Abstract

L'invention concerne les systèmes lumineux (pour éclairage ou décoration) linéaires de faible encombrement. Elle se compose premièrement d'un support (figure 1) constitué d'un profil en "U" (1) dont chaque aile est garnie d'un profil compressible (2) supportant une lame de cuivre (3), les deux lames étant raccordées électriquement au secteur en bout de support, deuxièmement d'un alignement de modules encastrés dans le support, chaque module (figure 2) étant réalisé par enrobage (4) d'une série d'éléments lumineux (5) de petites dimensions affleurant ou partiellement découverts, série dont les bornes sont reliées électriquement à deux plaquettes de cuivre (6) affleurant chacune d'un côté du module. Le système conçu peut servir notamment à l'éclairage de tout endroit nécessitant un dispositif linéaire de faible encombrement (par exemple les meubles-vitrine domestiques). Pour obtenir un enrobage en une seule coulée ou injection qui laisse affleurer ou partiellement découverts les éléments lumineux, on utilise un moule dont deux parois en opposition sont garnies d'une couche compressible en élastomère ou en mousse recouverte d'un film plastique.The invention relates to linear lighting systems (for lighting or decoration) with small dimensions. It consists firstly of a support (Figure 1) consisting of a "U" profile (1) each wing of which is provided with a compressible profile (2) supporting a copper strip (3), the two strips being electrically connected to the mains at the end of the support, secondly from an alignment of modules embedded in the support, each module (FIG. 2) being produced by coating (4) with a series of light elements (5) of small dimensions flush or partially discovered, series whose terminals are electrically connected to two copper plates (6) each flush with one side of the module. The system designed can be used in particular for lighting any place requiring a linear device with a small footprint (for example household display cabinets). To obtain a coating in a single casting or injection which leaves the light elements flush or partially uncovered, a mold is used, two opposing walls of which are filled with a compressible layer of elastomer or foam covered with a plastic film.

Description

Système d'éclairare et de décoration lumineuse linéaire et de faible section, et procédé de réalisation Lighting system and linear light decoration and small section, and method of production
L'invention concerne les systèmes d'éclairage et de décoration lumineuse linéaire de faible section dont les sources lumineuses sont de petites lampes à incandescence.The invention relates to lighting systems and linear light decoration of small section whose light sources are small incandescent lamps.
On connaît des systèmes dans lesquels de telles lampes sont montées en parallèle sur un cordon d'alimentation, le tout étant inséré dans une gaine transparente ou un tube de verre. Ces systèmes présentent deux inconvénients. D'une part, ils ne peuvent fonctionner qu'en basse tension, d'où l'obligation d'utiliser un transformateur. D'autre part, le remplacement d'une lampe morte est incommode puisqu'il est nécessaire de dégager le circuit de la gaine ou du tube. On connaît aussi un système qui ne souffre pas du premier de ces inconvénients (brevet français ANQUETIN n° 2.351.352) puisque dans ce dernier, les lampes sont montées en séries directement aliraentables par le secteur, séries qui sont raccordées en parallèle à deux conducteurs, le tout étant inséré dans une gaine transparente. Par contre, le remplacement d'une lampe hors d'usage reste incommode dans ce système ; en effet, il faut repérer la lampe en question dans sa série,inciser la gaine à ce niveau, changer la lampe, reconstituer la série par soudage ou serrage de cosse et refermer la gaine par collage. Ces opérations nécessitent un mini mum de connaissances, d'outillage et de savoir-faire. L'auteur de la présente demande a décrit dans une demande de brevet française (FR 79 I948I) un système correspondant au préambule de la revendication I qui élimine les inconvénients des systèmes existants. Ce système d'éclairage et de décoration lumineuse consiste en un alignement de modules. Chacun est constitué d'une série de lampes, pouvant être alimentée directement par le secteur, raccordée en parallèle à deux conducteurs disposés dans l'axe de celle-ci, le tout étant enrobé d'une résine transparente ou translucide de telle sorte que les conducteurs affleurent aux extrémités du module selon une disposition qui permette l'encastrement de deux extrémités adjacentes dans une connexion qui assure le raccordement électrique. Ce système, ainsi que ceux cités précédemment, souffre d'un inconvénient, le confinement des lampes qui voient ainsi leur durée de vie raccourcie. Il souffre, avec ceux qui' utilisent une gaine, d'un deuxième inconvénient, une perte de flux luraineux lorsqu'on les utilise pour L'éclairage, de luminance lorsqu'on les utilise en décoration lumineuse. Enfin ce. système a un inconvé nient spécifique ; lorsqu'on remplace un module hors d'usage, on remplace aussi les conducteurs d'alimentation, ce qui constitue un gaspillage.Systems are known in which such lamps are mounted in parallel on a power cord, the whole being inserted in a transparent sheath or a glass tube. These systems have two drawbacks. On the one hand, they can only operate at low voltage, hence the obligation to use a transformer. On the other hand, replacing a dead lamp is inconvenient since it is necessary to clear the circuit from the sheath or tube. A system is also known which does not suffer from the first of these drawbacks (French patent ANQUETIN No. 2,351,352) since in the latter, the lamps are mounted in series directly adjustable by the sector, series which are connected in parallel to two conductors , the whole being inserted in a transparent sheath. On the other hand, the replacement of a lamp out of use remains inconvenient in this system; Indeed, it is necessary to locate the lamp in question in its series, to incise the sheath at this level, to change the lamp, to reconstitute the series by welding or tightening of the terminal and to close the sheath by gluing. These operations require a minimum amount of knowledge, tools and know-how. The author of the present application has described in a French patent application (FR 79 I948I) a system corresponding to the preamble of claim I which eliminates the drawbacks of the existing systems. This lighting and light decoration system consists of an alignment of modules. Each consists of a series of lamps, which can be supplied directly from the mains, connected in parallel to two conductors arranged in the axis thereof, the whole being coated with a transparent or translucent resin so that the conductors are flush with the ends of the module in an arrangement which allows the embedding of two adjacent ends in a connection which provides the electrical connection. This system, as well as those mentioned above, suffers from a drawback, the confinement of the lamps which thus see their life shortened. It suffers, with those who 'use a sheath, a second drawback, a loss of luraine flow when used for lighting, luminance when used in lighting decoration. Finally this. system has a drawback deny specific; when you replace an out-of-use module, you also replace the supply conductors, which is a waste.
La présente invention telle qu'elle est caractérisée dans les revendications vise à éliminer ces inconvénients. On a repris ici le principe des modules. Chacun est constitué d'une série de lampes, la tension d'alimentation de celle-ci est celle du secteur. Chaque borne de la série est reliée à un élément de contact, plaquette ou broche de cuivre. Le tout est enrobé d'une résine transparente (translucide pour obtenir certains effets luιsineux)de telle sorte que les éléments de contact affleurent ou émergent du bloc qui constitue l'enrobage et que les lampes affleurent oμ soient partiellement découvertes. Le bloc d'enrobage a la forme d'un parallèlébipède rectangle. Les modules sont insérés "en force" dans un support en "U", rectiligne ou non, qui contient deux conducteurs, dénudés au moins au niveau des éléments de contact des modules, reliés au secteur à l'extrémité du support. Différents cas .de figure sont à envisager. Si on utilise des plaquettes affleurant de part et d'autre du module, le support en "U" aura ses conducteurs disposés sur la face interne de chaque aile. Dans ce cas, si la résine d'enrobage est rigide après polymérisation, les conducteurs seront disposés sur un profilé en élastomère ou en mousse (c'est donc la compressibilité de ces profilés qui assurera le maintien en place des modules et la qualité du contact électrique) ; si la résine d'enrobage est compressible après polymérisation (élastomère), les conducteurs seront disposés directement sur la face interne des ailes du support qui sera profilée de manière adéquate pour recevoir le conducteur (dans ce cas, c'est la compressibilité de la résine d'enrobage qui assure le maintien en place des modules et la qualité du contact électrique). Si on utilise des broches émergeant sous le bloc d'enrobage, les conducteurs seront disposés au fond du support noyés dans un profilé d' élastomère ; celui-ci comportera deux fentes longitudinales sur toute la longueur du support, à l'aplomb des conducteurs, afin de permettre le passage des broches de contact (dans ce cas, les broches qui entrent "en force" dans les fentes du profilé d'élastomère qui contient les conducteurs et c'est la pression sur ces broches qui maintient le module en place). Ce système comporte plusieurs avantages par rapport aux systèmes existants. Il fonctionne sans transformateur puisque chaque série de lampes peut recevoir le courant du secteur. Le remplacement d'un module hors- sçrvice ne nécessite aucune connaissance technique, aucun outillage, aucun savoir-faire ; il est aussi simple que celui d'une lampe à incandescence standard dans un luminaire domestique. Les lampes étant partie lement découvertes, il n'y a plus confinement et la perte de flux lumi neux ou de luminance est presque inexistante. On ne remplace que la par tie "lampes". Enfin lorsqu'on utilise le système pour la décoration lumineuse, par exemple en réalisant des panneaux lumineux en disposant côte à côte un certain nombre de supports, un avantage existe sur les systèmes existants : l'utilisateur peut réaliser lui-même la composi tion qu'il désire en jouant sur l'écartement entre les modules ou sur les couleurs (cas où les modules sont réalisés avec des lampes colorées) et il peut à tout moment changer cette composition.The present invention as characterized in the claims aims to eliminate these drawbacks. We have used the principle of modules here. Each consists of a series of lamps, the supply voltage of which is that of the sector. Each terminal in the series is connected to a contact element, plate or copper pin. The whole is coated with a transparent resin (translucent to obtain certain luιsinous effects) so that the contact elements are flush or emerge from the block which constitutes the coating and that the lamps are flush where they are partially uncovered. The coating block has the shape of a rectangular parallelepiped. The modules are inserted "by force" into a "U" support, straight or not, which contains two conductors, stripped at least at the contact elements of the modules, connected to the sector at the end of the support. Different cases .de figure are to be considered. If you use plates flush with each other on the module, the U-shaped support will have its conductors arranged on the internal face of each wing. In this case, if the coating resin is rigid after polymerization, the conductors will be arranged on an elastomer or foam profile (it is therefore the compressibility of these profiles which will ensure that the modules are held in place and the quality of the contact electric); if the coating resin is compressible after polymerization (elastomer), the conductors will be placed directly on the internal face of the wings of the support which will be adequately profiled to receive the conductor (in this case, it is the compressibility of the resin coating which keeps the modules in place and the quality of the electrical contact). If pins emerging under the coating block are used, the conductors will be arranged at the bottom of the support embedded in an elastomer profile; this will include two longitudinal slots along the entire length of the support, plumb with the conductors, in order to allow the passage of the contact pins (in this case, the pins which enter "forcefully" into the slots of the profile elastomer which contains the conductors and it is the pressure on these pins which keeps the module in place). This system has several advantages over existing systems. It works without transformer since each series of lamps can receive the current of the sector. The replacement of an off-module sçrvice requires no technical knowledge, no tools, no know-how; it's as simple as that of a standard incandescent lamp in a home fixture. As the lamps have been partially discovered, there is no longer any confinement and the loss of light flux or luminance is almost nonexistent. We only replace the "lamps" part. Finally, when the system is used for light decoration, for example by producing light panels by placing a certain number of supports side by side, an advantage exists over existing systems: the user can carry out the composition himself. '' he wishes by playing on the spacing between the modules or on the colors (case where the modules are made with colored lamps) and he can change this composition at any time.
Une réalisation du systèiae décrit (figures I, 2 et 3) a consisté à enrober dix petites la-spes (i) à incandescence de 24 volts de tensi unitaire ("luciol" de MAZDA), reliées en série, les bornes de la série ayant été soudées à deux petites plaquettes de cuivre (2). Le tout a été enrobé dans une résine époxy (3) transparente incolore ("In Epox" vendue par la société ADAM) de telle sorte que les deux plaquettes de cuivre affleurent et que les lampes soient partiellement découvertes. Le support (figure 3) a été réalisé en moulant deux profils (4) en élas tomère de silicone ("RTV 589" de RHONE POULENC) sur lesquels a été collée une lame de cuivre (5) de 0,5 X 2 mm de section, raccordée chacune au secteur à l'extrémité du support, chaque profil ayant été collé sur une des ailes d'un profil d'aluminium (6) en "U". La réalisation d'un module pose le problème du moule. En effet, pour obtenir qu'après démoulage les éléments lumineux affleurent ou soient partiellement découverts, tout en préservant la possibilité de réaliser l'enrobage en une seule coulée ou injection, il est nécessaire d'aménager le moule de façon particulière. Le système de moulage-enrobage conçu consiste à placer sur deux faces internes du moule en opposition une garniture en élastomère ou en mousse recouverte d'un film plastique permettant un démoulage aisé, c'est-à-dire d'avoir dans le moule deux faces en opposition compressibles. On peut positionner les éléments lumineux dans le moule en les descendant "en force", le raccordement électrique entre ceux-ci ayant été fait avant.An embodiment of the system described (FIGS. I, 2 and 3) consisted in coating ten small la-spes (i) with incandescent 24 volts of unit tensi ("luciol" from MAZDA), connected in series, the terminals of the series having been soldered to two small copper plates (2). The whole was coated in a colorless transparent epoxy resin (3) ("In Epox" sold by the company ADAM) so that the two copper plates are flush and the lamps are partially uncovered. The support (Figure 3) was made by molding two profiles (4) in silicone elas tomera ("RTV 589" from RHONE POULENC) on which was glued a copper strip (5) of 0.5 X 2 mm section, each connected to the sector at the end of the support, each profile having been glued to one of the wings of an aluminum profile (6) in a "U" shape. The realization of a module poses the problem of the mold. Indeed, to obtain that after demolding the light elements are flush or are partially uncovered, while preserving the possibility of carrying out the coating in a single casting or injection, it is necessary to arrange the mold in a particular way. The molding-coating system designed consists of placing on two internal faces of the mold in opposition an elastomer or foam lining covered with a plastic film allowing easy demolding, that is to say having in the mold two compressible opposing faces. The light elements can be positioned in the mold by lowering them "in force", the electrical connection between them having been made before.
Une réalisation du système (figures 4 et 5) a consisté en un moule parallèlébipédique rectangle ouvert en trois parties J un fond (l) en métal inséré entre deux faces constituées chacune d'un méplat métallique (2) sur lequel a été collée une bande de mousse adhéoive (3) recouverte d'un film adhésif de polytétrafluoréthylène (vendu par "3M") (4); deux bouchons en élastomère de silicone (5) étaient disposés aux extrémités et le tout était suffisamment compressé par des serre-joints pour assurer 1 'étanchéïté. La coulée s'effectuait par gravité après positionnement de la série de lampes (6) et des plaquettes de cuivre (7) servant de bornes. Pour le positionnement dans le moule, les plaquettes étaient collées à deux petits plots (8) de même résine que celle utilisée pour l'enrobage. An embodiment of the system (Figures 4 and 5) consisted of a rectangular parallelepiped mold open in three parts J a bottom (l) of metal inserted between two faces each consisting of a metal flat (2) on which has been stuck a strip of adhesive foam (3) covered with an adhesive film of polytetrafluoroethylene (sold by "3M") (4); two silicone elastomer plugs (5) were placed at the ends and the whole was sufficiently compressed by clamps to ensure the seal. The casting was carried out by gravity after positioning the series of lamps (6) and copper plates (7) serving as terminals. For positioning in the mold, the plates were glued to two small studs (8) of the same resin as that used for the coating.
