Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Currently, dual-beam module solutions with anti-glare function on the market typically use a shared outer lens for both low beam and ADB, and then each low beam and ADB has its own corresponding inner lens. This results in a complex structure with many parts, leading to high costs and large deviations.

[0022] The following is for reference. Figures 1-6 A lens assembly according to an embodiment of the present invention is described.

[0023] According to the present invention, the lens assembly 1 includes a first lens 11, a first light-emitting element 12, a second lens 13, and a second light-emitting element 14. The first lens 11 has a first light-inlet end 111 and a first light-outlet end 112 formed at its two ends, respectively. The first light-emitting element 12 is disposed at one end of the first lens 11 and is adapted to emit light to the first light-inlet end 111. The second lens 13 is provided with a second light-inlet end 1301 and a third light-inlet end 1302, and the third light-inlet end 1302 is correspondingly disposed to the first light-outlet end 112. The second light-emitting element 14 corresponds to the second light-inlet end 1301 and is adapted to emit light to the second light-inlet end 1301.

[0024] The lens assembly 1 according to this utility model includes a first lens 11 and a second lens 13. The first lens 11 has a first light-inlet end 111 and a first light-outlet end 112 formed at its two ends, as shown below. Figure 1As shown, a first light-emitting element 12 is provided on one side of the first light-inlet end 111. The first light-emitting element 12 can be simply understood as an ADB high beam source in the background art. The high beam light emitted by the first light-emitting element 12 can directly enter the first lens 11 through the first light-inlet end 111, and after being converged and refracted by the first lens 11, it is emitted from the first light-emitting end 112. The second lens 13 is arranged at a distance from the first lens 11. A second light-inlet end 1301 and a third light-inlet end 1302 are formed on the second lens 13, which are spaced apart from each other. A second light-emitting element 14 is provided on one side of the second light-inlet end 1301. The light-emitting element 14 can be understood as a low beam light source in the background art. The low beam light emitted by the second light-emitting element 14 can enter the second lens 13 through the second light-inlet end 1301. The third light-inlet end 1302 corresponds to the first light-outlet end 112. Therefore, the high beam light emitted from the first light-outlet end 112 can enter the third light-inlet end 1302 of the second lens 13. That is, the light emitted by the first light-emitting element 12 (ADB high beam light source) and the second light-emitting element 14 (low beam light source) can both enter the second lens 13 and be transmitted to the outside through the second lens 13 to realize the ADB high beam and low beam functions of the vehicle headlight.

[0025] The second lens 13, by having a second light-inlet end 1301 corresponding to the second light-emitting element 14 and a third light-inlet end 1302 corresponding to the first light-emitting end 112, can respectively introduce ADB high beam and low beam. It integrates the functions of a traditional low beam inner lens, low beam outer lens, and ADB high beam outer lens, allowing the low beam and ADB high beam to enter the corresponding parts of the second lens 13 through different paths and ultimately illuminate the outside, ensuring that the vehicle headlight can achieve both ADB high beam and low beam functions. The integrated design of the second lens 13, which combines a low beam inner lens, a low beam outer lens, and an ADB high beam outer lens, simplifies the overall structure of the lens assembly 1, reduces the number of parts, lowers costs, and reduces assembly deviations. It ensures high luminous efficiency while achieving good ADB beam pattern and low beam, improving the performance and safety of the vehicle lighting system and providing a more optimized and economical solution for the vehicle lighting system.

[0026] According to one embodiment of the present invention, the second lens 13 includes: a first light guide 131 and a second light guide 132. The first light guide 131 is spaced apart from the first lens 11 and has a second light-entry end 1301 formed at one end. The second light guide 132 is connected to the first light guide 131 and at least partially protrudes from the first light guide 131 to form a third light-entry end 1302 on the side facing the first lens 11.

[0027] like Figure 2As shown, the second lens 13 is provided with a first light guide 131 and a second light guide 132. The first light guide 131 is spaced apart from the first lens 11, and a second light-entry end 1301 is formed at one end of the first light guide 131. The light generated by the second light-emitting element 14 can directly enter the first light guide 131 through the second light-entry end 1301 and be orderly conducted and focused inside the first light guide 131. This reduces the scattering and energy loss of the low beam light during propagation, and allows more low beam light to reach the designated position according to the design requirements, thereby improving the utilization efficiency and illumination intensity of the low beam light.

[0028] The second light guide 132 is connected to the first light guide 131, and at least a portion of the second light guide 132 protrudes from the first light guide 131 in the height direction to form a third light-inlet end 1302 on the side facing the first lens 11. The ADB high beam emitted by the first light-emitting element 12 passes through the first lens 11 and exits from the first light-emitting end 112, and can enter the second light guide 132 at the corresponding position through the third light-inlet end 1302. At the same time, the low beam emitted by the second light-emitting element 14 can directly enter the second light guide 132 after passing through the first light guide 131. That is, both the low beam and the ADB high beam can be transmitted to the outside through the second light guide 132. The design of the combination of the first light guide 131 and the second light guide 132 cleverly realizes the separate transmission and final convergence of the low beam and the ADB high beam, which not only ensures the independence of the two light types, but also maximizes the utilization of light efficiency. The coordinated operation of the first light guide 131 and the second light guide 132 not only optimizes the light path and reduces light attenuation during transmission, but also eliminates the need for additional external lens structures corresponding to the ADB light source and low beam light source in traditional vehicle lights, reducing the number of parts, production costs, and assembly difficulty; it also ensures that the low beam and ADB high beam can illuminate the target area with ideal light pattern and intensity, thereby significantly improving the overall performance and safety of the vehicle lighting system.

[0029] According to one embodiment of the present invention, at least a portion of the wall surface of the first light guide 131 is configured as a total internal reflection surface to guide light from the second light input end 1301 to the second light guide 132. Configuring at least a portion of the wall surface of the first light guide 131 as a total internal reflection surface allows light entering the first light guide 131 from the second light input end 1301 to propagate almost without loss under the action of the total internal reflection surface. In conventional structures, light may lose some energy due to refraction and scattering when propagating on the lens wall surface. The design of the total internal reflection surface effectively reduces this energy loss, allowing more light to reach the second light guide 132, thereby improving the light transmission efficiency of the entire lens assembly 1 and enhancing the illumination brightness.

[0030] According to one embodiment of the present invention, the first light guide 131 includes: a first segment 1311, a second segment 1312 and a third segment 1313. The first segment 1311 extends in the front-back direction, and the rear end of the first segment 1311 forms a second light-inlet end 1301. The second segment 1312 is connected to the first segment 1311, extends towards the front and is inclined in the height direction. The third segment 1313 is connected to the second segment 1312, extends in the horizontal direction and is connected to the second light guide 132.

[0031] like Figure 2 As shown, the first light guide 131 is provided with a first segment 1311, a second segment 1312 and a third segment 1313 connected in sequence. The first segment 1311 extends in the front-back direction, and a second light-inlet end 1301 is formed at the rear end of the first segment 1311. The second light-emitting element 14 is disposed on the rear side of the first segment 1311, which can ensure that the near light emitted by the second light-emitting element 14 can directly enter the first light guide 131 through the second light-inlet end 1301, reducing the refraction and scattering loss of light when entering the light guide and ensuring the efficiency of the initial entry of light. The second segment 1312 extends forward and is tilted in the height direction. The second segment 1312 serves as a transition and deflection point for the light. The tilted setting of the second segment 1312 in the height direction allows the near light entering from the first segment 1311 to gradually change direction through reflection during propagation, better adapting to the transmission requirements of the subsequent optical path and ensuring the stability and continuity of the near light propagation inside the first light guide 131. The third segment 1313 extends horizontally and connects to the second light guide 132. The horizontal extension design of the third segment 1313 provides a smooth transition for the light to smoothly enter the second light guide 132 from the first light guide 131, ensuring that the near light can enter the second light guide 132 in a more ideal state, thereby realizing the effective transmission and final illumination of the near light within the lens assembly 1, improving the utilization efficiency and illumination effect of the entire lens assembly 1 for near light.

[0032] The segmented structural design makes the propagation path of the low beam within the first light guide 131 more controllable. The shapes and extension directions of different segments work together to adjust the light through multiple refractions and reflections. For example, the inclined extension of the second segment 1312 can change the distribution of the low beam in the height direction as needed, thereby affecting the shape and range of the final beam pattern in the vertical direction. Through precise design of the dimensions and angles of each segment, different beam patterns can be accurately shaped to meet the stringent requirements of vehicle lighting for different beam patterns such as low beam and high beam.

[0033] According to one embodiment of the present invention, the second light-gathering end 1301 is constructed as an inclined surface arranged relative to the front-back direction, at least a portion of the wall surface of the first segment 1311 is formed with a first total reflection surface 151, and at least a portion of the wall surface of the second segment 1312 is constructed as a second total reflection surface 152. For example... Figure 2 As shown, the second light-inlet end 1301 is constructed as an inclined surface with a relative front-to-back orientation, which can correspondingly adjust the position of the second light-emitting element 14 so that the near light emitted by the second light-emitting element 14 is perpendicularly incident on the second light-inlet end 1301, ensuring that most of the light from the second light-emitting element 14 can enter the first light guide 131. At least a portion of the wall surface of the first segment 1311 is constructed as a first total internal reflection surface 151, while at least a portion of the wall surface of the second segment 1312 can be constructed as a second total internal reflection surface 152. The first total internal reflection surface 151 and the second total internal reflection surface 152 correspond to each other. The near light entering the first segment 1311 is reflected on the first total internal reflection surface 151 and can be directed towards the second total internal reflection surface 152. The near light after passing through the second total internal reflection surface 152 can enter the third segment 1313. The arrangement of the first total internal reflection surface 151 and the second total internal reflection surface 152 reduces the scattering and energy loss of the near light between the first segment 1311 and the second segment 1312, ensuring that the near light can efficiently enter the subsequent optical processing stage.

[0034] In actual and assembled applications, the tilt angle of the second light-receiving surface can be adjusted to 30° relative to the X-axis of the vehicle body. This 30° tilt angle can maximize the efficiency of the first total reflection surface 151 reflecting the near-light rays onto the second total reflection surface 152, further reducing the scattering and energy loss of the near-light rays.

[0035] According to one embodiment of this utility model, the first total reflection surface 151 is constructed as an arc-shaped surface convex away from the first segment 1311. The arc-shaped surface can focus light. When low beam light is incident on the first total reflection surface 151, the shape of the arc-shaped surface can focus the dispersed light like a convex lens, making the light more concentrated and reflected onto the second total reflection surface 152. Compared with a planar reflection surface, the focusing effect of the arc-shaped surface can reduce the divergence of light during the reflection process, allowing more light to propagate in a predetermined direction, thereby improving the transmission efficiency of low beam light inside the first light guide 131. Moreover, this focusing effect can also enhance the final illumination intensity of the low beam light, enabling the low beam to illuminate a farther and wider road surface when the vehicle is driving at night, providing the driver with better visibility and improving driving safety.

[0036] According to one embodiment of this utility model, the second segment 1312 is constructed as a second total reflection surface 152 on both sides in the height direction. Both walls of the second segment 1312 in the height direction are also constructed as second total reflection surfaces 152. When the first total reflection surface 151 transmits low beam light, the low beam light first strikes the second total reflection surface 152 located at the bottom of the second segment 1312, and after reflection, strikes the second total reflection surface 152 located at the top of the second segment 1312, and after another reflection, enters the third segment 1313. The arrangement of the two second total reflection surfaces 152 changes the propagation path of the low beam light in the height direction, ensuring that the low beam light enters the second light guide 132, facilitating the low beam illumination of the vehicle. The second segment 1312, through the two total reflection surfaces, makes the propagation direction of the low beam light more in line with design requirements, and can reduce the scattering and energy loss of the low beam light during its transmission within the second segment 1312, not only improving the light transmission efficiency but also enhancing the uniformity and stability of the illumination effect. In practical applications, the length of the second segment 1312 in the height direction and the angle of the two second total reflection surfaces 152 can be flexibly adjusted according to different lighting needs and vehicle designs to achieve the best light pattern and illumination range.

[0037] According to one embodiment of the present invention, the lens assembly 1 further includes a partition 16, which is disposed between the first light-emitting end 112 and the third light-entry end 1302, and separates the first light guide 131 from the first lens 11. In the lens assembly 1, the first light guide 131 and the first lens 11 perform different optical functions, and the light propagation paths and characteristics inside them are different. The partition 16 can block the light propagating in the first lens 11 from directly entering the first light guide 131, avoiding mutual interference between the two light sources. This effectively prevents stray light caused by ADB light from the first lens 11 entering the first light guide 131, thus improving the quality of the final light output pattern of the lens assembly 1.

[0038] According to one embodiment of the present invention, the first lens 11 has a plurality of light guide teeth 1111 spaced apart from each other formed at the first light-inlet end 111, and the first light-emitting element 12 is provided with a plurality of light-emitting units 121, each light-emitting unit 121 corresponding to a light guide tooth 1111. Figure 3As shown, the first light-inlet end 111 is provided with multiple spaced-apart light guide teeth 1111. Correspondingly, the first light-emitting element 12 is provided with multiple spaced-apart light-emitting units 121. Each light-emitting unit 121 corresponds one-to-one with a light guide tooth 1111, ensuring that the light emitted by each light-emitting unit 121 can be effectively collected and guided by the corresponding light guide tooth 1111. These light guide teeth 1111 can both converge the light from the light-emitting units 121 and prevent light leakage between adjacent light-emitting units 121, so that the ADB high beam light emitted by the first light-emitting element 12 can enter the first lens 11 more accurately and orderly. Through this corresponding arrangement of the light guide teeth 1111 and the light-emitting units 121, the initial efficiency of light entering the first lens 11 is greatly improved, and the scattering and energy loss of light during the entry stage are reduced. This lays a good foundation for the effective convergence and refraction of light in the first lens 11, thereby ensuring that the high beam light emitted from the first light-outlet end 112 has high intensity and quality to meet the requirements of vehicle ADB high beam lighting. Meanwhile, the design of the light guide teeth 1111 also enhances the control of the entire lens assembly 1 over the high beam, which helps to achieve a more ideal ADB beam pattern and improve the performance of the vehicle lighting system.

[0039] In some embodiments, total reflection surfaces may be formed on both sides of the first lens 11 in the height direction, wherein the total reflection surface located on the lower side may be a plane and have an angle of 45° with the water direction; the total reflection surface located on the upper side may be a plane or a curved surface.

[0040] In some embodiments, the front-to-back depth of each light guide tooth 1111 can be 2mm~3mm, the left-to-right width can be 1.2mm~1.5mm, and the top-to-bottom length can be 5mm~10mm.

This reduces the number of parts, lowers the cost and reduces assembly deviation, and can achieve better ADB beam pattern and low beam while ensuring high light efficiency, thereby improving the performance and safety of the vehicle lighting system.
