Description

L'invention a pour objet un élément d'éclairage selon le préambule de la revendication 1. De tels éléments d'éclairage sont bien connus, voir, par exemple, les éléments d'éclairage du type lampe navette ou présentant des contacts de type à boucle rigide. L'invention a également pour objet un luminaire selon le préambule de la revendication 15. Un tel luminaire est par exemple connu du document WO-A-01/07828 .The invention relates to a lighting element according to the preamble of claim 1. Such lighting elements are well known, see, for example, lighting elements of the shuttle lamp type or having type-to-type contacts. rigid loop. The invention also relates to a luminaire according to the preamble of claim 15. Such a luminaire is for example known from the document WO-A-01/07828 .

Les lumières blanches destinées à l'éclairage peuvent présenter de faibles composantes de couleurs tirant le plus souvent sur le rouge, le jaune, voire sur le bleu. Cependant, lorsqu'il s'agit d'éclairage, un élément de ce type doit obligatoirement fournir une composante de lumière blanche important.White lights for lighting may have weak color components, most often red, yellow or blue. However, when it comes to lighting, an element of this type must necessarily provide a significant white light component.

Depuis une vingtaine d'années sont apparues sur le marché des nouvelles sources de lumière appelées LED's. Ces LED's, qui n'ont habituellement pas une grande luminosité sont utilisées pour faire du balisage sur les routes, sur les murs, ou sur des panneaux d'indication. Cette fonction de balisage et d'indication est habituellement réalisée avec des LED's de couleurs, soit des LED's rouges, bleues, vertes, jaunes, etc. Ces balisages sont réalisés pour indiquer des cheminements ou des obstacles et sont de faible intensité lumineuse, de manière à ne pas éblouir. Les LED's utilisées pour le balisage offrent l'avantage d'avoir, contrairement aux ampoules de toutes sortes, une durée de vie extrêmement longue, de l'ordre de 100'000 heures d'utilisation, Cette longue durée de vie est un avantage important, car les changements ou remplacements de lampes défectueuses ou d'ampoules ne sont alors plus nécessaires.For about twenty years, new light sources called LEDs have appeared on the market. These LED's, which usually do not have a high brightness, are used to mark roads, walls, or signs. This markup and indication function is usually performed with colored LEDs, ie red, blue, green, yellow LEDs, etc. These markings are made to indicate paths or obstacles and are of low light intensity, so as not to dazzle. LEDs used for markup offer the advantage of having, unlike light bulbs of all kinds, an extremely long life, of the order of 100'000 hours of use, This long service life is an important advantage, because the changes or replacements of defective lamps or bulbs are not then more necessary.

Le but de l'invention est de proposer un élément d'éclairage, par conséquent un élément émettant de la lumière blanche présentant cette longue durée d'utilisation, cet élément d'éclairage peut être avantageusement utilisé dans un luminaire muni d'une ou de plusieurs paires de bornes d'alimentation électriques régulièrement disposées à l'intérieur, le long du luminaire. Ces luminaires ou rails d'éclairage sont généralement utilisés pour réaliser des éclairages de surface sur de grandes longueurs et sont composés d'unités pouvant aller jusqu'à 6 mètres de long, qui placées à la suite l'une de l'autre permettent d'éclairer de grandes longueurs, par exemple des plafonds, des façades, etc. Les rails d'éclairage, particulièrement adaptés à recevoir les éléments d'éclairage faisant l'objet de la présente invention sont décrits dans le brevet européen No 652 398 ou dans la demande de brevet PCT/CH 97/00317 , appartenant tous les deux au groupe Agabekov également titulaire du présent brevet. L'alimentation électrique des rails mentionnés ci-dessus est réalisée à partir de rampes d'alimentation, également protégées dans les brevets européens No 375 623 et 516 578 , également au nom du groupe Agabekov. Ces rampes d'alimentation électrique sont glissées à l'intérieur des rails d'éclairage et présentent des paires de bornes d'alimentation placées à la suite et à égale distance les unes des autres le long de la rampe. Les éléments d'éclairage faisant l'objet de la présente invention sont avantageusement placés le long des rampes entre les paires de bornes d'alimentation. On comprend immédiatement que, le rail étant installé et muni des éléments d'éclairage selon l'invention, il aura une très longue durée de vie et plus aucun entretien ne sera nécessaire.The object of the invention is to propose a lighting element, therefore a white light emitting element having this long duration of use, this lighting element can be advantageously used in a luminaire equipped with one or several pairs of power supply terminals regularly arranged inside, along the luminaire. These luminaires or lighting rails are generally used for surface lighting over long lengths and are composed of units up to 6 meters long, placed one after the other to to illuminate great lengths, eg ceilings, facades, etc. The lighting rails, particularly adapted to receive the lighting elements forming the subject of the present invention are described in the European Patent No 652,398 or in the patent application PCT / CH 97/00317 , both belonging to the group Agabekov also holder of this patent. The power supply of the rails mentioned above is made from feed ramps, also protected in the European patents No 375,623 and 516,578 , also on behalf of the Agabekov group. These power supply ramps are slid inside the light rails and have pairs of power terminals placed after and equidistant from each other along the ramp. The lighting elements forming the subject of the present invention are advantageously placed along the ramps between the pairs of supply terminals. It is immediately understood that, the rail being installed and provided with the lighting elements according to the invention, it will have a very long life and no maintenance will be necessary.

Dans le cas où les LED's sont portées par une plaquette, cette dernière comprend, à une de ses extrémités, des contacts électriques reliés aux LED's et à des contacts électriques de l'élément d'habillage de l'ampoule. Ces derniers sont ensuite destinés à être connectés à des bornes d'alimentation électriques externes à l'ampoule pour en permettre le fonctionnement.In patents US 5,655,830 and US 5,726,535 Lighting elements in the form of bulbs with a screw-on or bayonet base are described.

Cette rainure est destinée à recevoir un réflecteur non représenté et/ou un verre de protection. Le rail d'éclairage ou luminaire représenté dans les figures 2 et 3 est un rail semblable au rail décrit dans le brevet européen No 652 398 ou dans le PCT/CH 97/00317 également au nom de la titulaire.The embodiment of the lighting element 1 shown in FIG. figure 1 has a printed circuit board 2, on which are placed 2 rows of 6 LED diodes 3, respectively 4, above and below the plate. These LEDs 3 and 4 are connected in series on conductive portions not shown of the plate connected at each of their ends to circular contacts 5,6 identical to the contacts normally used with shuttle lamps. Contacts 5 and 6 are (see also figure 2 and 3 ) introduced into bores 7, respectively 8, formed in supply terminals 9, 10, connected to insulated conductors 11, 12, forming a power supply ramp 13 of the same type as the power supply ramps described in the European Patents No 375,623 or no 516,578 . These ramps make it possible to energize a succession of lighting elements and are intended to be introduced into a groove 14 of a lighting rail 15 in which is provided at least one groove 18, 19 placed on the upper edge of the wings 16 and 17. This groove is intended to receive a reflector not shown and / or a protective glass. The lighting rail or luminaire represented in the Figures 2 and 3 is a rail-like rail described in European Patent No 652,398 or in the PCT / CH 97/00317 also on behalf of the licensee.

Les LED's représentées dans le mode d'exécution des figures 1 à 3 sont des LED's NICHIA SMD 120°/60° 066 cd et sont réalisées pour êtres mises sous tension de 4 volts par unité. L'élément 1 des figures 1 à 3 sera par conséquent mis sous une tension de 24 volts, ce qui correspond à une tension normalement utilisée dans les rails d'éclairage du type représenté dans les figures 2 et 3. Vu les diodes utilisées, le courant qui traversera l'élément sera d'environ 50mA. Les LED's, dont la spécification est donnée ci-dessus émettent une lumière blanche et dans le cas où l'élément d'éclairage présente une rangée supérieure de 6 LED's, une rangée inférieure également de 6 LED's et qu'un réflecteur parabolique a été placé dans le rail d'éclairage, la luminosité par unité de longueur fournie par le rail est parfaitement satisfaisante.The LEDs represented in the execution mode of the Figures 1 to 3 are LEDs NICHIA SMD 120 ° / 60 ° 066 cd and are made to be energized 4 volts per unit. Element 1 of Figures 1 to 3 will therefore be put under a voltage of 24 volts, which corresponds to a voltage normally used in lighting rails of the type shown in the Figures 2 and 3 . Given the diodes used, the current that will pass through the element will be about 50mA. The LEDs, whose specification is given above, emit a white light and in the case where the lighting element has a top row of 6 LEDs, a lower row also of 6 LED's and a parabolic reflector has been placed in the lighting rail, the brightness per unit length provided by the rail is perfectly satisfactory.

Dans la variante de la figure 4, l'élément d'éclairage 21 présente, de même que l'élément 1 de la figure 1, une platine de circuit imprimé 2, sur laquelle sont montées deux rangées de 6 LED's 22, respectivement 4, les LED's 22 et 4 étant placées au dessus et au dessous de la platine 2. Les LED's 4 sont du même type que celles décrites en regard de la figure 1 et sont des LED's NICHIA SMD 120°/60° 0,66 cd branchées en série sur les lignes conductrices non représentées de la platine 2 et des LED's NICHIA de 5mm, diamètre de 5,6 cd/20°. Comme dans le mode d'exécution des figures 1 à 3, ces LED's sont branchées sur des parties conductrices de la platine reliées chacune à leurs extrémités à des contacts 23, 24 se présentant sous forme de boucle. Les contacts 23, 24 se présentant sous forme de boucle sont clipsés sur des cavaliers 25, 26, eux-mêmes placés par friction sur les bornes d'alimentation 9, 10 au moyen des cadres 27, 28. Les cavaliers 25, 26 avec leurs parties supérieures en forme de pince destinées à recevoir les boucles et leurs cadres 28 sont décrits en détail dans le brevet européen No 516 578 et les bornes d'alimentation 9, 10 sont de même que dans le mode d'exécution des figures 1 à 3 reliées à des conducteurs isolés 11, 12 formant la rampe d'alimentation électrique. La rampe d'alimentation 13 est également décrite dans le brevet européen No 516 578 et est destinée à mettre sous tension une succession d'éléments d'éclairage placés le long de la rampe 13. Les cavaliers 26, de même que les bornes d'alimentation 9, 10 qui les supportent traversent un réflecteur parabolique 29 glissé dans les rainures 18 et 19 des ailes 16 et 17 d'un rail d'éclairage 15 semblable à celui du mode d'exécution des figures 1 à 3. La rampe isolante 13 est introduite dans une rainure 14 du rail d'éclairage avec le réflecteur parabolique 29 maintenu latéralement dans les rainures 18 et 19 des ailes 16 et 17 du rail d'éclairage. Le rail d'éclairage 15 est comme celui du mode d'exécution des figures 1 à 3 très semblable au rail d'éclairage décrit dans le brevet européen No 652 398 ou dans le PCT/CH 97/00317 . Finalement, les cavaliers 25 et 26 montés sur les bornes d'alimentation 9 et 10 sont entourés par des gaines de protection isolante 30 et 31 traversant également le réflecteur parabolique 29. Le rail d'éclairage des figures 4 et 6 présente encore à la partie supérieure des ailes 16 et 17 une rainure 32, 33 destinée à recevoir un filtre ou un verre de protection.In the variant of the figure 4 , the lighting element 21 presents, as well as the element 1 of the figure 1 a printed circuit board 2, on which are mounted two rows of 6 LEDs 22, respectively 4, the LEDs 22 and 4 being placed above and below the plate 2. The LEDs 4 are of the same type as those described in FIG. look at the figure 1 and are LEDs NICHIA SMD 120 ° / 60 ° 0.66 cd connected in series on the conductive lines not shown of the plate 2 and LED's NICHIA of 5mm, diameter of 5.6 cd / 20 °. As in the execution mode of Figures 1 to 3 these LED's are connected to conductive parts of the plate each connected at their ends to contacts 23, 24 in the form of a loop. The contacts 23, 24 in the form of a loop are clipped on jumpers 25, 26, themselves frictionally placed on the supply terminals 9, 10 by means of the frames 27, 28. The jumpers 25, 26 with their gripper-shaped upper parts for receiving the loops and their frames 28 are described in detail in European Patent No 516,578 and the supply terminals 9, 10 are the same as in the embodiment of the Figures 1 to 3 connected to insulated conductors 11, 12 forming the power supply ramp. Feed ramp 13 is also described in European Patent No 516,578 and is intended to energize a succession of lighting elements placed along the ramp 13. The jumpers 26, as well as the power supply terminals 9, 10 which support them pass through a parabolic reflector 29 slid in the grooves 18 and 19 of the wings 16 and 17 of a lighting rail 15 similar to that of the embodiment of the Figures 1 to 3 . The insulating ramp 13 is introduced into a groove 14 of the lighting rail with the parabolic reflector 29 held laterally in the grooves 18 and 19 of the wings 16 and 17 of the lighting rail. The lighting rail 15 is like that of the embodiment of the Figures 1 to 3 very similar to the lighting rail described in European Patent No 652,398 or in the PCT / CH 97/00317 . Finally, the jumpers 25 and 26 mounted on the supply terminals 9 and 10 are surrounded by insulating protective sleeves 30 and 31 also passing through the parabolic reflector 29. The lighting rail Figures 4 and 6 still has at the upper part of the wings 16 and 17 a groove 32, 33 for receiving a filter or a protective glass.

De même que dans le mode d'exécution des figures 1 à 3, les éléments d'éclairage 1 et 21 sont positionnés de manière à ce qu'ils soient placés au foyer de la surface parabolique du réflecteur. On a ainsi un taux de réflexion maximum et un faisceau réfléchi sensible.As in the mode of execution of Figures 1 to 3 , the lighting elements 1 and 21 are positioned so that they are placed at the focus of the parabolic surface of the reflector. There is thus a maximum reflection rate and a sensitive reflected beam.

Dans la variante de la figure 7, le luminaire ou rail d'éclairage représenté en coupe est réalisé à partir d'un profilé extrudé 35 présentant deux ailes latérales 36 et 37. Au sommet des ailes latérales 36 et 37 est placé un couvercle transparent en matière plastique 38 serré sur les bords supérieurs des ailes par des glissières de positionnement 39, 40. Aux extrémités libres du profilé sont placés des couvercles non représentés destinés à enfermer de manière étanche le luminaire qui ne sera pas décrit en détail. En effet, ce luminaire est l'objet de la demande PCT/CH 97/00317 et a été utilisé jusqu'à ce jour avec des éléments d'éclairage traditionnels, notamment des lampes navettes ou des lampes Xenon. Dans la version représentée dans la figure 7, le luminaire est équipé d'éléments d'éclairage 21 identiques à l'élément de la figure 4. Ces éléments 21 présentent sur le dessus de la platine six LED's 22 à éclairage direct présentant un faisceau fermé à 20°. Au dessous de la platine l'élément 21 présente six LED's 4 présentant un faisceau de lumière ouvert à 60°, respectivement 120°. Selon des coordonnées orthogonales comme représenté dans le dessin, l'élément est positionné dans le luminaire 35, de manière à ce que les LED's soient placées au foyer 41 du réflecteur parabolique 42. Ainsi, le large faisceau de lumière émis par les LED's est réfléchi vers le haut selon une composante verticale par le réflecteur 42 et la totalité de la lumière émise et réfléchie s'ajoute au faisceau direct émis par les LED's 22. Le résultat obtenu à l'aide des éléments 21 placés dans le luminaire 35 est absolument inattendu et la lumière fournie par le luminaire est suffisante pour éclairer des surfaces, tel que des façades, des plafonds, etc. Ce fait n'était pas évident car l'intensité lumineuse des LED's est relativement faible par rapport à celle des ampoules conventionnelles.In the variant of the figure 7 , the luminaire or lighting rail shown in section is made from an extruded profile 35 having two lateral wings 36 and 37. At the top of the lateral wings 36 and 37 is placed a transparent plastic cover 38 tight on the edges upper wings by positioning slides 39, 40. At the free ends of the profile are placed not shown covers for sealingly enclosing the luminaire which will not be described in detail. Indeed, this luminaire is the object of the request PCT / CH 97/00317 and has been used to date with traditional lighting elements, such as shuttle lamps or Xenon lamps. In the version represented in the figure 7 , the luminaire is equipped with lighting elements 21 identical to the element of the figure 4 . These elements 21 have on the top of the plate six LEDs 22 with direct light having a beam closed at 20 °. Under the plate element 21 has six LEDs 4 having a beam of light open at 60 °, respectively 120 °. According to orthogonal coordinates as shown in the drawing, the element is positioned in the luminaire 35, so that the LED's are placed at the focus 41 of the parabolic reflector 42. Thus, the broad beam of light emitted by the LED's is reflected. upwardly in a vertical component by the reflector 42 and all of the emitted and reflected light is added to the direct beam emitted by the LEDs 22. The result obtained with the elements 21 placed in the luminaire 35 is absolutely unexpected and the light provided by the luminaire is sufficient to illuminate surfaces, such as facades, ceilings, etc. This fact was not obvious because the LED's light intensity is relatively low compared to that of conventional bulbs.

Des mesures ont été réalisées avec un luminaire « NEPTLTNE » tel que celui représenté en coupe dans la figure 7. Ce luminaire présente une longueur, largeur et hauteur de 0,875 m, respectivement 0,070 et 0,040. La longueur, respectivement largeur de la surface éclairante horizontale était de 0,835, respectivement 0,035 m. Ce luminaire contenait 15 éléments de deux fois 6 LED's pour une puissance de 18 Watts et d'un flux total en Lumen d'environ 1000.Measurements were made with a "NEPTLTNE" luminaire such as that shown in section in the figure 7 . This luminaire has a length, width and height of 0.875 m, 0.070 and 0.040 respectively. The length, respectively width of the horizontal illuminating surface was 0.835, respectively 0.035 m. This luminaire contained 15 elements of twice 6 LEDs for a power of 18 Watts and a total lumen flux of about 1000.

Comme déjà mentionné, les 6 LED's placées sur la partie supérieure de la platine de l'élément sont des LED's NICHIA 5 mm, diamètre 5,6 cd/20° et les 6 LED's placées sur la partie inférieure de la platine de l'élément sont des LED's NICHIA SMD 120°/60° 066 cd. Chaque élément est alimenté avec un courant de 24 V DC.As already mentioned, the 6 LEDs placed on the upper part of the element board are 5mm NICHIA LEDs, 5.6 cd / 20 ° diameter and the 6 LED's placed on the lower part of the element board. are LED's NICHIA SMD 120 ° / 60 ° 066 cd. Each element is powered with a current of 24 V DC.

La figure 8 est une représentation graphique présentant la répartition des intensités lumineuses 1 en diagramme polaire pour une direction selon l'axe du luminaire C90/C270 et une direction perpendiculaire à cet axe CO/C180.The figure 8 is a graphical representation showing the distribution of luminous intensities 1 in polar pattern for a direction along the axis of the luminaire C90 / C270 and a direction perpendicular to this axis CO / C180.

Comme déjà mentionné, les résultats obtenus avec l'élément d'éclairage qui vient d'être décrit sont excellents et le luminaire offre l'avantage d'une durée de vie extrêmement longue. Il peut être avantageusement utilisé dans un luminaire ou rail d'éclairage décrit dans le PCT/CH 97/00317 dans le but d'éclairer des surfaces importantes (façade, plafond, sol) avec un faisceau lumineux étroit et concentré sans perte de lumière.As already mentioned, the results obtained with the lighting element which has just been described are excellent and the luminaire offers the advantage of an extremely long service life. It can be advantageously used in a luminaire or lighting rail described in the PCT / CH 97/00317 in order to illuminate important surfaces (façade, ceiling, floor) with a narrow and concentrated light beam without loss of light.

Comme représenté dans les figures du dessin, le mode d'exécution et la variante de l'élément d'éclairage sont avantageusement utilisés dans un rail d'éclairage. L'élément d'éclairage 1 ou 21 sera donc dimensionné pour présenter une configuration allongée et être relativement mince. Toutefois, l'invention n'est pas limitée aux éléments décrits dans le dessin et l'élément d'éclairage peut présenter des changements importants. Dans le cas où l'on utilise un réflecteur, la platine 2 sera avantageusement munie de LED's sur 2 côtés. On peut bien évidemment prévoir une platine creuse ou de section triangulaire ou carrée. Dans ce cas, on obtient alors trois ou quatre rangées de LED's. On peut d'autre part, prévoir une platine beaucoup plus longue présentant des rangées avec un beaucoup plus grand nombre de LED's, sous une tension d'environ 4 volts par unité ou sous une autre tension en fonction des caractéristiques des LED's utilisées. Comme déjà mentionné plus haut, l'élément d'éclairage qui vient d'être décrit offre l'avantage d'une durée de vie très importante. Dans ces conditions, lorsqu'il est utilisé dans des rails ou rampes d'alimentation d'une grande longueur placées à des endroits peu accessibles, il offre un avantage très important dû à sa très longue durée de vie. D'autre part, il utilise moins de courant que des ampoules conventionnelles.As shown in the figures of the drawing, the embodiment and the variant of the lighting element are advantageously used in a lighting rail. The lighting element 1 or 21 will therefore be sized to have an elongated configuration and be relatively thin. However, the invention is not limited to the elements described in the drawing and the lighting element may have significant changes. In the case where a reflector is used, the plate 2 will advantageously be provided with LEDs on 2 sides. It is obviously possible to provide a hollow plate or triangular section or square. In this case, we then obtain three or four rows of LED's. On the other hand, we can provide a much longer platinum having rows with a much larger number of LEDs, under a voltage of about 4 volts per unit or other voltage depending on the characteristics of LEDs used. As already mentioned above, the lighting element which has just been described offers the advantage of a very long life. Under these conditions, when used in rails or ramps of great length placed in places not very accessible, it offers a very important advantage due to its very long life. On the other hand, it uses less current than conventional bulbs.
