Description

Technical Field

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

[0002] The vehicle lighting module is the core component of a vehicle lighting system used to achieve optical functions. It generally includes a light-emitting element and a reflector. The reflector is used to focus the light emitted by the light-emitting element and project it onto the target area in front of the vehicle. In related technologies, the light-emitting element requires high power to ensure that the illuminance value of the target area meets the requirements, resulting in high energy consumption for the vehicle lighting module. Utility Model Content

[0003] This application provides a vehicle lighting module, a vehicle lighting device, and a vehicle that can reduce energy consumption.

[0004] In a first aspect, this application provides a vehicle lighting module, which includes a first light-emitting element and a first reflector. The first reflector is disposed opposite to the light-emitting surface of the first light-emitting element along a first direction. The first reflector is configured to reflect light emitted from the light-emitting surface into light along a second direction, forming a near-beam pattern. The first reflector includes a three-zone structure, which is configured to reflect light emitted from the light-emitting surface into a three-zone pattern. Along a third direction, the three-zone structure is located on one side of the light-emitting surface, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0005] The vehicle lighting module provided in this application has a three-zone structure located on one side of the emitting surface along a third direction. The first and second directions are perpendicular to each other along the third direction, causing the three-zone structure to be offset from the emitting surface. In the first reflector, the illuminance value of the part directly facing the emitting surface is larger, while the illuminance value of the part offset from the emitting surface is relatively smaller. The offset arrangement of the three-zone structure from the emitting surface results in a relatively smaller overall illuminance value for the three-zone structure. The three-zone structure is used to reflect light into a three-zone light pattern, which is a component of the low beam light pattern and is located above the cutoff line. Its main function is to illuminate traffic signs such as road signs with a lower, compliant illuminance value, while avoiding glare for drivers of oncoming vehicles. The relatively small illuminance value of the three-zone structure and the relatively small illuminance value of the three-zone light pattern ensure that the three-zone light pattern is well-matched to regulatory requirements. By placing the three-zone structure on one side of the emitting surface along a third direction, the three-zone light pattern still meets regulatory requirements. Furthermore, by placing the three-zone structure on one side of the emitting surface along the third direction, a larger portion of the reflector used to form the main low-beam pattern can be positioned directly opposite the emitting surface. This results in a higher illuminance value for the portion forming the main low-beam pattern, leading to a relatively high illuminance value for the main low-beam pattern itself. Thus, even with a relatively low power for the first emitting element, the illuminance value of the main low-beam pattern remains relatively high. Therefore, this application provides a vehicle lighting module that, even with a relatively low power for the first emitting element, still provides a relatively high illuminance value for the main low-beam pattern, and the illuminance values ​​of the three-zone pattern are well-matched with regulatory requirements. In other words, even with a relatively low power for the first emitting element, the illuminance value of the low-beam pattern meets the requirements, which reduces energy consumption.

[0006] In some alternative implementations of this application, along a third direction, the light-emitting surface is located in the middle of the first reflector, and the three-zone structure is located at one end of the first reflector.

[0007] By positioning the emitting surface in the middle of the first reflector along the third direction, all parts of the first reflector can receive relatively uniform illumination from the emitting surface, ensuring full utilization of each part. By positioning the three-zone structure at one end of the first reflector along the third direction, the distance between the three-zone structure and the emitting surface is greater, placing the three-zone structure in the area of ​​lower illuminance on the first reflector. This results in a better match between the three-zone light pattern and regulations, allowing more of the portion of the first reflector used to form the primary low-beam light pattern to be placed in the area of ​​higher illuminance, thus improving the performance of the vehicle lighting module.

[0008] In some optional implementations of this application, the vehicle lighting module further includes a light-blocking member, which forms a receiving cavity with a light-emitting port oriented in the same direction as the second direction. The light-blocking member also has a light-entry hole, the depth direction of which is parallel to the first direction, and the light-entry hole connects the inside and outside of the receiving cavity. A first reflector is disposed within the receiving cavity, facing the light-emitting port. A light-emitting surface is disposed within the light-entry hole, along a third direction, with at least a portion of the three-zone structure located on one side of the light-entry hole.

[0009] By placing the first reflector inside the receiving cavity of the light-blocking member, with the first reflector facing the light outlet of the receiving cavity and the light outlet facing the same direction as the second direction, the light reflected by the first reflector is emitted out of the receiving cavity through the light outlet and then into the external environment. The light-blocking member can block the light reflected by the first reflector that deviates from the light outlet, thereby eliminating excess stray light and enabling the low beam pattern to better meet regulatory requirements.

[0010] By forming a light-entry hole in the light-blocking component, with the depth direction of the light-entry hole parallel to the first direction, and the light-emitting surface disposed within the light-entry hole, the light emitted from the light-emitting surface can pass through the light-entry hole and reach the first reflector. On the one hand, this allows part of the structure of the first light-emitting component to be disposed outside the receiving cavity, enabling the light-blocking component to be relatively small, thus saving material consumption. On the other hand, the sidewall of the light-entry hole can block the light emitted by the first light-emitting component to a certain extent, constraining the light and ensuring that as much of the light passing through the light-entry hole as possible is reflected by the first reflector before exiting from the light-emitting port. This helps reduce the amount of light that exits directly from the light-emitting port without being reflected by the first reflector, and helps the near-beam shape better meet regulatory requirements. Moreover, the fact that part of the structure of the first light-emitting component can be disposed outside the receiving cavity also makes it less likely for the first light-emitting component and the first reflector to interfere with each other, facilitating the arrangement of the first reflector within the receiving cavity.

[0011] By positioning at least a portion of the three-zone structure along a third direction on one side of the light entrance aperture, the overall illuminance value of the three-zone structure is relatively small, thus ensuring that the three-zone light pattern better matches regulatory requirements. In the first reflector, the illuminance value is higher in the portion directly opposite the light entrance aperture and relatively lower in the portion offset from the light entrance aperture. The fact that at least a portion of the three-zone structure is located on one side of the light entrance aperture further reduces the overall illuminance value of the three-zone structure. Moreover, the fact that at least a portion of the three-zone structure is located on one side of the light entrance aperture allows for a greater proportion of the portion in the first reflector used to form the primary low-beam light pattern to be positioned directly opposite the light entrance aperture, resulting in a larger illuminance value for this portion and consequently a relatively larger illuminance value for the primary low-beam light pattern. Therefore, even with a relatively low power output from the first light-emitting element, the illuminance value of the primary low-beam light pattern remains relatively high, leading to superior performance of the vehicle lighting module.

[0012] In some alternative implementations of this application, along the first direction, the three-zone structure is located at the end of the first reflector closer to the light-emitting surface.

[0013] In this way, the distance between the entrance aperture and the three-zone structure along the axial direction is relatively close. It can be understood that, with at least a portion of the three-zone structure located on one side of the entrance aperture along a third direction, the closer the three-zone structure is to the entrance aperture, the greater the degree of obstruction by the light-blocking component, and the less likely light passing through the entrance aperture will reach the three-zone structure. By positioning the three-zone structure along the first direction at the end of the first reflector closer to the light-emitting surface, the illuminance value of the three-zone structure is reduced, thereby making the light pattern of the three zones more compatible with regulatory requirements.

[0014] Furthermore, the three-zone structure is located in the area of ​​the first reflector where the light-blocking component is relatively large. This allows the portion of the first reflector used to form the main low beam pattern to be placed in the area where the light-blocking component is relatively small. This results in a larger illuminance value for the portion used to form the main low beam pattern, which in turn results in a relatively large illuminance value for the main low beam pattern. Thus, even if the power of the first light-emitting component is relatively small, the illuminance value of the main low beam pattern is still relatively large, resulting in superior performance of the vehicle headlight lighting module.

[0015] In some alternative implementations of this application, a light-blocking portion is formed on the surface of the cavity on one side where the light-entry hole is formed, and the light-blocking portion extends circumferentially along the light-entry hole.

[0016] In this way, the light-blocking part can block the light emitted by the first light-emitting element to a certain extent, thereby constraining the light and making the light passing through the light entrance hole reflect as much as possible through the first reflector before being emitted from the light exit hole. This reduces the amount of light emitted directly from the light exit hole without being reflected by the first reflector, which helps to make the low beam shape better meet regulatory requirements.

[0017] In some alternative implementations of this application, the inner wall of the light-blocking part is combined with the side wall of the light-entry hole.

[0018] In this way, the light-blocking part can block the light emitted by the first light-emitting element to a large extent, thereby constraining the light and ensuring that as much of the light passing through the light entrance hole as possible is reflected by the first reflecting mirror before exiting from the light exit hole. Moreover, the inner wall of the light-blocking part is combined with the side wall of the light entrance hole, which can reduce the bending of the inner surface of the receiving cavity, thereby helping to reduce stress concentration.

[0019] In some alternative implementations of this application, the light-emitting surface faces upward.

[0020] In this way, with the luminous surface facing upwards, the first reflector faces downwards, making it less likely for sunlight to directly hit the first reflector, thus reducing damage to it. Furthermore, since the headlight assembly is positioned relatively low to the human eye, when viewed from above, the first reflector often has many bends and is not perfectly flat. By facing downwards, the first reflector is less easily observed, resulting in a flatter surface for the more visible parts of the headlight assembly.

[0021] In some alternative implementations of this application, the vehicle headlight module further includes a light-blocking member, which forms a receiving cavity with a light-emitting port facing the same direction as the second direction. A first reflector is disposed within the receiving cavity, facing the light-emitting port. The inner surface of the receiving cavity includes a decorative portion, at least a portion of which is formed on the bottom surface of the receiving cavity and located between the light-emitting port and the first reflector.

[0022] Understandably, the light outlet faces the front of the vehicle. The first reflector is positioned opposite both the light outlet and the upward-facing light-emitting surface, meaning it is tilted relatively vertically. Furthermore, the lower end of the first reflector is closer to the rear of the vehicle than its upper end. Along the length of the vehicle, the distance between the lower end of the first reflector and the light outlet is greater than the distance between the upper end and the light outlet. At least a portion of the decorative element is formed on the bottom surface of the receiving cavity, located between the light outlet and the first reflector. The larger distance between the lower end of the first reflector and the light outlet allows for a longer portion of the decorative element formed on the bottom surface of the receiving cavity, making the decorative element more prominent and easily observed. Since the headlight assembly is positioned relatively low to the human eye, and people observe the headlight assembly from top to bottom, the fact that at least a portion of the decorative element is formed on the bottom surface of the receiving cavity further enhances its prominence and makes it easily visible.

[0023] In some optional implementations of this application, the vehicle headlight lighting module further includes a second light-emitting element and a second reflector. The light-emitting surface of the second light-emitting element faces upward, and the second reflector is disposed opposite to the light-emitting surface. The second reflector is configured to reflect the light emitted from the light-emitting surface into light along a second direction to form a high beam pattern.

[0024] In this way, with the light-emitting surface facing upwards, the second reflector faces downwards, making it less likely for sunlight to directly hit the second reflector and reducing the risk of damage. Furthermore, since second reflectors often have numerous bends and are not perfectly flat, their downward orientation makes them less visible to personnel, resulting in a smoother surface for the more easily observable parts of the vehicle's lighting system.

[0037] This application provides a vehicle, such as a sedan, SUV, or sport utility vehicle (SUV).

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 The vehicle provided in this application embodiment includes a vehicle lighting device, which includes a lamp housing 6, a lamp cover, and a vehicle lighting module. The lamp housing 6 has an opening facing the front of the vehicle. The lamp cover is made of a transparent material and is combined with the opening. The vehicle lighting module is disposed inside the lamp housing 6 and located behind the lamp cover. The vehicle lighting module and the lamp cover are disposed opposite to each other. The light emitted by the vehicle lighting module passes through the lamp cover and is emitted into the external environment.

[0039] Please refer to Figure 1, Figure 2 and Figure 3 The vehicle headlight illumination module provided in this application embodiment includes a first light-emitting element 1 and a first reflector 2. The first reflector 2 is disposed opposite to the light-emitting surface of the first light-emitting element 1 along a first direction, and the first reflector 2 is configured to reflect the light emitted from the light-emitting surface into light rays along a second direction, forming a low-beam pattern. Please refer to... Figure 2 , Figure 3 and Figure 4 The first reflector 2 includes a three-zone structure 221, which is configured to reflect the light emitted from the light-emitting surface into a three-zone light pattern. Along the third direction, the three-zone structure 221 is located on one side of the light-emitting surface, and the first direction, the second direction and the third direction are perpendicular to each other.

[0040] The vehicle lighting module provided in this application embodiment has a three-zone structure 221 located on one side of the light-emitting surface along a third direction. The first direction and the second direction are perpendicular to each other along the third direction, so that the three-zone structure 221 is offset from the light-emitting surface. In the first reflector 2, the illuminance value of the part directly facing the light-emitting surface is larger, and the illuminance value of the part offset from the light-emitting surface is relatively smaller. The offset arrangement of the three-zone structure 221 from the light-emitting surface makes the overall illuminance value of the three-zone structure 221 relatively smaller. The three-zone structure 221 is used to reflect light into a three-zone light pattern, which is a component of the low beam light pattern. It is located above the cutoff line between light and dark. Its main function is to illuminate traffic signs such as road signs with a lower, compliant illuminance value, while avoiding glare for drivers of oncoming vehicles. The illuminance value of the three-zone structure 221 is relatively small, and the illuminance value of the three-zone light pattern is relatively small, so that the three-zone light pattern is more compatible with the regulatory requirements. By setting the three-zone structure 221 on one side of the light-emitting surface along a third direction, the three-zone light pattern can still meet the regulatory requirements. Furthermore, by placing the three-zone structure 221 on one side of the emitting surface along the third direction, a larger portion of the reflector used to form the main low-beam pattern can be positioned directly opposite the emitting surface. This results in a larger illuminance value for the portion forming the main low-beam pattern, leading to a relatively large illuminance value for the main low-beam pattern. Thus, even with a relatively low power of the first emitting element 1, the illuminance value of the main low-beam pattern remains relatively high. Therefore, the vehicle lighting module provided in this application provides a relatively large illuminance value for the main low-beam pattern even with a relatively low power of the first emitting element 1, and the illuminance value of the three-zone pattern is well-matched with regulatory requirements. In other words, even with a relatively low power of the first emitting element 1, the illuminance value of the low-beam pattern can meet the requirements, which can reduce energy consumption.

[0041] In the embodiments of this application, please refer to the near-beam beam pattern. Figure 5 .

[0042] Please refer to Figure 2 , Figure 3 and Figure 4It should be explained that in this embodiment of the application, the first reflector 2 is configured to reflect the light emitted by the light-emitting surface into light along the second direction to form a near-beam shape. That is, the vehicle headlight illumination module is a reflector-type module. The light emitted by the light-emitting surface shines on the first reflector 2, and the first reflector 2 directly converges the light into a parallel or regulatory-compliant beam and projects it in front of the vehicle.

[0043] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the three-zone structure 221 can be constructed as a protrusion, the circumferential outline of which can be rectangular, for example, 20 mm in length and 6 mm in width, and the length of which can be in the third direction.

[0044] Please refer to Figure 2 , Figure 3 and Figure 4 It is understood that in the embodiments of this application, when the vehicle headlight module is installed on the vehicle body, the second direction is parallel to the length direction of the vehicle and faces the front of the vehicle. Generally, the first direction is the vertical direction. Of course, in some embodiments of this application, the first direction can also be other directions besides the vertical direction, such as the width direction of the vehicle.

[0045] Please refer to Figure 2 , Figure 3 and Figure 4 Generally, along the length of the vehicle, the luminescent surface is located at the end of the first reflector 2 furthest from the front of the vehicle, and along a third direction, the luminescent surface is located in the middle of the first reflector 2. In some embodiments of this application, along a third direction, the three-zone structure 221 is located at one end of the first reflector 2. By positioning the luminescent surface in the middle of the first reflector 2 along a third direction, each part of the first reflector 2 can receive relatively uniform illumination from the luminescent surface, and each part of the first reflector 2 is fully utilized. By positioning the three-zone structure 221 at one end of the first reflector 2 along a third direction, the distance between the three-zone structure 221 and the luminescent surface is greater, and the three-zone structure 221 is located in the area of ​​lower illuminance value of the first reflector 2. This makes the three-zone light pattern more compatible with regulations, and also allows more of the portion of the first reflector 2 used to form the main low beam pattern to be placed in the area of ​​higher illuminance value, which is beneficial to improving the performance of the vehicle lighting module.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the first light-emitting element 1 can be implemented in various ways, such as a light-emitting diode or a light bulb. The light-emitting diode can be a dual-core light-emitting diode used to emit white light.

[0047] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment of the application, the low beam main beam is located below the light-dark cutoff line, with a high illuminance value, to meet the lighting needs of the main driving roads and make the road surface in front of the vehicle clearly visible.

[0048] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the first reflector 2 may include a flattened reflector and a corner reflector. The flattened reflector is configured to reflect the light emitted by the first light-emitting element 1 into a flattened light pattern, and the corner reflector is configured to reflect the light emitted by the first light-emitting element 1 into a kink light pattern. The flattened light pattern and the kink light pattern are superimposed to form the near-light main light pattern.

[0049] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the widened reflector and the corner reflector are separate structures. The vehicle lighting module also includes a widening dimming mechanism and a corner dimming mechanism. The widening dimming mechanism is driven by the widened reflector and is configured to drive the widened reflector to move relative to the lamp housing 6. The corner dimming mechanism is driven by the widened reflector and is configured to drive the corner reflector to move relative to the lamp housing 6. The widened reflector and the corner reflector can move independently relative to the lamp housing 6, so that the relative positions of the widened light pattern and the corner light pattern are adjustable, which is beneficial to improving the quality of the cutoff line.

[0050] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the distance between the broadened reflective portion and the corner reflective portion is 0.5 to 3 mm, for example, 1 mm or 2 mm. In this way, the distance between the broadened reflective portion and the corner reflective portion is moderate, which can balance the quality of the near-beam main beam and the ease of manufacturing the first reflector 2.

[0051] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, a first blocking portion is provided between the widened reflective portion and the corner reflective portion. This reduces the interference between light from the widened reflective portion and the corner reflective portion. In some embodiments of this application, the first blocking portion has parallel first protrusions extending along a second direction, a textured surface, and an aluminum-plated layer. This allows the first blocking portion to serve both a decorative function and to diffuse light.

[0052] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this application, the broadened reflective portion and the corner reflective portion may be arranged along a third direction. Of course, in some embodiments of this application, the broadened reflective portion and the corner reflective portion may also be arranged along a second direction.

[0053] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the broadened reflective portion includes at least two broadened reflective units 21, and each broadened reflective unit 21 is provided with a first light-emitting element 1. The light emitted by each first light-emitting element 1 is reflected by the corresponding broadened reflective unit 21 and the resulting light patterns are superimposed to form a broadened light pattern.

[0054] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the various broadened reflective portions may be arranged along a third direction. Of course, in some embodiments of this application, the various broadened reflective portions may also be arranged along a second direction.

[0055] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, a second blocking portion is provided between each of the broadened reflective portions. This reduces mutual interference of light at each broadened reflective portion. In some embodiments of this application, the second blocking portion has parallel second protrusions extending along a second direction, a textured surface, and an aluminum-plated layer. This allows the second blocking portion to serve both a decorative function and to diffuse light.

[0056] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the various broadening reflection units 21 are fixedly connected. In this way, the broadening dimming mechanism can drive the various broadening reflection units 21 to move synchronously, which is convenient for adjustment.

[0057] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the corner reflector includes at least two corner reflector units 22, and each corner reflector unit 22 is provided with a first light-emitting element 1. The light emitted by each first light-emitting element 1 is reflected by the corresponding corner reflector unit 22 and the resulting light patterns are superimposed to form a broadened light pattern.

[0058] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this application, the corner reflectors may be arranged along a third direction. Of course, in some embodiments of this application, the corner reflectors may also be arranged along a second direction.

[0059] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, a third blocking portion is provided between each corner reflector. This reduces mutual interference of light at each corner reflector. In some embodiments of this application, the third blocking portion has parallel third protrusions extending along a second direction, a textured surface, and an aluminum-plated layer. This allows the third blocking portion to serve both a decorative function and to diffuse light.

[0060] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the corner reflective units 22 are fixedly connected. In this way, the corner dimming mechanism can drive the corner reflective units 22 to move synchronously, which is convenient for adjustment.

[0061] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the vehicle headlight illumination module further includes a light-blocking member 3. The light-blocking member 3 forms a receiving cavity with a light-emitting port 31. The light-emitting port 31 is oriented in the same direction as the second direction. The light-blocking member 3 forms a light-entry hole 32. The depth direction of the light-entry hole 32 is parallel to the first direction, and the light-entry hole 32 connects the inside and outside of the receiving cavity. A first reflector 2 is disposed in the receiving cavity, facing the light-emitting port 31. A light-emitting surface is disposed in the light-entry hole 32. Along the third direction, at least a portion of the three-zone structure 221 is located on one side of the light-entry hole 32.

[0062] By placing the first reflector 2 inside the receiving cavity of the light-blocking member 3, with the first reflector 2 facing the light outlet 31 of the receiving cavity and the light outlet 31 facing the same direction as the second direction, the light reflected by the first reflector 2 is emitted out of the receiving cavity through the light outlet 31 and then into the external environment. The light-blocking member 3 can block the light reflected by the first reflector 2 that deviates from the light outlet 31, thereby eliminating excess stray light and enabling the near beam pattern to better meet regulatory requirements.

[0063] By forming a light-entry hole 32 in the light-blocking member 3, with the depth direction of the light-entry hole 32 parallel to the first direction and the light-emitting surface disposed within the light-entry hole 32, the light emitted from the light-emitting surface can pass through the light-entry hole 32 and reach the first reflector 2. On the one hand, this allows part of the structure of the first light-emitting member 1 to be disposed outside the receiving cavity, enabling the light-blocking member 3 to be relatively small, which is beneficial for saving material consumption. On the other hand, the sidewall of the light-entry hole 32 can block the light emitted by the first light-emitting member 1 to a certain extent, thereby constraining the light. This ensures that as much of the light passing through the light-entry hole 32 as possible is reflected by the first reflector 2 before exiting from the light-exit port 31, which helps to reduce the amount of light that is directly emitted from the light-exit port 31 without being reflected by the first reflector 2, and helps to better meet regulatory requirements for the near-beam shape. Moreover, the fact that part of the structure of the first light-emitting member 1 can be disposed outside the receiving cavity also makes it less likely for the first light-emitting member 1 and the first reflector 2 to interfere with each other, facilitating the arrangement of the first reflector 2 within the receiving cavity.

[0064] By positioning at least a portion of the three-zone structure 221 along a third direction on one side of the light entrance aperture 32, the overall illuminance value of the three-zone structure 221 is relatively small, thereby ensuring that the three-zone light pattern is more compatible with regulatory requirements. In the first reflector 2, the illuminance value of the portion directly opposite the light entrance aperture 32 is larger, while the illuminance value of the portion offset from the light entrance aperture 32 is relatively smaller. Furthermore, the fact that at least a portion of the three-zone structure 221 is located on one side of the light entrance aperture 32 allows for a greater proportion of the portion in the first reflector 2 used to form the primary low-beam light pattern to be positioned directly opposite the light entrance aperture 32, resulting in a larger illuminance value for this portion and consequently a relatively larger illuminance value for the primary low-beam light pattern. Thus, even with a relatively low power output, the illuminance value of the primary low-beam light pattern remains relatively high, leading to superior performance of the vehicle headlight module.

[0065] Please refer to Figure 2 , Figure 3 and Figure 4 It is understood that in the embodiments of this application, the orientation of the light-emitting surface is from the side of the light-inlet aperture 32 near the outside of the receiving cavity to the side near the inside of the receiving cavity.

[0066] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the first reflector 2 may be a reflective layer covering the inner surface of the receiving cavity. This facilitates the formation of the first reflector 2. The reflective layer may be an aluminum-plated layer, and its reflectivity may be greater than 0.8.

[0067] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this application, the portion of the inner surface of the receiving cavity that avoids the first reflecting mirror 2 includes a diffuse reflection portion. This diffuse reflection portion can diffuse the light from the first light-emitting element 1, thereby eliminating stray light and reducing light loss. In some embodiments of this application, the diffuse reflection portion has parallel fourth convex strips extending along a second direction, a textured surface, and an aluminum plating layer. This allows the diffuse reflection portion to serve both a decorative function and to diffuse light.

[0068] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the length of the receiving cavity is matched with the length of the first reflector 2 along the first direction. This results in a smaller volume of the receiving cavity, which in turn makes the size of the light-blocking member 3 smaller, thus saving material consumption.

[0069] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the light-emitting surface is flush with the outer surface of the light-blocking member 3. In this way, the inner wall of the light entrance hole 32 can block the light emitted by the first light-emitting member 1 to a large extent.

[0070] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the three-zone structure 221 is located at the end of the first reflector 2 near the light-emitting surface along the first direction. Thus, the light entrance aperture 32 is relatively close to the three-zone structure 221 along the axial direction. It is understood that when at least a portion of the three-zone structure 221 is located on one side of the light entrance aperture 32 along the third direction, the closer the three-zone structure 221 is to the light entrance aperture 32, the greater the degree of obstruction by the light-blocking element 3, and the less likely light passing through the light entrance aperture 32 will reach the three-zone structure 221. By positioning the three-zone structure 221 at the end of the first reflector 2 near the light-emitting surface along the first direction, the illuminance value of the three-zone structure 221 is reduced, thereby making the three-zone light pattern more compatible with regulatory requirements.

[0071] Furthermore, the three-zone structure 221 is located in the area of ​​the first reflector 2 where the light-blocking element 3 has a large obstruction. This allows the portion of the first reflector 2 used to form the main low beam pattern to be located in the area where the light-blocking element 3 has a small obstruction. This results in a larger illuminance value for the portion used to form the main low beam pattern, which in turn results in a relatively large illuminance value for the main low beam pattern. Thus, even if the power of the first light-emitting element 1 is relatively small, the illuminance value of the main low beam pattern is still relatively large, resulting in better performance of the vehicle headlight lighting module.

[0072] Please refer to Figure 2 , Figure 3 and Figure 4 It is understood that, in the embodiments of this application, along the second direction, the light-emitting surface is located at the end of the first reflector 2 away from the light-emitting port 31. Generally, along the second direction, the light-inlet port 32 is also located at the end of the first reflector 2 away from the light-emitting port 31.

[0073] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, a surface protrusion on one side of the receiving cavity where the light entrance hole 32 is formed forms a light-blocking portion 33, which extends circumferentially along the light entrance hole 32. In this way, the light-blocking portion 33 can block the light emitted by the first light-emitting element 1 to a certain extent, thereby constraining the light and ensuring that as much of the light passing through the light entrance hole 32 as possible is reflected by the first reflecting mirror 2 before exiting from the light exit port 31. This reduces the amount of light that exits directly from the light exit port 31 without being reflected by the first reflecting mirror 2, which helps to better meet regulatory requirements for the near-beam shape.

[0074] Please refer to Figure 2 , Figure 3 and Figure 4 It is understood that, in the embodiments of this application, the surface of the receiving cavity on the side where the light inlet hole 32 is formed protrudes along the axial direction of the light inlet hole 32 toward the inside of the receiving cavity, forming a light blocking part 33. Along the axial direction of the light inlet hole 32, the light blocking part 33 is located on the side of the light inlet hole 32 closer to the inside of the receiving cavity.

[0075] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the length of the light-blocking portion 33 along the axial direction of the light entrance aperture 32 is 1 to 3 millimeters. This allows the light-blocking portion 33 to better constrain the light while minimizing light loss.

[0076] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the inner wall of the light-blocking part 33 is combined with the side wall of the light-entry hole 32. In this way, the light-blocking part 33 can block the light emitted by the first light-emitting element 1 to a greater extent, thus constraining the light and ensuring that as much of the light passing through the light-entry hole 32 as possible is reflected by the first reflecting mirror 2 before exiting from the light-exit port 31. Furthermore, the combination of the inner wall of the light-blocking part 33 and the side wall of the light-entry hole 32 reduces the bending of the inner surface of the receiving cavity, thereby helping to reduce stress concentration.

[0077] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this application, the inner sidewall of the light-blocking part 33 and the sidewall of the light-entry hole 32 are smoothly transitioned. For example, the inner sidewall of the light-blocking part 33 and the sidewall of the light-entry hole 32 are coplanar.

[0078] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the light-emitting surface faces upward. This upward orientation of the light-emitting surface causes the first reflector 2 to face downward, making it less likely for sunlight to directly hit the first reflector 2, thus reducing damage to the first reflector 2. Furthermore, since the headlight assembly is positioned relatively low to the human eye, when viewed from above, the first reflector 2 often has many bends and is not perfectly flat. The downward orientation of the first reflector 2 makes it less likely for people to observe it, resulting in a flatter surface for the parts of the headlight assembly that are more easily visible.

[0079] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the vehicle headlight illumination module further includes a light-blocking member 3, which forms a receiving cavity with a light-emitting port 31, the orientation of which is the same as the second direction. A first reflector 2 is disposed within the receiving cavity, facing the light-emitting port 31. The inner surface of the receiving cavity includes a decorative portion 34, at least a portion of which is formed on the bottom surface of the receiving cavity and located between the light-emitting port 31 and the first reflector 2.

[0080] Please refer to Figure 2 , Figure 3 and Figure 4 It is understandable that the light outlet 31 faces the front of the vehicle. The first reflector 2 is positioned opposite the light outlet 31 on one hand and opposite the upward-facing light-emitting surface on the other. That is, the first reflector 2 is tilted relatively vertically, and the lower end of the first reflector 2 is closer to the rear of the vehicle than the upper end. Along the length of the vehicle, the distance between the lower end of the first reflector 2 and the light outlet 31 is greater than the distance between the upper end of the first reflector 2 and the light outlet 31. At least a portion of the decorative part 34 is formed on the bottom surface of the receiving cavity and is located between the light outlet 31 and the first reflector 2. The large distance between the lower end of the first reflector 2 and the light outlet 31 allows for a larger length of the portion of the decorative part 34 formed on the bottom surface of the receiving cavity, making the decorative part 34 more prominent and easily observed by personnel. The position of the headlight device is relatively low to the human eye. When a person observes the headlight device from top to bottom, the fact that at least a portion of the decorative part 34 is formed on the bottom surface of the receiving cavity makes the decorative part 34 more prominent and easily observed by personnel.

[0081] Please refer to Figure 2 , Figure 3 and Figure 4In some embodiments of this application, the decorative portion 34 surrounds the first light-emitting element 1 circumferentially along the light outlet 31. This makes the decorative portion 34 more prominent and allows it to scatter more light.

[0082] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the decorative portion 34 extends from the light-emitting port 31 to the end of the first light-emitting element 1 away from the light-emitting port 31. Thus, the length of the decorative portion 34 is relatively large along the second direction, making the decorative portion 34 more prominent.

[0083] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, the decorative part 34 and the diffuse reflection part have the same structure. That is, the decorative part 34 serves a decorative function on the one hand, and can diffusely reflect the light emitted by the first light-emitting element 1 on the other hand.

[0084] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the vehicle headlight lighting module further includes a second light-emitting element and a second reflector 5. The light-emitting surface of the second light-emitting element faces upward, and the second reflector 5 is disposed opposite to the light-emitting surface. The second reflector 5 is configured to reflect the light emitted from the light-emitting surface into light along a second direction to form a high beam pattern.

[0085] In this way, with the light-emitting surface facing upwards, the second reflector 5 faces downwards, making it less likely for sunlight to directly hit the second reflector 5, thus reducing the risk of damage. Furthermore, since the second reflector 5 often has many bends and is not perfectly flat, its downward orientation makes it less visible to personnel, resulting in a smoother surface for the more easily observable parts of the vehicle's lighting system.

[0086] In this embodiment, please refer to the high beam pattern. Figure 7 The light pattern reference formed by the superposition of near beam and far beam patterns Figure 8 .

[0087] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the second reflector 5 and the first reflector 2 are separate structures. The vehicle lighting module also includes a high beam dimming mechanism, which is connected to the second reflector 5 in a transmission manner. It is configured to drive the second reflector 5 to move relative to the lamp housing 6. The widened reflector, the corner reflector and the second reflector 5 can move independently relative to the lamp housing 6, so that the relative positions of the high beam pattern, the widened beam pattern and the corner beam pattern are adjustable, which is beneficial to improving the quality of the beam pattern.

[0088] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the first reflector 2 and the second reflector 5 may be arranged along a second direction. Of course, in some embodiments of this application, the first reflector 2 and the second reflector 5 may be arranged along a third direction.

[0089] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the second reflector 5 includes at least two far-beam reflector units 51, and each far-beam reflector unit 51 is provided with a corresponding second light-emitting element. The light emitted by each second light-emitting element is reflected by the corresponding far-beam reflector unit 51 and the resulting light patterns are superimposed to form a far-beam light pattern.

[0090] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the second reflectors 5 may be arranged along a third direction. Of course, in some embodiments of this application, the second reflectors 5 may also be arranged along a second direction.

[0091] Please refer to Figure 1 and Figure 6 In some embodiments of this application, a fourth shielding portion is provided between each of the second reflectors 5. This reduces mutual interference of light at each of the second reflectors 5. In some embodiments of this application, the fourth shielding portion has parallel fifth convex strips extending along a second direction, a textured surface, and an aluminum-plated layer. This allows the fourth shielding portion to serve both a decorative function and to diffuse light.

[0092] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the various high beam reflector units 51 are fixedly connected. In this way, the high beam dimming mechanism can drive the various high beam reflector units 51 to move synchronously, which is convenient for adjustment.

[0093] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the vehicle headlight illumination module further includes a light-shielding member 7. The light-shielding member 7 forms a receiving cavity with a light-transmitting opening 71. The light-transmitting opening 71 faces the same direction as the second direction. The light-shielding member 7 forms a light-entry hole 72. The depth direction of the light-entry hole 72 is parallel to the first direction, and the light-entry hole 72 connects the inside and outside of the receiving cavity. A second reflector 5 is disposed within the receiving cavity, facing the light-transmitting opening 71. A light-emitting surface is disposed within the light-entry hole 72. In this way, the light-shielding member 7 can eliminate stray light, and the light-entry hole 72 can constrain the light, so that as much light as possible is reflected by the second reflector 5 before being emitted, which is beneficial to improving the quality of the high beam.

[0094] Please refer to Figure 1and Figure 6 In some embodiments of this application, the second reflector 5 may be a reflective layer covering the inner surface of the light-shielding member 7. This facilitates the formation of the second reflector 5. The reflective layer may be an aluminum-plated layer, and its reflectivity may be greater than 0.8.

[0095] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the portion of the inner surface of the accommodating cavity that avoids the second reflecting mirror 5 includes a diffuse reflective surface. This diffuse reflective surface can diffuse the light from the second light-emitting element, eliminating stray light and reducing light loss. In some embodiments of this application, the diffuse reflective surface has a sixth convex strip running side-by-side along a second direction, a textured surface, and an aluminum-plated layer. This allows the diffuse reflective surface to serve both a decorative function and to diffuse light.

[0096] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the length of the accommodating cavity is matched with the length of the second reflector 5 along the first direction. This results in a smaller volume of the accommodating cavity, which in turn makes the size of the light-shielding member 7 smaller, thus saving material consumption.

[0097] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the light-emitting surface is flush with the outer surface of the light-shielding member 7. In this way, the inner wall of the light-entry hole 72 can block the light emitted by the second light-emitting member to a large extent.

[0098] Please refer to Figure 1 and Figure 6 In some embodiments of this application, a light-shielding portion 73 is formed on the surface of the accommodating cavity on one side where the light inlet hole 72 is formed. The light-shielding portion 73 extends circumferentially along the light inlet hole 72 and axially along the light inlet hole 72. The length of the light-shielding portion 73 can be 1 to 3 millimeters. The inner sidewall of the light-shielding portion 73 can be combined with the sidewall of the light inlet hole 72. In some embodiments of this application, the inner sidewall of the light-shielding portion 73 and the sidewall of the light inlet hole 72 are smoothly transitioned. For example, the inner sidewall of the light-shielding portion 73 and the sidewall of the light inlet hole 72 are coplanar. In this way, the light-shielding portion 73 can block the light emitted by the second light-emitting element to a certain extent, thereby constraining the light and allowing the light passing through the light inlet hole 72 to be reflected by the second reflector 5 as much as possible before being emitted from the light outlet 71, which is beneficial to improving the quality of the high beam.

[0099] Please refer to Figure 1 and Figure 6In some embodiments of this application, the inner surface of the accommodating cavity includes a decorative surface 74. At least a portion of the decorative surface 74 is formed on the bottom surface of the accommodating cavity and is located between the light-transmitting port 71 and the second reflector 5. In some embodiments of this application, the decorative surface 74 extends from the light-transmitting port 71 to the end of the second light-emitting element away from the light-transmitting port 71. Thus, along the second direction, the length of the decorative surface 74 is relatively large, making the decorative surface 74 more prominent.

[0100] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the decorative surface 74 surrounds the second light-emitting element circumferentially around the light-transmitting opening 71. This makes the decorative surface 74 more prominent and allows it to scatter more light.

[0101] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the decorative surface 74 and the diffuse reflection surface have the same structure. That is, the decorative surface 74 serves a decorative function on the one hand, and diffuse reflection of the light emitted by the second light-emitting element on the other hand.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
