Abstract
Description
La présente invention concerne des anneaux lumineux pour équipements automobiles, constitués d'une partie en matière plastique conductrice de lumière comprenant pour l'essentiel : un nanchon, une collerette annulaire avant et un support pour une source lumineuse, dans laquelle les rayons lumineux émis par la source sont transmis à la collerette annulaire à travers le manchon pour former un cercle lumineux autour de l'équipement. The present invention relates to light rings for automotive equipment, consisting of a part of light-conducting plastic material essentially comprising: a nanchon, a front annular collar and a support for a light source, in which the light rays emitted by the source are transmitted to the annular collar through the sleeve to form a luminous circle around the equipment.
Des anneaux du type indiqué ci-dessus sont fréquemment utilisés dans des allume-cigares électriques constitués par un embout amovible. Lorsqu'il est monté sur un tableau de bord ou sur tout autre panneau, le support de la source lumineuse est normalement disposé sur le manchon. Etant donné que la lumière est transmise directement à travers le manchon, la collerette annulaire avant est davantage illuminée en haut et mcins bien entas. Rings of the type indicated above are frequently used in electric cigarette lighter devices constituted by a removable tip. When mounted on a dashboard or any other panel, the light source support is normally placed on the sleeve. Since the light is transmitted directly through the sleeve, the front annular flange is more illuminated at the top and much less.
L'une des solutions proposées pour remédier à cet inconvénient et obtenir une meilleure répartition de la lumière sur toute la circonférence de la collerette est décrite dans le brevet italien nO 874.086. Dans ce document, il est proposé de prévoir une collerette annulaire possédant, sur sa surface arrière, un agencement en forme de rayons de dièdres qui font fonction de prismes pour répartir la lumière. Cette solution résout partiellement l'inconvénient, mais ne le supprime pas totalement, car on ne peut pas dire que la répartition lumineuse ainsi obtenue est parfaitement uniforme. One of the solutions proposed to remedy this drawback and obtain a better distribution of light over the entire circumference of the flange is described in Italian patent No. 874.086. In this document, it is proposed to provide an annular flange having, on its rear surface, an arrangement in the form of dihedral rays which function as prisms for distributing the light. This solution partially solves the drawback, but does not completely eliminate it, because it cannot be said that the light distribution thus obtained is perfectly uniform.
La présente invention a pour but de remédier aux inconvénients indiqués ci-dessus, en assurant une répartition lumineuse- uniforme sur tout le périmètre de la collerette annulaire. The present invention aims to remedy the drawbacks indicated above, by ensuring a uniform light-distribution over the entire perimeter of the annular flange.
Conformément à la présente invention, ce but est atteint au moyen d'un anneau lumineux du type indiqué précédemment, caractérisé en ce que l'extrémité du manchon opposa à la collerette est découpée en oblique par rapport à l'axe du manchon proprement dit, de manière à former des surfaces spiralées qui s'étendent du voisinage du support de la source lumineuse, vers la collerette et vers la partie du manchon diamétralement opposée au support. In accordance with the present invention, this object is achieved by means of a light ring of the type indicated above, characterized in that the end of the sleeve opposite the flange is cut obliquely relative to the axis of the sleeve itself, so as to form spiral surfaces which extend from the vicinity of the support of the light source, towards the collar and towards the part of the sleeve diametrically opposite to the support.
Cette solution permet d'obtenir facilement une répartition effectivement uniforme de la lumière le long du périmètre de la col leratte annulaire, en utilisant une seule pièce en matière plastique moulée à moindre court. This solution makes it possible to easily obtain an effectively uniform distribution of the light along the perimeter of the annular collar, using a single piece of molded plastic material at shortest.
Les différents objets et caractéristiques de l'invention seront maintenant détaillés dans la description qui va suivre, faite à titre d'exemple non limitatif, en se reportant aux figures annexées qui représentent :
- la figure 1, une vue en perspective d'un anneau lumineux conforme à l'invention,
- la figure 2, une vue de côté de l'anneau représenté à la figure 1,
- la figure 3, une vue en coupe selon l'axe III-III de la figure 2.The various objects and characteristics of the invention will now be detailed in the description which follows, given by way of nonlimiting example, with reference to the appended figures which represent:
FIG. 1, a perspective view of a light ring according to the invention,
FIG. 2, a side view of the ring shown in FIG. 1,
- Figure 3, a sectional view along the axis III-III of Figure 2.
En référence aux figures, le chiffre de référence 1 désigne, dans son intégralité, un anneau lumineux destiné à entourer un équi- pement de véhicule, par exemple un allume-cigares électrique. Un anneau de ce type peut également être utilisé, à l'intérieur d'un véhicule, par exemple dans un bloc d'éclairage. With reference to the figures, the reference numeral 1 designates, in its entirety, a luminous ring intended to surround a vehicle equipment, for example an electric cigar lighter. A ring of this type can also be used, inside a vehicle, for example in a lighting unit.
L'anneau est constitué d'une pièce en matière plastique conductrice de la lumière comme, par exemple, un polycarbonate du type commercialisé sour la marque Makrolon'. The ring consists of a piece of light-conducting plastic, such as, for example, a polycarbonate of the type sold under the brand Makrolon '.
L'anneau 1 comprend pour l'essentiel un manchon 2, constitué d'une portion cylindrique, une collerette annulaire avant 3 et un support tubulaire 4 destiné à une source lumineuse représentée sché- matiquement et désignée par S. The ring 1 essentially comprises a sleeve 2, consisting of a cylindrical portion, an annular front flange 3 and a tubular support 4 intended for a light source represented schematically and designated by S.
L'anneau 1 est fixé de maniera connue au panneau d'un tableau de bord de véhicule au moyen d'une paire de dents élastiques encliquetables 5 moulées sur et sous le manchon 2, en des points dia métralement opposés. The ring 1 is fixed in a known manner to the panel of a vehicle dashboard by means of a pair of snap-on elastic teeth 5 molded on and under the sleeve 2, at dia metrically opposite points.
L'extrémité du manchon 2 opposa à la collerette annulaire 3 est découpée en oblique par rapport à l'axe A du manchon 2 proprement dit, de manière à former des surfaces spiralées 6 qui s'étendent du voisinage du support 4 de la source lumineuse , vers la collerette 3 et vers la partie du manchon 2 diamétralement opposa au support 4. The end of the sleeve 2 opposite the annular flange 3 is cut obliquely with respect to the axis A of the sleeve 2 proper, so as to form spiral surfaces 6 which extend from the vicinity of the support 4 of the light source , towards the collar 3 and towards the part of the sleeve 2 diametrically opposite the support 4.
Le siège 4 est flanqué d'une paire de saillies 7 moulées sur le manchon 2. The seat 4 is flanked by a pair of projections 7 molded on the sleeve 2.
Le rôle de cette paire de saillies 7 et des surfaces spira lées 6 est de réfléchir les rayons lumineux émis par la source S disposée à l'intérieur du support 4, de manière à les transmettre, à travers le manchon 2, jusqu'a la collerette annulaire 3 qui est ainsi uniformément illuminée, un cercle lumineux étant formé autour de l'équipement. The role of this pair of protrusions 7 and the spiraled surfaces 6 is to reflect the light rays emitted by the source S disposed inside the support 4, so as to transmit them, through the sleeve 2, up to the annular collar 3 which is thus uniformly illuminated, a luminous circle being formed around the equipment.
En particulier, les saillies 7 qui flanquent le support tubulaire 4 possèdent des surfaces extérieures respectives courbes 7a sur lesquelles sont réfléchis les rayons provenant de la source lumineuse : les saillies 7 font ainsi fonction de prismes qui reflètent les rayons émis latéralement par la source et les dévient sur les surfaces spiralées 6. En étant ensuite refléchis sur les surfaces spiralées 6, les rayons lumineux sont déviés et répartis uniformément sur le périmètre de la collerette annulaire 3, comme indiqué aux figures 2 et 3 où les rayons sont désignés par R. In particular, the projections 7 which flank the tubular support 4 have respective curved outer surfaces 7a on which the rays coming from the light source are reflected: the projections 7 thus act as prisms which reflect the rays emitted laterally by the source and the deflects on the spiral surfaces 6. Then being reflected on the spiral surfaces 6, the light rays are deflected and distributed uniformly around the perimeter of the annular flange 3, as indicated in FIGS. 2 and 3 where the rays are designated by R.
I1 est bien entendu que la présente invention s'applique à des modes de réalisation qui permettent d'obtenir les mêmes avantages à l'aide du même principe que celui exposé dans le cadre de la présente invention. It is understood that the present invention applies to embodiments which make it possible to obtain the same advantages using the same principle as that set out in the context of the present invention.
