Abstract

The invention concerns a light set with general power supply in series, and branch circuits in parallel. It consists of small bulbs (3) operating on very low voltage, mounted in parallel on flexible conductors (5, 5') with slight cross-section and with thin insulation forming branch circuits (4) connected in series on a cable (6) powered by the electric supply mains, such that the maximum voltage of each branch circuit is lower than the maximum safe voltage. The invention is useful for producing temporary or permanent light decorations, in particular outdoor decorations, such as those traditionally installed for festivities and other celebrations. It may also provide numerous applications, for instance in the field of advertising or for shop window displays, or in situations where safety standards are required.

Description

GUIRLANDE LUMINEUSE A ALIMENTATION ELECTRIQUE GENERALE EN SERIE ET DERIVATIONS EN PARALLELE.GARLAND LIGHT FEED ELECTRI Q EU GENERAL LEADS SERIES AND PARALLEL.
La présente invention a pour objet une guirlande lumineuse à alimentation électrique générale en série, et dérivations en parallèle.The present invention relates to a light garland with general electrical supply in series, and parallel branches.
Elle est destinée à la réalisation de décorations lumineuses temporaires ou permanentes, et en particulier de décorations situées à l'extérieur, telles que celles installées traditionnellement pour les fêtes ou autres manifestations . Elle peut cependant trouver de nombreuses applications, par exemple dans le domaine publicitaire ou pour l'animation de vitrines commerciales, ou lorsque des normes de sécurité doivent être observées .It is intended for the production of temporary or permanent light decorations, and in particular decorations located outside, such as those traditionally installed for parties or other events. It can however find many applications, for example in the advertising field or for the animation of commercial windows, or when security standards must be observed.
Il existe à ce jour un grand nombre de système de décors lumineux, surtout dans le domaine des installations temporaires réalisées aussi bien à l'extérieur qu'à l'intérieur lors des fêtes de fin d'année, par exemple.To date, there is a large number of lighting decoration systems, especially in the field of temporary installations carried out both outside and inside during the end of year celebrations, for example.
L'un de ces systèmes, qui rencontre un succès grandissant depuis quelques années, est constitué d'un nombe important d'ampoules électriques de faibles dimensions disposées à intervalles réguliers le longs de câbles d'alimentation et disposées en guirlandes ou en rideaux lumineux.One of these systems, which has met with increasing success in recent years, consists of a large number of small electric bulbs arranged at regular intervals along supply cables and arranged in garlands or light curtains.
Dans la plupart des cas, le dispositif est alimenté à partir de la tension du secteur (généralement 230 volts) par un câble principal 1 comportant des dérivations 2 branchées en parallèle et formées chacune d'une boucle sur laquelle les ampoules 3 sont montées en séries de façon à être alimentées individuellement en basse tension (figure 1).In most cases, the device is supplied from the mains voltage (generally 230 volts) by a main cable 1 comprising branches 2 connected in parallel and each formed of a loop on which the bulbs 3 are mounted in series so as to be supplied individually with low voltage (Figure 1).
Pour les installations à l'extérieur, les normes en vigueur imposent que les conducteurs non alimentés en très basse tension (inférieure à 48 volts) soient protégés par une gaine isolante en caoutchouc d'une certaine épaisseur. Dans le montage ci-dessus, les dérivations portant les ampoules sont branchées sur le câble principal et par conséquent les conducteurs formant ces dérivations, de même que le câble principal, reçoivent la tension du secteur et doivent comporter un isolant caoutchouc, ce qui n'est pas gênant pour le conducteur principal (forte section), mais rend les dérivations lourdes, difficiles a manipuler et peu esthétiques en raison du diamètre important des conducteurs.For outdoor installations, the standards in force require that conductors not supplied with very low voltage (less than 48 volts) be protected by an insulating rubber sheath of a certain thickness. In the above assembly, the branches carrying the bulbs are connected to the main cable and therefore the conductors forming these branches, as well as the main cable, receive the mains voltage and must include a rubber insulator, which is not annoying for the main conductor (large section), but makes the branches heavy, difficult to handle and unattractive due to the large diameter of the conductors.
En outre, lorsqu'une ampoule est déficiente et ne laisse plus passer le courant, la dérivation entière est hors d'usage.In addition, when a bulb is defective and no longer lets current flow, the entire bypass is out of order.
Le dispositif selon la présente invention a pour objectif de remédier à ces inconvénients. Il permet en effet de réaliser des décors utilisables à l'extérieur et constitués de guirlandes ou de rideaux d'ampoules miniatures montées le long de conducteurs électriques relativement fins, la déficience d'une ampoule ne provoquant pas l'extinction des autres ampoules branchées sur la même dérivation.The device according to the present invention aims to remedy these drawbacks. It makes it possible to produce decorations that can be used outside and consist of garlands or curtains of miniature bulbs mounted along relatively thin electrical conductors, the deficiency of a bulb not causing the extinction of other bulbs plugged into the same derivation.
Il est constitué de petites ampoules fonctionnant en très basse tension, montées en parallèle sur des conducteurs souples de faible section et à isolant mince formant des dérivations branchées en série sur un câble alimenté par le secteur de distribution électrique, de manière à ce que la tension de chaque dérivation soit inférieure à la tension maximale de sécurité.It consists of small bulbs operating at very low voltage, mounted in parallel on flexible conductors of small section and with thin insulation forming taps connected in series on a cable supplied by the electricity distribution sector, so that the voltage of each tap is less than the maximum safety voltage.
La description détaillée ci-après se rapporte à un exemple non limitatif d'une des formes de réalisation de l'objet de l'invention. Sur les dessins annexés : la figure 1, déjà citée, représente schématiquement un montage conforme aux installations existantes , la figure 2 montre dans les mêmes conditions le montage revendiqué par la présente demande de brevet et la figure 3 représente une portion de dérivation constituée de câbles torsadés. Le dispositif, figures 2 et 3, est constitué de plusieurs dérivations 4 constituées chacunes de deux conducteurs unifilaires 5 isolés et branchées en série sur une ligne d'alimentation 6 dont les extrémités sont branchées sur une source de tension 7 raccordée au secteu r .The detailed description below relates to a non-limiting example of one of the embodiments of the subject of the invention. In the appended drawings: FIG. 1, already cited, schematically represents an assembly in accordance with existing installations, FIG. 2 shows, under the same conditions, the assembly claimed by this patent application and FIG. 3 represents a branch portion made up of cables twisted. The device, Figures 2 and 3, consists of several branches 4 each consisting of two single-wire conductors 5 insulated and connected in series on a supply line 6, the ends of which are connected to a voltage source 7 connected to the sector.
Le long de chaque dérivation 4 sont montées des ampoules miniatures 3 fonctionnant en très basse tension, typiquement 6, 12 ou 24 volts, et branchées en parallèle entre les deux conducteurs unifilaires 5, 5'.Along each branch 4 are mounted miniature bulbs 3 operating at very low voltage, typically 6, 12 or 24 volts, and connected in parallel between the two single-wire conductors 5, 5 '.
Le nombre de dérivations devra être déterminé en fonction du voltage de l'alimentation générale et de la tension de fonctionnement des ampoules 3. Par exemple, ce nombre sera au moins égale à cinq pour une tension de secteur de 230 volts, afin que les dérivations 4 soient alimentées en très basse tension, c'est-à-dire inférieure à 48 volts, de manière à pouvoir utiliser des gaines isolantes minces et souples pour les conducteurs unifilaires 5.The number of taps must be determined according to the voltage of the general supply and the operating voltage of the bulbs 3. For example, this number will be at least five for a mains voltage of 230 volts, so that the taps 4 are supplied with very low voltage, that is to say less than 48 volts, so that thin and flexible insulating sheaths can be used for single-wire conductors 5.
Grâce à cette disposition, seule la ligne d'alimentation 6 devra comporter une gaine isolante en caoutchouc de forte épaisseur, les conducteurs 5, 5' des dérivations 4 pouvant être réalisés au moyen de conducteurs souples de faible section à isolant mince de type courant, par exemple en polychlorure de vinyle.Thanks to this arrangement, only the supply line 6 must have a thick rubber insulating sheath, the conductors 5, 5 ′ of the branches 4 being able to be produced by means of flexible conductors of small section with thin insulator of the current type, for example polyvinyl chloride.
Les dérivations 4 seront avantageusement constituées de câbles torsadés 7 (figure 3) ou méplats. Elles pourront comporter plus de deux conducteurs 5, de façon à former plusieurs circuits indépendants pouvant être équipés de lampes 3 de couleurs différentes.The branches 4 will advantageously consist of twisted cables 7 (Figure 3) or flats. They may include more than two conductors 5, to form several independent circuits that can be equipped with lamps ê 3 different colors.
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
