    [0001] TECHNICAL FIELD The present invention relates to the field of motor vehicle light devices, in particular light devices comprising light guides. In particular, the present invention relates to a vehicle light device comprising two light guides fixed to each other so that one of the guides supports the other in said light device. JP2012190761 discloses a vehicle light device, in which an intermediate guide transmits a luminous flux along its length. This intermediate guide carries terminal guides and also includes prisms for redirecting certain rays of this flow within these terminal guides. However, the degrees of freedom of orientation of the intermediate guide and the end guides are limited. Precise orientations must be observed to arrange these 20 different terminal guides by fixing them to the main guide in order to be able to connect them. In addition, the angle of incidence of the terminal guides to the main guide is disclosed as having to respect a precise angle. The technical problem that the invention aims to solve is therefore to find an arrangement of light guides, one of which carries the other, allowing a greater freedom of realization, especially of orientation of these guides relative to each other. to others. For this purpose, a first object of the invention is a vehicle light device comprising a first light guide and a second light guide, each intended to emit at least a portion of a light function, these two guides being two distinct parts, said first light guide comprising: - a main light guiding part comprising an input diopter intended to receive light rays from a light source and a main output diopter notably in front of the input diopter the main guide part being arranged in such a way that a first part of the light rays passing through the input diopter are guided to the main output diopter, and pass through it for example, - a fixing part fixing this main portion to the second light guide and extending between this main portion and the second guide so that one of the guides supports the other in said ispositif bright. Thus, the second light guide has more degrees of freedom with respect to the fixing portion of the first guide, and therefore with respect to the first guide itself. In particular, it is possible to orient the main guide portion of the light guides parallel to each other.
    [0002] The light device according to the invention may optionally have one or more of the following characteristics: the fixing part is integrally formed in one piece with the main guiding part; this allows a simpler embodiment, the attachment portion being already positioned relative to one of the guides; the fixing portion of the first light guide and the second light guide are nested one inside the other; this attachment is simple to achieve, in particular it facilitates the molding of fasteners; a screw passes through the nested portions of said second light guide and the fixing portion of the first light guide; this makes it possible to secure the fixation; the second light guide also comprises a main light guiding part comprising an input diopter intended to receive light rays from another light source and a main output diopter located in particular in front of the input diopter, the guiding main portion being arranged so that a first portion of the light rays passing through the input diopter is guided to the main output diopter, and crosses for example; this leaves more degrees of freedom because the second light guide can receive light rays from a light source specifically dedicated to it; there is therefore no need to respect a certain orientation of the two light guides with respect to one another so that light rays pass from the first guide to the second light guide; the second light guide also includes a fixing portion attached to the first light guide; the fixing portion of the second light guide is fixed to the attachment portion of the first light guide; the degrees of freedom of attachment of a guide to the other are therefore the same as those of the attachment of these two fixing parts; in other words the orientation of the two guides can be done independently although one of them carries the other; the fixing part or parts comprise fixing means ensuring the fixing of the corresponding fixing part; the fixing portion of one of the light guides comprises an ear or a receiving shaft, the fixing portion of the other of the light guides comprising a pin 30 or a shaft adapted to fit into said ear or said reception barrel; it is a simple means for producing fixing means by molding; a fixing rod, in particular a screw or a rivet, passing through both said ear or said reception shaft and said tongue or said shaft able to fit together; - For one or for each light guide, said fixing portion 5 is integral with the guide comprising the fixing portion; said fixing part or portions form light guiding secondary parts, the main guiding part and the fixing part of the first light guide and / or the second light guide being arranged in such a way that a second part of the light rays passing through the input diopter of the corresponding guide are guided inside the corresponding fixing part, the latter comprising decoupling means distributed along a decoupling portion of this fixing part so as to that rays escape along it; this also makes it possible to use this fixing part to extend the illuminating surface of the light functions and / or to illuminate the luminous device; The fixing part or portions form at least one step between the decoupling portion and the fixing means of the same light guide; this recess allows a controlled leakage of the rays at the level of this recess, and to choose where the rays will be able to go away; A concealer is positioned in front of the one or more means for fixing the one or more light guides so as to mask this or these means of attachment for an observer outside said luminous device; the recess and the concealer are arranged in such a way that the rays issuing at the recess and between the recess and the fixing means are obscured by the concealer; this is particularly advantageous in the context of the invention, since the attachment is offset by a diffusing secondary portion and the remaining rays reaching its end will be absorbed by this occulter; for one or for each light guide, the main guide part of this guide comprises a reflection portion able to reflect said second portion of the light rays towards and to the inside of said secondary guide portion of this guide; it is an embodiment for deflecting a portion of the light rays in the guide secondary portion; for one or each guide, said reflection portion forms a narrowing of the corresponding main guiding portion so that it intercepts a portion of the light rays from the input diopter; this mode makes it possible to simply carry out the reflection portion; for one or for each guide, said main guiding part comprises: an upstream portion extending from the input diopter to said reflection portion, a downstream portion extending from said reflection portion towards the diopter of main outlet, the downstream portion having a thickness less than that of the upstream portion; this makes it easier to achieve shrinkage; the rear of the corresponding fixing portion joins said upstream portion at an acute angle, seen from outside the guide, and the front of this guide fixing portion joins said upstream portion forming a curve whose rope forms an obtuse angle with said downstream portion, seen from outside the light device; the reflection portion is formed by an inclined pan; - The reflection portion is vis-à-vis said junction area; each fixing part is curved and is, seen from the outside of the guide, concave at the front and convex at the rear; the fixing parts form an arc of a circle; - It comprises a casing formed by a housing and a closing window of the housing, one of the light guides being supported in the housing by the other light guide; it comprises the light source (s), in particular one or more light-emitting diodes (s), arranged to emit light rays through the diopter (s) entrance; for each of said first and second light guides, a first part of the light rays forms, when leaving the main output diopter of the corresponding light guide, part or all of a signaling and / or lighting function of the road, in particular a stop light, a direction indicator and / or a reversing light; the fixing part comprises decoupling means distributed along this decoupling secondary part so that rays escape along the latter, these rays forming an illumination halo of the interior of said decoupling part; envelope; this makes it possible to confer a night signature enabling the optical components and the mask (s) of the night light device to be seen; this is particularly advantageous in embodiments according to which the vehicle light device is a signaling device, such as a rear light, or a road lighting device, such as a searchlight; it comprises a mask partially covering the main guiding part of the first light guide; the reflection portion of this guide may be arranged so that its outer surface forms a stop on which said mask is positioned; thus minimizing the number of particular portions to be molded, which simplifies the molding of the parts, in particular the first light guide, but also the number of positions to be made during assembly of the vehicle light device; - Similarly or alternately the device may comprise a mask partially covering the main guide portion of the second light guide; the reflection portion of this guide may be arranged so that its outer surface forms a stop on which said mask is positioned; - The mask (s) is (are) formed (s) by a sleeve wherein the corresponding main guiding portion is fitted; the first guide and / or the second light guide thus also serve to accurately position the mask (s); according to an exemplary embodiment, the mask or masks comprise a complementary shape in contact with the outer surface of the corresponding reflection portion; it is thus simply the positioning of the mask or masks when they are fitted; the sleeve or sleeves comprise a counterform complementary to and in contact with the external surface of the corresponding reflection portion; the vehicle light device is a signaling light, in particular a vehicle rear lamp, a road lighting device, in particular a headlamp, or a lighting device for the interior of the passenger compartment; a vehicle, in particular a ceiling lamp or a wall lamp. Another object of the invention is a vehicle comprising a light guide and / or a light device according to the invention.
    [0003] The terms "upstream" and "downstream" in the present application refer to the direction of travel, along a light-guiding portion, of rays from the light source.
    [0004] The terms "forward" and "backward" refer to the direction of light emission from the input diopter of the main guide portion to its main output diopter. Other features and advantages of the invention will appear on reading the detailed description of the following nonlimiting examples, for the understanding of which reference will be made to the appended drawings, among which: FIG. 1 represents a detail of FIG. 2. Figure 2 shows a vehicle light device according to the invention. - Figure 3 shows a detail of a light guide according to an embodiment applied in the device of the invention, in particular the junction between the main guide portion and the secondary guide portion, seen in perspective. - Figure 4 shows a light guide according to an alternative embodiment of the junction between the main guide portion and the secondary guide portion illustrated in Figure 3, seen in perspective. FIG. 5 represents a longitudinal section of the light guides of FIG. 4 or 5. FIGS. 1 and 2 illustrate a vehicle light device 260 according to the invention. This light device 260 comprises a housing 262 and a closing window 264, which closes a front opening of the housing 262. The housing 262 and the closing window 264 thus delimit an envelope 261 of the light device 260. This closing window 264 is in transparent material and may be of polymer or glass.
    [0005] A first light guide 201 is placed inside this envelope 261. As illustrated, it is supported in this housing 262 by a second light guide 201 ', the latter being fixed to the housing, in particular to the upper wall of the case. Alternatively, the light device can be made so that the second light guide 201 'rests on the first light guide 201 and is thus carried by the latter, this first light guide 201 can for example be fixed on the wall lower case 262. As illustrated in Figure 1, according to an exemplary embodiment of the invention, the first light guide 201 comprises a main guide portion 210 fixed by means of a fixing portion formed by a guiding abutment 220 of light, this fixing portion forming a fixing lug. In other words, the first light guide 201 has a fixing lug inside which are propagated light rays R2 and R3, and is therefore also a light guiding part.
    [0006] The first light guide 201 is arranged to allow propagation of light in this main portion 210, for example by internal reflection, from an input diopter 212 to a main output diopter 218.
    [0007] The first light guide 201 is intended to receive light rays R1, R2, R3 from a light source 251. These radii R1, R2 first pass through the input diopter 212 of the main guiding part 210, and then propagate within a first portion, said upstream portion 214, of the main guide portion 210. This upstream portion 214 extends from the input diopter 212 to a reflection portion 216 , and up to a junction zone 222 of the main guide portion 210 and the attachment portion 220.
    [0008] In the alignment of this upstream portion 214, the main guide portion 210 extends downstream of the reflection portion 216 by a downstream portion 217. The latter ends with the main output diopter 218.
    [0009] This reflection portion 216 makes it possible to intercept a second portion of radii R2, R3, the first portion of radii R1 being that which is not intercepted. Thus, the first portion of the spokes R1 will pass into the main guide portion 210, adjacent this reflection portion 216, and propagate in the downstream portion 217 to the main exit diopter 218. The light guide 201 is for example arranged so that these light rays R1 are the majority of the rays R1 and R2, R3, received by the input diopter 212, so that the light guide 201 can achieve, alone or in part, a beam bright signaling or road lighting. On the other hand, the second portion of radii R2, R3, will meet the reflection portion 16, 116 and be reflected by it. The reflection portion is arranged to return these rays R2, R3 to the junction area 222 of the two guide portions. They will then enter the attachment portion 220, which also forms the guide secondary portion. This reflection portion 216 and the guide secondary portion 220 are arranged in such a way that this second portion of radii R2 then propagates along the guide secondary portion 220. The secondary guide portion 220, and therefore the fixing lug of the light guide 201 comprises an attachment portion 229 comprising a fixing means, formed in this example by a first shank 227 in which a stud 227 'of complementary shape fits. This post 227 'comes from the second light guide 201'.
    [0010] The stud 227 'is also barrel-shaped and has a central hole aligned with the through-hole of the first barrel 227. A screw 234 passes through the first barrel 227 and screws into the stud 227'.
    [0011] As a result, the fixing lug / guiding abutment 220, and therefore the first light guide 201, is fixed in the light device 260, the second light guide 201 'serving as a support for the first light guide 201.
    [0012] The attachment portion 220 of this first light guide 201 has a decoupling portion. As illustrated in FIG. 1, the decoupling portion is situated between the fixing portion 229 and the junction zone 222. It comprises, on its rear face, decoupling means, formed in particular by prisms 200. The radii R2, R3 intercepted and reflected by a reflection portion 216, will be deflected to the junction area 222, cross the latter and enter the fixing portion 220, then propagate in this decoupling portion by internal reflection on its walls. However, as and when they progress, some of these rays R3 will encounter decoupling means, in particular faces of the prisms 200, arranged to return them to the front face 223 of the decoupling portion, with an angle such that they out of the fixing portion / guiding secondary portion 220 through this front face 223. These prisms 200 are distributed along or on the extent of the decoupling portion of the fastening portion, or guide secondary portion 220, for example on the extent of the rear face of the decoupling portion of the guiding secondary portion 220, these prisms reflecting in this case the rays to the front face 223. Thus the front face 223 of this decoupling portion will radiate on any its length, or over the entire extent of this front face 223, and thereby generate a luminous halo. This front face 223 of the decoupling portion is concave from the outside, its concavity being turned towards the closing mirror 264. This will make it possible to generate a luminous halo in the front space 265 of the light device 260, situated between the decoupling portion and the closure glass 264. This will thus create a diffuse illumination of the optical elements and masks 240, 240 ', in front of this decoupling portion. These optical elements and these masks are visible during the day through the closing glass. According to the embodiments including the decoupling portions, as the example shown, they will also be visible at night. Their shapes can therefore also be used for a night signature. The second light guide 201 'also has a main guide portion 210' from which extends a fixing portion 220 '. This main guiding part and this fixing part join at a junction zone 222 '. This attachment portion 220 'of the second light guide 201' may also form a guide secondary portion, as in the case of the first light guide 201. This is the case in the example illustrated. In front of the junction zone 222 'of the second light guide 201' is arranged an inclined face 216 ', to return to the guide secondary portion 220' a portion of the set of Rr rays arriving from the input diopter 212 'of the second light guide 201'. The pan is inclined in that it forms a non-zero angle with respect to the extension direction of the main portion of the light guide.
    [0013] This fixing portion or guiding secondary portion 220 'also comprises, on its rear face, decoupling means 200', distributed along a decoupling portion between the post 227 'and the junction zone 222' of the second guide. light 201 '. This decoupling portion of the attachment portion 220 'of the second light guide 201' also has a concave shape facing the closing lens 264 and also generates a light halo of the same type as that generated by the first light guide 201. In this embodiment, the first light guide 201 is located below the second light guide 201 ', along a vertical axis. The fixing portions, or guiding abutments 220 and 220 ', leave from the corresponding junction areas 222, 222' towards the rear, bending upwards, for the first light guide 201, and towards the back, curving downwards, for the second light guide 201 '. This will generate respectively a luminous halo upwards and forwards and a luminous halo downwards and forwards. Overall, the entire space before 265 will be illuminated. It is even possible to place elements, such as masks, or optical elements, in this space before 265 while maintaining a luminous halo diffusing around them. To reinforce this aspect, the decoupling portions of these two lightguides 201 and 201 'are arranged so as to form together a single concavity turned towards the closure glass 264.
    [0014] To hide the attachment between the shaft 227 and the post 227 ', it is possible to place a concealer with an occultation portion 230 in front of the shaft 227 and this pin 227'. According to the exemplary embodiment illustrated, this occluder has a passage 231, such as a through hole or a notch, through which the pin 227 'is connected to the decoupling portion of the secondary guide portion 220' of the second guide of light 201 '. Behind this passage, the occluder has an ear 232 whose through hole is traversed by the fixing screw 234, and sandwiched between the shaft 227 of the first light guide and the head of the screw 234. Generally speaking, beyond the illustrated example, the fixing lug of the first light guide, the fixing lug of the second light guide and the occluder are fixed in a linear stack, in particular each comprising an orifice, their orifices being traversed by a single fastening means, such as a screw. According to an exemplary embodiment, each guide secondary portion 220, 220 'of these light guides 201, 201' has a branch 226, 226 'between the corresponding decoupling portion and respectively the fixing shaft 227 and the fixing pin 227. . The passage of one of these decoupling portions to the corresponding branch 226, 226 'forms a recess or edge 225, 225'. The spokes R2 guided by the second guide portions 220, 220 'to these recesses 225, 225' or up to these corresponding branches 226, will be likely to exit the light guide 201, 201 '. In the absence of occluder, not only they may exit uncontrolled, but still out the edge, they may create an undesirable light spot. The occultor previously described allows to hide these rays R2. In particular, in the arrangement illustrated in FIGS. 1 and 2, the occulting portion 230 has a vertical face and a horizontal face making it possible to obscure the undesirable rays. In the embodiment illustrated in FIGS. 1 and 2, the majority of the light rays entering the light guides 201 and 201 'exit through their exit dioptres 218 and 218', situated at the end of their downstream portions 217, 217. . In this example, these will allow the generation of a signaling beam, in particular to respect the distribution and light intensity, also called photometry, of a signaling beam, including a stop light, or still a stop light for the first guide 201 and a reversing light for the second guide 201 '. As in the example illustrated, the invention makes it possible to arrange the light guides 201 and 201 'so that their main guide portions 210 and 210' are parallel, or that the global directions of emission of their beams light through their exit dioptres 218 and 218 'are parallel. This is particularly useful when the beams from these main parts participate in signaling functions, and all the more useful if they perform together the same signaling function. These exit dioptres 218 and 218 'may also include firing to disperse the light rays around the overall beam emission direction and thereby expand the beam. For aesthetic reasons, the downstream portions 217, 217 'of the main guide parts 210, 210' are covered with a mask 240, 240 '. The latter is in the form of a sleeve, fitted on the corresponding downstream portion 227, 227 '. This mask has a recess 242, 242 ', able to abut against the narrowing forming the reflection portion 216, 216'. In this example, the reflection portions 216, 216 'being inclined faces, the recesses of the masks 242, 242' are also inclined faces. This makes it possible to create a limit to the fit of these masks 240, 240 'and to position them. In Figure 2, only the mask 240 'of the second light guide 201' is pushed to the end. The downstream portions 227, 227 'protrude from these sleeves. This is not necessary as their light beams can come out but it is easier to achieve. The sides of these masks 240, 240 ', oriented towards the center of the front space 265, namely in this example, the upper side of the mask 240 of the first light guide 201 and the lower side of the mask 240' of the second guide of light 201 ', will be able to be illuminated by the luminous halo. To enhance the diffuse effect of the halo, it is possible to arrange these sides so as to make them reflective, for example by aluminizing them, or to make them diffusing. According to one embodiment, the mask 240 'of the second guide comprises an upper portion in this embodiment, which also covers the upstream portion 214' of the main guide portion 210 '. This mask 240 'only covers the upper face of the upstream portion 214' but not the opposite face, here the lower face, of the upstream portion 214 'to allow easy fitting of the mask 240' on the downstream portion of the second guide 201. However, it is possible to use an additional mask and reported 270, to hide this opposite face. The mask 240 'may comprise an opening 244' and the upstream portion 214 'may comprise decoupling means, such as prisms and / or ridges (not shown), opposite this opening 244'. These decoupling means are arranged to decouple another portion of the light rays guided in the upstream portion 214 'of the main guide portion 210', so that they exit through this opening 244 '. Thus, an additional luminous halo will be created in the envelope 261 of the vehicle light device 260.
    [0015] In the example illustrated in FIG. 2, this additional luminous halo radiates between the second light guide 201 'and the upper wall of the housing 262. The light sources may be light-emitting diodes 251, 254, also called LEDs or LEDs. . They are arranged vis-à-vis the input dioptres 212, 212 'of the light guides 201 and 201'. They are carried by electronic cards 252, 255, in particular connected to a power supply via connectors 253, 256. The input diopters 212, 212 'can be arranged to reduce the opening angle of the beam of rays. luminous crossing them. For example, they can form a collimator. For example, they may have parabolic portions whose focus passes through the photoemissive element of the corresponding LED 251, 254. FIGS. 3 and 4 illustrate an exemplary embodiment of the junction between the main part and the secondary part of a light guide 1, 101, 201 and 201 'of the light device illustrated in FIGS. 1 and 2. They also make it possible to illustrate the overall shape of the light guides of the light device according to the invention. As previously described, each of the light guides of the light device according to the invention comprises a main light-guiding portion 10, 110 and an attachment portion 20, 120, joining into a junction zone 22, 122. The shape of the sections of these light guides along a longitudinal axis from their input diopter 12, 112, to their main output diopter 18, 118, is similar, and is illustrated in Figure 5. The attachment portion of the light guide 20 , 120, forms a light-guiding secondary portion (the attachment is not shown in Figures 3 to 5).
    [0016] The light guide of FIG. 3 is a plate-shaped light guide, that is to say that its main guide portion 10 comprises upstream portions 14 and 17 flattened downstream. These upstream portions 14 and downstream 17 of the main portion of light guide 10 each comprise two extended faces joined together and defined by a peripheral edge. These extended faces can allow the propagation of light in this main part 10, for example by internal reflection, from the input diopter 12 to the main output diopter 18. These extended faces can be flat, as shown in FIG. 3. The section of these portions in a plane perpendicular to the overall direction of emission of the light beam by the light guide, is generally rectangular. Similarly, the guide secondary portion 20 is plate-shaped, in particular bent. The light guide 101 of FIG. 4 is a rod-shaped light guide, namely that its main guide portion 110 comprises upstream portions 114 and downstream portions 117 in the form of rods. These upstream portions 114 and downstream 117 may allow the propagation of light in this main guide portion 110, for example by internal reflection, from the input diopter 112 to the main output diopter 118. The section of these portions according to FIG. a plane perpendicular to the overall direction of emission of the light beam by the light guide, may for example be generally circular or oblong. Similarly, the guide secondary portion 120 is rod-shaped, in particular curved.
    [0017] In these two embodiments illustrated in FIGS. 3 and 4, the light guides 1 and 101 are intended to receive light rays R1, R2 and Rn, R20 from a light source. These radii R1, R2 and Rn, R20 first pass through an input diopter 12, 112, of the main guiding part 10, 110, and then propagate inside the upstream portion 14, 114, of the main guide portion 10, 110. This upstream portion extends from the input diopter 12, 112, to a reflection portion 16, 116, and to the junction zone 22, 122 of the two parts of 10, 110 and 20, 120. In the alignment of this upstream portion 14, 114, the main guide portion 10, 110 extends downstream of the reflection portion 16, 116 by the downstream portion 17, 117. This The last ends in the main output diopter 18, 118. The reflection portion 16, 116, is formed by an inclined pan forming a narrowing of the main guide portion 10, 110. Thus, as can be seen in Figure 5 , the thickness of the downstream portion 17, 117 is smaller than that of the upstream portion 14, 114. This narrowing is an example of realizat ion for intercepting a second portion of the rays R2, R20, the first portion of rays R1, Rn, being that which is not intercepted.
    [0018] The second portion of rays R2, R20, meeting the reflection portion 16, 116 formed by the narrowing, will be reflected by it in the guide secondary portion 220 to then propagate along the latter.
    [0019] It should be noted that at the junction zone 22, 122, and downstream thereof, the surfaces of the main guide portion 10, 110 and the guide secondary portion, also a portion of the light guide , 20, 120, join in a downstream stop 21, 121. The rays impacting this downstream stop and the immediately surrounding area may have an angle of incidence such that they exit the light guide 1, 101. To reduce this risk, the light guide 1, 101 may have a particular arrangement. As can be seen in FIGS. 3 to 5, the guiding abutment, also a securing part of the lightguide, 20, 120, extends from the junction zone 22, 122, to the 'back. Thus, the extension of the guiding abutment 20, 120 from the main guiding portion 10, 110, begins at this junction area 22, 122, having from this beginning a rearward orientation. Thus, when observed from outside the guide 1, 101, and from the rear thereof, the guide secondary portion 20, 120 forms with the upstream portion 14, 114 of the main guide portion 10, 110, an acute angle (i.e., less than 90 °). On the other hand, when observed from the outside of the guide 1, 101, and from the front thereof, the guide secondary part, also part fixing the light guide, 20, 120, forms with the downstream portion. 17, 117 of the main guide portion 10, 110, an obtuse angle (that is greater than 90 °). For example, when the guide secondary portion 20, 120 is curved, as in these examples, it forms a curve whose rope 24, 124 forms an obtuse angle 13 with said downstream portion 17, 117, seen from outside the guide . This reduces the risk of leakage of certain light rays and increases the chances of reorienting them in the guiding abutment 20, 120. This also allows certain rays R1, Rn, passing next to the reflection portion 16 , 116, and which would impact the area at the downstream edge 21, 121, to be less subject to exit the light guide 1, 101, and continue to propagate in the main guide portion 10, 110, along the downstream portion 17, 117. In addition, this arrangement allows a return back of light rays with the same light guide, and without decoupling (ie without output) of the rays thereof . It should be noted that the guide secondary portion 20, 120 may be arranged in such a way as to use the rays R2, R20, which it guides, in different ways. For example, it may be arranged so that all or part of these spokes R2, R20 propagate to the end 28 of the secondary guiding portion, opposite the junction zone 22, 122, and leave it. , in particular to participate in a signaling function and / or lighting of the road. It may alternatively or cumulatively comprise decoupling means located on its rear and / or front surfaces, these decoupling means being arranged to allow the rays impacting them to leave the guide. When these decoupling means are distributed along the guide secondary portion, also part fixing the light guide, 20, 120, they allow the spokes to exit over the entire extent of its rear surfaces and / or before.
