Description

Title of the invention: LIGHTING DEVICE WITH COUPLED LIGHT GUIDES, FOR A VEHICLE Technical field of the invention

[0001] The invention relates to vehicles comprising at least one lighting device capable of providing a photometric function. State of the art

[0002] Certain vehicles, possibly of the automobile type, include at least one lighting device comprising a source generating photons, a first light guide suitable for receiving the generated photons to deliver them to a first front face, and a second light guide suitable for receiving on a rear face the photons from the first front face to deliver them to a second front face in order to ensure a photometric function.

[0003] It should be noted that this type of lighting device is generally housed in a casing that is part of the latter or of an optical block ensuring one or more photometric functions.

[0004] It should also be noted that this type of lighting device generally ensures a photometric lighting function, such as a daytime running light (or DRL – a photometric signaling function, possibly with variable intensity). But it could also provide a photometric signaling function, such as a turn signal or brake light.

[0005] In some of the lighting devices described above, the second light guide must partially pass through a defined opening in a mask so as to be completely enclosed, and this passage must be made with a predefined minimum gap and flushness with the edge of the mask that delimits this opening. This proves difficult to achieve when the second light guide is flat (or blade-like) and has a small thickness (for example, in the vertical direction), typically less than 10 mm. It should be noted that this proves even more difficult to achieve when the second light guide is curved.

[0006] To obtain these predefined minimum clearances and flushness, the mask is currently attached to a support piece which is either added inside the housing containing the lighting device (which requires dedicated fastening means) or is an integral part of this housing. However, both of the aforementioned arrangements complicate the architecture within the housing, increase the manufacturing cost of the housing and the lighting device or optical unit comprising this housing, and increase the bulk in the latter, which makes it more difficult to assemble the lighting device or optical unit including this housing and therefore increases costs even more.

[0007] The invention therefore aims in particular to improve the situation. Presentation of the invention

[0008] In particular, it proposes for this purpose a lighting device, on the one hand, suitable for equipping a vehicle, and, on the other hand, comprising:

[0009] - a photon source suitable for generating photons,

[0010] - a first light guide suitable for receiving the generated photons in order to deliver them on the front face, and

[0011] - a second light guide adapted to receive photons on a rear face originating from the first front panel to deliver them to a second front panel to ensure a photometric function.

[0012] This lighting device is characterized by the fact that it comprises:

[0013] - a third light guide interposed between the first and second guides light, by being coupled to the rear face of the second light guide and capable of transferring photons delivered to the first front face of the first light guide into the second light guide, and

[0014] - a mask comprising an opening through which the second light guide passes, concealing the third light guide, and aligned with it.

[0015] This alignment of the mask with respect to the third light guide associated with the coupling between the third and second light guides allows that the partial crossing of the opening by the second light guide respects a minimum clearance and a predefined flushness of the edges of the mask, and avoids having to provide a support piece to support the mask.

[0016] The lighting device according to the invention may include other features which may be taken separately or in combination, and in particular:

[0017] - the rear face of the second light guide may include a concave housing open. In this case, its third light guide may include a rear part, comprising another rear face oriented towards the first front face of the first light guide and suitable for receiving the photons delivered on this first front face, and extended by a front part housed in this concave housing in order to transfer into the second light guide photons having entered this rear part;

[0018] - in the presence of the first option, the rear part of the third light guide may include, in a first zone located on a front face, opposite its other rear face and oriented towards the rear face of the second light guide, at least one alignment protrusion. In this case, the mask may include, near a first edge participating in a delimitation of its opening, at least one support protuberance interposed between the second light guide and a corresponding shimming protuberance against which it is shimmed;

[0019] - in the presence of the last sub-option, the rear part of the third guide of light may include an end face defined in a second zone, opposite the first zone with respect to the front part of the third light guide, and bearing against a second edge of the mask, opposite the first edge and participating in the delimitation of the opening, in order to wedge the support protuberance against the corresponding shimming protuberance to immobilize the mask with respect to the second and third light guides;

[0020] - also in the presence of the first option, the other rear face of the rear part the third light guide may include a multiplicity of first three-dimensional elements designed to diffuse the photons delivered on the first front face inside the third light guide;

[0021] - also in the presence of the first option, the front part of the third guide the light guide may include at least a first positioning element designed to cooperate with a second positioning element, corresponding and defined in the concave housing of the second light guide, to position the latter relative to the third light guide;

[0022] - in the presence of the last sub-option, each first positioning element can be arranged in the form of two opposing and semi-truncated conical positioning protrusions, and each second positioning element can be arranged in the form of two opposing, semi-truncated conical recesses suitable for receiving the corresponding positioning protrusions respectively;

[0023] - the first front face of the second light guide may include a multiplicity of second three-dimensional elements capable of scattering photons outwards;

[0024] - its second light guide can be fixedly attached to the third light guide light after housing the front part of the latter in its opening;

[0025] - its third light guide may include at least two mounting tabs suitable for allowing its attachment (for example in a case).

[0026] The invention also proposes an optical block suitable for equipping a vehicle and ensuring at least one photometric function, and comprising a housing containing a lighting device of the type presented above.

[0027] The invention also proposes a vehicle, possibly of the automobile type, comprising at least one lighting device of the type presented above and / or at least one optical unit of the type presented above. Brief description of the figures

[0035] [Fig.7] schematically illustrates, in a perspective view from the rear side, the third light guide of the lighting device of Figures 2 and 3. Detailed description of the invention

[0036] The invention aims in particular to provide a DE lighting device intended to equip a vehicle and having a first light guide GL1 supplying photons to a set of second GL2 and third GL3 coupled light guides, with the third light guide GL3 masked by a mask MD calibrated with respect to the latter (GL3), to ensure a photometric function.

[0037] In what follows, it is considered, by way of non-limiting example, that the lighting device DE is part of an optical unit BO intended to equip the front end of a motor vehicle, and which may optionally perform at least one other photometric function in addition to that performed by the lighting device DE. However, the lighting device DE could be an independent optical component (and therefore constitute an optical unit of a vehicle).

[0038] Furthermore, in what follows, it is considered, by way of non-limiting example, that the optical unit BO (but this could be the lighting device DE) is intended to be fitted to the front end of a motor vehicle, such as a car. But the lighting device DE (or the optical unit BO) can be fitted to any which end, front or rear, of a vehicle (land, sea (or river), or air).

[0039] Finally, in what follows, by way of non-limiting example, the lighting device DE is considered to perform a photometric lighting function. More specifically, it is intended (here) to perform a photometric daytime running light (or DRL) function – a photometric signaling function, possibly with variable intensity. However, it could perform another lighting or signaling function (for example, a brake light or a turn signal).

[0040] In figures 1 to 7, the X direction is intended to be parallel to the longitudinal direction of the vehicle, which is substantially parallel to the lateral (or longitudinal) sides comprising the side doors, the Y direction is intended to be parallel to the transverse direction of the vehicle, which is perpendicular to the longitudinal direction X, and the Z direction is intended to be parallel to the vertical direction of the vehicle, which is perpendicular to the longitudinal direction X and the transverse direction Y.

[0041] In the preceding and following text, the terms "front" and "rear" are defined with respect to the front end of the vehicle. Consequently, the front part of an element is intended to be located closer to the front end of the vehicle than the rear part of that same element.

[0042] Figures 1 to 3 schematically illustrate, at least partially, part of an example embodiment of an optical block BO comprising an example embodiment of a lighting device DE according to the invention and intended (here) to be installed in the front end of a vehicle (here automobile).

[0043] This optical block BO comprises, in addition to the lighting device DE according to the invention, a housing BB in which this lighting device DE is fixedly installed, and a protective glass (not illustrated) located furthest downstream (with respect to the direction of propagation of the photons), fixedly attached to the housing BB and through which exit the photons ensuring the photometric function of at least this lighting device DE.

[0044] As illustrated at least partially in Figures 1 to 3, a lighting device DE, according to the invention, comprises a photon source (not shown), a first light guide GL1, a second light guide GL2, a third light guide GL3 and a mask MD.

[0045] It should be noted that here the lighting device DE does not include a housing because it is intended to be part of an optical unit BO comprising such a housing BB. However, a lighting device DE, according to the invention, may also include a housing and optional protective glass when it constitutes an independent optical unit.

[0046] The photon source is suitable for generating photons to participate in the photometric function (here a daytime running light function).

[0047] For example, this photon source may include at least one light-emitting diode (LED). Alternatively, it could include at least one laser diode or a gas laser, for example. It should also be noted, although not shown in Figures 2 and 3, that the DE lighting device may also include an electronic board comprising the photon source and electronic components and / or circuit(s) for controlling the power supply and operation of this photon source. For example, this electronic board may also be a printed circuit board (PCB).

[0048] The first light guide GL1 is arranged to receive the photons generated by the photon source, for example at at least one of its two opposite ends, to deliver them onto a first front face FV1.

[0049] As illustrated at least partially in Figures 2 to 5, the second light guide GL2 is arranged to receive on a second rear face FR2 the photons which come from the first front face FV1 of the first light guide GL1, and to deliver these received photons on a second front face FV2 in order to ensure the photometric function.

[0050] As illustrated at least partially in Figures 1 to 3, the third light guide GL3 is interposed between the first GL1 and second GL2 light guides by being coupled to the second rear face FR2 of the second light guide GL2. This third light guide GL3 therefore receives photons on a third (or other) rear face FR3 that are delivered to the first front face FV1 of the first light guide GL1. Furthermore, this third light guide GL3 is capable of transferring the photons received on its third rear face FR3 to its third front face FV3 (opposite this third rear face FR3 and coupled to the second rear face FR2 of the second light guide GL2), and then of transferring these photons, having reached its third front face FV3, into the second light guide GL2 (via its second rear face FR2).

[0051] The mask MD includes an opening O through which the second light guide GL2 passes and completely masks the third light guide GL3 (by surrounding the second light guide GL2), so that it (GL3) is invisible from the outside and that the illumination defects it (GL3) induces are also invisible. Furthermore, this mask MD is calibrated with respect to the third light guide GL3, as illustrated in [Fig. 3].

[0052] Some purely illustrative photon paths are shown by one-way arrows in [Fig. 2], in order to illustrate examples of refraction, reflection and propagation of photons between the first front face FV1 and the second front face FV2.

[0053] Thanks to this alignment of the MD mask with respect to the third light guide GL3 (and therefore with respect to the assembly consisting of the third GL3 and second GL2 light guides), the partial crossing of the aperture O by the second light guide GL2 respects a minimum clearance and a predefined flushness of the edges BMI and BM2 of the MD mask which delimit this aperture O, including when the second light guide GL2 is of the flat type (or blade) and has a small thickness (for example along the vertical direction Z), typically less than 10 mm, and / or is curved (as illustrated in figures 1, 2, 4 and 5).Furthermore, the arrangement described above eliminates the need for a support piece to support the MD mask, thus simplifying the architecture within the BB housing, reducing the manufacturing cost of the BB housing and the DE lighting device or BO optical block comprising this BB housing, and reducing the overall size within the latter (BB), which makes the assembly of the DE lighting device or BP optical block comprising the BB housing easier and therefore further reduces costs.

[0054] For example, and as illustrated, without limitation and at least partially, in Figures 1 to 5, the second light guide GL2 can be of the flat (or blade) type and optionally curved. Also, for example, and as illustrated, without limitation and at least partially, in Figures 2, 3, 6 and 7, the third light guide GL3 can also be of the flat (or blade) type and optionally curved (in which case the first light guide GL1 is also preferably curved).

[0055] Also, for example, and as illustrated, without limitation and at least partially, in Figures 2, 3, and 5, the second rear face FR2 of the second light guide GL2 may include a concave housing LC that is open (here towards the rear and therefore towards the third light guide GL3). In this case, the third light guide GL3 may include rear portions PR and front portions PV that extend each other. The rear portion PR includes the third (or other) rear face FR3, which is oriented towards the first front face FV1 and is adapted to receive the photons delivered to the first front face FV1. The front portion PV extends forward from the rear portion PR and is housed in the concave housing LC of the second light guide GL2 in order to transfer into the latter (GL2) photons that have entered the rear portion PR.In other words, the front PV part is embedded in the second GL2 light guide at its concave LC housing, as illustrated in Figures 2 and 3.

[0056] This arrangement allows for a "deep" and almost omnidirectional diffusion of photons in the second light guide GL2, which promotes their distribution in the latter (GL2) and therefore the homogeneity of the lighting at the level of the second front face FV2.

[0057] But other types of coupling between the third GL3 and second GL2 light guides can be envisaged.

[0058] Also, for example, and as illustrated, without limitation and at least partially, in Figures 2 to 4 and 6, in the presence of the recessed arrangement, the rear portion PR of the third light guide GL3 may include a first zone ZI located on its third front face FV3 (opposite its third rear face FR3 and oriented towards the second rear face FR2 of the second light guide GL2), and comprising at least one mounting protrusion PRC. It should be noted that in the example illustrated, without limitation, the first zone ZI is located in the upper part of the rear portion PR, which is situated above the front portion PV, because the second light guide GL2 extends substantially horizontally (along the transverse direction Y).However, in unillustrated alternative embodiments, the first zone ZI could be located in the lower part of the rear part PR (below the front part PV), or to the right or left of the front part PV when the second light guide GL2 extends substantially vertically (along the vertical direction Z).

[0059] In this case, as illustrated, but not limited to, and at least partially, in [Fig. 3], the MD mask may include at least one support protrusion PRA near its first edge BMI (here upper and participating in the delimitation of the aperture O (here in its upper part)). Each support protrusion PRA is interposed between the second light guide GL2 (and more precisely here its upper face (GL2)) and the corresponding alignment protrusion PRC against which it (PA) is aligned.

[0060] Here, each PRC shimming protrusion protrudes (or projects) forward (substantially along the longitudinal direction X) from the third front face FV3 of the third GL3 light guide, and each PRA support protrusion protrudes (or projects) backward (substantially along the longitudinal direction X) from the first (upper) BMI edge of the MD mask.

[0061] It should be noted that in the example illustrated, but not limited to, in [Fig. 4], the first zone ZI (of the rear part PR of the third light guide GL3) comprises three alignment protrusions PRC (here substantially aligned along the transverse direction Y due to the illustrated arrangement), onto which three support protrusions PRA are respectively aligned. However, the number of alignment protrusions PRC, like the number of support protrusions PRA, can take any value greater than or equal to one.

[0062] It will be understood that this calibration makes it possible to guarantee compliance with the predefined minimum clearance and flushness of the first BMI edge (here upper) of the MD mask in relation to the second GL2 light guide.

[0063] Thanks to the presence of the MD mask downstream of the third front face FV3 of the rear part PR of the third light guide GL3, the light intensity defects caused by the PRC shimming protuberance(s) and PRA support protuberance(s) are invisible from the outside.

[0064] Also, for example, and as illustrated non-limitingly and at least partially in Figures 2 and 3, the rear part PR of the third light guide GL3 can also include a second zone Z2, opposite its first zone ZI with respect to the front part PV (and therefore here lower), having an end face FE which rests against the second edge BM2 (here lower) of the mask MD, opposite the first edge BMI and participating with the latter (BMI) in the delimitation of the aperture O. This makes it possible to wedge the (each) support protuberance PRA against the corresponding shimming protuberance PRC in order to immobilize the mask MD with respect to the second GL2 and third GL3 light guides.It will be understood that by translating (relatively) the MD mask towards the third front face FV3 of the third light guide GL3, the second edge BM2 of the MD mask begins to press against the end face FE (here lower), which progressively pushes the first edge BMI of the MD mask towards each PRC alignment protrusion (and therefore upwards here), until each PRC alignment protrusion is pressed against the corresponding PRA support protrusion and thus immobilizes the MD mask relative to the second GL2 and third GL3 light guides.

[0065] It will be noted that in order to facilitate the relative movement of the end face FE against the second edge BM2 (lower) of the mask MD, the latter (BM2) can be projected backwards over a certain distance, preferably with a slight inclination with respect to (here) a horizontal plane XY, as illustrated non-limitingly in figures 2 and 3.

[0066] Also, for example, and as illustrated, without limitation and at least partially, in Figures 2, 3, and 5, the third rear face FR3 of the third light guide GL3 may comprise a multitude of first three-dimensional (or 3D) elements ET1 which are adapted to diffuse within the third light guide GL3 the photons delivered on the first front face FV1. These first three-dimensional elements ET1 advantageously facilitate the distribution of incoming photons within the third light guide GL3. For example, these first three-dimensional elements ET1 may be arranged in the form of inclined facets or micro-facets of different orientations.

[0067] Also, for example, and as illustrated, without limitation and at least partially, in Figures 5 and 7, the front portion PV of the third light guide GL3 and the concave housing LC may respectively comprise at least one first positioning element EPI and at least one corresponding second positioning element EP2. These first EPI and second EP2 positioning elements are designed to cooperate together in order to position (precisely) the second light guide GL2 relative to the third light guide GL3. This ensures that the second light guide GL2 is positioned in the aperture O with the predefined minimum clearance and flushness of the first BMI and second BM2 edges of the mask MD relative to the second light guide GL2.

[0068] Also, for example, and as illustrated, without limitation and at least partially, in Figures 4 and 7, each first positioning element EPI can be arranged in the form of two opposing, semi-truncated conical positioning protrusions (here, upper and lower), and each second positioning element EP2 can be arranged in the form of two opposing, semi-truncated conical recesses (here, upper and lower) adapted to receive the corresponding EPI positioning protrusions. Each first positioning element EPI thus fits inside a corresponding second positioning element EP2.

[0069] It will be noted that in the example illustrated non-limitingly in Figures 4 and 7 the front part PV of the third light guide GL3 comprises six first positioning elements EPI cooperating with six second positioning elements EP2 of the aperture O. But the number of first positioning elements EPI, like the number of second positioning elements EP2, can take any value greater than or equal to one (and preferably two).

[0070] It will be noted that instead of using first EPI and second EP2 positioning elements acting by cooperation of form, one could use first EPI and second EP2 positioning elements arranged in the form of clipping means, for example.

[0071] It should also be noted that the second light guide GL2 can be permanently attached to the third light guide GL3 after the front PV portion of the latter (GL3) has been housed in its concave LC housing, and the possible first and second EP2 positioning elements can be used together. For example, this permanent attachment can be achieved by welding or bonding.

[0072] Also, for example, and as illustrated non-limitingly and at least partially in Figures 2 to 4, the first front face FV1 of the second light guide GL2 may comprise a multiplicity of second three-dimensional (or 3D) elements ET2 which are suitable for scattering photons outwards. This allows to strengthen the homogeneity of the lighting around the second light guide GL2 (outer side, i.e. downstream of the MD mask).

[0073] For example, these second three-dimensional elements ET2 can be arranged in the form of micro-facets of different orientations.

[0074] Also, for example, and as illustrated non-limitingly and at least partially in [Fig.2], the first rear face FRI of the first light guide GL1 may comprise a multiplicity of third three-dimensional (or 3D) elements ET3 which are suitable for reflecting (by internal reflections) the photons, which propagate inside the first light guide GL1, towards its first front face FV1.

[0075] For example, these third three-dimensional elements ET3 can be arranged in the form of inclined facets or micro-facets of different orientations.

[0076] Also, for example, and as illustrated, without limitation and at least partially, in Figures 6 and 7, the third light guide GL3 may include at least two mounting tabs PF suitable for attaching it, for example, to an internal wall of the BB housing. This attachment may, for example, be achieved by screwing. But it could also be achieved by clipping or gluing.

[0077] Also, for example, the first GL1, second GL2, and third GL3 light guides can be one-piece parts made by molding a rigid material that is transparent to the photons generated by the photon source. For example, this material can be polycarbonate (or PC), and possibly, at least in the case of the second GL2 and third GL3 light guides, a "TARFLON" PC (registered trademark), since the latter promotes the scattering of photons.
