Abstract
Description
La présente invention concerne la réutilisation des lampes à incandescence une fois grillées (hors d'usage).lors- qu une lampe à incandescence est grillée, phénomène causé dans la plupart des cas par la rupture du filament interne à l'ampoule, celle-ci ne fonctionnant plus est à jeter. The present invention relates to the reuse of incandescent lamps once burnt out (out of order) .when an incandescent lamp is burnt out, phenomenon caused in most cases by the rupture of the filament internal to the bulb, this- it no longer works is to be thrown away.
Le dispositif selon l'invention permet de remédier à cet inconvénient et permet à l'ampoule de pouvoir être réutiliser, en multipliant le nombre de filaments.Il comporte en effet selon une première caractéristique une ampoule ayant deux filaments en parallèle ou en perpendiculaire ne se touchant pas.Ces filaments possèdent une même entrée de courant mais des sorties différentes.Dans le cas des ampoules à bannette, le culot est équipé de deux points de contact, pour faire circuler le courant électrique, nous y ajoutons un troisième.Nous conservons un ancien point de contact comme entrée commune de courant, les deux autres points de contact serviront comme sortie de courant pour chaque filament.Nous couvrons un ancien point de contact utilisé comme sortie de courant avec un capuchon fait en matière isolant, on y colle dessus une matière conductrice branché au troisième point de contact (ce point est la deuxième sortie de courant) ainsi le dispositif fonctionne comme une ampoule ayant un filament traverser par le courant électrique et un culot avec ses deux points de contact classique. The device according to the invention overcomes this drawback and allows the bulb to be able to be reused, by multiplying the number of filaments. In fact, according to a first characteristic, a bulb having two filaments in parallel or perpendicular does not These filaments have the same current input but different outputs. In the case of baffle bulbs, the base is equipped with two contact points, to circulate the electric current, we add a third. We keep a old contact point as common current input, the two other contact points will serve as current output for each filament. We cover an old contact point used as current output with a cap made of insulating material, we stick on it a conductive material connected to the third contact point (this point is the second current output) so the device works co even a bulb having a filament through which the electric current passes and a base with its two conventional contact points.
Une fois le filament grillé (rompu), il suffit de retirer le capuchon pour pouvoir utiliser le point de contact sortie de courant qui alimente le deuxième filament; en procédant ainsi nous venons de réutiliser l'ampoule.Once the filament is burnt out (broken), it is enough to remove the cap to be able to use the contact point current output which feeds the second filament; by doing so we have just reused the bulb.
Les dessins annexés illustrent l'invention :
La figure 1 représente une vue de dessus de l'ampoule.The accompanying drawings illustrate the invention:
Figure 1 shows a top view of the bulb.
La figure 2 représente une vue en coupe transversale de l'ampoule. Figure 2 shows a cross-sectional view of the bulb.
La figure 3 représente une vue détaillée du capuchon qui recouvre le point de contact.FIG. 3 represents a detailed view of the cap which covers the contact point.
En référence à ces dessins, le dispositif comporte une ampoule (1) équipée de deux filaments (2) et (3) reliés à une entrée de courant par le contact (4) et deux sorties de courant (5) et (6) avec un capuchon (7) venant recouvrir le contact (5).Ce capuchon est composé d'une matière isolante (8) et d'une conductrice (9). With reference to these drawings, the device comprises a bulb (1) equipped with two filaments (2) and (3) connected to a current input by the contact (4) and two current outputs (5) and (6) with a cap (7) covering the contact (5). This cap is composed of an insulating material (8) and a conductor (9).
Bien entendu l'invention ntest pas limitée aux modes de réalisations décrits et représentés pour lesquels on pourra prévoir des variantes en particulier dans - les matières composant le dispositif. Of course, the invention is not limited to the embodiments described and shown for which it is possible to provide variants in particular in - the materials making up the device.
- la forme des ampoules.- the shape of the bulbs.
- le mode de fixation des ampoules sur les douilles (ballon nette, vissage ou autre).- the method of fixing the bulbs to the sockets (clean balloon, screwing or other).
- le nombre de filaments.- the number of filaments.
sans pour cela sortir du cadre de l'invention. without departing from the scope of the invention.
