[0031] Another core of the present application is to provide a vehicle lamp having the above-mentioned lighting module.

[0032] Another core of the present application is to provide a vehicle having the above-mentioned headlight.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] Silicone lenses are widely used in ADB (Adaptive Driving Beam) lighting. As lighting performance improves, heat dissipation in silicone lenses presents a significant challenge. Currently, silicone lenses typically utilize a light-guiding whisker structure, secured by fixed baffles. To meet heat dissipation requirements, higher-performance silicone materials are often required, even requiring compromised lighting performance to meet ADB requirements. This results in poor lighting performance and increased costs.

[0035] For this reason, Figure 1 As shown, the embodiment of the present application discloses a lighting module, including a lens holder 100, a silicone lens 200, and a heat dissipation assembly 300. By disposing a first heat sink 302 between two adjacent rows of light guide teeth 201, the main heat of the silicone lens 200 is conducted to the external environment. At the same time, the second heat sink 303 disposed on the end side of the light guide teeth 201 assists in heat dissipation, thereby improving the heat dissipation effect of the silicone lens 200 and ensuring lighting performance.

[0036] The following will be combined Figure 1 The lighting module disclosed in the embodiments of the present application is specifically explained and illustrated.

[0037] Among them, such as Figure 1 As shown, the silicone lens 200 is arranged on the lens holder 100, and the silicone lens 200 may include at least two rows of light-guiding teeth 201. The multiple rows of light-guiding teeth 201 can improve the light transmittance of the silicone lens 200, enhance light scattering, and improve lighting performance. Specifically, the silicone lens 200 can adopt two rows of light-guiding teeth 201, or three rows, four rows, or more rows of light-guiding teeth 201 to adapt to the lighting requirements of different application scenarios. At the same time, the silicone lens 200 can adopt an integrated structure with the lens holder 100, thereby reducing the material consumption of the silicone lens 200, simplifying the assembly process of the silicone lens 200 and the lens holder 100, improving structural stability, optimizing optical performance, and improving temperature resistance and sealing.

[0038] To improve the heat dissipation of the silicone lens 200, the heat dissipation assembly 300 may include a fixed baffle 301, a first heat sink 302, and a second heat sink 303. Both the first heat sink 302 and the second heat sink 303 are disposed on the fixed baffle 301. The first heat sink 302 is located between two adjacent rows of light guide teeth 201, while the second heat sink 303 is located at the end of the light guide teeth 201, that is, on one side of the light guide teeth 201 in the end row of the silicone lens 200. Specifically, the first heat sink 302 and the second heat sink 303 may be riveted to the fixed baffle 301, and the fixed baffle 301 and the lens holder 100 may be secured by heat riveting. Furthermore, by disposing the first heat sink 302 between two adjacent rows of light guide teeth 201, the primary heat from the silicone lens 200 is transferred to the external environment. The second heat sink 303, disposed at the end of the light guide teeth 201, provides additional heat dissipation, thereby improving the heat dissipation of the silicone lens 200 and ensuring lighting performance. It should be noted that the first heat sink 302 , the second heat sink 303 and the fixed baffle 301 can be made of high thermal conductivity metal materials such as copper and aluminum to improve the heat dissipation effect of the heat dissipation assembly 300 .

[0039] In some embodiments, as Figure 1 As shown, the light guide teeth 201 are arranged in two rows. For ease of understanding, the two rows of light guide teeth 201 are defined as an upper row of light guide teeth 2011 and a lower row of light guide teeth 2012. The first heat sink 302 includes a first heat sink 3021 and a second heat sink 3022, which are located on either side of the lower row of light guide teeth 2012, respectively, to improve the heat dissipation effect of the silicone lens 200. Specifically, the first heat sink 3021 is located between the upper row of light guide teeth 2011 and the lower row of light guide teeth 2012, and is spaced apart from the upper row of light guide teeth 2011 and the lower row of light guide teeth 2012 to transfer the main heat of the silicone lens 200 to the external environment. At the same time, the second heat sink 303 can adopt an L-shaped structure, and one end of the second heat sink 303 is riveted to the fixed baffle 301, and the other end of the second heat sink 303 is gap-matched with the side of the upper row of light guide teeth 2011 away from the lower row of light guide teeth 2012 to achieve an auxiliary heat dissipation effect on the silicone lens 200.

[0040] In the above embodiment, the first heat dissipation plate 3021 and the second heat dissipation plate 3022 may be split structures and riveted to the fixed baffle 301 respectively. Of course, the first heat dissipation plate 3021 and the second heat dissipation plate 3022 may also adopt an integrated structure.

[0041] In some embodiments, as Figure 1As shown, the first heat sink 3021 and the second heat sink 3022 utilize an integrated structure. A connecting plate 3023 is disposed between the first heat sink 3021 and the second heat sink 3022. A first bend 3024 is formed by bending between the first heat sink 3021 and the connecting plate 3023, and a second bend 3025 is formed by bending between the second heat sink 3022 and the connecting plate 3023. The first bend 3024 and the second bend 3025 can utilize an arc-shaped structure to avoid stress concentration. The first heat sink 302 can be riveted to the fixed baffle 301 via the connecting plate 3023, simplifying the assembly process, reducing costs, and improving the stability of the heat sink assembly 300. At the same time, in order to avoid the influence of the first heat sink 302 on the installation of the silicone lens 200, a avoidance opening 3026 for avoiding the lower row of light guide teeth 2012 is opened on the connecting plate 3023, so that when the silicone lens 200 is installed, the tooth ends of the lower row of light guide teeth 2012 can be extended into the avoidance opening 3026, thereby avoiding the influence of the first heat sink 302 on the installation of the silicone lens 200.

[0042] The lighting module disclosed in the embodiment of the present application disposes a first heat sink 302 between two adjacent rows of light guide teeth 201, disposes a second heat sink 303 at the end of the light guide teeth 201, and simultaneously fixes the first heat sink 302 and the second heat sink 303 to a fixed baffle 301, thereby conducting heat from the silicone lens 200 to the external environment through the first heat sink 302, the second heat sink 303, and the fixed baffle 301. As can be seen from the above example, the lighting module provided by the present application disposes the first heat sink 302 between two adjacent rows of light guide teeth 201, thereby conducting the main heat of the silicone lens 200 to the external environment, while at the same time, the second heat sink 303 disposed at the end of the light guide teeth 201 provides auxiliary heat dissipation, thereby improving the heat dissipation effect of the silicone lens 200 and ensuring lighting performance.
