Description

La présente invention est du domaine de l'éclairage et concerne plus particulièrement une rampe d'éclairage.The present invention is in the field of lighting and relates more particularly to a ramp lighting.

Le brevet US-A-5541 823 propose une rampe d'éclairage pour protéger et supporter des tubes lumineux de type néon qui comprend une section à la base, une section centrale et une section de couverture transparente avec des couvercles aux extrémités pour être utilisé à l'intérieur comme à l'extérieur.US-A-5541 823 patent proposes a ramp to protect and support light tubes of neon type which includes a section at the base, a section central and a transparent cover section with end caps for indoor use like outside.

Dans le brevet EP-A-0142 432, l'invention a pour objet un luminaire clos à tubes fluorescents composé notamment, d'un corps, d'un diffuseur et de deux pièces d'extrémités, ainsi que de moyens d'étanchéité entre le corps, le diffuseur et les pièces d'extrémités. Les pièces d'extrémités portent les douilles des tubes et facultativement, un dispositif d'amorçage. In patent EP-A-0142 432, the invention has for object a closed luminaire with fluorescent tubes composed in particular, a body, a diffuser and two parts ends, as well as sealing means between the body, diffuser and end pieces. Rooms ends carry the tube sockets and optionally, a priming device.

La déposante a déjà développé une rampe d'alimentation électrique décrite dans la demande de brevet européen EP-0.375.623 qui concerne une rampe d'éclairage présentant une succession de paires de contacts électriques comportant au moins deux bandes conductrices superposées ayant à des distances prédéterminées des plaquettes disposées à 90° pour alimenter des séries d'ampoules disposées entre deux contacts adjacents. Les bandes conductrices sont chacune recouvertes par un corps isolant continu sur toute leur surface, de manière à former un empilage dans lequel les bandes conductrices sont totalement isolées entre elles et vers l'extérieur, à l'exclusion des plaquettes de contact.The applicant has already developed a feed ramp electric described in the patent application European EP-0.375.623 concerning a light bar having a succession of pairs of electrical contacts comprising at least two overlapping conductive strips having at predetermined distances platelets arranged at 90 ° to power series of bulbs arranged between two adjacent contacts. Groups conductive are each covered by an insulating body continuous over their entire surface, so as to form a stack in which the conductive strips are completely isolated from each other and outwards, excluding contact pads.

Dans sa demande de brevet européen EP-516.578, la déposante propose que les bandes conductrices soient glissées dans un profilé présentant un dégagement central pour les bandes conductrices et une ouverture laissant passer librement les plaquettes de contact.In its European patent application EP-516,578, the Applicant proposes that the conductive strips be slid into a profile with central clearance for conductive strips and an opening leaving pass the contact pads freely.

Dans la demande de brevet européen EP-0.652.398, la déposante propose un réflecteur en aluminium de section parabolique, disposée de manière continue à l'intérieur du profilé dans le sens de sa longueur et traversée par les plaquettes des contacts électriques, de manière à ce que le foyer de la section parabolique soit disposé au voisinage du centre des ampoules, de manière à constituer un réflecteur linéaire distribuant un faisceau lumineux étroit tout au long de ladite rampe, et permettre l'insertion d'une grille de diffusion disposée dans ledit faisceau lumineux et apte à le diriger et le réfléchir selon une direction préférentielle. In European patent application EP-0.652.398, the Applicant offers a section aluminum reflector parabolic, arranged continuously inside the profiled lengthwise and crossed by electrical contact pads, so that the focus of the parabolic section is placed in the vicinity of the center of the bulbs, so as to constitute a reflector linear distributing a narrow light beam throughout of said ramp, and allow the insertion of a grid of scattering arranged in said light beam and able to direct and reflect it in a preferential direction.

La présente invention concerne une amélioration destinée plus particulièrement à l'éclairage quand pour des raisons pratiques la rampe doit se situer de façon que le faisceau soit orienté vers le haut sans que la rampe n'ait aucune possibilité d'être sous protection et se trouve par conséquent soumise aux intempéries. Pour pallier à cet inconvénient, il faut se pourvoir de rampes comme celle qui est proposée dans cette invention.The present invention relates to an improvement intended more particularly for lighting when for practical reasons the ramp should be located so that the beam is oriented upwards without the ramp having no possibility of being under protection and is by therefore subject to bad weather. To overcome this drawback, you have to have ramps like the one is proposed in this invention.

La rampe selon l'invention comprend un profilé de base présentant deux ailes latérales et une rampe d'alimentation électrique placée à l'intérieur du profilé de base, un profilé transparent en matière plastique appliqué contre les ailes latérales du profilé de base et deux couvercles aptes à collaborer avec le profilé de base et le profilé transparent et placés aux extrémités de la rampe d'éclairage. Elle est caractérisée en ce que le profilé transparent réalisé en matière plastique est coupé selon une longueur légèrement supérieure à celle du profilé de base et présente des bords latéraux qui recouvrent complètement en les entourant les extrémités supérieures des ailes du profilé de base, le profilé transparent reposant aux deux extrémités de la rampe sur l'arête supérieure d'un embout de fermeture fixé contre le profilé de base, les deux couvercles d'extrémité étant appliqués contre l'embout et enferment le profilé transparent et les bords supérieurs du profilé de base.The ramp according to the invention comprises a profile of base with two side wings and a ramp of electrical supply placed inside the profile of base, a transparent applied plastic profile against the side wings of the base profile and two covers suitable for working with the base profile and the transparent profile and placed at the ends of the ramp lighting. It is characterized in that the profile transparent made of plastic material is cut according to a length slightly longer than that of the base profile and has side edges that completely overlap in surrounding them the upper ends of the wings of the basic profile, the transparent profile resting on both ends of the ramp on the upper edge of a nozzle closure fixed against the base profile, both end covers being applied against the nozzle and enclose the transparent profile and the upper edges of the basic profile.

Elle est munie avantageusement de deux profilés latéraux disposés dans le sens de la longueur, couvrant chacun un bord latéral du profilé en matière plastique transparente sur toute sa longueur. Les profilés latéraux présentent chacun une glissière arrondie qui s'enfile dans des fentes arrondies du profilé de base de manière à rester fixe tout au long de la rampe, l'extrémité libre de chaque profilé étant agencé pour plaquer le plastique transparent contre le bord du profilé de base et le maintenir latéralement.It is advantageously provided with two profiles sideways arranged lengthwise, covering each a side edge of the plastic profile transparent over its entire length. Side profiles each have a rounded slide that slides into rounded slots in the base profile so as to remain fixed throughout the ramp, the free end of each profile being arranged to press the transparent plastic against the edge of the base profile and hold it laterally.

Dans un mode de réalisation préféré le profilé en plastique transparent, un polycarbonate ou une matière acrylique à l'occasion, est un plastique extrudé. De même, les deux profilés en aluminium sont aussi extrudés. Ce mode de réalisation permet de concevoir des rampes à longueur modulable en différentes dimensions qui peuvent aller jusqu'à 300 cm.In a preferred embodiment the profile in transparent plastic, polycarbonate or material acrylic on occasion is an extruded plastic. Likewise, the two aluminum profiles are also extruded. This mode to design ramps to length modular in different dimensions that can go up to 300 cm.

Dans ce mode de réalisation, les couvercles en aluminium de la rampe laissent un espace libre aux extrémités de la rampe afin que le plastique transparent et les profilés en aluminium qui sont légèrement plus longs que le profilé de base puissent varier en longueur à cause de la dilatation et du rétrécissement des matériaux avec les variations de températureIn this embodiment, the covers in ramp aluminum leave free space for ends of the ramp so that the transparent plastic and aluminum profiles which are slightly longer than the base profile may vary in length due to the expansion and shrinking of materials with the temperature variations

La rampe peut présenter avantageusement des orifices dans sa partie inférieure de façon à pouvoir évacuer de son intérieur l'eau produite par condensation.The ramp can advantageously have holes in its lower part so that it can evacuate from its interior the water produced by condensation.

Dans un mode de réalisation préféré au moins un des bords supérieurs du profilé de base se termine sous forme inclinée pour faciliter le montage du profilé en plastique transparent. Les embouts de fermeture sont positionnés relativement au profilé de base à l'aide de goujons , les couvercles recouvrant les embouts et étant fixés au moyens de vis vissées dans les alésages du profilé de base. Le profilé de base dispose d'un ergot et d'une rainure permettant à la rampe d'être fixée à un organe de fixation par un système de simple clipsage.In a preferred embodiment at least one of the upper edges of the base profile ends under inclined shape to facilitate mounting of the profile transparent plastic. The end caps are positioned relative to the base profile using studs, the covers covering the end caps and being fixed by means of screws screwed into the profile bores basic. The basic profile has a lug and a groove allowing the ramp to be fixed to a member of fixing by a simple clipping system.

La rampe est avantageusement agencée pour contenir à son intérieur un réflecteur parabolique qui concentrera le faisceau de lumière dans une direction. Elle peut contenir à son intérieur au moins une grille de diffusion pour éviter que la lumière se reflète dans des directions non souhaitables.The ramp is advantageously arranged to contain inside it a parabolic reflector which will concentrate the beam of light in one direction. It can contain its interior at least one diffusion grid to avoid that the light is reflected in directions not desirable.

Le dessin annexé représente, à titre d'exemple non limitatif, une forme d'exécution de l'objet de la présente invention.The accompanying drawing shows, by way of example non-limiting, an embodiment of the subject of the present invention.

La figure 1 est une représentation générale en perspective d'une rampe d'éclairage.Figure 1 is a general representation in perspective of a light bar.

La figure 2 est une coupe transversale de la rampe d'éclairage de la figure 1, selon la ligne II-II.Figure 2 is a cross section of the lighting strip of Figure 1, along line II-II.

La figure 3 est une représentation détaillée de l'embout de fermeture à placer à l'extrémité de la rampe, juste à l'intérieur du couvercle en aluminium.Figure 3 is a detailed representation of the end cap to be placed at the end of the ramp, just inside the aluminum cover.

Dans la représentation générale de la figure 1 la rampe d'éclairage 1 est composée d'un profilé de base 2, d'un profilé en matière plastique 3, d'un couvercle en aluminium 4 placé à chaque extrémité de la rampe 1 et de deux profilés en aluminium 5. Dans la figure 2 est représenté un des orifices 6, qui vont permettre l'évacuation de l'eau produite par condensation à l'intérieur de la rampe. Dans la figure 3 est montré un embout de fermeture 7 avec l'orifice 11 pour un fil conducteur 12 ainsi que les orifices 9 pour les vis de fixation 10. La rampe d'alimentation électrique et le réflecteur parabolique ne sont pas représentés pour simplification du dessin.In the general representation of Figure 1 the light bar 1 is composed of a base profile 2, a plastic profile 3, a cover made of aluminum 4 placed at each end of the ramp 1 and two aluminum profiles 5. In figure 2 is shown one of the holes 6, which will allow the evacuation of water produced by condensation at inside the ramp. In Figure 3 is shown a closure piece 7 with hole 11 for a wire conductor 12 and the holes 9 for the screws fixing 10. The power supply ramp and the parabolic reflector are not shown for simplification of the drawing.

Comme montré dans le dessin, le couvercle en aluminium 4 a une partie supérieure qui dépasse la longueur du profilé de base 2, ainsi que les profilés en aluminium 5, cela pour permettre au profilé en plastique transparent 3 de se dilater lors de variations de température quand la rampe d'éclairage 1 est allumée.As shown in the drawing, the cover in aluminum 4 has an upper part that exceeds the length of base profile 2, as well as aluminum profiles 5, this to allow the transparent plastic profile 3 to expand during temperature variations when the light strip 1 is on.

Le profilé en plastique transparent 3 dans une forme de réalisation avantageuse est fabriqué par extrusion en polycarbonate transparent, genre macrolon ou plexiglas; cela permet de moduler les dimensions de la rampe, de façon qu'on peut aller des longueurs très petites jusqu'aux longueurs de 300 cm. Il comprend une partie centrale avec des bords 31, qui collaborent avec les extrémités supérieures 21a,21b du profilé de base 2, pour finir avec deux ailes 32 qui entourent partiellement lesdites extrémités 21a,21b. La face extérieure des ailes se présente avec des rainures afin de mieux s'adapter aux autres surfaces quand le profilé transparent subit les effets de dilatation et de rétrécissement.The transparent plastic profile 3 in one advantageous embodiment is manufactured by extrusion in transparent polycarbonate, macrolon or plexiglass type; this allows you to adjust the dimensions of the ramp, so that we can go from very small lengths to lengths of 300 cm. It includes a central part with edges 31, which collaborate with the ends upper 21a, 21b of base profile 2, to finish with two wings 32 which partially surround said ends 21a, 21b. The outer face of the wings presents with grooves to better adapt to other surfaces when the transparent profile undergoes dilation and shrinking effects.

Les profilés en aluminium 5 pourront être aussi fabriqués par extrusion et s'adapter aux mêmes dimensions que le profilé en plastique transparent 3. Ces profilés en aluminium 5 se terminent par des glissières arrondies 13 qui collaborent avec les fentes arrondies 12 du profilé de base 2, de manière à s'enfiler dans leurs intérieurs et à rester fixées tout au long de la rampe. Les profilés en aluminium 5 plaquent le profilé en plastique 3 contre les bords du profilé de base 2 et le maintiennent latéralement. Comme conséquence, les profilés en aluminium 5 évitent toute déformation du profilé en plastique 3.Aluminum profiles 5 can also be manufactured by extrusion and adapt to the same dimensions than the transparent plastic profile 3. These aluminum 5 end with rounded rails 13 which collaborate with the rounded slots 12 of the profile base 2, so as to slip into their interiors and remain fixed throughout the ramp. Profiles in aluminum 5 press the plastic profile 3 against the edges of base profile 2 and hold it laterally. As a result, the aluminum profiles 5 avoid any deformation of the plastic profile 3.

Dans la partie inférieure du profilé de base 2, il y aura avantageusement des orifices 6, placés à intervalles réguliers qui permettront l'évacuation de l'eau de condensation cumulée dans la rampe. Ce profilé de base 2 permet l'introduction d'une rampe d'alimentation électrique à son intérieur et pour cela présente dans sa partie inférieure un élargissement 14 pour recevoir ladite rampe qui n'est pas représenté dans le dessin. De même, les rainures 15 servent à glisser un réflecteur parabolique, non représenté, afin de transmettre un faisceau de lumière concentré sur une direction précise. Les rainures 16 servent à placer avantageusement une ou plusieurs grilles de diffusion, non représentées, afin d'éviter que la lumière se reflète d'une façon non souhaitée. Une des ailes 21b du profilé de base présentera un rebord extérieur incliné pour faciliter le montage du profilé en plastique transparent 3.In the lower part of base profile 2, there advantageously there will be holes 6, placed at intervals which will allow the evacuation of water from cumulative condensation in the ramp. This basic profile 2 allows the introduction of an electrical supply ramp inside and for that present in its part lower widening 14 to receive said ramp which is not shown in the drawing. Likewise, grooves 15 are used to slide a parabolic reflector, not shown, in order to transmit a light beam focused on a specific direction. The grooves 16 are used to advantageously place one or more grids not shown, to prevent the light is reflected in an unwanted way. One of the wings 21b of the basic profile will have an outer rim inclined for easy mounting of the plastic profile transparent 3.

Un ergot 17 et une rainure spéciale de la partie 18 permettent à la rampe 1 d'être fixée sur un support non représenté d'une pièce de fixation, par une simple opération de clipsage. Chaque pièce de fixation peut à l'aide d'une vis servir au réglage de l'orientation de l'ensemble dans une direction précise. La rampe peut ainsi être débranchée facilement pour les travaux d'entretien, notamment pour le changement de lampes.A lug 17 and a special groove of the part 18 allow the ramp 1 to be fixed on a non-support represented by a fixing piece, by a simple clipping operation. Each fastener can using a screw to adjust the orientation of the the whole in a specific direction. The ramp can thus be easily disconnected for maintenance work, especially for changing lamps.

Les orifices 8 collaborent avec les orifices correspondants 9 de l'embout de fermeture 7, de manière que l'ensemble, profilé de base 2, embout 7 et couvercles 4, soit fixé par les vis 10.The orifices 8 collaborate with the orifices corresponding 9 of the closure piece 7, so that the assembly, base profile 2, end piece 7 and covers 4, either fixed by screws 10.

Les trous 20 vont collaborer avec les goujons 19 de l'embout de fermeture 7. Cet embout qui comprend les goujons 19 et les orifices 9, a un périmètre adapté au profilé de base 2 et reste solidaire entre ce dernier et les couvercles en aluminium 4. L'orifice 11 servira pour le passage du fil électrique 12.The holes 20 will collaborate with the studs 19 of the closing end piece 7. This end piece which comprises the studs 19 and the orifices 9, has a perimeter adapted to the base profile 2 and remains integral between the latter and aluminum covers 4. Port 11 will be used for passage of the electric wire 12.

La partie supérieure des couvercles 4, permet au profilé en plastique 3 et aux profilés en aluminium 5 de présenter une longueur légèrement supérieure au reste des éléments de la rampe. Cela tient compte du phénomène de dilatation et de rétrécissement qui dans le cas d'une rampe de 300 cm de longueur peut atteindre jusqu'à 15 mm pour un polycarbonate ou un matériel acrylique.The upper part of the covers 4, allows the plastic profile 3 and aluminum profiles 5 of have a length slightly greater than the rest of the elements of the ramp. This takes into account the phenomenon of dilation and narrowing which in the case of a ramp 300 cm in length can reach up to 15 mm for a polycarbonate or acrylic material.

La rampe qui vient d'être décrite se présente ainsi comme une rampe d'éclairage, pratiquement indéformable avec les variations de la température, avec la possibilité d'être modulable pour atteindre une dimension maximale de 300 cm, sans problèmes de condensation à son intérieur, de facile assemblage et très simple à démonter de son support.The ramp which has just been described is presented so like a light bar, practically non-deformable with variations in temperature, with the possibility of being modular to reach a dimension maximum of 300 cm, with no condensation problems with sound interior, easy to assemble and very simple to disassemble of its support.
