Description

[Technical Field]

[0001] The present invention relates to the field of lighting, and more particularly to lighting for motor vehicles. [Background technology]

[0002] Patent document 1 (WO 2020 / 025171 A1) discloses a lighting module for a motor vehicle, comprising a light source, a concentrator with a reflective surface in the form of a cover positioned facing the light source, and a projection lens configured to image the reflective surface illuminated by the light source. For this purpose, the projection lens has a focal point positioned on the reflective surface close to its trailing edge, so as to form a sharp horizontal cutoff by imaging the trailing edge. This document also discloses a lighting module with multiple sub-modules (such as those described below) positioned side-by-side and combined with each other to form a cutoff light beam. This lighting module is advantageous in that it allows multiple sub-beams to be combined with a common projection lens. However, the horizontal space available for headlamps in certain vehicle configurations does not allow this type of lighting module to be used. In fact, in certain vehicle configurations, the space available vertically, or nearly vertical but tilted relative to the vertical, is greater than the horizontal space.

[0007] According to an advantageous embodiment of the invention, the plane mirrors in the first and second optical devices are each parallel to the axis of tilt.

[0008] According to an advantageous embodiment of the invention, each of the plane mirrors of the first and second optical devices has an inclination angle β relative to a direction perpendicular to the plane of the plate, the angle β being advantageously greater than 0° and / or less than 60°.

[0009] According to an advantageous embodiment of the invention, the lenses of the first and second optical devices extend in a main direction inclined at an angle γ to the vertical, the angle γ being advantageously greater than 0° and / or less than 45°.

[0010] According to an advantageous form of the invention, the lenses in the first and second optical devices are aligned adjacent to each other.

[0011] According to an advantageous embodiment of the invention, the angle α of inclination of the plates is greater than 0° and less than 90°. Advantageously, the angle α is greater than 0° and / or less than 90°. Even more advantageously, the angle α is greater than 20°.

[0012] According to an advantageous embodiment of the invention, each of the first and second optical devices is configured to image an area of at least one reflective surface of the corresponding first or second collector, said area being located rearward of at least one light source of said first or second collector, "rearward" meaning in the main direction of propagation of the corresponding first or second reflected light beam.

[0013] According to an advantageous embodiment of the invention, at least one of the first and second incident light beams has an upper horizontal cut-off.

[0014] According to an advantageous embodiment of the invention, at least one light source of the first and second light motors is arranged in the same plane on the plate, and advantageously at least one light source of the first and second light motors is arranged on the front surface of the plate.

[0015] According to an advantageous embodiment of the invention, each of the at least one reflecting surface of the first and second collectors has the shape of a cover with an elliptical or parabolic profile facing towards a corresponding one of the at least one light source of the first and second light motors.

[0016] According to an advantageous embodiment of the invention, the lighting module comprises a third sub-module comprising: a third light motor positioned on the plate behind or in front of one of the first and second light motors with respect to the projection of the optical axis onto the plate, the third light motor comprising at least one light source and a third concentrator, the third concentrator having at least one reflective surface capable of reflecting light rays emitted by the at least one light source of the third light motor as a third reflected light beam; and a third optical device capable of projecting the third reflected light beam as a third projected light beam, the third optical device comprising a projection lens and a plane mirror capable of returning the third reflected light beam towards the projection lens of the third optical device.

[0017] According to an advantageous form of the invention, the first, second and third light motors are aligned in a main direction corresponding to the projection of the optical axis onto the plate.

[0020] According to the present invention, the light source may be a light emitting diode (also known as an LED).

[0021] The solution according to the invention is advantageous in that it makes it possible to produce a high-performance lighting module with limited horizontal or lateral dimensions. The use of a common plate for the different light motors is particularly advantageous in that it simplifies the construction and assembly of the lighting module. Furthermore, the ability to align the projection lenses with a main direction is particularly advantageous for the integration of the lighting module into the overall shape of the motor vehicle. This main direction can be inclined rearward and / or laterally with respect to the vertical. This is also particularly advantageous for the integration of the lighting module into the overall shape of the motor vehicle.

[0022] At least two of the projection lenses (in particular one of the first projection device and one of the second projection device) can be integrated into a single piece, which is particularly advantageous for assembly, especially when the projection lenses are aligned in a main direction (a direction that, when projected onto the plate, is approximately parallel to the main direction of alignment of the collectors on the plate).

[0023] The side of the plate supporting the collector and light source can face forward in the direction of light beam emission by the module. Similarly, each projection lens, whether assembled as a single piece or not, can be positioned in front of the plate with its light entrance surface facing towards the plate and its light exit surface facing forward.

[0024] Another subject of the invention in general is a headlamp for a motor vehicle comprising a lighting module according to the invention. In particular, the headlamp can comprise a housing, which is closed by a closure wall, in which the lighting module is arranged inside the housing and through which the projected light beam is emitted.

[0026] In the following description, orientations indicated by relative terms such as "vertical," "horizontal," "longitudinal" (including feminine and plural forms), "up," "down," "front," and "rear" refer to the orientation of the lighting module(s) when assembled and operational on a motor vehicle, as shown in the figures.

[0027] 1 to 3 show a lighting module according to a first embodiment of the present invention.

[0028] FIG. 1 includes a perspective view and a front view of a lighting module according to a first embodiment of the present invention.

[0029] FIG. 2 is a side view of the lighting module of FIG.

[0030] The following description will be given in combination with FIG. 1 and FIG.

[0031] The illumination module 2 includes a first illumination sub-module 4, which essentially consists of a first light motor 6 and first optical devices 12 and 14. The first light motor 6 is configured to produce a first reflected light beam. The first optical devices 12 and 14 are configured to project the first reflected light beam as a first projected light beam.

[0032] The first light motor 6 comprises light sources 8.1, 8.2, and 8.3 and a light collector 10 provided with reflective surfaces 10.1, 10.2, and 10.3 arranged side by side. The reflective surfaces 10.1, 10.2, and 10.3 form a cavity that opens toward the corresponding one of the light sources 8.1, 8.2, and 8.3, respectively. Advantageously, a specific light source is associated with each reflective surface. In this case, reflective surface 10.1 faces light source 8.1, reflective surface 10.2 faces light source 8.2, and reflective surface 10.3 faces light source 8.3. It should be understood that the number of light source / reflective surface pairs can be different from three and can be one, two, four, or even five or more. The light sources 8.1, 8.2 and 8.3 are of the light-emitting diode type and each illuminates a space defined by a plane in a main direction perpendicular to said plane. The light rays emitted by the light sources 8.1, 8.2 and 8.3 are collected and reflected by the reflecting surfaces 10.1, 10.2 and 10.3 towards the first optical devices 12 and 14.

[0033] The first optical device comprises a plane mirror 12 and a projection lens 14. The plane mirror 12 is positioned facing the first light motor 6 so as to receive the light rays of the first light motor 6 and reflect them towards the projection lens 14. The flatness of the plane mirror 12 has the effect of not optically altering the light beam emitted by the first light motor 6. The projection lens 14 has an imaginary focal curve or imaginary focal line which is imaged by the plane mirror 12. The imaginary focal curve or imaginary focal line passes through the reflecting surfaces 10.1, 10.2 and 10.3 so as to image the corresponding reflecting surfaces illuminated by the light sources 8.1, 8.2 and 8.3. The imaginary focal curves or lines are preferably located behind the reflecting surfaces 10.1, 10.2, and 10.3 (with respect to the main direction of propagation of the light beam reflected towards the plane mirror 12), and even more preferably between the light sources 8.1, 8.2, and 8.3 and the rear edges of the reflecting surfaces 10.1, 10.2, and 10.3. This type of arrangement makes it possible to create a projected light beam with a sharp horizontal cutoff by imaging the rear edges.

[0034] The illumination module 2 also comprises a second illumination sub-module 16, which essentially consists of a second light motor 18 and second optical devices 24 and 26. In a similar manner to the first illumination sub-module 4 described above, the second light motor 18 is configured to generate a second reflected light beam, and the second optical devices 24 and 26 are configured to project the second reflected light beam as a second projected light beam. A second light collector 22 comprises reflective surfaces 22.1, 22.2, and 22.3 in the form of open cavities facing the corresponding light sources 20.1, 20.2, and 20.3. Reference is made to the description of the first illumination sub-module 4.

[0035] It can be seen that the first and second lighting sub-modules 6 and 18 are mounted on a plate 11 inclined by an angle α about an axis of inclination 13. This plate is horizontal and transverse to the motor vehicle when the lighting module is mounted and operational on the motor vehicle. The axis of inclination 13 corresponds to the axis y of the Cartesian coordinate system xyz. The axis x is parallel to the optical axis 28 of the lighting module 2 and to the longitudinal axis of the motor vehicle (when the lighting module is mounted and operational on the motor vehicle). Under these conditions, the axis y is horizontal and the axis z is vertical. The angle of inclination α of the plate 11 is greater than 0° and less than 90°. In this first embodiment, the angle α is 60°, with the proviso that this inclination could be smaller or even larger, depending in particular on the space available on the motor vehicle to accommodate the lighting modules.

[0036] It can also be seen that the first and second sub-modules 6 and 18 are positioned on the plate 11 in a vertical arrangement relative to the projection of their optical axis 28 onto the plate 11 (i.e. relative to the intersection of a vertical longitudinal plane with the plate 11). This arrangement on the plate 11, combined with its tilt α and the presence of the plane mirrors 12 and 24 on the plate 11, makes it possible to create first and second projected light beams that overlap vertically and combine to form the overall projected light beam of the lighting module 2.

[0037] It can also be seen that the projection lenses 14 and 26 of the first and second optical devices of the first and second lighting sub-modules 4 and 16 are aligned to extend along a common extension parallel to the plate 11 or are inclined at a slight angle (less than 20°) relative to the plate 11. Referring to the front view (right-hand view) of FIG. 1 , the projection lenses 14 and 26 extend in a main direction indicated by an axis. This main direction is inclined at an angle γ to the longitudinal vertical plane in a horizontal projection of this main direction and to the optical axis 28 ( FIG. 2 ) in a vertical projection of this main direction. In this first embodiment, the angle γ is 20°. Advantageously, this angle is greater than 0° and less than 45°. This inclination is advantageous in that it facilitates the integration of the lighting module 2 into the motor vehicle, at least in cases where the space reserved for the lighting module on the outer surface of the motor vehicle (especially for reasons of the style of the motor vehicle) can have this type of inclination. The tilting of the main directions of the projection lenses 14 and 26 is made possible by the corresponding oblique arrangement of the illumination submodules 4 and 16, in particular the first and second light motors 6 and 18 and the plane mirrors 12 and 24, relative to the tilt axis 13 or axis y.

[0038] The plane mirrors 12 and 24 are parallel to the tilt axis 13 (and therefore to the direction y). They are each tilted at an angle β with respect to the normal to the plate 11. In this first embodiment, the angle β is approximately 30°. Advantageously, the angle is greater than 0° and less than 60°. The angle β becomes larger as the angle α becomes larger, and vice versa.

[0039] 3 shows the overall projected light beam of the lighting module 2, formed by the overlap of the first and second projected light beams of the first and second lighting sub-modules 4 and 16 (FIGS. 1 and 2). Each curve is a curve of the same illuminance (isophote) based on the Cartesian coordinate system HV (H is the horizontal axis, V is the vertical axis, and the intersection of the axes H and V is the optical axis 28 of the lighting module). It can be seen that the overall light beam has a horizontal upper cutoff a little below the axis H. It can thus be related to the lighting function of motor vehicles with cutoff, commonly called "low beam".

[0040] FIG. 4 shows the working principle of the two lighting sub-modules 4 and 16, respectively, of the lighting module 2 of FIGS.

[0041] For purposes of clarity of illustration, a single reflective surface 10.1, 10.2, 10.3, 22.1, 22.2, or 22.3 in the form of an open cavity is representatively depicted, and thus a single light source 8.1, 8.2, 8.3, 20.1, 20.2, or 20.3 is shown associated with the representatively depicted reflective surface.

[0042] The projection lens 14 or 26 has a focal point 14.1 or 26.1 located behind the plane mirror 12 or 24. As a result of the influence of the plane mirror 12 or 24, the projection lens 14 or 26 has a virtual focal point 14.2 or 26.2 located on the reflective surface 10.1, 10.2, 10.3, 22.1, 22.2 or 22.3, advantageously at the rear edge of the reflective surface. The projection lens 14 or 26 is therefore configured to image the reflective surface illuminated by the associated light source (in particular the part of the reflective surface where the virtual focal point 14.2 or 26.2 is located).

[0043] The reflecting surface 10.1, 10.2, 10.3, 22.1, 22.2, or 22.3 advantageously has an elliptical or parabolic profile. The surface is advantageously a surface of revolution about an axis parallel to the optical axis of the light motor 6 or 18. Alternatively, it can be a free-form, swept, or asymmetric surface. The surface can also be composite, including multiple sections. The concentrator 10 or 22 in the form of a shell or enclosure is advantageously made of a material exhibiting good heat resistance, such as glass or a synthetic polymer such as polycarbonate (PC) or polyetherimide (PEI). The term "parabolic" generally applies to reflectors whose surface has a single focal point, i.e., a focal zone where light rays emitted by a light source located in this focal zone are projected over a long distance after reflection on the surface. By "projected over a long distance," we mean that the light rays do not converge toward an area located at a distance at least 10 times the dimension of the reflector. In other words, the reflected light rays do not converge toward a focal area, or if they do, this focal area is located at a distance greater than 10 times the dimension of the reflector. A parabolic surface may, but need not, have a parabolic portion. Reflectors having this type of surface are typically used alone to create a light beam. Alternatively, the reflector can be used as a projection surface in conjunction with an elliptical reflector. In this case, the light source of the parabolic reflector is the focal area for the light rays reflected by the elliptical reflector.

[0044] The light sources 8.1, 8.2, 8.3, 20.1, 20.2, or 20.3 are positioned at the focal point of the reflecting surface so that their light rays are collected and reflected along the optical axis of the light motor 6 or 18. At least some of these reflected light rays have an inclination angle of less than 25°, preferably less than 10°, relative to the axis in a vertical plane, so as to fall within the so-called Gaussian condition, thereby making it possible to obtain astigmatism (i.e., clarity of the projected image). Advantageously, these light rays are reflected by the rear part of the reflecting surface.

[0045] 5 and 6 show a lighting module according to a second embodiment of the present invention. The reference numerals of the first embodiment are used to designate identical or similar elements, but these numerals have been increased by 100. The descriptions of these elements in the first embodiment are also incorporated by reference. Specific numerals between 100 and 200 are used to designate elements specific to this embodiment.

[0046] The second embodiment of the illumination module 102 differs substantially from the first embodiment in that it includes a third illumination sub-module 130, which includes a third light motor 132 and third optical devices 138 and 140. The third light motor 132 in this case includes a single light source 134 and a single reflective surface 136 in the form of an open cavity facing the light source 134. The third optical device is similar to the first and second optical devices 112, 114, and 124, 126. The optical device is configured to image the reflective surface 136 illuminated by the light source 134 and to form a third projected light beam. This beam differs from the first and second projected light beams in that it has a narrower horizontal and vertical extent than the first and second projected light beams. This narrower horizontal extent is achieved by using only a single reflective surface, as opposed to three side-by-side reflective surfaces for the first and second projected light beams, respectively. The reduced vertical extent is achieved by providing a notch at the leading edge of the reflecting surface 136 of the light collector of the third light motor 132, and the trailing edge has a protrusion (not shown) whose image projected by the projection lens 140 forms an upper horizontal cutoff with a corresponding protrusion.

[0047] 6 shows the overall projected light beam of the illumination module 102, formed by the overlap of the first, second, and third projected light beams of the first, second, and third illumination sub-modules 104, 116, and 130 (FIG. 5). Each curve is a curve of the same illuminance (isophote) based on a Cartesian coordinate system HV (H is the horizontal axis, V is the vertical axis, and the intersection of the axes H and V passes through the optical axis of the illumination module).

[0048] As mentioned above, one can clearly see the horizontal cutoff formed by the third illumination sub-module 130, with a protrusion at the intersection of the axes H and V. This protrusion is centered on the optical axis of the illumination module 102.

[0049] 7 to 9 show a lighting module according to a third embodiment of the present invention. The reference numerals of the second embodiment are used to designate identical or similar elements, but these numerals are increased by 100. The descriptions of these elements in the first and second embodiments are also incorporated by reference. Specific numerals between 200 and 300 are used to designate elements unique to this embodiment.

[0050] FIG. 7 includes a perspective view and a front view of a lighting module according to a first embodiment of the present invention.

[0051] FIG. 8 is a side view of the lighting module of FIG.

[0052] The following description will be given in combination with FIG. 7 and FIG.

[0053] The second embodiment of the illumination module 202 is substantially different from the first embodiment in that it includes a fourth illumination sub-module 242 including a fourth light motor 244 and fourth optical devices 250 and 252. Additionally, the light concentrators of the first, second, third, and fourth light motors 206, 218, 232, and 244 each include a single reflective surface 210, 222, 236, and 248. Similarly, the first, second, third, and fourth light motors 206, 218, 232, and 244 each include a single light source 208, 220, 234, and 246.

[0054] 9 shows the overall projected light beam of the illumination module 202, formed by the overlap of the first, second, third, and fourth projected light beams of the first, second, third, and fourth illumination sub-modules 204, 216, 230, and 242 (FIG. 7). Each curve is a curve of the same illuminance (isophote) based on the Cartesian coordinate system HV (H is the horizontal axis, V is the vertical axis, and the intersection of the axes H and V passes through the optical axis of the illumination module). A horizontal cutoff without protrusions can be clearly seen at the intersection of the axes H and V.

[0055] 8 and 9, it should be noted that generally vertical displacement of the plate 211 carrying the first, second, third, and fourth illumination sub-modules relative to their respective projection lenses allows the overall projected light beam of the illumination module 202 to be displaced vertically (i.e., along axis V in FIG. 9). Upward displacement of the plate 211 with each illumination sub-module relative to the projection lenses 214, 226, 240, and 252 also displaces the overall projected light beam upward, and vice versa.

[0056] These displacements are diagrammed by vertical double-headed arrows in each of Figures 8 and 9.

[0057] It should be noted that this distinction applies to other embodiments as well.
