The first outer surface is located on the side of the reflecting surface away from the emitting surface. The reflecting surface and the first outer surface are connected through a first chamfer surface. In this way, the reflecting surface and the first outer surface are connected through the first chamfer surface, so that no sharp corner is formed between the reflecting surface and the first outer surface.

Description

Technical Field

[0001] This application relates to the field of lens manufacturing technology, and in particular to a lens module and a vehicle lamp. Background Technology

[0002] Currently, when meeting oncoming traffic at night, if the headlights are too bright or the angle of illumination is too high, the strong light can cause temporary blindness to the oncoming driver, making it difficult for them to accurately judge the road conditions and increasing the risk of rear-end collisions or collisions.

[0003] In related technologies, the headlights employ a design that forms a cutoff line between light and dark. Specifically, the reflector bowl inside the headlight reflects and focuses the light emitted by the light source, and the lens further shapes and collimates the light to form a beam with a clear boundary, which is the cutoff line between light and dark. The cutoff line between light and dark can concentrate the light on the road surface, reduce direct irradiation to people's eyes, and prevent people from being unable to observe the surrounding environment due to glare.

[0004] In lens manufacturing, a mold-forming process is typically used. This involves placing the lens material into a specific mold, allowing it to cool and solidify to form the desired lens shape. However, the edges and corners that form the cutoff line on the lens are quite sharp. This results in sharp, convex corners in the mold corresponding to these corners. After prolonged use, these sharp corners in the mold are prone to wear, causing the produced lens to lose its original cutoff line design and the cutoff line to shift. Utility Model Content

[0005] In view of this, embodiments of this application provide a lens module and a vehicle lamp to solve the technical problem that the cutoff line on the vehicle lamp will be offset.

[0006] In a first aspect, this application provides a lens module, which includes: The surface exposed to light; The reflective surfaces are arranged along the first direction with the incident light surface; The light-emitting surface and the reflective surface are arranged along the second direction, and the light-incident surface and the reflective surface are located on the same side of the light-emitting surface, and the second direction is perpendicular to the first direction; The first outer surface is located on the side of the reflective surface away from the light-emitting surface; The reflective surface is connected to the first outer surface via a first chamfered surface.

[0007] Thus, the edge of the reflective surface near the first outer surface determines the position of the cutoff line between light and dark in the light pattern. In this embodiment, the reflective surface and the first outer surface are connected by a first chamfered surface, so that no sharp angle is formed between the reflective surface and the first outer surface. Reflected on the mold for producing the lens module, a protrusion appears on the mold at the position corresponding to the edge of the reflective surface. The protrusion is more wear-resistant than a sharp convex corner structure. During the long-term production of the lens module, the reflective surface on the lens module can retain the original design, and the cutoff line between light and dark in the light pattern emitted from the light-emitting surface will not shift.

[0008] In addition, since the reflective surface and the first outer surface are connected by the first chamfered surface, there is a sufficiently large space between the reflective surface and the first outer surface, which makes it easy to clean the dust between the reflective surface and the first outer surface. That is, no dust will accumulate between the reflective surface and the first outer surface. When using a blue light scanning tool to measure the surface shape of the lens module, the edge line of the reflective surface can be measured very easily, thereby controlling the product quality of the lens module.

[0009] As an optional implementation, the first chamfered surface is a first arc surface, and the first arc surface is recessed in the direction close to the light-incident surface.

[0010] In this way, a transition groove can be formed between the reflective surface and the first outer surface. The first arc surface is the bottom surface of the transition groove. This is reflected on the mold for producing the lens module. The position on the mold corresponding to the edge of the reflective surface is a protrusion with an arc-shaped top surface. The protrusion with an arc-shaped top surface will be more wear-resistant and can further extend the service life of the mold.

[0011] As an optional implementation, the number of reflective surfaces is multiple, and the multiple reflective surfaces are arranged sequentially along a third direction, which is perpendicular to both the first direction and the second direction; A second chamfered surface is provided between two adjacent reflective surfaces.

[0012] In this embodiment, the lens module can be applied to the low beam headlight. The low beam headlight can include multiple independent light sources, each of which is matched with a reflective surface. Through electronic control, the brightness or on / off state of each independent light source can be adjusted individually, so that the low beam headlight can flexibly adjust the light pattern and illumination range according to different driving scenarios and needs.

[0013] Specifically, when an oncoming vehicle is detected, the electronic control system quickly adjusts the brightness of the individual light sources in the corresponding area or turns off some light sources to prevent glare for oncoming drivers, thereby reducing the potential risk of traffic accidents. When driving on curves, the electronic control system adjusts the angle and range of the low beam headlights according to the steering wheel angle and vehicle speed to ensure that the road surface on the inside of the curve is adequately illuminated, improving driving safety.

[0014] Two adjacent reflective surfaces are connected by a second chamfered surface, which allows them to be connected more smoothly without forming sharp corners. This is reflected in the mold used to produce the lens module, where protrusions appear at the corresponding positions between the two reflective surfaces, increasing the mold's lifespan. Furthermore, the reflective surfaces on the lens module can maintain their original design during long-term production.

[0015] As an optional implementation, the second chamfered surface is connected to the first chamfered surface.

[0016] In this way, the outer edges of the reflective surface are connected to the smooth arc surface. When this is reflected on the mold for producing the lens module, the position of the reflective surface on the mold is defined by a bump structure, which can further extend the service life of the mold. During the long-term production of lens modules, the reflective surface on the lens module can retain the original design.

[0017] As an optional implementation, the second chamfered surface is a second arc surface, which is recessed towards the light-incident surface, and two adjacent reflective surfaces are connected through the second arc surface.

[0018] In this way, two adjacent reflective surfaces are connected by a second arc surface, which allows a groove to be formed between the two adjacent reflective surfaces. The second arc surface is the bottom surface of the groove. This is reflected on the mold for producing the lens module. The corresponding position on the mold between the two adjacent reflective surfaces is a protrusion with an arc-shaped top surface. The protrusion with the arc-shaped top surface is more wear-resistant and can further extend the service life of the mold.

[0019] As an optional implementation, the plurality of reflective surfaces include a first reflective surface and a second reflective surface, wherein the first reflective surface is disposed adjacent to the second reflective surface, and the first reflective surface is disposed closer to the incident light surface than the second reflective surface.

[0020] Thus, the second reflective surface is further away from the incident light surface than the first reflective surface. The second reflective surface and the first reflective surface can form a stepped or layered structure. Light rays entering the lens module from the incident light surface need to travel a longer path to reach the second reflective surface. The layered reflection design makes the light more concentrated in the target area, reduces scattering and ineffective reflection, and improves light utilization efficiency.

[0021] As an optional implementation, there are multiple light-emitting surfaces, which are arranged sequentially along the third direction, and one light-emitting surface is correspondingly provided with one reflective surface. The light-emitting surface is a convex arc surface, and the light-emitting surface protrudes in a direction away from the reflecting surface.

[0022] In this embodiment, the lens module can be applied to the low beam headlight. When the low beam headlight is installed on the vehicle body, multiple light-emitting surfaces can be arranged sequentially along the width of the vehicle body, so that the low beam headlight can cover a wider road area. Compared with a low beam headlight with a single light-emitting surface, a low beam headlight with multiple light-emitting surfaces can provide a wider lateral field of vision, enabling the driver to detect obstacles, pedestrians or other vehicles on both sides of the road earlier when driving at night, thereby improving driving safety.

[0023] In addition, the light emitted from different light-emitting surfaces can complement and superimpose each other, forming a more uniform lighting effect on the road. This avoids the bright and dark areas caused by uneven illumination from a single light source, reduces driver visual fatigue, and improves driving comfort.

[0024] Secondly, under different road conditions, such as curves and slopes, the arrangement of multiple light-emitting surfaces can better adjust the direction and range of light illumination. For example, when driving on a curve, by controlling the brightness or opening status of different light-emitting surfaces, the light can be more concentrated on the inside of the curve, improving the driver's ability to observe the curve.

[0025] As an optional implementation, a third arc surface is provided between two adjacent light-emitting surfaces, the third arc surface being recessed towards the reflective surface, and the two adjacent light-emitting surfaces are connected through the third arc surface.

[0026] Thus, two adjacent light-emitting surfaces are connected by a third arc surface, forming a groove between them. The third arc surface is the bottom surface of this groove. Reflected on the mold used to produce the lens module, the corresponding position on the mold between the two adjacent light-emitting surfaces is a protrusion with an arc-shaped top surface. This protrusion is more wear-resistant, further extending the mold's lifespan. Additionally, it prevents dust accumulation between the two adjacent light-emitting surfaces.

[0027] As an optional implementation, the lens module further includes: A first side surface, the first side surface being connected to the light-emitting surface and the light-incident surface; The second side is arranged along the first direction with the first side, and the second side is connected to the light-emitting surface; The third side is connected to the side of the second side away from the light-emitting surface, and the third side is set at an angle to the second side. The third side is also connected to the reflective surface. There is a thick-walled light-emitting structure between the first side and the second side.

[0028] Thus, a thick-walled light-emitting structure is formed between the first and second sides. The thick-walled light-emitting structure can effectively improve the illumination uniformity of the light-emitting surface and prevent light from concentrating in one area on the light-emitting surface, thereby reducing the occurrence of bright spots and dark areas.

[0029] Secondly, this application also provides a vehicle light, which includes: Lamp housing; The lens module described above is disposed within the lamp housing; A light source is disposed inside the lamp housing, and the light source is positioned opposite to the light incident surface; The light emitted by the light source is transmitted from the incident surface to the reflecting surface, and after being reflected by the reflecting surface, it forms a central parallel beam. The central parallel beam is finally emitted from the emitting surface, forming a light shape with a light cutoff line.

[0030] The vehicle headlight provided in this application, by employing the aforementioned lens module, enables the light emitted from the light-emitting surface to have a clear cutoff line between light and dark. Attached Figure Description

[0033] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0035] Currently, headlights, as a lighting component of automobiles, play an indispensable role in ensuring driving safety. For example, when driving at night or in special conditions such as low visibility and severe weather, headlights can emit light to clearly illuminate the road ahead, allowing drivers to detect obstacles, pedestrians, and other vehicles in advance, thus enabling them to make timely and accurate driving operations and effectively avoid collisions.

[0036] Specifically, the light pattern of headlights needs to meet a series of strict requirements. For example, the light pattern emitted by low beams must have a clear cutoff line between light and dark. On the one hand, this can prevent light from scattering upwards and causing glare to oncoming drivers, clearly delineate the illuminated and unilluminated areas, and ensure driving safety. On the other hand, it can concentrate the light to improve the brightness of road lighting, enhance the contrast between light and dark to optimize the lighting effect, reduce driver visual fatigue, and adapt to different scenarios.

[0037] When the low beam headlights are activated, a portion of the light is directed towards the reflector. The reflector then reflects this light at a preset angle to the output surface, which further focuses the light, directing it downwards onto the road surface in a concentrated manner, providing ample illumination for the area in front of the vehicle. Simultaneously, another portion of the light emitted by the headlights does not reach the reflector. At this point, a light-blocking device within the light path effectively blocks this portion of the light, preventing it from scattering upwards or into oncoming lanes. In this way, the light is primarily concentrated within a certain area in front of the vehicle, naturally creating a clear boundary between dark and bright areas – the cutoff line. The formation of the cutoff line is related to the reflector, and the edge of the reflector determines its position.

[0038] When manufacturing optical components with reflective surfaces, a molding process is typically used. This involves placing the material in a specific mold and allowing it to cool and solidify to form the desired shape. However, the reflective surface is usually directly connected to the outer surface of the optical component, resulting in a sharp angle between the edge of the reflective surface and the outer surface of the optical component. This causes a sharp, convex angle structure in the mold corresponding to the edge of the reflective surface. After prolonged use, this sharp convex angle structure in the mold is prone to wear. Using a worn mold to produce optical components results in the optical component failing to retain its original reflective surface design, and the cutoff line of the low beam will shift.

[0039] Based on this, this application provides a lens module 10 and a vehicle lamp. The lens module 10 includes a light-incident surface 1, a reflective surface 2, a light-emitting surface 3, and a first outer surface 4. The first outer surface 4 is located on the side of the reflective surface 2 away from the light-emitting surface 3, and the reflective surface 2 and the first outer surface 4 are connected by a first chamfered surface 5. In this way, the reflective surface 2 and the first outer surface 4 are connected by a transitional connection through the first chamfered surface 5, so that no sharp angle is formed between the reflective surface 2 and the first outer surface 4. Reflected on the mold for producing the lens module 10, the position on the mold corresponding to the edge of the reflective surface 2 presents a smooth protrusion. The protrusion is more wear-resistant than a sharp protruding corner structure. During the long-term production of the lens module 10, the reflective surface 2 on the lens module 10 can retain its original design, and the cutoff line of the light pattern emitted from the light-emitting surface 3 will not shift.

[0040] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0041] Please see Figure 1 and Figure 3 , Figure 1 This is a three-dimensional structural diagram of the lens module provided in an embodiment of this application, representing a first perspective. Figure 2 for Figure 1 Enlarged structural diagram at point A in the middle. Figure 3 This is a three-dimensional structural diagram of the lens module provided in an embodiment of this application from a second perspective.

[0042] As shown in the figure, this embodiment provides a lens module 10, which includes an incident surface 1, a reflecting surface 2, an emitting surface 3, and a first outer surface 4. The reflecting surface 2 and the incident surface 1 are arranged along a first direction, and the emitting surface 3 and the reflecting surface 2 are arranged along a second direction. The incident surface 1 and the reflecting surface 2 are located on the same side of the emitting surface 3. The second direction is perpendicular to the first direction. The first outer surface 4 is located on the side of the reflecting surface 2 away from the emitting surface 3. The reflecting surface 2 and the first outer surface 4 are connected by a first chamfered surface 5.

[0043] It should be noted that, Figure 1 The Z-axis direction is the first direction. Figure 1The X-axis direction is the second direction. Figure 1 The Y-axis direction is the third direction.

[0044] Optionally, the reflective surface 2 is a total reflection surface 2. The lens module 10 can be applied to the low beam headlights on the vehicle. After the low beam headlight is turned on, the light emitted by the light source is transmitted from the light-incident surface 1 into the lens module 10. A portion of the light is directed toward the reflective surface 2. The reflective surface 2 reflects this portion of the light to the light-exiting surface 3. The light-exiting surface 3 further focuses the light, so that the light is directly illuminating the road surface in a more concentrated form, providing sufficient illumination for the near area in front of the vehicle. At the same time, another portion of the light entering the lens module 10 is not directed toward the reflective surface 2, but toward the first outer surface 4. The first outer surface 4 can block this portion of the light, preventing it from scattering upwards and to the opposite lane. The light is mainly concentrated within a certain range in front of the vehicle, forming a cutoff line between light and dark in the light pattern.

[0045] Thus, the edge of the reflective surface 2 near the first outer surface 4 determines the position of the cutoff line between light and dark in the light pattern. In this embodiment, the reflective surface 2 and the first outer surface 4 are connected by a first chamfered surface 5, so that no sharp angle is formed between the reflective surface 2 and the first outer surface 4. Reflected on the mold for producing the lens module 10, a protrusion appears on the mold at the position corresponding to the edge of the reflective surface 2. The protrusion is more wear-resistant than a sharp convex corner structure. During the long-term production of the lens module 10, the reflective surface 2 on the lens module 10 can retain the original design, and the cutoff line between light and dark in the light pattern emitted from the light-emitting surface 3 will not shift.

[0046] In addition, since the reflective surface 2 and the first outer surface 4 are connected by the first chamfered surface 5, there is a sufficiently large space between the reflective surface 2 and the first outer surface 4, which makes it easy to clean the dust between the reflective surface 2 and the first outer surface 4. That is, no dust will accumulate between the reflective surface 2 and the first outer surface 4. When using a blue light scanning tool to measure the surface shape of the lens module 10, the edge line of the reflective surface 2 can be measured very easily, thereby controlling the product quality of the lens module 10.

[0047] Please see Figure 1 and Figure 2 In some embodiments, the first chamfered surface 5 is a first arc surface, and the first arc surface is recessed in the direction close to the light-incident surface 1.

[0048] Optionally, the reflective surface 2 protrudes in a direction away from the light-incident surface 1. The reflective surface 2 is connected to the first outer surface 4 through a first arc surface, and the first arc surface is recessed in a direction closer to the light-incident surface 1, so that a transition groove can be formed between the reflective surface 2 and the first outer surface 4. The first arc surface is the bottom surface of the transition groove. Reflected on the mold for producing the lens module 10, the position on the mold corresponding to the edge of the reflective surface 2 is a protrusion with an arc-shaped top surface. The protrusion with an arc-shaped top surface will be more wear-resistant and can further extend the service life of the mold.

[0049] In some other embodiments, the first chamfered surface 5 can be a plane, which is reflected on the mold for producing the lens module 10. The position on the mold corresponding to the edge of the reflective surface 2 is a protrusion, which can further extend the service life of the mold.

[0050] Please see Figure 1 In some embodiments, there are multiple reflective surfaces 2, which are arranged sequentially along a third direction. The third direction is perpendicular to both the first and second directions. A second chamfered surface 6 is provided between two adjacent reflective surfaces 2.

[0051] In this embodiment, the lens module 10 can be applied to the low beam headlight. The low beam headlight can include multiple independent light sources, each of which is matched with a reflective surface 2. Through electronic control, the brightness or on / off state of each independent light source can be adjusted individually, so that the low beam headlight can flexibly adjust the light pattern and illumination range according to different driving scenarios and needs.

[0052] Specifically, when an oncoming vehicle is detected, the electronic control system quickly adjusts the brightness of the individual light sources in the corresponding area or turns off some light sources to prevent glare for oncoming drivers, thereby reducing the potential risk of traffic accidents. When driving on curves, the electronic control system adjusts the angle and range of the low beam headlights according to the steering wheel angle and vehicle speed to ensure that the road surface on the inside of the curve is adequately illuminated, improving driving safety.

[0053] Two adjacent reflective surfaces 2 are connected by a second chamfered surface 6, so that the two adjacent reflective surfaces 2 can be connected more smoothly and no sharp corners are formed between the two reflective surfaces 2. As reflected on the mold for producing the lens module 10, the mold has protrusions at the positions corresponding to the two reflective surfaces 2, which can increase the service life of the mold. In addition, during the long-term production of the lens module 10, the reflective surfaces 2 on the lens module 10 can maintain their original design.

[0054] Please see Figure 2 In some embodiments, the second chamfered surface 6 is connected to the first chamfered surface 5.

[0055] Thus, the outer edges of the reflective surface 2 are all connected to the smooth arc surface. This is reflected on the mold for producing the lens module 10. The position of the reflective surface 2 on the mold is defined by a bump structure, which can further extend the service life of the mold. During the long-term production of the lens module 10, the reflective surface 2 on the lens module 10 can retain the original design.

[0056] Please see Figure 1 and Figure 2 In some embodiments, the second chamfered surface 6 is a second arc surface, which is recessed towards the light-incident surface 1, and two adjacent reflective surfaces 2 are connected through the second arc surface.

[0057] Optionally, two adjacent reflective surfaces 2 are connected by a second arc surface, so that a groove can be formed between the two adjacent reflective surfaces 2, and the second arc surface is the bottom surface of the groove. This is reflected on the mold for producing the lens module 10. The position on the mold corresponding to the two adjacent reflective surfaces 2 is a protrusion with an arc-shaped top surface. The protrusion with an arc-shaped top surface will be more wear-resistant and can further extend the service life of the mold.

[0058] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the plurality of reflective surfaces 2 include a first reflective surface 21 and a second reflective surface 22, wherein the first reflective surface 21 and the second reflective surface 22 are disposed adjacent to each other, and the first reflective surface 21 is disposed closer to the incident light surface 1 than the second reflective surface 22.

[0059] Thus, the second reflective surface 22 is further away from the light-incident surface 1 than the first reflective surface 21. The second reflective surface 22 and the first reflective surface 21 can form a stepped or layered structure. Light rays entering the lens module 10 from the light-incident surface 1 need to travel a longer path to reach the second reflective surface 22. The layered reflection design makes the light more concentrated in the target area, reduces scattering and ineffective reflection, and improves light utilization efficiency.

[0060] In this embodiment, the first reflective surface 21 has a side near the second reflective surface 22 as a first side, and the second reflective surface 22 has a side near the first reflective surface 21 as a second side. The second side is further away from the light-incident surface 1 than the first side. The second side is connected to the transition arc surface, the transition arc surface is connected to the second arc surface, and the second arc surface is connected to the first side, so that the second reflective surface 22 can be smoothly connected to the first reflective surface 21, thereby preventing the formation of a sharp angle between the second reflective surface 22 and the first reflective surface 21.

[0061] Please see Figure 1 and Figure 4In some embodiments, there are multiple light-emitting surfaces 3, which are arranged sequentially along a third direction, and one light-emitting surface 3 is correspondingly provided with one reflective surface 2. The light-emitting surface 3 is a convex arc surface and protrudes in a direction away from the reflective surface 2.

[0062] In this embodiment, the lens module 10 can be applied to the low beam headlight. When the low beam headlight is installed on the vehicle body, multiple light-emitting surfaces 3 can be arranged sequentially along the width direction of the vehicle body, so that the low beam headlight can cover a wider road area. Compared with a low beam headlight with a single light-emitting surface 3, a low beam headlight with multiple light-emitting surfaces 3 can provide a wider lateral field of vision, enabling the driver to detect obstacles, pedestrians or other vehicles on both sides of the road earlier when driving at night, thereby improving driving safety.

[0063] In addition, the light emitted from different light-emitting surfaces 3 can complement and superimpose each other, forming a more uniform lighting effect on the road, avoiding bright and dark areas caused by uneven illumination from a single light source, reducing driver visual fatigue, and improving driving comfort.

[0064] Secondly, under different road conditions, such as curves and slopes, the arrangement of multiple light-emitting surfaces 3 can better adjust the direction and range of light illumination. For example, when driving on a curve, the brightness or opening status of different light-emitting surfaces 3 can be controlled to make the light shine more concentratedly on the inside of the curve, improving the driver's ability to observe the curve.

[0065] It should be noted that the light-emitting surface 3 of the convex arc surface will refract the light reflected from the reflective surface 2 a second time, thereby expanding the illumination range of the light in the horizontal direction, thus expanding the illumination area of ​​the low beam headlight in the width direction of the vehicle body and further improving driving safety.

[0066] Please see Figure 1 and Figure 4 In some embodiments, a third arc surface 7 is provided between two adjacent light-emitting surfaces 3. The third arc surface 7 is recessed towards the reflective surface 2, and the two adjacent light-emitting surfaces 3 are connected by the third arc surface 7.

[0067] Optionally, two adjacent light-emitting surfaces 3 are connected by a third arc surface 7, forming a groove between them. The third arc surface 7 is the bottom surface of this groove. Reflected on the mold used to produce the lens module 10, the corresponding position on the mold between the two adjacent light-emitting surfaces 3 is a protrusion with an arc-shaped top surface. This protrusion is more wear-resistant, further extending the mold's service life. Additionally, it prevents dust accumulation between the two adjacent light-emitting surfaces 3.

[0068] Please see Figure 1 and Figure 3In some embodiments, the lens module 10 further includes a first side surface 81, a second side surface 82, and a third side surface 83. The first side surface 81 connects the light-emitting surface 3 and the light-incident surface 1. The second side surface 82 is arranged along a first direction with the first side surface 81 and is connected to the light-emitting surface 3. The third side surface 83 is connected to the side of the second side surface 82 away from the light-emitting surface 3 and is set at an angle to the second side surface 82. The third side surface 83 is also connected to the reflective surface 2. A thick-walled light-emitting structure 9 is provided between the first side surface 81 and the second side surface 82.

[0069] Optionally, both the first side surface 81 and the second side surface 82 are planar, and the first side surface 81 is parallel to the second side surface 82. The first side surface 81 connects the light-emitting surface 3 and the light-incident surface 1 in the first direction, which is the up-down direction. The first side surface 81 is located below the second side surface 82. The second side surface 82 is connected to the light-emitting surface 3. The third side surface 83 is connected to the side of the second side surface 82 away from the light-emitting surface 3. The third side surface 83 extends towards the first side surface 81 and is connected to the reflective surface 2. The third side surface 83 is perpendicular to the second side surface 82. A thick-walled light-emitting structure 9 is formed between the first side surface 81 and the second side surface 82. The thick-walled light-emitting structure 9 can effectively improve the illumination uniformity of the light-emitting surface 3 and prevent light from concentrating in one area on the light-emitting surface 3, thereby reducing the occurrence of bright spots and dark areas.

[0070] This embodiment also provides a vehicle lamp, which includes a lamp housing, a light source, and the aforementioned lens module 10. The lens module 10 is disposed inside the lamp housing, and the light source is disposed inside the lamp housing. The light source and the light-incident surface 1 are arranged opposite to each other. The light emitted by the light source is transmitted from the light-incident surface 1 to the reflective surface 2, and after being reflected by the reflective surface 2, it forms a central parallel beam. The central parallel beam is finally emitted from the light-out surface 3, forming a light shape with a light cutoff line.

[0071] The headlights should also include lamp holders and / or lamp covers that connect to the vehicle body; however, no specific restrictions are placed on the headlight structure. Generally, to improve overall vehicle assembly efficiency and facilitate future headlight maintenance, the headlights are typically connected to the vehicle body using detachable methods, such as screws or other threaded fasteners, or clips. No specific restrictions are placed on the connection method between the headlights and the vehicle body.

[0072] It should be noted that the vehicle light provided in this embodiment should also include other components that enable the vehicle light to operate normally. These other components will not be described in detail here.
