Description

Domaine techniqueTechnical area

L'invention a pour objet un luminaire asymétrique polyvalent réalisé à partir d'un profilé extrudé coupé à la dimension désirée.The invention relates to a versatile asymmetric luminaire made from an extruded profile cut to the desired size.

Etat de la techniqueState of the art

Le luminaire selon l'invention est destiné à former une rampe d'éclairage qui pourra être utilisée horizontalement ou verticalement. La déposante a déjà développé un grand nombre de rampes d'éclairage d'alimentation électrique décrites dans les brevets européens n° EP0375623 , EP0516578 et EP0652398 . Ces rampes d'éclairage peuvent contenir des tubes néon d'une certaine longueur ou une succession d'ampoules disposées le long de deux bandes conductrices superposées présentant une succession de paires de contacts électriques permettant de retenir les ampoules. La rampe d'éclairage ou le luminaire peut être réalisé à partir d'un profilé allant préférablement jusqu'à six mètres de longueur et coupé selon les besoins. Les bandes conductrices portant les ampoules seront avantageusement glissées dans des rails s'étendant sur toute la longueur du profilé et faisant partie de celui-ci. Dans les brevets mentionnés ci-dessus, l'éclairage réalisé par les tubes néon ou par la succession d'ampoules est un éclairage perpendiculaire par rapport à l'ouverture du luminaire, c'est à dire que le faisceau lumineux sortant du luminaire est symétrique par rapport à celui-ci. Il existe cependant sur le marché des luminaires réalisés à partir d'un profilé extrudé permettant de diriger un faisceau lumineux asymétrique au moyen de réflecteurs judicieusement disposés dans le bâti du luminaire. Ces types de luminaire ne donnent cependant pas des résultats très satisfaisants étant entendu qu'ils ne permettent pas de concentrer le faisceau lumineux à l'endroit où celui-ci est désiré. D'autre part, ils sont de conception relativement compliquée, et nécessitent des pièces additionnelles permettant de disposer les réflecteurs de manière adéquate.The luminaire according to the invention is intended to form a lighting ramp which can be used horizontally or vertically. The applicant has already developed a large number of power supply lighting ramps described in European patents no. EP0375623 , EP0516578 and EP0652398 . These lighting ramps may contain neon tubes of a certain length or a succession of bulbs arranged along two superimposed conductive strips having a succession of pairs of electrical contacts. to hold the bulbs. The lighting ramp or luminaire can be made from a profile preferably up to six meters in length and cut as needed. The conductive strips carrying the bulbs will advantageously be slid into rails extending over the entire length of the profile and forming part of it. In the patents mentioned above, the lighting produced by the neon tubes or by the succession of bulbs is a lighting perpendicular to the opening of the luminaire, that is to say that the light beam coming out of the luminaire is symmetrical in relation to this one. However, there are luminaires on the market made from an extruded profile for directing an asymmetric light beam by means of reflectors judiciously arranged in the luminaire frame. These types of luminaire, however, do not give very satisfactory results on the understanding that they do not allow the light beam to be concentrated where it is desired. On the other hand, they are of relatively complicated design, and require additional parts to arrange the reflectors adequately.

Un exemple de ce type de luminaire est décrit dans le brevet US 5,032,958 .An example of this type of luminaire is described in the patent US 5,032,958 .

La demande de brevet publiée sous le numéro JP 2000-348507 décrit un autre type de luminaire projetant un faisceau lumineux asymétrique dans lequel un réflecteur parabolique, formé d'une seule pièce, est disposé à l'intérieur d'un bâti sensiblement parallélépipédique. Toutefois, l'assemblage d'un tel luminaire se révèle délicat, non seulement du point de vue du montage du réflecteur dans le bâti, mais également pour la mise en place des éléments éclairants après le montage du réflecteur.The patent application published under the number JP 2000-348507 discloses another type of luminaire projecting an asymmetric light beam in which a parabolic reflector, formed in one piece, is disposed within a substantially parallelepiped frame. However, the assembly of such a luminaire is delicate, not only from the point of view of mounting the reflector in the frame, but also for the establishment of illuminating elements after mounting the reflector.

The upper face 2, as well as the side faces 3 and 4 have grooves 6, 7 and 8 which will as explained later to fix the profile against a wall, a ceiling or in a recessed structure intended to serve as housing. The four lateral faces 2, 3, 4 and 5 of the profile 1 are in the form of a rectangular parallelepiped which can be closed at its ends by a plate 9 as shown in FIG. Fig. 1 by means of the end screws 10. The end screws are introduced into housings 11 extending over the entire length of the profile 1.

Les rainures 6, 7 et 8 permettront de fixer ou de maintenir le profilé contre un mur, un plafond ou à l'intérieur d'une structure comme représenté dans la fig.3. Une ouverture 12 est prévue sur une bonne partie de la face inférieure 5, de manière à libérer une grande partie de ladite face 5 et permettre au faisceau lumineux engendré depuis le volume intérieur de l'enveloppe du luminaire de sortir de la structure. A l'endroit de l'ouverture 12, le luminaire présentera des rainures 13 et 14 permettant de glisser un filtre, une grille ou un verre acrylique 15 (fig. 2 et 3). L'ouverture 12 est adjacente à deux parois intérieures 16 et 17 s'étendant dans le volume intérieur de l'enveloppe et définissant en coupe une portion d'ellipse ou de parabole. Les parois intérieures 16 et 17 sont disjointes dans la région du sommet de l'ellipse ou de la parabole et présentent préférablement, dans cette région, des rainures 18, 19 destinées à recevoir un réflecteur 20, de forme arrondie, destiné à fermer le sommet de l'ellipse ou de la parabole. Comme représenté dans les figures du dessin, le réflecteur 20 forme avec les parois intérieures 16 et 17 du profilé une ellipse ou une parabole qui s'ouvrira vers l'ouverture 12 sur la face inférieure 5 du luminaire 1.The grooves 6, 7 and 8 will fix or maintain the profile against a wall, ceiling or inside a structure as shown in the fig.3 . An opening 12 is provided on a good part of the lower face 5, so as to release a large part of said face 5 and allow the light beam generated from the interior volume of the luminaire envelope to exit the structure. At the location of the opening 12, the luminaire will have grooves 13 and 14 for sliding a filter, a grid or an acrylic glass 15 (FIG. Fig. 2 and 3 ). The opening 12 is adjacent to two inner walls 16 and 17 extending in the interior volume of the envelope and defining in section a portion of ellipse or parabola. The inner walls 16 and 17 are disjoint in the region of the top of the ellipse or parabola and preferably have, in this region, grooves 18, 19 for receiving a reflector 20, of rounded shape, intended to close the top of the ellipse or the parable. As shown in the figures of the drawing, the reflector 20 forms with the walls 16 and 17 of the profile an ellipse or a parabola which will open towards the opening 12 on the lower face 5 of the luminaire 1.

On remarque que la parabole ou l'ellipse formée par les parois intérieures 16, 17 et le réflecteur 20 présente un grand axe qui forme un angle d'approximativement quarante cinq degrés par rapport au plan de l'ouverture. Il est évident pour l'homme du métier que suivant l'utilisation que l'on entend faire du luminaire, l'axe de l'ellipse ou de la parabole peut varier dans une fourchette de trente à soixante degrés par rapport à l'horizontale ou par rapport au plan de l'ouverture du profilé 1.Note that the parabola or ellipse formed by the inner walls 16, 17 and the reflector 20 has a major axis which forms an angle of approximately forty five degrees relative to the plane of the opening. It is obvious to those skilled in the art that according to the intended use of the luminaire, the axis of the ellipse or parabola may vary within a range of thirty to sixty degrees from the horizontal or with respect to the plane of the opening of the profile 1.

Le profilé extrudé 1 est réalisé de préférence en métal, par exemple en aluminium et pourra être extrudé et éloxé au naturel ou en couleur, ou encore en blanc. Il se présentera sous la forme d'une structure allongée d'une longueur allant jusqu'à six mètres déterminée par des exigences de transport et pourra être coupé par l'utilisateur selon les dimensions désirées. Comme visible sur la fig. 1 il pourra être fermé à ses extrémités par des plaques 9 au moyen des vis 10.The extruded section 1 is preferably made of metal, for example aluminum and can be extruded and eloxed natural or in color, or in white. It will be in the form of an elongated structure of up to six meters length determined by transport requirements and can be cut by the user to the desired dimensions. As visible on the Fig. 1 it can be closed at its ends by plates 9 by means of screws 10.

Dans la fig. 2, le luminaire est appliqué contre un mur 30, de manière à surmonter un miroir 31 représenté dans la fig. 2. Le profilé pourra être glissé dans un rail non représenté fixé préalablement contre le mur 30, si cela est possible. Alternativement, le profilé 1 pourra être fixé au mur au moyen d'un support non représenté fixé au mur 30 et fixé par exemple dans la rainure 7.In the Fig. 2 , the luminaire is applied against a wall 30, so as to overcome a mirror 31 shown in FIG. Fig. 2 . The profile can be slid into a not shown rail previously fixed against the wall 30, if this is possible. Alternatively, the profile 1 can be fixed to the wall by means of a not shown support fixed to the wall 30 and fixed for example in the groove 7.

Un exemple de fixation du profilé 1 est représenté dans la fig. 3, où des pattes de fixation 32 se présentant chacune sous la forme d'un L sont préalablement fixées contre le luminaire au moyen des vis 33 et des écrous 34. Les supports 32 s'appuient sur la partie intérieure d'un faux plafond 35 après qu'une ouverture ait été pratiquée dans le faux plafond et que le luminaire ait été introduit dans le sens vertical pour subir ensuite une rotation de quatre-vingt dix degrés à l'intérieur de l'ouverture et prendre la position représentée dans la fig.3.An example of attachment of the profile 1 is shown in the Fig. 3 , where fixing lugs 32 each in the form of an L are previously fixed against the luminaire by means of the screws 33 and nuts 34. The supports 32 rest on the inner part of a false ceiling 35 after that an opening was made in the false ceiling and that the luminaire was introduced in the vertical direction to then undergo a rotation of ninety degrees within the opening and take the position represented in the fig.3 .

Le réflecteur 20 présentera une longueur sensiblement égale à la longueur du profilé et sera introduit dans les rainures 18 et 19 placées aux sommets des parois intérieures 16 et 17 du profilé. Comme représenté dans la fig. 2, le profilé 1 sera utilisé en liaison avec un ou plusieurs tubes fluorescents 22 maintenus à leurs extrémités par des douilles montées sur des supports 23, eux-mêmes glissés dans un rail 24 s'étendant à l'intérieur du profilé 1, au-dessus du réflecteur 20. Si plusieurs néons sont utilisés dans le même profilé, il est évident que des perforations permettant' de passer les supports 23 devront être prévues dans le réflecteur 20.The reflector 20 will have a length substantially equal to the length of the profile and will be introduced into the grooves 18 and 19 placed at the vertices of the inner walls 16 and 17 of the profile. As represented in the Fig. 2 , the profile 1 will be used in conjunction with one or more fluorescent tubes 22 held at their ends by sockets mounted on supports 23, themselves slid in a rail 24 extending inside the profile 1, above of the reflector 20. If several neons are used in the same profile, it is obvious that perforations to pass the supports 23 must be provided in the reflector 20.

Dans le mode d'exécution des fig. 3, 4 et 5, les éléments d'éclairage destinés à être utilisés dans le profilé 1 sont disposés sur une bande d'alimentation 25 formée de deux conducteurs plats isolés en aimantant une succession de contacts électriques 26 supportant des ampoules 27 fixées sur la bande, le tout étant glissé dans la rainure longitudinale 24. Dans ce cas, le réflecteur 20 présentera une succession de paires de perforations 28 destinées à recevoir les contacts 26 qui sont préalablement introduits par le dessous sur le réflecteur 20, les bandes d'alimentation 25 étant appliquées contre le dessous du réflecteur 20. Le tout est ensuite glissé dans les rainures 18, 19 des parois intérieures 16 et 17 du profilé, les bandes conductrices étant introduites dans la rainure 24 après que le réflecteur 20 ait subit une rotation par rapport aux bandes conductrices 25. Dès que les bandes conductrices 25 avec les contacts 26 auront été glissés avec le réflecteur 20 dans les rainures 18, 19 et 24, les lampes 27 pourront être mises en place et elles se trouveront alors au dessous du réflecteur, de manière à ce que les lampes soient disposées sur le grand axe de l'ellipse ou de la parabole dans une position adjacente au réflecteur 20 correspondant sensiblement au foyer de l'ellipse ou de la parabole.In the execution mode of Fig. 3, 4 and 5 , the lighting elements for use in the section 1 are arranged on a power strip 25 formed of two insulated flat conductors by magnetizing a succession of electrical contacts 26 supporting bulbs 27 fixed on the strip, the whole being slipped in the longitudinal groove 24. In this case, the reflector 20 will have a succession of pairs of perforations 28 intended to receive the contacts 26 which are previously introduced from below onto the reflector 20, the supply strips 25 being applied against the underside of the reflector 20. The whole is then slid into the grooves 18, 19 of the inner walls 16 and 17 of the profile, the conductive strips being introduced into the groove 24 after the reflector 20 is rotated relative to the conductive strips 25. As soon as the conductive strips 25 with the contacts 26 have been slid with the reflector 20 into the grooves 18, 19 and 24, the lamps 27 can be put in place and they then will find below the reflector, so that the lamps are disposed on the major axis of the ellipse or parabola in a position adjacent to the reflector 20 corresponding substantially to the focus of the ellipse or parabola.

Dans le cas représenté dans la fig.2 où un luminaire de quatre vingt watts est placé à environ deux mètres de hauteur, l'éclairage obtenu à une distance de soixante centimètres de la paroi sera de cent soixante lux à dix centimètres du réflecteur, mille huit cents lux à cinquante centimètres du réflecteur (position correspondant approximativement à la tête d'une personne debout), mille lux à un mètre au dessous du réflecteur et six cent trente lux à un mètre cinquante du réflecteur. Une personne debout à soixante centimètres d'éloignement par rapport au réflecteur sera ainsi parfaitement éclairée. De même, toujours à soixante centimètres d'un miroir, on aura avec un luminaire fluorescent T5 de quatre vingt watts à deux mille sept cents degrés Kelvin, le luminaire étant placé à vingt centimètres du miroir et à deux mètres environ au dessus, un éclairage de trois cent soixante lux à dix centimètres du luminaire, mille six cents lux à cinquante centimètres, mille deux cents lux à un mètre et sept cent vingt lux à un mètre cinquante au dessous du luminaire.In the case represented in fig.2 where a luminaire of eighty watts is placed at a height of about two meters, the illumination obtained at a distance of sixty centimeters from the wall shall be from one hundred and sixty lux to ten centimeters from the reflector, one thousand eight hundred lux to fifty centimeters from the reflector ( corresponding position approximately at the head of a person standing), a thousand lux at one meter below the reflector and six hundred and thirty lux at one meter and fifty meters from the reflector. A person standing sixty centimeters away from the reflector will be perfectly illuminated. In the same way, always sixty centimeters from a mirror, we will have with a fluorescent fixture T5 of eighty watts at two thousand seven hundred degrees Kelvin, the luminaire being placed at twenty centimeters of the mirror and at about two meters above, a lighting from three hundred and sixty lux to ten centimeters from the luminaire, one thousand six hundred lux to fifty centimeters, one thousand two hundred lux to one meter and seven hundred and twenty lux to one meter and a half below the luminaire.

Dans le cas où l'on utilise le luminaire muni d'un tube fluorescent T5 de quatre vingt watts, deux mille sept cents degrés Kelvin, utilisé pour éclairer une paroi, le luminaire étant placé à environ deux mètre quarante de hauteur et éloigné du mur de quatre vingt centimètres, on aura contre la paroi un éclairage de trois cent vingt lux à dix centimètres au dessous du luminaire, huit cent trente lux à cinquante centimètres au dessous du luminaire, six cent quatre vingt lux à un mètre au dessous du luminaire, quatre cent vingt lux à cent cinquante centimètres et cent quatre vingt lux à deux cents centimètres. On remarque avec les deux exemples mentionnés ci-dessus que le luminaire peut être utilisé soit en éclairage direct, soit en éclairage indirect contre une paroi pour obtenir une luminosité tout à fait satisfaisante avec une lampe de seulement quatre vingt watts. Les parois 16 et 17 et le réflecteur permettent de diriger un faisceau lumineux d'une manière extrêmement efficace.In the case where the luminaire is equipped with a fluorescent tube T5 of eighty watts, two thousand seven hundred degrees Kelvin, used to illuminate a wall, the luminaire being placed at about two meters forty height and away from the wall eighty centimeters, there will be against the wall a lighting of three hundred and twenty lux ten centimeters below the luminaire, eight hundred thirty lux to fifty centimeters below the luminaire, six hundred and eighty-five lux to one meter below the luminaire, four hundred and twenty lux to one hundred and fifty centimeters, and one hundred and eighty lux to two hundred centimeters. It is noted with the two examples mentioned above that the luminaire can be used either in direct lighting or in indirect lighting against a wall to obtain a brightness quite satisfactory with a lamp of only eighty watts. The walls 16 and 17 and the reflector make it possible to direct a light beam in an extremely efficient manner.

Le luminaire sera avantageusement réalisé dans un aluminium éloxé naturel pour un éclairage lèche-mur ou un éclairage direct sur une personne par exemple dans une salle de bains.The luminaire will advantageously be made of natural anodized aluminum for wall-wiper lighting or direct lighting on a person for example in a bathroom.

Comme mentionné plus haut la paroi inférieure 5 du luminaire présente des encoches 13 et 14 permettant de monter un filtre, une grille et/ou un verre acrylique fermant l'enveloppe du luminaire. Les ampoules utilisées et fixées sur la borne conductrice sont des ampoules navettes à incandescence, des ampoules XENON ou des LED. Alternativement les luminaires peuvent être équipés de tubes néon de tout type.As mentioned above, the lower wall 5 of the luminaire has notches 13 and 14 for mounting a filter, a grid and / or an acrylic glass closing the envelope of the luminaire. The bulbs used and fixed on the conductive terminal are incandescent shuttle bulbs, XENON bulbs or LEDs. Alternatively the luminaires can be equipped with neon tubes of any type.

Finalement les éléments d'éclairage seront placés sur l'axe de l'ellipse ou de la parabole entre une position très rapprochée par rapport au sommet du réflecteur et le foyer de l'ellipse ou de la parabole.Finally the lighting elements will be placed on the axis of the ellipse or parabola between a position very close to the top of the reflector and the focus of the ellipse or parabola.
