TECHNICAL FIELD

[0001] The utility model relates to the field of vehicle lighting, more specifically, it relates to a vehicle lamp. BACKGROUND

[0002] With the development of automotive electronic technology, the safety and comfort of vehicles are increasingly valued. In the control of automotive headlamps, ADB (Adaptive Driving Beam) technology is used, and the light distribution control device is used to prevent dazzling of oncoming vehicles or pedestrians in the front area of the vehicle, and on the other hand, to improve the visibility of the front area, thereby improving the safety during driving.

[0003] The current adaptive high beam system often only directly converts the high beam and low beam of two-wheeled motor vehicles, ignoring the limited turning high beam field of view of two-wheeled motor vehicles when turning, which can easily cause accidents. The combination of HIAS structure (Horizontal Illumination Adjustment System) and ADB (Adaptive Driving Beam) can further improve the intelligence and safety of the vehicle lamp system. This combined structure can dynamically adjust the distribution and intensity of the light according to the vehicle driving state, environmental lighting conditions, and surrounding traffic conditions, thereby optimizing the lighting effect.

[0035] Embodiment:

[0036] A vehicle lamp, as shown in reference to Figure 1 and Figure 2 includes a high-beam lighting module for generating a first light distribution and a controller for controlling the high-beam lighting module. The high-beam lighting module includes a first lens 1, a first PCB board 2, a radiator 3 and a driver 4. A high-beam light source 5 is provided on the first PCB board 2. The high-beam light source 5 is a number of high-beam LED lamp beads arranged in an array. The driver 4 drives the radiator 3 and the high-beam light source 5 to rotate synchronously to adjust the deflection angle of the first light distribution. It further includes an auxiliary light source 6. The controller is communicatively connected to a sensor. According to the vehicle body attitude feedback by the sensor, the controller controls the rotation of the driver 4. According to the road conditions ahead feedback by the sensor, the controller controls the switching of some high-beam LED lamp beads to adjust the shape of the first light distribution and controls the switching of the auxiliary light source 6.

[0037] Refer to Figure 4 and Figure 5In some embodiments, the auxiliary light source 6 is arranged on the first PCB board 2. When the auxiliary light source 6 is in the lighting state, it plays a complementary light to the high beam light source 5, realizing the high-light mode. When the sensor detects a sharp turn, a wide open road section, or the high beam light source 5 must be dimmed due to rain, the auxiliary light source 6 can be turned on to increase or complement the light.

[0038] For the above embodiment, the lamp bead of the auxiliary light source 6 can be the same as the high beam LED lamp bead. By turning on the auxiliary light source 6, the brightness of the high beam light source 5 is increased.

[0039] In some embodiments, the high beam lighting module includes a heat sink 3, a first lens 1, and a first PCB board 2 fixedly connected with the heat sink, and a driver is in transmission connection with the heat sink 3. The heat sink 3 and the first PCB board 2 rotate relative to the first lens 1.

[0040] In other embodiments, the high beam lighting module includes a heat sink 3, a first PCB board 2 fixedly connected with the heat sink, and a first lens 1. A driver drives the heat sink 3, the first PCB board 2, and the first lens 1 to rotate synchronously.

[0041] Referring to Figure 3 In other embodiments, the high beam lighting module further includes an auxiliary lighting module arranged on both sides of the high beam lighting module. The auxiliary lighting module generates a second light distribution. The auxiliary lighting module includes a second lens 10 and a second PCB board 9. An auxiliary light source 6 is arranged on the second PCB board 9. Compared with the previous technical solution, the present application uses an independent second lens 10 and a second PCB board 9 to cooperate with the auxiliary light source 6 to realize the second light distribution. The auxiliary light source 6 includes a low beam light source 7 and an auxiliary high beam light source 8. The auxiliary light source 6 realizes a dual-light structure. The auxiliary high beam light source 8 plays a complementary light when the high beam light source 5 is turned off. The functional difference between the two light sources is realized according to the arrangement of the second lens 10. The high beam light source 5 includes sensitive area light sources. According to the front condition fed back by the sensor, the controller controls the switching of the corresponding sensitive area light sources. The high beam light source 5 includes an upper light source and a lower light source. According to the undulating condition of the front terrain and the vehicle body posture fed back by the sensor, the controller controls the switching of the upper light source and the lower light source.

[0042] It should be noted that the division of the sensitive area light source and the non-sensitive area light source and the upper light source and the lower light source are concepts set for the convenience of the controller management. In practice, the controller can mark these specific high beam LED lamp beads for corresponding switching.

[0043] For the above embodiment, by adjusting the high beam light source 5, the low beam light source 7, and the auxiliary high beam light source 8, safe lighting and intelligent lighting can be realized in the following scenarios:

[0044] Scenario 1: When a two-wheeled vehicle passes through a sharp or continuous curve at night, the inclination of the vehicle body can cause the traditional light pattern to shift, resulting in insufficient illumination on the inside and possible glare to oncoming vehicles. HIAS: The driver 4 rotates to keep the light pattern level, ensuring uniform illumination on both the inside and outside of the curve. ADB: The high beam light source 5 dynamically adjusts the irradiation range to avoid oncoming vehicles or pedestrians, preventing glare. AHB: The auxiliary high beam light source 8 automatically enhances the brightness of the high beam when there are no oncoming vehicles, expanding the illumination range (e.g., illuminating the exit of the curve). In sharp curves, both glare is avoided and the high beam is enhanced by the auxiliary high beam light source 8, allowing for early detection of obstacles or road abnormalities.

[0045] Scenario 2: Urban cycling often involves frequent interactions with pedestrians, bicycles, and vehicles, sudden lane changes, and sharp turns. HIAS: The driver 4 rotates to keep the light pattern level during turns, avoiding blind spots caused by the inclination of the vehicle body. ADB: Real-time detection of surrounding vehicles and pedestrians causes the high beam light source 5 to automatically shut off sensitive areas (such as the height of a pedestrian's head). AHB: In open road sections, the auxiliary high beam light source 8 (such as at a vehicle-free intersection) temporarily enhances the high beam, improving visual clarity. Dynamically balancing illumination intensity and safety, it avoids complaints or accidents caused by excessively strong high beams.

[0046] Scenario 3: Off-road mountain biking requires dealing with bumpy roads, steep slopes, and sharp turns, and the illumination needs to consider both breadth and intensity. HIAS: When the vehicle body is significantly inclined (such as when passing through steep curves), the light pattern is maintained horizontally to avoid illumination deviation. ADB: According to the terrain undulations, the high beam angle is dynamically adjusted by switching between upper and lower light sources (e.g., lowering the beam height when descending). AHB: In open areas (such as mountain tops), the auxiliary high beam light source 8 enhances the high beam, covering a larger field of view. In complex terrain, it provides stable and flexible lighting support, reducing the risk of accidents caused by poor visibility.

[0047] Scenario 4: In rainy conditions, the road surface reflects strongly, and traditional vehicle lights are prone to glare or insufficient illumination. HIAS: Maintaining the light pattern level avoids light scattering caused by the inclination of the vehicle body. ADB: The high beam light source 5 reduces the intensity of the high beam to reduce the light curtain reflection effect in rain and fog. AHB: The auxiliary high beam light source 8 locally enhances illumination when driving at low speed (such as illuminating the nearby water accumulation area). By dynamically adjusting the light, it reduces the interference of rain and fog while ensuring the illumination needs of key areas.

[0048] The sensors include a camera and a gyroscope. The camera feeds back road condition information, and the gyroscope feeds back the vehicle body posture. Road condition information includes both narrow road conditions and broad road conditions, including roads, vehicles, pedestrians, and obstacles, weather, and other driving reference information.

[0049] The driver 4 is one of a direct current motor, an alternating current motor, a stepper motor, a servo motor, and a brushless motor.

[0050] The application has a HIAS system, the HIAS system comprising a driver 4 driving a heat sink 3 and the driver 4 and a relatively static lens, the deflection angle of the first light distribution being adjusted by rotating the heat sink 3 and the driver 4. In order to make the heat sink 3 and the driver 4 rotate without distortion of the first light distribution finally generated, the first lens 1 is set as a rotary body, and the rotary axis thereof coincides with the rotation axis of the heat sink 3 and the driver 4.

[0051] The application also has an ADB system, the high beam light source 5 being a plurality of arrayed high beam LED lamp beads, the controller being capable of independently adjusting the on-off of the high beam LED lamp beads as required, thereby realizing adjustment of the shape of the first light distribution.

[0052] The application also has an AHB, the auxiliary light source 6 being set, switched as required, and further illuminating in the case of insufficient illumination light distribution in the plane of the driving direction of the two-wheeled vehicle.

[0053] By combining the above three, the lighting safety and intelligent level of the two-wheeled vehicle (such as a motorcycle, an electric bicycle) in a complex scene can be significantly improved.

[0054] The above-described embodiments are only preferred schemes of the application, and do not limit the application in any form, and there are other variants and modifications without exceeding the technical scheme recorded in the claims.
