It should be apparent that the embodiments described are some, but not all embodiments of the present application.

The specific meaning of the above terms in this application will be understood to be a specific case for those of ordinary skill in the art.

With the continued sophistication of the automotive industry, the market has no longer been satisfied solely with dynamic performance and ride comfort for consumer-type automobiles. In the current automobile market, consumers pay more and more attention to the shape of the automobile, meanwhile, the youth of automobile consumer groups also pushes the shape of the automobile to be sporty, and the streamline design is applied to the automobile industrial design more and more. In order to meet the streamlined design of an automobile body, the requirements on the shape and the size of an automobile lamp are more and more strict, and the market has more and more requirements on a narrow and long lens automobile lamp module.

In the prior art, the size of the lens of the car lamp module with a large light-emitting surface of the lens is directly reduced or the size of the optical element is reduced at the same time, so that the requirements of light shape, optical performance, optical efficiency and the like cannot be met. Meanwhile, in the prior art, the long and narrow lens car light module cannot be applied to an Adaptive high Beam lighting system (ADB).

In view of the above, the present application provides an optical element, a vehicle lamp module and a vehicle lamp. The optical element 1 of the present application is provided with the first reflection portion 11, the first reflection portion 11 is provided with the plurality of reflection units 111, each reflection unit 111 can reflect light, and the light irradiated to different reflection units 111 does not interfere with each other, so as to be adapted to the adaptive high beam illumination system. Meanwhile, the light emitting portion 14 of the optical element 1 extends along the second direction M, that is, the light emitting portion 14 is elongated along the second direction M, which is suitable for a moving automobile modeling trend and a vehicle lamp modeling trend.

In one aspect, as shown in fig. 1, the present application provides an optical element 1, where the optical element 1 includes a first reflective portion 11, a second reflective portion 12, and a light emergent portion 14.

As shown in fig. 1, in some embodiments of the present application, the first reflection part 11 is provided with a plurality of reflection units 111, and the plurality of reflection units 111 are arranged at intervals in the first direction N. The reflecting units 111 arranged at intervals can reflect light rays, and the light rays irradiating different reflecting units 111 do not interfere with each other, so that the self-adaptive high-beam illumination system can be suitable for. The second reflection portion 12 is used for reflecting the light reflected by the first reflection portion 11, and the light is reflected by the second reflection portion 12 and then irradiates the light emergent portion 14. The light emitting portion 14 extends along the second direction M, and the light emitting portion 14 is configured to transmit the light reflected by the second reflecting portion 12 and form a light shape.

It should be noted that, in fig. 1-10, the X direction is the left-right direction of the automobile, that is, the left-right direction of the optical element 1, the lamp module and the lamp of the present application; the Y direction is the front and back direction of the automobile, namely the front and back direction of the optical element 1, the automobile lamp module and the automobile lamp; the Z direction is the height direction of the vehicle, that is, the up-down direction of the optical element 1, the lamp module, and the lamp. The light emitting portion 14 is narrow and long, and it can be understood that the light emitting portion 14 has a large size in the left-right direction and a small size in the up-down direction, and the light emitting portion 14 is long in the left-right direction in visual effect, so that the light emitting portion can be applied to a trend of a sporty automobile model and a trend of a vehicle lamp model. It should be noted that, the size of the vehicle lamp is not limited in the present application, and the front-back size of the vehicle lamp may be smaller, for example, the front-back size of the vehicle lamp may be smaller than the left-right size of the vehicle lamp, or the front-back size of the vehicle lamp may be larger, for example, the front-back size of the vehicle lamp may be larger than the left-right size of the vehicle lamp.

The first direction N is a length direction of the first reflection portion 11, and an included angle is formed between the first direction N and a front-back direction (Y direction) of the vehicle, and the included angle may be 0 °, that is, the first direction N may be parallel to the front-back direction of the vehicle. The second direction M is a longitudinal direction of the light exit portion 14, that is, a left-right direction (X direction) of the automobile. The second direction and the first direction form an included angle.

The optical element 1 of the present application is provided with the first reflection portion 11 having the plurality of reflection units 111, and light rays irradiated to different reflection units 111 do not interfere with each other, so that the optical element 1 is suitable for an adaptive high beam illumination system. Meanwhile, the light emitting portion 14 of the optical element 1 extends along the second direction M, that is, the light emitting portion 14 is elongated along the second direction M, which is suitable for a moving automobile modeling trend and a narrow and long automobile lamp modeling trend.

The non-interference of the light beams irradiated to the different reflection units 111 means that the light beams emitted from the light source are only irradiated to the reflection unit 111 corresponding to the light source and are not irradiated to other reflection units 111, that is, the light beams irradiated to the different reflection units 111 do not generate the problem of light fleeing. The optical paths of the light beams reflected by the plurality of reflecting units 111 are independent of each other, and there is no overlapping area between the optical paths of the plurality of light beams. Further, after the light reflected by the first reflection part 11 is projected by the light emergent part 14, a plurality of pixel light-shaped areas 30 are formed, and the plurality of reflection units 111 correspond to the plurality of pixel light-shaped areas 30 one by one. When light enters one of the plurality of reflection units 111 and the light is reflected by the reflection unit 111 and projected by the light-emitting part 14, the pixel light shape area 30 corresponding to the reflection unit 111 will form a light shape; when no light is incident on one of the plurality of reflection units 111, the pixel light shape area 30 corresponding to the reflection unit 111 will not form a light shape.

Further, the light shape refers to a bright area formed by the vehicle light irradiating to a reference surface (such as the ground or a light distribution screen). For example, fig. 2 and 3 show the light shapes formed by the vehicle lights irradiating the light distribution screen. During the driving process of the vehicle, other road traffic users (such as oncoming vehicles, following vehicles, pedestrians, etc.) may appear in the irradiation range of the lamp, and in order to avoid traffic accidents caused by the direct irradiation of the lamp on other road traffic users, the high beam needs to be turned off. However, in a use scene with a poor road lighting environment, turning off the high beam may affect the line of sight of the driver. At this time, the adaptive high beam illumination system is applied to divide the light shape formed by the illumination of the vehicle lamp into a plurality of regions along the left-right direction, each region corresponds to one pixel light shape region 30, and each pixel light shape region 30 is independent from each other, that is, the projection of light to each pixel light shape region 30 can be controlled independently. When other road traffic users exist in one of the pixel light shape areas 30 which are irradiated by the vehicle lamp to form light shapes, no light is controlled to be projected to the corresponding pixel light shape area 30, and the other pixel light shape areas 30 are not interfered, so that the visual field of a driver is ensured. In the optical element 1 of the present application, since the plurality of reflection units 111 are independent from each other, light beams irradiated to different reflection units 111 do not interfere with each other, and correspondingly, the plurality of pixel light shape areas 30 corresponding to the plurality of reflection units 111 are also independent from each other, so as to be applicable to an adaptive high beam illumination system.

As shown in fig. 4 and 5, in some embodiments of the present application, a spacer 112 is disposed between two adjacent reflection units 111, so that light rays irradiated to different reflection units 111 do not interfere with each other, and thus the optical element 1 can be applied to an adaptive high beam illumination system. Since the light is scattered when the light enters the reflection units 111, the partition rib 112 is disposed between two adjacent reflection units 111 to prevent the light from the light source from irradiating on other reflection units 111 except the corresponding reflection unit 111, that is, the light irradiating on different reflection units 111 does not interfere with each other, so that the optical element 1 can be applied to an adaptive high beam illumination system.

As shown in fig. 4 and 5, in some embodiments of the present application, the sizes of the different reflection units 111 along the first direction N may have a certain difference to meet different width requirements of the pixel light shape area 30 for different positions. Alternatively, the dimensions may also be the same between different reflection units 111.

For example, in some embodiments of the present application, along the first direction N, the size of the reflection units 111 near the two ends of the first reflection portion 11 in the first direction N is larger, and the width (the size along the left-right direction) of the corresponding pixel light-shaped region 30 is correspondingly wider; in the first direction N, the reflective unit 111 located at the middle of the first reflective portion 11 has a smaller size in the first direction N, and the width of the corresponding pixel light-shaped region 30 is also narrower. In this arrangement, the pixel light-shaped areas 30 have different light-shaped widths, and it can be understood that the pixel light-shaped areas 30 near the middle area of the road have a narrow width and form light shapes with higher resolution, and the pixel light-shaped areas 30 far from the middle area of the road, i.e. both sides of the road, have a wide width and form light shapes with lower resolution. Since the driver needs to pay much attention to the road information in the middle area of the road, this arrangement can satisfy the driver's demand for the road information in the middle area of the road in a large amount when the dimension of the first reflection part 11 in the left-right direction is constant. In other embodiments of the present application, the sizes of the plurality of reflection units 111 along the first direction N may also be the same, and correspondingly, the widths of the pixel light-shaped areas 30 corresponding to the plurality of reflection units 111 are also the same. It should be noted that, the size of the plurality of reflection units 111 in the first direction N is not limited in the present application, and the size of the plurality of reflection units 111 in the first direction N may be adjusted accordingly according to actual situations.

Further, in some embodiments of the present application, the first reflection portion 11 is integrally formed by injection molding, that is, the reflection unit 111 and the spacer 112 are integrally formed. The integrally formed first reflection portion 11 ensures that the position relationship between the reflection unit 111 and the spacer 112 is easy to ensure, and the plurality of reflection units 111 are further ensured to be independent from each other because no gap is generated by connection between the reflection unit 111 and the spacer 112.

In other embodiments of the present application, the reflection unit 111 and the spacer 112 may be separately disposed and connected by snapping, bonding, or the like. For example, when the reflection units 111 are clamped with the spacer ribs 112, a groove may be provided between two adjacent reflection units 111, the spacer ribs 112 are provided with a protrusion corresponding to the groove, and the reflection units 111 are connected with the spacer ribs 112 through the matching between the groove and the protrusion, or a protrusion is provided between two adjacent reflection units 111, and the spacer ribs 112 are provided with a groove corresponding to the protrusion.

In other embodiments of the present application, a separation groove may be further disposed between two adjacent reflection units 111, and the two adjacent reflection units 111 are separated by the separation groove, and light may be irradiated into the separation groove, so that light irradiated to different reflection units 111 do not interfere with each other.

As shown in fig. 4 and 5, in some embodiments of the present application, the reflection unit 111 may be provided as a reflection curved surface. The curved reflective surface is configured to reflect and bundle light rays. The reflecting units 111 in the form of the reflecting curved surfaces can perform bundling and collimating functions on the light rays, so that the mutual influence among the reflecting units 111 is further reduced, and the mutual independence of the light paths of the light rays reflected by the reflecting units 111 is ensured. In other embodiments of the present application, the reflection unit 111 may also be disposed as a plane.

Furthermore, the reflecting curved surface can be an ellipsoid so as to play a good bundling and collimating effect on light rays. The ellipsoid has two focuses, and when the light is emitted from one of the two focuses, the light is reflected by the ellipsoid and then is converged at the other focus, so that the light is converged and collimated. In other embodiments of the present application, the curved reflective surface may also be a paraboloid, a hyperboloid, or a conical surface.

As shown in fig. 6, in some embodiments of the present application, the second reflection part 12 is configured to be able to reflect the light reflected by the first reflection part 11. Meanwhile, in order to reduce the size of the optical element 1 in the front-rear direction and improve the space utilization of the vehicle lamp, the second reflecting portion 12 is provided on the side of the first reflecting portion 11, and the longitudinal direction of the first reflecting portion 11 and the longitudinal direction of the second reflecting portion 12 have an angle.

Further, as shown in fig. 6, the included angle between the first reflection portion 11 and the second reflection portion 12 is an acute angle, so as to further reduce the size of the optical element 1, improve the compactness of the optical element 1, and improve the space utilization of the vehicle lamp in terms of meeting the requirements of vehicle lamp modeling.

As shown in fig. 6, in some embodiments of the present application, since the optical paths of the light beams reflected by the plurality of reflection units 111 are independent of each other, the second reflection portion 12 is configured as a plane, and the plane is only used for reflecting the light beams and does not concentrate or scatter the light beams, so that the optical paths of the light beams are still independent of each other after the light beams are reflected by the second reflection portion 12. In other embodiments of the present application, the second reflecting portion 12 may also be configured as a curved surface according to the requirement of the actual light shape.

As shown in fig. 4-6, in some embodiments of the present application, the light exit portion 14 is provided as a lens. The lens is configured to be able to transmit the light reflected by the second reflection part 12 and form a light shape. The lens has stronger light-gathering capacity, the light form formed by the transmission of the light rays through the lens is gathered, the discrete degree is low, the road surface is bright and clear when the light rays irradiate the road surface, the range of the light rays after being gathered by the lens can be far, the visual field range of a driver is good, and traffic accidents caused by the light rays can be reduced or avoided. Meanwhile, the light transmitted by the lens is uniform in brightness and strong in penetrating power, and can timely find oncoming vehicles, front vehicles, pedestrians and the like in rainy days, foggy days and other weather conditions with insufficient sight distance, and oncoming vehicles can timely find own vehicles, so that traffic accidents are reduced or avoided.

As shown in fig. 4-6, in some embodiments of the present application, the lens includes a lens incident surface 151 and a lens exiting surface 152, the lens incident surface 151 and the lens exiting surface 152 are disposed opposite to each other, and the lens exiting surface 152 is configured to serve as the light exiting portion 14 of the optical device 1. The light is reflected to the lens light incident surface 151 by the second reflection portion 12, and enters the lens from the lens light incident surface 151, and then passes through the lens and irradiates to the lens light emitting surface 152, and finally the lens light emitting surface 152 is used as the light emitting surface of the optical element 1, and the light is transmitted through the lens light emitting surface 152 and irradiates to a reference surface (such as the ground), and forms a light shape.

As shown in fig. 4-6, in some embodiments of the present disclosure, the lens light emitting surface 152 is a curved surface to collect light and realize a light condensing function.

Since the bundling and collimating effect of the reflection unit 111 is limited, and the second reflection portion 12 cannot bundle the light, the light incident on the lens is still relatively discrete. As shown in fig. 4-6, in some embodiments of the present application, the lens may be configured as a convex lens to further bundle the light rays entering the lens.

As shown in fig. 7 and 8, in other embodiments of the present application, the lens light emitting surface 152 may also form a convex curved surface along the height direction (Z direction) of the automobile, and it can also be understood that the lens light emitting surface 152 has an arch-shaped cross section along the vertical direction and is stretched along the left-right direction. The convex lens light-emitting surface 152 along the height direction (Z direction) of the automobile can converge the light along the up-down direction. Specifically, the light shape of the light projected onto the reference surface (for example, the ground) is clear along the traveling direction of the vehicle, that is, along the front-rear direction (Y direction) of the vehicle, and the light is emitted through the light emitting portion 14. In some embodiments of the present application, the form of the curved surface formed by the lens light exiting surface 152 may be combined with the form of the reflective curved surface of the reflective unit 111. For example, when the reflection curved surface of the reflection unit 111 is set as an ellipsoid, the lens light exiting surface 152 may be set as a curved surface protruding outward along the second direction M; when the reflection curved surface of the reflection unit 111 is a paraboloid, the lens light emitting surface 152 may be a curved surface protruding outward in the up-down direction. It should be noted that, according to the actual light shape requirement, the combination is not limited to the above-mentioned combination form, and the reflection unit 111 having an ellipsoidal surface may be combined with the lens light emitting surface 152 having a convex curved surface formed in the up-down direction.

As shown in fig. 1, 4, 5 and 6, in some embodiments of the present application, the first reflective portion 11, the second reflective portion 12 and the light exit portion 14 (e.g., a lens) may be separate components. In this case, the optical element 1 of the present application has the following light path: the light irradiates the plurality of reflection units 111 of the first reflection portion 11, the plurality of reflection units 111 reflect the light to the second reflection portion 12, the light is reflected to the light emergent portion 14 through the second reflection portion 12, and the light is emitted from the light emergent portion 14 to form a light shape. When the light emitting portion 14 is configured as a lens, the light is reflected to the lens light incident surface 151 by the second reflecting portion 12, and then passes through the inside of the lens and is emitted out through the lens light emitting surface 152 to form a light shape, where the lens light emitting surface 152 is the light emitting surface of the optical element 1.

As shown in fig. 7-10, in some embodiments of the present application, the optical element 1 further includes a light incident surface 13. After the light emitted from the light source 21 enters the optical element 1 through the light entrance surface 13, the light irradiates the first reflection portion 11, the plurality of reflection units 111 of the first reflection portion 11 reflect the light to the second reflection portion 12, and the second reflection portion 12 reflects the light to the light exit portion 14 and then exits, so as to form a light shape.

Further, as shown in fig. 7-10, the first reflection portion 11, the second reflection portion 12 and the light emitting portion 14 (e.g. lens) are integrated into a transparent light guide body, so that the optical element 1 has a compact structure and the space utilization of the vehicle lamp is improved. In this case, the optical element 1 of the present application has the following light path: the light enters through the light entrance surface 13 and irradiates to the plurality of reflection units 111 of the first reflection portion 11, the plurality of reflection units 111 reflect the light to the second reflection portion 12, the light is reflected to the light exit portion 14 through the second reflection portion 12, and the light exits from the light exit portion 14 to form a light shape. Since the optical element 1 is an integrally formed transparent light guide, the light is directly reflected to the lens light emitting surface 152 by the second reflection portion 12 and emitted out to form a light shape, and the lens light emitting surface 152 is the light emitting surface of the optical element 1.

As shown in fig. 7, in some embodiments of the present application, the light incident surface 13 is disposed at the bottom of the first reflection portion 11. With such an arrangement, the light incident surface 13 and the first reflection portion 11 are compact in structure, the space utilization rate of the car lamp is high, and on the basis of ensuring the light shape, the height of the optical element 1 does not need to be increased, that is, the size of the optical element 1 in the vertical direction (Z direction) does not need to be increased, so that the optical element 1 can be applied to the shape of the narrow and long car lamp.

In some embodiments of the present application, when the light beam irradiates the first reflection portion 11 through the light incident surface 13, an included angle is formed between the light incident surface 13 and the light incident surface 13, for example, the light beam irradiates the first reflection portion 11 through the light incident surface 13 in a perpendicular manner.

Further, as shown in fig. 7, the light incident surface 13 is arranged as a plane. Meanwhile, the light incident surface 13 is disposed at the bottom of the first reflection portion 11, and the light incident surface 13 is disposed as a plane, so that the height of the optical element 1 is not increased, that is, the size of the optical element 1 in the vertical direction (Z direction) does not need to be increased, and the optical element 1 has a compact structure and a small size in the vertical direction, and can be applied to a narrow and long shape of an automobile lamp.

As shown in fig. 8 and 9, in some embodiments of the present application, the first reflective portion 11 is disposed at a side of the light emitting portion 14 and the light emitting portion 14 is disposed opposite to the second reflective portion 12.

Further, as shown in fig. 8 to 9, the light emitting portion 14 has both ends in the left-right direction (X direction) of the automobile, and the first reflection portion 11 may be provided on the side of the light emitting portion 14 such that the first reflection portion 11 is provided outside both ends of the light emitting portion 14 in the left-right direction of the automobile, that is, the first reflection portion 11 and the light emitting portion 14 do not overlap in projection in the front-rear direction (Y direction) of the automobile.

Note that, as shown in fig. 8 and 9, the arrangement of the light emitting portion 14 and the second reflection portion 12 opposite to each other only indicates the positional relationship between the light emitting portion 14 and the second reflection portion 12, and does not mean that the light emitting portion 14 and the second reflection portion 12 are arranged parallel to each other. For example, along the height direction Z of the automobile, the bottoms of the first reflection portion 11, the second reflection portion 12 and the light emergent portion 14 may be located on the same plane, and an included angle is formed between any two of the three portions, so as to fully utilize the space, and make the structure of the optical element 1 compact. Meanwhile, the first reflection portion 11, the second reflection portion 12 and the light exit portion 14 are located on the same plane, so that the size of the optical element 1 in the height direction (Z direction) of the automobile can be reduced, and the optical element 1 can be applied to a narrow and long automobile lamp shape.

On the other hand, as shown in fig. 4 to 6 or 10, the present application also provides a vehicle lamp module 2, where the vehicle lamp module 2 includes a plurality of light sources 21 and the above optical element 1.

In some embodiments of the present application, each reflection unit 111 is provided with at least one light source 21. For example, as shown in fig. 4 to 6 or 10, the lamp assembly includes a plurality of light sources 21, and the plurality of light sources 21 correspond to the plurality of reflection units 111 one by one, i.e., one light source 21 is provided for each reflection unit 111.

The vehicle lamp module 2 of the present application is provided with the above-described optical element 1, so that the vehicle lamp module 2 can be applied to an adaptive high beam illumination system. Simultaneously, the car lamp module 2 of this application has the light-emitting portion 14 that extends along second direction M, and light-emitting portion 14 is rectangular form along second direction M promptly, has better molding effect, can be applicable to the car molding trend of motion and the car lamp molding trend of narrow and long shape.

In some embodiments of the present application, the light sources 21 corresponding to different reflection units 111 are controlled independently from each other, i.e. the light sources 21 corresponding to different reflection units 111 can be controlled individually to be turned on or off, so as to be suitable for the adaptive high beam illumination system.

For example, the lamp module 2 is provided with eight light sources 21, and the first reflecting portion 11 is provided with eight reflecting units 111, i.e., one reflecting unit 111 is provided with one light source 21. When all eight light sources 21 are turned on, light is incident on each reflection unit 111, and after being reflected by all eight reflection units 111, the light is projected by the light-emitting portion 14 to form a light shape, and the light shape includes eight pixel light shape areas 30. When one light source 21 of the eight light sources 21 is turned off, the remaining seven light sources 21 can still be turned on, and since the spacing rib 112 is disposed between two adjacent reflection units 111, only the light source 21 corresponding to the reflection unit 111 can irradiate light to the reflection unit 111, at this time, no light is incident on the reflection unit 111 corresponding to the turned-off light source 21, and the finally formed light shape only includes seven pixel light shape areas 30, and the reflection unit 111 with the turned-off light source 21 cannot project light to the corresponding pixel light shape area 30. The turning on or off of the light source 21 is controlled by an Electronic Control Unit (ECU), and the vehicle computer processes data received by a sensor (such as a millimeter wave radar, a laser radar, etc.) to determine whether there are other road traffic users in the pixel light shape area 30 corresponding to the light source 21, if so, the vehicle computer turns off the light source 21 corresponding to the light source 21, and the light source 21 corresponding to the pixel light shape area 30 where there are no other road traffic users can still be turned on, so as to implement the function of the adaptive high beam illumination system.

In another aspect, the present application further provides a vehicle lamp, which includes the vehicle lamp module 2. The car lamp is suitable for a self-adaptive high beam lighting system by arranging the car lamp module 2. Meanwhile, the automobile lamp is provided with the light-emitting portion 14 extending along the second direction M, namely, the light-emitting portion 14 is long-strip-shaped along the second direction M, has a good modeling effect, and can be suitable for the modeling trend of moving automobiles and the modeling trend of automobile lamps.
