DETAILED DESCRIPTION
[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all of them. Generally, the components of the embodiments of the present disclosure described and shown in the drawings herein can be arranged and designed in various different configurations.
[0046] Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the present disclosure as claimed, but merely represents selected embodiments of the present disclosure. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort shall fall within the scope of protection of the present disclosure.
[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0048] In the description of the present disclosure, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.
[0049] In addition, the terms "first", "second", "third", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.
[0050] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present disclosure may be combined with each other.
[0053] 1 to 3 , an embodiment of the present disclosure provides a vehicle lamp module applicable to vehicle lamps and automobiles. The vehicle lamp module includes a light source assembly 10, and a concentrator 11, a cutoff element 12, and a lens 15 sequentially arranged along a principal optical axis s. The concentrator 11 is configured to converge light emitted by the light source assembly 10 and simultaneously emit the converged light toward the cutoff element 12 and the lens 15. The light is emitted through the lens 15 and projected to form a predetermined light pattern.
[0054] The light source assembly 10 includes a low beam light source 101 and a high beam light source 102. The optical axis a of the low beam light source is parallel to the main optical axis s or forms an angle of 0° to 5°, and the optical axis b of the high beam light source is parallel to the main optical axis s or forms an angle of 0° to 5°. The low beam light source 101 and the high beam light source 102 are respectively located on both sides of the main optical axis s.
[0055] The light source assembly 10 further includes a low-beam circuit board 101 a and a high-beam circuit board 102 a . The low-beam circuit board 101 a is provided with a plurality of low-beam light sources 101 arranged side by side, and the high-beam circuit board 102 a is provided with a plurality of high-beam light sources 102 arranged side by side.
[0056] The arrangement direction of the multiple low-beam light sources 101 is parallel to the arrangement direction of the multiple high-beam light sources 102, and they are respectively located on both sides of the main optical axis s. For example, as shown in Figure 3, the low-beam circuit board 101a and the high-beam circuit board 102a can be integrated to form a circuit board 100, on which six low-beam light sources 101 and four high-beam light sources 102 are arranged side by side. The light sources can specifically be LEDs.
[0057] Correspondingly, the concentrator 11 includes a low beam concentrator 11a and a high beam concentrator 11b. The low beam concentrator 11a and the high beam concentrator 11b can be arranged in one piece, or the low beam concentrator 11a and the high beam concentrator 11b can be arranged separately, preferably in one piece. This arrangement allows the low beam concentrator 11a and the high beam concentrator 11b to be as close as possible, and the vertical distance H between the low beam light source 101 and the high beam light source 102 is small, so that the upper and lower structures of the headlight module are compact, as shown in Figure 7.
[0058] The low beam concentrator 11 a includes a plurality of low beam concentrator units corresponding to the low beam light sources 101 and arranged side by side; the high beam concentrator 11 b includes a plurality of high beam concentrator units corresponding to the high beam light sources 102 and arranged side by side.
[0059] The low-beam light source 101 corresponds to the low-beam focusing unit, and the high-beam light source 102 corresponds to the high-beam focusing unit. As shown in Figure 5, the light incident surfaces of the low-beam concentrator 11a and the high-beam concentrator 11b can both form a cup-shaped surface 11c. The light emitted by the light source assembly 10 is focused by the cup-shaped surface 11c. That is, the low-beam focusing unit and the high-beam focusing unit can both be concentrators in the shape of a focusing cup.
[0060] The cup-shaped surface 11 c has a light-collecting function. The light emitted from the light source assembly 10 is collected by the corresponding cup-shaped surface 11 c and then emitted from the light-emitting surface of the concentrator 11 and toward the lens 15 , and finally emitted from the lens 15 .
[0061] In order for the concentrator 11 to collect the light emitted from the light source assembly 10 to the greatest extent possible, the surface size of the light incident surface of the concentrator 11 must be larger than the surface size of the light emitting surface of the light source. Due to thermal constraints, the distance between the light incident surface of the concentrator 11 and the light source assembly 10 is greater than a first preset distance. In other words, while ensuring that as much light as possible is collected by the concentrator 11, the light incident surface of the concentrator 11 must be far enough away from the light source to meet thermal constraints to prevent damage to parts. The distance between the light emitting surface of the concentrator 11 and the cutoff element 12 is less than a second preset distance. In other words, the light emitting surface of the concentrator 11 must be close enough to the light incident surface of the cutoff element 12 so that the light emitted by the concentrator 11 can pass through the cutoff element 12 to form a light-dark cutoff line and reduce the front and rear dimensions of the headlight module.
[0062] In the vehicle light module provided by the disclosed embodiments, the light source assembly 10 emits light toward a concentrator 11. Concentrator 11 is configured to converge the light emitted by the light source assembly 10 and simultaneously emit the light converged by concentrator 11 along an optical path toward a cutoff element 12 and a lens 15. After passing through lens 15, the light is emitted and projected to form a predetermined light pattern. The light source assembly 10 and concentrator 11 can be arranged along a principal optical axis s, with the optical axis a of the low-beam light source 101 and the optical axis b of the high-beam light source 102 arranged parallel to or slightly tilted from the principal optical axis s, resulting in a compact top-to-bottom structure for the vehicle light module. Furthermore, by adjusting the distance between the light source assembly 10, concentrator 11, cutoff element 12, and lens 15, the front-to-back structure of the vehicle light module is compact, ultimately achieving a small module size and low cost.
[0063] For example, as shown in Figure 4, for the low beam concentrator 11a, the low beam concentrating units 111c and 111d mainly realize the light brightness of the low beam center light type; the low beam concentrating unit 111a and the low beam concentrating unit 111f mainly realize the illumination width of the low beam widened light type (the arrangement direction of multiple low beam concentrating units); the low beam concentrating unit 111b and the low beam concentrating unit 111e are mainly configured to connect the low beam center light type and the low beam widened light type.
[0064] For the high beam concentrator 11b, the high beam concentrator unit 112a and the high beam concentrator unit 112d are mainly configured to realize the illumination width of the high beam light type (the arrangement direction of multiple high beam concentrator units); the high beam concentrator unit 112b and the high beam concentrator unit 112c are mainly configured to realize the light brightness of the high beam center light type.
[0065] The cutoff element 12 is configured to form a bright and dark cutoff line, and the lens 15 is configured to emit the final preset light pattern; the focus F of the lens 15 is located on the cutoff line structure 121 of the cutoff element 12, so that the light passing through the lens 15 forms a preset light pattern with a bright and dark cutoff line.
[0066] On this basis, as shown in Figure 5, the headlight module also includes an anti-focusing component 13, and a number of hollow areas 13a are formed at the bottom of the anti-focusing component 13. The principle of hot air rising is used to realize air flow and enhance heat dissipation, and an upward extending baffle 13b is formed at the front end of each hollow area 13a to prevent the sunlight 300 from being focused by the lens 15 and passing through the hollow area 13a to directly hit the lens bracket 14 located at the bottom, causing the risk of focusing burns.
[0067] Specifically, external sunlight 300 will strike lens 15, which will focus the sunlight 300, with the focal point falling on the lens holder 14 below. However, baffles 13b formed at the front ends of each hollow area 13a extend upward, effectively blocking the focused sunlight 300, preventing it from passing through the hollow area 13a and striking the lens holder 14 below the anti-focusing element 13. Furthermore, the low-beam light source 101 and the high-beam light source 102 will emit some stray light 400. Baffles 13b also effectively block some of the stray light 400 directed toward the lower portion of the lens holder 14, preventing it from entering the edges of the lens 15 and affecting the shape of the light pattern.
[0068] The vehicle light module also includes a lens holder 14, to which a heat sink 16, light source assembly 10, concentrator 11, cutoff element 12, anti-focusing member 13, and lens 15 are mounted. In other words, all components of the vehicle light module are assembled and positioned on the lens holder 14, shortening the tolerance chain and making the vehicle light module compact, thereby facilitating the realization of a small size.
[0069] Optionally, in order to further improve the heat dissipation efficiency, a through hole 141 is formed on the side wall of the lens holder 14 corresponding to the hollow area 13a. The hollow area 13a and the through hole 141 together form an air flow channel. The through hole 141 can be set as a large through hole 141 so as to correspond to all the hollow areas 13a; the through hole 141 can also be set as a plurality of through holes, which are respectively set corresponding to the hollow areas 13a.
[0070] As shown in Figure 6, in order to further improve heat dissipation, a ventilation hole 142 is provided on the other side wall of the lens holder 14. The ventilation hole 142 is provided corresponding to the hollow area 13a, so that air can form convection through the through hole 141, the hollow area 13a and the ventilation hole 142, thereby improving the air flow rate and facilitating the overall heat dissipation of the space inside the lens holder 14.
[0071] Optionally, the vehicle lamp module further includes a heat sink 16 , which is connected to the light source assembly 10 and is located on a side of the light source assembly 10 away from the concentrator 11 , and is configured to dissipate heat for the light source assembly 10 .
[0072] Optionally, the heat sink 16 is formed by combining bent aluminum and fins to efficiently dissipate heat from the light source assembly 10 .

Optionally, as shown in FIG. 7 , the low-beam light source 101 and the high-beam light source 102 are coplanar, and the optical axis a of the low-beam light source and the optical axis b of the high-beam light source are parallel to the main optical axis s.

[0076] The low beam light source 101 and the high beam light source 102 are coplanar, and the optical axis a of the low beam light source and the optical axis b of the high beam light source form an angle with the main optical axis s, that is, the low beam light source 101 and the high beam light source 102 are arranged on a circuit board 100, and the circuit board 100 is inclined relative to the main optical axis s but not perpendicularly arranged. In Figure 8, the circuit board 100 is inclined to the left, that is, the circuit board 100 rotates counterclockwise. In the light emitting direction, the optical axis a of the low beam light source is inclined away from the main optical axis s, and the optical axis a of the high beam light source is inclined close to the main optical axis s, and the optical axis a and the optical axis b respectively form a first angle with the main optical axis s.
[0077] Alternatively, as shown in Figure 9, optionally, the low beam light source 101 and the high beam light source 102 are coplanar, and the optical axis a of the low beam light source and the optical axis b of the high beam light source form an angle with the main optical axis s, that is, the optical axis a of the low beam light source and the optical axis b of the high beam light source are parallel and form a first angle with the main optical axis s respectively, and 0° < the first angle < 5°. Furthermore, in the light emitting direction, the optical axis a of the low beam light source is inclined close to the main optical axis s, and the optical axis b of the high beam light source is inclined away from the main optical axis s.
[0078] That is to say, the circuit board 100 in Figure 9 is tilted to the right, that is, the circuit board 100 rotates clockwise. In the light emitting direction, the optical axis a of the low beam light source is tilted close to the main optical axis s, and the optical axis b of the high beam light source is tilted away from the main optical axis s. The optical axis a of the low beam light source and the optical axis b of the high beam light source respectively form a first angle with the main optical axis s.

Furthermore, in the light emitting direction, the optical axis a of the low beam light source and the optical axis b of the high beam light source are respectively inclined away from the main optical axis s.
[0080] The low beam light source 101 and the high beam light source 102 are not coplanar, the low beam circuit board 101a and the high beam circuit board 102a are separately arranged, and the optical axis a of the low beam light source and the optical axis b of the high beam light source form a second angle and a third angle with the main optical axis s respectively, and 0°<the second angle<5°, 0°<the third angle<5°, that is, relative to the main optical axis s, the low beam circuit board 101a rotates counterclockwise by 0°~5°, and the high beam circuit board 102a rotates clockwise by 0°~5°, that is, the optical axis a of the low beam light source and the optical axis b of the high beam light source are respectively tilted away from the main optical axis s.
[0081] Referring to FIG11 , optionally, the low-beam light source 101 and the high-beam light source 102 are not coplanar, wherein the optical axis a of the low-beam light source is parallel to the principal optical axis s. In the light-emitting direction, the optical axis b of the high-beam light source is tilted close to the principal optical axis s, forming a fourth angle between the optical axis b of the high-beam light source and the principal optical axis s, and 0°<the fourth angle<5°, i.e., the high-beam circuit board 102a is rotated 0° to 5° counterclockwise relative to the principal optical axis s.

Alternatively, as shown in FIG14 , in the light-emitting direction, the optical axis a of the low-beam light source is tilted close to the principal optical axis s, forming an angle of 0° to 5°, i.e., the low-beam circuit board 101a is deflected 0° to 5° counterclockwise relative to the principal optical axis s.
[0083] In summary, in the vehicle lamp module provided by the embodiment of the present disclosure, all parts are assembled in the light-emitting direction, thereby improving assembly efficiency; all parts are positioned on the lens bracket 14, thereby shortening the tolerance chain; the concentrator 11 is configured to converge the light emitted by the light source assembly 10, and at the same time emit the converged light along the optical path to the lens 15; the cutoff element 12 is located between the concentrator 11 and the lens 15 and is configured to form a bright and dark cutoff line, and the focus of the lens 15 is located on the cutoff line structure 121 of the cutoff element 12; the light source assembly 10 and the concentrator 11 are arranged along the main optical axis s and are directionally assembled with the cutoff element 12; the high-beam light source 102 and the low-beam light source 101 can be arranged in the same plane, and a low-cost heat sink 16 made of extruded aluminum, bent aluminum plate, etc. can be used to dissipate heat from the light source. The headlight module is compact along the principal optical axis s. The components of the disclosed headlight module are already spaced at minimum distance, minimizing their size. The light source assembly 10, concentrator 11, and cutoff element 12 are already spaced at minimum distance; if they were any closer, the concentrator 11 would interfere with the cutoff element 12. The module's top and bottom structure is compact, with the optical axes of the low-beam light source 101 and high-beam light source 102 parallel or slightly tilted to the principal optical axis s. This compact structure results in a small module size and low cost. The high-beam circuit board 102a and the low-beam circuit board 101a can be integrated to minimize light output errors. Directed assembly via the lens holder 14 improves production efficiency.

This vehicle lighting device includes the same structure and benefits as the vehicle lighting module in the aforementioned embodiments. The structure and benefits of the vehicle lighting module have been described in detail in the aforementioned embodiments and will not be repeated here.
[0085] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims. Industrial Applicability
[0086] In summary, the present disclosure provides a headlight module, in which the optical axes of the low beam light source and the high beam light source are arranged parallel to or slightly inclined with the main optical axis, so that the upper and lower structures of the headlight module are compact. In addition, by setting the distance between the light source assembly, the concentrator, the cut-off element, and the lens, the front and rear structures of the headlight module are made compact, ultimately achieving the effect of small module size and low cost.
