Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to light guides, lighting fixtures, and carriers. Background Technology

[0002] In the lighting field, luminaires comprising light sources and light guides are widely used. Light generated by the light source enters the light guide, is transmitted through it, and then emits light to illuminate the space. Light guides, with their light transmission characteristics, are adaptable to diverse installation scenarios. However, the light emission effects of light guides in related technologies are relatively limited, making it difficult to meet diverse lighting needs. Summary of the Invention

[0003] This invention provides a light guide, a lamp, and a carrier to solve or improve the problem that the light output effect of light guides in related technologies is relatively simple and difficult to meet the needs of differentiated lighting.

[0004] In a first aspect, the present invention provides an optical guide, comprising: At least two light guide segments are arranged sequentially, and adjacent light guide segments are connected by a connecting segment; The light guide segment is provided with a light inlet and a light outlet. The light inlet is used to allow light from the light-emitting component to enter the light guide segment, and the light outlet is used to allow light from the light guide segment to exit. The connecting segment is configured to restrict at least a portion of the light from being transmitted between two adjacent light guide segments.

[0005] In one optional embodiment, the connecting segment is provided with a groove for inserting a partition, and two adjacent light guide segments are located on both sides of the groove of the connecting segment.

[0006] In one alternative implementation, the connection segment includes: The first connecting segment and the second connecting segment are respectively connected to two adjacent light guide segments and protrude from the outer sidewall of the corresponding light guide segment. One end of the first connecting segment and the second connecting segment are connected, and the other end is spaced apart, so that the groove is formed between the first connecting segment and the second connecting segment.

[0007] In one alternative implementation, the connecting segment protrudes from the outer wall of two adjacent light guide segments.

[0008] In one alternative embodiment, the light guide segment is configured as a strip-shaped structure extending along a first direction, and at least a portion of the wall surface intersecting the first direction forms a light-emitting portion.

[0009] In one optional embodiment, the light guide segment is bent at one end near the connecting segment to form a bent portion, the outer bent side of the bent portion is connected to the connecting segment, and the end face of the bent portion forms the light-inlet portion; Alternatively, the end of the light guide segment near the connecting segment faces the connecting segment and is connected to the connecting segment, and the end face of the light guide segment away from the connecting segment forms the light intake portion.

[0010] In one optional embodiment, the light guide section has an array of toothed structures on the wall surface opposite to the light emitting part.

[0011] In one optional embodiment, the light guide includes two light guide segments, with the light-incoming portion of one light guide segment located at one end of the light guide segment near the connecting segment, and the light-incoming portion of the other light guide segment located at one end of the light guide segment away from the connecting segment.

[0012] In one optional embodiment, the light guide includes two light guide segments, one of which is bent at one end near the connecting segment to form a first bend, and the end face of the first bend forms the light intake portion; the other light guide segment is bent at one end away from the connecting segment to form a second bend, and the end face of the second bend forms the light intake portion; the bending directions of the first bend and the second bend are the same.

[0013] Secondly, the present invention also provides a lamp, comprising: The light-emitting component and the light guide as described above, each of the light-incoming parts is disposed opposite to the light-emitting component.

[0014] In one alternative embodiment, the luminaire further includes a bracket that extends along the distribution direction of the light guide segments of the light guide and is connected to at least one of the light guide segments, and the light-emitting component is mounted on the bracket.

[0015] In one alternative embodiment, the connecting segment is provided with a groove, and two adjacent light guide segments of the light guide are located on both sides of the groove. The bracket is provided with a partition, which is inserted into the groove to restrict at least a portion of the light from being transmitted between two adjacent light guide segments.

[0016] In one optional embodiment, the light guide includes two light guide segments, with the light-inlet portion of one light guide segment located at one end of the light guide segment near the connecting segment, and the light-inlet portion of the other light guide segment located at one end of the light guide segment away from the connecting segment. The light-emitting components are correspondingly disposed at the positions of the respective light-inlet portions, and all the light-emitting components are mounted on the bracket and electrically connected to each other.

[0017] In one optional embodiment, the lamp further includes a lampshade, which covers the outside of the light guide, with the light-emitting part facing the lampshade. The portion of the lampshade corresponding to the light-emitting part is configured as a light-transmitting area, and the portion of the lampshade corresponding to the connecting section is configured as a non-light-transmitting area.

[0018] In one optional embodiment, the lamp further includes a lamp housing, which is connected to the lamp shade and forms an accommodating space. The light-emitting component and the light guide are both disposed in the accommodating space, and the light guide and the light-emitting component are both disposed on the lamp housing.

[0019] Thirdly, the present invention also provides a carrier, including the light guide as described above or the lamp as described above.

[0020] In one optional embodiment, the vehicle is a vehicle with a grille, the lamps are disposed on the grille, and there are multiple light guides, which are distributed sequentially at intervals along the left-right direction of the vehicle, and the light guide segments of the light guides are distributed sequentially along the height direction of the vehicle.

[0021] The light guide provided by this invention, by designing the light guide as a structure in which at least two light guide segments and connecting segments are alternately connected, can realize independent segmental control of each light guide segment. For example, the on / off state of different light guide segments can be adjusted separately according to actual needs, or different colored light-emitting components can be used to achieve differentiated color output of each light guide segment. This effectively solves the problem of the single light output effect of traditional light guides and fully meets the diverse and differentiated light output needs.

[0022] At the same time, the connecting section can effectively limit the light transmission between adjacent light guide sections, avoid light crosstalk, ensure that the light output state of each light guide section is not affected by other light guide sections, ensure the overall light output effect of the light guide is pure and clear, and improve the light output quality and visual effect.

[0023] On the other hand, the various light guide segments are connected by connecting segments, so that the light guide components form a stable overall structure. During installation, there is no need to position and assemble each light guide segment individually. This not only simplifies the installation process and reduces the installation difficulty, but also avoids positional deviations caused by individual installation, ensuring the installation accuracy between each light guide segment and ensuring consistent light output.

[0024] On the other hand, the design of multiple light guide segments makes the light output coverage of the light guide component wider. Compared with the traditional method of achieving large-area illumination by arranging multiple independent LEDs, this application achieves large-area light output by transmitting light through light guide segments. This not only reduces the number of light-emitting components used and lowers hardware costs, but also eliminates the need to control multiple LEDs individually, simplifying the control logic, reducing the difficulty of control, and making it easier to operate and maintain in practical applications.

[0025] In addition, if the light guide is processed by injection molding, it can be produced in one piece by one mold, without the need to design a separate mold for each light guide segment. This can reduce the number of molds used and development costs. At the same time, the one-piece molding process can also improve production efficiency and reduce the overall manufacturing cost of the product.

[0026] The lamps and carriers provided by the present invention, since they include the light guide provided by the present invention, also include all the advantages of the light guide mentioned above. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] In the lighting field, luminaires comprising light sources and light guides are widely used. Light generated by the light source enters the light guide, is transmitted through it, and then emits light to illuminate the space. Light guides, with their light transmission characteristics, are adaptable to diverse installation scenarios. However, light guides in related technologies can only be turned on and off as a whole, and cannot be controlled in segments. For example, they cannot control the on / off state or color in segments, resulting in a relatively simple light emission effect that is difficult to meet diverse lighting needs.

[0032] To address or improve the problem that the light output effect of light guides in related technologies is relatively uniform and difficult to meet the needs of differentiated lighting, this invention provides a light guide, a lamp, and a carrier.

[0033] The following is combined Figures 1 to 6 The embodiment of the present invention provides an optical guide 1.

[0034] Specifically, the light guide 1 includes a light guide segment 101 and a connecting segment 102.

[0035] The light guide segment 101 is provided in at least two, and the two light guide segments 101 are arranged sequentially. Adjacent light guide segments 101 are connected by a connecting segment 102. Optionally, adjacent light guide segments 101 are located on opposite sides of the connecting segment 102.

[0036] Each light guide segment 101 is provided with a light inlet 1011 and a light outlet 1012. The light inlet 1011 is used to allow light from the light-emitting component 3 to enter the light guide segment 101, and the light outlet 1012 is used to allow light from the light guide segment 101 to exit. The connecting segment 102 is configured to restrict at least a portion of the light from being transmitted between two adjacent light guide segments 101.

[0037] In this embodiment, by designing the light guide 1 as a structure in which at least two light guide segments 101 are alternately connected to a connecting segment 102, independent segmental control of each light guide segment 101 can be achieved. For example, referring to... Figures 2-4 As shown, the on / off state of different light guide segments 101 can be adjusted individually according to actual needs, or different colored light-emitting components 3 can be used to achieve differentiated color output of each light guide segment 101, effectively solving the problem of the single light output effect of traditional light guide components 1, and fully meeting the diverse and differentiated light output needs.

[0038] Meanwhile, the connecting section 102 can limit the light transmission between adjacent light guide sections 101, avoid light crosstalk, ensure that the light output state of each light guide section 101 is not affected by other light guide sections 101, ensure the overall light output effect of the light guide 1 is pure and clear, and improve the light output quality and visual effect.

[0039] On the other hand, adjacent light guide segments 101 are connected by connecting segments 102, so that the light guide 1 forms a stable overall structure. During installation, there is no need to position and assemble each light guide segment 101 separately. This not only simplifies the installation process and reduces the installation difficulty, but also avoids positional deviations caused by individual installation, ensuring the installation accuracy between each light guide segment 101 and ensuring consistent light output.

[0040] On the other hand, the design of multiple light guide segments 101 makes the light output coverage of the light guide 1 wider. Compared with the traditional method of achieving large-area illumination by arranging multiple independent lamp beads 302, this application achieves large-area light output by transmitting light through the light guide segment 101. This not only reduces the number of light-emitting components 3 used and lowers the hardware cost, but also eliminates the need for individual control of multiple lamp beads 302, simplifying the control logic, reducing the control difficulty, and making it easier to operate and maintain in practical applications.

[0041] In addition, if the light guide 1 is processed by injection molding, it can be produced by one-piece molding with a single mold, without the need to design a separate mold for each light guide segment 101. This can reduce the number of molds used and development costs. At the same time, the one-piece molding process can also improve production efficiency and reduce the overall manufacturing cost of the product.

[0042] refer to Figure 1 and Figure 5 As shown, in some embodiments provided by the present invention, the connecting segment 102 is provided with a groove for inserting the partition portion 201, and two adjacent light guide segments 101 are located on both sides of the groove of the connecting segment 102. Optionally, the partition portion 201 is made of an opaque or highly light-absorbing material.

[0043] In this embodiment, by providing a groove on the connecting section 102 and inserting the partition 201, the ability to block light transmission between adjacent light guide sections 101 can be effectively enhanced, further suppressing crosstalk between light guide sections 101, thereby ensuring that the light output state of each light guide section 101 is independent and does not interfere with each other, and improving the overall purity and control accuracy of light output.

[0044] Additionally, the partition 201 can be mounted on the bracket 2, which can be connected to the lamp housing 4. Therefore, the partition 201, inserted into the groove, can position the light guide 1. By fitting and limiting the partition 201 with the groove, the installation position and orientation of the light guide 1 can be limited, preventing the light guide 1 from shifting or shaking during assembly or use. This ensures the accuracy of the alignment of the light guide section 101 for light intake and output, and guarantees the stability of the lighting effect.

[0045] refer to Figure 1 and Figure 5 As shown, in some embodiments provided by the present invention, the connecting segment 102 is connected to two adjacent light guide segments 101, and the connecting segment 102 protrudes from the outer sidewall of the two adjacent light guide segments 101.

[0046] In this embodiment, the connecting segment 102 protrudes from the outer wall of the light guide segment 101, causing the connection interface between the light guide segment 101 and the connecting segment 102 to form a stepped or misaligned structure. Since the light in the light guide segment 101 mainly relies on total internal reflection for transmission, when the light propagates to the connection interface between the connecting segment 102 and the light guide segment 101, if it attempts to enter the connecting segment 102, it must undergo a significant directional deflection at the interface. However, this large deflection usually exceeds the allowable range of the critical angle of total internal reflection, causing the light to be unable to effectively enter the connecting segment 102.

[0047] Similarly, even if a small amount of stray light enters the connecting section 102, since the connection between the connecting section 102 and the light guide section 101 on the other side also has a geometric misalignment, if the light wants to enter the adjacent light guide section 101 from the connecting section 102, it must also undergo a similar degree of abrupt change in propagation direction, making it difficult for the light to enter the light guide section 101. Therefore, this step or misalignment structure constitutes a geometric barrier in the optical path, restricting the optical path connectivity between adjacent light guide sections 101.

[0048] refer to Figure 1 As shown, in some embodiments provided by the present invention, the connecting segment 102 includes a first connecting segment 1021 and a second connecting segment 1022.

[0049] The first connecting segment 1021 and the second connecting segment 1022 are respectively connected to two adjacent light guide segments 101 and protrude from the outer side wall of the corresponding light guide segment 101. One end of the first connecting segment 1021 and the second connecting segment 1022 are connected, and the other end is spaced apart to form a groove between the first connecting segment 1021 and the second connecting segment 1022.

[0050] Specifically, the ends of the first connecting segment 1021 and the second connecting segment 1022 away from the light guide segment 101 are connected, and the ends of the first connecting segment 1021 and the second connecting segment 1022 near the light guide segment 101 have a gap to form a groove. For example, the first connecting segment 1021 and the second connecting segment 1022 form a U-shaped structure, and two adjacent light guide segments 101 are located on the opposite sides of the first connecting segment 1021 and the second connecting segment 1022.

[0051] In this embodiment, the groove formed by the first connecting segment 1021 and the second connecting segment 1022 allows the partition 201 to be inserted, so that the partition 201 can be inserted into the groove to limit stray light between two adjacent light guide segments 101.

[0052] Secondly, the first connecting segment 1021 and the second connecting segment 1022 are respectively connected to the adjacent light guide segment 101 and protrude from the outer wall of the light guide segment 101. Continuing the light limiting logic of the step or misaligned structure in the previous embodiment, a barrier that hinders light transmission is formed through geometric shape to prevent light crosstalk between adjacent light guide segments 101 and ensure the stability of independent light output of each light guide segment 101.

[0053] Optionally, the connecting section 102 and the light guide section 101 are made of the same material. Since the same material has the same coefficient of thermal expansion, the deformation trend of the connecting section 102 and the light guide section 101 is synchronized under temperature change environment. They will not generate internal stress or crack or fall off due to the difference in thermal expansion and contraction, thereby improving the environmental adaptability and service life of the light guide 1.

[0054] Of course, the materials of the connecting segment 102 and the light guide segment 101 are not limited to the same. In some embodiments provided by the present invention, the connecting segment 102 is made of an opaque material. It is understood that the light guide segment 101 is made of a translucent material. Opaque materials include, but are not limited to, engineering plastics with added carbon black, black polybutylene terephthalate, or polycarbonate with added opacifiers. Translucent materials include, but are not limited to, polymethyl methacrylate, polycarbonate, polystyrene, cyclic olefin copolymers, and cyclic olefin polymers.

[0055] In this embodiment, the connecting segment 102 is made of an opaque material, which can directly block light transmission from the material itself. Of course, the use of an opaque material for the connecting segment 102 can be combined with the scheme of the connecting segment 102 protruding from the side wall of the light guide segment 101, thereby forming a dual protection of material light shielding and structural restriction, avoiding light crosstalk between adjacent light guide segments 101.

[0056] refer to Figure 1 As shown, in some embodiments provided by the present invention, the light guide segment 101 is configured as a strip structure extending along the first direction X, and at least a portion of the wall surface where the light guide segment 101 intersects with the first direction X forms a light emitting portion 1012.

[0057] In this embodiment, the light guide segment 101 adopts a strip structure and its sidewall is set as the light emitting part 1012, which can maximize the use of the extension length of the light guide segment 101 to achieve linear light emission and form a continuous and uniform illumination area. It is especially suitable for scenarios that require long strip lighting, such as ambient lighting in the interior of a vehicle or grille lights on the exterior of a vehicle.

[0058] It should be noted that linear light emission refers to the continuous and uniform light emission along the extension direction achieved by the light guide segment 101 through the strip-shaped light emitting part 1012. When the light guide 1 is applied to the grid light, the first direction X can be the height direction of the vehicle. Accordingly, the light guide segments 101 of the light guide 1 are arranged sequentially along the first direction X, and all the light guide segments 101 extend along the first direction X.

[0059] refer to Figure 1 Optionally, the light guide segment 101 on the right side may be bent at one end near the connecting segment 102 to form a bent portion 1013. The outer curved side of the bent portion 1013 is connected to the connecting segment 102, and the end face of the bent portion 1013 forms a light-entering portion 1011. Specifically, the end face of the bent portion 1013 away from the main body of the light guide segment 101 forms the light-entering portion 1011. It can be understood that the outer curved side of the bent portion 1013 refers to the side of the bent portion 1013 that bulges outward.

[0060] In this embodiment, the end of the light guide segment 101 near the connecting segment 102 is connected to the connecting segment 102 through the bending portion 1013, and the design of the outer bending side of the bending portion 1013 being connected to the connecting segment 102 can not only ensure the stability of the connection between the light guide segment 101 and the connecting segment 102, but also reasonably avoid the installation space through the bending structure, making the light guide 1 more adaptable to complex installation environments and reducing interference with surrounding components.

[0061] Meanwhile, the end face of the bent portion 1013 away from the main body of the light guide section 101 forms the light-inlet portion 1011, which allows the light-emitting component 3 to be arranged perpendicular to this end face. The light can be efficiently incident on the end face of the light guide section 101, reducing the refraction loss of light during the incident process and improving the light transmission efficiency. Furthermore, the design of the bent portion 1013 can also change the direction of light transmission, allowing the main body of the light guide section 101 to extend along a preset path. In other words, the flexible spatial arrangement can be achieved through the layout of the bent portion 1013, further expanding the adaptability of the light guide component 1 in diverse installation scenarios.

[0062] Of course, the light guide segment 101 is not limited to being connected to the connecting segment 102 via the bend 1013, for example, referring to Figure 1 Optionally, the light guide segment 101 on the left side of the middle section has one end facing the connecting segment 102 and connected to the connecting segment 102, and the end face of the light guide segment 101 facing away from the connecting segment 102 forms a light-entry part 1011.

[0063] Understandably, the adaptable design of the two connection methods allows the light guide 1 to flexibly adjust the connection form of the light guide segment 101 according to the shape and size of the actual installation space without overall structural modifications, thus broadening the application range of the light guide 1. Furthermore, regardless of the connection method used, the light-inlet section 1011 of the light guide segment 101 features an end-face design, resulting in a higher degree of fit between the end face and the light-emitting component 3. This reduces light leakage during light incidence, improves optical coupling efficiency, and, combined with the strip-shaped light-emitting section 1012, ensures that each light guide segment 101 can achieve uniform and stable linear light emission under different connection configurations.

[0064] Optionally, refer to Figure 1 As shown, one of two adjacent light guide segments 101 is connected to the connecting segment 102 via a bend 1013, and the end face of the bend 1013 forms a light-entering portion 1011. The other light guide segment has its end near the connecting segment 102 facing and connected to the connecting segment 102, and its end face away from the connecting segment 102 forms a light-entering portion 1011. For example, when there are two or more light guide segments 101, any two adjacent light guide segments 101 are connected to the connecting segment 102 in the above manner. For example, two adjacent light guide segments 101 are respectively arranged on opposite sides of the connecting segment 102.

[0065] In this embodiment, by designing two adjacent light guide segments 101 as a combination structure of "bent section 1013 connection and direct connection", and the light intake sections 1011 of the two are located at different ends, a structural basis is provided for realizing the flowing lighting effect.

[0066] For example, when the brightness of each light guide segment 101 is controlled to turn on or off or gradually change, the light will be lit up sequentially along the arrangement path of the light guide segment 101. Combined with the linear light emission characteristics of the strip light-emitting part 1012, a continuous and dynamic flowing light effect can be formed, which enhances the aesthetics and atmosphere of the lamp. It is especially suitable for scenarios that require dynamic light effects, such as interior ambient lighting and exterior grille lights of vehicles.

[0067] Meanwhile, the design of light-inlet sections 1011 at different ends allows the corresponding light-emitting components 3 to be distributed according to the layout of the light guide sections 101. This not only ensures the light incident efficiency of each light guide section 101, but also optimizes the overall space occupation of the light guide 1 and improves installation flexibility by rationally planning the installation position of the light-emitting components 3.

[0068] Of course, the connection between two adjacent light guide segments 101 is not limited to the above-described manner. For example, in other embodiments, both adjacent light guide segments 101 are connected to the connection segment 102 via a bend 1013, and the end face of the bend 1013 forms a corresponding light-entry portion 1011. For example, the two adjacent light guide segments 101 are respectively arranged on opposite sides of the connection segment 102.

[0069] In this embodiment, the two curved portions 1013 can flexibly adjust their bending angle and orientation according to the orientation of the installation space, allowing the light guide 1 to adapt to more complex spatial arrangement requirements. Furthermore, the end faces of the two curved portions 1013 serve as light-intake portions 1011, allowing the light-emitting components 3 to be concentrated in the area close to the connecting section 102, reducing the dispersion of the light-emitting components 3 and facilitating circuit organization and installation maintenance. In addition, this double-bending structure also maintains the independent light-emitting characteristics of each light guide section 101, and with segmented control, symmetrical dynamic lighting effects can be achieved, enhancing the design aesthetics of the lighting.

[0070] Similarly, the two adjacent light guide segments 101 are not limited to being connected to the connecting segment 102 in the manner described above. For example, in other embodiments, the end faces of the two adjacent light guide segments 101 away from the connecting segment 102 are each formed with a corresponding light-inlet portion 1011. For example, the two adjacent light guide segments 101 are respectively arranged on opposite sides of the connecting segment 102.

[0071] In this embodiment, the light-inlet portion 1011 of the two light guide segments 101 are located at their respective ends away from the connecting segment 102. The light-emitting component 3 can be arranged at the extended end of the light guide segment 101. This can avoid the space congestion problem caused by the concentrated installation of the light-emitting component 3, and also allow the light to be uniformly transmitted to the light-emitting portion 1012 along the extension direction after entering from the end of the light guide segment 101, thus ensuring the uniformity of the emitted light.

[0072] refer to Figure 1 As shown, in some embodiments of the present invention, the light guide section 101 has an array of toothed structures 103 arranged on its wall surface opposite to the light emitting section 1012. For example, the toothed structures 103 include, but are not limited to, serrated structures.

[0073] In this embodiment, the toothed structure 103 can change the reflection path of light inside the light guide section 101, causing the light that was originally transmitted in a straight line along the light guide section 101 to undergo diffuse reflection or multiple reflections, allowing more light to be emitted uniformly from the light emitting section 1012, effectively improving the light emission efficiency and uniformity of the light guide section 101, avoiding problems such as uneven brightness and bright and dark stripes in the light emitting section 1012, and optimizing the overall light emission effect.

[0074] It is understandable that a reflective layer, a toothed structure 103, or a light-shielding layer can be provided for the non-light-emitting part (e.g., sidewall or end face) of the light guide section 101. When a reflective layer is provided, the light rays emitted from inside the light guide section 101 toward the non-light-emitting part can be reflected back to the main body of the light guide section 101, guiding the light rays to finally be emitted from the light-emitting part 1012, avoiding brightness loss caused by light leakage from the non-light-emitting surface, and improving the overall light emission efficiency.

[0075] When the toothed structure 103 is set, diffuse reflection or directional reflection can be achieved by changing the reflection angle of light, so that the light is more evenly distributed inside the light guide section 101, avoiding uneven brightness of the light output section 1012 caused by local light concentration. At the same time, the toothed structure 103 can increase the number of reflections of light in the light guide section 101, further ensuring that the light is output from the light output section 1012.

[0076] When a light-shielding layer is set, light leakage from non-light-emitting parts can be directly blocked, avoiding interference from light leakage to the surrounding environment. At the same time, the light-shielding layer can enhance the isolation effect between adjacent light guide sections 101, and further prevent cross-lighting in conjunction with the connecting section 102.

[0077] In some embodiments provided by the present invention, the light guide segment 101 and the connecting segment 102 are configured as an integrally formed structure.

[0078] In this embodiment, the optical guide 1 has a stronger overall structure, while ensuring that the relative positions between each optical guide segment 101 and the connecting segment 102 are precisely fixed, thereby ensuring the stability and consistency of optical performance.

[0079] Optionally, the light guide section 101 and the connecting section 102 are configured as an injection-molded integral structure.

[0080] In this embodiment, injection molding allows for seamless integration of the light guide segment 101 and the connecting segment 102 using a mold. Whether it's the strip structure of the light guide segment 101, the design of the curved portion 1013, or the protrusions forming steps or grooves in the connecting segment 102, accurate shaping can be achieved through the mold, ensuring the consistency and stability of the dimensions of each structure. This effectively avoids problems such as dimensional deviations and light leakage caused by splicing after separate molding. For scenarios where the connecting segment 102 and the light guide segment 101 are made of the same material, injection molding can complete the overall processing in one go, resulting in a simple and efficient production process and significantly improving mass production efficiency.

[0081] It should be noted that when the connecting section 102 and the light guide section 101 are made of different materials, a two-color injection molding process can be used. That is, the light guide section 101 is formed using a light-transmitting material and the connecting section 102 is formed using an opaque material in the same mold. The two materials are precisely fused in the mold, which not only achieves functional zoning but also maintains structural continuity, taking into account both optical isolation effect and mechanical reliability.

[0082] Of course, in other embodiments, the light guide segment 101 and the connecting segment 102 are also configured as a welded integral molding structure, a fusion integral molding structure, an adhesive integral molding structure, or a 3D printed integral molding structure.

[0083] refer to Figures 2-5 As shown, in some embodiments provided by the present invention, the light guide 1 includes two light guide segments 101, and the light-inlet portion 1011 of one light guide segment 101 is located at one end of the light guide segment 101 near the connecting segment 102, and the light-inlet portion 1011 of the other light guide segment 101 is located at one end of the light guide segment 101 away from the connecting segment 102.

[0084] In this embodiment, the ends of the two light guide segments 101 that are close to each other usually have a relatively large installation space. Arranging the light-inlet portion 1011 of one of the light guide segments 101 and the corresponding light-emitting component 3 there can make full use of this installation space and avoid wasting space. At the same time, it is not necessary to arrange the two light-emitting components 3 together on the same side, avoiding the arrangement interference caused by the congestion of space on one side.

[0085] In addition, compared to arranging the light-inlet section 1011 at one end of the two light guide sections 101 that are far apart from each other, the two light-inlet sections 1011 in this embodiment are relatively close to each other, which can shorten the distance of the electrical connection lines between the corresponding light-emitting components 3, facilitate the rapid realization of electrical connection, reduce the amount of wiring and the complexity of the layout, and reduce the risk of wiring connection failure.

[0086] Further, refer to Figure 1 and Figure 5 As shown, the light guide 1 includes two light guide segments 101. One light guide segment 101 is bent at one end near the connecting segment to form a first bent portion 1013a, and the end face of the first bent portion 1013a forms a light-entering portion 1011. The other light guide segment 101 is bent at one end away from the connecting segment 102 to form a second bent portion 1013b, and the end face of the second bent portion 1013b forms a light-entering portion 1011. The bending directions of the first bent portion 1013a and the second bent portion 1013b are the same.

[0087] In this embodiment, the curved portions of the two light guide segments 101 are bent in the same direction, which makes it easy to arrange the light-emitting components 3 of each light guide segment 101 on the same side of the light guide 1. The light-emitting components 3 are concentrated on the same side of the light guide 1, and can be standardized by relying on a unified bracket 2. There is no need to adjust the installation reference on both sides separately. At the same time, the distance between the light-emitting components 3 is relatively close, which makes it easy to connect them by wires.

[0088] This invention also provides a lamp.

[0089] Specifically, the luminaire includes a light-emitting component 3 and a light guide 1 as described above.

[0090] Each of the light-emitting parts 1011 is arranged opposite to the corresponding light-emitting component 3.

[0091] In this embodiment, the lamp includes a light guide 1, and thus includes all the advantages of the light guide 1 mentioned above, so it will not be described in detail here.

[0092] In some embodiments provided by the present invention, the lamp also includes a bracket 2.

[0093] The bracket 2 extends along the distribution direction of the light guide segments 101 of the light guide 1 and is connected to at least one light guide segment 101. For example, the light guide segment 101 is screwed, bonded, or snapped onto the bracket 2. The light-emitting component 3 is mounted on the bracket 2, for example, the light-emitting component 3 is screwed, bonded, or snapped onto the bracket 2.

[0094] In this embodiment, the bracket 2 extends along the distribution direction of the light guide section 101, connecting with the light guide 1 and providing a mounting carrier for the light-emitting component 3. This ensures that both the light guide 1 and the light-emitting component 3 use the bracket 2 as a positioning reference, avoiding positioning deviations caused by each using an independent mounting reference. This ensures precise alignment between the light-inlet section 1011 and the light-emitting end of the light-emitting component 3, preventing problems such as reduced light incident efficiency and unstable light output caused by relative positional offset.

[0095] In addition, during the assembly process, there is no need to fix the light-emitting component 3 and the light guide 1 separately. Instead, the bracket 2 and the light-emitting component 3 on it can be connected to the light guide 1 in one operation, which greatly simplifies the assembly process and improves production efficiency.

[0096] Optionally, the light-emitting component 3 includes an LED bead 302 and a circuit board 301. The LED bead 302 is disposed on the circuit board 301 and can be an LED. The circuit board 301 is connected to the bracket 2, for example, by screwing, snapping, or gluing.

[0097] In this embodiment, the LED lamp has the characteristics of low energy consumption, fast response speed, long life and support for single-color or multi-color emission, which is highly matched with the segmented control requirements of the light guide 1. For example, different color outputs of each light guide segment 101 can be achieved by using LED beads 302 of different colors, or dynamic lighting effects such as flowing light effects can be achieved by using the fast switching response of LED beads 302. At the same time, the low energy consumption characteristic improves the energy efficiency of the lamp, and the long life advantage reduces the frequency of later maintenance.

[0098] In addition, the circuit board 301 can organize the power supply and control circuits of the lamp beads 302, avoid short circuits, poor contact and other faults caused by messy circuits, and improve the electrical safety of the lamp.

[0099] In some embodiments of the present invention, the connecting segment 102 is provided with a groove, and two adjacent light guide segments 101 of the light guide 1 are located on both sides of the groove. The bracket 2 is provided with a partition 201, which is inserted into the groove to restrict at least a portion of the light from being transmitted between two adjacent light guide segments 101. Optionally, the partition 201 is integrally formed by extending from the bracket 2 or fixed to the bracket 2.

[0100] In this embodiment, the partition 201 is inserted into the groove of the connecting section 102, which can effectively block the optical path connection between adjacent light guide sections 101, limit stray light leaking from one light guide section 101 to another light guide section 101, thereby suppressing optical crosstalk, enabling each light guide section 101 to achieve independent brightness control or color output, improving the boundary clarity and visual contrast of segmented lighting, and meeting the needs of high-precision differentiated lighting.

[0101] In addition, the partition 201 is inserted into the groove, which can constrain the position of the light guide 1 on the bracket 2. This can not only ensure the relative position stability between the light guide 1 and the bracket 2, but also prevent the light guide 1 from being displaced due to vibration, thermal expansion and contraction or external impact during use, thereby maintaining the long-term alignment accuracy between the light-inlet part 1011 and the light-emitting component 3 and ensuring the stability of optical performance.

[0102] In summary, the partition 201, located on the bracket 2, combines the light-shielding function with the installation structure. Specifically, while supporting the light guide 1 and the light-emitting component 3, the bracket 2 reinforces the connecting section 102 through the partition 201, eliminating the need for additional independent light-shielding components. This simplifies the overall structure of the lamp and reduces the number of parts and assembly costs.

[0103] In some embodiments provided by the present invention, the light guide 1 includes two light guide segments 101, and the light-inlet portion 1011 of one light guide segment 101 is located at one end of the light guide segment 101 near the connecting segment 102, and the light-inlet portion 1011 of the other light guide segment 101 is located at one end of the light guide segment 101 away from the connecting segment 102.

[0104] Accordingly, the light-emitting components 3 are respectively disposed at the corresponding positions of the light-inlet sections 1011. For example, the number of light-emitting components 3 and light guide sections 101 are the same and correspond one-to-one. The light-emitting components 3 are all mounted on the bracket 2 and are electrically connected to each other.

[0105] In this embodiment, the ends of the two light guide segments 101 that are close to each other are usually located in the middle of the lamp structure or in the assembly concentration area. This position often has relatively ample installation space because it avoids the limitations of the end housing or interference with other functional modules (such as clips). By arranging the light-inlet portion 1011 of one of the light guide segments 101 and its corresponding light-emitting component 3 here, this installation space can be fully utilized, thereby achieving a reasonable allocation and maximum utilization of the internal space.

[0106] Meanwhile, by placing one light-emitting component 3 in the central connection area and another in the far end, this solution can achieve spatial dispersion of the light source, which not only alleviates local heat accumulation but also reduces structural and electrical layout conflicts, thereby improving the rationality and reliability of the overall layout.

[0107] Optionally, the circuit boards 301 of the two light-emitting components 3 are electrically connected by wires.

[0108] In this embodiment, one light-emitting component 3 is arranged near the middle region of the connecting section 102, and the other is located at the far end of the light guide section 101. The two are not necessarily in the same plane or in a straight line direction. The wire has good flexibility and ductility, and can bypass structural obstacles in a limited space to achieve reliable electrical connection without forcibly adjusting the position of the circuit board 301.

[0109] In addition, the two light-emitting components 3 can each be mounted on an independent circuit board 301, with their size and shape optimized according to local space and heat dissipation conditions, and then interconnected by wires to form a unified power supply or control circuit.

[0110] In some embodiments provided by the present invention, the lamp also includes a lampshade 5.

[0111] The lampshade 5 is placed on the outside of the light guide 1, and the light emitting part 1012 faces the lampshade 5. The part of the lampshade 5 corresponding to the light emitting part 1012 is set as a light-transmitting area 501, which allows light to be emitted efficiently. The part of the lampshade 5 corresponding to the connecting section 102 is set as a non-light-transmitting area 502, which is used to shield the connecting section 102 and any structural gaps or light source components that may exist, to prevent stray light leakage and ensure the clarity and purity of the light output effect.

[0112] In this embodiment, by precisely corresponding the light-transmitting area 501 and the non-light-transmitting area 502, only the light-emitting portion 1012 of the light guide segment 101 is visible and emits light, while the connecting segment 102 between adjacent light guide segments 101 is effectively hidden. This improves the contrast and edge sharpness of segmented on / off states or color changes, enhancing visual expressiveness. The lampshade 5, as an external protective layer, prevents the light guide component 1 from being damaged by dust, moisture, or mechanical force, improving the reliability of the lamp.

[0113] In some embodiments provided by the present invention, the lamp further includes a lamp housing 4. The lamp housing 4 is connected to the lamp shade 5 and forms an accommodating space. The light-emitting component 3 and the light guide 1 are both disposed in the accommodating space, and the light guide 1 and the light-emitting component 3 are both disposed on the lamp housing 4. Specifically, the light guide 1 and the light-emitting component 3 are connected to the bracket 2 and connected to the lamp housing 4 through the bracket 2.

[0114] In this embodiment, the containment space formed by the lamp housing 4 and the lamp shade 5 provides good physical protection and environmental isolation for the internal light guide 1 and the light-emitting component 3, effectively blocking external interference such as dust and moisture, which helps to extend the life of the light-emitting component 3 and maintain the surface cleanliness of the light guide 1, preventing light scattering or brightness decay caused by pollution.

[0115] In addition, the light guide 1 and the light-emitting component 3 have been pre-aligned and fixed on the bracket 2, and their relative positions are maintained as a whole when the lamp housing 4 is installed later. This ensures that the coupling accuracy between the light-inlet part 1011 and the light-emitting surface is not affected by the manufacturing tolerance or assembly deviation of the lamp housing 4, effectively improving the light-inlet efficiency and light-out consistency.

[0116] This invention also provides a vehicle, including but not limited to vehicles, ships, or aircraft.

[0117] Specifically, the carrier includes the light guide 1 as described above or the lamp as described above.

[0118] It should be noted that the vehicle includes light guide 1 or lamps, and therefore also includes the corresponding advantages, so this will not be elaborated further.

[0119] Optionally, the vehicle is a vehicle, and the interior trim of the vehicle is equipped with the lamps, or the front grille of the vehicle is equipped with the lamps.

[0120] Optionally, refer to Figure 4 As shown, the vehicle is a vehicle with a grille. Lights are mounted on the grille, and multiple light guides 1 are arranged at intervals along the left-right direction of the vehicle. The light guide segments 101 of the light guides 1 are arranged sequentially along the height direction of the vehicle. The left-right direction of the vehicle is its lateral direction.

[0121] In this embodiment, multiple light guides 1 are arranged at intervals along the lateral side of the vehicle, which can flexibly fit the lateral extension structure of the grille to form a segmented light-emitting strip, effectively enhancing the visual width and technological feel of the front of the vehicle.

[0122] Furthermore, the light guide segments 101 of each light guide 1 are distributed along the vehicle height direction, which can make full use of the installation space of the grille in the vehicle height direction and achieve different light output effects. For example, lighting up each light guide segment 101 from top to bottom can achieve a flowing water effect, or different light guide segments 101 can output light of different colors.

[0123] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
