Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more particularly to a vehicle front combination lamp module and a vehicle. Background Technology

[0002] Vehicle front combination lights refer to the combination of lights installed at the front of a vehicle for illumination and signal transmission. They typically include high beams, low beams, turn signals, and position lights (indicating the vehicle's presence). Currently, the illumination and signal functions in vehicle front combination lights are basically separate visual surfaces. This not only fails to meet the trend of increasingly compact, novel, and diverse vehicle headlight designs, but also lacks the possibility of incorporating more intelligent, trendy, fun, and unique aesthetics into headlight designs. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a vehicle front combination lamp and a vehicle, such that the lighting light path and the signal light path in the vehicle front combination lamp share the same inner lamp cover, which does not affect the lighting performance and ensures the feasibility of the signal lights. This is conducive to the compact design of the vehicle front combination lamp, providing a new direction and new possibilities for the design of the vehicle front combination lamp, and making the style of the vehicle lights more novel and unique.

[0004] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0005] A vehicle front combination light, comprising:

[0006] The inner lamp cover includes a first surface and a second surface disposed opposite to each other along a first direction. The first surface is provided with a plurality of grooves, and the sidewalls of the grooves include a first optical surface. The first direction is the longitudinal direction of the vehicle. The inner lamp cover also includes a bottom end face and a top end face disposed opposite to each other along a second direction. The bottom end face is closer to the ground than the top end face. The second direction is the vertical direction of the vehicle.

[0007] A reflector and a first light source are located on the side of the first surface of the inner lampshade that faces away from the second surface. The light emitted by the first light source is reflected by the reflector, and at least part of the reflected light is incident on the first optical surface. After being refracted by the first optical surface, it is emitted from the second surface to form part of the illumination light pattern. The illumination light pattern includes at least one of a near beam light pattern and a far beam light pattern.

[0008] A second light source is located on the side of the bottom end face of the inner lamp cover away from the inner lamp cover. The light emitted by the second light source is arranged along a third direction, which is the left and right direction of the vehicle. The light emitted by the second light source is incident on the inner lamp cover from the bottom end face, and after total internal reflection by the first optical surface, it is emitted from the second surface to form the signal light emission light.

[0009] Optionally, the second light source includes an LED light source and a light guide structure. The light guide structure extends along the third direction, and the LED light source is located at one end of the light guide structure. The light emitted by the LED light source enters the light guide structure and, after passing through the light guide structure, forms light rays arranged along the third direction and pointing towards the bottom end face.

[0010] Optionally, the second light source is a line light source or a surface light source extending along the third direction.

[0011] Optionally, the second light source includes a plurality of point light sources arranged along the third direction.

[0012] Optionally, the bottom end face includes multiple patterned structures, which are used to diffuse the light emitted by the second light source, which is arranged along the third direction and points towards the bottom end face, along the third direction.

[0013] Optionally, on the first surface, the plurality of grooves are arranged in multiple rows along the third direction, and each row of grooves is arranged along the second direction;

[0014] Along the direction away from the bottom end face, the area of ​​the first optical surface of each row of grooves gradually increases.

[0015] Optionally, along the second direction, adjacent rows of grooves do not overlap at least partially.

[0016] Optionally, the first optical surface is a plane or a curved surface.

[0017] Optionally, the groove is prismatic, and the groove includes four sidewalls and a bottom surface, wherein the first optical surface is one of the sidewalls of the groove.

[0018] A vehicle comprising the vehicle front combination lamps described in any of the preceding claims.

[0019] Compared with existing technologies, the above technical solution has the following advantages:

[0020] In the vehicle front combination lamp provided in this application embodiment, a first light source, a reflector, and an inner lamp cover are combined to form a lighting lamp, and a second light source and an inner lamp cover are combined to form a signal lamp. That is, the lighting lamp path and the signal lamp path share the inner lamp cover. The inner lamp cover includes a first surface and a second surface arranged opposite each other in the vehicle's longitudinal direction, and a bottom end face and a top end face arranged opposite each other in the vehicle's vertical direction. The bottom end face is closer to the ground than the top end face. The first surface of the inner lamp cover is provided with multiple grooves, and the sidewalls of the grooves include a first optical surface. With this arrangement, for the lighting lamp, the light emitted by the first light source, after being reflected by the reflector, at least... Partially reflected light rays are incident on the first optical surface of the first surface of the inner lamp cover. After refraction by the first optical surface, they are emitted from the second surface of the inner lamp cover, forming part of the illumination light pattern. This, together with the light rays emitted by the first light source that are reflected by a mirror and then emitted through the non-recessed part of the inner lamp cover, forms the illumination light pattern. The illumination light pattern includes a low beam pattern and / or a high beam pattern. For the signal light, the light rays emitted by the second light source are arranged along the left-right direction of the vehicle and are incident on the inner lamp cover from the bottom end face. After total internal reflection by the first optical surface of the inner lamp cover, they are emitted from the second surface of the inner lamp cover, forming the signal light emission light. In this way, the vehicle's front combination lamp can ensure the feasibility of signal lights without affecting the lighting performance. Moreover, the lighting light path and the signal light path share the same inner lamp cover, which is conducive to the compact shape design of the vehicle's front combination lamp and provides new directions and possibilities for the shape design of the vehicle's front combination lamp, making the style of the lamp more novel and unique. In addition, the first optical surface of the inner lamp cover is designed to reflect the signal light light in a total reflection and then emit it in a directional manner, which can also improve the emission efficiency of the signal light.

Detailed Implementation

[0032] 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.

[0033] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0034] Secondly, this application provides a detailed description in conjunction with the schematic diagrams. When detailing the embodiments of this application, for ease of explanation, the accompanying drawings illustrating the structures may be partially enlarged, not to scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this application. In addition, actual manufacturing should include three-dimensional spatial dimensions of length, width, and depth.

[0035] As described in the background section, the lighting and signaling functions in existing vehicle headlights are basically separate visual surfaces. This not only fails to meet the trend of increasingly compact, novel, and diversified headlight designs, but also lacks the possibility of creating headlight designs that integrate intelligence, trendiness, fun, and unique aesthetics.

[0036] In view of this, embodiments of this application provide a vehicle front combination lamp. Figure 1 This application provides a schematic diagram of the structure of a vehicle front combination lamp according to an embodiment of the present application. Figure 1 As shown, the vehicle's front combination lamp includes an inner lamp cover 10, which includes a first surface 11 and a second surface 12 disposed opposite to each other along a first direction X. The first surface 11 is provided with a plurality of grooves T1, and the sidewalls of the grooves T1 include a first optical surface S1. The first direction X is the longitudinal direction of the vehicle. The inner lamp cover 10 also includes a bottom end face 13 and a top end face 14 disposed opposite to each other along a second direction Y. The bottom end face 13 is closer to the ground than the top end face 14. The second direction Y is the vertical direction of the vehicle.

[0037] like Figure 1 As shown, the vehicle's front combination lamp also includes a reflector 20 and a first light source 30 located on the side of the first surface 11 of the inner lamp cover 10 away from its second surface 12. The first light source 30, the reflector 20 and the inner lamp cover 10 together constitute a lighting lamp. The light emitted by the first light source 30 is reflected by the reflector 20, and at least part of the reflected light is incident on the first optical surface S1 of the first surface 11 of the inner lamp cover 10. After being refracted by the first optical surface S1, it is emitted from the second surface 12 of the inner lamp cover 10, forming part of the lighting pattern. Together with the light emitted by the first light source 30, which is reflected by the reflector 20 and then emitted through the non-recessed part of the inner lamp cover 10, the lighting pattern is formed. The lighting pattern includes at least one of the low beam pattern and the high beam pattern, that is, the lighting pattern includes the low beam pattern and / or the high beam pattern. In other words, the lighting pattern is the low beam pattern, or the lighting pattern is the high beam pattern, or the lighting pattern is both low and high beam patterns.

[0038] like Figure 1 As shown, the vehicle's front combination lamp also includes a second light source 40 located on the side of the bottom end face 13 of the inner lamp cover 10 facing away from the inner lamp cover 10. The second light source 40 and the inner lamp cover together constitute a signal light. For a better understanding of this application, Figure 2 and Figure 3They are shown respectively Figure 1 The diagram shows two viewing angles of the inner lampshade 10 and the second light source 40. Both viewing angles are from one side of the first surface 11 of the inner lampshade 10 towards the inner lampshade 10 and the second light source 40. Figures 1-3 It is understandable that the light emitted by the second light source 40 is arranged in the third direction Z, and the light emitted by the second light source 40 is directed towards the bottom end face 13 of the inner lamp cover 10. The light is incident on the inner lamp cover 10 from the bottom end face 13, and after total internal reflection by the first optical surface S1 of the inner lamp cover 10, it is emitted from the second surface 12 of the inner lamp cover 10 to form the signal light emitted from the signal lamp.

[0039] In this embodiment, the inner lampshade 10 is made of a colorless and transparent material so that lighting light and signal light can be emitted through the inner lampshade 10.

[0040] To better understand this application, Figure 4 It shows Figure 1 A partially enlarged schematic diagram of the groove T1 portion provided on the first surface 11 of the inner lampshade 10, combined with... Figures 1-4 As shown, optionally, the groove T1 can be prismatic, and the groove T1 can include four sidewalls A1 and a bottom surface A2. The first optical surface S1 is one of the sidewalls A1 of the groove T1. The four bottom corners of the groove T1 (i.e., the connecting corners between two adjacent sidewalls A1 and the bottom surface A2) can be rounded, so that it is easier to form multiple grooves T1 on the first surface 11 of the inner lampshade 10 in terms of manufacturing process.

[0041] It should be noted that the shape of the groove T1 is not limited in this application. Other options include that the groove T1 may not have a bottom surface A2, or the bottom surface A2 may be very small, although the manufacturing process is relatively more complicated. Alternatively, the groove T1 may include three side wall surfaces A1 or five or more side wall surfaces A1, but the first optical surface S1 is always one side wall surface A1 of the groove T1.

[0042] It should also be noted that the first optical surface S1 can be a plane or a curved surface. The design of the first optical surface S1 needs to meet two requirements: First, the first optical surface S1 is designed to perform total internal reflection on the light emitted from the second light source 40 that is incident on the inner lamp cover 10 from the bottom end face 13 of the inner lamp cover 10, so that the light after total internal reflection is emitted directionally from the second surface 12 of the inner lamp cover 10 to form the signal light emission light. In this way, not only can the regulatory requirements for the signal light emission light be met, so that more of the signal light emission light is emitted directly in front of the vehicle's front combination lamp, but the emission efficiency of the signal light can also be improved. Second, the first optical surface S1 is also designed to deflect the light emitted from the first light source 30 after being reflected by the reflector 20 towards the ground, so as not to affect the illumination light emitted from the first light source 30 after being reflected by the reflector 20 and then emitted through the inner lamp cover 10.

[0043] It is understandable that the illumination light emitted by the first light source 30, after being reflected by the reflector 20 and then emitted through the inner lampshade 10, includes not only the illumination light emitted by the first light source 30 after being reflected by the reflector 20 and then deflected towards the ground by the first optical surface S1, but also the illumination light emitted by the first light source 30 after being reflected by the reflector 20 and then emitted through the non-grooved portion of the inner lampshade 10. The illumination pattern emitted by the lamp is mainly formed by the reflector 20. If the first surface 11 of the inner lamp cover 10 does not have a groove, that is, if the first optical surface S1 is not provided on the first surface 11 of the inner lamp cover 10, the light emitted by the first light source 30 after being reflected by the reflector 20 and then transmitted through the inner lamp cover 10 forms the illumination pattern. However, if the first surface 11 of the inner lamp cover 10 has a groove, that is, if the first optical surface S1 is provided on the first surface 11 of the inner lamp cover 10, the light emitted by the first light source 30 after being reflected by the reflector 20 and then transmitted through the first optical surface S1 still constitutes part of the illumination pattern, thus having no or minimal impact on the illumination performance.

[0044] It is also understandable that both the lighting beams and the signal beams are emitted after being refracted by the second surface 12 of the inner lamp cover 10.

[0045] Figure 5 This illustration shows the lighting effect of a vehicle front combination lamp according to an embodiment of this application, combined with... Figure 2 , Figure 3 and Figure 5 As shown, it can be understood that the pattern of multiple grooves T1 distributed on the first surface 11 of the inner lamp cover 10 is the same pattern after the signal light is lit.

[0046] Optionally, the signal light formed by the combination of the second light source 40 and the inner lamp cover 10 can be a front position light or a turn signal, or it can have the functions of both. For example, the second light source 40 includes a first sub-light source and a second sub-light source. The first sub-light source and the inner lamp cover 10, or a part of the first sub-light source and the inner lamp cover 10, are combined to form a front position light. The second sub-light source and the inner lamp cover 10, or a part of the second sub-light source and the inner lamp cover 10, are combined to form a turn signal, depending on the specific situation.

[0047] In this embodiment, the second light source 40 is disposed on the side of the bottom end face 13 of the inner lamp cover 10 away from the inner lamp cover 10, rather than on the side of the top end face 14 of the inner lamp cover 10 away from the inner lamp cover 10. This is because, in fact, if the second light source 40 is disposed on the side of the top end face 14 of the inner lamp cover 10 away from the inner lamp cover 10, and the first optical surface S1 is adapted to be disposed, the light emitted by the second light source 40 that is incident on the inner lamp cover 10 from the top end face 14 of the inner lamp cover 10 can be totally internalized, so that the totally internalized light is directed out from the second surface 12 of the inner lamp cover 10 to form the signal light emitted by the signal light. However, if it is disposed in this way, the light emitted by the first light source 30 that is reflected by the reflector 20 and then incident on the first optical surface S1 will be deflected by the first optical surface S1 in the direction away from the ground, which will affect the lighting pattern.

[0048] In other words, in the vehicle front combination lamp provided in this application embodiment, the design of the first optical surface S1 of the first surface 11 of the inner lamp cover 10 and the placement of the second light source 40 on one side of the bottom end face 13 of the inner lamp cover 10 enable the lighting light path and the signal light path to share the inner lamp cover 10, ensuring the feasibility of the signal light without affecting the lighting performance. As can be seen from the background section, in existing vehicle front combination lamps, the lighting function and the signal function are basically separate viewing surfaces. This is because the light path design of the signal light can easily affect the light path of the lighting lamp, thereby affecting the lighting pattern. However, the vehicle front combination lamp provided in this application embodiment overcomes the problem that the light path of the signal light can easily affect the light path of the lighting lamp, thereby affecting the lighting pattern. By integrating the signal light and the lighting lamp together and sharing the inner lamp cover 10, the feasibility of the signal light can be ensured without affecting the lighting performance.

[0049] Figure 6 The diagram above shows a regulatory distribution diagram (top) and a lighting diagram (bottom) of the low beam pattern emitted by a vehicle front combination lamp provided in this application embodiment. It can be seen that the low beam pattern emitted by the vehicle front combination lamp provided in this application embodiment meets the regulatory requirements.

[0050] As can be seen from the above analysis, the vehicle front combination lamp provided in this application integrates the signal lamp and the headlight together, sharing the inner lamp cover 10. This ensures the feasibility of the signal lamp without affecting the lighting performance. Furthermore, the sharing of the inner lamp cover between the headlight and signal lamp paths facilitates a compact design for the vehicle front combination lamp, providing new directions and possibilities for its design and allowing for a more novel and unique lamp style. In addition, the first optical surface S1 of the inner lamp cover 10 is designed to reflect the signal lamp light beams by total internal reflection and then emit them in a directional manner, which can also improve the emission efficiency of the signal lamp.

[0051] Optionally, the first light source 30 can be an LED light source, which is soldered onto a PCB circuit board, and the PCB circuit board drives the LED light source to emit light. It is understood that LED light sources, as lighting sources, have advantages such as energy saving, environmental friendliness, long lifespan, and high brightness. Other optional features include halogen lamps, xenon lamps, or laser headlights, etc., which are not limited in this application.

[0052] As previously known, the light emitted by the second light source 40 is arranged along the third direction Z (i.e., the left-right direction of the vehicle) and points towards the bottom end face 13 of the inner lamp cover 10, so that it can enter the inner lamp cover 10 from the bottom end face 13 and then undergo total internal reflection by the first optical surface S1. Based on this, optionally, in some embodiments of this application, such as Figure 2 and Figure 3 As shown, the second light source 40 includes an LED light source 41 and a light guide structure 42. The light guide structure 42 extends along the third direction Z (i.e., the left-right direction of the vehicle). The LED light source 41 is located at one end of the light guide structure 42. The light emitted by the LED light source 41 enters the light guide structure 42 and, after passing through the light guide structure 42, forms light rays arranged along the third direction Z and pointing towards the bottom end face 13 of the inner lamp cover 10. At this time, the light guide structure 42 can be regarded as a line light source extending along the third direction Z. It can be understood that the LED light source 41 is soldered on the PCB circuit board, and the PCB circuit board drives the LED light source 41 to emit light.

[0053] Alternatively, in some embodiments of this application, the second light source 40 may also be a line light source or a surface light source extending along the third direction Z, thereby emitting light arranged along the third direction Z and pointing towards the bottom end face 13 of the inner lampshade 10.

[0054] Alternatively, in some embodiments of this application, the second light source 40 may also include a plurality of point light sources arranged along the third direction Z, thereby emitting light arranged along the third direction Z and pointing towards the bottom end face 13 of the inner lampshade 10.

[0055] However, it is understandable that compared to the second light source 40 which includes multiple point light sources arranged along the third direction Z, the second light source 40 includes an LED light source 41 and a light guide structure 42 extending along the third direction Z, and the second light source is a line light source or a surface light source extending along the third direction Z. All of these factors will make the light emitted by the second light source 40 pointing to the bottom end face 13 of the inner lamp cover 10 more uniformly arranged along the third direction Z.

[0056] Regardless of whether the second light source 40 comprises a plurality of point light sources arranged along the third direction Z, or the second light source 40 comprises an LED light source 41 and a light guide structure 42 extending along the third direction Z, or the second light source 40 is a line light source or a surface light source extending along the third direction Z, further optionally, in some embodiments of this application, such as Figure 7 As shown, Figure 7 This illustration shows a partially enlarged schematic diagram of the inner lamp cover 10 in a vehicle front combination lamp according to an embodiment of this application. It can be seen that the bottom end face 13 of the inner lamp cover 10 includes multiple patterned structures R1. The patterned structures R1 are used to diffuse light emitted from the second light source 40, arranged along the third direction Z and pointing towards the bottom end face 13 of the inner lamp cover 10, along the third direction Z. This arrangement allows the light incident on the inner lamp cover 10 from the bottom end face 13 to be more evenly distributed along the third direction Z, thereby resulting in a more uniform illumination effect of the signal light. In particular, when the second light source 40 includes multiple point light sources arranged along the third direction Z, the light emitted from these multiple point light sources and incident on the inner lamp cover 10 from the bottom end face 13 to be more evenly distributed along the third direction Z, further resulting in a more uniform illumination effect of the signal light.

[0057] Optionally, the bottom end face 13 of the inner lamp cover 10 can be a flat surface or a curved surface, depending on the situation.

[0058] Optionally, the pattern structure R1 on the bottom end face 13 of the inner lampshade 10 can be a recessed structure or a raised structure.

[0059] Optionally, the pattern structure R1 of the bottom end face 13 of the inner lampshade 10 can be striped, corn kernel-shaped, or other shapes.

[0060] Figure 8 It shows Figure 1 Another enlarged partial schematic diagram of the portion with a groove T1 on the first surface 11 of the inner lampshade 10, as shown below. Figure 8As shown, optionally, in some embodiments of this application, on the first surface 11 of the inner lampshade 10, a plurality of grooves T1 are arranged in multiple rows along the third direction Z, and each row of grooves T1 is arranged along the second direction Y; along the direction P away from the bottom end face 13 of the inner lampshade 10, the area of ​​the first optical surface S1 of each row of grooves T1 gradually increases; specifically, since the first optical surface S1 is a side wall surface of the groove T1, the depth of each row of grooves T1 can be gradually increased from shallow to deep along the direction P away from the bottom end face 13 of the inner lampshade 10, so that the area of ​​the first optical surface S1 of each row of grooves T1 gradually increases.

[0061] With this configuration, the light emitted by the second light source 40 and incident from the bottom end face 13 of the inner lamp cover 10 first passes through the smaller first optical surface S1. As a result, some of the light is totally reflected by the smaller first optical surface S1, while other light can be incident on the larger first optical surface S1 further away. This ensures that the first optical surfaces S1 of each row of grooves T1 arranged along the second direction Y can receive the signal light and perform total reflection on the signal light.

[0062] Furthermore, the first optical surface S1 closer to the bottom end face 13 of the inner lamp cover 10 receives relatively more light, while the first optical surface S1 farther from the bottom end face 13 of the inner lamp cover 10 receives relatively less light. Therefore, the area of ​​the first optical surface S1 of each row of grooves T1 is gradually increased along the direction P away from the bottom end face 13 of the inner lamp cover 10, which ultimately makes the signal light illumination effect better and the illumination more uniform.

[0063] Further optional, in some embodiments of this application, such as Figure 8 As shown, along the second direction Y, adjacent rows of grooves T1 do not overlap at least partially. That is, along the second direction Y, adjacent rows of grooves T1 are staggered. With this arrangement, the area with grooves T1 is provided on the first surface 11 of the inner lamp cover 10. Each groove T1 is evenly arranged, and the first optical surface S1 of each groove T1 is also evenly arranged, which makes the signal light illumination effect better and the illumination more uniform.

[0064] Accordingly, this application also provides a vehicle that includes the vehicle front combination lamp provided in any of the above embodiments. Since the vehicle front combination lamp has been described in detail in the foregoing embodiments, it will not be repeated here.

[0065] In summary, in the vehicle front combination lamp and vehicle provided in this application embodiment, the first light source 30, the reflector 20, and the inner lamp cover 10 combine to form a lighting lamp, and the second light source 40 and the inner lamp cover 10 combine to form a signal lamp. That is, the lighting lamp path and the signal lamp path share the inner lamp cover. The inner lamp cover 10 includes a first surface 11 and a second surface 12 arranged opposite to each other in the vehicle's front-rear direction, and a bottom end face 13 and a top end face 14 arranged opposite to each other in the vehicle's vertical direction. The bottom end face 13 is closer to the ground than the top end face 14. The first surface 11 of the inner lamp cover 10 is provided with a plurality of grooves T1, and the sidewall of the groove T1 includes a first optical surface S1. With this configuration, for the lighting lamp, the light emitted by the first light source 30 passes through the reflector 20. After reflection, at least part of the reflected light is incident on the first optical surface S1 of the first surface 11 of the inner lamp cover 10. After refraction by the first optical surface S1, it is emitted from the second surface 12 of the inner lamp cover 10, forming part of the illumination light pattern. Together with the light emitted by the first light source 30 after being reflected by the reflector 20 and then emitted through the non-recessed part of the inner lamp cover 10, the illumination light pattern is formed. The illumination light pattern includes a low beam pattern and / or a high beam pattern. For the signal light, the light emitted by the second light source 40 is arranged along the left and right direction of the vehicle and is incident on the inner lamp cover 10 from the bottom end face 13. After total internal reflection by the first optical surface S1 of the inner lamp cover 10, it is emitted from the second surface 12 of the inner lamp cover 10, forming the signal light emission light. In this way, the vehicle's front combination lamp can ensure the feasibility of signal lights without affecting the lighting performance. Moreover, the lighting light path and the signal light path share the same inner lamp cover, which is conducive to the compact shape design of the vehicle's front combination lamp and provides new directions and new possibilities for the shape design of the vehicle's front combination lamp, making the lamp style more novel and unique. Furthermore, the first optical surface S1 of the inner lamp cover 10 is designed to reflect the signal light light in a total reflection and then emit it in a directional manner, which can also improve the emission efficiency of the signal light.

[0066] Furthermore, the bottom end face 13 of the inner lamp cover 10 may include multiple patterned structures R1. The patterned structures R1 are used to diffuse the light emitted by the second light source 40, which is arranged along the third direction Z and points towards the bottom end face 13 of the inner lamp cover 10, along the third direction Z. This arrangement can make the light incident on the inner lamp cover 10 from the bottom end face 13 of the inner lamp cover 10 more evenly distributed along the third direction Z, thereby making the lighting effect of the signal light more uniform.

[0067] Furthermore, on the first surface 11 of the inner lamp cover 10, multiple grooves T1 are arranged in multiple rows along the third direction Z, and each row of grooves T1 is arranged along the second direction Y; along the direction P away from the bottom end face 13 of the inner lamp cover 10, the area of ​​the first optical surface S1 of each row of grooves T1 gradually increases, and along the second direction Y, adjacent rows of grooves T1 can at least partially not overlap, thus making the signal light illumination effect better and the illumination more uniform.
