Description
La présente invention concerne les lampes d'éclairage à faisceau dirigé, dans lesquels la source lumineuse à incandescence est solidaire du réflecteur, de manière à former un ensemble optique compact facile à placer dans les luminaires. The present invention relates to directional beam lighting lamps, in which the incandescent light source is integral with the reflector, so as to form a compact optical assembly which is easy to place in luminaires.
Les procédés connus, de ce genre, consistent à effectuer un sertissage mécanique de l'embase du réflecteur sur la source, or, certains modèles de sources ne permettent pas, ou difficilement, l'utilisation d'un tel procédé. Known methods of this kind consist in carrying out a mechanical crimping of the base of the reflector on the source, but certain models of sources do not allow, or are difficult, the use of such a method.
La présente invention, permet de remédier à ces inconvénients, par l'utilisation d'un ciment réfractaire (céramique), inséré d'une part, entre ltembase du réflecteur (côté intérieur) et la source, et d'autre parts entre ltembase du réflecteur (coté extérieur), puis le prolongement de la source et une bague ou manchon rapporté, coiffant les deux pièces. Ce procédé ne nécessite aucun outillage spécial de positionnement et de montage. The present invention overcomes these drawbacks by using a refractory cement (ceramic), inserted on the one hand between the base of the reflector (interior side) and the source, and on the other hand between the base of the reflector (exterior side), then the extension of the source and an attached ring or sleeve, covering the two parts. This process does not require any special positioning and mounting tools.
Une forme d'exécution de l'invention est décrite ci-après, à titre indicatif en se référant au dessin annexé. An embodiment of the invention is described below, by way of indication with reference to the attached drawing.
La lampe à sceller dans le réflecteur i, se compose de ltampoule en quarts 2 cylindrique, renfermant le filament et l'halogène, puis se prolonge jusqu'à la base (queusot) dont une partie est noyeé dans un support en céramique 4, recevant le culot métallique 5. The lamp to be sealed in the reflector i, consists of the cylindrical quarter bulb 2, containing the filament and the halogen, then extends to the base (queusot), part of which is embedded in a ceramic support 4, receiving the metal base 5.
On opère le scellement en enduisant ltembase de l'ampoule avec de la colle réfractaire à base de silice SI02, puis on introduit la lampe dans l'embase cylindrique 3 du réflecteur, laquelle vient en butée sur le support de céramique 4, dont le diamètre extérieur est sensiblement identique à celui de l'embase du réflecteur. On enduit ensuite les deux surfaces extérieures de 3 et 4 que lton coiffe par un manchon 6, en forme d'anneau cannelé en aluminium. Le manchon 6 étant métallique, il faut veiller à laisser une distance suffisante d'isolation avec le culot. Pour éviter tout descellement accidentel et glissement de la bague métallique vers l'arrière, on pratique un ou deux bourrelets 7 de colle sur le champ extérieur, entre l'anneau et l'embase céramique. The sealing is carried out by coating the base of the bulb with refractory glue based on silica SI02, then the lamp is introduced into the cylindrical base 3 of the reflector, which abuts on the ceramic support 4, the diameter of which exterior is substantially identical to that of the base of the reflector. The two outer surfaces are then coated with 3 and 4 which are covered by a sleeve 6, in the form of a grooved aluminum ring. The sleeve 6 being metallic, care must be taken to leave a sufficient distance of insulation with the base. To avoid any accidental loosening and sliding of the metal ring backwards, one or two beads 7 of glue are practiced on the external field, between the ring and the ceramic base.
La présente invention ntest pas limité au mode de réalisation décrit et représenté, qui constitue un exemple auquel de nombreuses modifications peuvent être apportées sans s'écarter de la présente invention. The present invention is not limited to the embodiment described and shown, which constitutes an example to which numerous modifications can be made without departing from the present invention.
