[0046] The present application provides a lighting module and a vehicle.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] like Figure 1-Figure 10 As shown, an embodiment of the present application provides a lighting module, which includes a light source, a reflector cup and a lens 1. The light emitted by the light source is reflected by the reflector cup and irradiates the light incident side of the lens 1, and then is emitted from the light emitting side of the lens 1 to form a target light shape. The light source is located at the near-field focus of the reflector cup; the optical center of the lens 1 is located at the far-field focus of the reflector cup.

[0049] It should be noted that the reflective cup is an ellipsoidal reflective cup, which has a near-field focus and a far-field focus. In practical applications, the number of lighting modules can be flexibly selected according to needs, that is, one or two or more lighting modules can be set to meet regulations and performance requirements. In practical applications, the number of light sources, reflective cups and lenses 1 set in the lighting module can be flexibly selected according to needs. The light source, reflective cup and lens 1 can be matched to form one group or two groups or more groups to meet regulations and performance requirements. The light source can be an LED light source. The lighting module can be used in various vehicle lighting systems such as headlights, fog lights, and taillights.

[0050] The present application creatively adjusts the position of lens 1. Instead of setting lens 1 at a position where the focus of lens 1 overlaps with the far-field focus of the reflector cup as in the prior art, lens 1 is set closer to the reflector cup, and the optical center of lens 1 is located at the far-field focus of the reflector cup. With this arrangement, lens 1 is placed at the narrowest position of the light, and can collect all the light, maximize the light output efficiency, increase the light intensity, and ensure the width of the target light shape. Moreover, under the premise of ensuring the light output efficiency, light intensity and the width of the target light shape, the length of the lighting module along the main optical axis direction of lens 1 is greatly shortened, so that the overall length of the lighting module is minimized. In addition, the light reflected by the reflector cup converges at the far-field focus of the reflector cup, and lens 1 is set exactly at the position where the light is most concentrated, so the size of lens 1 can be minimized, thereby further realizing the small size setting of the lighting module, which is beneficial to saving the space occupied by the installation of the lighting module and saving production costs. The main optical axis of lens 1 is located in the vicinity of Figure 1 The location of the middle dotted line.

[0051] Please refer to the attached Figure 1-9 In some embodiments of the present application, the lighting module is a low-beam lighting module capable of forming a low-beam light shape, in which case the light source is a low-beam light source 2, and the reflector is a low-beam reflector 3. The low-beam lighting module includes a low-beam light source 2, a low-beam reflector 3, and a light blocking member 4. The light reflected by the low-beam reflector 3 is partially blocked by the light blocking member 4 and then irradiated to the lens 1 to form a low-beam light shape with a light-dark cutoff line.

[0052] The light blocking member 4 is a light blocking plate structure. When the lighting module is a low-beam lighting module, the light blocking member 4 needs to be provided to block the low-beam light reflected by the low-beam reflector cup 3 and located at the bottom, so as to limit the maximum height of the light emitted by the lens 1, and form a low-beam light shape with distinct light and dark and a light and dark cut-off line to meet the regulations.

[0053] In some embodiments of the present application, the light blocking member 4 is located at the near-field focus of the low-beam reflector cup 3. “Near-field focus” refers to the position where the near-field focus is located, and a position close to the near-field focus or located near the near-field focus.

[0054] The present application creatively adjusts the position of the light blocking member 4. Unlike the prior art, the light blocking member 4 is no longer set at the far-field focus of the low-beam reflector cup 3, but is set at the near-field focus of the low-beam reflector cup 3. The light blocking member 4 is set at a close distance from the low-beam light source 2. In this way, a reliable shielding effect on the low-beam light can be exerted, and it becomes possible to shorten the length of the low-beam lighting module along the main optical axis direction of the lens 1.

[0055] Please refer to the attached Figure 7-9In some embodiments of the present application, the light blocking member 4 has an inclined surface 41 on one side close to the low beam reflector cup 3. The inclined surface 41 is inclined from bottom to top along the main optical axis of the lens 1 and in the direction from the low beam reflector cup 3 to the lens 1, and the left half 411 of the inclined surface 41 is higher than the right half 412; the low beam light source 2 is arranged on the left half 411 of the inclined surface 41.

[0056] It should be noted that the low beam light source 2 is arranged on the inclined surface 41 in a direction perpendicular to the inclined surface 41. The present application creatively arranges the low beam light source 2 on the light blocking member 4, thereby fixing the low beam light source and ensuring that the low beam light source 2 and the light blocking member 4 are both located at the near-field focus of the low beam reflector 3.

[0057] Please refer to the attached Figure 7-8 In some embodiments of the present application, the low beam light source 2 is adhered to the inclined surface 41 by means of a heat dissipation adhesive 5 .

[0058] It should be noted that the lighting module also includes a heat sink and a circuit board 6, the circuit board 6 is a PCB board, the circuit board 6 is fixedly arranged on the heat sink, and the low beam light source 2 is connected to the circuit board 6. The light blocking member 4 includes a first side surface close to the low beam reflector cup 3, and the upper half of the first side surface is an inclined surface 41.

[0059] As described above, the low-beam light source 2 is directly bonded and fixed to the inclined surface 41 by heat dissipation adhesive. The heat dissipation adhesive not only connects and fixes the low-beam light source 2, but also effectively diffuses the heat generated during the operation of the low-beam light source 2, thereby ensuring the heat dissipation and cooling effect of the low-beam light source 2, and further ensuring the reliability of the low-beam lighting module during use. Furthermore, by directly bonding and fixing the low-beam light source 2 to the inclined surface 41 by heat dissipation adhesive, the low-beam light source 2 can be closer to the upper edge of the light blocking member 4, so that the center point of the low-beam light shape is more concentrated to the edge of the light-dark cutoff line.

[0060] Please refer to the attached Fig. 9 In some embodiments of the present application, the low-beam light source 2 is connected to a circuit board 6 , and the circuit board 6 is disposed on the inclined surface 41 .

[0061] It should be noted that the light blocking member 4 includes a first side surface close to the low-beam reflector cup 3 , a middle portion of the first side surface is an inclined surface 41 , and an upper portion of the inclined surface 41 is a vertical plane.

[0062] As described above, the installation and setting structures of the low-beam light source 2 and the circuit board 6 are enriched, and a specific installation and setting structure can be selected according to actual needs, which has strong flexibility and applicability.

[0063] Please refer to the attached Fig.10In some embodiments of the present application, the lighting module is a high-beam lighting module capable of forming a high-beam light shape, in which case the light source is a high-beam light source 7, and the reflector is a high-beam reflector 8, that is, the high-beam lighting module includes the high-beam light source 7 and the high-beam reflector 8, and there is no need to set a light blocking member 4 in the high-beam lighting module. The high-beam light reflected by the high-beam reflector 8 directly irradiates the lens 1 and forms a high-beam light shape.

[0064] The high beam light reflected by the high beam reflector cup 8 converges to the far field focus of the high beam reflector cup 8, and the high beam light emitted through the light output side of the lens 1 has an upward inclination angle, so that a legal and compliant high beam light shape that does not irradiate downward to the ground can be directly obtained without the need to set up a light blocking member 4, which not only saves light blocking consumables, but also simplifies the structure, facilitates production and processing, and effectively saves costs.

[0065] Please refer to the attached Figure 1 , 10 In some embodiments of the present application, the focus of the lens 1 is located at the near-field focus of the reflective cup.

[0066] The light source emits light at the near-field focus of the reflector cup. After being reflected by the surface of the ellipsoidal reflector cup, all the light will converge at the far-field focus of the reflector cup. The focal length of lens 1 is equal to or approximately equal to the distance between the near-field focus and the far-field focus of the ellipsoidal reflector cup, so that the focus of lens 1 can coincide with the near-field focus of the reflector cup. This innovative setting can maximize the light output efficiency of lens 1 and avoid light overflow or blocking caused by focus misalignment. At the same time, please refer to the attached Figure 4 From the perspective of light distribution, a certain focal depth is provided. When the focal length of lens 1 is changed to change the target light shape, the light output efficiency of lens 1 remains almost unchanged, and the target light shape with sufficient clarity can still be obtained.

[0067] Please refer to the attached Figure 6 In some embodiments of the present application, the outer peripheral profile of the lens 1 is rectangular, the length of the lens is 3mm-6mm, and the width of the lens 1 is 3mm-6mm; for example, the length of the lens 1 is one of 3mm, 4mm, 5mm, 6mm, etc., and the width of the lens 1 is one of 3mm, 4mm, 5mm, 6mm, etc. Optionally, the length×width dimensions of the lens 1 are 3mm×3mm, 4mm×4mm, 6mm×6mm.

[0068] As described above, the size of the lens 1 is minimized, and the length and width of the lens 1 can be set to 6 mm or less, which is suitable for structures such as headlights with limited installation space. The specific size can be selected according to actual needs, and it is flexible and applicable.

[0069] In some parallel embodiments, the outer peripheral contour of lens 1 is a polygon, such as at least one of a pentagon and a hexagon, and the maximum outer diameter of lens 1 is 3mm-6mm; for example, the maximum outer diameter of lens 1 is one of 3mm, 4mm, 5mm, 6mm, etc.

[0070] As described above, the appearance of the lens 1 is enriched, and a specific shape can be selected according to needs, which is flexible and highly applicable.

[0071] In some parallel embodiments, the outer peripheral contour of the lens 1 is circular, and the diameter of the lens 1 is 3 mm-6 mm; for example, the diameter of the lens 1 is one of 3 mm, 4 mm, 5 mm, 6 mm, etc.

[0072] As described above, the appearance of the lens 1 is further enriched, and a specific shape can be selected according to needs, which has strong flexibility and applicability.
