Description

BLOC OPTIQUE À RÉFLECTEUR INDEXÉ PAR LE MASQUE  OPTICAL BLOCK WITH REFLECTOR INDEXED BY THE MASK
L’invention concerne les blocs optiques, éventuellement de véhicules, assurant au moins une fonction photométrique de signalisation ou d’éclairage. The invention relates to optical units, possibly of vehicles, providing at least one photometric signaling or lighting function.
Certains blocs optiques, généralement destinés à équiper des véhicules, éventuellement automobile, comprennent au moins un bloc optique comportant un boîtier et une glace solidarisée fixement à une partie avant du boîtier. Ce boîtier délimite un espace interne qui loge au moins une source de photons associée à un réflecteur et à un masque participant ensemble à au moins une fonction photométrique de signalisation ou d’éclairage.  Certain optical units, generally intended for equipping vehicles, possibly motor vehicles, comprise at least one optical unit comprising a housing and a lens fixedly attached to a front part of the housing. This housing delimits an internal space which houses at least one photon source associated with a reflector and with a mask participating together in at least one photometric signaling or lighting function.
Pour que la fonction photométrique soit correctement assurée, il est indispensable que le réflecteur soit précisément positionné, avec un bon iso statisme, par rapport au boîtier de son bloc optique, suivant trois directions perpendiculaires entre elles. Pour obtenir ce positionnement précis et ce bon iso-statisme, le réflecteur est habituellement solidarisé au boîtier au moyen de vis, ce qui nécessite de prévoir des pattes de fixation sur le boîtier et/ou sur le réflecteur, et donc complexifie et augmente les coûts du moule du boîtier et/ou du moule du réflecteur. En outre, cela complexifie et donc rend plus onéreux l’assemblage du bloc optique. For the photometric function to be correctly ensured, it is essential that the reflector is precisely positioned, with good isostaticness, relative to the housing of its optical unit, in three directions perpendicular to each other. To obtain this precise positioning and this good isostaticism, the reflector is usually secured to the housing by means of screws, which requires the provision of fixing lugs on the housing and / or on the reflector, and therefore complicates and increases costs. of the housing mold and / or of the reflector mold. In addition, this complicates and therefore makes the assembly of the optical unit more expensive.
L’invention a notamment pour but d’améliorer la situation.  The invention aims in particular to improve the situation.
Elle propose notamment à cet effet un bloc optique comprenant, d’une part, un boîtier délimitant un espace interne logeant au moins une source de photons associée à un réflecteur et à un masque participant ensemble à au moins une fonction photométrique, et, d’autre part, une glace solidarisée fixement à une partie avant du boîtier.  To this end, it notably proposes an optical unit comprising, on the one hand, a housing delimiting an internal space housing at least one photon source associated with a reflector and with a mask participating together in at least one photometric function, and, on the other hand, a glass fixedly attached to a front part of the housing.
Ce bloc optique se caractérise par le fait que :  This optical unit is characterized by the fact that:
- son masque comprend une partie arrière opposée à la glace et comportant un plot (ou fût) muni d’un trou fileté coopérant avec une vis traversant un trou correspondant défini dans une paroi arrière du boîtier, et d’au moins une ailette d’indexage définie suivant une direction choisie, et  - Its mask includes a rear part opposite the glass and comprising a stud (or barrel) provided with a threaded hole cooperating with a screw passing through a corresponding hole defined in a rear wall of the housing, and at least one fin. indexing defined in a chosen direction, and
- son réflecteur comprend une partie arrière interposée entre la paroi arrière du boîtier et la partie arrière (correspondante) du masque et munie d’une ouverture présentant une forme homologue à une forme du plot et traversée par une partie d’extrémité de ce dernier afin que le réflecteur soit indexé en position par rapport au masque suivant cette direction choisie tout en l’immobilisant par rapport à la paroi arrière du boîtier. - its reflector includes a rear part interposed between the rear wall of the housing and the rear (corresponding) part of the mask and provided with an opening having a shape homologous to a shape of the stud and crossed by an end part of the latter so that the reflector is indexed in position relative to the following mask this direction chosen while immobilizing it relative to the rear wall of the housing.
On obtient ainsi un positionnement et un iso-statisme naturels du réflecteur par rapport au boîtier par le biais du masque, sans qu’il faille prévoir des moyens de fixation dédiés du réflecteur sur ce boîtier. This gives natural positioning and isostatic nature of the reflector relative to the housing by means of the mask, without the need for dedicated fixing means for the reflector on this housing.
Le bloc optique selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :  The optical unit according to the invention may include other characteristics which can be taken separately or in combination, and in particular:
- son masque peut comprendre deux parties arrière opposées à la glace et comportant respectivement deux plots munis d’ailettes d’indexage définies respectivement suivant deux directions perpendiculaires entre elles. Dans ce cas, son réflecteur comprend deux parties arrière interposées entre la paroi arrière du boîtier et respectivement les deux parties arrière du masque et munies respectivement d’ouvertures présentant des formes homologues aux formes respectives de ces deux plots et traversées respectivement par des parties d’extrémité de ces derniers afin que le réflecteur soit indexé en position par rapport au masque suivant respectivement ces deux directions tout en l’immobilisant par rapport à la paroi arrière du boîtier ;  - His mask may include two rear parts opposite the glass and respectively comprising two studs provided with indexing fins defined respectively in two directions perpendicular to each other. In this case, its reflector comprises two rear parts interposed between the rear wall of the housing and respectively the two rear parts of the mask and respectively provided with openings having shapes homologous to the respective shapes of these two studs and crossed respectively by parts of end of the latter so that the reflector is indexed in position relative to the mask respectively in these two directions while immobilizing it relative to the rear wall of the housing;
- chaque plot peut être muni sur sa périphérie, en deux endroits opposés, de deux ailettes d’indexage définies dans un même plan parallèle à la direction choisie concernée,  - each pad can be provided on its periphery, in two opposite places, with two indexing fins defined in the same plane parallel to the chosen direction concerned,
- son réflecteur peut comprendre une face arrière orientée vers la paroi arrière du boîtier et munie, à proximité de chaque ouverture, d’au moins deux protubérances contactant cette paroi arrière du boîtier en positionnant le réflecteur par rapport à la paroi arrière du boîtier suivant une autre direction choisie, perpendiculaire à chaque direction choisie d’une ailette d’indexage ;  its reflector may include a rear face oriented towards the rear wall of the housing and provided, near each opening, with at least two protrusions contacting this rear wall of the housing by positioning the reflector relative to the rear wall of the housing according to a another chosen direction, perpendicular to each chosen direction of an indexing fin;
la face arrière de son réflecteur peut être munie autour de chaque ouverture de quatre protubérances présentant des orientations différant deux à deux de 90° ; the rear face of its reflector can be fitted around each opening of four protuberances having orientations differing two by two by 90 °;
- il peut constituer un feu arrière d’un véhicule ;  - it can constitute a rear light of a vehicle;

L’invention propose également un véhicule, éventuellement de type automobile, et comprenant au moins un bloc optique du type de celui présenté ci-avant.  The invention also provides a vehicle, possibly of the automotive type, and comprising at least one optical unit of the type presented above.
D’autres caractéristiques et avantages de l’invention apparaîtront à l’examen de la description détaillée ci-après, et des dessins annexés (obtenus en CAO/DAO (« Conception Assistée par Ordinateur/Dessin Assisté par Ordinateur »), d’où le caractère apparemment discontinu de certaines lignes), sur lesquels :  Other characteristics and advantages of the invention will appear on examining the detailed description below, and the attached drawings (obtained in CAD / CAD (“Computer Aided Design / Computer Aided Drawing”), whence the apparently discontinuous nature of certain lines), on which:

- la figure 5 illustre de façon schématique, dans une vue en perspective du côté arrière, une partie du bloc optique de la figure 1 , contenant un second plot du masque traversant partiellement une seconde ouverture du réflecteur. - Figure 5 illustrates schematically, in a perspective view from the rear side, a part of the optical unit of Figure 1, containing a second mask stud partially passing through a second opening of the reflector.
L’invention a notamment pour but de proposer un bloc optique BO assurant au moins une fonction photométrique, et comportant un masque M assurant notamment l’indexage en position de son réflecteur RP.  The object of the invention is in particular to propose an optical unit BO ensuring at least one photometric function, and comprising a mask M ensuring in particular the indexing in position of its reflector RP.
Dans ce qui suit, on considère, à titre d’exemple non limitatif, que le bloc optique BO est destiné à équiper un véhicule automobile. Mais l’invention n’est pas limitée à cette application. En effet le bloc optique BO peut équiper tout appareil, système, installation ou bâtiment, et notamment tout véhicule (terrestre, maritime (ou fluvial), ou aérien) devant assurer au moins une fonction photométrique d’éclairage ou de signalisation.  In what follows, it is considered, by way of nonlimiting example, that the optical unit BO is intended to equip a motor vehicle. But the invention is not limited to this application. Indeed, the optical unit BO can equip any device, system, installation or building, and in particular any vehicle (land, sea (or river), or air) having to provide at least one photometric lighting or signaling function.
Par ailleurs, on considère dans ce qui suit, à titre d’exemple non limitatif, que le bloc optique BO est un feu arrière. Par exemple, ce feu arrière peut équiper une partie d’un hayon arrière ou d’une porte de coffre arrière ou d’une aile arrière de véhicule. Mais le bloc optique pourrait également être un feu avant ou un projecteur (ou phare) avant. Furthermore, it is considered in what follows, by way of nonlimiting example, that the optical unit BO is a rear light. For example, this rear light can be fitted to part of a tailgate or a rear trunk door or a rear wing of a vehicle. But the optical unit could also be a front light or a headlight (or headlight).
Sur les figures 1 à 5, la direction X est la direction longitudinale du véhicule, laquelle est parallèle aux côtés latéraux comportant les portières latérales, la direction Y est la direction transversale du véhicule, laquelle est perpendiculaire aux côtés latéraux et à la direction longitudinale X, et la direction Z est la direction verticale du véhicule, laquelle est perpendiculaire aux directions longitudinale X et transversale Y.  In FIGS. 1 to 5, the direction X is the longitudinal direction of the vehicle, which is parallel to the lateral sides comprising the side doors, the direction Y is the transverse direction of the vehicle, which is perpendicular to the lateral sides and to the longitudinal direction X , and the direction Z is the vertical direction of the vehicle, which is perpendicular to the longitudinal X and transverse Y directions.
On a schématiquement illustré sur les figures 1 à 3 une partie d’un exemple de bloc optique BO selon l’invention (ici un feu arrière de véhicule automobile).  There is diagrammatically illustrated in FIGS. 1 to 3 part of an example of an optical unit BO according to the invention (here a rear light of a motor vehicle).
Comme illustré un bloc optique BO, selon l’invention, comprend, d’une part, un boîtier BB délimitant un espace interne logeant notamment au moins une source de photons (non représentée), un masque M et un réflecteur RP participant ensemble à au moins une fonction photométrique, et, d’autre part, une glace GL solidarisée fixement à une partie avant du boîtier BB.  As illustrated, an optical unit BO, according to the invention, comprises, on the one hand, a housing BB delimiting an internal space housing in particular at least one photon source (not shown), a mask M and a reflector RP participating together in the less a photometric function, and, on the other hand, a glass GL fixedly secured to a front part of the housing BB.
On considère dans ce qui suit, à titre d’exemple non limitatif, que la fonction photométrique assurée par le bloc optique BO est une fonction de feu de position (ou veilleuse ou encore lanterne). Mais il pourrait s’agir d’une autre fonction photométrique, comme par exemple une fonction de feu de jour (ou DRL (Daytime running Light (ou Lamp) - signalisation lumineuse allumée automatiquement lorsque le véhicule est mis en fonctionnement pendant le jour)), une fonction d’indicateur de changement de direction (ou clignotant), une fonction feu de stop, une fonction de feu de recul, une fonction de feu de route, une fonction de feu de croisement, ou une fonction de feu antibrouillard. It is considered in what follows, by way of nonlimiting example, that the photometric function provided by the optical unit BO is a position light function (or pilot light or lantern). But it could be another photometric function, such as for example a daytime running light function (or DRL (Daytime running Light (or Lamp) - light signal switched on automatically when the vehicle is put into operation during the day)) , a direction change indicator (or flashing) function, a stop light function, a reversing light function, a high beam function, a dipped beam function, or a fog light function.
La glace GL est solidarisée fixement (par exemple par soudage GL glass is fixedly secured (for example by welding
(éventuellement par vibrations) ou collage) et de façon étanche à la partie avant du boîtier BB. Elle peut être réalisée en matière plastique (ou synthétique) transparente ou bien en verre, et peut être éventuellement colorée au moins en partie, par exemple en rouge ou en orange. (possibly by vibration) or bonding) and tightly to the front part of the BB housing. It can be made of transparent plastic (or synthetic) or glass, and can optionally be colored at least in part, for example in red or orange.
La (chaque) source de photons participant à la fonction photométrique précitée (assurée par le bloc optique BO) peut, par exemple, être installée sur une carte électronique qui est logée dans l’espace interne du bloc optique BO. Cette carte électronique peut, par exemple, être une carte à circuits imprimés de type PCB (« Printed Circuit Board »).  The (each) photon source participating in the aforementioned photometric function (provided by the optical block BO) can, for example, be installed on an electronic card which is housed in the internal space of the optical block BO. This electronic card can, for example, be a printed circuit board of the PCB (“Printed Circuit Board”) type.
Par exemple, la (chaque) source de photons peut comporter au moins une diode électroluminescente (ou LED). En variante, la (chaque) source de photons peut comporter au moins une diode laser ou un laser à gaz ou encore une lampe (ou ampoule).  For example, the (each) photon source may include at least one light-emitting diode (or LED). As a variant, the (each) photon source may comprise at least one laser diode or a gas laser or even a lamp (or bulb).
Le réflecteur RP est chargé de réfléchir des photons, issus de la (chaque) source de photons, en direction d’une partie de la glace GL, éventuellement via au moins un élément optique, comme par exemple une lentille ou un diffuseur. Il est par exemple réalisé par moulage d’une matière plastique.  The reflector RP is responsible for reflecting photons, coming from the (each) photon source, in the direction of part of the lens GL, possibly via at least one optical element, such as for example a lens or a diffuser. It is for example made by molding a plastic material.
Le masque M comprend une partie avant située au voisinage de la glace GL et définissant au moins en partie une zone de sortie pour les photons réfléchis par le réflecteur RP. Il peut aussi, éventuellement, participer à un effet de style de son bloc optique BO.  The mask M comprises a front part situated in the vicinity of the lens GL and defining at least partially an exit zone for the photons reflected by the reflector RP. It can also, possibly, participate in a style effect of its optical block BO.
De plus, et comme cela apparaît mieux sur les figures 1 et 3 à 5, ce masque M comprend au moins une partie arrière P1j qui est opposée à la glace GL et qui comporte un plot (ou fût) Plj d’indexage de position. Ce dernier (Plj) est muni d’un trou fileté qui coopère avec une vis Vj traversant un trou correspondant défini dans une paroi arrière PB du boîtier BB (voir figure 3), et d’au moins une ailette d’indexage Aj qui est définie suivant une direction choisie (ici du véhicule), comme par exemple la direction transversale Y ou la direction verticale Z. In addition, and as is best seen in Figures 1 and 3 to 5, this mask M includes at least one rear part P1j which is opposite to the glass GL and which comprises a position indexing pad (or barrel) Plj. The latter (Plj) is provided with a threaded hole which cooperates with a screw Vj passing through a corresponding hole defined in a rear wall PB of the housing BB (see FIG. 3), and at least one indexing fin Aj which is defined according to a chosen direction (here of the vehicle), such as for example the transverse direction Y or the vertical direction Z.
De son côté, le réflecteur RP comprend aussi au moins une partie arrière P2j qui est interposée entre la paroi arrière PB du boîtier BB et la partie arrière P1j correspondante du masque M (voir figure 3) et qui est munie d’une ouverture Oj présentant une forme homologue à la forme du plot (ou fût) Plj correspondant. Comme cela apparaît mieux sur les figures 1 et 3 à 5, cette ouverture Oj est traversée par une partie d’extrémité libre de ce plot Plj correspondant afin que le réflecteur RP soit indexé en position par rapport au masque M suivant la direction choisie (ici Z ou Y) de chaque ailette d’indexage Aj de ce plot Plj tout en l’immobilisant par rapport à la paroi arrière PB du boîtier BB grâce à la vis Vj correspondante qui est vissée dans le trou fileté de ce plot Plj (voir figures 2 et 3).  For its part, the reflector RP also comprises at least one rear part P2j which is interposed between the rear wall PB of the housing BB and the corresponding rear part P1j of the mask M (see FIG. 3) and which is provided with an opening Oj having a shape homologous to the shape of the corresponding plot (or barrel) Plj. As appears better in FIGS. 1 and 3 to 5, this opening Oj is crossed by a free end part of this corresponding stud Plj so that the reflector RP is indexed in position relative to the mask M in the chosen direction (here Z or Y) of each indexing fin Aj of this stud Plj while immobilizing it with respect to the rear wall PB of the housing BB by means of the corresponding screw Vj which is screwed into the threaded hole of this stud Plj (see figures 2 and 3).
On comprendra que le logement de la partie d’extrémité libre d’un plot Plj (avec chaque ailette d’indexage Aj orientée suivant une direction choisie Z ou Y) dans l’ouverture Oj correspondante du réflecteur RP permet d’indexer en position ce réflecteur RP par rapport au masque M suivant cette direction choisie Z ou Y. Dans le même temps, la partie arrière P2j du réflecteur RP, qui contient cette ouverture Oj, est interposée entre la paroi arrière PB du boîtier BB et la partie arrière P1j du masque M qui contient ce plot Plj, et donc le vissage de la vis Vj (qui traverse un trou de la paroi arrière PB du boîtier BB) dans le trou fileté de ce plot Plj assure l’immobilisation de cette partie arrière P2j du réflecteur RP par rapport à la paroi arrière PB du boîtier BB.  It will be understood that the housing of the free end part of a pad Plj (with each indexing fin Aj oriented in a chosen direction Z or Y) in the corresponding opening Oj of the reflector RP makes it possible to index in position this reflector RP relative to the mask M in this chosen direction Z or Y. At the same time, the rear part P2j of the reflector RP, which contains this opening Oj, is interposed between the rear wall PB of the housing BB and the rear part P1j of the mask M which contains this stud Plj, and therefore the screwing of the screw Vj (which passes through a hole in the rear wall PB of the housing BB) in the threaded hole of this stud Plj ensures the immobilization of this rear part P2j of the reflector RP relative to the rear wall PB of the housing BB.
Le positionnement et l’iso-statisme du réflecteur RP suivant au moins une direction se font donc naturellement par rapport au boîtier BB par le biais du masque M, sans qu’il faille prévoir des moyens de fixation dédiés du réflecteur RP sur ce boîtier BB. The positioning and the isostaticness of the reflector RP in at least one direction is therefore naturally relative to the housing BB by means of the mask M, without it being necessary to provide dedicated fixing means for the reflector RP on this housing BB .
Dans l’exemple illustré non limitativement sur les figures 1 à 5, le masque M comprend deux première P1 1 (j = 1 ) et seconde P 12 ( j = 2) parties arrière opposées à la glace GL, et le réflecteur RP comprend deux première P21 (j = 1 ) et seconde P22 (j = 2) parties arrière interposées entre la paroi arrière PB du boîtier BB et respectivement les première P1 1 et seconde P12 parties arrière du masque M. In the example illustrated without limitation in FIGS. 1 to 5, the mask M comprises two first P1 1 (j = 1) and second P 12 (j = 2) rear parts opposite to the glass GL, and the reflector RP comprises two first P21 (j = 1) and second P22 (j = 2) rear parts interposed between the rear wall PB of the housing BB and respectively the first P1 1 and second P12 rear parts of the mask M.
Comme illustré sur les figures 1 , 3 et 4, la première partie arrière P1 1 du masque M comprend un premier plot PU muni d’au moins une ailette d’indexage A1 définie suivant une première direction (ici la direction verticale Z). Comme illustré sur les figures 1 et 5, la seconde partie arrière P12 du masque M comprend un second plot PI2 muni d’au moins une ailette d’indexage A2 définie suivant une seconde direction (ici la direction transversale Y) qui est perpendiculaire à la première direction (ici Z).  As illustrated in FIGS. 1, 3 and 4, the first rear part P1 1 of the mask M comprises a first pad PU provided with at least one indexing fin A1 defined in a first direction (here the vertical direction Z). As illustrated in FIGS. 1 and 5, the second rear part P12 of the mask M comprises a second pad PI2 provided with at least one indexing fin A2 defined in a second direction (here the transverse direction Y) which is perpendicular to the first direction (here Z).
Comme illustré sur les figures 1 , 3 et 4, la première partie arrière P21 du réflecteur RP comprend une première ouverture 01 qui présente une première forme homologue à la première forme du premier plot PU et qui est traversée par la partie d’extrémité de ce premier plot PU afin que le réflecteur RP soit indexé en position par rapport au masque M suivant la première direction (ici Z), tout en l’immobilisant par rapport à la paroi arrière PB du boîtier BB grâce à la première vis V1 vissée dans le trou fileté du premier plot PU . Comme illustré sur les figures 1 et 5, la seconde partie arrière P22 du réflecteur RP comprend une seconde ouverture 02 qui présente une seconde forme homologue à la seconde forme du second plot PI2 et qui est traversée par la partie d’extrémité de ce second plot PI2 afin que le réflecteur RP soit indexé en position par rapport au masque M suivant la seconde direction (ici Y), tout en l’immobilisant par rapport à la paroi arrière PB du boîtier BB grâce à la seconde vis V2 vissée dans le trou fileté du second plot PI2.  As illustrated in FIGS. 1, 3 and 4, the first rear part P21 of the reflector RP comprises a first opening 01 which has a first shape homologous to the first shape of the first pad PU and which is crossed by the end part of this first pad PU so that the reflector RP is indexed in position relative to the mask M in the first direction (here Z), while immobilizing it relative to the rear wall PB of the housing BB by means of the first screw V1 screwed into the threaded hole of the first PU pad. As illustrated in FIGS. 1 and 5, the second rear part P22 of the reflector RP comprises a second opening 02 which has a second form homologous to the second form of the second stud PI2 and which is crossed by the end part of this second stud PI2 so that the reflector RP is indexed in position relative to the mask M in the second direction (here Y), while immobilizing it relative to the rear wall PB of the housing BB by means of the second screw V2 screwed into the threaded hole of the second PI2 stud.
Grâce à ce mode de réalisation illustré, le positionnement et l’iso statisme du réflecteur RP suivant les deux directions Z et Y se font naturellement par rapport au boîtier BB par le biais du masque M, sans qu’il faille prévoir des moyens de fixation dédiés du réflecteur sur ce boîtier BB. Thanks to this illustrated embodiment, the positioning and the static droop of the reflector RP in the two directions Z and Y take place naturally with respect to the housing BB by means of the mask M, without the need for fixing means. dedicated to the reflector on this BB box.
Par exemple, et comme illustré non limitativement sur les figures 1 , 4 et 5, chaque plot Plj peut être muni sur sa périphérie, en deux endroits opposés, de deux ailettes d’indexage Aj qui sont définies dans un même plan parallèle à la direction choisie (ici Z ou Y). Lorsque le plot Plj est de forme générale cylindrique circulaire, ses deux ailettes d’indexage Aj sont définies respectivement en deux endroits de sa périphérie qui sont diamétralement opposés, et s’étendent radialement selon des sens opposés depuis cette périphérie. Cette option permet d’améliorer le positionnement et l’iso-statisme du réflecteur RP suivant la direction (Z ou Y) concernée. Mais dans une variante de réalisation non illustrée chaque plot Plj pourrait n’être muni sur sa périphérie que d’une seule ailette d’indexage Aj, en un seul endroit. For example, and as illustrated without limitation in FIGS. 1, 4 and 5, each pad Plj can be provided on its periphery, in two opposite locations, with two indexing fins Aj which are defined in the same plane parallel to the chosen direction (here Z or Y). When the stud Plj is of generally circular cylindrical shape, its two indexing fins Aj are defined respectively at two places on its periphery which are diametrically opposite, and extend radially in opposite directions from this periphery. This option improves the positioning and isostaticness of the reflector RP according to the direction (Z or Y) concerned. But in a variant embodiment not shown, each pad Plj could be provided on its periphery with only one indexing fin Aj, in one place.
Egalement par exemple, et comme illustré non limitativement sur les figures 1 et 3 à 5, le réflecteur RP peut comprendre une face arrière FR orientée vers la paroi arrière PB du boîtier BB et munie d’au moins deux protubérances PRj à proximité de chaque ouverture Oj. Ces protubérances PRj sont agencées de manière à contacter cette paroi arrière PB du boîtier BB en positionnant le réflecteur RP par rapport à la paroi arrière PB du boîtier BB suivant une autre (troisième) direction choisie (ici la direction longitudinale X) qui est perpendiculaire à chaque direction choisie (ici Z ou Y) d’une ailette d’indexage Aj.  Also for example, and as illustrated without limitation in FIGS. 1 and 3 to 5, the reflector RP may include a rear face FR oriented towards the rear wall PB of the housing BB and provided with at least two protuberances PRj near each opening Oj. These protrusions PRj are arranged so as to contact this rear wall PB of the housing BB by positioning the reflector RP relative to the rear wall PB of the housing BB in another (third) chosen direction (here the longitudinal direction X) which is perpendicular to each chosen direction (here Z or Y) of an Aj indexing fin.
On comprendra en effet que lorsque les protubérances PRj d’une partie arrière P2j du réflecteur RP sont au contact de la paroi arrière PB du boîtier BB, cela signifie que cette partie arrière P2j est correctement positionnée suivant la troisième direction (ici X).  It will in fact be understood that when the protrusions PRj of a rear part P2j of the reflector RP are in contact with the rear wall PB of the housing BB, this means that this rear part P2j is correctly positioned in the third direction (here X).
On notera que dans l’exemple illustré non limitativement sur les figures 1 et 3 à 5, la face arrière FR du réflecteur RP est munie autour de chaque ouverture Oj de quatre protubérances PRj qui présentent des orientations différant deux à deux de 90° . Mais laface arrière FR du réflecteur RP pourrait être munie autour de chaque ouverture Oj de moins de quatre protubérances PRj, comme par exemple deux (présentant des orientations différant de 180°) ou bien trois (présentant des oifentations différant deux à deux de 120°).  Note that in the example illustrated without limitation in FIGS. 1 and 3 to 5, the rear face FR of the reflector RP is provided around each opening Oj with four protrusions PRj which have orientations differing two by two by 90 °. However, the rear face FR of the reflector RP could be provided around each opening Oj with less than four protuberances PRj, such as for example two (having orientations differing by 180 °) or else three (having orifices differing two by two by 120 °) .

- elle permet de garantir le positionnement et l’iso-statisme du réflecteur suivant au moins une direction, - elle permet de simplifier l’assemblage du bloc optique, - it makes it possible to guarantee the positioning and the isostatic nature of the reflector in at least one direction, - it simplifies the assembly of the optical unit,
