Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, specifically to ADB and auxiliary high beam modules. Background Technology

[0002] With the increasing number of cars on the road, traffic accidents have also risen, some of which are caused by improper use of high beams. The market demand for intelligent driving assistance functions is growing, leading to the development of an adaptive high beam system—ADB (Adaptive Driving Beam). ADB is an intelligent high beam control system that adaptively changes the high beam pattern according to road conditions. Based on the vehicle's driving status, environmental conditions, and road traffic conditions, the ADB system automatically turns the high beams on or off for the driver. Simultaneously, based on the position of vehicles in the driver's field of vision, it adaptively changes the pixels of one or more units in the high beam pattern to avoid dazzling other road users.

[0003] During driving, a car generates a lot of dust due to airflow. In complex weather conditions, especially at night, the external environment contains a lot of moisture. During nighttime driving, it is necessary to continuously introduce external airflow to cool the lights. This airflow contains dust and moisture. After prolonged use, the cooling fins of the lights become covered with clumps of dust, which affects the cooling efficiency of the fins. This prevents the large amount of light generated during operation from dissipating in time. In addition, the vibrations during driving can cause the LED chips to detach from the solder joints. Summary of the Invention

[0004] The purpose of this invention is to provide an ADB and auxiliary high beam module to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an ADB and auxiliary high beam module, including a lamp assembly, wherein a dust removal mechanism and a dehumidification mechanism are provided on one side of the lamp assembly, the lamp assembly includes a fan, a lens, a light shield, an ADB concentrator, a lamp panel, a fairing, a decorative ring and a housing, and the fan is installed inside the fairing;

[0006] The dust removal mechanism is installed on one side of the fan, and the dehumidification mechanism is installed inside the dust removal mechanism. The dust removal mechanism includes a grid and a rotating shaft. A scraper is installed on the outer wall of the grid. The fixed end of the rotating shaft is connected to a guide shroud, and the output end of the rotating shaft is connected to the grid. A limit plate is installed inside the grid, and a dehumidification mechanism is arranged around the outer side of the limit plate. The dehumidification mechanism includes a water absorption plate. A flexible water-absorbing material is installed on the side of the water absorption plate near the grid, and the water absorption plate is slidably connected to the grid. A heat-conducting plate is installed on one side of the lamp panel, and a guide shroud is installed on one side of the heat-conducting plate. The air guide shroud contains a fan, and a dust removal mechanism is installed on one side of the fan. The heat dissipation fins on the heat conduction plate are designed in a Y-direction. Notches are opened at both ends of the air guide shroud, so that the air blown out by the fan forms an airflow between the heat dissipation fins. The airflow covers the back of the air guide plate. The airflow inside the air guide shroud moves from the side where the dust removal mechanism is located to the heat conduction plate. The lamp panel generates a lot of heat during operation. The fan rotation creates a continuous airflow on one side of the heat conduction plate. As the airflow passes over the heat conduction plate, it continuously absorbs heat from the heat conduction plate, thus dissipating heat from the lamp panel during operation.

[0007] Furthermore, the absorbent plate is equipped with several protrusions, each with a groove. The absorbent plate is connected to the grid via a spring. The protrusions are used to clean the grid. The straight-line distance between the tip of the protrusion and the rotating shaft is equal to the inner diameter of the grid. The protrusions are in contact with a limiting plate, which is used to change the straight-line distance between the protrusions and the rotating shaft. The protrusions are used to cooperate with the grid, which has several through holes. The positions of the protrusions match the positions of the through holes, and each protrusion has a groove. This design allows water inside the absorbent plate to leave the grid through the gap between the through holes and the grooves on the protrusions when the relative distance between the absorbent plate and the grid is reduced. The absorbent plate and the grid are slidably connected. The grid is annular, with side plates at both ends. The side plates are circular, and each side plate has a groove for sliding the absorbent plate. This facilitates the sliding connection between the absorbent plate and the side plate. The direction of the groove coincides with the radius of the circular side plate. Since the absorbent plate is connected to the grid by a spring, it is normally separated from the grid.

[0008] Furthermore, the grid has several through holes, the inner wall size of which matches the outer wall size of the spikes. Side plates are installed at both ends of the grid, and grooves are formed on the side plates. These grooves are connected to the water-absorbing plate via springs. An isolation net is installed on the side plates. A support plate is installed between the rotating shaft and the guide hood, and the outer wall of the isolation net is in contact with the outer wall of the support plate. Because the airflow inside the guide hood moves from the side where the dust removal mechanism is located to the heat-generating plate, during heat dissipation, outside air needs to pass through the dust removal mechanism before entering the guide hood. The grid is located at the inlet end of the guide hood, and the outside airflow needs to be filtered by the grid before entering the guide hood. The grid has several through holes, which are the air inlets of the grid. The inner wall size of the through holes matches the outer wall size of the spikes. The water-absorbing plate is normally separated from the grid. When the water-absorbing plate is subjected to external force... In operation, the absorbent plate engages with the grid, and the protrusions penetrate into the through holes, pushing out dust and impurities confined to one side of the grid. Since a scraper is installed on the outer wall of the grid, and the rotating shaft drives the grid to rotate, the scraper cleans the pushed-out dust and impurities. A support plate is installed between the guide shroud and the rotating shaft. The support plate is inclined, and one side surface of the support plate is in contact with one side surface of the side plate. Since the fixed end of the rotating shaft is connected to the guide shroud, and the output end of the rotating shaft is connected to the grid, the rotation of the grid by the rotating shaft creates relative movement between the support plate and the side plate, thereby achieving the effect of the support plate cleaning dust from the outer wall of the side plate. The isolation net is circular, with the rotating shaft passing through the center of the circular ring. The outer diameter of the isolation net is smaller than the circumference diameter of the absorbent plate. Several spokes are provided in the center of the side plate, connecting the two ends of the side plate, and the spokes are alternately connected to the through holes.

[0009] Furthermore, the limiting plates are disposed on both sides inside the grid. The limiting plates are fan-shaped, and the limiting plates are closer to the side where the fan is located. The straight-line distance between the two ends of the limiting plates and the rotation axis is greater than the straight-line distance between the middle of the limiting plates and the rotation axis. The output end of the rotation axis is connected to the grid. Since support plates are provided on both sides of the grid, the fixed end of the rotation axis is connected to one of the support plates. A through column is connected to the middle of the limiting plate. The through column connects the limiting plate to the support plate on the other side through a through side plate. This ensures that the limiting plates remain in a fixed state relative to the air guide plate during the rotation of the grid, indicating that the angle between the air guide and the limiting plates is relatively fixed. The limiting plates are fan-shaped and closer to the side where the fan is located. Due to the structure of the outer surface of the limiting plates, the distance between each area on the outer wall of the limiting plates and the rotation axis is not the same. The straight-line distance between the two ends of the limiting plates and the rotation axis is greater than the straight-line distance between the middle of the limiting plates and the rotation axis. The two end areas of the limiting plates and the middle area of ​​the limiting plates are connected by a curved transition.

[0010] Furthermore, the straight-line distance between the middle of the limiting plate and the rotating shaft is equal to the radius of the protrusion in the circumferential state, and the thickness of the limiting plate is less than the length of the rotating shaft. Since the straight-line distance between the two ends of the limiting plate and the rotating shaft is greater than the straight-line distance between the middle of the limiting plate and the rotating shaft, the absorbent plates are distributed in a ring around the rotating shaft on the inner side of the grid. When the absorbent plates move to the middle area of ​​the limiting plate in motion, the outer wall of the flexible absorbent material of the absorbent plate adheres to the inner wall of the grid under the action of the limiting plate, so that the airflow entering the guide plate needs to pass through the flexible absorbent material and the grid in sequence. During the airflow passing through the flexible absorbent material, the airflow dehumidification effect is achieved. When the absorbent plates move to contact the two ends of the limiting plate, the inner wall of the grid adheres to the outer wall of the absorbent plates, and the flexible absorbent material is squeezed by the grid and the absorbent plates. At this time, the flexible absorbent material inside the absorbent plates is... In the compression state, the protrusions on the outer wall of the absorbent plate extend from the flexible absorbent material and penetrate into the through holes, pushing out dust and impurities inside the through holes. When the flexible absorbent material inside the absorbent plate is being squeezed, the water inside the flexible absorbent material is squeezed out. Under the pressure of the absorbent plate, the water inside the absorbent plate leaves the grid through the gap between the through holes and the grooves on the protrusions. The leaving water comes into contact with the dust and impurities on the outside of the grid, achieving the dust reduction effect. When the absorbent plate is not in contact with the limiting plate, the absorbent plate, under the action of the spring, separates the flexible absorbent material on one side of the absorbent plate from the grid, and the outside air directly enters the inside of the grid through the through holes. When the absorbent plate inside the grid is in contact with the limiting plate, under the action of the spring, the absorbent plate is separated from the inner wall of the grid, and the outside airflow does not need to pass through the absorbent plate to enter the inside of the grid.

[0011] Furthermore, the lens surface is provided with micro-patterns, which are vertical dark stripes. The light-emitting surface of the lens is an irregularly shaped inclined surface, and the light-incident surface of the lens is a plurality of connected curved surfaces. The micro-patterns are used to weaken the vertical dark stripes between each pixel of ADB, so as to make the optical uniformity transition uniform. The shape of the micro-patterns is a regular quadrilateral, which ensures the diffusion angle of each pixel of ADB, so that the vertical stripes between each pixel of ADB are uniformly transitioned. The light-incident surface of the lens is three consecutive curved surfaces. The middle curved surface assists in receiving the light pattern of ADB, and the curved surfaces on both sides assist in receiving the light pattern of auxiliary far beam. The area of ​​the middle curved surface is larger than the area of ​​the curved surfaces on both sides.

[0012] Furthermore, the light-shielding plate is provided with a toothed structure, and there are several light-shielding plates. Vertical walls are provided between the light-shielding plates, and the two sides of the light-shielding plates are flanged. The toothed structure on the light-shielding plate is used to shield stray light generated during ADB operation. Two vertical walls are provided in the middle of the light-shielding plate to separate the auxiliary high beam unit and the ADB unit, preventing internal light crosstalk. The flanged structures on both sides of the light-shielding plate are used to shield the light pattern below the auxiliary high beam, thus allowing the high beam light pattern and the ADB light pattern to be better superimposed. The vertical walls of the light-shielding plate have equilateral triangular structures with an included angle of 87° and a height of 2.2mm. The equilateral triangular structures are used to weaken stray light. The light-shielding plate has two structures that shield the auxiliary high beam light pattern; one side is an arc-shaped structure, and the other side is a rectangular structure, used to filter the light pattern below the auxiliary high beam.

[0013] Furthermore, one side surface of the ADB concentrator is provided with a wave structure, and several LED beads are provided on the lamp panel. Two LED beads on one side are connected in series. The wave structure on one side surface of the ADB concentrator is used to smoothly transition the outer edge of the ADB light pattern. There are three light-emitting units on the lamp panel: auxiliary high beam units on both sides and the ADB light-emitting unit in the middle. The ADB light-emitting unit on the lamp panel has 13 LEDs arranged in a straight line. Each LED has an individual duty cycle current to control, and each LED can control its current independently. The two outermost LEDs are connected in series and controlled through a channel. The series connection of the two outermost LEDs makes the duty cycle current of the two outermost LEDs consistent. By controlling the two outermost LEDs simultaneously, the outer angle of the ADB light pattern is wider, and the transition between the dark and bright areas is more uniform. The auxiliary high beam A light-emitting unit is located to the upper left of the ADB light-emitting unit, and the auxiliary high beam B light-emitting unit is located to the lower right of the ADB light-emitting unit. The lamp panel is at a 26° angle to the vehicle mounting direction, further improving optical efficiency.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. This ADB and auxiliary high beam module, through the setting of grid, rotating shaft and scraper, increases the air intake area to reduce the filtration intensity of the air intake area. At the same time, isolation nets are set at both ends of the grid. The isolation nets are made of the same material as the grid. The grid, together with the rotating shaft, realizes the relative movement between the outer wall of the grid and the scraper and support plate, thereby achieving the effect of active cleaning of the outer wall of the grid, increasing the dust removal area outside the fan, and reducing the airflow resistance when passing through the grid.

[0016] 2. This ADB and auxiliary high beam module, through the setting of the water absorption plate, the water absorption plate is set at the air intake port of the fan, so that the air inside the external environment must pass through the water absorption plate before entering the fan. The water absorption plate dehumidifies the airflow, preventing moisture and dust from forming clumps on the heat dissipation fins, which would affect the heat dissipation efficiency of the heat dissipation fins. At the same time, it reduces the moisture inside the airflow, preventing the heat dissipation fins from being in a high moisture environment for a long time, which would cause the heat dissipation fins to be oxidized and corroded.

[0017] 3. This ADB and auxiliary high beam module, through the setting of the limiting plate and the setting of the outer surface structure of the limiting plate, changes the engagement state of the water absorption plate and the grid in each area. At the air inlet of the fan, the water absorption plate is controlled to be in contact with the grid to achieve dehumidification of the passing airflow. On one side of the air inlet of the fan, the water absorption plate is controlled to be in contact with the grid to achieve the purpose of squeezing the water absorption plate to remove water, and at the same time cleaning the impurities in the grid through holes.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8 The present invention provides a technical solution: an ADB and auxiliary high beam module, including a lamp assembly, a dust removal mechanism and a dehumidification mechanism are provided on one side of the lamp assembly, the lamp assembly includes a fan 1, a lens 11, a light shield 12, an ADB concentrator 7, a lamp panel 14, a diffuser 15, a decorative ring and a housing, and the fan 1 is installed inside the diffuser 15;

[0030] The dust removal mechanism is installed on one side of the fan 1, and the dehumidification mechanism is installed inside the dust removal mechanism. The dust removal mechanism includes a grid 2 and a rotating shaft 3. A scraper 4 is installed on the outer wall of the grid 2. The fixed end of the rotating shaft 3 is connected to the guide shroud 15, and the output end of the rotating shaft 3 is connected to the grid 2. A limit plate 5 is installed inside the grid 2, and a dehumidification mechanism is arranged around the outer side of the limit plate 5. The dehumidification mechanism includes a water absorption plate 6. A flexible water-absorbing material is installed on the side of the water absorption plate 6 near the grid 2. The water absorption plate 6 is slidably connected to the grid 2. By increasing the air intake area, the filtration intensity of the air intake area is reduced. At the same time, isolation nets are set at both ends of the grid 2. The isolation nets are made of the same material as the grid 2. The grid 2, in conjunction with the rotating shaft 3, enables the outer wall of the grid 2 to move relative to the scraper 4 and the support plate, thereby achieving the effect of active cleaning of the outer wall of the grid 2, increasing the dust removal area outside the fan 1, and reducing the airflow resistance during the passage of the grid 2.

[0031] The water-absorbing plate 6 is equipped with several protrusions 601, and several grooves are opened on the protrusions 601. The water-absorbing plate 6 is connected to the grid 2 by a spring. The protrusions 601 are used to clean the grid 2. The straight distance between the tip of the protrusion 601 and the rotating shaft 3 is equal to the inner diameter of the grid 2. The protrusions 601 are in contact with the limiting plate 5. The limiting plate 5 is used to change the straight distance between the protrusions 601 and the rotating shaft 3.

[0032] The grid 2 has several through holes 201. The inner wall size of the through holes 201 matches the outer wall size of the spikes 601. Side plates are installed at both ends of the grid 2. The side plates have grooves. The grooves are connected to the water-absorbing plate 6 by springs. An isolation net is installed on the side plates. A support plate is installed between the rotating shaft 3 and the guide shroud 15. The outer wall of the isolation net is in contact with the outer wall of the support plate. The water-absorbing plate 6 is located at the air intake port of the fan 1, so that the air from the outside environment must pass through the water-absorbing plate 6 to enter the fan 1. The water-absorbing plate 6 dehumidifies the airflow, preventing moisture and dust from forming clumps on the heat dissipation fins, which would affect the heat dissipation efficiency of the heat dissipation fins. At the same time, it reduces the moisture inside the airflow, preventing the heat dissipation fins from being in a high-moisture environment for a long time, which would cause the heat dissipation fins to be oxidized and corroded.

[0033] The limiting plate 5 is set on both sides inside the grid 2. The limiting plate 5 is fan-shaped. The limiting plate 5 is closer to the side where the fan 1 is located. The straight distance between the two ends of the limiting plate 5 and the rotating shaft 3 is greater than the straight distance between the middle of the limiting plate 5 and the rotating shaft 3.

[0034] The straight-line distance between the middle of the limiting plate 5 and the rotating shaft 3 is equal to the radius of the protrusion 601 in the surrounding state. The thickness of the limiting plate 5 is less than the length of the rotating shaft 3. The setting of the outer surface structure of the limiting plate 5 changes the meshing state of the water absorption plate 6 and the grid 2 in each area. At the air inlet of the fan 1, the water absorption plate 6 is controlled to be in contact with the grid 2 to achieve dehumidification of the passing airflow. On one side of the air inlet of the fan 1, the water absorption plate 6 is controlled to mesh with the grid 2 to achieve the purpose of squeezing the water absorption plate 6 to remove water, and at the same time cleaning the impurities in the through hole 201 of the grid 2.

[0035] The surface of lens 11 is provided with micro-patterns, which are vertical dark stripes. The light-emitting surface of lens 11 is an irregularly shaped inclined surface, and the light-incident surface of lens 11 is a plurality of connected curved surfaces.

[0036] The light-shielding plate 12 is provided with a toothed structure, and there are several light-shielding plates 12. A vertical wall is provided between the light-shielding plates 12, and the two sides of the light-shielding plate 12 are provided with flanges.

[0037] The ADB condenser 7 has a wave-like structure on one side surface, and the lamp panel 14 has several LED beads, with two LED beads on one side connected in series.

[0038] The working principle of the present invention is as follows: A heat-conducting plate is installed on one side of the lamp plate 14, and a flow guide shroud 15 is installed on one side of the heat-conducting plate. A fan 1 is installed inside the flow guide shroud 15, and a dust removal mechanism is installed on one side of the fan 1. The heat dissipation fins on the heat-conducting plate are designed in a Y direction. Notches are opened at both ends of the flow guide shroud 15 so that the air blown out by the fan 1 forms an airflow between the heat dissipation fins. The airflow covers the back of the flow guide plate. The airflow inside the flow guide shroud 15 moves from the side where the dust removal mechanism is located to the heat-conducting plate.

[0039] The lamp panel 14 generates a lot of heat during operation. The rotation of the fan 1 causes a continuous airflow to form on one side of the heat-conducting plate. As the airflow passes through the heat-conducting plate, it continuously absorbs heat from the heat-conducting plate, thus dissipating heat from the lamp panel 14 during operation.

[0040] The spikes 601 are used to cooperate with the grid 2. The grid 2 is provided with several through holes 201. The position of the spikes 601 matches the position of the through holes 201. Several grooves are provided on the spikes 601 so that when the relative distance between the water absorption plate 6 and the grid 2 decreases, the water inside the water absorption plate 6 leaves the grid 2 through the gap between the through holes 201 and the grooves on the spikes 601.

[0041] The water-absorbing plate 6 is slidably connected to the grid 2. The grid 2 is annular and has side plates at both ends. The side plates are circular and have grooves for sliding the water-absorbing plate 6. The grooves are aligned with the radius of the circular side plates. Since the water-absorbing plate 6 is connected to the grid 2 by a spring, the water-absorbing plate 6 is normally separated from the grid 2.

[0042] A support plate is provided between the flow guide shroud 15 and the rotating shaft 3. The support plate is inclined and one side surface of the support plate is in contact with one side surface of the side plate. Since the fixed end of the rotating shaft 3 is connected to the flow guide shroud 15 and the output end of the rotating shaft 3 is connected to the grid 2, the rotating shaft 3 drives the grid 2 to rotate, thereby achieving relative movement between the support plate and the side plate, and thus achieving the effect of the support plate cleaning the dust on the outer wall of the side plate.

[0043] Since the airflow direction inside the flow guide shroud 15 is from the side where the dust removal mechanism is located to the heat dissipation plate, during the heat dissipation of the lamp plate 14, the outside air needs to pass through the dust removal mechanism before entering the interior of the flow guide shroud 15. The grid 2 is set at the inlet end of the flow guide shroud 15, and the outside airflow needs to be filtered by the grid 2 before entering the flow guide shroud 15. The grid 2 is provided with several through holes 201, which are the air inlets of the grid 2. The inner wall size of the through hole 201 matches the outer wall size of the protrusion 601. The water absorption plate 6 is normally separated from the grid 2. When the water absorption plate 6 is subjected to external force, the water absorption plate 6 and the grid 2 engage, and the protrusion 601 enters the through hole 201, pushing out the dust and impurities confined to one side of the grid 2. Since the outer wall of the grid 2 is equipped with a scraper 4, and with the cooperation of the rotating shaft 3, the grid 2 is rotated, and the scraper 4 cleans up the pushed-out dust and impurities.

[0044] During the rotation of the grid 2 driven by the rotating shaft 3, the side plates of the grid 2 and the support plate rotate relative to each other. The support plate cleans the isolation net on the side plate. The isolation net is circular, and the rotating shaft 3 passes through the middle of the circular ring. The outer diameter of the isolation net is smaller than the circumference diameter of the water absorption plate 6.

[0045] The output end of the rotating shaft 3 is connected to the grid 2. Since there are support plates on both sides of the grid 2, the fixed end of the rotating shaft 3 is connected to one of the support plates. A through column is connected to the middle of the limiting plate 5. The through column connects the limiting plate 5 to the support plate on the other side through the through side plate. This ensures that the limiting plate 5 is always in a fixed state relative to the air guide plate 15 during the rotation of the grid 2. This means that the angle between the air guide shroud 15 and the limiting plate 5 is relatively fixed. The limiting plate 5 is fan-shaped and is close to the side where the fan 1 is located. Due to the structure of the outer surface of the limiting plate 5, the distance between each area on the outer wall of the limiting plate 5 and the rotating shaft 3 is not the same. The straight distance between the two ends of the limiting plate 5 and the rotating shaft 3 is greater than the straight distance between the middle of the limiting plate 5 and the rotating shaft 3. The two ends of the limiting plate 5 and the middle area of ​​the limiting plate 5 are connected by a curve.

[0046] Since the straight-line distance between the two ends of the limiting plate 5 and the rotating shaft 3 is greater than the straight-line distance between the middle of the limiting plate 5 and the rotating shaft 3, the water-absorbing plate 6 is distributed in a ring around the rotating shaft 3 on the inner side of the grid 2. When the water-absorbing plate 6 moves to the middle area of ​​the limiting plate 5, the outer wall of the flexible water-absorbing material of the water-absorbing plate 6 is attached to the inner wall of the grid 2 under the action of the limiting plate 5, so that the airflow entering the air guide plate 15 needs to pass through the flexible water-absorbing material and the grid 2 in sequence. During the airflow passing through the flexible water-absorbing material, the airflow dehumidification effect is achieved.

[0047] When the absorbent plate 6 moves to contact the two ends of the limiting plate 5, the inner wall of the grid 2 is in contact with the outer wall of the absorbent plate 6, and the flexible absorbent material is squeezed by the grid 2 and the absorbent plate 6. At this time, the flexible absorbent material inside the absorbent plate 6 is in a squeezed state, and the protrusions 601 on the outer wall of the absorbent plate 6 extend out from the flexible absorbent material and penetrate into the through hole 201, pushing out the dust and impurities inside the through hole 201. When the flexible absorbent material inside the absorbent plate 6 is being squeezed, the water inside the flexible absorbent material is squeezed out. Under the pressure of the absorbent plate 6, the water inside the absorbent plate 6 leaves the grid 2 through the gap between the through hole 201 and the groove on the protrusion 601. The water that leaves comes into contact with the dust and impurities on the outside of the grid 2, achieving the effect of dust reduction.

[0048] When the water-absorbing plate 6 is not in contact with the limiting plate 5, the water-absorbing plate 6, under the action of the spring, causes the flexible water-absorbing material on one side of the water-absorbing plate 6 to separate from the grid 2, and the outside air directly enters the inside of the grid 2 through the through hole 201.

[0049] The water-absorbing plate 6, which comes into contact with the limiting plate 5 inside the grid 2, is separated from the inner wall of the grid 2 under the action of the spring, so that the external airflow does not need to pass through the water-absorbing plate 6 and can directly enter the interior of the grid 2.

[0050] The micro-pattern is used to weaken the vertical dark stripes between each pixel of ADB, so that the optical uniformity transition is consistent. The shape of the micro-pattern is a regular quadrilateral, which ensures the diffusion angle of each pixel of ADB, so that the vertical stripes between each pixel of ADB are uniformly transitioned.

[0051] The incident surface of lens 11 consists of three continuous curved surfaces. The middle curved surface assists in receiving the ADB light pattern, while the curved surfaces on both sides assist in receiving the auxiliary high beam light pattern. The area of ​​the middle curved surface is larger than that of the curved surfaces on both sides.

[0052] The light shield 12 has a toothed structure to block stray light generated during ADB operation. The light shield 12 has two vertical walls in the middle to separate the auxiliary high beam unit and the ADB unit and prevent internal light leakage. The two sides of the light shield 12 have flanged structures to block the light pattern below the auxiliary high beam, so that the high beam light pattern and the ADB light pattern can be better superimposed. The vertical walls of the light shield 12 have equilateral triangle structures with an included angle of 87° and a height of 2.2mm. The equilateral triangle structure is used to weaken stray light. The light shield 12 has two structures that block the auxiliary high beam light pattern. One side is an arc structure and the other side is a rectangular structure to filter the light pattern below the auxiliary high beam.

[0053] The ADB concentrator 7 has a wave-like structure on one side surface, which is used to smoothly transition the outer edge of the ADB light pattern. The lamp panel 14 has three light-emitting units: auxiliary high beam units on both sides and the ADB light-emitting unit in the middle. The ADB light-emitting unit on the lamp panel 14 has 13 LEDs arranged in a straight line. Each LED has an individual duty cycle current to control, and each LED can control its current independently. The two outermost LEDs are connected in series and controlled through a channel. Connecting the two outermost LEDs in series ensures that their duty cycle currents are consistent. By controlling the two outermost LEDs simultaneously, the outer angle of the ADB light pattern is wider, and the transition between dark and bright areas is more uniform. The auxiliary high beam A light-emitting unit is located to the upper left of the ADB light-emitting unit, and the auxiliary high beam B light-emitting unit is located to the lower right of the ADB light-emitting unit. The lamp panel is at a 26° angle to the vehicle mounting direction, further improving optical efficiency.
