[0031] The light source assembly 3 includes a light source component 31 and a light emitting portion 32 . DETAILED DESCRIPTION

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] Hereinafter, a low beam lamp module 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0034] like Figure 1-Figure 5 As shown, the low beam lamp module 100 according to the embodiment of the present invention includes: a micro-array lens 2 and a light source assembly 3, the micro-array lens 2 includes a plurality of lens units 21; the light source assembly 3 includes a plurality of light source components 31, each light source component 31 corresponds to a lens unit 21, and the light emitting portion 32 of each light source component 31 is located at the focal plane 23 of the corresponding lens unit 21, and the light source assembly 3 is constructed such that the light emitting portion 32 of a part of the light source components 31 is located above the optical axis 22 of the corresponding lens unit 21, and at least a part of a part of the light source components 31 is located below the optical axis 22 of the corresponding lens unit 21 to form a bright and dark cut-off line.

[0035] As a result, multiple light source elements 31 can jointly project a near-field light spot with a bright and dark cut-off line, simplifying the structure of the low beam module 100, reducing the overall size of the low beam module 100, facilitating layout, and improving the practicality of the low beam module 100.

[0036] For example, refer to Figure 1-Figure 2 As shown, the low beam lamp module 100 includes a micro-array lens 2 and a light source assembly 3. The micro-array lens 2 includes a plurality of lens units 21, and the plurality of lens units 21 are arranged in an array. The light source assembly 3 includes a plurality of light source components 31, and the plurality of light source components 31 are arranged at intervals, each light source component 31 corresponds to a lens unit 21, and the light emitting portion 32 of the light source component 31 is located at a position of the focal plane 23 of the lens unit 21 relative to the light source component 31, so that the light source component 31 can project light having a specific angle (which can be 0°) with the optical axis 22 through the lens unit 21 to form a light spot.

[0037] In which, the light source assembly 3 is constructed so that the light-emitting portion 32 of a part of the light source components 31 is located above the optical axis 22 of the corresponding lens unit 21, wherein at least a part of the part of the light source components 31 is located below the optical axis 22 of the corresponding lens unit 21, and the light source components 31 are constructed so that the projected light spot is located at a set position, such as the light spot projected by the light source component 31 located on the upper left side of the optical axis 22 of the corresponding lens unit 21 is located on the lower right side of the near-field light spot, so that multiple light source components 31 can jointly form a near-field light spot with a bright and dark cut-off line.

[0038] Specifically, Figure 3 As shown, the minimum vertical distance between the light source 31 located above the optical axis 22 of the corresponding lens unit 21 and the optical axis 22 is S1, at least part of the light emitting portion 32 of the light source 31 located in the lower left area is located below the optical axis 22 of the corresponding lens unit 21, and the vertical dimension of the light source 31 located at least partly below the optical axis 22 of the corresponding lens unit 21 is S2, and the minimum horizontal distance between the light emitting portion 32 of the light source 31 located below the optical axis 22 of the corresponding lens unit 21 and the optical axis 22 is S3, satisfying: S1 = f*tan0.57°, f*tan0.57°<S2≤f*tan1.14°, S3 = f*tan0.57°; wherein f is the focal length of the lens unit 21. The above is only an exemplary description, and other arrangements that can form a light-dark cutoff line that meets the requirements are within the protection scope of this application.

[0039] It should be noted that if Figure 3As shown, the plurality of light source elements 31 are distributed in a preset area of ​​the optical axis 22 of the corresponding lens unit 21, the length L of the preset area is 2*f*tan35°, and the height H is f*tan12°, so as to ensure that the light spot projected by the low beam lamp module 100 meets the standard. Figure 4 As shown, the light-emitting portion 32 of the light source 31 after being projected by the lens unit 21 has the following relationship with the light spot: W = f*tanα; wherein W is the distance that the light-emitting portion 32 of the light source 31 deviates vertically from the optical axis 22 of the corresponding lens unit 21, f is the focal length of the lens, and α is the deflection angle of the light spot projected by the light source 31. When the near-field light spot is projected at a specified distance (usually 25 meters), the position w' of the light spot offset from the optical axis 22 has the following relationship: w' = 25*tan(α) = 25*w / f.

[0040] According to the low beam lamp module 100 of the embodiment of the present invention, by arranging the light source 31 on the focal plane 23 of the lens unit 21, and allowing multiple light source components 31 to jointly project a near-field light spot with a bright and dark cut-off line, the structure of the low beam lamp module 100 can be simplified, the overall size of the low beam lamp module 100 can be reduced, the layout is facilitated, and the practicality of the low beam lamp module 100 is improved.

[0041] In some embodiments of the present invention, at least some of the light source components 31 are configured to be connected in parallel. In this way, when a single light source component 31 is damaged, the remaining light source components 31 can still work normally, reducing the probability of damage to the low beam module 100. This helps to improve the reliability of the low beam module 100.

[0042] In some embodiments of the present invention, at least some of the light source components 31 are connected in series. In this way, when a single light source component 31 fails, multiple light source components 31 connected in series all stop working to remind the user to repair in time. In this way, the visual blind spot caused by the failure of a single light source component 31 can be avoided, and the reliability of the low beam lamp module 100 is improved.

[0043] In some embodiments of the present invention, the low beam lamp module 100 includes multiple light source areas, each light source area is provided with multiple light source components 31, the positions of the multiple light source components 31 in each light source area and the optical axis 22 are the same, and the positions of the light source components 31 and the optical axis 22 in different light source areas are different.

[0044] For example, the low beam lamp module 100 may include multiple light source areas, each light source area is provided with multiple light source components 31, the relative positions between the multiple light source components 31 in each light source area and the optical axis 22 of the corresponding lens unit 21 are the same, and the positions of the light spots projected by the multiple light source components 31 in the same light source area are the same, and the illuminance E of the light spot corresponding to the light source area is the sum of the illuminances E1 of the multiple light source components 31. The relative positions between the light source components 31 in different light source areas and the optical axis 22 of the corresponding lens unit 21 are different, and the positions of the light spots projected by different light source areas are different, and the light spots projected by the multiple light source areas are used to jointly form a near-field light spot.

[0045] It can be understood that by arranging multiple light source elements 31 in the light source area to project onto the same light spot, the illumination requirement of a single light source element 31 can be reduced, which is convenient for design.

[0046] In the actual design process, the position of the light source 31 can be adjusted through a multi-dimensional processing platform so that multiple light sources 31 in the same light source area can be projected at the same position, and the light spots in different light source areas can form a near-field light spot.

[0047] Specifically, the light source component 31 can be installed on the fixture of the multi-dimensional adjustment platform, and then the lens unit 21 can be fixed on the fixture of the fixed base, and a corresponding partition pattern of the near-field light spot can be provided on the wall opposite to the multi-dimensional adjustment platform. At this time, the light source component 31 can be lit, and then the light source component 31 can be driven to move relative to the lens unit 21 along the Z axis, and the light spot projected by the lens unit 21 to the distant wall can be observed to determine the focal plane 122 of the lens unit 21 when the light source component 31 is brightest, and then the light source component 31 can be driven to move along the X-axis and Y-axis directions to move the light spot to the corresponding position on the wall to determine the installation position of the light source component 31. Among them, the Z axis is parallel to the optical axis 121 of the lens unit 21, and the X axis and the Y axis are perpendicular to the optical axis 121 of the lens unit 21.

[0048] In some embodiments of the present invention, the number of light source elements 31 in at least two light source regions is different, so that the light spots corresponding to the light source regions with different numbers of light source elements 31 have different illuminations, thereby facilitating meeting design requirements.

[0049] In some embodiments of the present invention, the number of light source elements 31 in the multiple light source areas is different, so that the illumination of the light spots corresponding to the multiple light source areas is different. For example, the illumination of the light spots corresponding to the multiple light source areas can be set to gradually decrease in the direction away from the HV point. In this way, the design rationality of the low beam lamp module 100 can be improved.

[0050] In some embodiments of the present invention, the light source elements 31 in each light source area are connected in parallel. In this way, when a single light source element 31 in a light source area fails, such as being damaged or flickering, the illumination of the light spot is reduced, but the light source area can still work normally. The above arrangement is conducive to improving the reliability of the low beam lamp module 100.

[0051] In some embodiments of the present invention, the light source components 31 of multiple light source areas are connected in series. In this way, when a single light source area fails, such as when all the light source components 31 in the light source area are damaged, the low beam lamp module 100 stops working to remind the user to repair it in time. In this way, the visual blind spot caused by the failure of a single light source area can be avoided, and the reliability of the low beam lamp module 100 is improved.

[0052] In some embodiments of the present invention, the low beam lamp module 100 of the embodiment of the present invention further includes: a shading member 1, the shading member 1 forms a plurality of shading cavities 11, light source members 31 are respectively installed in the plurality of shading cavities 11, the shading cavities 11 have light outlets 12, and a plurality of lens units 21 are respectively installed in the light outlets 12 of the plurality of shading cavities 11.

[0053] For example, refer to Figure 1-Figure 2 As shown, the low beam lamp module 100 further includes a shading member 1, which is formed with a plurality of shading cavities 11, which are arranged in an array, and a light outlet 12 is formed on the same side of the plurality of shading cavities 11. The micro-array lens 2 is mounted at the light outlet 12 of the shading cavity 11, and the plurality of lens units 21 of the micro-array lens 2 are arranged in an array and correspond one-to-one to the light outlets 12 of the plurality of shading cavities 11.

[0054] Multiple light source components 31 are respectively installed in multiple light shielding cavities 11. The light source components 31 are used to irradiate light toward the light outlet 12 so that the light can project a light spot through the corresponding lens unit 21. The light shielding component 1 is used to shield the lens unit 21 and the light source component 31 to prevent the remaining light sources from irradiating the lens unit 21, especially the adjacent light source components 31 from irradiating the lens unit 21. At the same time, a micro-matt structure, such as a matt coating, can be provided in the light shielding component 1. The micro-matt structure is used to eliminate the scattered light of the light source component 31 to prevent the scattered light from irradiating the corresponding lens unit 21. In this way, the projection quality of the near-field light spot can be improved.

[0055] It should be noted that the number of light source elements 31 and the number of light shielding cavities 11 are not absolutely the same, but may be different, and the present application does not impose any limitation on this.

[0056] During the specific installation process, the light source component 31 can be installed into the light shielding cavity 11 through the light outlet 12, and then the light source component 31 can be fixed on the side wall of the light shielding cavity 11 away from the light outlet 12 by gluing (or snapping, etc.), and then the microarray lens 2 can be installed on the side of the light shielding component 1 where the light outlet 12 is provided, and the lens unit 21 is opposite to the light source component 31, and the assembly of the low beam lamp module 100 can be completed.

[0057] In some embodiments of the present invention, a mounting port for mounting the light source component 31 is provided on a side of each light shielding cavity 11 away from the light outlet 12. For example, a mounting port (not shown in the figure) may be provided on a side of the light shielding cavity 11 away from the light outlet 12, and the light source component 31 may be installed in or removed from the light shielding cavity 11 through the mounting port. In other words, when a failure occurs in the light source component 31, the light source component 31 may be conveniently repaired through the mounting port without disassembling the microarray lens 2. Thus, the difficulty of repairing the low beam lamp module 100 may be reduced, and the practicality of the low beam lamp module 100 may be improved.

[0058] Furthermore, the installation opening can be provided to be blocked by a light shielding plugging piece. In a specific working process, when the light source component 31 is damaged, the light shielding plugging piece can be detached from the light shielding component 1, so that the installation opening is open, so that the user can replace the light source component 31 through the installation opening, and after the replacement is completed, the installation opening can be blocked by the light shielding plugging piece to seal the light source component 31 in the light shielding cavity 11. Through the above-mentioned setting, the interference to the light source component 31 can be reduced, the stability of the light source component 31 is improved, and the reliability of the low beam lamp module 100 is improved.

[0059] In some embodiments of the present invention, the thickness of the low beam module 100 can be set to be no greater than 10 mm; the thickness of the low beam module 100 can also be set to be no greater than 9 mm; the thickness of the low beam module 100 can also be set to be no greater than 8.5 mm, or no greater than 8 mm; the thickness of the low beam module 100 can also be set to be no greater than 7.5 mm, or no greater than 7 mm. Through the above settings, the low beam module 100 is easy to arrange, and the practicality of the low beam module 100 is improved.

[0060] In some embodiments of the present invention, the microarray lens 2 may be any one of a plastic lens, a glass lens, a gradient refractive index material lens, a Fresnel lens or a super lens, thereby being able to meet different working conditions.

[0061] In some embodiments of the present invention, the surface of the lens unit 21 close to the light source 31 can be any one of a plane, an aspherical surface, and a free-form surface, and the surface of the lens unit far from the light source 31 can be any one of a spherical surface, an aspherical surface, and a free-form surface. This helps to meet different working conditions.
