Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a vehicle lamp assembly and a vehicle having the same. Background Art

[0002] At present, the automobile industry is flourishing, and "car manufacturing" has become the hottest topic nowadays. Car manufacturers have also developed from several large state-owned enterprises to the current market structure of state-owned, private and new forces. The market competition is fierce, and only models with outstanding selling points and excellent performance can stand out. As one of the main highlights of the car, the lighting system is bound to attract much attention. Excellent lighting performance and good user experience have become one of the main directions for the future development of automotive lighting systems. As the most commonly used lighting function, the advantages and disadvantages of low beam lighting, especially in terms of illumination brightness, illumination width, power consumption and light efficiency, have always been the main focus of technical development.

[0003] In the prior art, the design of single low beam modules is mainly divided into two categories, direct projection + integral lens, reflective type + integral lens. The direct projection + integral lens is mainly that the light source is collimated by the light guide, and then emitted from the lens after passing through the cut-off line formed by the shielding piece made of opaque metal. The reflective type + integral lens is mainly that the light source is emitted through the reflective bowl, and then emitted from the lens after passing through the cut-off line formed by the shielding piece made of opaque metal. Both solutions have a common defect, that is, the light source will lose part or even half of the light energy after passing through the opaque shielding structure, which makes the current single low beam light efficiency low, about only 40%-60%, and if you want to increase the lighting brightness, you must increase the power, which leads to increased costs.

[0036] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0037] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0038] The following will refer to Figure 1-4 The utility model is described in detail in conjunction with the embodiments.

[0039] The present invention is described with the X direction as the longitudinal direction of the vehicle (i.e. the front-rear direction of the vehicle), the Y direction as the lateral direction of the vehicle (i.e. the left-right direction of the vehicle), and the Z direction as the vertical direction of the vehicle (i.e. the up-down direction of the vehicle).

[0040] The utility model provides a vehicle lamp assembly 100, referring to Figure 1-4 As shown, it includes PCBA1, light guide assembly 2, mounting frame 3 and lens 4; the mounting frame 3 has two parts extending in the vertical direction and the horizontal direction, the PCBA1 is a plate-like structure arranged on the mounting frame 3 extending in the vertical direction, and the PCBA1 includes a light source assembly 11 and a printed circuit board, wherein the PCBA (printed circuit board, Printed Circuit Board Assembly), that is, the PCBA1 of the utility model is a PCB (printed circuit board, Printed circuit board) formed by fixing and welding the light source assembly on the PCB through surface mounting technology or plug-in technology, etc. The light source assembly 11 can provide light energy for the illumination of the entire vehicle lamp assembly 100. In some examples, the light source assembly 11 is an LED, and the light source assembly 11 can include multiple LEDs, such as Figure 1 As shown, in some specific examples, the light source assembly 11 may include three LEDs, but the number of LEDs is not limited thereto, and may be configured accordingly based on the vehicle model to which it is adapted and specific usage requirements. Figure 1 Three LED light sources are shown for the purpose of illustration, but after reading the following technical solution, ordinary technicians can obviously understand that the solution can be applied to the technical solution of four or more lamp assemblies 100, which also falls within the scope of protection of the utility model. PCBA1 is an integrated circuit that provides LED particles and lighting for the lamp assembly 100. By setting PCBA1, the light source assembly 11 is integrated on a printed circuit board, realizing the integrated design of the electronic system, which not only reduces the design difficulty and shortens the R&D cycle, but also improves the reliability and stability of the entire electronic system. In addition, this integrated design is also conducive to reducing production costs and improving production efficiency.

[0041] The light guide component 2 is arranged on the part of the mounting frame 3 extending in the horizontal direction, and is fixed above the horizontal part of the mounting frame 3 so that the mounting frame 3 can fix and support the light guide component 2. The light guide component 2 is used to guide the light emitted by the light source component 11. By setting the light guide component 2, the light emitted by the light source component 11 can be converged to the inner surface of the lens 4, thereby improving the utilization rate of the light source.

[0042] The portion of the mounting frame 3 extending in the vertical direction is used to install the PCBA1, and the portion of the mounting frame 3 extending in the horizontal direction is used to install the light guide assembly 2. The portion of the mounting frame 3 extending in the horizontal direction is arranged below the light guide assembly 2, that is, the portion of the mounting frame 3 extending in the horizontal direction and abutting against the lower surface of the light guide assembly 2 has the same inclined trend as the lower surface of the light guide assembly 2. This arrangement enables the portion of the mounting frame 3 extending in the horizontal direction to partially block the light passing through the light guide assembly 2, thereby forming a low beam cutoff line. By setting the mounting frame 3 to block part of the light, thereby forming a light and dark area, and forming a light and dark cutoff line at the junction of light and dark, the illuminated area of ​​the vehicle lamp assembly 100 can meet the requirements of relevant standards.

[0043] The lens 4 is arranged on the side of the light guide assembly 2 away from the PCBA1, and the lens 4 is opposite to the light guide assembly 2 and is arranged at a distance, so that the light emitted by the PCBA1 is emitted to the lens 4 through the light guide assembly 2 and enters the inner surface of the lens 4. The lens 4 adopts a multi-curved composite structure, and the outer surface of the lens 4 is a free-style curved surface that can be changed with the shape. For different car models, the style of the outer surface of the lens 4 can be determined according to its overall shape, which increases the adaptability of the lens 4. The inner surface of the lens 4 is a composite curved surface that matches the corresponding outer surface in front for light distribution. Through this arrangement, the light emitted from the light guide assembly 2 can be refracted by the lens 4 and then emitted from the side of the lens 4 away from the PCBA1, and then a clear low beam cutoff line is formed through the lens imaging principle.

[0044] According to the vehicle lamp assembly 100 of the present invention, by providing PCBA 1, light guide assembly 2, mounting frame 3, and lens 4, the mounting frame 3 forms a low beam cutoff line, so that the vehicle lamp assembly 100 can meet relevant standards in the illuminated area while effectively saving the number of parts of the vehicle lamp assembly 100, thereby reducing the production cost of the vehicle lamp assembly 100. The present invention can also improve the low beam road illumination quality, enhance the illumination of some test areas, increase the road illumination width, and increase the road illumination area in front of the vehicle, thereby comprehensively improving the low beam performance.

[0045] Refer to the following Figure 1-Figure 4 Some embodiments of a vehicle lamp assembly 100 according to the present invention are described.

[0046] According to some embodiments of the present invention, Figure 1 As shown, the light guide assembly 2 includes a concentrator 21 and a light guide 22. The concentrator 21 is arranged on the mounting frame 3 and is located on the light-emitting side of the light source assembly 11. The concentrator 21 cooperates with the light source assembly 11 to converge light. That is, the concentrator 21 is arranged on the light incident surface of the light guide assembly 2. The concentrator 21 can converge the light source emitted by the PCBA1 and then emit it to the light guide 22. A light entrance hole is arranged on the concentrator 21. The light emitted by the light source assembly 11 can be converged to the side of the light guide 22 close to the concentrator 21 through the light entrance hole. Optionally, the number of concentrators 21 can be set corresponding to the number of LEDs. Figure 1 and Figure 3 In the example shown, the number of LEDs is 3, and three concentrators 21 corresponding to the three LEDs can be provided. Of course, the concentrators 21 are not limited to the following. Figure 1 and Figure 3 The three shown can be set to multiple. When the number of concentrators 21 is multiple, multiple concentrators 21 can be arranged horizontally on the mounting frame 3 along the same direction, that is, the concentrators 21 can be arranged horizontally along the Y direction, that is, the lateral direction of the vehicle. The concentrators 21 can be used to aggregate light to achieve a better lighting effect. The light guide 22 is matched with the concentrator 21, and the light guide 22 is set on the side of the mounting frame 3 away from the PCBA1. The contact surface of the light guide 22 and the mounting frame 3 has the same shape and trend as this part of the mounting frame 3, so that the light guide 22 can be set in a close relationship with the mounting frame 3, and at the same time, the structure between the components of the entire vehicle lamp assembly 100 is more compact, which can save the actual occupied space of the vehicle lamp assembly 100. Through this arrangement, the concentrator 21 is suitable for converging the light to one side of the light guide 22, and the light guide 22 guides the light to the side of the lens 4, thereby realizing the convergence and guidance of the light.

[0047] According to some embodiments of the present invention, Figure 2As shown, the light guide component 2 is provided with an incident surface 221, a first reflective surface 222, a second reflective surface 223 and an exit surface 224. The incident surface 221 cooperates with the condenser 21, that is, a side of the incident surface 221 close to the light source component 11 is connected to an end of the condenser 21 away from the light source component 11, and the light emitted by the light source component 11 can be converged by the condenser 21 and then emitted into the light guide component 22 through the incident surface 221. The first reflective surface 222 corresponds to at least a portion of the incident surface 221, and is used to reflect the light emitted from the incident surface 221 to the first reflective surface 222. The second reflection surface 223 is arranged opposite to the first reflection surface 222, and is used to reflect the light emitted to the second reflection surface 223 after being reflected by the first reflection surface 222; the light emitted to the second reflection surface 223 after being reflected by the first reflection surface 222 can be reflected twice by the second reflection surface 223, thereby changing the emission direction of the light, so that the light emitted to the second reflection surface 223 can be emitted through the emission surface 224. At least part of the emission surface 224 is arranged opposite to the second reflection surface 223, and the light emitted to the emission surface 224 through the second reflection surface 223 is emitted from the emission surface 224; the emission surface 224 is arranged in the direction of the light guide 22 close to the lens 4, and at least part of the emission surface 224 is arranged opposite to the second reflection surface 223, so that the light emitted from the second reflection surface 223 to the emission surface 224 can be emitted through the emission surface 224 and enter the inner surface of the lens 4. This arrangement allows the light that has been converged by the concentrator 21 to enter the light guide 22, and then pass through the first reflection surface 222 or the second reflection surface 223 to be emitted toward the exit surface 224, and then be emitted from the exit surface 224. The light that has been converged by the concentrator 21 to enter the light guide 22 can also be reflected by the first reflection surface 222 and then enter the second reflection surface 223, and then be reflected from the second reflection surface 223 to the exit surface 224 and then be emitted.

[0048] According to the light guide 22 of the utility model, by setting the incident surface 221, the first reflection surface 222, the second reflection surface 223, and the exit surface 224, the light converged by the concentrator 21 can be reflected by the first reflection surface 222 and the second reflection surface 223 after entering the light guide 22 through the incident surface 221, so that the original exit direction of the incident light is changed due to multiple reflections, that is, the light can be more incident to the inner surface of the lens 4 through the exit surface 224, thereby reducing the loss of light energy and effectively improving the light efficiency without changing the power.

[0049] According to some embodiments of the present invention, Figure 2As shown, the angle α between the incident surface 221 and the first reflecting surface 222 is α, and satisfies the relationship: 30°≤α≤60°; the angle α between the incident surface 221 and the first reflecting surface 222 satisfies the relationship: 30°≤α≤60°. When the angle α satisfies the above angle range, the light can be utilized with high efficiency, and the light will be refracted by the first reflecting surface 222. Therefore, when the angle α between the incident surface 221 and the first reflecting surface 222 is 30°≤α≤60°, the light incident through the incident surface 221 can be reflected by the first reflecting surface 222, that is, by setting the angle α between the incident surface 221 and the first reflecting surface 222 as above, and satisfying the relationship: 30°≤α≤60°, the light converged by the concentrator 21 can be reflected by the first reflecting surface 222 after passing through the incident surface 221 to the first reflecting surface 222, thereby improving the utilization efficiency of light energy. Preferably, the angle α between the incident surface 221 and the first reflective surface 222 is 45°. When the angle α between the incident surface 221 and the first reflective surface 222 is 45°, the first reflective surface 222 can reflect the light in the vertical direction. This setting has high reflection efficiency and does not cause light deviation or distortion, thereby reducing the loss of light energy. The angle between the incident surface 221 and the second reflective surface 223 is β, and satisfies the relationship: 120°≤β≤150°. When α and β both meet this angle range, when the light converged by the concentrator 21 passes through the incident surface 221 and is incident on the first reflective surface 222 and then reflected to the second reflective surface 223, the light incident through the second reflective surface 223 can be completely reflected by the second reflective surface 223. Optionally, when α satisfies the relationship: 30°≤α≤60° or β satisfies the relationship: 120°≤β≤150°, when the light converged by the concentrator 21 passes through the incident surface 221 and is incident on the first reflective surface 222 and then is reflected on the second reflective surface 223, the light incident through the second reflective surface 223 can be reflected by the second reflective surface 223. The angle between the incident surface 221 and the second reflective surface 223 of the utility model is β, and satisfies the relationship: 120°≤β≤150°, so that the light converged by the concentrator 21 passes through the incident surface 221 and is incident on the first reflective surface 222 and then is reflected on the second reflective surface 223, and can be reflected by the second reflective surface 223, thereby greatly improving the utilization efficiency of light energy. Preferably, the angle α between the incident surface 221 and the second reflecting surface 223 is 135°. When the angle α between the incident surface 221 and the second reflecting surface 223 is 135°, the second reflecting surface 223 can reflect the light in a vertical direction. This setting has high reflection efficiency and will not cause light deviation or distortion, which can effectively reduce the loss of light energy.

[0050] According to some embodiments of the present invention, Figure 2As shown, the first reflection surface 222 is arranged in parallel with the second reflection surface 223. In this case, after the light enters from the first reflection surface 222, it will be reflected back in a direction parallel to the second reflection surface 223, that is, the reflection angles of the light on the first reflection surface 222 and the second reflection surface 223 are equal. This arrangement can make the direction of the light after passing through the first reflection surface 222 and the second reflection surface 223 more consistent, thereby reducing the scattering and loss of light, and improving the light efficiency without increasing the cost. The incident surface 221 and the exit surface 224 are arranged in parallel, that is, the distance between the incident surface 221 and the exit surface 224 arranged in parallel is equal, and the directions of the incident surface 221 and the exit surface 224 are the same. Through this arrangement, the propagation direction of the light gathered by the concentrator 21 can be kept unchanged, thereby ensuring the accuracy of the light. This arrangement can also reduce the volume of the optical component, reduce the manufacturing cost and be more suitable for different car models. Optionally, if only the incident surface 221 and the exit surface 224 of the lamp assembly 100 are arranged in parallel, the light rays gathered by the concentrator 21 can enter from the incident surface 221 and then pass through the light guide 22 in a straight line and exit from the exit surface 224. Optionally, if only the first reflection surface 222 and the second reflection surface 223 of the lamp assembly 100 are arranged in parallel, the light rays gathered by the concentrator 21 will not be deflected when they are emitted from the first reflection surface 222 to the second reflection surface 223, thereby reducing the loss of light energy. Optionally, if the incident surface 221 and the exit surface 224 of the lamp assembly 100 are arranged in parallel and the first reflection surface 222 and the second reflection surface 223 are arranged in parallel, then the light guide 22 is in the shape of a parallelogram, and such an arrangement can make all the light rays entering from the incident surface 221 be reflected and exit from the exit surface 224, thereby improving the utilization efficiency of light energy.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the mounting frame 3 includes: a first mounting plate 31, a second mounting plate 32, an extension plate 33 and a support plate 34. The first mounting plate 31 is arranged vertically and is used to install the plate-shaped PCBA1 so that the light-emitting surface of the plate-shaped PCBA1 faces the horizontal direction; that is, the first mounting plate 31 is arranged along the Z direction, that is, the vertical direction of the vehicle, and PCBA1 is installed on one side of the first mounting plate 31 close to the lens 4. A light source assembly 11 is provided on PCBA1 for emitting light. This arrangement allows the light emitted by the light source assembly 11 on PCBA1 to be aggregated by the light guide assembly 2, thereby achieving the purpose of simplifying the number of components of the vehicle lamp assembly 100 and reducing the volume of the vehicle lamp assembly 100, so as to better meet the needs of automobile users.

[0052] The second mounting plate 32 extends in the horizontal direction and one end is connected to the first mounting plate 31. The second mounting plate 32 can be used to install the light guide component 2. The second mounting plate 32 is vertically arranged with the first mounting plate 31, and one end of the second mounting plate 32 away from the first mounting plate 31 extends horizontally toward the lens 4. Such an arrangement enables the second mounting plate 32 to support the light guide component 2 installed thereon.

[0053] The second mounting plate 32 includes an extension plate 33 and a support plate 34. One end of the extension plate 33 is connected to the first mounting plate 31, and the other end of the extension plate 33 extends toward the lens 4. The extension plate 33 is located below the condenser 21, and the extension plate 33 and the condenser 21 have equal lengths in the direction toward the lens 4. This arrangement allows the light guide assembly 2 to have sufficient space above the extension plate 33 to install the condenser 21. The end of the extension plate 33 close to the lens 4 is connected to the condenser 21 to support and fix the condenser 21.

[0054] One end of the support plate 34 is connected to the end of the extension plate 33 close to the lens 4, that is, the side of the support plate 34 away from the lens 4 is connected to the side of the extension plate 33 close to the lens 4, and the other end of the support plate 34 is against the lens 4. The support plate 34 can be used to install the light guide 22. The plane of the light guide 22 connected to the support plate 34 constitutes the first reflection surface 222. In some examples, the shape of the support plate 34 is consistent with the shape of the first reflection surface 222, so that the first reflection surface 222 of the light guide 22 can be supported on the support plate 34. On the first reflective surface 222, the support plate 34 provides an upward support force to the light guide 22, and part of the support plate 34 is arranged to protrude from the exit surface 224 to the side of the lens 4 to form a low-beam cut-off line. In the direction toward the lens 4, the support plate 34 has a part that protrudes forward from the light guide 22 and extends upward. The part of the support plate 34 that protrudes from the exit surface 224 can block part of the light to form a low-beam cut-off line, that is, after the light shielding plate is set in the shape of a cut-off line, a clear low-beam cut-off line is finally formed through the imaging principle of the lens 4. By setting the support plate 34 of the mounting frame 3 to form a low-beam cut-off line, it is achieved that the overall structural design of the light assembly 100 can be more concise while achieving the low-beam cut-off line of the light assembly 100, reducing the use of parts and effectively reducing production costs.

[0055] According to some embodiments of the present invention, Figure 1As shown, the support plate 34 includes: a first support surface 341 and a second support surface 342. The first support surface 341 extends upwardly at an angle and is arranged in close contact with the lower surface of the light guide 22, that is, the first support surface 341 has the same shape and trend as the lower surface of the light guide surface. This arrangement can make the surface of the light guide 22 smoother, thereby improving the reflectivity of the light guide 22 and making the light of the LED lamp aggregated by the concentrator 21 more uniform. The support plate 34 can support the light guide 22 through the first support surface 341 that is arranged in close contact with the lower surface of the light guide 22, so that the light guide 22 can be firmly fixed on the support plate 34. The upper surface of the first support surface 341 and the lower surface of the light guide 22 are arranged in close contact with each other, which can effectively save the volume occupied by the entire vehicle lamp assembly 100, and the overall structure can also be more stable. The supporting surface 342 extends from the first supporting surface 341 toward the side of the lens 4 and is arranged perpendicular to the exit surface 224, that is, the side of the second supporting surface 342 close to the first mounting plate 31 is connected to the side of the first supporting surface 341 away from the first mounting plate 31, and the side of the second supporting surface 342 away from the first supporting surface 341 faces the side of the lens 4 and extends toward the lens 4. The second supporting surface 342 is arranged perpendicular to the exit surface 224, so that it can support the exit surface 224, and the second supporting surface 342 can form a low beam cut-off line, so that when the light of the car headlights is irradiated to the ground, the brightness of the light is gradually reduced within a certain range after reflection, forming an obvious light-dark dividing line, thereby meeting national regulations and safety requirements.

[0056] According to some embodiments of the present invention, Figure 3 As shown, the second supporting surface 342 includes a first step surface 5, a transition surface 6 and a second step surface 7 which are sequentially connected in a first direction. The first direction is the Y direction of the vehicle, that is, the second supporting surface 342 includes a first step surface 5, a transition surface 6 and a second step surface 7 which are sequentially connected in the Y direction of the vehicle. In the vertical direction, that is, the Z direction of the vehicle, the first step surface 5 is optionally higher than the second step surface 7. Such an arrangement can achieve that when light is emitted through the light guide 22, it can be blocked by the first step surface 5 and the second step surface 7 with a height difference when passing through the second supporting surface 342, thereby forming an asymmetric light surface with different distances on the ground. The first step surface 5 and the second step surface 7 are arranged in parallel, that is, the upper surfaces of the first step surface 5 and the second step surface 7 are parallel in the Z direction of the car, and the transition surface 6 is connected between the first step surface 5 and the second step surface 7 and extends obliquely. This arrangement can achieve the road effect of the lamp assembly 100 with low light on the left and high light on the right. When the low beam is turned on, an asymmetric light shape will be formed on the road directly in front of the car headlight, thereby avoiding affecting the field of vision of drivers of oncoming vehicles.

[0057] According to some embodiments of the present invention, Figure 1As shown, the second support surface 342 is coplanar with the light source assembly 11, that is, the second support surface 342 is located at the same height position as the light emitting center point of the light source assembly 11 in the Z direction of the vehicle. This arrangement can realize that the part of the light emitted by the light source assembly 11 above the second support surface 342 can be completely emitted to the inner side of the lens 4 through the exit surface 224, and the part of the light emitted by the light source assembly 11 below the second support surface 342 can be reflected by the first reflection surface 222 and the second reflection surface 223 in the light guide 22, and the original light direction is changed, and it can also be emitted to the inner side of the lens 4 through the exit surface 224. By setting the second support surface 342 and the light source assembly 11 coplanar, the blocked light energy can be fully utilized, the utilization rate of the light source is improved, the light efficiency is improved when the power remains unchanged, and the performance of the low beam can be comprehensively improved.

[0058] According to some embodiments of the present invention, Figure 1 As shown, the mounting frame 3 is provided with a heat sink 8, and the heat sink 8 is arranged on the first mounting plate 31 and is located on the side of the first mounting plate 31 away from PCBA1, that is, the heat sink 8 is arranged on the side of the mounting frame 3 where PCBA1 is not installed and away from the lens 4, and the heat sink 8 is arranged in a comb shape on the back of the mounting frame 3. This arrangement can dissipate the heat generated by the light emission of PCBA1 through the heat sink 8. The heat sink 8 is arranged in a comb shape on the side of the mounting frame 3 away from PCBA1, which can provide more surface area to contact the air, effectively improving the heat dissipation efficiency, and this design can also achieve temperature reduction without using a fan to keep the lamp assembly 100 cool, effectively reducing the manufacturing cost and avoiding the noise caused by the use of a fan.

[0059] According to some embodiments of the present invention, Figure 4 As shown, the lens 4 includes: a first light-transmitting portion 41, which is arranged opposite to the exit surface 224 of the light guide 22 and is used to guide the light. The first light-transmitting portion 41 can guide the light passing through the light guide 22 downward, that is, the first light guide can refract the light to one side of the road surface, so that the light emitted by the PCBA1 is projected onto the ground, thereby realizing the lighting function of the vehicle lamp assembly 100 on the ground; a second light-transmitting portion 42, which is connected to the first light-transmitting portion 41 and arranged in the vertical direction, and the second light-transmitting portion 42 is connected to the light guide 22. The exit surface 224 of 22 is arranged relatively and is used to guide the light, that is, the second light-transmitting portion 42 can also refract the light downward to the road surface. The light patterns formed on the ground after being guided by the first light-transmitting portion 41 and the second light-transmitting portion 42 can partially overlap. The lens 4 adopts a multi-curved composite structure, the outer surface is a free-style curved surface that can change with the shape, and the inner surface is a composite curved surface that matches the corresponding outer surface in front for light distribution. This arrangement can enhance the illumination quality of the low-beam road surface, enhance the width of the road lighting, reduce the dark area in front of the vehicle, and comprehensively improve the performance of the low beam.

[0060] According to the utility model, the vehicle is provided with a corresponding headlight assembly 100, so that the vehicle can form a low-beam cutoff line according to the headlight assembly 100 of the utility model by making the mounting frame 3 form a low-beam cutoff line, so that the headlight assembly 100 can meet the relevant standards while effectively saving the number of parts of the headlight assembly 100, reducing the production cost of the headlight assembly 100, and also improving the light efficiency of the headlight assembly 100. The utility model can also improve the low-beam road illumination quality, enhance the illumination of part of the test area, increase the road illumination width, and increase the road illumination area in front of the vehicle, and comprehensively improve the low-beam performance.
