Description

Technical Field

[0001] The present invention relates to a vehicle lamp, and in particular to an ADB vehicle lamp module. The present invention also relates to a vehicle lamp and a vehicle. Background Art

[0002] High beams can provide a bright and wide illumination range, providing drivers with a wider field of vision when driving at a higher speed on roads with poor lighting and few vehicles. However, when there are many vehicles on the road, or when meeting or following a vehicle, if the high beam is not switched to low beam in time, the high beam lighting will cause dazzle to the drivers of other vehicles on the road, and switching from high beam to low beam will also cause the field of vision in front of the vehicle to become smaller, which can easily cause traffic accidents.

[0003] Adaptive high beam (ADB) uses light from multiple high beam sources to provide high beam illumination. The illumination area formed by the light from each high beam source is called a pixel, and multiple pixels are combined to form a high beam light pattern. The ADB system can control the corresponding pixels in the high beam light pattern to turn off according to the position and distance of the vehicle in front, thereby avoiding dazzle to the driver of the vehicle in front or the other vehicle caused by high beam illumination, and improving driving safety.

[0004] An existing ADB headlight module is as follows Figure 1 As shown, it includes multiple high-beam light sources 1, micro lenses 2, cylindrical lenses 31 and lenses 4. Multiple high-beam light sources 1 are arranged left and right, and the pixels formed by each high-beam light source 1 are arranged left and right, which expands the illumination range in the width direction of the high-beam light shape. The cylindrical lens 31 diffuses the light emitted by the high-beam light source 1 in the vertical direction to form a high-beam light shape. Figure 2 The pixel light shape shown is elongated in both the vertical direction, which expands the illumination range of the high beam light shape in the height direction. However, this technical solution makes the lower boundary of the high beam light shape too low, and the illumination brightness near the vehicle is too high, which affects the driver's observation of the distant illumination area. At the same time, the diffusion of the illumination range reduces the illumination of the middle area of ​​the pixel light shape, affecting the high beam lighting effect. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an ADB vehicle light module, wherein the pixel light shape formed by the vehicle light module is reasonable and the brightness of the middle area of ​​the pixel is high.

[0006] A further technical problem to be solved by the present invention is to provide a vehicle lamp having a more reasonable high beam lighting shape and a good high beam lighting effect.

[0007] The technical problem to be solved by the present invention is to provide a vehicle, the high beam lighting light shape of the vehicle headlight is reasonable, the high beam lighting effect is good

[0008] In order to solve the above technical problems, the present invention provides an ADB headlight module, including multiple high-beam light sources, microlenses, semi-cylindrical lenses and lenses; the multiple high-beam light sources are arranged linearly and are suitable for independent control of lighting, the microlens includes multiple linearly arranged focusing units, each of the focusing units is arranged corresponding to one of the high-beam light sources; the semi-cylindrical lens is the lower half of a cylindrical lens whose cylindrical axis is consistent with the arrangement direction of the high-beam light sources, the semi-cylindrical lens is located in front of the lower half of the microlens, and the lens is located in front of the semi-cylindrical lens.

[0009] Preferably, the microlens includes a microlens light incident surface, a microlens light exit surface, a microlens upper side surface and a microlens lower side surface; the microlens light incident surface, the microlens upper side surface and the microlens lower side surface are all planes, and the microlens light exit surface portion corresponding to each of the light-concentrating units respectively forms a curved surface convex forward, and the left and right widths of each curved surface gradually decrease from the inside to the outside. Through this preferred technical solution, light can enter the microlens from the microlens light incident surface, and after being converged by the microlens, it is emitted from the microlens light exit surface. The structure in which the left and right widths of the curved surface corresponding to each light-concentrating unit in the microlens gradually decrease from the inside to the outside can make the width of the pixel light shape formed by each high-beam light source gradually increase from the inside to the outside, so that the high-beam lighting light shape has a higher pixel resolution at the position directly in front of the vehicle, and a lower pixel resolution at the outer position of the vehicle, while realizing the ADB function while reducing the impact of the dark area on the road lighting. The upper side surface and the lower side surface can limit the lighting range of the high-beam light source.

[0010] Further preferably, the upper side surface of the microlens is a plane inclined upward at the front, and the lower side surface of the microlens is a plane inclined downward at the front. In this preferred technical solution, the inclined arrangement of the upper side surface of the microlens and the lower side surface of the microlens can form a trumpet-shaped structure that is wide at the front and narrow at the back on a vertical plane, and the height range of the formed pixel light shape can be adjusted by adjusting the inclination of the upper side surface of the microlens and the lower side surface of the microlens, thereby improving the illumination of the middle area of ​​the pixel light shape.

[0011] Preferably, the semi-cylindrical lens is a plano-convex cylindrical lens with a flat light incident surface. Through this preferred technical solution, the plane light incident surface of the semi-cylindrical lens can reduce the reflection of the incident light and improve the high beam light effect.

[0012] Preferably, the optical axis of each of the light-gathering units is located on the optical axis plane of the semi-cylindrical lens. In this preferred technical solution, the semi-cylindrical lens can generally be regarded as formed by cutting a cylindrical lens along the optical axis plane, and the light passing through the optical axis of the light-gathering unit also passes through the optical axis plane of the semi-cylindrical lens, and the light does not refract when passing through the optical axis or the optical axis plane of the lens, which enables the light passing through the upper and lower optical axis planes of the semi-cylindrical lens to smoothly transition.

[0013] Further preferably, the light emission center of each high-beam light source is located at a set distance below the optical axis of the lens. Through this preferred technical solution, the pixel light shape formed by the light emitted by the high-beam light source after passing through the microlens and the semi-cylindrical lens is biased toward the lower part of the lens as a whole, and the pixel light shape formed after being projected by the lens moves upward as a whole, which can further raise the lower boundary of the pixel light shape and move the center of the pixel light shape upward.

[0014] Preferably, the high-beam light source, microlens and semi-cylindrical lens are integrally rotated downward at a set angle around the light-emitting center of the high-beam light source on a vertical plane in the front-rear direction. In this preferred technical solution, the light emitted by the high-beam light source is converged and refracted by the microlens and the semi-cylindrical lens to form an irradiation direction inclined downward at a set angle, and after refraction by the lens, the pixel light shape formed is moved upward as a whole.

[0015] Preferably, the ADB headlight module of the present invention further includes a lighting light source and a lighting optical element, wherein the lighting optical element is disposed between the lighting light source and the lens so as to collect the light emitted by the lighting light source and transmit the light to the lens after being transmitted by the lighting optical element, thereby forming a lighting light. In this preferred technical solution, the light emitted by the lighting light source can be irradiated onto the lighting optical element, and after being refracted and transmitted by the lighting optical element, it is irradiated onto the lens, thereby forming a lighting light, thereby forming an appearance effect that the lens can still be illuminated in the low beam lighting mode.

[0016] Further preferably, the lighting optical element includes a lighting light incident surface, a lighting light-through portion, and a lighting light-emitting surface, wherein the lighting light incident surface is a plane located at the rear end of the lighting optical element, the lighting light-emitting surface is a forwardly protruding arc surface located at the front end of the lighting optical element, the lighting light-through portion is located between the lighting light incident surface and the lighting light-emitting surface, and both sides of the lighting light-through portion are formed as planes intersecting behind the lighting light source. Through this preferred technical solution, the light emitted by the lighting light source can enter the lighting optical element from the lighting light incident surface at the rear end of the lighting optical element, be transmitted by the lighting optical element, be emitted from the lighting light-emitting surface, and illuminate the lens. The forwardly protruding arc-shaped lighting light-emitting surface can scatter the light, so that the light emitted by the lighting light source can illuminate the entire surface of the long and narrow lens.

[0017] Furthermore, the light-emitting surface is provided with vertical concave and convex stripes. In this preferred technical solution, the vertical concave and convex stripes on the light-emitting surface can scatter the light emitted through the light-emitting surface, thereby improving the uniformity of the light.

[0018] Preferably, the lighting optical element further comprises a lighting mounting portion, the lighting mounting portion is arranged on both sides of the lighting light-through portion, and an air gap is arranged between the lighting light-through portion and the lighting mounting portion. In this preferred technical solution, the lighting optical element can be mounted and fixed by the lighting mounting portion, and the air gap can form a total reflection of the light irradiated onto the side wall of the lighting light-through portion, thereby limiting the irradiation range of the lighting light and improving the light effect of the lighting light.

[0019] Preferably, the ADB headlight module of the present invention further comprises an optical unit bracket, the microlens is integrally formed in the middle of the optical unit bracket, a lighting optical element mounting plate is disposed on the upper portion of the optical unit bracket, and a cylindrical lens mounting hole for mounting the semi-cylindrical lens is disposed on the lower portion of the optical unit bracket. Through this preferred technical solution, the structure in which the microlens is integrally formed in the middle of the optical unit bracket makes the positioning between the microlens and the optical unit bracket more precise and the structural stability is also higher. The provision of the lighting optical element mounting plate and the cylindrical lens mounting hole enables both the lighting optical element and the semi-cylindrical lens to be mounted on the optical unit bracket, thereby improving the accuracy of the positioning of the microlens, the cylindrical lens and the lighting optical element relative to each other.

[0020] A second aspect of the present invention provides a vehicle lamp, comprising the ADB vehicle lamp module provided by the first aspect of the present invention.

[0021] A third aspect of the present invention provides a vehicle, comprising the vehicle lamp provided by the second aspect of the present invention.

[0022] Through the above technical scheme, the ADB headlight module of the present invention, the multiple high-beam light sources arranged linearly can light up and extinguish independently, respectively forming a pixel in the high-beam illumination light shape, forming an ADB function. The multiple focusing units on the microlens can respectively converge the light emitted by the corresponding high-beam light sources, and form a pixel light shape after projection by the lens. The semi-cylindrical lens can elongate half of the pixel light shape, and after projection by the lens, a pixel light shape with a larger upper boundary deflection angle and a smaller lower boundary deflection angle is formed, which expands the illumination range of the pixel light shape in the height direction and raises the lower boundary of the pixel light shape. The illumination range of the high-beam illumination light shape formed is more reasonable, and the brightness of the middle area of ​​the pixel light shape is increased, and the high-beam illumination effect is better. Since the headlight of the present invention uses the ADB headlight module of the present invention, the vehicle of the present invention uses the headlight of the present invention, and also has the above advantages.

[0073] In the present invention, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "front, rear, up, down, left, right, horizontal, vertical" are based on the directions or positional relationships of the headlights of the present invention after they are normally installed on a vehicle. Among them, the direction indicated by the directional word "front" is the normal driving direction of the vehicle; the direction indicated by the directional word "vertical" is the direction perpendicular to the horizontal plane. The description of the directions or positional relationships of the ADB headlight module and its components of the present invention is consistent with the directions in which they are installed on a vehicle in actual use.

[0074] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting" or "connection" should be understood in a broad sense. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments.

[0076] like Figures 3 to 8 As shown, an embodiment of the ADB headlight module of the present invention includes a plurality of high-beam light sources 1, a microlens 2, a semi-cylindrical lens 3 and a lens 4. The plurality of high-beam light sources 1 are arranged in a straight line or a curve with a small curvature. The light emitted by each high-beam light source 1 can form a lighting area respectively. The lighting areas formed by each high-beam light source 1 are combined to form an overall high-beam lighting light shape. The lighting area formed by each high-beam light source 1 is called a pixel of the high-beam lighting light shape. Each high-beam light source 1 can independently control the brightness and darkness of each pixel in the high-beam lighting light shape, forming an ADB function. The microlens 2 includes a plurality of linearly arranged focusing units, which are formed into a convex lens structure. Each focusing unit corresponds to a high-beam light source 1, and can converge the light emitted by each high-beam light source 1 to form a pixel with a clear boundary. The semi-cylindrical lens 3 is half of a cylindrical lens. Of course, the semi-cylindrical lens 3 mentioned in the present invention is half of a cylindrical lens and does not require its accuracy. The semi-cylindrical lens 3 can be an approximate half of a cylindrical lens. Specifically, the cylindrical lens is a convex lens whose light incident surface and / or light emitting surface is a cylinder. The cylinder is a curved surface formed by the parallel movement of an arc along a straight line direction. The plane formed by the movement of the chord of the arc can be called the chord plane, and the straight line formed by the movement of the midpoint of the chord is called the cylindrical axis. The semi-cylindrical lens 3 is formed by equally splitting the cylindrical lens through the cylindrical axis in a direction perpendicular to the chord plane. The cylindrical axis of the semi-cylindrical lens 3 is consistent with the arrangement direction of the high-beam light source 1, and its split surface is set upward. The semi-cylindrical lens 3 is set in front of the microlens 2 and relative to the lower half of the microlens 2. After the light emitted by the high-beam light source 1 is converged by the microlens 2, the light emitted from the lower half of the microlens 2 is emitted to the semi-cylindrical lens 3, and after being refracted by the semi-cylindrical lens 3, it is emitted to the lens 4 set in front of the semi-cylindrical lens 3. The light emitted from the upper half of the microlens 2 is directly emitted to the lens 4. After being projected by the lens 4, it is formed as shown in the figure. Fig. 9 The pixel light shape shown. Fig. 9It can be seen that the deflection angle of the upper boundary 52 of the pixel light shape is larger, while the deflection angle of the lower boundary 53 of the pixel light shape is smaller, and the upper half of the pixel light shape is obviously elongated, forming a larger illumination range of the pixel light shape in the height direction; the lower half of the pixel light shape is not elongated, and thus the lower boundary position of the pixel light shape is higher, which avoids the high beam illumination light from irradiating a position close to the front of the vehicle and affecting the observation effect of the distant road surface, and improves the illumination brightness of the middle area 54 of the pixel light shape.

[0077] pass Fig.10 and Fig.12 The ADB headlight module shown can further illustrate the role of the semi-cylindrical lens 3. Fig.10 As shown, the light emitted by the high beam light source 1 is converged by the micro lens 2 and then emitted to the cylindrical lens 31, and then refracted by the cylindrical lens 31 and then emitted to the lens 4, and then projected by the lens 4 to form a Fig.11 The pixel light shape shown. Fig.11 In the pixel light shape shown, the upper boundary 52 of the pixel light shape is significantly raised, the lower boundary 53 of the pixel light shape is symmetrically depressed, and the upper and lower parts of the pixel light shape are symmetrically elongated, forming a larger illumination range of the pixel light shape in the height direction, and the illumination of the brightest part of the pixel light shape is 46.5lx. Fig.12 In the ADB headlight module shown in the figure, while maintaining Fig.10 In the case where other settings of the ADB headlight module shown in the figure remain unchanged, only the cylindrical lens 31 is replaced by a semi-cylindrical lens 3. The semi-cylindrical lens 3 only refracts the light emitted from the lower half of the micro lens 2, and finally forms the following Fig.13 The pixel light shape shown. Fig.13 In the pixel light shape shown, the upper boundary 52 of the pixel light shape is significantly raised, the lower boundary 53 of the pixel light shape is slightly depressed, the upper half of the pixel light shape is significantly elongated, and the lower half of the pixel light shape is not significantly stretched. The illumination range of the upper part of the pixel light shape formed is larger, and the lower boundary of the lower illumination area is significantly raised, so that the high beam light is more irradiated to the area farther away from the vehicle, avoiding the high brightness light irradiated in front of the vehicle affecting the driver's observation of the distant illumination area. At this time, the illumination of the brightest part of the pixel light shape is 79.9lx, and the brightness of the central area of ​​the pixel light shape is significantly improved.

[0078] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 3-Figure 8As shown, the microlens 2 includes a microlens light incident surface 21, a microlens light exit surface 22, a microlens upper side surface 23 and a microlens lower side surface 24. The microlens light incident surface 21, the microlens upper side surface 23 and the microlens lower side surface 24 are all a plane, that is, the light incident surfaces of each light-collecting unit on the microlens 2 are formed into the same plane, and the upper side surface and the lower side surface of each light-collecting unit are also formed into the same plane respectively; the microlens light exit surface 22 is composed of a plurality of curved surfaces convex forward, and each light-collecting unit corresponds to a curved surface convex forward, so that each light-collecting unit forms a convex lens. The shape of the curved surface can be freely set according to the shape of the required pixel light shape, and can be set to a spherical surface, an ellipsoidal surface or a free curved surface, etc. The left and right width of the curved surface corresponding to the light-collecting unit located on the inner side of the microlens 2 is greater than the left and right width of the curved surface corresponding to the light-collecting unit located on the outer side, that is, the spacing between the high-beam light sources 1 located on the inner side is larger, while the spacing between the high-beam light sources 1 located on the outer side is smaller. In this way, after projection by the lens 4, the width of the pixel light shape located on the inner side of the vehicle, that is, close to the front of the vehicle, is smaller, while the width of the pixel light shape located on the outer side of the vehicle, that is, far from the front of the vehicle, is larger. At this time, the portion of the high-beam lighting light shape formed close to the front of the vehicle has a higher pixel resolution, while the portion of the high-beam lighting light shape located on the outer side of the vehicle has a lower pixel resolution. When the ADB function is implemented and a certain high-beam light source 1 is turned off, the dark lighting area formed in front of the vehicle is smaller, while the dark lighting area formed on the side of the vehicle is larger, which can reduce the impact of the dark lighting area on driving safety.

[0079] As a specific implementation of the ADB vehicle lamp module of the present invention, Fig.18 As shown, the upper side surface 23 of the microlens is a plane inclined upward at the front, and the lower side surface 24 of the microlens is a plane inclined downward at the front, so that the rear height of the microlens 2 is smaller and the front height is larger. The upper side surface 23 of the microlens and the lower side surface 24 of the microlens extend and intersect at the rear of the high-beam light source 1. Such a structure enables more light emitted by the high-beam light source 1 to be totally reflected at the upper and lower sides of the microlens, and enables more light to participate in forming the pixel light shape. The light efficiency of the high-beam light source 1 is higher, and the brightness of the formed pixel light shape is higher. Of course, one of the upper side surface 23 of the microlens and the lower side surface 24 of the microlens can be set to be inclined and the other to be set to be straight, but the effect of such a setting is slightly worse.

[0080] pass Fig.19 and Fig.21 The ADB headlight module shown in the figure can illustrate the functions of the upper and lower sides of the microlens in this embodiment. Fig.19In the ADB headlight module shown in the figure, the upper side surface 23 and the lower side surface 24 of the microlens 2 are arranged in parallel. The light emitted by the high beam light source 1 is converged by the microlens 2, and part of the light is refracted by the semi-cylindrical lens 3 and then emitted to the lens 4. The projection of the lens 4 forms a Fig. 20 The pixel light shape shown. Part of the light emitted by the high-beam light source 1 is irradiated to the upper side surface 23 or the lower side surface 24 of the microlens set in parallel, and is emitted from the light-emitting surface 22 of the microlens after being reflected by the upper side surface 23 or the lower side surface 24 of the microlens, participating in the formation of the pixel light shape. The parallel arrangement of the upper side surface 23 and the lower side surface 24 of the microlens allows the high-beam light source 1 to irradiate more light on the upper and lower sides of the microlens 2, while the light irradiated on the upper and lower sides of the microlens 2 will produce a certain loss after being reflected by the upper and lower sides. Therefore, the brightness of the pixel light shape formed is relatively low. Fig. 20 As shown, the highest value of illumination in the pixel light shape is 79.9lx. Fig.21 The ADB headlight module shown will only Fig.19 The microlens 2 in the ADB headlight module shown is replaced with a microlens 2 with an upper side 23 and a lower side 24 of the microlens tilted. Since the upper side 23 and the lower side 24 of the microlens tilt upward and downward respectively in the process of extending from the back to the front, the light emitted by the high-beam light source 1 is more directly irradiated onto the microlens light-emitting surface 22. The incident angle of the light irradiated onto the upper side 23 and the lower side 24 of the microlens is also larger, the reflectivity of the light is higher, and it is easier to form total reflection. Therefore, the brightness of the pixel light shape formed is higher. The pixel light shape formed is as follows: Fig. 22 As shown, the highest value of illumination in the pixel light shape is 81.2lx, which is higher than Fig. 20 The highest illumination in the mid-pixel light shape.

[0081] In a specific embodiment of the ADB vehicle lamp module of the present invention, Figure 3-Figure 8 As shown, the semi-cylindrical lens 3 is a plano-convex cylindrical lens with a flat light incident surface. The use of a semi-cylindrical lens 3 with a flat light incident surface is more convenient for processing, and compared with a double convex cylindrical lens, the flat light incident surface reflects less incident light and has a higher light efficiency. In the ADB headlight module of the present invention, the semi-cylindrical lens 3 is arranged at a position slightly inside the lens 4. Therefore, in the ADB headlight module for the left and right headlights, the semi-cylindrical lens 3 needs to be arranged at different positions. As a preferred solution, a semi-cylindrical lens 3 with a longer length can be used so that the position of the semi-cylindrical lens 3 covers the required positions in the left and right headlights. In this way, the headlight modules for the left and right headlights can use the same semi-cylindrical lens 3 and lens 4. Only by replacing different microlenses 2 and light sources 1 can the conversion of the left and right headlights be completed, and the ADB headlight module has higher versatility.

[0082] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 3-Figure 8 As shown, the light emission center of the high-beam light source 1 is located on the optical axis 25 of the respective focusing unit. Since each focusing unit is a convex lens structure, each focusing unit has an optical axis, namely, the optical axis 25 of the focusing unit. The high-beam light source 1 is arranged on the optical axis 25 of the focusing unit, and the light emitted from the center of the high-beam light source 1 along the optical axis 25 of the focusing unit is not deflected when passing through the focusing unit, and the light emitted by the high-beam light source 1 is evenly distributed around the optical axis 25 of the focusing unit. At the same time, each focusing unit optical axis 25 is arranged on the optical axis plane of the semi-cylindrical lens 3. When parallel light rays are emitted toward the semi-cylindrical lens 3 in a direction perpendicular to the chord plane of the cylinder on the semi-cylindrical lens 3, they will converge on the other side of the semi-cylindrical lens 3 into a focal line parallel to the cylindrical axis of the semi-cylindrical lens 3. The plane where the focal line and the cylindrical axis are located is called the optical axis plane of the semi-cylindrical lens 3. The optical axis of the focusing unit is set on the optical axis plane of the semi-cylindrical lens 3. After the light emitted by the high-beam light source 1 is emitted through the focusing unit, the half located below the optical axis plane passes through the semi-cylindrical lens 3, and the half located above the optical axis plane does not pass through the semi-cylindrical lens 3, forming a pixel light shape in which the upper half is stretched and the lower half is not stretched. Half of the light emitted by the high-beam light source 1 is stretched in the vertical direction by the semi-cylindrical lens 3, and the height range of the irradiation is wider; the other half of the light is not stretched by the semi-cylindrical lens 3, and the irradiation brightness is higher.

[0083] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 3-Figure 8 As shown, the luminous center of each high-beam light source 1 is arranged on the corresponding focusing unit optical axis 25, and the focusing unit optical axis 25 is located below the lens optical axis 41, and the distance between the lens optical axis 41 and each focusing unit optical axis 25 in the vertical direction is L. It should be noted that the arrangement direction of each high-beam light source 1 may not be horizontal. In this case, the average distance between the focusing unit optical axis 25 corresponding to each high-beam light source 1 and the lens optical axis 41 in the vertical direction is controlled to be L. By setting the focusing unit optical axis 25 below the lens optical axis 41, the position of the light emitted by the high-beam light source 1 irradiating the lens 4 can be moved downward as a whole. After being projected by the lens 4, the position of the pixel light shape formed is shifted upward as a whole, and the position of the high-beam light shape formed is more reasonable. The vertical distance L of the focusing unit optical axis 25 from the lens optical axis 41 is usually set to 0.2-1mm, and is set to 0.5mm in this embodiment.

[0084] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 3-Figure 8As shown, the high-beam light source 1, the microlens 2 and the semi-cylindrical lens 3 are rotated as a whole in the vertical plane in the front-to-back direction around the luminous center of the high-beam light source 1 by an angle α, so that the side where the semi-cylindrical lens 3 is located is offset downward. In other words, the front part of the focusing unit optical axis 25 is rotated downward by an angle α around the luminous center of the high-beam light source 1 to reach the focusing unit optical axis rotation position 25'. If the luminous centers of the various high-beam light sources 1 are not on the same horizontal straight line in the left-right direction, a high-beam light source 1 can be selected as needed, and the horizontal straight line in the left-right direction where its luminous center is located is used as the rotation axis. The rotation angle α can be set according to the actual light shape boundary to be achieved, usually set to less than 10°, and is set to 4° in the present embodiment.

[0085] pass Fig.14 and Fig.16 The ADB headlight module shown in the figure can illustrate the effect of the rotation of the high beam light source 1 and the micro lens 2 in this embodiment. Fig.14 In the ADB headlight module shown, the light emission center of the high beam light source 1, the center of a focusing unit of the micro lens 2 and the center of the lens 4 are arranged on the same horizontal plane, that is, the optical axis of the focusing unit of the micro lens 2 coincides with the optical axis of the lens 4, and the light emission center of the high beam light source 1 is arranged on the optical axis of the focusing unit of the micro lens 2 and the lens 4. At this time, the pixel light shape formed by the light emitted by the high beam light source 1 is as follows: Fig.15 As shown. Fig.15 In the figure, the center of the pixel light shape is located on the H axis 51 of the projection screen, and the upper boundary 52 of the pixel light shape and the lower boundary 53 of the pixel light shape are symmetrical with respect to the H axis 51. Fig.16 The ADB headlight module shown is to maintain Fig.14 The position of the lens 4 in the ADB headlight module shown remains unchanged. Fig.14 The high-beam light source 1 and the microlens 2 in the ADB headlight module shown are formed by rotating counterclockwise at an angle α around the light emitting center of the high-beam light source 1 . Fig.16 The pixel light shape formed by the ADB headlight module shown is as follows Fig.17 As shown. Fig.17 In the embodiment, the pixel light shape is shifted upward as a whole, so that the center of the pixel light shape is located above the H axis, and the positions of the upper boundary 52 of the pixel light shape and the lower boundary 53 of the pixel light shape are both raised upward.

[0086] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 23-Figure 29As shown, the ADB headlight module of the present invention further includes a lighting light source 11 and a lighting optical element 6. The lighting light source 11 is arranged behind the lens 4, and the lighting optical element 6 is arranged between the lighting light source 11 and the lens 4. The light emitted by the lighting light source 11 is collected, refracted and transmitted by the lighting optical element 6 and then emitted to the lens 4, forming a lighting light emitted through the light exiting surface of the lens 4, so that when the high beam light source 1 of the ADB headlight module is turned off in the low beam lighting mode, the appearance of the lens 4 can still appear to be in a lighting state, thereby improving the visual effect of the vehicle.

[0087] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 23-Figure 29 As shown, the lighting optical element 6 includes a lighting light incident surface 61, a lighting light-through portion 62, and a lighting light-emitting surface 63. The lighting light incident surface 61 is a plane, and the incident light path of the planar lighting light incident surface 61 is simple, easy to control, and convenient to manufacture. The lighting light incident surface 61 is located at the rear end of the lighting optical element 6 close to the lighting light source 11, and the lighting light-emitting surface 63 is a forward-convex arc surface located at the front end of the lighting optical element 6, which can scatter the light emitted through the lighting light-emitting surface 63 so as to illuminate the entire light incident surface of the lens 4. The lighting light-through portion 62 is located between the lighting light incident surface 61 and the lighting light-emitting surface 63 to transmit the light incident through the lighting light incident portion 61 to the lighting light-emitting surface 63. The two sides of the light-transmitting portion 62 are formed into planar light-guiding boundaries, and the light-guiding boundary planes on both sides of the light-transmitting portion 62 intersect at the rear of the light source 11. The light introduced through the light-entering surface 61 can be more illuminated to the entire light-emitting surface 63 without being reflected by the side boundaries. The angle β between the light-guiding boundary planes on both sides can be set to 20-50°. In the preferred embodiment of this embodiment, it is set to 30-35°.

[0088] As a specific implementation of the ADB vehicle lamp module of the present invention, Figure 23-Figure 25 As shown, vertical concave and convex stripes are arranged on the light-emitting surface 63, and the vertical concave and convex stripes are evenly distributed on the light-emitting surface 63. The vertical concave and convex stripes can scatter the light passing through the light-emitting surface 63, so that the light-emitting light irradiating the lens 4 is more evenly distributed.

[0089] In some embodiments of the ADB vehicle lamp module of the present invention, Figure 23-Figure 29As shown, the lighting optical element 6 also includes a lighting mounting portion 64. The lighting mounting portion 64 is arranged outside the lighting light-through portion 62, on both sides of the lighting light-through portion 62. An air gap 65 is arranged between the lighting light-through portion 62 and the lighting mounting portion 64, so that the air gap 65 forms a boundary between the lighting light-through portion 62 and the lighting mounting portion 64. When the light passing through the lighting light-through portion 62 is irradiated to the side walls of the air gap 65 located on the left and right side walls of the lighting light-through portion 62, it can be totally reflected back to the lighting light-through portion 62, thereby increasing the amount of light irradiated to the lighting light-emitting surface 63, and improving the light effect of the lighting optical element 6.

[0090] As a specific implementation of the ADB vehicle lamp module of the present invention, Fig.30 and Fig.31 As shown, the ADB headlight module of the present invention also includes an optical unit bracket 7. The microlens 2 can be molded separately and installed in the middle of the optical unit bracket 7. The microlens 2 can also be integrally molded with the optical unit bracket 7 in the middle of the optical unit bracket 7 by insert injection molding or two-color injection molding. Inclined surfaces 77 can also be provided at the upper and lower sides of the light-emitting surface of the microlens 2 on the optical unit bracket 7. The setting of the inclined surface 77 can enable more light emitted by the microlens 2 to be emitted to the lens 4. A lighting optical element mounting plate 71 for mounting the lighting optical element 6 is also provided on the upper part of the optical unit bracket 7. A lighting unit positioning pin 73 and a lighting unit mounting hole 74 are also provided on the lighting optical element mounting plate 71. The lighting mounting portion 64 of the lighting optical element 6 is provided with a mounting hole and a positioning hole, and the positioning hole is used to cooperate with the lighting unit positioning pin 73 for positioning. The lighting optical element 6 is installed on the lighting optical element mounting plate 71 by screwing through the mounting hole on the lighting mounting portion 64 and screwing into the lighting unit mounting hole 74. The lower part of the optical unit bracket 7 is also provided with a cylindrical lens mounting hole 72 and a cylindrical lens positioning pin 75 for mounting the semi-cylindrical lens 3. The semi-cylindrical lens 3 is provided with a mounting hole and a positioning hole, and is positioned by cooperating with the cylindrical lens positioning pin 75. The semi-cylindrical lens 3 is mounted in front of the micro lens 2 on the optical unit bracket 7 by cooperating with the mounting hole and the cylindrical lens mounting hole 72. The high beam light source 1 and the lighting light source 11 are arranged on the circuit board 8. As a mounting method, screws are sequentially passed through the mounting holes on the heat sink 9, the mounting holes on the circuit board 8 and the bracket mounting holes 76 and are threadedly connected with the threaded holes on the lens bracket 42 to fix the lens bracket 42, the optical unit bracket 7, the circuit board 8 and the heat sink 9 together. The lens 4 is mounted on the front end of the lens bracket 42 to form the ADB vehicle light module of the present invention.

[0091] Through the above technical solution, the ADB headlight module of the present invention, the microlens 2 is set to converge the light emitted by the high-beam light source 1, so that more light can be irradiated on the lens 4, and can cooperate with the lens 4 to optimize the shape of the pixel light shape formed. The setting of the semi-cylindrical lens 3 can refract the lower light emitted by the high-beam light source 1 in the vertical direction, so that the upper part of the pixel light shape formed by the high-beam light source 1 is stretched, and the deflection angle of the upper boundary 52 of the pixel light shape is increased, and a pixel light shape with a larger deflection angle of the upper boundary and a smaller deflection angle of the lower boundary 53 of the pixel light shape is obtained. The lower boundary of the pixel light shape is increased, so that the high-beam light is irradiated more to the area far away from the vehicle, avoiding the high-brightness light irradiated in front of the vehicle affecting the driver's observation effect of the distant lighting area, and increasing the brightness of the pixel light shape. The luminous state of multiple high-beam light sources 1 can be controlled independently, and the brightness of each pixel light shape in the high-beam light shape can be controlled to realize the adaptive high-beam function. In a preferred embodiment of the ADB headlight module of the present invention, the arrangement of the curved surface areas of different focusing units on the microlens 2 enables different parts of the high-beam light source to have different pixel resolutions, thereby improving the ADB effect. The tilted arrangement of the upper and lower sides of the microlens 2 improves the brightness of the pixel light shape. The structure in which the lens optical axis 41 deviates from the light-emitting center of the high-beam light source 1 and the high-beam light source 1, microlens 2 and semi-cylindrical lens 3 rotate as a whole causes the formed pixel light shape to be raised upward as a whole, further optimizing the position of the high-beam lighting light shape and improving the high-beam lighting effect. The arrangement of the lighting light source 11 and the lighting optical element 6 improves the appearance of the ADB headlight module in the low-beam lighting mode. Compared to the above. Figure 2 The pixel light shape formed by the conventional ADB headlight module shown in FIG. 1 and the pixel light shape formed by the high beam light source 1 in the preferred embodiment of the present invention are as follows: Fig. 22 As shown, the deflection angle of the upper boundary 52 of the pixel light shape relative to the H axis 51 is between 4° and 10°, and the deflection angle of the lower boundary 53 of the pixel light shape relative to the H axis 51 is between 1° and 2°. The upper irradiation range of the light shape is farther, the lower irradiation boundary is higher, and the light irradiation is more concentrated; the maximum illumination of the central area 54 of the middle light shape of the pixel light shape is increased from 54.5lx to 81.2lx, and the brightness of the central area of ​​the light shape is higher. Therefore, the light distribution of the high-beam illumination light shape formed by the ADB headlight module of the present invention is more reasonable, and the high-beam illumination effect is better.
