[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] The following is for reference. Figures 1-5 The vehicle lighting module 10 according to an embodiment of this application is described. The vehicle lighting module 10 includes a circuit board 11, a light shield 12, and a rotating assembly 13.

[0035] The circuit board 11 is equipped with a light source 111. A light-shielding member 12 has a light-transmitting hole 121 corresponding to the light source 111. A rotating assembly 13 can selectively rotate relative to the light-shielding member 12. The rotating assembly 13 is equipped with a plurality of lenses 14 arranged circumferentially at intervals, each lens 14 having a different shape. During rotation of the rotating assembly 13, the plurality of lenses 14 are sequentially positioned to correspond with the light-transmitting hole 121.

[0036] Currently, automotive headlight ADB (Adaptive High Beam) modules commonly employ multiple light sources paired with silicone focusing heads to achieve multi-pixel light patterns. However, using multiple light sources not only increases the hardware cost of the module but also significantly increases the complexity and energy consumption of the entire system. Furthermore, the high power consumption of multi-light source modules leads to heat concentration, while the limited heat dissipation capacity of the silicone focusing head makes it difficult to effectively dissipate heat, thus affecting the module's lifespan and performance stability. Therefore, reducing module heat is a technical challenge.

[0037] In response, this application proposes a vehicle lighting module 10, which forms a multi-pixel light pattern through multiple lenses 14, thereby reducing the number of light sources 111 and lowering the heat of the vehicle lighting module 10.

[0038] like Figure 1 As shown, specifically, the vehicle headlight module 10 may include a circuit board 11 and a light shield 12. The circuit board 11 may be provided with a light source 111, which may be an LED light, laser, or other light-emitting device. The light shield 12 may have a light-transmitting hole 121, which may be correspondingly provided with the light source 111. The light shield 12 may control the illumination range and angle of the light emitted by the light source 111. The light emitted by the light source 111 may be emitted through the light-transmitting hole 121. It should be noted that the circuit board 11 and the light shield 12 may be fixedly connected or indirectly fixed through other components.

[0039] Further, the vehicle lamp module 10 can further include a rotating assembly 13, the rotating assembly 13 can be selectively rotated relative to the light shielding piece 12, and the rotating assembly 13 can be further provided with a plurality of lenses 14, the number of the lenses 14 can be set according to the number of the pixel light types, the plurality of lenses 14 can be arranged at intervals along the circumference of the rotating assembly 13, and the shape of each lens 14 is different, when the light emitted by the light source 111 passes through different lenses 14, it can be refracted to different positions, it should be noted that the shape of each lens 14 can affect the refractive index, light transmittance and other related parameters of each lens 14, when the same light source 111 irradiates different lenses 14, the light can change the position of the light irradiation according to the parameters of the lens 14.

[0040] In the rotating process of the rotating assembly 13, the plurality of lenses 14 can be sequentially arranged corresponding to the light transmission hole 121, it can be understood that the plurality of lenses 14 are arranged at the rotating assembly 13, when the rotating assembly 13 rotates, it can drive the plurality of lenses 14 to move, and in the moving process, the plurality of lenses 14 can be sequentially arranged corresponding to the light transmission hole 121, that is, only one lens 14 is arranged corresponding to the light transmission hole 121 at the same time, with the sequential arrangement of the plurality of lenses 14 corresponding to the light transmission hole 121, the irradiation angle of the light can be quickly changed, thereby forming pixel light types of different positions and different sizes, such as Figure 1 The light can be irradiated to A through the lens 14. Therefore, the vehicle lamp module 10 can form multiple pixel light types through the plurality of lenses 14, which reduces the number of light sources 111 and reduces the heat of the vehicle lamp module 10.

[0041] In short, the vehicle lamp module 10 of the embodiment of the present application is provided with a rotating assembly 13, the rotating assembly 13 can move relative to the light shielding piece 12, and the rotating assembly 13 is provided with a plurality of lenses 14 arranged at intervals along the circumference, the shape of each lens 14 is different, when the rotating assembly 13 rotates, it can drive the plurality of lenses 14 to be sequentially arranged corresponding to the light transmission hole 121, the light emitted by the light source 111 passes through the light transmission hole 121 and irradiates to each lens 14, thereby forming pixel light types of different positions and different sizes, therefore, the vehicle lamp module 10 is provided with a rotating assembly 13 to realize that one light source 111 irradiates multiple pixel light types, compared with the prior art, the number of light sources 111 is reduced, thereby reducing the cost of the vehicle lamp module 10, improving the heat dissipation effect and service life of the vehicle lamp module 10.

[0042] In some embodiments of the present application, when the first lens 14 on the rotating assembly 13 moves to the optical position corresponding to the light transmission hole 121, the light source 111 (LED lamp) can be lit, at which time the light spot of the first lens 14 can be formed in front. When the rotating assembly 13 continues to rotate, the second lens 14 on the rotating assembly 13 moves to the optical position corresponding to the light transmission hole 121, the light source 111 can be lit, at which time the light spot of the second lens 14 can be formed in front. In this way, when the rotating assembly 13 rotates at high speed, after all the lenses 14 rotate one circle, the first lens 14 light spot is lit again, due to the visual pause of the human eye, the entire ADB light pattern is seen, as shown in Figure 1 and Figure 2 as shown in Figure 1 The example in the above is 12 lenses 14, which are a1, a2, a3, … a11, a12 in order, and the ADB light pattern irradiated by each lens 14 is b1, b2, b3, … b11, b12 in Figure 2 It should be noted that the light pattern of b1 can be irradiated by the light passing through the a1 lens 14, the light pattern of b2 can be irradiated by the light passing through the b2 lens 14, and so on until the light pattern of b12 can be irradiated by the light passing through the b12 lens 14.

[0043] Further, when the ADB light pattern area in front of the vehicle comes, the ADB light spot corresponding to the area where the vehicle is located needs to be extinguished, for example, as shown in Figure 3 Another schematic diagram of the ADB light spot and the basic low beam part is shown, and the light pattern area (b2) of the a2 lens 14 on the ADB light pattern band needs to be extinguished. Only when the a2 lens 14 rotates to the optical matching position corresponding to the light transmission hole 121, the light source 111 is extinguished, then the dark area of the b2 lens 14 is naturally formed on the ADB light pattern band, so that the coming vehicle in this area does not cause glare.

[0044] As shown in Figure 1 In some embodiments of the present application, the rotating assembly 13 can include a rotating piece 131 and a driving piece 132, the rotating piece 131 can be selectively rotated relative to the light shielding piece 12, and a plurality of lenses 14 can be arranged along the circumferential direction on the outer periphery of the rotating piece 131. Optionally, the cross section of the rotating piece 131 perpendicular to the thickness direction can be a triangle, a rectangle, a polygon, a circle or other irregular shape. The shape of the rotating piece 131 can be set according to actual needs, which is not limited here. When the pixel number of the ADB is required to be large, the number of lenses 14 arranged can be increased by expanding the diameter of the rotating piece 131, thereby increasing the pixel number of the ADB.

[0045] The driving member 132 can be in power connection with the rotating member 131, and the driving member 132 can be used to drive the rotating member 131 to rotate. Optionally, the driving member 132 can be provided with a driving shaft, and the driving shaft can be in power connection with the rotating member 131 through spline, interference, worm gear, etc. In some embodiments, the driving member 132 can be configured as a motor. By driving the rotating member 131 to rotate through the driving member 132, the movement of the plurality of lenses 14 can be realized, thereby forming different positions and different sizes of pixel light types.

[0046] As shown in Figure 1 some embodiments of the present application, the rotating member 131 and the circuit board 11 can be located on both sides of the light shielding member 12 in the thickness direction. It can be understood that the rotating member 131 can be located on the side of the light shielding member 12 away from the circuit board 11 in the thickness direction, that is, the circuit board 11 can be arranged on the inner side of the light shielding member 12 in the thickness direction, and the light source 111 at the circuit board 11 can be arranged opposite to the light transmission hole 121. The rotating member 131 can be arranged on the outer side of the light shielding member 12 in the thickness direction, and each lens 14 on the rotating member 131 can be arranged opposite to the light transmission hole 121 when moving. The above arrangement can separate the driving member 132 and the circuit board 11, which is beneficial to heat dissipation of the vehicle lamp module 10.

[0047] As shown in Figure 1 some embodiments of the present application, the rotating member 131 can be arranged in a horizontal direction. This arrangement can ensure that the light emitted through the lens 14 is not blocked by other lenses 14, thereby ensuring the reliability of the vehicle lamp module 10.

[0048] As shown in Figure 4 some embodiments of the present application, the rotating member 131 can be arranged in a horizontal direction. This arrangement can ensure that the light emitted through the lens 14 is not blocked by other lenses 14, thereby ensuring the reliability of the vehicle lamp module 10.

[0049] As shown in Figure 1 and Figure 4As shown, in some embodiments of this application, the vehicle headlight module 10 may further include a focusing element 15. The focusing element 15 may be disposed between the circuit board 11 and the light shield 12, and the focusing element 15 may be connected to at least one of the circuit board 11 and the light shield 12. In a specific embodiment, the focusing element 15 may be connected to the circuit board 11, and the light shield 12 may be connected to the focusing element 15. The focusing element 15 may be provided with an inlet end and an outlet end. The inlet end may be directly opposite the light source 111, and the outlet end may be directly opposite the light-transmitting hole 121. The focusing element 15 can concentrate the light emitted by the light source 111 into a small area to form a high-brightness beam, thereby improving the utilization rate of light and the lighting effect.

[0050] like Figure 4 As shown in some embodiments of this application, the vehicle headlight module 10 may further include a heat dissipation assembly 16. The heat dissipation assembly 16 may include a heat sink 161 and heat sinks 162. The heat sink 161 may be attached to and connected to the circuit board 11. Optionally, the heat sink 161 and the circuit board 11 may be detachably connected by screws or bolts, or by snap-fit ​​or plug-in, or by direct welding to the contact surfaces. Multiple heat sinks 162 may be configured, and these multiple heat sinks 162 may be spaced apart on the side of the heat sink 161 away from the circuit board 11. The heat sinks 162 may increase the heat dissipation area of ​​the heat sink 161, thereby improving the heat dissipation effect of the heat dissipation assembly.

[0051] like Figure 4 As shown, in some embodiments of this application, the light shield 12 can be constructed as an arc-shaped plate. By constructing the light shield 12 as an arc-shaped plate, the light shield 12 can better match the curved surface of the vehicle lamp, reduce light loss, and the arc-shaped plate helps to achieve a more reasonable layout in the limited space inside the vehicle lamp module 10, so that the light shield 12 maintains an appropriate distance and angle from other parts and avoids mutual interference.

[0053] like Figure 5 As shown, the headlight assembly 20 according to the embodiment of this application may include the headlight module 10 of the above embodiment. The number of headlight modules 10 may be one or more. When the number of ADB pixels is large, the requirement can be met by setting multiple headlight modules 10. When the headlight assembly 20 includes multiple headlight modules 10, the multiple headlight modules 10 may be staggered to save space.
