DETAILED DESCRIPTION
[0029] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0030] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0031] When there is a car coming from the opposite direction or a vehicle driving in front, adaptive driving beam (ADB) can automatically turn off the part of light that may be dazzling, to improve the safety of night driving for the driver. ADB high beam includes low resolution ADB, medium resolution ADB and high resolution ADB, low resolution ADB usually has about 20 partition illuminations, the resolution is low, about 1.3°. Medium resolution ADB usually has about 50 to 100 partition illuminations, the resolution is about 0.5°. High resolution ADB currently has about 25000 partition illuminations and million pixel design.
[0032] Although low-resolution ADB and medium-resolution ADB lamps can meet the high beam regulation requirements and do not need to additionally add high beam light compensation, the adaptive high beam lighting effect of low-resolution ADB and medium-resolution ADB lamps is not ideal, the resolution is too low to meet the user's requirements, and the high-resolution ADB with about 25000 pixels can have a better adaptive high beam lighting effect and meet the resolution requirements, but since the high-resolution ADB is mainly based on DMD to achieve high resolution, and the field of view angle of DMD is usually designed to be about ±7° due to the limitation of optical design, and the high beam regulation requires the field of view angle of high beam to be more than ±12° in the horizontal direction, so the high-resolution ADB cannot meet the regulation requirements of high beam.
[0033] Therefore, in the embodiments of the present application, a light compensation lamp assembly, a vehicle lamp system and a vehicle are provided to solve or partially solve the above problems.
[0034] Please refer to Figures 1-3 which shows a structure schematic diagram of a light compensation lamp assembly 100 provided by the embodiments of the present application, which comprises:
[0035] The first light source 1, the first lens 2 and the second lens 3 are coaxially arranged.
[0036] The first lens 2 has a first side surface 21 and a second side surface arranged oppositely, the first light source 1 is located on the first side surface 21, and the first lens 2 is used for converting the light beam emitted by the first light source 1 into a parallel light beam and emitting the parallel light beam from the second side surface.
[0037] The second lens 3 has an incident surface and an emitting surface arranged oppositely, the incident surface is attached to the second side surface, the emitting surface comprises two sub-emitting surfaces 31, the two sub-emitting surfaces 31 are symmetrical with respect to the axis of the second lens 3, and the included angle formed by the two sub-emitting surfaces 31 is less than 180 degrees, and the second lens 3 is used for diverging the light beam incident on the incident surface.
[0038] Further, the first lens is a collimating lens, and the first light source is located at the focal length position of the collimating lens, and the first lens is used for converting the light beam emitted by the first light source into a parallel light beam.
[0039] For example, please refer to Figure 2 , the first lens 2 is a plano-concave lens, one surface of the plano-concave lens is a plane, and the other surface is a concave surface, and the first light source 1 is located at the focal length position on one side of the plane, so that the plano-concave lens can collimate the light beam emitted by the first light source into a parallel light beam.
[0040] Another example is that the first lens is a double convex lens, and the first light source is located at the focal length position of the double convex lens, so that the double convex lens can collimate the light beam emitted by the first light source into a parallel light beam.
[0041] Further, the shape of the light supplement lens can be various, please refer to Figure 3 The light supplement lens can be circular from the axis of the second lens, please refer to Figures 4-5 The light supplement lens can be polygonal from the axis of the second lens. It should be noted that the shape of the light supplement lens in the axial direction can be determined according to actual needs, which is not limited here.
[0042] Please refer to Figure 6 The first light source 1 is located at the origin position, and the light beam emitted by the first light source 1 is collimated into a parallel light beam by the first lens 2 and enters the light entrance surface of the second lens 3. When the parallel light beam enters the light entrance surface of the second lens 3, it is emitted from the two sub light exit surfaces of the light exit surface, and the two sub light exit surfaces can emit the light beam. The light beam emitted from one sub light exit surface can supplement the left side of the high beam on the H1 side, and the light beam emitted from the other sub light exit surface can supplement the right side of the high beam on the H2 side. Among them, H1 represents the light exit direction of one sub light exit surface, and H2 represents the light exit direction of the other sub light exit surface.
[0043] For high-resolution ABD high beam irradiation angle not meeting the requirements of regulations, the application combines the first lens and the second lens, and the light beam of the first light source can be diverged through the two sub light exit surfaces symmetrical about the axis. Combined with the high-resolution ADB high beam, the function of supplementing the high-resolution ADB high beam can be realized.
[0044] Moreover, the light supplement lamp assembly 100 of the application has simple structure, small size and high light supplement efficiency, and can solve the problem of insufficient irradiation angle of high-resolution ADB at low cost.
[0045] It should be noted that the light supplement lamp assembly of the application can diverge the light beam emitted by the first light source in multiple directions, and can achieve the purpose of diverging in different directions by designing different curvatures of the sub light exit surface. Different diffusion angles can also be achieved by designing different curvatures of the sub light exit surface.
[0046] Further, please refer to Figure 1 Each sub light exit surface 31 has a plurality of concave surfaces 32, and each concave surface 32 is used to diverge the received parallel light beam.
[0047] It should be noted that in order to diverge the light beam into a predetermined angle range, for example, the predetermined angle range is (-7°, -12°) and (7°, 12°), the curvatures of the light exit surfaces at different positions are different, so as to ensure that the light beam is diverged into the predetermined angle range, but not in other angle ranges.
[0048] To this end, the application divides each sub light-out surface into multiple concave surfaces, each of which has a different curvature, and the closer the concave surface is to the axis of the second lens, the greater the angle of divergence and the greater the curvature.
[0049] It should be noted that the first lens and the second lens have the same refractive index, and further, the first lens and the second lens are integrated, which facilitates the production and processing of the light supplement assembly and can also reduce the installation cost of the light supplement assembly.
[0050] Further, please refer to Figures 1-5 The two sub light-out surfaces 31 are symmetrical with respect to a first plane, and the projections of the two sub light-out surfaces 31 on a second plane are V-shaped. The first plane and the second plane are perpendicular to each other and intersect the axis of the second lens 3.
[0051] Further, the two sub light-out surfaces 31 are perpendicular to the second plane.
[0052] For example, when the light supplement assembly is installed on a vehicle, the second plane is parallel to the horizontal plane, and the first lens can collimate the light beam emitted by the first light source into a parallel light beam. One sub light-out surface of the second lens can diverge the parallel light beam to the right, and the other sub light-out surface of the second lens can diverge the parallel light beam to the left, which, in combination with a high-resolution ADB lamp, can achieve the effect of supplementing light for high-resolution ADB.
[0053] It should be noted that the light supplement assembly of the application can be pre-set with different curvatures to achieve the divergence of light beams in different directions.
[0054] In one embodiment, the application further provides a vehicle lamp system 200, please refer to Figure 7 , comprising:
[0055] The light supplement assembly comprises a first light source 1, a first lens and a second lens arranged coaxially.
[0056] The first lens has oppositely arranged first and second sides, and the first light source is located on the first side. The first lens is used to convert the light beam emitted by the first light source into a parallel light beam emitted from the second side.
[0057] The second lens has oppositely arranged light-in and light-out surfaces. The light-in surface is attached to the second side, and the light-out surface comprises two sub light-out surfaces. The two sub light-out surfaces are symmetrical with respect to the axis of the second lens, and the included angle formed by the two sub light-out surfaces is less than 180 degrees. The second lens is used to diverge the light beam entering the light-in surface.
[0058] The support assembly 4 has a first mounting position for mounting the light supplement assembly.
[0059] It should be noted that the support assembly 4 is used to mount the light supplement assembly, and the light supplement assembly can disperse the light beam generated by the first light source 1.
[0060] Further, the high beam assembly includes a second light source 5 and a lens assembly for emitting the light beam emitted by the second light source 5 to form a high beam illumination area.
[0061] The support assembly 4 further includes a second mounting position for mounting the high beam assembly, and the second mounting position is on the same side of the first mounting position on the support assembly, and the maximum angle of the light beam emitted by the light supplement assembly is greater than the angle of the light beam emitted by the high beam assembly, so as to expand the high beam illumination area.
[0062] It should be noted that since the light supplement assembly and the high beam assembly are mounted on the same side of the support assembly, the light beam emitted by the light supplement assembly and the light beam emitted by the high beam assembly have the same direction, and the high beam assembly is used to emit high beam, please refer to Figure 8 , the abscissa represents the horizontal distance of the light supplement illumination area with the center line of the vehicle as the origin, which shows that the light beam emitted by the light supplement assembly forms a left light supplement illumination area 6 and a right light supplement illumination area 7, please refer to Figure 9 , the abscissa represents the horizontal distance of the light supplement illumination area with the center line of the vehicle as the origin, which shows that the light beam emitted by the high beam and the light beam emitted by the light supplement form a high beam illumination area 8, that is, the light supplement of the high beam illumination area is realized, which can meet the requirements of the high beam regulation.
[0063] The optical system of the vehicle lamp system has a small volume, and the size is about 15mmx15mmx15mm, which can be integrated with a digital light processing (DLP) or a high-resolution ADB headlamp. The light supplement efficiency is as high as 90%, and the power consumption is low and the cost is low. It can well compensate the left and right high-resolution ADB lamps.
[0064] Further, the power module is connected with the first light source and the second light source. The power module is used to provide power for the first light source and the second light source.
[0065] The application further provides a vehicle, which includes a vehicle body, a third mounting position arranged in the vehicle body, and the vehicle lamp system fixed on the third mounting position.
[0066] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art will understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
