According to other characteristics of the invention - the plate is secured to an axis mounted to rotate freely on a support inside the housing and comprising, at its free end situated outside said housing, a control of the rotation of this plate, - the control member is formed by a wheel, - the plate is associated with indexing means for the positioning of an element for modifying the light beam opposite the reflector of said light source, - the indexing means are formed by notches formed on the peripheral edge of the plate and cooperating with a ball displaceable in translation under the spring action in the direction of said plate, - the elements for modifying the light beam are formed by lenses.

L'invention également pour objet un plafonnier d'éclairage d'un habitacle de véhicule automobile, caractérisé en ce qu'il comporte un dispositif d'éclairage tel que précédemment mentionné. The invention also relates to a ceiling light for the interior of a motor vehicle, characterized in that it comprises a lighting device as previously mentioned.

Les caractéristiques et avantages de l'invention apparaîtront au cours de la description va suivre, donnée à titre d'exemple et faite en réfé rence aux dessins annexes, sur lesquels - la Fig. est une vue schématique en coupe transversale d'un plafonnier de véhicule automobile équipé d'un dispositif d'éclairage conforme à l'invention, - la Fig. 2 est une vue en coupe selon la ligne 2-2 de la Fig. 1. Sur la 1, on a représenté schématiquement un plafonnier désigné dans son ensemble par la référence 1, muni d'un dispositif d'éclairage conforme à l'invention destiné à éclairer l'habitacle d'un véhicule automobile. The characteristics and advantages of the invention will appear during the description which follows, given by way of example and made with reference to the accompanying drawings, in which - FIG. is a schematic cross-sectional view of a motor vehicle dome fitted with a lighting device according to the invention, - FIG. 2 is a sectional view along line 2-2 of FIG. 1. On 1, there is shown schematically a ceiling lamp designated as a whole by the reference 1, provided with a lighting device according to the invention intended to illuminate the passenger compartment of a motor vehicle.

Ce dispositif d'éclairage comporte un boîtier 2 fixé sur une sur face de support constituée, dans l'exemple de réalisation représenté sur les figu res, par une garniture 3 pavillon 4. This lighting device comprises a box 2 fixed on a support face formed, in the embodiment shown in the figures, by a lining 3 pavilion 4.

Le dispositif comporte également un support 5 fixé à l'intérieur du boîtier 2 par exemple moyen d'organes de vissage 6 et qui comporte une source lumineuse 7 associée à un réflecteur 8. The device also comprises a support 5 fixed inside the housing 2, for example by means of screwing members 6 and which comprises a light source 7 associated with a reflector 8.

Ce réflecteur 8 est disposé derrière la source lumineuse 7 et a pour but de diriger le faisceau lumineux 10 émis par ladite source lumineuse 7 vers la face frontale du boîtier 2 qui comporte, dans l'axe de cette source lumi neuse 7, une zone 2a réalisée en un matériau transparent. This reflector 8 is disposed behind the light source 7 and aims to direct the light beam 10 emitted by said light source 7 towards the front face of the housing 2 which comprises, in the axis of this light source 7, a zone 2a made of a transparent material.

La source lumineuse 7 disposée sur le support 5 est donc fixe. dispositif d'éclairage comporte aussi un plateau 15 muni à sa périphérique d'éléments 16 de modification du faisceau lumineux 10 émis par la source 7 et déplaçable en rotation pour amener un desdits éléments 16 en re gard du réflecteur 8 de ladite source lumineuse 7 en fonction du type de faisceau 10 à obtenir. The light source 7 disposed on the support 5 is therefore fixed. lighting device also comprises a plate 15 provided at its peripheral with elements 16 for modifying the light beam 10 emitted by the source 7 and movable in rotation to bring one of said elements 16 to the reflector 8 of said light source 7 in depending on the type of beam 10 to obtain.

Pour cela, le plateau 15 est solidaire d'un axe 17 monté libre en rotation sur le support 5 à l'intérieur du boîtier 2. For this, the plate 15 is secured to an axis 17 mounted free in rotation on the support 5 inside the housing 2.

axe 17 comporte, à son extrémité libre 17a située à l'exté rieur du boîtier un organe de commande de la rotation du plateau 15 qui, dans l'exemple de réalisation représenté à la Fig. 1, est constitué par une molette 18. axis 17 comprises, at its free end 17a situated outside the housing, a member for controlling the rotation of the plate 15 which, in the embodiment shown in FIG. 1, is constituted by a wheel 18.

Les éléments de modification du faisceau lumineux 10 émis par la source 7 sont constitués par des lentilles 16 réparties sur le plateau 15, comme représenté à la Fig. 2, et qui ont chacune des caractéristiques différentes déter minées en fonction du faisceau lumineux 10 à obtenir. The elements for modifying the light beam 10 emitted by the source 7 are constituted by lenses 16 distributed on the plate 15, as shown in FIG. 2, and which each have different characteristics determined as a function of the light beam 10 to be obtained.

Par exemple, l'une des lentilles permet de former un faisceau étroit, une autre un faisceau beaucoup plus large pour un éclairage général de l'habitacle ou encore l'une des lentilles permet d'orienter le faisceau lumineux vers la console centrale et une autre vers le passager pour la lecture d'une carte routière. For example, one of the lenses makes it possible to form a narrow beam, another a much wider beam for general lighting of the passenger compartment or even one of the lenses makes it possible to direct the light beam towards the central console and a another to the passenger for reading a road map.

Selon une autre variante, les lentilles peuvent modifier la couleur du faisceau lumineux de façon à donner un éclairage particulier à l'habitacle du véhicule automobile. According to another variant, the lenses can modify the color of the light beam so as to give particular lighting to the passenger compartment of the motor vehicle.

Ainsi, l'utilisateur peut, à l'aide de la molette 18, modifier le fais ceau lumineux 10 émis par la source 7 en positionnant l'une des lentilles 1 en regard du réflecteur 8 de la source lumineuse 7 en fonction de l'éclairage 'il souhaite obtenir. Thus, the user can, using the wheel 18, modify the light beam 10 emitted by the source 7 by positioning one of the lenses 1 opposite the reflector 8 of the light source 7 as a function of the lighting 'he wishes to obtain.

Afin de focaliser la lentille 16 en face du réflecteur 8, le plateau 15 est associé à des moyens d'indexation pour le positionnement de la lentille 16 sélectionnée. In order to focus the lens 16 in front of the reflector 8, the plate 15 is associated with indexing means for positioning the lens 16 selected.

Ainsi que représenté sur les figures, les moyens d'indexation sont formés par des crans 19 ménagés sur le bord périphérique du plateau 15 et coo- pérant avec une bille 20 déplaçable en translation sous l'action ressort 21 en direction du plateau 15. As shown in the figures, the indexing means are formed by notches 19 formed on the peripheral edge of the plate 15 and co-operating with a ball 20 displaceable in translation under the spring action 21 in the direction of the plate 15.

La bille 20 et le ressort 21 sont disposés dans logement 22 ménagé dans le boîtier 2. The ball 20 and the spring 21 are arranged in housing 22 formed in the housing 2.

Pour permettre le positionnement d'une lentille en regard du réflecteur 8, un cran 19 est ménagé sur le bord périphérique plateau 15 au niveau de chaque lentille 16. To allow the positioning of a lens opposite the reflector 8, a notch 19 is formed on the peripheral edge of the plate 15 at the level of each lens 16.

La bille 20 permet donc l'indexation précise du plateau 15 en ro tation afin de focaliser une lentille 16 dans l'axe du réflecteur 8 la source lumi neuse 7. The ball 20 therefore allows the precise indexing of the plate 15 in rotation in order to focus a lens 16 in the axis of the reflector 8 the light source 7.

dispositif d'éclairage selon l'invention permet donc, par une simple rotation plateau au moyen de la molette associée à plateau, d'avoir un choix étendu possibilités d'éclairage à partir d'une seule source lumineuse.lighting device according to the invention therefore allows, by a simple rotation of the plate by means of the wheel associated with the plate, to have a wide choice of lighting possibilities from a single light source.
