Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to an automotive lighting fixture and a vehicle using the same lighting fixture. Background Technology

[0002] With the development of automotive lighting technology and the diversification of automotive headlight designs, users have placed higher demands on the performance of automotive headlights.

[0003] Currently, vehicle lights mainly serve the purpose of nighttime illumination, and their performance primarily focuses on road lighting effects. When the signal lights inside the vehicle lights are on, the lighting modules inside the lights are not lit. The appearance of the lighting modules cannot match the light-emitting area of ​​the signal lights, making it impossible to achieve a scenario where the lighting modules light up simultaneously with the signal lights, thus limiting the flexibility of vehicle light design.

[0004] In related technologies, two light sources are installed inside the headlight. One light source is used to meet nighttime lighting needs, while the other light source can be lit simultaneously with the signal lights to meet the headlight's design requirements. However, adding a light source inside the headlight increases its luminous power, making heat dissipation more difficult. Utility Model Content

[0005] In view of this, embodiments of this application provide a vehicle lamp and a vehicle to solve the technical problem of difficult heat dissipation of vehicle lamps.

[0006] In a first aspect, this application provides a vehicle light, comprising: First radiator; The second radiator is connected to the first radiator; A first light panel is installed between the first and second heat sinks and is in thermal contact with both the first and second heat sinks; and The second lamp panel is disposed on the second heat sink and is in thermal contact with the second heat sink.

[0007] In this way, when assembling the headlights, the first light panel can be installed on the first radiator, and the second light panel can be installed on the second radiator. Then the second radiator can be installed on the first radiator. The first light panel is located between the first radiator and the second radiator, and the first light panel is in thermally conductive contact with both the first radiator and the second radiator, making it very convenient to assemble the headlights together.

[0008] When the first lamp panel is lit, the first and second radiators can absorb the heat of the first lamp panel simultaneously, improving the heat dissipation efficiency of the first lamp panel. By using the first and second radiators together to dissipate heat for the first lamp panel, the heat dissipation requirements of the first lamp panel are met, while the volume of the first and second radiators can be effectively reduced, avoiding an increase in the overall size of the headlight due to excessively large radiator size.

[0009] Understandably, the second lamp panel only needs to meet the design requirements of the headlights. The heat generated when the second lamp panel is lit is less than the heat generated when the first lamp panel is lit. The second lamp panel is placed on the second radiator. When the second lamp panel is lit at the same time as the signal light, the second radiator dissipates heat for the second lamp panel, which can meet the heat dissipation requirements of the second lamp panel.

[0010] As an optional implementation, the first heat sink has a first heat dissipation surface, the second heat sink has a second heat dissipation surface, the second heat dissipation surface is disposed facing the first heat dissipation surface, and there is a gap between the second heat dissipation surface and the first heat dissipation surface; The first lamp panel is disposed between the first heat dissipation surface and the second heat dissipation surface, and is in thermal contact with both the first heat dissipation surface and the second heat dissipation surface.

[0011] Thus, when the first lamp board is lit, it can transfer heat to the first and second heat sinks through two independent heat conduction interfaces, forming a mechanism of parallel heat dissipation through two heat dissipation paths. The two heat dissipation paths work simultaneously without interfering with each other, which not only increases the heat dissipation surface area but also reduces the single-path thermal resistance, thereby further improving the heat dissipation efficiency of the first lamp board.

[0012] As an optional implementation, the second heat dissipation surface is provided with a heat-conducting layer, which is in contact with the first lamp plate.

[0013] In this way, the second heat dissipation surface makes thermal contact with the first lamp board through the heat-conducting layer. As a heat conduction medium, the heat-conducting layer can avoid direct contact between the second heat dissipation surface and the first lamp board, effectively preventing damage to the first lamp board caused by mechanical collision during installation. The heat-conducting layer itself has elastic buffering properties. During the process of assembling the second heat sink to the first heat sink, the heat-conducting layer can absorb assembly stress and reduce the potential damage to the first lamp board caused by vibration and impact.

[0014] As an optional implementation, the second heat sink also has a third heat dissipation surface, which is located on a different side from the second heat dissipation surface, and the second lamp plate is disposed on the third heat dissipation surface.

[0015] In this way, the second lamp board can exchange heat with the third heat dissipation surface. When the second lamp board is lit, the heat on the second lamp board can be transferred to the second heat sink through the third heat dissipation surface, and then dissipated to the external environment through the second heat sink, thereby improving the heat dissipation efficiency of the second lamp board. Since the third heat dissipation surface and the second heat dissipation surface are located on different sides of the second heat sink, the thermal resistance between the second heat dissipation surface and the third heat dissipation surface can be increased, preventing the heat from the second heat dissipation surface from interfering with the third heat dissipation surface.

[0016] As an optional implementation, the first heat sink has at least one of a slot and a buckle, and the second heat sink has at least the other of the slot and the buckle, wherein the buckle engages with the corresponding slot.

[0017] In this way, when assembling the headlights, the clips can be engaged in the slots, allowing the second radiator to be quickly assembled with the first radiator, reducing the difficulty of assembling the headlights.

[0018] As an optional implementation, the vehicle light further includes a connector, wherein the first radiator has a first connection hole and the second radiator has a second connection hole, and the connector passes through the first connection hole and the second connection hole to connect the first radiator and the second radiator.

[0019] In this way, the connector can fix the second heat sink to the first heat sink, so that the second heat sink can be stably fixed to the first heat sink.

[0020] As an optional implementation, a receiving cavity is provided between the first heat sink and the second heat sink, and the first lamp panel has a light source, with the light source of the first lamp panel located within the receiving cavity; Wherein, at least one of the first heat sink and the second heat sink has a heat dissipation hole, and the heat dissipation hole is in communication with the receiving cavity.

[0021] Thus, the receiving cavity is located between the first heat sink and the second heat sink, and the receiving cavity is connected to the gap between the first heat sink surface and the second heat sink surface. The first lamp board is located in the gap, and the light source on the first lamp board is located in the receiving cavity. The receiving cavity has enough space for the light source to emit light, thereby preventing the first heat sink and the second heat sink from obstructing the propagation of light.

[0022] Furthermore, the heat dissipation holes are connected to the housing cavity. When the light source emits light, the temperature inside the housing cavity rises. Multiple heat dissipation holes can improve the heat dissipation efficiency of the housing cavity, thereby preventing the temperature of the housing cavity from becoming too high and further improving the heat dissipation efficiency of the first lamp board.

[0023] As an optional implementation, the vehicle light further includes: A first lens is mounted on the first heat sink, and the first lens is at least partially located between the first heat sink and the second heat sink. The first lens covers the light source on the first lamp panel, and the first lens is used to allow light emitted from the first lamp panel to pass through. The second lens is mounted on the second heat sink and covers the light source on the second lamp panel. The second lens is located between the first lens and the second lamp panel. The second lens and the first lens are used to allow light emitted from the second lamp panel to pass through.

[0024] Thus, by placing a portion of the first lens between the first radiator and the second radiator, the first lens can be installed compactly. By placing the second lens between the second lamp plate and another portion of the first lens, the second lens can also be installed compactly. This allows the first lens, the second lens, the first radiator, and the second radiator to be assembled together compactly, further reducing the overall size of the vehicle headlight.

[0025] As an alternative implementation, the first lens has a clearance groove, and the second lens is at least partially located within the clearance groove.

[0026] Thus, when the first lens and the second lens are assembled together in the headlight, the clearance groove can prevent the first lens and the second lens from interfering with each other, prevent the first lens and the second lens from colliding, and provide space for the installation of the second lens, further reducing the overall size of the headlight.

[0027] Secondly, this application also provides a vehicle, including a body and the aforementioned vehicle lights, the vehicle lights being mounted on the body.

[0028] The vehicle provided in this application, by adopting the aforementioned headlights, has low manufacturing costs and good performance. Attached Figure Description

[0031] 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.

[0032] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] Currently, the vehicle headlight 100 mainly serves as nighttime illumination, and its performance focuses primarily on road lighting effects. When the signal lights inside the vehicle headlight 100 are lit, the lighting module inside the vehicle headlight 100 is not lit. The appearance of the lighting module cannot match the light-emitting area of ​​the signal lights, making it impossible to achieve a scenario where the lighting module lights up simultaneously with the signal lights, thus limiting the flexibility of the vehicle headlight 100's design.

[0034] In related technologies, two light sources are installed inside the headlight 100. One light source is used to meet the needs of nighttime illumination, and the other light source can be lit simultaneously with the signal lights to meet the design requirements of the headlight 100. However, adding a light source inside the headlight 100 will increase the luminous power of the headlight 100, making heat dissipation difficult.

[0035] Based on this, this application provides a vehicle lamp 100 and a vehicle. The first lamp panel 30 in the vehicle lamp 100 is used to meet nighttime lighting needs, and the second lamp panel 40 can be illuminated simultaneously with the signal lights to meet the design requirements of the vehicle lamp 100. When the first lamp panel 30 is illuminated, the first heat sink 10 and the second heat sink 20 can simultaneously absorb the heat from the first lamp panel 30, improving the heat dissipation efficiency of the first lamp panel 30. By having the first heat sink 10 and the second heat sink 20 jointly dissipate heat for the first lamp panel 30, the heat dissipation requirements of the first lamp panel 30 are met, while also effectively reducing the volume of the first heat sink 10 and the second heat sink 20, avoiding an increase in the overall volume of the vehicle lamp 100 due to excessively large heat sink sizes. Furthermore, by placing the second lamp panel 40 on the second heat sink 20, when the second lamp panel 40 is illuminated simultaneously with the signal lights, the second heat sink 20 dissipates heat for the second lamp panel 40, thus meeting the heat dissipation requirements of the second lamp panel 40.

[0036] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0037] Please see Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of the vehicle headlight provided in an embodiment of this application. Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure at point AA. Figure 3 This is a schematic diagram of the structure of the first lamp board, the first lens mounting, and the first heat sink provided in an embodiment of this application. Figure 4 This is a schematic diagram of the structure of the second lamp board, the second lens mounting, and the second heat sink provided in the embodiments of this application.

[0038] As shown in the figure, this embodiment provides a vehicle light 100, which includes a first radiator 10, a second radiator 20, a first lamp plate 30, and a second lamp plate 40. The first radiator 10 is connected to the second radiator 20. The first lamp plate 30 is installed between the first radiator 10 and the second radiator 20, and the first lamp plate 30 is in thermally conductive contact with both the first radiator 10 and the second radiator 20. The second lamp plate 40 is disposed on the second radiator 20, and the second lamp plate 40 is in thermally conductive contact with the second radiator 20.

[0039] Thus, when assembling the headlight 100, the first lamp plate 30 can be installed on the first radiator 10, and the second lamp plate 40 can be installed on the second radiator 20. Then, the second radiator 20 can be installed on the first radiator 10. The first lamp plate 30 is located between the first radiator 10 and the second radiator 20, and the first lamp plate 30 is in thermally conductive contact with the first radiator 10 and the second radiator 20, making it very convenient to assemble the headlight 100 together.

[0040] In this embodiment, the first lamp panel 30 is used to meet the nighttime lighting requirements, and the second lamp panel 40 can be lit simultaneously with the signal lights to meet the design requirements of the vehicle headlight 100. When the first lamp panel 30 is lit, the first radiator 10 and the second radiator 20 can absorb the heat of the first lamp panel 30 simultaneously, improving the heat dissipation efficiency of the first lamp panel 30. By having the first radiator 10 and the second radiator 20 work together to dissipate heat from the first lamp panel 30, the heat dissipation requirements of the first lamp panel 30 are met, while the volume of the first radiator 10 and the second radiator 20 can be effectively reduced, avoiding an increase in the overall volume of the vehicle headlight 100 due to excessively large radiator size.

[0041] Understandably, the second lamp panel 40 only needs to meet the design requirements of the headlight 100. The heat generated when the second lamp panel 40 is lit is less than the heat generated when the first lamp panel 30 is lit. The second lamp panel 40 is placed on the second radiator 20. When the second lamp panel 40 is lit at the same time as the signal light, the second radiator 20 dissipates heat from the second lamp panel 40, which can meet the heat dissipation requirements of the second lamp panel 40.

[0042] Optionally, both the first radiator 10 and the second radiator 20 are finned radiators, that is, both the first radiator 10 and the second radiator 20 have multiple fins. The fins can increase the heat dissipation surface area of ​​the first radiator 10 and the second radiator 20, thereby significantly improving the heat dissipation efficiency of the first radiator 10 and the second radiator 20.

[0043] To further improve the heat dissipation efficiency of the first lamp board 30, please refer to [further details]. Figure 5 and Figure 6 , Figure 5 This is a three-dimensional structural diagram of the first heat sink provided in an embodiment of this application. Figure 6 This is a three-dimensional structural diagram of the second heat sink provided in an embodiment of this application.

[0044] In some embodiments, the first heat sink 10 has a first heat dissipation surface 11, the second heat sink 20 has a second heat dissipation surface 21, the second heat dissipation surface 21 is disposed facing the first heat dissipation surface 11, and there is a gap between the second heat dissipation surface 21 and the first heat dissipation surface 11. The first lamp plate 30 is disposed between the first heat dissipation surface 11 and the second heat dissipation surface 21, and the first lamp plate 30 is in thermally conductive contact with both the first heat dissipation surface 11 and the second heat dissipation surface 21.

[0045] Thus, the first heat dissipation surface 11 and the second heat dissipation surface 21 are located on opposite sides of the first lamp panel 30, wherein the first heat dissipation surface 11 is in thermal contact with the first side of the first lamp panel 30, and the second heat dissipation surface 21 is in thermal contact with the second side of the first lamp panel 30. The first side and the second side are opposite sides of the first lamp panel 30, forming a double-sided clamping heat dissipation layout.

[0046] When the first lamp panel 30 is lit, the first heat dissipation surface 11 exchanges heat with the first side surface. The heat on the first lamp panel 30 is transferred to the first heat sink 10 through the first side surface and the first heat dissipation surface 11, and then dissipated to the external environment through the first heat sink 10. At the same time, the second heat dissipation surface 21 exchanges heat with the second side surface. The heat on the first lamp panel 30 is transferred to the second heat sink 20 through the second side surface and the second heat dissipation surface 21, and then dissipated to the external environment through the second heat sink. This allows the first lamp panel 30 to transfer heat to the first heat sink 10 and the second heat sink 20 through two independent heat conduction interfaces (i.e., the first side surface and the second side surface), forming a dual heat dissipation path parallel heat dissipation mechanism. The two heat dissipation paths work simultaneously and do not interfere with each other, which not only expands the heat dissipation surface area but also reduces the single-path thermal resistance, thereby further improving the heat dissipation efficiency of the first lamp panel 30.

[0047] In this embodiment, when the second radiator 20 is installed on the first radiator 10, there is a gap between the first heat dissipation surface 11 and the second heat dissipation surface 21. The first lamp plate 30 is located in the gap, and the first side of the first lamp plate 30 is in contact with the first heat dissipation surface 11, and the second side of the first lamp plate 30 is in contact with the second heat dissipation surface 21. This allows the first radiator 10, the first lamp plate 30, and the second radiator 20 to be installed together compactly, keeping the overall structure of the vehicle lamp 100 compact and further reducing the size of the vehicle lamp 100.

[0048] In some embodiments, the second heat dissipation surface 21 is provided with a heat-conducting layer, which is in contact with the first lamp plate 30.

[0049] Thus, the second heat dissipation surface 21 makes thermal contact with the first lamp panel 30 through the heat-conducting layer. As a heat conduction medium, the heat-conducting layer can prevent the second heat dissipation surface 21 from directly contacting the first lamp panel 30, effectively preventing damage to the first lamp panel 30 caused by mechanical collision during installation. The heat-conducting layer itself has elastic buffering properties. During the process of assembling the second heat sink 20 to the first heat sink 10, the heat-conducting layer can absorb assembly stress and reduce the potential damage to the first lamp panel 30 caused by vibration and impact.

[0050] Specifically, when the second heat sink 20 is fixed to the first heat sink 10 by fasteners, the heat-conducting layer can adaptively fill the micro gaps in the contact surface. While ensuring that the heat transfer path between the first lamp plate 30 and the second heat sink 20 is unobstructed, the heat-conducting layer forms a flexible buffer layer, which effectively suppresses mechanical stress caused by assembly errors or differences in thermal expansion coefficients, and ultimately achieves dual optimization of heat dissipation function and structural protection.

[0051] Alternatively, the thermal conductive layer can be a material with good thermal conductivity, such as thermal grease, thermal pad, thermal adhesive, metal thermal pad (such as copper or aluminum), or phase change material.

[0052] Please see Figure 2 , Figure 4 and Figure 6 In some embodiments, the second heat sink 20 also has a third heat dissipation surface 22, which is located on different sides from the second heat dissipation surface 21, and the second lamp plate 40 is disposed on the third heat dissipation surface 22.

[0053] In this way, the second lamp panel 40 can exchange heat with the third heat dissipation surface 22. When the second lamp panel 40 is lit, the heat on the second lamp panel 40 can be transferred to the second heat sink 20 through the third heat dissipation surface 22, and then dissipated to the external environment through the second heat sink 20, thereby improving the heat dissipation efficiency of the second lamp panel 40. Since the third heat dissipation surface 22 and the second heat dissipation surface 21 are located on different sides of the second heat sink 20, the thermal resistance between the second heat dissipation surface 21 and the third heat dissipation surface 22 can be increased, preventing the heat from the second heat dissipation surface 21 from interfering with the third heat dissipation surface 22.

[0054] Please see Figure 3 and Figure 4 In some embodiments, the first heat sink 10 has at least one of a slot 23 and a latch 12, and the second heat sink 20 has at least the other of a slot 23 and a latch 12, with the latch 12 engaging with the corresponding slot 23.

[0055] In this embodiment, the outer surface of the first radiator 10 is recessed to form a slot 23, and the outer surface of the second radiator 20 is protruded to form a buckle 12. When assembling the headlight 100, the buckle 12 on the second radiator 20 can be snapped into the slot 23 of the first radiator 10, so that the second radiator 20 and the first radiator 10 can be quickly assembled together, reducing the assembly difficulty of the headlight 100.

[0056] In other embodiments, the outer surface of the first radiator 10 protrudes to form a buckle 12, and the outer surface of the second radiator 20 is recessed to form a groove 23. When assembling the vehicle light 100, the first radiator 10 and the second radiator 20 can be quickly assembled by snapping the buckle 12 into the groove 23, which can also reduce the assembly difficulty of the vehicle light 100.

[0057] Alternatively, both the first radiator 10 and the second radiator 20 may have slots 23 and clips 12. When assembling the headlight 100, the first radiator 10 and the second radiator 20 may be quickly assembled by engaging the clips 12 on the first radiator 10 with the slots 23 on the second radiator 20, and by engaging the slots 23 on the first radiator 10 with the clips 12 on the second radiator 20. This reduces the difficulty of assembling the headlight 100 and makes the first radiator 10 and the second radiator 20 more securely assembled.

[0058] Please see Figure 3and Figure 4 In some embodiments, the headlight 100 further includes a connector 50, the first radiator 10 has a first connection hole 13, the second radiator 20 has a second connection hole 24, and the connector 50 passes through the first connection hole 13 and the second connection hole 24 to connect the first radiator 10 and the second radiator 20.

[0059] Optionally, the connector 50 can be a bolt, the first connecting hole 13 is a threaded hole, and the second connecting hole 24 is a through hole. The connector 50 is inserted into the first connecting hole 13 and the second connecting hole 24. The connector 50 is threadedly engaged with the first connecting hole 13. The connector 50 can fix the second radiator 20 onto the first radiator 10, so that the second radiator 20 can be stably fixed onto the first radiator 10.

[0060] Please see Figures 2 to 4 In some embodiments, a receiving cavity 101 is provided between the first heat sink 10 and the second heat sink 20, and the first lamp plate 30 has a light source. The light source of the first lamp plate 30 is located in the receiving cavity 101. At least one of the first heat sink 10 and the second heat sink 20 has a heat dissipation hole 25, which is connected to the receiving cavity 101.

[0061] It should be noted that the gap between the first lamp panel 30 and the first heat dissipation surface 11 and the second heat dissipation surface 21 can improve the heat dissipation efficiency of the first lamp panel 30, but it is necessary to ensure that the first heat dissipation surface 11 and the second heat dissipation surface 21 do not obstruct the first lamp panel 30 from providing nighttime illumination.

[0062] In this embodiment, the receiving cavity 101 is located between the first heat sink 10 and the second heat sink 20, and the receiving cavity 101 is connected to the gap between the first heat dissipation surface 11 and the second heat dissipation surface 21. The first lamp board 30 is located in the gap, and the light source on the first lamp board 30 is located in the receiving cavity 101. The receiving cavity 101 has enough space for the light source to emit light, thereby preventing the first heat sink 10 and the second heat sink 20 from obstructing the propagation of light.

[0063] Optionally, the second heat sink 20 has multiple heat dissipation holes 25, all of which are connected to the receiving cavity 101. When the light source emits light, the temperature inside the receiving cavity 101 rises. The multiple heat dissipation holes 25 can increase the heat dissipation efficiency of the receiving cavity 101, thereby preventing the temperature of the receiving cavity 101 from becoming too high and further improving the heat dissipation efficiency of the first lamp board 30.

[0064] Alternatively, the first radiator 10 may be provided with multiple heat dissipation holes 25, or both the first radiator 10 and the second radiator 20 may be provided with heat dissipation holes 25. The position and number of heat dissipation holes 25 can be set according to the actual situation.

[0065] Please see Figure 2 In some embodiments, the headlight 100 further includes a first lens 60 and a second lens 70. The first lens 60 is mounted on the first radiator 10 and is at least partially located between the first radiator 10 and the second radiator 20. The first lens 60 covers the light source of the first lamp panel 30 and is used to allow light emitted from the first lamp panel 30 to pass through. The second lens 70 is mounted on the second radiator 20 and covers the light source on the second lamp panel 40. The second lens 70 is located between the first lens 60 and the second lamp panel 40. The second lens 70 and the first lens 60 are used to allow light emitted from the second lamp panel 40 to pass through.

[0066] Optionally, the first lens 60 may include an inner lens unit and an outer lens unit. The inner lens unit is located between the first radiator 10 and the second radiator 20, that is, the inner lens unit is located in the receiving cavity 101 and covers the light source of the first lamp panel 30. The outer lens unit is located at the light outlet of the vehicle lamp 100. When the light source of the first lamp panel 30 emits light, the light is converged into the first lens through the light-incident surface of the inner lens unit. After reflection, the converged light is emitted outward from the light-outceasing surface of the outer lens unit to meet the lighting needs of the vehicle lamp 100 at night.

[0067] The second lens 70 is mounted on the second radiator 20 and covers the light source of the second lamp panel 40. The second lens 70 is located between the second lamp panel 40 and the outer lens unit. When the second lamp panel 40 is lit at the same time as the signal light, the light emitted by the second lamp panel 40 passes through the light-incident surface of the second lens 70 and is emitted outward from the light-outceasing surface of the outer lens unit to meet the design requirements of the vehicle lamp 100.

[0068] Thus, by placing the inner lens unit of the first lens 60 between the first radiator 10 and the second radiator 20, the first lens 60 can be installed compactly. By placing the second lens 70 between the second lamp plate 40 and the outer lens unit of the first lens 60, the second lens 70 can be installed compactly. This allows the first lens 60, the second lens 70, the first radiator 10, and the second radiator 20 to be assembled together compactly, further reducing the overall size of the vehicle lamp 100.

[0069] In addition, the first radiator 10 is at least partially supported on the outer lens unit of the first lens 60, so that the first radiator 10 can fully contact the first lens 60, thereby the first radiator 10 can dissipate heat for the first lens 60 and further improve the heat dissipation efficiency of the vehicle lamp.

[0070] In some embodiments, the first lens 60 is integrally formed, which can further reduce the overall size of the headlight 100.

[0071] Please see Figure 2 and Figure 3 In some embodiments, the first lens 60 has a clearance groove 601, and the second lens 70 is at least partially located within the clearance groove 601.

[0072] Thus, when the first lens 60 and the second lens 70 are assembled together in the headlight 100, the clearance groove 601 can prevent the first lens 60 and the second lens 70 from interfering with each other, prevent the first lens 60 and the second lens 70 from colliding, and the clearance groove 601 can provide space for the installation of the second lens 70, further reducing the overall volume of the headlight 100.

[0073] It should be noted that when setting the clearance groove 601, the clearance groove 601 should not obstruct the normal propagation of light inside the first lens 60, and the clearance groove 601 needs to be set in a reasonable position.
