Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and in particular to a through light and a vehicle. Background Technology

[0002] Besides their regulatory functions, automotive exterior lights are also an important element of aesthetic design. With the development of new energy technologies, more and more car manufacturers are inclined to use multi-functional continuous light designs in their headlights. Multi-functional continuous lights refer to a section of the continuous light that can perform at least two signal light functions.

[0003] In related technologies, the light from both the reused and non-reuse areas of a through-light is guided by the same optically designed light guide, such as a thick-walled component or a reflector. Because there is no need to design separate structures for the light guides in the reused and non-reuse areas, the design and manufacturing of through-lights are simple and cost-effective.

[0004] However, within the reused area, multiple light sources with different functions are arranged side-by-side to achieve different goals. This arrangement causes the light-emitting center of the light source to deviate from the optical center of the corresponding area of ​​the light guide. Thus, with the center of the non-reuse area as the boundary, the emitted light patterns on the left and right sides of the through-lamp will deviate significantly in the left-right direction. Furthermore, since the through-lamp is arranged in a mirror image on the left and right sides of the vehicle body, the deviation direction of the light pattern on the left side is also mirrored that on the right side. For example, if the light pattern on the left side of the through-lamp deviates to the right, the light pattern on the right side will deviate to the left.

[0005] Therefore, when the light source in the non-reuse area is lit together with the light source of the same type in the reuse area, the brightness of the left side of the through light will be significantly different from that of the right side when viewed from the side of the vehicle, such as the left or right side. This seriously damages the overall texture and premium feel of the through light, and thus affects the user experience. Utility Model Content

[0006] This application provides a through light and a vehicle, aiming to improve the problem of inconsistent brightness when the left and right sides are lit due to the light pattern deviation of the through light.

[0007] In a first aspect, this application provides a through-light. The through-light includes: a lamp housing, the lamp housing including a non-multiplexed area and multiplexed areas disposed on both sides of the non-multiplexed area along a left-right direction; a first light source module disposed within the lamp housing and located in the multiplexed area, the first light source module including a plurality of light source groups spaced apart along the first direction; a second light source module disposed within the lamp housing and located in the non-multiplexed area, the second light source module including a plurality of first functional light sources spaced apart along the first direction; and a light guide disposed within the lamp housing and located on the light-emitting side of the first light source module and the second light source module. Each of the light source groups includes at least two light sources with different functions, which are arranged at intervals along a second direction, where the first direction is the left-right direction of the vehicle, and the second direction is perpendicular to the first direction.

[0008] This application changes the arrangement of multiple light sources in the light source group of the related technology from a left-right orientation to a front-back or up-down orientation perpendicular to the left-right orientation. In this way, the multiple light sources in each light source group can be considered as a whole, occupying the same or very close coordinate positions in the left-right direction of the vehicle, with minimal positional offset. Thus, when any light source in each light source group is lit, the light emission center of that light source has no deviation or minimal deviation relative to the optical center of the corresponding area of ​​the light guide. Similarly, in the non-multiplexed area, multiple independent first functional light sources are arranged in the left-right direction, and the light emission center of each first functional light source also has no deviation or minimal deviation relative to the optical center of the corresponding area of ​​the light guide. This significantly improves the left-right light pattern deviation between the left and right halves of the through-light, resulting in more uniform brightness of the entire through-light regardless of whether it is viewed directly, from the left, or from the right. This helps to address the problem of inconsistent brightness when the through-light is lit from the left and right sides, thereby enhancing the premium feel and texture of the through-light and improving the user experience.

[0009] In some embodiments, each of the light source groups includes a second functional light source and a third functional light source, wherein the first functional light source and the second functional light source are position light sources, and the third functional light source is a turn signal light source or a brake light source.

[0010] With this setup, when the vehicle is stationary, it presents a uniformly bright, continuous light strip, which helps to enhance the vehicle's sense of luxury and quality. When in motion, such as during braking or steering, the reused area can provide corresponding warning signals, thus improving the versatility of the continuous light function.

[0011] In some embodiments, the at least two light sources with different functions are arranged along the front-rear direction of the vehicle; The first light source module further includes a first circuit board, and the second light source module further includes a second circuit board. The surfaces of the first circuit board and the second circuit board are parallel to the height direction of the vehicle. The plurality of light source groups are disposed on the first circuit board, and the plurality of first functional light sources are disposed on the second circuit board.

[0012] This allows multiple light sources to share a first circuit board, and multiple first-function light sources to share a second circuit board. Both the first and second circuit boards can be ordinary rigid printed circuit boards, which helps to reduce the manufacturing cost of the through-light while ensuring the reliability and convenience of the electrical connection between each light source and its corresponding circuit board.

[0013] In some embodiments, the non-multiplexed area includes a first non-multiplexed area and a second non-multiplexed area symmetrically arranged, and the light guide includes a first sub-light guide located in the two multiplexed areas, a second sub-light guide located in the first non-multiplexed area, and a third sub-light guide located in the second non-multiplexed area; wherein one of the first sub-light guides is detachably connected to the second sub-light guide, and the other first sub-light guide is detachably connected to the third sub-light guide.

[0014] This design, firstly, improves the yield, quality, and consistency of light guide components. Secondly, it enhances the ease of assembly and disassembly, increasing production efficiency. Furthermore, it improves the convenience of inspection and maintenance, reducing maintenance costs.

[0015] In some embodiments, the second sub-light guide and the third sub-light guide are integrally formed structures.

[0016] This design eliminates the seam between the two, which helps to improve the visual continuity and quality of the non-reusable area of ​​the through light while ensuring ease of assembly.

[0017] In some embodiments, the second sub-light guide and the third sub-light guide are detachably connected.

[0018] This design has two advantages: First, it improves the manufacturing yield, quality, and consistency of the second and third sub-light guides. Second, it enhances the convenience of inspection and maintenance, and reduces maintenance costs.

[0019] In some embodiments, the light guide includes a plurality of reflective bowls arranged along the first direction, wherein the reflective surface of each reflective bowl is opposite to a light source group or a first functional light source. The optical structures of the reflecting surfaces of the multiple reflecting bowls are identical.

[0020] This design helps to reduce the difficulty of designing and manufacturing through lights, and lowers costs.

[0021] In some embodiments, the reflective surface of the reflective bowl is formed with a plurality of sub-reflective surfaces.

[0022] Therefore, it is beneficial to improve the uniformity and collimation of the light reflected by the light guide, as well as to improve the utilization efficiency of the light and reduce light loss.

[0023] In some embodiments, the through lamp further includes a first lens disposed on the light-emitting side of the light guide, the first lens including a first connecting portion, a second connecting portion and a light-transmitting portion located between the first connecting portion and the second connecting portion; The light-transmitting portion is opposite to the plurality of reflective bowls, and both the first connecting portion and the second connecting portion are connected to the light guide.

[0024] This configuration has several advantages. First, it helps to further improve the uniformity of the emitted light. Second, it helps to improve the reliability and accuracy of the alignment between the light guide and the first lens, which in turn helps to improve the consistency of the through-light.

[0025] In some embodiments, the through lamp further includes a second lens disposed on the side of the first lens opposite to the light guide; The lamp housing includes a first sub-housing located on the side of the second lens away from the light guide. The first sub-housing includes a light-transmitting opening extending along the first direction. The light-transmitting opening is opposite to the light-transmitting portion, and the second lens is disposed at the light-transmitting opening.

[0026] The second lens can remodulate the light, which helps to further improve the uniformity of the emitted light and the visual effect.

[0027] In some embodiments, the plurality of reflective bowls are arranged in at least two rows along the height direction of the vehicle; The through-light also includes a first lens and a second lens sequentially disposed on the light-emitting side of the light guide. The first lens includes a light-transmitting portion. There are at least two first lenses and they are arranged at intervals along the height direction of the vehicle. The light-transmitting portion of each first lens is opposite to the plurality of reflector bowls in a row. The lamp housing includes a first sub-housing located on the side of the second lens away from the light guide. The first sub-housing includes a light-transmitting opening extending in a first direction and a partition disposed in the light-transmitting opening. The partition divides the light-transmitting opening into a plurality of sub-light-transmitting openings along the height direction of the vehicle. Each sub-light-transmitting opening is opposite to a light-transmitting portion. The second lens covers the entire sub-light-transmitting aperture.

[0028] This allows the through-light to form multiple through-light strips spaced apart along the height of the vehicle. Each layer can thus form an independently controllable optical light strip, and each layer can achieve dynamic, streamlined lighting effects, thereby further enhancing the functionality and scalability of the through-light.

[0029] Secondly, embodiments of this application provide a vehicle including the through-light described in the first aspect. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] In the description of this application, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] As described in the background section, in order to reduce costs and improve manufacturing convenience, the light emitted from the light source in the reused and non-reuse areas of the penetrating lamp is guided out by the same light guide component with the same optical design, such as a thick-walled component or a reflector.

[0037] The drawback of this type of through-light is that, within the reuse area, multiple light sources with different functions are arranged side-by-side to achieve different goals. This layout causes the light-emitting center of the light source to deviate from the optical center of the corresponding area of ​​the light guide.

[0038] like Figure 1 and Figure 2 As shown, the through-light 1 in the related technology is divided into a multiplexing area 2 on the left and right sides and a non-multiplexing area 3 in the middle. The multiplexing area 2 on the left and right sides includes multiple light source groups 21, each light source group 21 including dual light sources with different functions, for example, each light source group 21 includes a first light source 21a and a second light source 21b. The non-multiplexing area 3 includes multiple single light sources, for example, multiple third light sources 31. The function of the third light source 31 is the same as one of the functions of the first light source 21a and the second light source 21b, for example, both are position light sources. The through-light 1 also includes a light guide (not shown in the figure) covering the multiplexing area 2 and the non-multiplexing area 3.

[0039] The first light source 21a and the second light source 21b of each light source group 21 are arranged in a left-right direction, which causes the light emission center of the two light sources to deviate from the optical center of the corresponding area of ​​the light guide, thereby causing the emitted light pattern to shift in the left-right direction. Taking the center of the non-multiplexed area 3 as the boundary, the through lamp 1 can be divided into a left half and a right half. Figure 3a This is a simulation diagram showing the emitted light pattern on the left side of the lamp when the light source on the left side of the penetrating lamp 1 is lit. Figure 3b This is a simulation diagram showing the emitted light pattern on the right half of the through-lamp 1 when the position lamp on the right half is lit. As can be seen from the attached diagram, both the left and right halves exhibit left-right light pattern shifts, and these shifts are mirror images of each other.

[0040] Figure 4a This is a diagram showing the overall illumination effect of the through light 1 when viewed from the front of the vehicle. Figure 4bThis is a diagram showing the overall illuminated effect of the through light 1 when viewed from the left side of the vehicle. Figure 4c The attached image shows the overall illumination effect of the continuous light 1 when viewed from the right side of the vehicle. As can be seen from the attached image, when viewed from the side, there is a significant difference in brightness between the left and right halves of the continuous light 1, which seriously undermines the premium feel and texture of the continuous light 1, and consequently affects the user experience.

[0041] Based on the above problems, this application proposes a through light and a vehicle, aiming to improve the problem of inconsistent brightness on the left and right halves of the through light caused by large light pattern deviation.

[0042] like Figures 5 to 8 As shown, in a first aspect, this application provides a through-light 10. The through-light 10 includes a lamp housing 100, a first light source module 200, a second light source module 300, and a light guide 400. The lamp housing 100 includes a non-multiplexed area 101 and multiplexed areas 102 disposed on both sides of the non-multiplexed area 101 along the left-right direction. The first light source module 200 is disposed within the lamp housing 100 and located in the multiplexed area 102. The first light source module 200 includes a plurality of light source groups 210 spaced apart along a first direction. The second light source module 300 is disposed within the lamp housing 100 and located in the non-multiplexed area 101. The second light source module 300 includes a plurality of first functional light sources 310 spaced apart along the first direction. The light guide 400 is disposed within the lamp housing 100 and located on the light-emitting side of the first light source module 200 and the second light source module 300. Each light source group 210 includes at least two light sources with different functions. The at least two light sources with different functions are spaced apart along a second direction, where the first direction is the left-right direction of the vehicle, and the second direction is perpendicular to the first direction. The first direction is referred to as the Y direction in the attached figure. It should be noted that since the left and right halves of the through lamp 10 are symmetrical, the light guide, the first light source module 200, the second light source module 300, etc. on the right half are not shown in the attached figure.

[0043] A continuous light 10 refers to a headlight assembly that runs across the front or rear of a vehicle, achieving a slender, continuous strip-like light effect. The continuous light 10 can enhance the vehicle's premium feel and quality. The two ends of the continuous light 10 can share functions.

[0044] The through-beam 10 includes a lamp housing 100, a first light source module 200, a second light source module 300, and a light guide 400. The lamp housing 100 serves as the casing for the through-beam 10, used to fix components such as the circuit board for the light source, the light guide 400, and the light-emitting lens. The lamp housing 100 is divided into a non-multiplexed area 101 and two dual-use areas 102. The non-multiplexed area 101 is the main functional area of ​​the through-beam 10, typically providing basic, unified lighting functions; for example, it can function as a standalone position light. The dual-use areas 102 are multi-functional areas of the through-beam 10, capable of simultaneously functioning as position lights and other signal lights. The lamp housing 100 can be designed to conform to the shape of the vehicle's front or rear. For example, the central non-multiplexed area 101 of the lamp housing 100 can extend linearly in the left-right direction (first direction), while the dual-use areas 102 can extend in arcs in the left-right direction. This improves the aesthetics of the through-beam 10 and its compatibility with the vehicle's shape.

[0045] Reference Figure 7 The first light source module 200 is located in the multiplexing areas 102 on both sides and serves as the light-emitting module for the multiplexing areas 102. The first light source module 200 includes multiple light source groups 210 arranged at intervals along a first direction, and each light source group 210 integrates at least two light sources with different functions. This allows for the multiplexing of functions in the multiplexing areas 102. For example, when one of the light sources with the same function in each light source group 210 is lit, the multiplexing area 102 can perform a first type of signal light function; when another light source with the same function in each light source group 210 is lit, the multiplexing area 102 can perform a second type of signal light function, and so on.

[0046] Reference Figure 7 The second light source module 300 is the light-emitting module of the non-multiplexed area 101, which includes multiple first functional light sources 310 arranged at intervals along the first direction. That is, the non-multiplexed area 101 can realize a single signal light function. For example, the first functional light source 310 is a position light source.

[0047] The light guide 400 is located on the light-emitting side of the first light source module 200 and the second light source module 300. That is, the light guide 400 covers the multiplexing area 102 and the non-multiplexing area 101, thereby guiding the light from the first light source module 200 and the second light source module 300 to the light-emitting side. The light guide 400 can be a reflector bowl or a thick-walled component. The reflector bowl uses the reflection of the reflective surface to emit light, while the thick-walled component uses refraction and total internal reflection to emit light.

[0048] Furthermore, this application features a special design for the multiple light sources in the light source group 210 of the first light source module 200. That is, as... Figure 7As shown, at least two light sources with different functions in each light source group 210 are arranged at intervals along a second direction, which is perpendicular to the left-right direction of the vehicle. For example, the second direction can be the height direction of the vehicle or the front-back direction of the vehicle.

[0049] In other words, this application changes the arrangement of multiple light sources in the light source group in the related technology from a left-right direction to a front-back or up-down direction perpendicular to the left-right direction. Thus, the multiple light sources in each light source group 210 can be considered as a whole, occupying the same or very close coordinate positions in the left-right direction of the vehicle, with minimal positional offset in the left-right direction. Therefore, when any light source in each light source group 210 is lit, the light-emitting center of that light source has no deviation or a small deviation relative to the optical center of the corresponding area of ​​the light guide. Similarly, in the non-multiplexed area 101, multiple independent first functional light sources 310 are arranged in the left-right direction, and the light-emitting center of each first functional light source 310 also has no deviation or a small deviation relative to the optical center of the corresponding area of ​​the light guide.

[0050] Thus, using the middle position of the non-multiplexed area 101 as the boundary, the left side of the through-light 10 is defined as the left half of the multiplexed area 102 and half of the non-multiplexed area 101, and the right side of the through-light 10 is defined as the right half of the multiplexed area 102 and half of the non-multiplexed area 101. Please refer to... Figure 9a and Figure 9b The light pattern deviation in the left and right directions of the light emitted from the left and right halves of the penetrating lamp 10 is significantly improved, and the light pattern deviation is extremely small and can be ignored. At this time, when the first functional light source 310 in the non-multiplexed area 101 is lit, and when a light source of the same type as the first functional light source 310 in the multiple light source groups 210 of the multiplexed area 102 is lit, such as... Figure 10a , 10b As shown in Figure 10c, the brightness of the entire through light 10 is relatively uniform regardless of whether it is viewed from the front, from the left, or from the right. This helps to improve the problem of inconsistent brightness when the through light 10 is lit from the left and right, thereby enhancing the premium feel and texture of the through light 10 and improving the user experience.

[0051] Furthermore, under the above method, the optical structure of the light guide 400 in the multiplexing area 102 and the non-multiplexing area 101 does not need to be differentiated from the optical structure of each light source group 210 and the first functional light source 310. The same optical structure can be used, which also helps to reduce the design and manufacturing difficulty of the through lamp 10 and reduce costs.

[0052] like Figure 7As shown, in some embodiments, each light source group 210 includes a second functional light source 211 and a third functional light source 212. The first functional light source 210 and the second functional light source 211 are position light sources, and the third functional light source 212 is a turn signal light source or a brake light source.

[0053] In this embodiment, each light source group 210 includes two types of light sources: a second functional light source 211 and a third functional light source 212. The first functional light source 310 and the second functional light source 211 are position light sources. Thus, when the second functional light source 211 in the first light source module 200 and the first functional light source 310 in the second light source module 300 are lit, the through-beam lamp 10 can function as a position light with uniform brightness. When the third functional light source 212 in the first light source module 200 is lit, the through-beam lamp 10 can function as a turn signal or a brake light.

[0054] With this configuration, when the vehicle is static, it presents a uniformly bright, continuous light strip, which helps to enhance the vehicle's sense of luxury and quality. When the vehicle is in motion, such as during braking or steering, the reuse zone 102 can provide corresponding warning signals, which helps to improve the versatility of the continuous light 10's functions.

[0055] like Figure 6 and Figure 7 As shown, in some embodiments, at least two light sources with different functions in each light source group 210 are arranged along the front-rear direction of the vehicle. The first light source module 200 also includes a first circuit board 220, and the second light source module 300 also includes a second circuit board 320. The surface of the first circuit board 220 and the surface of the second circuit board 320 are both perpendicular to the height direction of the vehicle. Multiple light source groups 210 are disposed on the first circuit board 220, and multiple first functional light sources 310 are disposed on the second circuit board 320.

[0056] In this embodiment, at least two light sources with different functions in each light source group 210 of the first light source module 200 are arranged along the front-rear direction of the vehicle, and the surfaces of the first circuit board 220 and the second circuit board 320 are perpendicular to the height direction of the vehicle. That is, the emitting surface of each light source group 210 and each first functional light source 310 is perpendicular to the height direction of the vehicle. Since the through-light 10 is a conformal design with an arc segment, if at least two light sources with different functions in each light source group 210 are arranged along the height direction of the vehicle, the emitting surface of the light source in each light source group 210 will be perpendicular to the front-rear direction of the vehicle. In this case, the first circuit board 220 needs to be placed vertically, that is, its surface is perpendicular to the front-rear direction of the vehicle. At this time, the first circuit board 220 also needs to be conformal, so multiple light source groups 210 cannot share a single circuit board. The circuit board needs to be divided into multiple small boards, or a flexible circuit board that can be bent according to the shape needs to be used, which leads to reduced connection reliability and higher cost.

[0057] Therefore, through the above-mentioned limitations, this embodiment allows the light sources of multiple light source groups 210 to share the first circuit board 220, and the multiple first functional light sources 310 to share the second circuit board 320. The first circuit board 220 and the second circuit board 320 can be ordinary rigid printed circuit boards, which helps to reduce the manufacturing cost of the through lamp 10 while ensuring the reliability and convenience of electrical connection between each light source and the corresponding circuit board.

[0058] like Figures 5 to 8 As shown, in some embodiments, the non-multiplexed area 101 includes a first non-multiplexed area 101a and a second non-multiplexed area 101b symmetrically arranged, and the two multiplexed areas 102 are symmetrically arranged. The light guide 400 includes a first sub-light guide 401 located in the two multiplexed areas 102, a second sub-light guide 402 located in the first non-multiplexed area 101a, and a third sub-light guide (not shown in the figure) located in the second non-multiplexed area 101b. One of the first sub-light guides 401 is detachably connected to the second sub-light guide 402, and the other first sub-light guide 401 is detachably connected to the third sub-light guide.

[0059] In this embodiment, the first non-multiplexed area 101a and the second non-multiplexed area 101b are symmetrical, and the two multiplexed areas 102 are symmetrical. Taking the first non-multiplexed area 101a located on the left side of the through-light 10 as an example, the left-side multiplexed area 102 and the first non-multiplexed area 101a together constitute the left half of the through-light 10, while the right-side multiplexed area 102 and the second non-multiplexed area 101b together constitute the right half of the through-light 10.

[0060] Furthermore, the light guide 400 is decomposed into multiple independent sub-components, such as a first sub-light guide 401, a second sub-light guide 402, and a third sub-light guide. One of the first sub-light guides 401 is detachably connected to the second sub-light guide 402, and another first sub-light guide 401 is detachably connected to the third sub-light guide. For example, the detachable connection can be achieved through various methods such as clips, screws, and positioning pins.

[0061] This design offers several advantages. First, during injection molding, smaller parts are easier to mold, reducing defects such as warping and shrinkage, thus improving the yield, quality, and consistency of the light guide 400. Second, because the through-light 10 is a conformal design, divided into multiple sub-light guides, each sub-light guide can be installed independently and sequentially, improving assembly and disassembly convenience and increasing production efficiency. Furthermore, if a sub-light guide is damaged, only the damaged part can be disassembled and replaced, further enhancing maintenance convenience and reducing maintenance costs.

[0062] In some embodiments, the second sub-light guide 402 and the third sub-light guide are integrally formed structures.

[0063] This design eliminates the seam between the two, which helps to improve the visual continuity and quality of the non-reusable area 101 of the through light 10 while ensuring ease of assembly.

[0064] In other embodiments, the second sub-light guide 402 and the third sub-light guide are detachably connected.

[0065] This design, firstly, improves the manufacturing yield, quality, and consistency of the second and third sub-light guide components 402. Secondly, it enhances the convenience of inspection and maintenance, and reduces maintenance costs.

[0066] like Figure 8 , Figure 11 , Figure 12 As shown, in some embodiments, the light guide 400 includes a plurality of reflective bowls 410 arranged along a first direction, the reflective surface 411 of each reflective bowl 410 being opposite to a light source group 210 or a first functional light source 310, and the optical structure of the reflective surface 411 of the plurality of reflective bowls 410 being the same.

[0067] In this embodiment, the light guide 400 is a reflective light guide, which includes multiple reflective bowls 410, and the reflective surface 411 of each reflective bowl 410 corresponds to a light-emitting unit (a light source group 210 or a first functional light source 310).

[0068] The optical structure of the reflective surfaces 411 of multiple reflective bowls 410 is the same, meaning that all reflective surfaces 411 have the same surface shape, geometric contour, optical parameters such as radius of curvature, focal position, microscopic optical characteristics, etc., and can be regarded as an array formation.

[0069] This design helps to reduce the design and manufacturing difficulty of the through light 10 and lower costs.

[0070] like Figure 12 As shown, in some embodiments, the reflective surface 411 of the reflective bowl 410 is formed with a plurality of sub-reflective surfaces 411a.

[0071] Multiple sub-reflective surfaces 411a can have different curvatures and surface shapes, and each sub-reflective surface 411a can perform precise directional reflection of light. This not only helps to improve the uniformity and collimation of the light reflected by the light guide 400, but also helps to improve the utilization efficiency of light and reduce light loss.

[0072] like Figure 8As shown, in some embodiments, the through lamp 10 further includes a first lens 500 disposed on the light-emitting side of the light guide 400. The first lens 500 includes a first connecting portion 510, a second connecting portion 520, and a light-transmitting portion 530 located between the first connecting portion 510 and the second connecting portion 520. The light-transmitting portion 530 is opposite to a plurality of reflector bowls 410. The first connecting portion 510 and the second connecting portion 520 are both connected to the light guide 400.

[0073] The light guide 400 reflects the emitted light from the first light source module 200 and the second light source module 300 and projects it onto the light-transmitting portion 530 of the first lens 500, allowing the light-transmitting portion 530 to modulate the reflected light a second time. The first lens 500 is connected to the light guide 400 via the first connecting portion 510 and the second connecting portion 520, ensuring accurate alignment between the light guide 400 and the first lens 500. The first lens 500 can be made of, for example, transparent plastic.

[0074] This configuration, firstly, helps to further improve the uniformity of the emitted light. Secondly, it helps to improve the reliability and accuracy of the alignment between the light guide 400 and the first lens 500, thereby improving the consistency of the through-light 10.

[0075] like Figure 8 As shown, in some embodiments, the through lamp 10 further includes a second lens 600 disposed on the side of the first lens 500 away from the light guide 400, and the lamp housing 100 includes a first sub-housing 110 located on the side of the second lens 600 away from the light guide 400. The first sub-housing 110 includes a light-transmitting opening 111 extending along a first direction. The light-transmitting opening 111 is opposite to the light-transmitting portion 530, and the second lens 600 is disposed in the light-transmitting opening 111.

[0076] The second lens 600 is the outermost optical window penetrating the lamp 10, closing the light-transmitting opening 111 of the first sub-shell 110, and together with the first sub-shell 110, forming a sealed structure. The light emitted from the first lens 500 is further projected onto the second lens 600 and transmitted through the area of ​​the second lens 600 located at the light-transmitting opening 111. The second lens 600 can remodulate the light, thereby further improving the uniformity of the emitted light and the visual effect.

[0077] Optionally, the second lens 600 can be made of dark-colored materials such as resin or glass with a certain light transmittance. On the one hand, it can absorb and scatter ambient light, improving the anti-interference ability of ambient light. On the other hand, when not lit, it blocks the internal structure of the through-light 10, enhancing the static texture of the through-light 10. Furthermore, when lit, the second lens 600 can still transmit light, forming a better lighting effect.

[0078] Optionally, the side of the first sub-shell 110 opposite to the second lens 600 is the vehicle bumper 11, that is, the through light 10 is installed on the inside of the bumper 11.

[0079] like Figure 8 , Figure 11 As shown, in some embodiments, multiple reflector bowls 410 are arranged in at least two rows along the height direction of the vehicle. At least two first lenses 500 are arranged at intervals along the height direction of the vehicle. The light-transmitting portion 530 of each first lens 500 is opposite to a row of multiple reflector bowls 410. The first sub-shell 110 also includes a separator 112 disposed at the light-transmitting opening 111. The separator 112 divides the light-transmitting opening 111 into multiple sub-light-transmitting openings 111a along the height direction of the vehicle. Each sub-light-transmitting opening 111a is opposite to a light-transmitting portion 530. A second lens 600 covers all sub-light-transmitting openings 111a. The second lens 600 can be fixedly connected to the separator 112.

[0080] In this embodiment, the light guide 400 forms an array of at least two rows of reflector bowls. Correspondingly, each row of multiple reflector bowls 410 is provided with a first light source module 200 and a second light source module 300. Thus, the reflector bowls 410 in each row reflect the emitted light from the first light source module 200 and the second light source module 300 to the light-transmitting portion 530 of the corresponding first lens 500, and then project it from the light-transmitting portion 530 to the second lens 600. Finally, the light is transmitted through the area of ​​each sub-light-transmitting aperture 111a of the second lens 600, thereby forming multiple through-light strips arranged at intervals along the height direction of the vehicle in the through-light 10. Therefore, each layer can form an independently controllable optical light strip, and each layer can achieve dynamic pipeline light effects, which is beneficial for further improving the functional diversity and scalability of the through-light 10.

[0081] It should be noted that, in Figure 8 For the sake of simplicity, only one of the first lenses 500, the first light source module 200, and the second light source module 300 are shown in the illustration.

[0082] In one specific embodiment, refer to Figure 8 The reflector bowls 410 are formed in two rows, at which point the through light 10 can form two through light strips, one above the other. Optionally, the through light strip located above can perform the functions of position light and brake light, and the through light strip located below can perform the functions of position light and turn light; or, the opposite can be true; or, it can be the multiplexing of other signal light functions with position light, which is not limited in this application.

[0083] Secondly, embodiments of this application provide a vehicle including the through light 10 described in the first aspect.

[0084] Therefore, regardless of whether viewed directly, from the left, or from the right, the brightness of the entire through-light 10 is relatively uniform. This helps to improve the issue of inconsistent brightness when the through-light 10 is lit from the left and right sides, thereby enhancing the premium feel and texture of the through-light 10 and improving the user experience. Furthermore, it also helps to reduce the design and manufacturing difficulty of the through-light 10, thus reducing costs.

[0085] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
