Description

Technical Field

[0001] This application relates to the field of vehicle lighting, and more particularly to a lighting assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, as the development of vehicle electrification and intelligence drives the evolution of headlights towards thinner and narrower shapes, the traditional structures currently commonly used are large in size and weight, and have complex cost and manufacturing processes. Therefore, how to reduce the size of vehicle lights has become the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to at least address one of the technical problems existing in the prior art. Therefore, one objective of this application is to provide a lighting assembly for vehicles that can reduce the size of vehicle lights.

[0004] This application also proposes vehicles using the aforementioned lighting components.

[0005] A lighting assembly for a vehicle according to an embodiment of this application includes: a lamp housing, a heat dissipation cavity formed at the rear of the lamp housing, and a light emission channel communicating with the heat dissipation cavity at the front of the lamp housing; an optical lens, at least a portion of which is disposed within the light emission channel, the optical lens having a first light-injecting surface and a second light-injecting surface spaced apart in the height direction on a side facing the heat dissipation cavity; a signal light assembly, disposed within the heat dissipation cavity, the signal light assembly having a first light-emitting end and being directly opposite the first light-injecting surface; and a lighting assembly, disposed within the heat dissipation cavity, the lighting assembly having a second light-emitting end and being directly opposite the second light-injecting surface; wherein at least one of the first light-injecting surface and the second light-injecting surface in the optical lens is inclined in the direction toward the light emission channel.

[0006] The vehicle lighting assembly according to embodiments of this application achieves significant volume reduction through integrated design. The signal light and headlight assemblies are co-located in the heat dissipation cavity of the lamp housing, sharing a light emission channel. A single optical lens with dual light-intake surfaces spaced apart in the height direction adapts to the light-emitting ends of both types of components, eliminating the need for independent optical structures and significantly reducing space redundancy. At least one tilted light-intake surface of the lens optimizes the light incidence angle, ensuring efficient coupling of light from both types of light sources without increasing lens thickness or channel cross-sectional dimensions, avoiding size expansion caused by light path interference. Simultaneously, heat dissipation can be achieved within the heat dissipation cavity, reducing lamp weight, the number of parts and assembly steps, simplifying the process, and lowering costs. This aligns with the slim and compact design requirements of automobiles, ensuring both signal light and headlight functionality while maintaining lightweight structure and operational reliability.

[0007] According to some embodiments of this application, a lighting assembly for a vehicle includes a signal light assembly comprising: a signal light plate disposed in a heat dissipation cavity and spaced apart from a first light-incoming surface, wherein a signal light is disposed on the signal light plate facing the first light-incoming surface; and a first heat dissipation member disposed on the side of the signal light plate away from the first light-emitting end and extending obliquely in the height direction away from the light-emitting channel.

[0008] According to some embodiments of this application, a lighting assembly for a vehicle includes a signal light panel comprising: a first panel segment, which is directly opposite to a light emission channel and extends in the height direction, and a signal light is disposed on the first panel segment; a second panel segment, which is disposed at the lower end of the first panel segment and extends toward the rear, and the second panel segment is inclined downward in a direction away from the light emission channel; and a first heat sink is disposed on the first panel segment or the second panel segment.

[0009] According to some embodiments of the present application, the lighting assembly for a vehicle further includes a third section disposed at the rear end of the second section and attached to the lighting assembly.

[0010] According to some embodiments of this application, a lighting assembly for a vehicle has a first heat sink configured as a plurality of first fins, each first fin extending obliquely in a direction perpendicular to a second plate segment.

[0011] According to some embodiments of this application, a lighting assembly for a vehicle includes: a lighting panel disposed in a heat dissipation cavity and parallel to a second light-incoming surface, wherein a lighting lamp is disposed on the lighting panel facing the second light-incoming surface; and a second heat sink disposed on the side of the lighting panel away from the second light-emitting end.

[0012] According to some embodiments of this application, a lighting assembly for a vehicle has a heat-conducting plate disposed between the lighting panel and the second heat sink.

[0013] The lighting assembly for a vehicle according to some embodiments of this application further includes: a cooling fan disposed on one side of the lamp housing in the width direction and communicating with the heat dissipation cavity.

[0014] According to some embodiments of this application, a lighting assembly for a vehicle has a heat dissipation cavity having vents open at the top and / or bottom; it also includes a cooling fan disposed at the rear of the lamp housing and for discharging air toward the heat dissipation cavity.

[0015] The vehicle according to an embodiment of this application is briefly described below.

[0016] The vehicle according to the embodiments of this application includes the lighting components of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lighting components of any of the above embodiments, the reduction in the volume of the vehicle lighting components according to this application reduces the vehicle's installation space requirements, reserving more space for components at the front of the vehicle body, improving the layout flexibility of the vehicle chassis and front body, and conforming to the trend of thinner and narrower headlights, thus optimizing the overall aerodynamic design of the vehicle. The reduction in component weight directly reduces the vehicle's curb weight, reduces energy loss during driving, significantly improves the driving range for electric vehicles, and optimizes fuel economy for gasoline vehicles. In addition, the integration of the lighting components reduces the number of parts and assembly steps in the vehicle lighting system, shortens the vehicle's final assembly production cycle, and reduces the overall vehicle manufacturing cost. The reliability of the lighting, which is ensured by heat dissipation in the heat dissipation cavity, also indirectly reduces the frequency of lighting-related failures during vehicle after-sales maintenance, improving the overall durability of the vehicle.

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] The following is for reference. Figures 1-7 A lamp assembly 100 for a vehicle according to an embodiment of this application is described.

[0022] According to an embodiment of this application, a lighting assembly 100 for a vehicle includes a lamp housing 1, an optical lens 2, a signal light assembly 3, and a lighting assembly 4. The lamp housing 1 has a heat dissipation cavity 11 formed at its rear, and a light emission channel 12 communicating with the heat dissipation cavity 11 is provided at its front. At least a portion of the optical lens 2 is disposed within the light emission channel 12. The optical lens 2 has a first light-incoming surface 21 and a second light-incoming surface 22 spaced apart in the height direction on the side facing the heat dissipation cavity 11. The signal light assembly 3 is disposed within the heat dissipation cavity 11 and has a first light-emitting end 31 directly opposite the first light-incoming surface 21. The lighting assembly 4 is disposed within the heat dissipation cavity 11 and has a second light-emitting end 41 directly opposite the second light-incoming surface 22. At least one of the first light-incoming surface 21 and the second light-incoming surface 22 in the optical lens 2 is inclined in the direction facing the light emission channel 12.

[0023] It is understandable that the heat dissipation cavity 11 formed at the rear of the lamp housing 1 is interconnected with the light emission channel 12 at the front, allowing the signal light assembly 3 and the lighting assembly 4 to be jointly housed within the heat dissipation cavity 11. The two functional components do not require separate mounting cavities. The lateral arrangement space and longitudinal installation gap reserved for the two types of components in the traditional separate design are completely compressed, directly reducing the overall space occupied by the lamp through the centralized layout of the components. Simultaneously, the optical lens 2 is at least partially disposed within the light emission channel 12, and a first light-incoming surface 21 and a second light-incoming surface 22 are specifically formed at height intervals on the side facing the heat dissipation cavity 11. The first light-incoming surface 21 is directly opposite the first light-emitting end 31 of the signal light assembly 3, and the second light-incoming surface 22 is directly opposite the second light-emitting end 41 of the lighting assembly 4. This eliminates the need for separate optical lenses 2 and corresponding mounting structures for the signal light assembly 3 and the lighting assembly 4, avoiding the increased volume caused by the stacking of multiple optical components and significantly reducing the overall size of the optical system.

[0024] Furthermore, at least one of the first light-inlet surface 21 and the second light-inlet surface 22 in the optical lens 2 is inclined in the direction toward the light-out channel 12. Since the two types of components are placed in the same heat dissipation cavity 11 and share the same optical lens 2, if the light-inlet surface is set vertically, the light from the two types of light sources may cause path interference within the optical lens 2. To avoid interference, the height of the optical lens 2 or the cross-sectional size of the light-out channel 12 needs to be increased. However, the inclined light-inlet surface can adjust the incident angle of the light so that the light from the signal light component 3 and the light from the lighting component 4 form independent transmission paths that do not interfere with each other within the optical lens 2. Without increasing the thickness of the optical lens 2 or expanding the cross-sectional size of the light-out channel 12, it ensures that both types of light can be efficiently coupled into the optical lens 2 and achieve the preset light-out effect. From the perspective of optical path optimization, this further consolidates the reduction effect of the lamp body volume and achieves a balance between compact structure and optical performance.

[0025] Furthermore, the signal light assembly 3 and the lighting assembly 4 are both housed within the heat dissipation cavity 11, allowing heat to be dissipated within the cavity. This simplifies the heat dissipation path design, whereas traditional structures require separate heat dissipation paths and spaces for the two types of components. This centralized heat dissipation approach reduces the number of heat dissipation-related components, lowering the overall weight of the lamp and avoiding the extra space required by independent heat dissipation structures, indirectly contributing to the control of the lamp's volume. Simultaneously, the integrated layout of the components reduces the overall number of parts in the lamp, simplifying assembly processes during production, reducing process complexity and manufacturing costs. While achieving a significant reduction in lamp volume, it ensures the stable functionality of both the signal light 311 and the lighting assembly 411, balancing lightweight structure, simplified manufacturing process, and reliable operation.

[0026] In short, a significant reduction in size is achieved through integrated design. The signal light 311 and the lighting assembly 4 are housed together in the heat dissipation cavity 11 of the lamp housing 1, sharing the light emission channel 12. A single optical lens 2 with dual light-incoming surfaces spaced apart in the height direction adapts to the light emission ends of the two types of components respectively, eliminating the need for independent optical structures and greatly reducing space redundancy. The optical lens 2 has at least one tilted light-incoming surface, which optimizes the incident angle of light. Without increasing the thickness of the optical lens 2 or the cross-sectional size of the channel, it ensures efficient coupling of light from the two types of light sources and avoids size expansion caused by light path interference. At the same time, heat dissipation can be carried out within the heat dissipation cavity 11, reducing the weight of the lamp, reducing the number of parts and assembly processes, simplifying the process, reducing costs, and meeting the requirements of thin and narrow automotive shapes. While ensuring the functionality of the signal light 311 and the lighting assembly 411, it also takes into account structural lightweighting and reliability.

[0027] According to some embodiments of this application, a lighting assembly 100 for a vehicle includes a signal light assembly 3 comprising: a signal light plate 32 disposed in a heat dissipation cavity 11 and spaced apart from a first light-incoming surface 21, and a signal light 311 disposed on the signal light plate 32 facing the first light-incoming surface 21; and a first heat sink 33 disposed on the side of the signal light plate 32 away from the first light-emitting end 31 and extending obliquely in the height direction away from the light-emitting channel 12.

[0028] The signal light plate 32 is disposed within the heat dissipation cavity 11 and spaced apart from the first light-incoming surface 21, providing a propagation path for the light from the signal light 311. This allows the light to diffuse evenly within the space before incident on the first light-incoming surface 21. The design of the first light-incoming surface 21 achieves optical coupling while preventing light obstruction or heat conduction interference caused by direct contact between the signal light plate 32 and the optical lens 2, ensuring the stability of optical transmission. The first heat sink 33 is disposed on the side of the signal light plate 32 away from the first light-emitting end 31, preventing the heat sink from obstructing the light path of the signal light 311 and ensuring that the light does not affect the incident light onto the first light-incoming surface 21. Simultaneously, it can contact the core area of ​​the signal light plate 32 that generates heat, improving heat conduction efficiency.

[0029] The first heat sink 33 is inclined and extended away from the light emission channel 12 in the height direction, making full use of the space resources in the heat dissipation cavity 11. The extension in the height direction can effectively increase the heat dissipation area of ​​the heat sink and improve the heat dissipation efficiency to ensure the long-term stable operation of the signal light assembly 3. The inclined setting avoids structural interference between the first heat sink 33 and the lighting assembly 4 in the limited lateral space in the heat dissipation cavity 11. It does not require expanding the lateral size of the heat dissipation cavity 11 to avoid the components, thus maintaining the compact layout of the heat dissipation cavity 11, which meets the overall thin and narrow shape requirements of the lamp.

[0030] According to some embodiments of this application, a lighting assembly 100 for a vehicle includes a signal light panel 32 comprising: a first panel segment 321, which is directly opposite to the light emission channel 12 and extends in the height direction, and a signal light 311 is disposed on the first panel segment 321; a second panel segment 322, which is disposed at the lower end of the first panel segment 321 and extends toward the rear, and the second panel segment 322 is inclined downward in a direction away from the light emission channel 12; and a first heat sink 33 is disposed on the first panel segment 321 or the second panel segment 322.

[0031] The first plate segment 321 is directly opposite to the light-emitting channel 12 and extends along the height direction. The signal lamp 311 is set on the first plate segment 321 so that the installation position of the signal lamp 311 can be accurately aligned with the first light-inlet surface 21 of the optical lens 2. This ensures that the light emitted by the signal lamp 311 propagates in a straight line to the first light-inlet surface 21, reducing the loss and deviation of light during the propagation process, improving the optical coupling efficiency, and ensuring that the light output effect of the signal lamp 311 meets the preset requirements. At the same time, the extension design in the height direction is adapted to the arrangement range of the first light-inlet surface 21 of the optical lens 2, avoiding the waste of light caused by the deviation of the installation position of the signal lamp 311.

[0032] The second plate segment 322 is located at the lower end of the first plate segment 321 and extends towards the rear. It is inclined downward in a direction away from the light emission channel 12. The rearward extension allows the second plate segment 322 to make full use of the space behind the heat dissipation cavity 11, without occupying the critical optical space and installation space around the light emission channel 12 and near the first plate segment 321, thus avoiding interference with light propagation and the installation of other components. The downward inclination and the setting away from the light emission channel 12 can effectively avoid other components such as the lighting component 4 in the heat dissipation cavity 11. There is no need to reserve clearance by increasing the lateral width or vertical height of the heat dissipation cavity 11, thus maintaining the compact size of the heat dissipation cavity 11 to the maximum extent, which meets the needs of the thin and narrow shape evolution of vehicle lights.

[0033] The first heat sink 33 is disposed on the first plate segment 321 or the second plate segment 322. If the first heat sink 33 is installed on the first plate segment 321, it can directly fit the core heat-generating area where the signal light 311 is located, shortening the heat conduction path and quickly dissipating the heat generated when the signal light 311 is working. If it is installed on the second plate segment 322, the extension structure and tilt angle of the second plate segment 322 provide sufficient installation area for the heat sink, and the tilt direction is away from the light emission channel 12, so it will not block the light emission path of the signal light 311. At the same time, the rearward extension of the second plate segment 322 allows the heat sink to contact a wider air environment in the heat dissipation cavity 11, improving the heat dissipation efficiency.

[0034] In some embodiments of this application, a signal lamp lens 312 is provided between the signal lamp 311 and the first light-inlet surface 21. The signal lamp lens 312 can optimize the angle of the light emitted by the signal lamp 311 and can directionally calibrate the divergent light emitted by the signal lamp 311, so that the light is incident on the first light-inlet surface 21 of the optical lens 2 at a more concentrated and precise angle. Combined with the possible tilt setting of the first light-inlet surface 21 and its direct orientation with the signal lamp 311, the light optimized by the signal lamp lens 312 can further improve the optical compatibility with the first light-inlet surface 21, reduce the scattering loss of light during the incident process, greatly improve the optical coupling efficiency, ensure that more light can enter the optical lens 2 efficiently and be transmitted along a preset path, enhance the output brightness and directionality of the signal lamp 311, and ensure the warning and indication effect of the vehicle signal lamp 311.

[0035] According to some embodiments of the present application, the lighting assembly 100 for a vehicle includes a signal light panel 32 further comprising a third panel segment 323 disposed at the rear end of the second panel segment 322 and attached to the lighting assembly 4.

[0036] The second plate segment 322 extends towards the rear and slopes downward away from the light outlet channel 12. The third plate segment 323 extends further on this basis and fits into the lighting assembly 4, making full use of the idle space behind the lighting assembly 4 in the heat dissipation cavity 11. This makes the overall structure of the signal light plate 32 fit tightly with the lighting assembly 4, avoiding the waste of space caused by the reserved redundant gap between the two. It does not require expanding the longitudinal depth or lateral width of the heat dissipation cavity 11 to accommodate the extended part of the signal light plate 32, thus maintaining the compact size of the heat dissipation cavity 11 to the maximum extent, which meets the needs of the thin and narrow shape evolution of vehicle lights.

[0037] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a first heat sink 33 configured as a plurality of first fins 331, each first fin 331 extending obliquely in a direction perpendicular to the second plate segment 322.

[0038] Compared to a single integral heat dissipation structure, the multiple first fins 331 significantly increase the heat dissipation contact area, providing more conduction and dissipation paths for the heat generated by the signal light board 32 during operation. This fundamentally improves heat dissipation capacity, enabling rapid dissipation of heat accumulated in the signal light board 32 and preventing high temperatures from affecting the performance or lifespan of the signal light 311. The arrangement of each first fin 331 extending perpendicularly to the second plate segment 322 ensures tight contact between the first fin 331 and the second plate segment 322, shortening the path of heat conduction from the signal light board 32 through the second plate segment 322 to the first fin 331. This reduces heat loss during heat conduction, improves heat conduction efficiency, and allows the heat generated by the signal light 311 to be quickly transferred to the surface of the first fin 331 for dissipation.

[0039] The inclined extension characteristic of the first fin 331 is adapted to the structural feature of the second plate segment 322 extending rearward and tilting downward away from the light emission channel 12. The first fin 331 naturally tilts along the shape of the second plate segment 322, without occupying the optical space around the light emission channel 12, and without structural interference with other components such as the third plate segment 323 of the lighting assembly 4 in the heat dissipation cavity 11. There is no need to increase the lateral width, longitudinal height, or longitudinal depth of the heat dissipation cavity 11 to avoid the first fin 331, thus maintaining the compact layout of the heat dissipation cavity 11 to the maximum extent. At the same time, an orderly gap structure is formed between the multiple inclined first fins 331. These gaps can guide the airflow in the heat dissipation cavity 11, enhance the thermal convection effect, and allow the heat on the surface of the first fin 331 to be quickly carried away by the flowing air, further improving the heat dissipation efficiency and forming a synergistic effect of conductive and convective heat dissipation.

[0040] According to some embodiments of this application, a lighting assembly 100 for a vehicle includes a lighting assembly 4 comprising: a lighting plate 42 and a second heat sink 43. The lighting plate 42 is disposed in a heat sink cavity 11 and is arranged parallel to a second light-incoming surface 22. A lighting lamp 411 is disposed on the lighting plate 42 and is directly opposite to the second light-incoming surface 22. The second heat sink 43 is disposed on the side of the lighting plate 42 away from the second light-emitting end 41.

[0041] The lighting plate 42 is disposed in the heat dissipation cavity 11 and parallel to the second light-inlet surface 22. The lighting lamp 411 is fixed to the lighting plate 42 and faces the second light-inlet surface 22. The parallel arrangement creates a uniform light propagation gap between the lighting plate 42 and the second light-inlet surface 22, ensuring that the light emitted by the lighting lamp 411 can be incident on the second light-inlet surface 22 at a vertical or near-vertical angle, reducing refraction loss and direction deviation when the light is incident. The facing arrangement aligns the optical receiving areas of the light source and the optical lens 2, avoiding light waste caused by incident position deviation, significantly improving optical coupling efficiency, and ensuring that the brightness, uniformity, and directionality of the light emitted by the lighting lamp 411 meet the preset requirements of vehicle lighting.

[0042] The second heat sink 43 is disposed on the side of the lighting panel 42 away from the second light-emitting end 41. Being away from the second light-emitting end 41 avoids the heat sink from blocking the light propagation path, ensuring that the light emitted by the lighting lamp 411 can be directed to the second light-incoming surface 22 without obstruction. At the same time, this side directly corresponds to the core heat-generating area of ​​the lighting lamp 411. The second heat sink 43 can be closely attached to the heat source, shortening the path of heat conduction from the lighting panel 42 to the heat sink, reducing energy loss during heat conduction, and quickly dissipating the heat generated by the lighting lamp 411 during operation, avoiding the accumulation of high temperature from affecting the performance or service life of the lighting lamp 411.

[0043] In some embodiments of this application, the second heat sink 43 is disposed on the side of the lighting panel 42 away from the second light-emitting end 41 and the side facing the second light-emitting end 41. The side of the second heat sink 43 facing the second light-emitting end 41 avoids the second light-emitting end 41, which can increase the heat dissipation area of ​​the second heat sink 43.

[0044] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a heat-conducting plate 421 disposed between a lighting panel 42 and a second heat sink 43.

[0045] Understandably, since the power of the lighting lamp 411 is greater than that of the signal lamp 311, it generates more heat and requires the heat-conducting plate 421 to assist in heat conduction. The heat-conducting plate 421 is located between the lighting lamp plate 42 and the second heat sink 43, which can fill the tiny gap between the two surfaces and increase the heat conduction contact area. At the same time, the heat-conducting plate 421 itself has efficient heat conduction characteristics. Compared with the direct contact method, it further shortens the path of heat conduction from the lighting lamp plate 42 to the second heat sink 43, reduces energy loss during heat conduction, and allows the large amount of heat generated by the lighting lamp 411 to be transferred to the second heat sink 43 more quickly and evenly. This prevents heat from accumulating on the lighting lamp plate 42 and causing local high temperature, ensuring the long-term stable operation of the lighting lamp 411 and extending its service life.

[0046] In some embodiments of this application, the second heat sink 43 is configured as a plurality of second fins 431, each second fin 431 extending obliquely in a direction perpendicular to the lighting panel 42.

[0047] The lighting assembly 100 for a vehicle according to some embodiments of this application further includes: a cooling fan 6, which is disposed on one side of the lamp housing 1 in the width direction and communicates with the heat dissipation cavity.

[0048] It should be noted that an airflow channel 7 is formed between the multiple first fins 331 and the multiple second fins 431. The inlet of the airflow channel 7 is connected to the air outlet of the cooling fan 6, and the extension direction of the airflow channel 7 is consistent with the air outlet direction of the cooling fan 6. In addition, a ventilation groove 5 connected to the heat dissipation cavity 11 is provided on the other side of the lamp housing 1 in the width direction, or on the top or bottom of the lamp housing 1.

[0049] A cooling fan 6 is positioned on one side of the lamp housing 1 along its width and communicates with the heat dissipation cavity 11. An airflow channel 7 is formed between multiple first fins 331 and multiple second fins 431. The inlet of the airflow channel 7 is connected to the outlet of the cooling fan 6, and its extension direction is consistent with the outlet direction. This allows the airflow generated by the cooling fan 6 to enter the fin gaps without obstruction along a preset path, reducing resistance loss during airflow transmission and ensuring precise airflow through the core heat dissipation areas of the first heat sink 33 and the second heat sink 43. For the lighting assembly 4, which generates more heat, the heat-conducting plate 421 has efficiently transferred the heat to the second fins 431. The directional airflow can quickly remove a large amount of heat from the surface of the second fins 431, while also taking into account the heat dissipation of the first fins 331 of the signal light assembly 3. This achieves differentiated heat dissipation adaptation between the two types of components, preventing the lighting lamp 411 from being affected by high temperature accumulation and ensuring the stable operation of the signal light 311.

[0050] The ventilation slot 5, located on the other side of the width direction of the lamp housing 1 or at the top and bottom, is connected to the heat dissipation cavity 11. The airflow blown out by the cooling fan 6 carries heat after passing through the fins and is smoothly discharged from the heat dissipation cavity 11 through the ventilation slot 5. At the same time, a negative pressure is formed to guide the continuous replenishment of external cold air, so that a continuous and stable convection circulation is formed in the heat dissipation cavity 11. The cooling fan 6 and the ventilation slot 5 are both located in the edge area of ​​the lamp housing 1, utilizing the idle space of the lamp housing 1. This does not occupy the light output channel 12 or the core area for component installation, does not change the facing layout of the optical lens 2 and the two types of components, and does not increase the overall volume and thickness of the lamp.

[0051] In some embodiments of this application, the cross-sections of the first fin 331 and the second fin 431 can be quincunx-shaped, wavy, or straight.

[0052] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a heat dissipation cavity 11 having a vent slit 5 open at the top and / or bottom; it also includes a cooling fan 6 disposed at the rear of the lamp housing 1 and used to exhaust air toward the heat dissipation cavity 11.

[0053] In other embodiments of this application, the cooling fan 6 is located at the rear of the lamp housing 1 and exhausts air towards the heat dissipation cavity 11. Combined with the ventilation slots 5 open at the top and / or bottom of the heat dissipation cavity 11, the overall heat dissipation efficiency of the lamp assembly 100 is significantly improved. The rear of the lamp housing 1 is the receiving area of ​​the heat dissipation cavity 11. The cooling fan 6 exhausts air towards the heat dissipation cavity 11 at this location, allowing the airflow to cover the signal lamp assembly 3 and the lighting assembly 4 inside the heat dissipation cavity 11. Especially for the lighting assembly 4, which generates more heat, the airflow can directly act on the surface of its second heat sink 43. Combined with the optimized design of the heat-conducting plate 421 transferring heat to the second heat sink 43, the heat exchange between heat and airflow is accelerated. At the same time, the airflow can also flow fully through the first heat sink 33 of the signal lamp assembly 3, achieving full coverage of the heat-generating areas of both types of components and avoiding local heat accumulation. The ventilation slots 5 are open at the top and / or bottom of the heat dissipation cavity 11, forming an airflow circulation path with the cooling fan 6 at the rear of the lamp housing 1. After the cooling fan 6 sends cold air into the cavity, the cold air absorbs heat and is converted into hot air after contacting the heat-generating components and heat sink. The hot air rises naturally due to buoyancy or flows along the cavity space to the top / bottom, and is finally quickly discharged from the heat dissipation cavity 11 through the open ventilation slot 5. At the same time, external cold air continues to enter through the fan, improving heat exchange efficiency and ensuring the heat dissipation needs of the signal light component 3.

[0054] The vehicle according to an embodiment of this application is briefly described below.

[0055] The vehicle according to the embodiments of this application includes the lighting assembly 100 of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lighting assembly 100 of any of the above embodiments, the reduction in the volume of the vehicle lighting assembly 100 according to this application reduces the vehicle's installation space requirements, reserving more space for components at the front of the vehicle body, improving the layout flexibility of the vehicle chassis and front body, and conforming to the trend of thinner and narrower headlights, thus optimizing the overall aerodynamic design of the vehicle. The reduction in component weight directly reduces the vehicle's curb weight, reduces energy loss during driving, significantly improves the driving range for electric vehicles, and optimizes fuel economy for fuel vehicles. In addition, the integration of the lighting assembly 100 reduces the number of parts and assembly steps in the vehicle lighting system, shortens the vehicle's final assembly production cycle, and reduces the overall vehicle manufacturing cost. The reliability of the lighting operation, which is ensured by heat dissipation concentrated in the heat dissipation cavity 11, also indirectly reduces the frequency of lighting-related failures during vehicle after-sales maintenance, improving the overall durability of the vehicle.
