Description

[Technical Field]

[0001] The present invention relates to the field of lighting, including and related to signal transmission, particularly optical components. It is applicable to the field of motor vehicles. In particular, it relates to lighting devices incorporating multiple modules whose light sources are arranged in the same carrier plane.

[0002] One potential end use is the generation of low beams that normally illuminate the road ahead of a motorized vehicle. Such generation may be combined with the generation of other beams, particularly complementary high beams. Summary of the Invention

[0003] prior art In the automotive sector, devices are known that emit a light beam that performs or participates in the performance of lighting and / or signaling functions.

[0004] To comply with current regulations, these devices must emit light in desired locations while limiting light levels in certain areas.

[0005] These lighting devices or headlights allow a light beam to be generated. One example of a light beam is a low beam or dipped beam, i.e., a light beam with a cutoff used primarily for illumination purposes at night, with a range on the road of approximately 70 meters and an illuminating distribution such that drivers of oncoming vehicles are not subjected to unpleasant glare. Typically, this beam has a cutoff at its upper part, which has a horizontal segment, preferably about 0.57 degrees below the horizon, and a segment with an angle called a kink, so as not to illuminate the zone where drivers of oncoming vehicles are likely to be located. The lighting device may also generate a high beam or a complementary high beam, which, in combination with the low beam, allows for the formation of a high beam.

[0006] It is known practice to generate these light beams using a plurality of light-emitting modules. One such light-emitting module conventionally comprises a concentrator having a reflecting surface of a surface of revolution with a shell-shaped profile in a half-space defined by a horizontal plane. A substantially point light source of the light-emitting diode type is located at a first focus on the reflecting surface and shines light into the half-space in the direction of said surface. The light rays are thus reflected so as to converge towards a projection lens. In this regard, Japanese Patent Publication FR3118120A1 discloses a light-emitting device comprising a plurality of light-emitting modules supported on a plate, which provides a stylistic effect (which may be required depending on the shape of the vehicle body at the position of the headlamp where the light-emitting device is installed) in which, when the vehicle is observed from the front, the beams emitted by the various modules from their projection lenses form a profile that slopes from a first end forming a low, forward point of the profile (further forward of the vehicle) to a second end forming a high, rearward point of the profile (closer to the rear of the vehicle). To achieve this, various modules are supported on a common plate, and the modules are arranged side by side along a profile, allowing the device to extend from near the front of the motor vehicle toward the rear. Furthermore, in order for the profile to extend from a low point to a high point, the plate is mounted tilted at a non-zero angle relative to a horizontal line parallel to the optical axis. This arrangement results in all modules being tilted relative to the desired optical axis of projection (which is usually horizontal and oriented toward the front of the vehicle), which entails a high degree of complexity in the layout of the elements involved in the projection; in particular, in the embodiment shown in Figure 5 of this prior art document, the tilt of the plate, light source, and collector requires the use of a prismatic projection lens, which leads to losses and chromatic aberrations. Furthermore, with regard to the prismatic design of the lens, this technology quickly approaches its limits when large tilts are desired in the profile formed by the modules.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device that makes it possible to at least partially overcome the above-mentioned drawbacks.

[0008] Other objects, features and advantages of the present invention will become apparent from a consideration of the following description and accompanying drawings, and it will be understood that other advantages may be incorporated.

[0009] overview To this end, according to one embodiment, there is provided a light emitting device configured to project an output light beam along an optical axis of projection.

[0010] It is intended to be oriented horizontally from the rear to the front of the vehicle in the functional position of the device on the vehicle, in which the device is positioned on one side of the front of the vehicle with the aim of projecting towards the front of the vehicle.

[0011] The apparatus includes: - a plurality of light emitting modules arranged side by side, each including at least one light source, one concentrator having a reflective surface, and one projection lens, the reflective surface being configured to reflect light rays generated by the light source towards the projection lens; a carrier in which all light sources are arranged in a carrier plane, the carrier plane making an angle γ with the horizontal plane about a tilt axis Y that is horizontal and perpendicular to the optical axis of the projection, and an angle φ with the horizontal plane about the optical axis of the projection.

[0012] The device further comprises: - the projection lens of each light-emitting module has a lens optical axis parallel to the optical axis of the projection; - the reflective surface of each concentrator is configured such that reflected light rays form a light beam directed in a primary direction of reflection that is coincident with the lens optical axis; - the light sources are arranged on the carrier in an arrangement with a first offset along the optical axis of projection and a second offset in the vertical direction Z when the device is in the functional position; - at least one of the angle γ and the angle φ is non-zero, the angle γ being included in a first angular sector that enables the main direction of light emission of the light source in the functional position to be directed towards the front of the vehicle, and the angle φ being oriented in a second angular sector that enables the main direction of light emission of the light source in the functional position to be directed towards the interior of the vehicle.

[0013] All light sources of the device can therefore be located on a single carrier, which may typically be a single plate that can take the form of a printed circuit board (although the device can be integrated into more complex systems including other light-emitting modules on other carriers, in particular to generate light beams that perform other vehicle lighting functions). Even if only one carrier is used, the light reflected by the collector is still now directed along the optical axis of the projection lens. This facilitates the beam projection stage.

[0014] Preferably, the lens is symmetrical about the lens optical axis.

[0015] In order to direct the light from the reflector along the optical axis of the lens, the invention overcomes the prejudice that the collector and its light source must form a permanent assembly, i.e., their relative position is necessarily fixed, so that the tilt of the collector is the same as the tilt of the light source (determined by the tilt of the carrier). In contrast, the collector here is advantageously positioned independently of the position of the carrier, which makes it possible to direct its main direction of reflection along the optical axis of the projection lens. This therefore makes it possible to avoid using a prismatic lens as the projection lens.

[0016] Another aspect relates to a vehicle having two light emitting devices, each located on one side of the vehicle and adapted to project a light beam towards the front of the vehicle.

[0017] The two devices are preferably symmetrical with respect to a central vertical plane of the vehicle parallel to the optical axis. [Brief explanation of the drawings]

[0020] Detailed Description Before commencing a detailed discussion of embodiments of the invention, optional features that may be used in combination or alternatively are outlined below: - The first angle sector is 0°~12°; - the second angular sector is between 0° and 6°, preferably between 0° and 3°; - for each light emitting module 2, the projection lens 23 is symmetrical with respect to its optical axis; the light source 21 is arranged on the carrier such that, when the device is in the functional position, the first offset progresses monotonically along the projection optical axis 5 and the second offset progresses monotonically in the vertical direction Z; the light source 21 forms a profile P in the carrier plane 4, which, in the functional position, is directed towards the rear of the vehicle 0 when the profile P is directed towards the outside of the vehicle 0; - the profile P forms a first projection in the vertical direction Z in the plane formed by the optical axis 5 of projection and the tilt axis Y, said first projection having a first tilt β with respect to the tilt axis Y, said first tilt β being less than 50°, preferably less than 35°; - the profile P forms a second projection along the optical axis of projection 5 in the plane formed by the vertical direction Z and the tilt axis Y, said second projection having a second tilt α relative to the tilt axis Y, said second tilt α being less than 10°, preferably less than 5°; - for each light emitting module 2, the reflecting surface 221 has a rear edge 222, and the focal point of the projection lens 23 is located near said rear edge 222, preferably at a distance of less than 10 mm; The device is configured to generate an output light beam of the low beam type.

[0021] In the following description, terms related to vertical, horizontal, or lateral (or sideways) directions are to be understood as referring to the position where the module is intended to be installed in the vehicle. The terms "vertical" and "horizontal" are used in this description to mean a direction perpendicular to a horizontal plane (corresponding to the altitude of the system) for the "vertical" term, and a direction parallel to the horizontal plane for the "horizontal" term. These directions are to be considered under the conditions of operation of the device in the vehicle. The use of these terms does not imply that slight variations in the vertical and horizontal directions are outside the scope of the invention. For example, here, a tilt of ±10° relative to these directions is considered a minor variation relative to the two preferred directions. With respect to the horizontal plane, the tilt is generally between -5° and 4°, while in the lateral direction it is between -6° and 7.5°. Two directions are considered to be coincident or parallel if there is no significant angular deviation from the standpoint of operation or manufacturing tolerances; in particular, an angular deviation of 5° or less may be appropriate. Furthermore, the adjectives "below" and "above" are to be considered in relation to the vertical; in a given context, an upper element will be positioned vertically above (but not necessarily touching or vertically aligned with) a lower element.

[0022] In the illustration, an XYZ Cartesian coordinate system is used as reference: the X axis is horizontal and points from the front to the rear of the vehicle; the Y axis is a horizontal axis that intersects the X axis; and the Z axis is vertical.

[0023] 1A and 1B show in perspective a front segment of a vehicle 0, which is provided with an optical unit 1 capable of receiving a lighting device according to the invention.

[0024] The X axis corresponds to the longitudinal direction of the vehicle, the Y axis corresponds to the width of the vehicle (in this case horizontal and perpendicular to the longitudinal direction) and the Z axis corresponds to the vertical direction (in which the height of the vehicle is measured). Typically, the projection optical axis 5 of the beam resulting from the projection of the module is oriented along the X axis and is pointed in the opposite direction, i.e. from the rear to the front of the vehicle.

[0025] As can be seen, the lighting device is arranged at the front of the vehicle 0 on the left side (in the direction of forward movement of the vehicle), with a symmetrical lighting device being arranged on the right side of the vehicle. A profile P of the arrangement of the modules of the lighting device is shown; it is preferably linear; in FIG. 1A this profile P forms a second projection along the projection optical axis 5 in the plane formed by the vertical direction Z and the tilt axis Y, said second projection having a second tilt α relative to the tilt axis Y, said second tilt α being less than 10°, preferably less than 5°. In this way, the arrangement of the light-emitting modules 2 has a tilt α when viewed from the front, which in this case is upwards when considering a movement along the lighting device in the direction of the corresponding lateral part of the vehicle 0.

[0026] 1B, the profile P forms a first projection in the vertical direction Z in the plane formed by the projection optical axis 5 and the tilt axis Y, said first projection having a first inclination β relative to the tilt axis Y, which inclination β is less than 50°, preferably less than 35°. The lighting device thus has an inclination β when viewed from above, which in this case is directed towards the rear of the vehicle when considering a movement along the lighting device in the direction of the corresponding lateral part of the vehicle 0.

[0027] The tilt due to angle α and / or angle β may be determined primarily by the shape of the vehicle body and requires a specific arrangement of the light-emitting modules, as described below. Thus, profile P does not necessarily have to be perfectly linear; it may, for example, have curvature, and it is desirable that the changes in angle α and angle β are monotonic, i.e., their derivatives do not change sign.

[0028] 12 shows a schematic representation of the front of the vehicle 0 in the first embodiment and the general orientation of the plane 4 corresponding to the surface of the carrier that supports the light sources of the various modules described below. It is noted that in this particular case, the plane 4 is inclined relative to the normal to the outside of the vehicle, at an angle γ between the X axis and the carrier plane 4.

[0029] 2 to 8 provide details of an embodiment of a light emitting device according to the invention in this first embodiment.

[0030] FIG. 2 thus provides a plan view of an apparatus comprising multiple modules 2. Each module 2 allows for the formation of a module beam, and these various beams can be projected to generate the output beam of the light-emitting device. One or more modules 2 may be configured to generate a diffuse fundamental beam in the form of a low-power beam; one or more other modules 2 may be configured to generate a beam including a cutoff with a kink toward the center to complement the fundamental beam with the low-power beam. For example, the paired modules 2 in FIG. 2 may be used to form the flat of a low-beam headlight (i.e., a flat segment projected below the horizon); complementary, at least one of the other modules shown forms a kink that forms the cutoff of this low beam; in this case, the profile of the rear edge 222 of the concentrator 22, described in detail below, is designed to give this cutoff its shape.

[0031] Optionally, one or more other modules 2 may be configured to form a supplementary beam for the high beam function, the supplementary beam not including a cutoff and providing emission above the horizon.

[0032] According to one possibility, module 2 is selectively activatable to generate an adaptive output beam.

[0033] Each light-emitting module 2 includes at least one light source 21, which may typically be a light-emitting diode. As particularly shown in Figure 4, the light source 21 preferably has a light-emitting surface 211 opposite a bottom surface attached to the carrier plane. Typically, all light sources 21 are supported by a single carrier, such as a plate, which may be realized by a printed circuit board.

[0034] The light sources 21 are spaced along the carrier in such a way as to form the profile P shown above. Figure 2 provides an example of a juxtaposition of the modules 2 with a gradual offset of the positions of the light sources 21 in the XY plane (which is preferably monotonic, i.e. the offset is always in the same direction, towards the rear of the vehicle, in particular when considering the lateral movement of the vehicle). This gradual offset defines the profile P. The latter is preferably linear. According to one option, the light sources 21 are perfectly aligned along the profile P. However, for construction reasons, there may be an offset between the position of the light sources 21 and the profile P. In this case, the profile P may be a straight line corresponding to a linear regression of the positions of the light sources 21. Alternatively or additionally, the profile P may be defined as a central straight line located at a distance of no more than 3 mm from each of the light sources 21. Each light-emitting module 2 further comprises a collector 22. The latter is advantageously shell-shaped, the concave surface of which has a reflecting surface arranged towards the light source. The collector 22 has an edge surface 223, the rear part of which, i.e. the part oriented in the X direction towards the rear of the vehicle, forms the rear edge 222 of the collector 22. Preferably, the reflecting surface 221 has a parabolic profile defined by a generatrix, with its focal point located at the associated light source 21. The focal length of the reflecting surface 221 may be 3 mm. The distance between the rear edge 222 and the centre of the exit face of the projection lens 23 may be 65 mm.

[0035] It will be appreciated that the light emitted by the light source 21 is directed onto a reflective surface of a collector 22 associated with the light source 21 so as to produce a reflected light ray in the form of a beam. Preferably, this reflected beam has a direction corresponding to the direction of the generatrix of the reflective surface.

[0036] Each module 2 further comprises a projection lens 23. As shown in FIG. 2, the various lenses 23 may be supported by a common carrier 3. Preferably, the exit refractive interfaces of the lenses 23 form a continuous surface. The lenses preferably each form a rectangular element. However, it is not essential that the active portion of the lens 23 covers the entire surface of this rectangular element; rather, the active portion may be limited to a window, preferably a rectangular window, whose arrangement is adjusted to form a projection axis directed in the main direction of reflection of the corresponding collector. A given module 2 may include multiple collectors, preferably one associated light source for each collector, as is the case for the three modules in FIG. 2. Furthermore, the lenses may be integrally formed from a single material.

[0037] The projection lens 23 of each module 2 may be made from an optical polymer; it may be polymethylmethacrylate (PMMA) or polycarbonate. Preferably, the lens is symmetrical about the optical axis, at least in the plane corresponding to the height of the lens.

[0038] Additionally, FIG. 2 shows a separator 24 extending between the concentrator 22 and the lens 23 to optically isolate at least some of the modules.

[0039] 3 provides another illustration of the first embodiment of the invention, this time as seen from the front. Note the angular offset α between the profile P and the direction of the Y axis. Note also here that, as in the top view, the modules 2 are juxtaposed such that their offset progresses monotonically in the vertical direction. In particular, the closer the modules 2 are to the sides of the vehicle 0, the higher they are.

[0040] Preferably, the lens 23 follows the tilt of the profile P. In contrast, this tilt is not necessary for the collector 22. In the first embodiment, the plane of symmetry of the collector 22 is preferably oriented along the normal to the emission surface 211 of the corresponding light source 21.

[0041] Figure 4 shows another illustration of the first embodiment of the invention in the XZ plane. Note that the carrier plane 4 is at an angle γ with respect to the horizontal. This makes it possible to move the profile P across the carrier plane 4 to achieve the desired angles α and β. Figure 4 also shows that despite the tilt of the carrier 4 by the angle γ, the generatrices of the profile of the concentrator 22 remain horizontal along the X axis. The edge surface 223 of the concentrator 22 is horizontal.

[0042] FIG. 5 is a perspective view showing the resulting configuration of the optical module of the device, where the light source is supported in a carrier plane 4 which is itself inclined with respect to the horizontal plane.

[0043] FIG. 6 provides an example of the path of the light rays generated by the light source 21 in this first embodiment, with a cross section in a plane oriented in XZ.

[0044] In particular, the paths of the various light rays are shown, with reflection from the collector 22. Light rays 25 emerging from the collector 22 are directed towards the projection lens 23. Advantageously, the collector 22 is configured such that the main direction of reflection corresponds to the optical axis of the lens 23, which itself corresponds to the projection optical axis 5 shown in Figure 6. It can be seen that tilts of the carrier plane 4, and therefore of the light source 21, are not followed by the collector 22, whose projection is directed overall along the optical axis of the lens.

[0045] In this way, the output of the collector 22 is a beam that is correctly directed with respect to the target of projection of the output beam. In particular, this allows a non-prismatic lens to be used. Preferably, it may be a lens 23 that is at least symmetric about a horizontal plane containing the optical axis 5, as shown in Figure 6.

[0046] To optimize this result and obtain the proper direction for the beam reflected by collector 22, it is advantageous to ensure that the first focal point of lens 23 is located near the rear edge 222 of collector 22. Preferably, the maximum distance separating the focal point of lens 23 from the rear end portion of collector 22 is 10 mm.

[0047] Figure 7 shows an example of the determination of the tilt angle of the carrier plane 4 relative to the horizontal plane in the case of a rotation about the Y axis, corresponding to the angle γ shown in Figure 4, for the first embodiment, and illustrated by a PCBT curve plotting the angles β and α with respect to the value of the angle γ. Recourse to such a diagram can also be made, mutatis mutandis, for the other two embodiments described below.

[0048] The angles β and α are not zero. Preferably, the angle β is selected between 0° (exclusive) and 50° (inclusive); more preferably, it is equal to or less than 35°. Preferably, the angle α is selected between 0° (exclusive) and 10° (inclusive); more preferably, it is equal to or less than 5°.

[0049] In general, for the first embodiment and for the other embodiments described below, it is preferred that the angle γ is between 0° (excluding the end-point values ​​when the angle φ is zero as described below, but including the end-point values ​​when the angle φ is non-zero as described below) and 12° (including the end-point values).

[0050] Figure 8 provides a representative example of the isocandela curves of the projection generated by the proposed light-emitting device to form a low-beam output beam. The flatness of the beam on the cut-off line can be clearly seen, with a concentration of intensity near the optical axis.

[0051] In the second embodiment, the carrier plane 4 is tilted so that it rotates about the X axis instead of the Y axis of the first embodiment.

[0052] An example of a front view representation of this second embodiment is given in Figure 9. As before, the modules 2, each including at least one light source 21, one collector 22 and one projection lens 23, are arranged so as to be juxtaposed along a profile P in a plane 4. The explanations given above regarding the details concerning the modules 22 and their relative arrangement are fully applicable to this second embodiment. The difference lies in the orientation of the plane 4. Figure 11 shows this difference schematically in comparison with the first embodiment shown in Figure 12.

[0053] In Figure 11, the carrier plane 4 is oriented at an angle φ to the Y axis in the vertical YZ plane. Note that this angle is configured so that the plane 4 gradually rises towards the side of the vehicle. As in the previous embodiment, it is advantageous that the arrangement of the plane 4, and more preferably the arrangement of the entire device, is typically the same for the two light-emitting devices in the optical unit 1 shown in Figures 11 and 12, each located on a different side of the front of the vehicle 0.

[0054] Thus, in the second embodiment with inclination φ, the carrier planes 4 of the two light-emitting devices mounted on the vehicle 0 form part of the stroke of a "V", the junction of which is located in the mid-plane of the vehicle oriented along the XZ plane.

[0055] Returning to FIG. 9 , it is noted that, as mentioned above, the light source 21 is supported by a flat surface 4 and therefore has an emission surface whose normal is inclined with respect to the Z-axis. In this situation, the tilt φ directly determines the angle α, which is equal to it. Preferably, the collectors 22 do not have this tilt and remain oriented so that their generatrices are parallel to the X-axis; preferably, their edge surfaces 223 remain positioned in a plane parallel to the XY plane. In this way, the beam reflected by the reflective surface of the collector 22 is projected with a satisfactory light distribution around the optical axis 5 of the projection lens 23. As before, it is advantageous for the rear edge 222 of the reflective surface 221 of the collector 22 to substantially coincide with one of the foci of the projection lens 23. The proximity parameters given above with reference to the first embodiment are also applicable to the second embodiment.

[0056] Preferably, the angle φ is selected between 0° (excluding the end-point values ​​when the angle γ is zero; including the end-point values ​​when the angle γ is non-zero) and 6° (including the end-point values); more preferably, it is selected to be equal to or less than 3°.

[0057] It will be clear that the tilt γ and the tilt φ can be combined, as indicated in the preceding paragraphs. Figure 10 shows this embodiment together with the plane 4 in which this double tilt is provided. The relative positions of the elements of each module 2 shown for the two preceding embodiments apply in combination in this third embodiment. The explanations given above regarding suitable configurations for the tilts (φ and γ respectively) can therefore be relevantly implemented in this third embodiment.

[0058] In use, in all embodiments, one or more light emitting modules 2 can be activated, preferably selectively, so that each generates a module beam that results in an overall output beam that is projected towards the front of the vehicle 0 in the direction of the optical axis 5. The planar tilt and the adaptation of the relative positions between the various components, in particular between the light source, collector and lens, inventively ensure a uniform and optimized beam projection in the direction of the optical axis, in particular by reducing aberrations.

[0059] The invention is not limited to the above-described embodiments.
