Description

Technical Field

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

[0002] As a core component of automotive active safety and interaction, vehicle headlights integrate two core functions: road lighting and light signal indication. They play an indispensable role in ensuring driving safety, enabling signal transmission, and improving vehicle visibility.

[0003] The headlights have both low beam and high beam functions. The low beam primarily meets the lighting needs of the area in front of the vehicle, providing sufficient illumination without dazzling other drivers on the road. The high beam is used when there are no other vehicles on the road or when they are far away, providing a longer lighting range in front of the vehicle.

[0004] In related technologies, the illumination range of headlights mainly covers the front of the vehicle. In some usage scenarios, such as turning or intersections, there are significant blind spots, which affect driving safety. Summary of the Invention

[0005] This application provides a headlight and vehicle, aiming to solve the problem that headlights have blind spots and are difficult to meet diverse scene lighting needs.

[0006] In a first aspect, embodiments of this application propose a headlight. The headlight includes: a lamp housing; a main lighting module disposed within the lamp housing, the main lighting module including a first lighting module and a second lighting module arranged at intervals along the left-right direction of the vehicle, the first lighting module being used to form at least a low beam widening pattern, the second lighting module being used to form an adaptive high beam pattern, and the second lighting module being used to form a low beam cutoff line pattern; an auxiliary lighting module disposed within the lamp housing and located on one side of the main lighting module along the height direction of the vehicle, the auxiliary lighting module being used to form an extended lighting area with a preset horizontal divergence angle; wherein, the low beam widening pattern and the low beam cutoff line pattern together form a low beam pattern, and the extended lighting area is located on the side of the low beam widening pattern away from the vehicle's centerline and overlaps with the low beam widening pattern.

[0007] The headlight of this embodiment includes a main lighting module and an auxiliary lighting module within its housing. The first and second lighting modules of the main lighting module together form a low beam pattern, while the second lighting module can independently form an adaptive high beam pattern. Furthermore, the auxiliary lighting module can form an extended lighting area overlapping with the widened low beam pattern, effectively expanding the low beam's illumination width. This configuration integrates low beam and adaptive high beam functions, achieving a wider lateral coverage range while maintaining a clear cutoff line for the low beam pattern. Thus, the low beam provides effective illumination whether driving straight or turning, effectively mitigating blind spots on the sides in scenarios such as curves and intersections, thereby improving driving safety and reliability at night and in complex road conditions.

[0008] In some embodiments, the low beam cutoff line has a cutoff line inflection point, which is movable along the left-right direction of the vehicle.

[0009] This design, firstly, makes the low beam illumination area more closely match the road surface when cornering, thus improving the safety and reliability of cornering. Secondly, compared to related technologies that use rotating the main lighting module to move the cutoff line inflection point, this design avoids mechanical wear issues and improves response speed.

[0010] In some embodiments, the auxiliary lighting module includes at least one first auxiliary lighting module and at least one second auxiliary lighting module. The first auxiliary lighting module is located below the first lighting module and is fixed in position in the left-right direction of the vehicle. The second auxiliary lighting module is located below the second lighting module and is capable of swinging between an initial position and a maximum position in the left-right direction of the vehicle.

[0011] When the second auxiliary lighting module is in the initial position, the first auxiliary lighting module and the second auxiliary lighting module form an extended lighting area with a first horizontal divergence angle; When the second auxiliary lighting module is in the maximum position, the first auxiliary lighting module and the second auxiliary lighting module form an extended lighting area with a second horizontal divergence angle, which is greater than the first horizontal divergence angle.

The first auxiliary lighting module and the second auxiliary lighting module form an extended lighting area with a second horizontal divergence angle, and / or the cutoff line inflection point can move towards the inside of the curve along the left and right direction of the vehicle.

[0014] This design offers several advantages. First, it enables adaptive low-beam lighting, enhancing the intelligence and automation of the headlights, increasing the vehicle's functionality and added value, and improving the user experience.

[0015] In some embodiments, the first lighting module is also used to form a high beam pattern; The headlight also includes at least one high beam enhancement auxiliary module disposed within the lamp housing. The high beam enhancement auxiliary module is located on the side of the main lighting module opposite to the auxiliary lighting module, and the high beam enhancement auxiliary module is used to form an auxiliary high beam pattern.

[0016] This configuration can further enhance the functionality, intelligence, and scene adaptability of the headlights, improve the vehicle's functionality and added value, enhance the user experience, and also help to further improve driving safety and reliability.

[0017] In some embodiments, the auxiliary lighting module includes at least one first auxiliary lighting module and at least one second auxiliary lighting module, wherein the first auxiliary lighting module is located below the first lighting module and the second auxiliary lighting module is located below the second lighting module; The headlight also includes an ambient light module disposed within the lamp housing, wherein each of the first auxiliary lighting module, the second auxiliary lighting module, and the high beam enhancement auxiliary module is integrated with a corresponding ambient light module within the same housing.

[0018] This design integrates ambient lighting with auxiliary lighting functions. On one hand, it gives the headlights ambient lighting capabilities, thereby enhancing their versatility and adaptability to different scenarios, increasing the vehicle's functionality and added value, and ultimately improving the user experience. On the other hand, it helps reduce the weight and cost of the headlights, improving the overall space utilization within the headlight assembly.

[0019] In some embodiments, the first auxiliary lighting module, the second auxiliary lighting module, and the high beam enhancement auxiliary module are all capable of moving between a retracted position and a light-emitting position along the longitudinal direction of the vehicle. The first auxiliary lighting module, the second auxiliary lighting module, and the high beam enhancement auxiliary module move to the light-emitting position in response to a welcome trigger signal from the vehicle, and move to the retracted position in response to a locking signal from the vehicle.

[0020] This design offers several advantages. First, it extends the lifespan and reliability of the headlights. Second, it enhances the vehicle's technological sophistication and sense of occasion, increasing its added value. Third, it improves the vehicle's aesthetics and overall appearance. Furthermore, it provides the hardware foundation for various vehicle modes, further enhancing the headlights' versatility and adaptability to different scenarios.

[0021] In some embodiments, the first auxiliary lighting module, the second auxiliary lighting module, and the high beam enhancement auxiliary module can all swing along the height direction of the vehicle. In response to the vehicle's welcome trigger signal, the headlights enter the welcome mode. In the welcome mode, the first auxiliary lighting module, the second auxiliary lighting module, and the high beam enhancement auxiliary module swing along the height direction of the vehicle, and the ambient light module emits light according to a preset lighting mode.

[0022] This design offers several advantages. First, it enhances the functionality and adaptability of the headlights to different scenarios. It also provides the hardware foundation for expanding interactive functions, allowing for the development of more scenario-based lighting interaction modes and improving the headlights' scalability. Second, it enhances the vehicle's technological feel, human-vehicle interaction experience, and sense of luxury. Furthermore, it prevents the core lighting source from suffering wear and tear in unnecessary scenarios, saving energy, reducing costs, and extending its lifespan.

[0023] In some embodiments, the auxiliary lighting module includes at least one first auxiliary lighting module and at least one second auxiliary lighting module, wherein the first auxiliary lighting module is located below the first lighting module and the second auxiliary lighting module is located below the second lighting module; The high beam enhancement auxiliary module, the first auxiliary lighting module, and the second auxiliary lighting module can all swing along the height direction of the vehicle; The headlights also include at least one of the following: high-speed off-road mode, low-speed off-road mode, off-road safety mode, night camping mode, and steep hill start mode; In the high-speed off-road mode, the first lighting module forms a widened low beam and a high beam, and the high beam enhancement auxiliary module forms an auxiliary high beam. In the low-speed off-road mode, the first lighting module forms a widened low beam pattern, the second lighting module forms a low beam cutoff line pattern, and the first auxiliary lighting module and the second auxiliary lighting module form an extended lighting area with the second horizontal divergence angle. In the off-road safety mode, the high beam enhancement auxiliary module, the first auxiliary lighting module, and the second auxiliary lighting module rotate a first preset angle along the side away from the main lighting module, and the high beam enhancement auxiliary module, the first auxiliary lighting module, and the second auxiliary lighting module are in a flashing state.

In the steep slope start-up mode, the first lighting module forms a low beam widening beam pattern and a high beam beam pattern, and the high beam enhancement auxiliary module rotates a second preset angle along the side away from the main lighting module to form an auxiliary high beam beam pattern.

[0024] This configuration can further enhance the functionality, intelligence, and scene adaptability of the headlights, improve the vehicle's functionality and added value, enhance the user experience, and also help to further improve driving safety and reliability.

[0025] In some embodiments, the high beam enhancement auxiliary module, the first auxiliary lighting module, and the second auxiliary lighting module each include a first color temperature light source and a second color temperature light source, wherein the first color temperature light source is a white light source, and the color temperature of the second color temperature light source is lower than that of the first color temperature light source, wherein: In the night camping mode, the color temperature of the extended lighting area formed by the first auxiliary lighting module and the second auxiliary lighting module is adjustable.

[0026] This setup allows campers to choose the lighting atmosphere according to their camping needs, thereby increasing the diversity of nighttime camping modes and enhancing the atmosphere and user experience.

[0027] In some embodiments, the headlight further includes an off-road mode for severe weather. In the off-road mode for severe weather, the first lighting module forms a low beam widening beam and a high beam beam, the second color temperature light source of the first auxiliary lighting module and the second auxiliary lighting module is lit to form an extended lighting area, and the second color temperature light source of the high beam enhancement auxiliary module is lit to form an auxiliary high beam beam.

[0028] After being superimposed, the entire lighting beam is rendered as yellow-white light, enabling long-distance penetrating illumination in adverse weather conditions, thereby improving driving safety and reliability in such conditions.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of this application provides a headlight 10. The headlight 10 includes a lamp housing 100, a main lighting module 200, and an auxiliary lighting module 300. The main lighting module 200 is disposed within the lamp housing 100 and includes a first lighting module 210 and a second lighting module 220 arranged at intervals along the left-right direction of the vehicle. (Refer to...) Figure 3 and Figure 4 The first lighting module 210 is used to form at least a low beam broadening pattern P1, and the second lighting module 220 is used to form an adaptive high beam pattern B. The second lighting module 220 is also used to form a low beam cutoff line pattern P2. The auxiliary lighting module 300 is disposed within the lamp housing 100 and located on one side of the main lighting module 200 along the height direction of the vehicle, as shown in the reference. Figure 1 and Figure 5 The auxiliary lighting module 300 is used to form an extended lighting area K with a preset horizontal divergence angle. The low beam widening pattern P1 and the low beam cutoff line pattern P2 together form the low beam pattern P. The extended lighting area K is located on the side of the low beam widening pattern P1 away from the vehicle's centerline L and overlaps with it. The left-right direction of the vehicle is defined as the Y-direction, the height direction as the Z-direction, and the front-rear direction as the X-direction.

[0037] The headlights 10 are lighting assemblies installed on both sides of the front of the vehicle. The headlights 10 can be divided into left headlights and right headlights, which are arranged symmetrically.

[0038] The lamp housing 100 is the outer housing structure of the headlight 10, with an internal cavity for housing and protecting each lighting module. The front end of the lamp housing is usually equipped with a transparent cover to allow light from each lighting module to escape.

[0039] The main lighting module 200 is a collection of modules that undertake the core lighting function of the road and is the main lighting unit of the headlight 10. The auxiliary lighting module 300 is a collection of modules that undertakes the supplementary lighting function and is used to extend the areas that the low beam cannot cover.

[0040] The main lighting module 200 includes a first lighting module 210 and a second lighting module 220. The first lighting module 210 is used to form at least a near-beam broadening beam pattern P1, such as... Figure 1 , Figure 3 and Figure 5 As shown, the low beam widening pattern P1 is a portion of the low beam pattern P responsible for its lateral width, with its upper boundary being a horizontal light-dark line. With the vehicle's centerline L as a reference, the low beam widening pattern P1 can illuminate an area with a horizontal divergence angle of approximately ±40°. When the first lighting module 210 is only used to form the low beam widening pattern P1, it can be considered a low beam module; when the first lighting module 210 can also form the high beam pattern S, it can be considered a high-low beam module. It is understood that the first lighting module 210 possesses a complete light source, heat sink, optical elements, and housing.

[0041] The second lighting module 220 is used to form an adaptive high beam pattern B; that is, the second lighting module 220 is an ADB (Adaptive Driving Beam) module. For example... Figure 4 As shown, the adaptive high beam pattern B is composed of multiple independently controllable sub-spots b1. By selectively illuminating or extinguishing the light source corresponding to each sub-spot b1, the brightness of each sub-spot b1 can be varied. Thus, when an oncoming vehicle is present in a certain area in front of the vehicle, the spot illuminating the location of the oncoming vehicle can be extinguished, creating a localized dark area and preventing glare for the driver of the oncoming vehicle. Simultaneously, the sub-spots in other areas remain illuminated, thereby achieving adaptive high beam illumination. It is understood that the second lighting module 220 also has multiple independent light sources, heat sinks, optical elements, and housings. These multiple light sources can be, for example, an LED array composed of multiple independent LED (Light Emitting Diode) chips, or an LED / mini LED chip integrating multiple pixel units. Each LED (or each pixel unit) can be independently controlled to form a sub-spot b1 in the adaptive high beam pattern B.

[0042] like Figure 3 and Figure 5 As shown, the second lighting module 220 can also form a low beam cutoff line shape P2, which refers to a portion of the low beam shape P responsible for achieving the low beam cutoff line. The upper boundary of the low beam cutoff line shape P2 is a zigzag line with a lower left side and a higher right side. The lower left boundary prevents the light from directly shining into the eyes of drivers in oncoming lanes; the higher right boundary extends the illumination distance on the right side, thereby increasing the illumination range and distance. It can be understood that by splicing the low beam cutoff line shape P2 and the low beam widening shape P1 in the vertical direction (Z direction), a complete low beam shape P can be achieved.

[0043] Since the second illumination module 220 is an ADB module, the brightness of each sub-spot b1 can be independently controlled. Therefore, when the light sources corresponding to each sub-spot b1 that needs to form the near-beam cutoff line shape P2 are lit, and other light sources are turned off, the second illumination module 220 can present the near-beam cutoff line shape P2.

[0044] The auxiliary lighting module 300 is located on one side of the main lighting module 200 along the height direction of the vehicle. For example, the auxiliary lighting module 300 can be positioned above or below the main lighting module 200. Preferably, the auxiliary lighting module 300 is located below the main lighting module 200. This positional relationship prevents the light from the auxiliary lighting module 300 from scattering upwards and interfering with the low beam pattern P (especially above the cutoff line) formed by the main lighting module 200.

[0045] The auxiliary lighting module 300 is used to form an extended lighting area K with a preset horizontal divergence angle. The extended lighting area K is located on the side of the low beam widening pattern P1 away from the vehicle's centerline L and overlaps with the low beam widening pattern P1. That is, the auxiliary lighting module 300 can achieve the width expansion of the low beam pattern P in the left and right directions. The preset horizontal divergence angle refers to the horizontal illumination range of the extended lighting area K formed by the auxiliary lighting module 300 itself. The preset horizontal divergence angle can be, for example, 30°, 45°, 60°, etc., and can be flexibly set according to the actual situation.

[0046] It should be noted that all headlights 10 in the attached diagram are left headlights. When the headlight 10 is a left headlight, the extended illumination area K of the left headlight 10 is located to the left of the low beam widening pattern P1, which can extend the left-side illumination width of the low beam; when the headlight 10 is a right headlight, the extended illumination area K of the right headlight is located to the right of the low beam widening pattern P1, which can extend the right-side illumination width of the low beam. (Refer to...) Figure 1 When the low beam of the headlight and the extended lighting zones K on both sides are lit simultaneously, the horizontal lighting range of the low beam in the left and right directions can be extended.

[0047] It is understandable that the extended lighting area K formed by the auxiliary lighting module 300 can be superimposed on the near beam broadening pattern P1 at a preset angle. For example, as... Figure 1As shown, when the extended lighting area K is superimposed on the vehicle's centerline L at an angle of 0°, taking a horizontal half-divergence angle of 40° and a preset horizontal divergence angle of 60° for the low beam widening beam pattern P1, the total horizontal illumination angle of the superimposed low beam is ±60°, effectively increasing the low beam illumination width. Alternatively, when the extended lighting area K is superimposed on the vehicle's centerline L at an angle greater than 0°, such as 20°, the total horizontal illumination angle of the superimposed low beam is ±80°, further increasing the low beam illumination width. Therefore, the preset horizontal divergence angle of the auxiliary lighting module 300 and its superposition position with the low beam widening beam pattern P1 can be flexibly configured according to actual needs, thereby effectively widening the side illumination range of the low beam.

[0048] The headlight 10 of this embodiment includes a main lighting module 200 and an auxiliary lighting module 300 within the lamp housing 100. The first lighting module 210 and the second lighting module 220 of the main lighting module 200 can jointly form a low beam pattern P, while the second lighting module 220 can also independently form an adaptive high beam pattern B. Furthermore, the auxiliary lighting module 300 can form an extended lighting area K overlapping with the widened low beam pattern P1, effectively expanding the illumination width of the low beam. This configuration integrates the low beam function with the adaptive high beam function, and while ensuring a clear cutoff line for the low beam pattern P, it also achieves a wider lateral coverage range for the low beam. Thus, whether driving straight or turning, the low beam can provide effective illumination, thereby improving the problem of blind spots in side views at curves and intersections, and ultimately enhancing driving safety and reliability at night and in complex road conditions.

[0049] Secondly, the headlight 10 integrates three main functions within the same lamp housing 100: basic low beam illumination, adaptive high beam illumination, and low beam lateral extension illumination. Furthermore, the second lighting module 220 simultaneously constitutes the low beam pattern P and the adaptive high beam pattern B. This allows for module reuse and functional integration within the lamp housing space, enabling the headlight 10 to carry more functions within a limited space. On one hand, this improves the integration and structural compactness of the headlight 10, meeting the requirements for miniaturization and lightweighting, thereby enhancing the adaptability and flexibility of the headlight 10 to the overall vehicle styling. On the other hand, the headlight 10 can flexibly switch lighting modes according to different driving scenarios, achieving adaptive lighting, which also helps to improve the functional versatility of the headlight 10.

[0050] Furthermore, the low beam pattern P is formed jointly by the first illumination module 210 and the second illumination module 220. The first illumination module 210 is responsible for forming the low beam broadening pattern P1, and the second illumination module 220 is responsible for forming the low beam cutoff line pattern P2, which is lower on the left and higher on the right. The extended illumination area K is only superimposed on the low beam broadening pattern P1. This not only helps to improve the quality and illumination effect of the low beam pattern P, but also helps to ensure the anti-glare effect of the low beam.

[0051] In addition, each of the auxiliary modules in the first lighting module 210, the second lighting module 220, and the auxiliary lighting module 300 has an independent light source, heat sink, optical element, housing, and other components. That is, all of the above are independent vehicle lamp modules installed in preset positions within the lamp housing 100, and each can emit light independently. This is equivalent to the headlight 10 achieving a modular design, which also helps to improve the convenience of maintenance and replacement of the headlight 10 and reduce maintenance costs.

[0052] Reference Figure 3 and Figure 5 In some embodiments, the low beam cutoff line shape P2 has a cutoff line inflection point Q, which can move along the left and right directions of the vehicle. It should be noted that the cutoff line inflection point Q is the endpoint of the low beam cutoff line on the left side closest to the high beam side on the right.

[0053] As mentioned above, the second illumination module 220 is an ADB module, and the brightness of each sub-spot b1 can be independently controlled. Therefore, if the light sources corresponding to each sub-spot b1 that form the near beam cutoff line shape P2 remain lit, the near beam cutoff line shape P2 will not change, and the cutoff line inflection point Q will also remain unchanged. If the lighting state of each light source is changed, the near beam cutoff line shape P2 will change accordingly, and the cutoff line inflection point Q will also change. For example, by gradually extinguishing the sub-spots b1 to the right of the cutoff line inflection point Q, the cutoff line inflection point Q can be gradually moved to the right; similarly, by gradually illuminating the sub-spots b1 to the left of the cutoff line inflection point Q, the cutoff line inflection point Q can be gradually moved to the left.

[0054] By setting the cutoff inflection point Q of the low beam cutoff line P2 to be movable left and right, the dynamic cutoff line function of the low beam P can be realized, allowing the headlight 10 to adjust the position of the cutoff inflection point Q in real time according to the vehicle's driving status (such as turning, curves, etc.). With this setting, firstly, when the vehicle enters a curve, by moving the cutoff inflection point Q towards the inside of the curve, the brightness and darkness of the low beam P's cutoff line dynamically adjust with the curve's direction, making the low beam's illumination area more closely match the road surface, thus improving the safety and reliability of driving on curves. Secondly, the movement of the cutoff inflection point Q can work in conjunction with the extended illumination area K of the auxiliary lighting module 300 to further eliminate blind spots on curves, further improving driving safety and reliability. Furthermore, compared to related technologies that use rotating the main lighting module to move the cutoff inflection point Q, this embodiment can adjust the position of the cutoff inflection point Q in real time according to steering wheel angle signals, vehicle speed signals, etc., eliminating mechanical wear issues and improving response speed.

[0055] Understandably, the movement of the cutoff line inflection point Q is a local adjustment to the low beam cutoff line shape P2. When a vehicle passes through a curve, although the lighting direction changes, the anti-glare function of the cutoff line is always maintained, preventing glare interference to vehicles in the oncoming lane. Optionally, to further improve safety, in some cases, if an oncoming vehicle is detected, the cutoff line inflection point Q can be restored to its initial regulatory position.

[0056] like Figure 2 and Figure 6 As shown, in some embodiments, the auxiliary lighting module 300 includes at least one first auxiliary lighting module 310 and at least one second auxiliary lighting module 320. The first auxiliary lighting module 310 is located below the first lighting module 210 and maintains a fixed position in the left-right direction of the vehicle. The second auxiliary lighting module 320 is located below the second lighting module 220 and can be positioned in an initial position along the left-right direction of the vehicle. Figure 2 ) and maximum position ( Figure 6 The second auxiliary lighting module 320 swings between the two positions. When the second auxiliary lighting module 320 is in its initial position, the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K1 with a first horizontal divergence angle α. When the second auxiliary lighting module 320 is in its maximum position, the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K2 with a second horizontal divergence angle β, where the second horizontal divergence angle β is greater than the first horizontal divergence angle α.

[0057] This embodiment proposes a specific structure for an auxiliary lighting module 300. The auxiliary lighting module 300 includes a first auxiliary lighting module 310 and a second auxiliary lighting module 320, wherein the second auxiliary lighting module 320 is a dynamic auxiliary lighting module, and the first auxiliary lighting module 310 is a static auxiliary lighting module. The number of each module can be one, two, or more; the number of each module can be the same or different, and this application does not impose any limitations on this. The second auxiliary lighting module 320 rotates left and right about the Z-axis. Specifically, the second auxiliary lighting module 320 is connected to a first driving member, which directly drives the second auxiliary lighting module 320 to rotate left and right.

[0058] When the second auxiliary lighting module 320 is in its initial position, the emitted light from the second auxiliary lighting module 320 and the emitted light from the first auxiliary lighting module 310 together form an extended lighting area K1 with a first horizontal divergence angle α. For example, in one embodiment, the emitted light from the second auxiliary lighting module 320 and the emitted light from the first auxiliary lighting module 310 can overlap. In this embodiment, if there is only one first auxiliary lighting module 310 and one second auxiliary lighting module 320, the horizontal divergence angle of the emitted light from both is the first horizontal divergence angle α. If there are multiple first auxiliary lighting modules 310 or multiple second auxiliary lighting modules 320, the multiple first auxiliary lighting modules 310 together form emitted light with the first horizontal divergence angle α (the emitted light from two adjacent first auxiliary lighting modules 310 can be horizontally overlapped and spliced), and the multiple second auxiliary lighting modules 320 together form emitted light with the first horizontal divergence angle α (the emitted light from two adjacent second auxiliary lighting modules 320 horizontally overlapped and spliced). For example, another approach is to have the emitted light from the second auxiliary lighting module 320 and the emitted light from the first auxiliary lighting module 310 have a certain horizontal overlap angle, such as 20°, 30°, or 40°. In this approach, if there is only one first auxiliary lighting module 310 and one second auxiliary lighting module 320, the horizontal divergence angle of their emitted light is less than the first horizontal divergence angle α. If there are multiple first auxiliary lighting modules 310 or multiple second auxiliary lighting modules 320, the multiple first auxiliary lighting modules 310 together form emitted light with an angle less than the first horizontal divergence angle α, and the multiple second auxiliary lighting modules 320 together form emitted light with an angle less than the first horizontal divergence angle α. The first horizontal divergence angle α of the extended illumination area K formed by the two is equal to the sum of the horizontal divergence angle of the total emitted light from the first auxiliary lighting module 310 and the horizontal divergence angle of the total emitted light from the second auxiliary lighting module 320, minus the horizontal overlap angle.

[0059] When the second auxiliary lighting module 320 rotates to its maximum position, the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K2 with a second horizontal divergence angle β, which is greater than the first horizontal divergence angle α. That is, as the second auxiliary lighting module 320 rotates, its emitted light can move away from the vehicle's central axis L, thereby increasing the horizontal divergence angle of the extended lighting area K.

[0060] It is understandable that when there is only one second auxiliary lighting module 320, rotating the second auxiliary lighting module 320 alone can extend the extended lighting area K from the first horizontal divergence angle α to the second horizontal divergence angle β. When there are multiple second auxiliary lighting modules 320, the multiple second auxiliary lighting modules 320 preferably rotate synchronously. This ensures that the light pattern splicing relationship between the multiple second auxiliary lighting modules 320 is not disrupted, and also allows the extended lighting area K to extend from the first horizontal divergence angle α to the second horizontal divergence angle β. In this case, if each second auxiliary lighting module 320 is provided with a corresponding first driving member, the first driving members rotate synchronously; or, a first driving member is used, and its output terminal is connected to multiple second auxiliary lighting modules 320 simultaneously to achieve synchronous rotation.

[0061] In this embodiment, the auxiliary lighting module 300 includes a first auxiliary lighting module 310 and a second auxiliary lighting module 320. The first auxiliary lighting module 310 is a static auxiliary lighting module, and the second auxiliary lighting module 320 is a dynamic auxiliary lighting module. By adjusting the rotation position of the second auxiliary lighting module 320 in the left and right directions, the horizontal divergence angle of the extended lighting area K can be varied between a first horizontal divergence angle α and a second horizontal divergence angle β. With this setting, firstly, in scenarios such as urban roads and ordinary curves, the second auxiliary lighting module 320 can remain in its initial position, thereby forming an extended lighting area K1 with a first horizontal divergence angle α, meeting daily lateral lighting needs while avoiding over-illumination; in scenarios requiring extremely wide lateral visibility, such as sharp turns and low-speed off-road driving, the second auxiliary lighting module 320 swings to its maximum position, thereby forming a wider extended lighting area K2 with a second horizontal divergence angle β, effectively covering the lateral blind spots that need to be observed. This enables on-demand lighting, allowing for adaptive adjustment of the horizontal lighting range based on actual driving scenarios, achieving a balance between functionality and energy consumption, and improving driving safety and reliability. Secondly, since only the second auxiliary lighting module 320 requires a drive mechanism, it simplifies control logic and reduces costs and failure rates. Furthermore, even if the second auxiliary lighting module 320 fails, the first auxiliary lighting module 310 can still provide basic lateral lighting, thus creating design redundancy and further improving the reliability and stability of the auxiliary lighting module 300. In addition, the oscillation of the second auxiliary module 320 can be continuously adjusted, thus the horizontal divergence angle of the extended lighting zone K is continuously variable. For example, the horizontal divergence angle of the extended lighting zone K can be adjusted in real time based on steering wheel angle, vehicle speed, and curve curvature. This further enhances the intelligence and scene adaptability of the headlights 10, increases the vehicle's functional diversity and added value, and improves the user experience.

[0062] Optionally, in a specific embodiment, taking the left headlight 10 in the accompanying drawings as an example, there are two first auxiliary lighting modules 310 and two second auxiliary lighting modules 320. The horizontal divergence angle of the emitted light from both the first auxiliary lighting modules 310 and the two second auxiliary lighting modules 320 is 60°, and they overlap with the low beam broadening pattern P1 starting from 0°. The left and right rotation angle of the two second auxiliary lighting modules 320 is 30°. The first lighting module 210 is located to the left of the second lighting module 220, and the two second auxiliary lighting modules 320 are located below the second lighting module 220. The two first auxiliary lighting modules 310 are located below the first lighting module 210. It can be understood that the right headlight is symmetrically arranged.

[0063] At this time, if the auxiliary lighting modules 300 in the left and right headlights are not illuminated, the low beam pattern P is typically a horizontal illumination range of ±40°. When the two second auxiliary lighting modules 320 are in their initial positions, the auxiliary lighting modules 300 are illuminated, and the extended illumination area K overlaps, expanding to a horizontal illumination range of ±60°. When the two second auxiliary lighting modules 320 are in their maximum positions, the auxiliary lighting modules 300 are illuminated, and the extended illumination area K overlaps, expanding to a horizontal illumination range of ±90°, achieving full illumination from 90° to 90° on the left and right sides of the vehicle. At this time, when the vehicle passes through intersections, forks, enters and exits garages, or performs low-speed off-road maneuvers, the driver can perceive the road conditions to the side using peripheral vision without turning their head, thus further improving driving safety and reliability.

[0064] Of course, it is understood that the specific parameters mentioned above are merely illustrative examples and are not intended to limit this application. By reasonably setting parameters such as the left and right rotation angles of the second auxiliary lighting module 320, the horizontal divergence angles of the first auxiliary lighting module 310 and the second auxiliary lighting module 320, and the light pattern overlap angle between them, the horizontal illumination range after the near beam and the extended illumination area K are superimposed can be further increased. The specific settings can be flexibly adjusted according to actual conditions and needs.

[0065] In some embodiments, the headlight 10 includes a basic low beam lighting mode, and the headlight 10 also includes at least one of an urban road low beam mode and a cornering lighting mode.

[0066] like Figure 3 As shown, in the basic low beam illumination mode, the first illumination module 210 is configured to form a low beam broadening beam pattern P1, and the second illumination module 220 is configured to form a low beam cutoff line beam pattern P2.

[0067] like Figure 7 As shown, in the low beam mode of urban roads, the first lighting module 210 is configured to form a low beam broadening beam shape P1, the second lighting module 220 is configured to form a low beam cutoff line beam shape P2, and the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K1 with a first horizontal divergence angle α.

[0068] like Figure 5 As shown, in the cornering lighting mode, the first lighting module 210 is configured to form a low beam widening beam shape P1, and the second lighting module 220 is configured to form a low beam cutoff beam shape P2. The first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K2 with a second horizontal divergence angle β, and / or the cutoff line inflection point Q can move towards the inside of the curve along the left and right directions of the vehicle.

[0069] This embodiment proposes multiple low beam lighting modes for the headlight 10. Among them, the basic low beam lighting mode, the urban road low beam mode, and the cornering lighting mode can be distinguished according to the relevant provisions in the national standard GB / T 30036-2013. The basic low beam lighting mode corresponds to level C and is the default low beam mode. The urban road low beam mode corresponds to level V. The cornering lighting mode can be activated based on any of the above low beam levels and dynamically adjusts the light pattern according to the steering angle, navigation information, image information, etc., to enhance the illumination on the inside of the curve.

[0070] When the headlight 10 is in basic low beam mode, energy consumption is lowest, making it suitable for well-lit road sections. When the headlight 10 is in urban road low beam mode, the extended lighting area K has a first horizontal divergence angle α, which can appropriately supplement the horizontal illumination range of the low beam. When the headlight 10 is in curve lighting mode, the extended lighting area K switches to a second horizontal divergence angle β, and / or the inflection point Q of the low beam cutoff line moves towards the inside of the curve to enhance the illumination on the inside of the curve. The curve lighting mode can be automatically activated in real time based on vehicle steering wheel angle signals, vehicle speed signals, navigation information, image information, etc.

[0071] This design, firstly, allows the headlights 10 to actively adjust their lighting behavior according to the driving environment by defining different low-beam lighting modes, achieving adaptive low-beam lighting. This enhances the intelligence and automation of the headlights 10, increases the vehicle's functional versatility and added value, and improves the user experience. Secondly, it enables precise light coverage according to different environments and scenarios, avoiding light pollution and eliminating blind spots, achieving a balance between supplemental lighting and light pollution control. This also helps save energy and improves driving safety and reliability. Furthermore, the low-beam beam pattern P and the extended lighting area K can dynamically adjust according to curves, further enhancing the vehicle's technological and premium feel.

[0072] Optionally, in one specific embodiment, when the vehicle is in motion, the vehicle's cameras, radar, etc., identify that the vehicle is traveling in a city or on a paved road at night, and the vehicle speed sensor detects that the vehicle speed is less than a certain threshold, such as 70 km / h, and the steering wheel angle sensor detects that the steering wheel angle change is greater than a certain threshold, such as 10°, then the vehicle controller (ECU, Electronic Control Unit) sends a CAN signal to the headlight controller to enable the cornering lighting mode.

[0073] Typically, both the first lighting module 210 and the second lighting module 220 have a dimming mechanism that can slightly adjust the illumination range of the main lighting (swinging up and down and left and right). Therefore, in some embodiments, the headlight 10 also includes a highway driving mode, in which the first lighting module 210 and the second lighting module 220 can be rotated upwards in the basic low beam lighting mode to adjust the light beam and make the light shine further.

[0074] like Figure 2 and Figure 6 , Figure 9 As shown and referenced Figure 8 In some embodiments, the first lighting module 210 is also used to form a high beam pattern S. The headlight 10 also includes at least one high beam enhancement auxiliary module 400 disposed within the lamp housing 100. The high beam enhancement auxiliary module 400 is located on the side of the main lighting module 200 opposite to the auxiliary lighting module 300, and is used to form an auxiliary high beam pattern S1. For example, the high beam enhancement auxiliary module 400 may be disposed above the main lighting module 200.

[0075] In this embodiment, the first lighting module 210, in addition to providing the low beam broadening pattern P1, is further configured to form the high beam pattern S; that is, the first lighting module 210 can be a high and low beam lighting module. Simultaneously, the headlight 10 also includes at least one high beam enhancement auxiliary module 400 for forming an auxiliary high beam pattern S1. For example... Figure 8 and Figure 9 As shown, the auxiliary high beam pattern S1 of the high beam enhancement auxiliary module 400 can be a converging spotlight that is directly superimposed on the central area of ​​the high beam pattern S, thereby improving the brightness and illumination distance of the central area. Of course, in other embodiments, the auxiliary high beam pattern S1 can also be an emitted light with a certain horizontal width, which can extend the horizontal illumination range of the high beam, and so on.

[0076] Based on the above structure, the headlight 10 also includes at least a basic high beam lighting mode, an enhanced high beam lighting mode, and an adaptive high beam lighting mode.

[0077] In the basic high beam lighting mode, the first lighting module 210 is configured to form a low beam broadening pattern P1 and a high beam pattern S, thereby achieving basic high beam lighting.

[0078] like Figure 9 As shown, in the enhanced high beam lighting mode, the first lighting module 210 is configured to form a low beam broadening beam shape P1 and a high beam beam shape S, and the high beam enhancement auxiliary module 400 is configured to form an auxiliary high beam beam shape S1, thereby increasing the center brightness and / or horizontal illumination range of the high beam beam shape S, and achieving stronger high beam lighting.

[0079] In the adaptive high beam mode (ADB mode), the first lighting module 210 is configured to form a low beam broadening pattern P1, and the second lighting module 220 is configured to form an adaptive high beam pattern B, thereby achieving adaptive high beam illumination.

[0080] It is understandable that the various modes of high beam can be switched by a mechanical switch, or by a soft switch on the vehicle's infotainment system or smart device, or by automatic switching based on the vehicle's driving environment (such as vehicle speed, oncoming vehicles, image information, etc.), or by voice switching, etc. This application does not impose any restrictions on these.

[0081] This configuration can further enhance the functionality, intelligence, and scene adaptability of the headlights 10, improve the vehicle's functionality and added value, enhance the user experience, and also help to further improve driving safety and reliability.

[0082] Optionally, in a specific embodiment, the number of high beam enhancement auxiliary modules 400 is four, two of which are located above the first lighting module 210 and two of which are located above the second lighting module 220.

[0083] like Figure 2 and Figure 6 As shown, in some embodiments, the headlight 10 further includes an ambient light module 500 disposed within the lamp housing 100, and each of the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 is integrated with a corresponding ambient light module 500 within the same housing.

[0084] The ambient lighting module 500 can generate ambient light. Each of the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 is integrated with a corresponding ambient lighting module 500 within the same housing. In other words, each auxiliary module and an ambient lighting module 500 are physically integrated into a single assembly unit. Taking the second auxiliary lighting module 320 as an example, the second auxiliary lighting module 320 and an ambient lighting module 500 are integrated within the same housing, forming an integrated assembly unit, which is then installed in a predetermined position within the headlight housing 100. When the second auxiliary lighting module 320 rotates left or right, the ambient lighting module 500 also rotates synchronously. Furthermore, although physically integrated, the optical systems of the second auxiliary lighting module 320 and the ambient lighting module 500 are independent and can be independently controlled for light output. That is, the second auxiliary lighting module 320 can emit a light beam to form the extended lighting area K, and the ambient light module 500 can emit an ambient light beam. They can emit simultaneously or separately. Optionally, when integrated, the light sources of the two can be independent, the optical components can be independent, and in addition to sharing a housing, they can also share a heat sink, etc. The specific configuration can be flexibly set according to the actual situation.

[0085] This configuration allows for the integration of ambient lighting and auxiliary lighting functions. On one hand, it endows the headlights 10 with ambient lighting capabilities, thereby enhancing their functional versatility and adaptability to various scenarios, increasing the vehicle's functionality and added value, and ultimately improving the user experience. On the other hand, it helps reduce the weight and cost of the headlights 10, and improves the overall space utilization within the lamp.

[0086] In some embodiments, the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 can all move between a retracted position and a light-emitting position along the front-rear direction of the vehicle. The first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 move to the light-emitting position in response to the vehicle's welcome trigger signal, and move to the retracted position in response to the vehicle's locking signal.

[0087] The "retracted position" refers to the position where the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 are retracted to a certain depth within the lamp housing 100 in the front-back direction. The "light-emitting position" refers to the position where the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 extend in the front-back direction to their initial working position for achieving optimal light pattern coordination. In the light-emitting position, the extended lighting area K formed by the first auxiliary lighting module 310 and the second auxiliary lighting module 320 can overlap and splice with the low beam broadening light pattern P1, and the auxiliary high beam light pattern S1 of the high beam enhancement auxiliary module 400 can be superimposed and / or spliced ​​with the high beam light pattern S.

[0088] A vehicle's welcome trigger signal can be, for example, a vehicle unlock signal or a proximity sensing signal. In some scenarios, a welcome trigger signal is generated when a user presses the unlock button with the remote key, or when a vehicle equipped with a keyless entry system detects the key entering a designated range via its sensing module. Alternatively, in other scenarios, the vehicle establishes a connection with a smart device such as a mobile phone or watch, and when the device's signal strength steadily increases with approach, it is determined to be a welcome trigger signal indicating that the user has actively approached. Of course, the welcome trigger signal can also take other forms, and this application does not limit this.

[0089] Each of the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 can be equipped with a separate second drive unit. This second drive unit can be, for example, an electric actuator that can move the corresponding first auxiliary lighting module 310, second auxiliary lighting module 320, and high beam enhancement auxiliary module 400 in the forward and backward direction. It is understood that, due to their integration, each ambient light module 500 can move synchronously.

[0090] When the vehicle is parked, the first auxiliary lighting module 310, the second auxiliary lighting module 320, the high beam enhancement auxiliary module 400, and the ambient lighting module 500 can retract to a storage position, achieving a semi-hidden function. They only return to their illuminated position upon receiving a welcome trigger signal. This design firstly protects the first auxiliary lighting module 310, the second auxiliary lighting module 320, the high beam enhancement auxiliary module 400, and the ambient lighting module 500, improving the lifespan and reliability of the headlights 10. Secondly, it enhances the vehicle's technological and ceremonial appeal, increasing its added value. Furthermore, when in the retracted position, the human eye can only perceive the main lighting module 200, thus improving the vehicle's aesthetics and cleanliness. In addition, it provides the hardware foundation for various vehicle modes, further enhancing the functional versatility and scene adaptability of the headlights 10.

[0091] like Figure 2 , Figure 6 and Figure 10 As shown, in some embodiments, the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 can all swing along the height direction of the vehicle (rotate around the Y-axis). In response to the vehicle's welcome trigger signal, the headlight 10 enters the welcome mode. In the welcome mode, the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 swing along the height direction of the vehicle, and the ambient light module 500 emits light according to a preset lighting mode.

[0092] Each of the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 can be equipped with a separate third drive unit. This third drive unit could be, for example, a rotation drive unit, capable of driving the corresponding first auxiliary lighting module 310, second auxiliary lighting module 320, and high beam enhancement auxiliary module 400 to rotate in the vehicle's height direction. It is understood that, since each ambient light module 500 is integrated with its corresponding auxiliary function module in the same housing, each ambient light module 500 can move synchronously.

[0093] This embodiment describes the operation of the headlight 10 in welcome mode. When the vehicle receives a welcome trigger signal, the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 oscillate along the height of the vehicle. For example, they can oscillate back and forth or oscillate according to a periodic pattern. At this time, the ambient light module 500 also oscillates synchronously. Furthermore, the ambient light module 500 emits light according to a preset lighting mode, while the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 remain off. At this time, the multiple ambient light modules 500 can form welcome lighting.

[0094] This configuration, firstly, enables the headlight 10 to perform a welcome function, thereby enhancing its functional versatility and adaptability to various scenarios. Furthermore, it provides the hardware foundation for expanding interactive functions, allowing the headlight 10 to develop more scenario-based lighting interaction modes, thus improving its scalability. Secondly, it creates a welcoming visual effect with a sense of ceremony and technology, enhancing the vehicle's technological feel, human-vehicle interaction experience, and sense of luxury. In addition, it allows for the separation and coordination of functional lighting and ambient lighting, with synchronized movement during operation, eliminating the need for a separate motion mechanism for the ambient lighting module 500, and ensuring that only the ambient lighting module 500 emits light during operation. This avoids unnecessary wear and tear on the core functional lighting source in unnecessarily, saving energy, reducing costs, and extending its service life.

[0095] Optionally, the preset lighting mode can be, for example, multiple ambient light modules 500 lighting up and turning off in a directional manner and / or periodically changing in brightness, the light source of each ambient light module 500 flashing, the light color of different ambient light modules 500 changing in a preset sequence, and the brightness / color of all lights changing rhythmically, etc., which can be flexibly set according to the actual situation.

[0096] It is understandable that if the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 also have the freedom of movement in the forward and backward directions (moving between the storage position and the light-emitting position), then under the trigger of the welcome trigger signal, the above modules can first move to the light-emitting position and then execute the welcome mode.

[0097] In some embodiments, the headlight 10 further includes at least one of a high-speed off-road mode, a low-speed off-road mode, an off-road safety mode, a night camping mode, and a steep hill start mode.

[0098] Specifically, such as Figure 9 As shown, in high-speed off-road mode, the first lighting module 210 forms a low beam widening beam pattern P1 and a high beam beam pattern S, the high beam enhancement auxiliary module 400 forms an auxiliary high beam beam pattern S1, and the second lighting module 220 and the auxiliary lighting module 300 can remain in an off state.

[0099] In this way, by superimposing the high beam pattern S and the auxiliary high beam pattern S1, the brightness of both near and far-field lighting can be significantly improved, meeting the high requirements for long-distance visibility during high-speed off-road driving, thereby improving driving safety and reliability in high-speed off-road mode.

[0100] like Figure 5As shown, in low-speed off-road mode, the first lighting module 210 forms a low beam widening beam shape P1, the second lighting module 220 forms a low beam cutoff beam shape P2, the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K2 with a second horizontal divergence angle β, and the high beam enhancement auxiliary module 400 can remain in an off state.

[0101] Thus, while maintaining basic low-beam illumination, the headlight 10 significantly widens the illumination range on both sides of the vehicle by extending the illumination area K, making it easier for the driver to observe nearby obstacles, curbs, and terrain changes, thereby improving safety during low-speed off-road driving. Optionally, in this mode, the cutoff point Q of the low-beam cutoff line P2 can also be configured to move in the left-right direction.

[0102] It should be noted that the enhanced high beam mode and the high-speed off-road mode use the same module activation method; the difference lies in the applicable scenarios. When the vehicle is detected driving in urban areas or on paved roads based on image information, vehicle sensor information, navigation information, radar information, etc., the enhanced high beam mode can be selected based on the surrounding environment (e.g., no oncoming vehicles). When the vehicle is detected driving off-road on unpaved roads, the low-speed off-road mode or high-speed off-road mode can be selected based on vehicle speed: when the vehicle speed is below a certain threshold, it switches to low-speed off-road mode; when the vehicle speed is above a certain threshold, it switches to high-speed off-road mode. Of course, these modes can also be entered manually via hard switches in the cabin, soft switches on in-vehicle infotainment systems, or voice communication; this application does not impose any restrictions on this.

[0103] In off-road safety mode, the high beam enhancement auxiliary module 400, the first auxiliary lighting module 310, and the second auxiliary lighting module 320 rotate a first preset angle along the side away from the main lighting module 200, and the high beam enhancement auxiliary module 400, the first auxiliary lighting module 310, and the second auxiliary lighting module 320 are in a flashing state.

[0104] Off-road safety mode refers to an active safety warning mode in which the headlights 10 activate when the vehicle becomes stuck, breaks down, needs to stop for rescue, or encounters other emergencies requiring external warning on off-road terrain. In this mode, refer to... Figure 10The high beam enhancement auxiliary module 400, the first auxiliary lighting module 310, and the second auxiliary lighting module 320 rotate a first preset angle, such as 20°, along the side opposite to the main lighting module 200. The high beam enhancement auxiliary module 400 rotates upward to direct the beam upward, while the first auxiliary lighting module 310 and the second auxiliary lighting module 320 rotate downward to direct the beam downward. Then, the high beam enhancement auxiliary module 400, the first auxiliary lighting module 310, and the second auxiliary lighting module 320 simultaneously flash on. For example, the flashing frequency can be 0.8~1Hz, with three short flashes, three long flashes, and three short flashes. The "short" flashes last approximately 0.5 seconds, and the "long" flashes last approximately 1.5 seconds, cycling in sequence to form an SOS alarm light signal, making it easy for people, rescue vehicles, helicopters, etc., to spot.

[0105] This configuration allows the headlight 10 to also have an alarm function, which helps to further improve driving safety and reliability.

[0106] In night camping mode, the first lighting module 210 forms a near-beam broadened light pattern P1, and the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K with a third horizontal divergence angle, the third horizontal divergence angle being greater than or equal to the first horizontal divergence angle α and less than or equal to the second horizontal divergence angle β.

[0107] In some situations, outdoor camping scenarios may also occur. At night, the vehicle's headlights 10 can be switched to night camping mode. In this mode, the first lighting module 210 forms a widened low-beam beam P1, and the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K to illuminate the campsite area to the side of the vehicle, providing illumination for the site. Furthermore, the second lighting module 220 is turned off to avoid producing a glaring cutoff line beam.

[0108] This setup provides lighting for camping scenarios, thereby enhancing the functionality and scene adaptability of the headlight 10 and improving the user experience.

[0109] Optionally, when the vehicle's sensors (such as gear position sensor, vehicle speed sensor, etc.) detect that the vehicle is in a parked state, and the vehicle's light sensor detects that the current environment is dim, the sensors send signals to the vehicle controller (ECU, Electronic Control Unit). After receiving these signals, the ECU can trigger the night camping mode; otherwise, the night camping mode cannot be triggered. Alternatively, the night camping mode can be activated by clicking the soft switch on the in-vehicle infotainment system, in-vehicle equipment, mobile phone, or other smart devices, or by voice activation. The ECU then sends a CAN message to the headlight controller 10 via the vehicle's CAN signal to activate the night camping mode.

[0110] like Figure 8 As shown, in the steep slope start mode, the first lighting module 210 forms a low beam widening beam shape P1 and a high beam beam shape S. The high beam enhancement auxiliary module 400 rotates a second preset angle along the side away from the main lighting module 200, for example, rotating upward by 20°, and the high beam enhancement auxiliary module 400 forms an auxiliary high beam beam shape S1.

[0111] When a vehicle is parked on a steep slope and is about to start, or when the vehicle is about to drive on a steep slope, the headlights 10 can be in steep slope start mode. At this time, while the low beams can illuminate the nearby road surface normally, the high beams cannot illuminate the top of the slope in advance due to their angle. Therefore, in steep slope start mode, while the first lighting module 210 switches to high beam illumination, the high beam enhancement auxiliary module 400 rotates upward to form an auxiliary high beam pattern S1. The auxiliary high beam pattern S1 and the high beam pattern S may separate. This expands the vertical illumination range, and the high beam enhancement auxiliary module 400 can illuminate the top of the slope in advance, reducing blind spots. This also helps improve the safety and reliability of starting the vehicle on a steep slope.

[0112] Optionally, the vehicle's cameras, radar, and other sensors monitor the surrounding environment and road conditions in real time, while the vehicle attitude sensor monitors the vehicle's attitude. When the cameras, radar, and other sensors detect that there is an uphill section ahead of the vehicle, or when the vehicle attitude sensor detects that the vehicle is deviating, a signal is output to the vehicle's ECU. After receiving these signals, the ECU sends them to the light controller to trigger the hill start mode.

[0113] In some embodiments, the high beam enhancement auxiliary module 400, the first auxiliary lighting module 310, and the second auxiliary lighting module 320 all include a first color temperature light source and a second color temperature light source. The first color temperature light source is a white light source with a color temperature of around 4000K. The color temperature of the second color temperature light source is lower than that of the first color temperature light source. For example, the second color temperature light source can be a warm white light source with a color temperature of around 3000K.

[0114] In night camping mode, the color temperature of the extended lighting area K formed by the first auxiliary lighting module 310 and the second auxiliary lighting module 320 is adjustable.

[0115] For example, the color temperature can be adjusted by adjusting the lighting ratio and brightness of the first color temperature light source and the second color temperature light source in the first auxiliary lighting module 310 and the second auxiliary lighting module 320.

[0116] This setup allows campers to choose the lighting atmosphere according to their camping needs, thereby increasing the diversity of nighttime camping modes and enhancing the atmosphere and user experience.

[0117] like Figure 11As shown, in some embodiments, the headlight 10 also includes an off-road mode for severe weather. In the off-road mode for severe weather, the first lighting module 210 forms a low beam pattern P1 and a high beam pattern S, the second color temperature light sources of the first auxiliary lighting module 310 and the second auxiliary lighting module 320 are illuminated to form an extended lighting area K, and the second color temperature light source of the high beam enhancement auxiliary module 400 is illuminated to form an auxiliary high beam pattern S1.

[0118] Because the secondary color temperature light source is yellowish-white light with a color temperature of around 3000K, it has strong penetrating power in low-visibility environments such as rain, fog, and snow, effectively preventing glare. Therefore, in the off-road mode for severe weather, the first lighting module 210 provides basic high beam illumination. Then, the secondary color temperature light sources in the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 are illuminated. After superposition, the entire illumination beam is rendered as yellowish-white light, achieving long-distance penetrating illumination in severe weather, thereby improving driving safety and reliability in adverse weather conditions.

[0119] In some embodiments, the headlight 10 also has a rally racing mode. In the rally racing mode, the first lighting module 210 forms a low beam broadening pattern P1 and a high beam pattern S, the high beam enhancement auxiliary module 400 forms an auxiliary high beam pattern S1, the second lighting module 220 forms an adaptive high beam pattern B, the first auxiliary lighting module 310 and the second auxiliary lighting module 320 form an extended lighting area K2 with a second horizontal divergence angle β, and the second color temperature light source in the first auxiliary lighting module 310, the second auxiliary lighting module 320, and the high beam enhancement auxiliary module 400 is lit, and the lighting effect is as follows: Figure 12 As shown. This allows for the maximization of the lighting effect.

[0120] In some embodiments, such as Figure 2 As shown, the headlight 10 also includes a first signal light module 600, which is located on the side of the high beam enhancement auxiliary module 400 opposite to the main lighting module 200. The first signal light module 600 is elongated and may include at least one of daytime running lights, position lights, and turn signals. This facilitates further improvement in the functional versatility of the headlight 10.

[0121] In some embodiments, such as Figure 2 As shown, the main lighting module 200 also integrates a second signal light module 700 within the housing. The light-emitting surface of the second signal light module 700 is arranged around the light-emitting surface of either the first lighting module 210 or the second lighting module 220. The second signal light module 700 is annular and may include one of the following: daytime running lights, position lights, or turn signals. This facilitates further improvement in the functional versatility and integration of the headlight 10.

[0122] Secondly, embodiments of this application provide a vehicle including the headlight 10 described in the first aspect.

[0123] This design helps to improve the problem of blind spots on the sides in scenarios such as curves and intersections, thereby improving driving safety and reliability at night and in complex road conditions.

[0124] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
