Abstract

The reflector is curved to fit closely round the outer edge of the front of an electric incandescent lamp (3). The illumination efficiency of the unit is enhanced by the close fitment of the reflector to the curve of the lamp. The lamp bulb (3) is held in place by punchings (4) on the inner surface of the reflector which are sufficiently flexible to allow the maximum diameter of the lamp bulb to be forced between them and to then retain the lamp bulb. The reflector (1) flares out from the lamp bulb in a curve (3) which retains the now precisely located lamp filament (F) at its focus. The flexibility of the reflector is obtained by punchings around the periphery, at the shoulder section enveloping the large diameter section.

Description

Les lampes réflecteurs sont d'un usage commode car elles peuvent être utilisées dans des appareils dépourvus de système optique, donc très simpli- fiés. Reflector lamps are convenient to use because they can be used in devices without an optical system, and therefore very simplified.

Ce type de lampe, très répandu, à l'inconvénient d'être ocuteux cn rempla cernent, car le réflecteur est perdu. Des systèmes connus de réflectcurs metal- liques clipsés sur l'ampoule d'une lampe à incandescence de forme stantard, ne permettent pas d'obtenir les performances des lampes réflecteurs en verre scellées, car l'ampoule sphérique est trop volumineuse pour définir une optique convenable, de dimensions et de performancescomparables à celles des lampes à miroir. D'autre part, ces réflecteurs sont généralement pourvus de clips ressorte rivetés, augmentant leur complexité et leur prix. This type of lamp, very widespread, has the disadvantage of being ocutaneous and replaces it because the reflector is lost. Known systems of metal reflectors clipped onto the bulb of a standard incandescent lamp do not allow the performance of sealed glass reflector lamps to be obtained, since the spherical bulb is too bulky to define an optic suitable, dimensions and performance comparable to that of mirror lamps. On the other hand, these reflectors are generally provided with riveted spring clips, increasing their complexity and their price.

La présente invention permet de remédier à ces inconvénients, grâce à l'utilisation d'une lampe, dont la forme d'ampoule (forme poire), permet, grâce au filament (foyer), plus proche du sommet de la courbe génératrice du réflecteur, dont le paramètre est de ce fait plus petit,/de conduire à une meilleu- re définition du système optique, ayant pour effet d'augmenter l'intensité du faisceau projeté.D'autre part, la forme enveloppante du réflecteur autour de la surface latérale de la lampe, permet de solidariser directement cette lampe avec le réflecteur, laquelle, selon l'invention, est rendue amovible, soit par olipsage direct, à l'aide de quelques poinçonnages réalisés en contre dépouille sur la partie épaulée du réflecteur enveloppant la périphérie de grand diamè- tre de l'ampoule, soit, maintenue par l'intermédiaire de la douille, laquelle est sertie dans l'embase cylindrique du réflecteur.  The present invention overcomes these drawbacks, thanks to the use of a lamp, the bulb shape (pear shape), allows, thanks to the filament (hearth), closer to the top of the generative curve of the reflector , whose parameter is therefore smaller, / leading to a better definition of the optical system, having the effect of increasing the intensity of the projected beam. On the other hand, the enveloping shape of the reflector around the lateral surface of the lamp, makes it possible to directly attach this lamp to the reflector, which, according to the invention, is made removable, either by direct olipage, using a few punchings made in undercut on the shoulder part of the enveloping reflector the large diameter periphery of the bulb, or, maintained by means of the socket, which is crimped in the cylindrical base of the reflector.

A titre indicatif, en se référant aux dessins annexés, une forme d'éxécu- tion de l'invention est décrite ci-après. By way of indication, with reference to the appended drawings, one embodiment of the invention is described below.

Le réflecteur est issu d'une tôle en aluminium emboutie ou repoussée sur un mandrin donnant sa forme qui est généralement une surface de révolution fig. I. La courbe génératrice curviligne peut se décomposée en 6 éléments qui correspondent aux différentes incurvations ou changements de pentes de la sur- faoe curviligne X
1 / une partie plate (a) perpendiculaire à l'axe focal x'x, délimitant l'orifice de passage de la partie arrière de la lampe, et suivant les cas, empochant le réflecteur de pénétrer à l'intérieur de la douille 2.The reflector comes from an aluminum sheet stamped or pushed on a mandrel giving its shape which is generally a surface of revolution fig. I. The curvilinear generating curve can be broken down into 6 elements which correspond to the different curvatures or changes in slopes of the curvilinear surface X
1 / a flat part (a) perpendicular to the focal axis x'x, delimiting the passage orifice of the rear part of the lamp, and depending on the case, pocketing the reflector to penetrate inside the socket 2 .

20/ une partie cylindrique (b) qui enveloppe la zone du queusot de la lampe 3,
30/ un élément réflecteur (c) épousant la forme latérale de l'ampoule,
40/ un épaulement (d) dont la distance par rapport à l'axe x'x correspond au grand diamètre de passage de l'ampoule. C'est sur cet élément que sont pratiqué les poinçonnages 4, destinés à clipser la lampe
50/ un élément réflecteur (e) correspondant à la surface active principale de configuration parabolique, elliptique etc..., dont le foyer F coincide avec le filaient de la lampe,
60/ le bord (f) du diamètre d'ouverture, se terminant par une collerette ou un rabat qui sert à augmenter la rigidité mécanique de la pièce et faciliter la mise en place du système dans l'appareil d'éclairage.20 / a cylindrical part (b) which envelops the zone of the lamp socket 3,
30 / a reflective element (c) matching the lateral shape of the bulb,
40 / a shoulder (d) whose distance from the axis x'x corresponds to the large diameter of passage of the bulb. It is on this element that are punched 4, intended to clip the lamp
50 / a reflective element (e) corresponding to the main active surface of parabolic, elliptical configuration, etc., whose focal point F coincides with the streak of the lamp,
60 / the edge (f) of the opening diameter, ending in a flange or a flap which serves to increase the mechanical rigidity of the part and facilitate the installation of the system in the lighting fixture.

Pour effectuer le ponçonnage sur (d), on doit tenir compte de la contre dépouille légère suivant l'are x'x, car si la tôle constituant le réflecteur est trop raide, il sera nécessaire d'effectuer une découpe sous forme de cimaillage d'une bande plus élastique dans le sens longitudinal ou transversal (fig. 2). Cette opération pourra 8tre effectuée en reprise sur un autre xan- drin comportant des saignées adéquates. To carry out sanding on (d), we must take into account the slight undercut along the area x'x, because if the sheet constituting the reflector is too stiff, it will be necessary to cut in the form of cimaillage d '' a more elastic band in the longitudinal or transverse direction (fig. 2). This operation can be carried out in recovery on another xandrin with adequate grooves.

La présente invention n'est pas limitée au mode de réalisation décrit et représenté, qui conetitue seulement un exemple auquel de nombreuses modifica- tions peuvent être apportées quant à la nature, à la forme et aux dimensions de ses éléments constitutifs, au mode de montage etc..., sans s'écarter de la présente invention. The present invention is not limited to the embodiment described and shown, which is only an example to which numerous modifications can be made as to the nature, the shape and the dimensions of its constituent elements, to the mounting method etc ..., without departing from the present invention.

L'invention peut être utilisée pour la réalisation de tous appareils d'éclairage architecturaux.  The invention can be used for the production of all architectural lighting fixtures.
