampe.It will appear to those skilled in the art that the luminaire can have more than two lamps, said lamps being arranged, for example, symmetrically with respect to the axis of symmetry (2) and at a predetermined distance from the ceiling of the reflector. Such luminaire thus has a modular structure comprising a reflector provided with at least half a mirror and at least one lamp.
