Description

Technical Field

[0001] The present invention relates to the technical field of LED vehicle lamps, and in particular to a control method and device for LED vehicle lamps. Background Art

[0002] Traditional headlight designs can only provide fixed lighting ranges and angles. This means that no matter whether the vehicle is driving at high speed, turning at low speed, or facing complex and changing road conditions, the lighting effect of the headlights remains unchanged. However, in actual driving, the driving state and road conditions of the vehicle are ever-changing. Fixed lighting modes cannot meet these changing needs, and sometimes even cause unclear vision or blind spots, increasing driving risks.

[0003] For example, when a vehicle is driving on a curve, traditional headlights cannot fully illuminate the inside of the curve, making it difficult for the driver to judge the road conditions ahead; while when driving on a highway, the fixed lighting angle may make the road conditions in the distance unclear. In addition, in the face of bad weather such as rain, snow, fog and haze, traditional headlights are even more powerless, and their fixed lighting mode cannot penetrate complex weather conditions and provide drivers with clear and sufficient vision.

[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling an LED vehicle lamp, the method comprising the following steps:

[0053] Step 1, receiving a headlight control signal through a first circuit board, and parsing to determine an operation type, including a steering operation, a license plate light operation, or a dynamic headlight adjustment operation;

[0054] Step 2, according to the analyzed operation type, sending a control instruction to the second circuit board or the third circuit board through the first circuit board to execute activation, flashing, constant lighting, or shutting down of the turn signal light body or lighting or extinguishing of the license plate light;

[0055] Step 3: if the operation type is a dynamic headlight adjustment operation, then obtaining vehicle driving information according to the headlight control signal, including vehicle speed, vehicle position, and steering wheel control information;

[0056] Step 4, determining the target map data according to the vehicle's driving information, and calculating the deflection data of the headlights, including the deflection angle and the deflection direction;

[0057] Step 5: Send the deflection data to the headlight control system to adjust the angle and direction of the headlight.

[0058] In the embodiment of the present invention, the control method can receive and analyze multiple types of headlight control signals, thereby achieving accurate control of different types of headlights such as turn signals and license plate lights. This flexibility enables the headlight system to respond quickly and accurately according to different driving conditions and needs. Through dynamic headlight adjustment operations, the headlights can adjust the lighting angle and direction in real time according to vehicle speed, vehicle position, and steering wheel control information. This can not only improve driving visibility at night or in bad weather conditions, but also effectively reduce glare interference to other road users, thereby improving driving safety.

[0059] By precisely controlling the on / off and brightness adjustment of the lights, this control method helps reduce energy consumption and unnecessary light pollution, thereby achieving a more energy-saving and environmentally friendly driving style. According to the actual needs and driving habits of the user, the light control system can automatically make personalized adjustments to provide a more comfortable and convenient lighting experience. By real-time monitoring of the working status of the lights and the control signals received, it helps to promptly detect and handle potential faults or abnormalities, thereby ensuring the stable operation of the light system.

[0060] In a preferred embodiment of the present invention, the above step 1, receiving the headlight control signal through the first circuit board and parsing it to determine the operation type, including a steering operation, a license plate light operation or a dynamic headlight adjustment operation, may include:

[0061] Step 11, the first circuit board monitors the headlight control signal of the vehicle control system;

[0062] Step 12, when the first circuit board receives the vehicle light control signal, the controller on the board parses the control signal, and the parsing process includes identifying the format of the signal and extracting key information, including the operation type, brightness level, and duration;

[0063] Step 13: Based on the parsed information, the first circuit board determines the type of operation to be performed, including a steering operation, a license plate light operation, or a dynamic vehicle light adjustment operation.

[0064] In an embodiment of the present invention, the first circuit board continuously monitors the headlight control signal of the vehicle control system. Once the first circuit board receives the headlight control signal, the onboard controller immediately begins to parse the signals. The parsing process involves identifying the specific format of the signal, including a specific data header, data length, check digit, etc. The controller extracts key information from the signal, such as the type of operation (turning, license plate light on / off, dynamic headlight adjustment, etc.), brightness level (such as the brightness of the headlight), duration (such as flashing frequency or duration), etc. Based on the parsed key information, the first circuit board determines the specific type of operation to be performed. For example, if the parsed operation type is a turning operation, the circuit board will prepare to send a control instruction to activate the turn signal; if it is a dynamic headlight adjustment operation, the data related to the vehicle's driving status will be further processed to calculate the deflection angle and direction of the headlight.

[0065] By continuously monitoring and instantly analyzing the headlight control signals, the system can achieve real-time response to headlight operations, ensuring that the headlight status is consistent with the driver's intention, thereby improving driving safety and comfort.

[0066] The precise signal analysis mechanism can ensure that the headlight control instructions are accurately extracted from the complex vehicle communication environment, avoiding the possibility of misoperation or delayed operation, thereby improving the accuracy of the headlight control system.

[0067] According to different operation types, the system can intelligently adjust the status of the lights, such as automatically adjusting the brightness, flashing frequency or deflection angle, to adapt to different driving environments and needs. By continuously monitoring and analyzing the control signal, the system can also monitor the working status of the light control system in real time, promptly detect and handle potential faults or anomalies, and improve the stability and reliability of the system.

[0068] In a preferred embodiment of the present invention, the above step 2, according to the analyzed operation type, sends a control instruction to the second circuit board or the third circuit board through the first circuit board to execute the activation, flashing, constant lighting, or shutting down of the turn signal light body or the lighting or extinguishing of the license plate light, which may include:

[0069] Step 23, according to the analyzed operation type, the controller on the first circuit board generates a corresponding control instruction;

[0070] Step 24, the first circuit board sends the encoded control instruction to the second circuit board or the third circuit board through the lead hole;

[0071] Step 25, the second circuit board or the third circuit board receives the control instruction of the first circuit board, and performs decoding and verification;

[0072] Step 26, according to the received control instruction, the second circuit board or the third circuit board drives the corresponding LED lamp beads to perform specified operations to activate, flash, keep on, turn off the turn signal, or turn on or off the license plate light.

[0073] In an embodiment of the present invention, once the first circuit board parses the operation type in the vehicle light control signal, the controller thereon generates corresponding control instructions according to preset logical rules. These control instructions are specific to different operations (such as turning, license plate light control, etc.) and contain information about brightness, duration or other parameters. The generated control instructions are then encoded by the first circuit board to ensure data integrity and security during transmission. The encoded instructions are sent to the second circuit board or the third circuit board through a physical connection (such as a lead hole). The second circuit board or the third circuit board is responsible for receiving the control instructions from the first circuit board. After receiving the instructions, they will perform a decoding operation, restore the encoded instructions to the original control information, and verify to ensure the integrity and accuracy of the instructions. Once the instructions are successfully decoded and verified, the second circuit board or the third circuit board will drive the corresponding LED lamp beads to perform specific operations according to the content of the instructions. For example, if the instruction is to activate the turn signal, the corresponding LED lamp beads will be lit and work in a preset mode (such as flashing); if it is a shutdown instruction, the LED lamp beads will go out.

[0074] By distributing the control logic across different circuit boards, the system becomes more modular, which helps isolate faults and improves overall reliability. If a problem occurs on one circuit board, the functions of other circuit boards may not be affected, reducing the risk of a complete system failure. By optimizing the generation, encoding, sending, and receiving processes of instructions, the system is able to achieve efficient instruction transmission, ensuring that the status of the lights can respond quickly and accurately to the driver's operation. This design allows the system to easily adapt to different lighting configurations and control requirements. For example, by adding more circuit boards or modifying the control logic, the system can support more lighting functions or more complex control scenarios. By verifying the integrity and accuracy of the received control instructions, the system can resist potential interference or malicious attacks, thereby ensuring the security of lighting control.

[0075] In a preferred embodiment of the present invention, after executing the control instruction, the working status of the steering assembly, the license plate light and the vehicle light control system is monitored through the first circuit board;

[0076] If during the monitoring process, the first circuit board detects that the working state of the steering component, license plate light or headlight control system is abnormal, an alarm signal will be sent immediately to indicate a system failure.

[0077] In the embodiment of the present invention, after executing the control instruction, the first circuit board is not only responsible for sending the instruction, but also undertakes the task of monitoring the working status of the steering component, the license plate light and the headlight control system. It collects the working status information of these components and systems in real time through various sensors or feedback mechanisms. The first circuit board processes and analyzes the collected data, and detects whether there is any abnormality by comparing it with the preset normal working parameter range. Abnormal conditions include response delay of the steering component, failure of the license plate light to light up or go out normally, abnormal voltage of the headlight control system, etc. Once any abnormality is detected, the first circuit board will immediately generate an alarm signal. This alarm signal is a specific electronic signal used to trigger the fault indicator light on the vehicle dashboard, or an error code sent to the vehicle main control system for further processing and recording.

[0078] Through real-time monitoring and anomaly detection mechanisms, the system can detect faults in steering components, license plate lights or headlight control systems at the first time, preventing small problems from turning into major faults, thereby improving driving safety. Timely alarm signals can let drivers or maintenance personnel know potential problems as early as possible, so as to carry out preventive maintenance and extend the service life of the headlight system. Through continuous monitoring and feedback, it can ensure that each component of the headlight system is always in the best working condition, improving the reliability of the entire system. The normal operation of the headlight system is crucial to driving safety at night or in bad weather. Timely fault alarms can help drivers avoid safety risks caused by headlight system failures at critical moments.

[0079] In a preferred embodiment of the present invention, in step 3, if the operation type is a dynamic headlight adjustment operation, obtaining vehicle driving information according to the headlight control signal, including vehicle speed, vehicle position, and steering wheel control information, may include:

[0080] In an embodiment of the present invention, the first circuit board continuously monitors the headlight control signal issued by the vehicle control system. When the operation type is identified as a dynamic headlight adjustment operation, the first circuit board is ready to receive and process data related to the vehicle's driving status. The vehicle speed sensor is installed in the drive axle housing of the vehicle and displays the vehicle speed by generating an alternating current signal. These signals are converted into current amplitudes, indicating the specific vehicle speed, and transmitted to the first circuit board. The vehicle position is obtained through a GPS receiver. The GPS receiver receives signals from satellites and determines the three-dimensional position (longitude, latitude and altitude) of the vehicle by calculating the signal propagation time. The calculation formula for the signal propagation time is: ; represents the signal propagation time; Indicates the time when the satellite sends the signal; Indicates the time when the receiver receives the signal; the steering wheel's rotation angle and speed are transmitted to the steering sensor through a series of mechanical connection components (such as steering shaft, steering gear). The steering sensor converts these mechanical movements into electrical signals and transmits them to the first circuit board, thereby reflecting the driver's steering intention and direction. The first circuit board receives and integrates information from different sensors, including vehicle speed, vehicle position and steering wheel control information. Based on this information, the controller on the first circuit board calculates parameters such as the angle and brightness of the headlights. The calculation formula for the headlight brightness parameters is: ;in, Indicates the brightness parameter of the headlight; Indicates the adjustment coefficient of vehicle speed to brightness; Indicates vehicle speed; Indicates the nonlinear adjustment coefficient of the steering angle to the brightness; Indicates the basic brightness value; Indicates the steering angle. The controller generates corresponding control instructions and prepares to send them to the second circuit board or the third circuit board responsible for performing the lamp adjustment. The second circuit board or the third circuit board receives the control instructions from the first circuit board. According to the instructions, these circuit boards drive the lamp actuator (such as a stepper motor or a DC actuator) to make adjustments. The lamp dynamically adjusts its illumination direction, range and brightness according to the calculated parameters to adapt to the current driving conditions and the driver's intentions.

[0081] In a preferred embodiment of the present invention, the calculation formula for the deflection angle of the headlight is: ;

[0082] in, Indicates the deflection angle of the headlight; , , , represents the adjustment factor; Indicates vehicle speed; An exponential parameter representing vehicle speed; represents the base of natural logarithms; Indicates the steering wheel angle; Indicates the reference value of the steering wheel angle; Indicates driving trajectory deviation; , An exponential parameter representing the deviation of the driving trajectory; Represents a constant term.

[0083] In the embodiment of the present invention, the vehicle speed It is one of the important factors affecting the deflection angle of the headlights. When the vehicle speed increases, the headlights need to adjust their lighting range faster to adapt to the road changes, so the deflection angle will increase accordingly. Adjustment coefficient and exponential parameters Together they determine the specific extent to which vehicle speed affects the deflection angle.

[0084] Steering wheel angle It reflects the driver's steering intention. When the driver turns the steering wheel, the headlights should adjust their lighting direction accordingly to illuminate the upcoming curve or turning area in advance. Adjustment coefficient , , and the reference value of the steering wheel angle Together they determine the effect of the steering wheel angle on the deflection angle. Driving trajectory deviation Indicates the difference between the vehicle's current trajectory and the expected trajectory. When the vehicle deviates from the expected trajectory, the headlights need to adjust their lighting direction to provide better visibility and safety. Adjustment factor , index parameters and The influence of the driving trajectory deviation on the deflection angle is jointly controlled. is used to determine the direction of deflection (positive or negative), and Used to determine the deflection angle. Used to adjust the basic deflection angle to ensure that the lights can maintain the appropriate lighting direction under different driving conditions.

[0085] The formula can calculate the deflection angle of the headlights in real time based on multiple dynamic parameters such as vehicle speed, steering wheel angle, and driving trajectory deviation. This allows the headlights to flexibly adjust the lighting direction under different driving conditions and better adapt to road changes and driving needs. By accurately calculating the deflection angle, the headlights can more accurately illuminate the road ahead, especially when turning or turning, and can illuminate the area the driver is about to drive in advance, thereby improving driving safety at night or in bad weather. Adjustment coefficient , , , and exponential parameters , , It can be adjusted according to different vehicle models and driving habits. This flexibility enables the lighting system to better meet the needs and preferences of different users. By precisely controlling the deflection angle of the lights, it can reduce glare interference to drivers of oncoming vehicles and improve the overall safety and comfort of road users.

[0086] It can be integrated with other intelligent systems of the vehicle (such as navigation, sensors, etc.) to achieve a higher level of automation and intelligent control. For example, in the autonomous driving mode, the lighting system can automatically adjust the lighting direction according to the vehicle's autonomous navigation path.

[0087] In a preferred embodiment of the present invention, the calculation formula for the deflection direction of the headlight is: ;

[0088] in, Indicates the deflection direction of the headlight; Indicates the preset angle value; Indicates the steering wheel angle The linear adjustment coefficient of represents the nonlinear effect of steering wheel angle; Indicates the maximum possible steering wheel angle; Indicates the vehicle speed adjustment coefficient; Indicates the driving trajectory deviation adjustment coefficient.

[0089] In an embodiment of the present invention, It is a preset angle value, which represents the default deflection direction of the headlight without any dynamic input. This value is usually set according to vehicle design and road lighting requirements.

[0090] Steering wheel angle It has a direct impact on the deflection direction of the headlights. is the linear adjustment coefficient of the steering wheel angle, which determines the direct proportional effect of the steering angle on the deflection direction; and It reflects the nonlinear effect of the steering wheel angle and is used to more finely adjust the light deflection direction, especially at large turning angles. The maximum possible steering wheel angle, used to standardize the actual steering angle to keep the calculation consistent across different vehicle models and driving conditions. It also affects the deflection direction of the headlights. Considering this effect, It is the speed adjustment coefficient, which can smoothly handle the change of vehicle speed and avoid excessive deflection at high speed. Indicates the degree of deviation between the vehicle's current driving path and the expected path. Used to adjust the deflection direction of the headlight according to the trajectory deviation. is the driving trajectory deviation adjustment coefficient, and It is ensured that the deflection direction is consistent with the direction of trajectory deviation.

[0091] Steering wheel angle , vehicle speed and driving trajectory deviation Multiple factors, such as the light, enable the headlights to be flexibly and accurately deflected according to driving conditions, improving driving safety and visibility at night or in bad weather. By combining the adjustment coefficients, the system can smoothly and continuously adjust the deflection direction of the headlights according to the real-time changes in the steering wheel angle, enhancing the driver's perception and control of the vehicle's direction of travel. It shows that the system can automatically adjust the deflection angle of the headlights according to the vehicle speed to ensure that the appropriate lighting range can be provided at different speeds, avoiding glare and ensuring sufficient vision. The deviation of the driving trajectory is taken into account, so that the headlights can respond in time when the vehicle deviates from the normal trajectory, and adjust the deflection direction to remind the driver or help correct the driving direction, thereby increasing the stability and safety of driving.

[0092] In a preferred embodiment of the present invention, the above step 5, sending the deflection data to the headlight control system to adjust the angle and direction of the headlight, may include:

[0093] Step 51, sending the deflection data to the vehicle light control system via a communication connection;

[0094] Step 52, the vehicle light control system receives the deflection data of the first circuit board through the communication interface, and decodes and processes it to extract the deflection angle and direction adjustment amount;

[0095] Step 53, the vehicle light control system generates a corresponding control signal according to the deflection angle and the direction adjustment amount;

[0096] Step 54, the control signal is sent to the mechanical structure of the headlight, including the servo motor and the stepper motor actuator;

[0097] Step 55: The actuator adjusts the angle and direction of the vehicle light according to the received control signal.

[0098] In an embodiment of the present invention, the deflection data, including the deflection angle and the direction adjustment amount, is first sent from the processing unit (such as the first circuit board) to the headlight control system through a communication connection (such as a CAN bus). The communication connection ensures the fast and accurate transmission of data, and provides a guarantee for the real-time adjustment of the headlight. The headlight control system receives the deflection data from the first circuit board through a dedicated communication interface. The received data is decoded and processed to extract the specific deflection angle and direction adjustment amount, which are the key parameters for the headlight adjustment. According to the decoded deflection angle and direction adjustment amount, the internal algorithm of the headlight control system generates a corresponding control signal. The control signal is a direct instruction to adjust the angle and direction of the headlight, which must be accurate. The generated control signal is then sent to the mechanical structure of the headlight, including actuators such as servo motors and stepper motors. These actuators are the power source for the adjustment of the headlights, and are responsible for accurately adjusting the angle and direction of the headlights according to the control signal. After receiving the control signal, the actuator starts working and makes subtle and precise angle and direction adjustments to the headlights. After the adjustment is completed, the headlights will illuminate the road at a new angle and direction, providing better lighting effects and safety.

[0099] Through efficient communication connections, the headlight control system can receive and process deflection data in real time to ensure the timeliness and accuracy of headlight adjustment. Using advanced decoding algorithms and control strategies, the headlight control system can generate precise control signals to achieve fine adjustment of the angle and direction of the headlights. By adjusting the angle and direction of the headlights, you can better adapt to different road conditions and driving needs, and improve driving safety at night or in bad weather.

[0100] like Figure 2 As shown, an embodiment of the present invention further provides a control device 20 for an LED vehicle lamp, comprising:

[0101] The acquisition module 21 is used to receive the vehicle light control signal through the first circuit board, and analyze it to determine the operation type, including a steering operation, a license plate light operation or a dynamic vehicle light adjustment operation; according to the analyzed operation type, send a control instruction to the second circuit board or the third circuit board through the first circuit board to execute the activation, flashing, constant lighting, or shutting down of the turn signal body or the lighting or extinguishing of the license plate light;

[0102] The processing module 22 is used to obtain the vehicle driving information, including the vehicle speed, vehicle position, and steering wheel control information, according to the headlight control signal if the operation type is a dynamic headlight adjustment operation; determine the target map data according to the vehicle driving information, and calculate the deflection data of the headlights, including the deflection angle and deflection direction; and send the deflection data to the headlight control system to adjust the angle and direction of the headlights.

[0103] like Figures 3 to 7 As shown, an embodiment of the present invention provides an LED vehicle lamp, comprising:

[0104] Headlight body;

[0105] Steering components, installed at both ends of the lamp body;

[0106] A license plate light 3, arranged on the vehicle light body;

[0107] The first circuit board 4 is arranged inside the vehicle lamp body and is used to drive and control the steering assembly and the license plate light 3 .

[0108] In the embodiment of the present invention, when the vehicle light system is activated, the first circuit board 4 starts to work and performs self-checking and initialization procedures. The vehicle light body serves as a supporting structure to ensure that all components are firmly installed, and provides necessary heat dissipation, waterproof and dustproof protection to create a stable working environment for the internal electronic components. The first circuit board 4 receives instructions through the vehicle control system, such as turning on the lights, steering, etc., or instructions automatically issued by the automatic sensing system according to the ambient light. The processor on the first circuit board 4 processes the received signal and determines the operation to be performed, such as whether the steering component or the license plate light 3 needs to be lit.

[0109] When the vehicle needs to turn, the driver will operate the steering wheel and trigger the turn signal. After receiving this signal, the first circuit board 4 will control the steering components installed at both ends of the lamp body to light up. The high-brightness LED lights in the steering components begin to flash to indicate the direction of the vehicle's travel and improve driving safety. When the ambient light is insufficient or driving at night, the first circuit board 4 will automatically control the license plate light 3 to light up according to the input of the light sensor or the preset time conditions. The license plate light 3 illuminates the license plate to ensure that the license plate information is clearly visible at night or in an environment with insufficient light to meet regulatory requirements. During the operation of the lamp system, the first circuit board 4 continuously monitors the working status of each component and makes adjustments as needed, such as adjusting the brightness or flashing frequency of the LED. When the lamp system is manually turned off, the first circuit board 4 will send a command to turn off all active lamp components and put the system into a dormant state, waiting for the next activation.

[0110] The headlight design improves driving safety through precise turn indication and clear license plate lighting. The quick response and high-brightness lighting of the steering assembly can accurately and promptly inform other road users of the vehicle's driving intentions, reducing traffic accidents caused by misunderstandings or unclear vision. The design of the license plate light 3 ensures that the license plate is clearly visible at all times, which not only helps the supervision of traffic management departments, but also complies with the requirements of traffic regulations. The intelligent headlight control system can automatically adjust the lighting mode according to the driving environment and needs, providing the driver with a more comfortable and safe driving environment. At the same time, the simple and efficient headlight design also enhances the appearance and technological sense of the entire vehicle.

[0111] like Figures 3 to 7 As shown, the vehicle lamp body comprises:

[0112] The housing 1 is provided with a groove 5 of the same size as the license plate light 3 for fixing the license plate light 3 .

[0113] In the embodiment of the present invention, a groove 5 of the same size as the license plate light 3 is specially designed on the housing 1. The groove 5 is used to fix the license plate light 3 to ensure that it is stably and accurately installed at a predetermined position. When installing the license plate light 3, it is placed in the groove 5, and the housing 1 fixes the license plate light 3, so that the license plate light 3 can work stably and will not move or fall off due to the vibration of the vehicle or the bumps during driving.

[0114] By providing a groove 5 of the same size as the license plate light 3 on the housing 1, the stability and accuracy of the license plate light 3 can be ensured. This design effectively prevents the license plate light 3 from shifting or falling off due to vibration during the driving of the vehicle, thereby improving the overall structural stability of the vehicle light system. The design of the groove 5 makes the installation of the license plate light 3 simpler and faster. The size of the groove 5 matches that of the license plate light 3, so that the license plate light 3 can be perfectly integrated into the design of the vehicle light body, improving the overall aesthetics of the vehicle light. The stable installation of the license plate light 3 can ensure that its lighting effect is not affected by vibration during driving, thereby keeping the license plate clearly visible, meeting the requirements of traffic regulations, and also improving driving safety at night or in bad weather conditions.

[0115] like Figures 3 to 7 As shown, the steering assembly includes:

[0116] Two lamp holders 2 are provided and connected to both ends of the housing 1;

[0117] A turn signal lamp body 6 is mounted on the lamp holder 2;

[0118] The second circuit board 7 is fixed to the bottom of the lamp holder 2 and is used to control the on and off of the turn signal lamp body 6 .

[0119] In the embodiment of the present invention, the steering assembly is an important part of the vehicle lamp system, including a lamp holder 2, a steering lamp body 6 and a second circuit board 7. Two lamp holders 2 are provided, which are respectively connected to the two ends of the housing 1, providing a stable installation foundation for the steering lamp body 6. The steering lamp body 6 is installed on the lamp holder 2, and is responsible for sending a bright turn signal when the vehicle turns. The second circuit board 7 is fixed to the bottom of the lamp holder 2 to control the on and off of the steering lamp body 6. When the vehicle needs to turn, the vehicle's control system will send a signal to the second circuit board 7. After receiving the signal, the second circuit board 7 will process the instruction and control the steering lamp body 6 to light up or go out according to the instruction. In this way, the steering lamp body 6 can send a bright signal in time when the vehicle turns, alerting other road users.

[0120] The turn signal lamp body 6 is firmly connected to both ends of the housing 1 through the lamp holder 2, ensuring the structural stability of the steering assembly. Even if the vehicle encounters bumps or vibrations during driving, the turn signal lamp body 6 can remain stable and will not affect the use effect due to movement or falling off. The second circuit board 7 can quickly receive and process the signal of the vehicle control system to ensure that the turn signal lamp body 6 can light up immediately when the vehicle needs to turn and send a turn signal in time. Through the precise control of the second circuit board 7, the turn signal lamp body 6 can be easily turned on and off. If the turn signal lamp body 6 or the second circuit board 7 fails, it can be repaired or replaced separately without large-scale disassembly and repair of the entire vehicle light system.

[0121] like Figures 3 to 7 As shown, a third circuit board 9 is provided inside the license plate light 3 .

[0122] In the embodiment of the present invention, the third circuit board 9 disposed inside the license plate light 3 is used to control the lighting function of the license plate light. When the vehicle light system is activated or when the ambient light is dark enough to require the license plate light to illuminate, the third circuit board 9 will receive a signal from the control system of the first circuit board 4. After receiving the signal, the third circuit board 9 will process the instruction and control the LED inside the license plate light 3 to light up, thereby illuminating the license plate and ensuring that the license plate is clearly visible at night or in an environment with insufficient light.

[0123] The third circuit board 9 can precisely control the brightness of the license plate light to avoid unnecessary energy consumption. When full brightness lighting is not required, the brightness can be reduced to save energy while still keeping the license plate clearly visible. Through precise circuit control, the third circuit board 9 can prevent the license plate light from overheating due to long-term high brightness operation. Ensuring that the license plate is clearly visible at all times is an important requirement for traffic safety. The precise control of the third circuit board 9 helps to maintain the continuous visibility of the license plate, thereby improving driving safety. Since a special circuit board is provided inside the license plate light 3, once a fault occurs, maintenance personnel can more easily locate the problem and repair it, improving maintenance efficiency.

[0124] like Figures 3 to 7 As shown, a lead hole 8 is provided inside the vehicle lamp body.

[0125] In the embodiment of the present invention, the lead hole 8 provided inside the vehicle lamp body is used to organize and guide the wires and connecting wires inside the vehicle lamp system. During the assembly process of the vehicle lamp system, various wires need to be arranged reasonably to ensure smooth transmission of current and correct connection between various electronic components. The lead hole 8 provides an orderly channel so that the wires can pass from one part of the vehicle lamp body to another part without causing confusion or mutual interference.

[0126] The lead hole 8 helps to organize and manage the wires inside the headlight system, preventing the wires from getting tangled or misplaced, thereby ensuring the stability and reliability of current transmission. By properly arranging the wires through the lead hole 8, the exposed portion of the wires can be reduced, reducing the safety hazards caused by wire damage or poor contact. When repairing or replacing the headlight assembly, the wires arranged in an orderly manner through the lead hole 8 can be more easily identified and tracked, simplifying the repair process. The orderly layout of wires helps to reduce electromagnetic interference and improve the overall electronic stability of the headlight system. The lead hole 8 makes the interior of the headlight body neater and improves the overall aesthetics of the product.

[0127] During the manufacturing process, an orderly layout of the wires is achieved through the lead holes 8, which can simplify the assembly process and improve production efficiency.

[0128] like Figures 3 to 7 As shown, the first circuit board 4 provides power and control signals to the second circuit board 7 , the third circuit board 9 and the license plate light 3 through the lead hole 8 .

[0129] In the embodiment of the present invention, the first circuit board 4 serves as the core control board of the vehicle light system, and provides necessary power and control signals to the second circuit board 7, the third circuit board 9 and the license plate light 3 through the lead hole 8 inside the vehicle light body. The lead hole 8 plays a key bridge role, which allows the wires and connecting wires to be safely and orderly transmitted from the first circuit board 4 to other parts of the vehicle light system. When the vehicle light system is started, the first circuit board 4 will send a control signal to the second circuit board 7 through the lead hole 8 to activate or turn off the turn signal body 6 according to the received vehicle control system instructions or preset programs. At the same time, the first circuit board 4 will also send a signal to the third circuit board 9 to control the switch and brightness of the license plate light 3. In addition, the license plate light 3 itself may also receive power supply directly from the first circuit board 4.

[0130] The first circuit board 4 acts as a central controller, and sends instructions to the second circuit board 7 and the third circuit board 9 through the lead hole 8, thereby realizing centralized control and management of the vehicle lighting system and simplifying the system structure. By optimizing power distribution, the first circuit board 4 can ensure that each component obtains sufficient power when needed, while avoiding unnecessary energy consumption. Orderly wiring layout and signal transmission can reduce electromagnetic interference and improve the accuracy and stability of signal transmission. Through direct control signal transmission, it can ensure that the vehicle lighting system responds quickly to the driver's operation and improve driving safety.
