[0044] The core of this application is to provide a lighting module that can improve heat dissipation performance and reduce the cost of vehicle lights while ensuring optical performance.
[0045] Another key aspect of this application is to provide a vehicle light with the aforementioned lighting module.
[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0047] As modern cars continue to improve the heat dissipation and optical performance of integrated high and low beam headlights, they usually add cooling fans to improve the heat dissipation performance of the headlights. However, adding cooling fans will greatly increase the cost of the headlights, and the internal space of the headlights is relatively limited, making the installation of cooling fans inconvenient and increasing the overall size of the headlights.
[0048] Therefore, such as Figure 1 As shown in the illustration, this application discloses a lighting module including a lens assembly, a low beam assembly 100, and a high beam assembly 200. By employing independent low beam and high beam panels 102 in conjunction with the lens assembly, low beam and high beam patterns are formed, ensuring optical performance. Simultaneously, a low beam heat sink 101 is provided on the low beam panel 102, and a high beam heat sink 201 is provided on the high beam panel 202, enabling independent heat dissipation for the low beam and high beam sources. This improves heat dissipation performance, eliminates the need for additional cooling fans, and makes the lighting module more compact and smaller, reducing vehicle lighting costs.
[0049] The following will combine Figures 1 to 10 The lighting module disclosed in the embodiments of this application will be explained and described in detail.
[0050] Among them, such as Figures 1 to 3 As shown, the low beam assembly 100 may include a low beam heat sink 101 and a low beam lamp plate 102 disposed on the low beam heat sink 101. The low beam lamp plate 102 can be fixed to the mounting surface of the low beam heat sink 101 by fasteners such as bolts, so that the low beam particles on the low beam lamp plate 102 can emit light that is passed through the lens assembly to form a low beam pattern. Similarly, the high beam assembly 200 may include a high beam heat sink 201 and a high beam lamp plate 202 disposed on the high beam heat sink 201. The high beam lamp plate 202 can be fixed to the mounting surface of the high beam heat sink 201 by fasteners such as bolts, so that the high beam particles on the high beam lamp plate 202 can emit light that is passed through the lens assembly to form a high beam pattern. Meanwhile, the high beam assembly 200 and the low beam assembly 100 can have an angle between them, which can be a non-zero angle such as 60°, 90°, or 120°. The high beam heat sink 201 can be connected and fixed to the low beam heat sink 101 by fasteners such as bolts. Thus, by using independent low beam lamp panels 102 and high beam lamp panels 202 in conjunction with lens assemblies, low beam and high beam beam patterns can be formed to ensure optical performance. At the same time, low beam heat sinks 101 are set on the low beam lamp panel 102 and high beam heat sinks 201 are set on the high beam lamp panel 202 to achieve independent heat dissipation of the low beam and high beam light sources, thereby improving heat dissipation performance. There is no need to add a cooling fan, making the structure of the lighting module more compact and smaller in size, thus reducing the cost of vehicle lights.
[0051] In some embodiments, such as Figure 3As shown, both the low beam radiator 101 and the high beam radiator 201 can be made of one of the following: cold-forged radiator, die-cast radiator, or cold-extruded radiator. Since the low beam assembly 100 has a relatively complex structure, preferably, the low beam radiator 101 can be made of a die-cast radiator. Meanwhile, to meet the requirements of the overall headlight weight and high heat dissipation performance, the high beam radiator 201 can be made of a cold-forged radiator or a cold-extruded radiator. In this embodiment, the high beam radiator 201 can be made of a cold-forged radiator to meet the high heat dissipation performance requirements of the headlight.
[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the lens assembly may include an outer lens assembly 300, an inner lens 400, and a beam pattern baffle 500. The outer lens assembly 300 may include an outer lens 301 and a lens holder 302. The outer lens 301 is snapped onto the first end of the lens holder 302, and the low beam heat sink 101 is connected to the second end of the lens holder 302 via bolts or other fasteners to press the inner lens 400 between the lens holder 302 and the low beam assembly 100. Simultaneously, the beam pattern baffle 500 is located between the inner lens 400 and the outer lens 301, and is snapped onto the lens holder 302.
[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the lens holder 302 has a large-diameter end and a small-diameter end. The small-diameter end of the lens holder 302 is located at the first end of the lens holder 302, and the large-diameter end is located at the second end of the lens holder 302. The aperture of the small-diameter end of the lens holder 302 is not larger than the outer diameter of the outer lens 301, while the aperture of the large-diameter end of the lens holder 302 is larger than the outer diameter of the outer lens 301. A hook is provided at the first end of the lens holder 302, and a groove is provided on the outer lens 301 to engage with the hook. When installing the outer lens 301, the outer lens 301 can be inserted from the second end of the lens holder 302 into the mounting cavity of the lens holder 302 until it reaches the first end of the lens holder 302, causing the hook at the first end of the lens holder 302 to engage with the groove of the outer lens 301, thereby achieving a snap-fit fixation between the outer lens 301 and the lens holder 302. Furthermore, a slot for fixing the beam pattern baffle 500 is provided on the side wall of the mounting cavity of the lens holder 302, and a protrusion that mates with the slot is provided on the beam pattern baffle 500. When installing the beam pattern baffle 500, the protrusion of the beam pattern baffle 500 can be inserted into the slot to achieve a snap-fit fixation between the beam pattern baffle 500 and the lens holder 302.
[0054] Since the lens holder 302 is typically made of plastic, light from the outside of the illumination module, after being refracted by the outer lens 301, tends to focus onto the lens holder 302, causing ablation of the lens holder 302. Therefore, in some embodiments, such as... Figure 1and Figure 2 As shown, the lighting module may further include an anti-ablation sheet 600, which can be snapped onto the lens holder 302. The anti-ablation sheet 600 may be made of metal and is positioned within the focusing area of the lens holder 302 to prevent light from the outside of the lighting module from focusing onto the lens holder 302, thereby reducing the risk of ablation of the lens holder 302. Specifically, the end of the anti-ablation sheet 600 may have a retaining ring, and the first end of the lens holder 302 may have a protrusion that engages with the retaining ring. When installing the anti-ablation sheet 600, the protrusion at the first end of the lens holder 302 can be inserted into the retaining ring of the anti-ablation sheet 600 to achieve a snap-fit fixation between the anti-ablation sheet 600 and the lens holder 302.
[0055] To maximize luminous efficacy and, while improving luminous efficacy, also increase illumination distance and illumination width, in some embodiments, such as Figure 2 and Figure 3 As shown, the high beam assembly 200 can be located below the inner lens 400, and the low beam assembly 100 can be set perpendicular to the high beam assembly 200, with the low beam optical axis set parallel to the beam pattern baffle 500, as shown. Figure 4 As shown. When the light emitted from the low beam headlight panel 102 passes through the inner lens 400, it can be emitted from the low beam exiting surface 401 of the inner lens 400 and converged at the position of the beam pattern baffle 500, so that the parallel light passes through the outer lens 301 and is emitted to form a low beam pattern, such as... Figure 5 As shown. The inner lens 400 may have at least one total reflection surface 403. The high beam emitting surface 402 of the inner lens 400 may be located below the low beam emitting surface 401, and the total reflection surface 403 and the high beam emitting surface 402 of the inner lens 400 are inclined relative to each other. Simultaneously, the high beam optical axis may be perpendicular to the beam pattern baffle 500. Figure 6 As shown. When the light emitted from the high beam panel 202 enters the inner lens 400, it is reflected by the total internal reflection surface 403 and then emitted from the high beam exiting surface 402 of the inner lens 400. The light converges at the position of the beam pattern baffle 500 and is emitted as parallel light through the outer lens 301, forming the high beam pattern, as shown. Figure 7 As shown. It should be noted that the total reflection surface 403 can also be set to two or more, so that the light emitted by the high beam panel 202 can be reflected by multiple total reflection surfaces 403, and then emitted by the high beam output surface 402 of the inner lens 400 and converged at the position of the light pattern baffle 500, so that the parallel light is emitted through the outer lens 301 to form the high beam pattern.
[0056] In some embodiments, the light pattern baffle 500 may be made of two stacked metal plates of different thicknesses, joined together by riveting or laser welding. For ease of understanding, the two metal plates of different thicknesses are defined as the first metal plate and the second metal plate, respectively. The thickness of the first metal plate is less than that of the second metal plate, which allows the second metal plate to increase the strength of the light pattern baffle 500. The reflectivity of the thinner first metal plate is greater than that of the second metal plate. At the same time, an aluminum plating layer can be coated on the first metal plate to further improve its reflectivity, so that light can be reflected from the first metal plate to the outer lens 301 for emission. In addition, the aluminum plating layer can protect the first metal plate and extend the service life of the light pattern baffle 500. Of course, an aluminum plating layer can also be coated on the second metal plate to protect it.
[0057] In some embodiments, such as Figure 9 As shown, the beam pattern baffle 500 has two opposing sides, and a regulatory section 501 and a mounting section 502 are provided on both sides of the beam pattern baffle 500. The protrusion of the beam pattern baffle 500 can be disposed on the mounting section 502 and engage with the snap-fit of the lens bracket 302, so that the mounting section 502 of the beam pattern baffle 500 is snapped and fixed to the lens bracket 302. Simultaneously, the light emitted from the low beam lamp plate 102 can pass through the regulatory section 501 of the beam pattern baffle 500 and be emitted by the outer lens 301 to form the low beam III zone 700, thereby meeting the low beam regulatory requirements.
[0058] In some embodiments, such as Figure 9 As shown, to increase the visible area of the low beam and satisfy subjective perception, an inclined section 503 can be provided on at least one side of the beam deflector 500, and the inclined section 503 can be located between the regulatory section 501 and the mounting section 502. Specifically, the mounting section 502 can be located below the regulatory section 501, and the mounting section 502 and the regulatory section 501 can be horizontal, so that the inclined section 503 can be inclined from the edge of the regulatory section 501 toward the mounting section 502. When the light from the low beam passes through the inclined section 503, it can be emitted from above the inclined section 503, thereby increasing the visible area 5031 of the low beam on one side of the low beam III zone 700, as shown. Figure 10 As shown. Of course, inclined sections 503 can also be provided on both sides of the beam baffle 500 to increase the visibility area 5031 of the low beam on both sides of the low beam III zone 700. The specific requirements can be determined according to actual needs.
[0059] In some embodiments, such as Figure 8 and Figure 9As shown, to prevent glare to drivers, raised dots 504 can be provided on the light-patterned baffle 500. These raised dots 504 cause diffuse reflection of incident light, effectively reducing the concentration of light on a specific area. Furthermore, the raised dots 504 alter the light propagation path, dispersing or deflecting light that might otherwise directly enter the observer's eyes, reducing the likelihood of direct glare and thus lowering the risk of glare. Alternatively, specific surface treatments, such as sandblasting and anodizing, can be applied to the raised dots 504 to reduce specular reflection and further reduce glare. It should be noted that the raised dots 504 on the light-patterned baffle 500 can be added according to regulatory requirements.
