[0005] In one alternative implementation, the circuit board assembly includes: A first circuit board is disposed on one side of the first light guide section and is provided with the first light-emitting element; The second circuit board is located on one side of the second light guide section and is equipped with the second light-emitting element; The electrical connector is configured as a flexible structure and is electrically connected between the first circuit board and the second circuit board.

[0006] In one alternative embodiment, the luminaire further includes a bracket extending along the arrangement direction of the first light guide segment and the second light guide segment, at least one of the first light guide segment and the second light guide segment being connected to the bracket, and the circuit board assembly being connected to the bracket.

[0007] In one alternative embodiment, the light guide further includes a connecting segment, through which the first light guide segment and the second light guide segment are connected, and the connecting segment is configured to restrict at least a portion of the light to travel between the first light guide segment and the second light guide segment.

[0008] In one optional embodiment, the connecting section is provided with a groove, the first light guide section and the second light guide section are respectively located on both sides of the groove, the lamp further includes a bracket, the bracket is provided with a partition portion inserted into the groove for limiting at least part of the light to be transmitted between the first light guide section and the second light guide section, at least one of the first light guide section and the second light guide section is connected to the bracket, and the circuit board assembly is connected to the bracket.

[0009] In one alternative implementation, the connection segment includes: The first connecting segment and the second connecting segment are respectively connected to the first light guide segment and the second light guide segment, and one end of the first connecting segment and the second connecting segment are connected, while the other end is spaced apart, so that the groove is formed between the first connecting segment and the second connecting segment.

[0010] 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.

[0011] In one optional embodiment, the lamp further includes a lamp housing connected to the lamp shade and forming an accommodating space, wherein the circuit board assembly and the light guide are both disposed in the accommodating space, and the light guide and the circuit board assembly are both disposed on the lamp housing.

[0012] In one alternative embodiment, the first light guide segment 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-inlet portion. The second 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-inlet portion. Both the first bend and the second bend face the circuit board assembly.

[0013] In one alternative embodiment, at least a portion of the first light guide segment and the second light guide segment facing away from the sidewall of the circuit board assembly forms the light-emitting portion.

[0014] In one alternative embodiment, the first light guide segment and the second light guide segment are provided with an array of toothed structures on the sidewalls adjacent to the circuit board assembly.

For example, the on / off state of different light guide segments can be adjusted individually according to actual needs, or different colored light-emitting elements can be used to achieve differentiated color output for each light guide segment.

[0018] In addition, the ends of the two light guide segments that are close to each other are usually located in the middle of the lamp structure or in the assembly area.

Therefore, placing the light-inlet part of one of the light guide segments and its corresponding light-emitting components here can make full use of this installation space, thereby achieving a reasonable allocation and maximum utilization of the internal space.

[0019] Meanwhile, by placing one light-emitting element in the connection area of ​​the two light guide segments and the other light-emitting element at the far end of the light guide segment, this solution can achieve spatial dispersion of the light source, thereby alleviating local heat accumulation, reducing structural and electrical layout conflicts, and improving the rationality and reliability of the overall layout.

[0024] 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.

[0025] 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.

[0026] In order 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, this invention provides a lamp and a carrier.

[0027] The following is combined with Figures 1 to 6 This describes the lighting fixtures provided in the embodiments of the present invention.

[0028] Specifically, the luminaire includes a light guide 1, a circuit board assembly 3, a first light-emitting element 6, and a second light-emitting element 7.

[0029] The light guide 1 has at least two light guide segments 101, and each light guide segment 101 has a light input part 1011 and a light output part 1012. For example Figure 5 As shown, at least two light guide segments 101 include a first light guide segment 101a and a second light guide segment 101b arranged sequentially, and the light-entry portion 1011 of the first light guide segment 101a is located at one end of the first light guide segment 101a adjacent to the second light guide segment 101b, and the light-entry portion 1011 of the second light guide segment 101b is located at one end of the second light guide segment 101b away from the first light guide segment 101a.

[0030] The first light guide segment 101a and the second light guide segment 101b are both located on one side of the circuit board assembly 3. Specifically, the first light guide segment 101a and the second light guide segment 101b are both located on the same side of the circuit board assembly 3.

[0031] The first light-emitting element 6 and the second light-emitting element 7 are both disposed on the circuit board assembly 3 and are respectively disposed opposite to the light-inlet portion 1011 of the first light guide segment 101a and the light-inlet portion 1011 of the second light guide segment 101b. That is, the first light-emitting element 6 is opposite to the light-inlet portion 1011 of the first light guide segment 101a to transmit light to the first light guide segment 101a, and the second light-emitting element 7 is opposite to the light-inlet portion 1011 of the second light guide segment 101b to transmit light to the second light guide segment 101b.

[0032] The lamp provided in this embodiment, by configuring the light guide 1 to include at least two light guide segments 101, with each light guide segment 101 having a light intake portion 1011 and a light output portion 1012, and the first light-emitting element 6 and the second light-emitting element 7 respectively arranged opposite to the light intake portion 1011 of the corresponding light guide segment 101, enables independent segmental control of each light guide segment 101. For example, the on / off state of different light guide segments 101 can be adjusted individually according to actual needs, or different colored light-emitting elements can be used to achieve differentiated color output of each light guide segment 101, solving the problem of the single light output effect of traditional light guide 1 and fully meeting diverse and differentiated light output needs.

[0033] Furthermore, 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). Therefore, by arranging the light-inlet portion 1011 of one of the light guide segments 101 and its corresponding light-emitting element here, this installation space can be fully utilized, thereby achieving a reasonable allocation and maximum utilization of the internal space.

[0034] Meanwhile, by placing one light-emitting element in the connection area of ​​the two light guide segments 101 and the other light-emitting element at the far end of the light guide segment 101, this solution can achieve spatial dispersion of the light source, thereby alleviating local heat accumulation, reducing structural and electrical layout conflicts, and improving the rationality and reliability of the overall layout.

[0035] In some embodiments provided by the invention, the circuit board assembly 3 includes a first circuit board 301, a second circuit board 302, and electrical connectors.

[0036] The first circuit board 301 is located on one side of the first light guide section 101a and is provided with a first light-emitting element 6.

[0037] The second circuit board 302 is located on one side of the second light guide section 101b and is provided with a second light-emitting element 7.

[0038] The electrical connector is designed as a flexible structure and is electrically connected between the first circuit board 301 and the second circuit board 302. For example, the electrical connector can be a wire or a flexible circuit board. For example, control signal lines and power supply lines can be integrated into the electrical connector and distributed to the light-emitting elements corresponding to different light guide segments 101 as needed, thereby supporting more complex dynamic lighting modes, such as segment-by-segment lighting, brightness gradient, color switching, etc., while keeping the wiring neat.

[0039] As described above, one light-emitting element is placed in the connection area of ​​the two light guide segments 101, and the other light-emitting element is placed at the far end of the light guide segment 101. The two are not necessarily in the same plane or in a straight line direction. In this embodiment, by setting a flexible electrical connector, the first circuit board 301 and the second circuit board 302 are electrically connected. The flexibility and extensibility of the electrical connector can be used to allow the electrical connector to bypass structural obstacles in a limited space and achieve reliable electrical connection without forcibly adjusting the position of the circuit board, thereby reducing the design and assembly difficulty.

[0040] like Figure 1 and Figure 5As shown, in some embodiments provided by the present invention, the lamp further includes a bracket 2. The bracket 2 extends along the arrangement direction of the first light guide segment 101a and the second light guide segment 101b, at least one of the first light guide segment 101a and the second light guide segment 101b is connected to the bracket 2, and the circuit board assembly 3 is connected to the bracket 2. For example, the light guide segment 101a is screwed, glued, or snapped to the bracket 2. The circuit board assembly 3 is screwed, glued, or snapped to the bracket 2.

[0041] In this embodiment, the bracket 2 extends along the arrangement direction of the light guide section 101, connecting with the light guide section 101 and providing a mounting carrier for the circuit board assembly 3. This ensures that both the light guide 1 and the circuit board assembly use the bracket 2 as a positioning reference, avoiding positioning deviations caused by their respective independent mounting references. This ensures accurate alignment between the light inlet 1011 and the light outlet of the light-emitting element, preventing problems such as reduced light incident efficiency and unstable light output caused by relative positional offset.

[0042] In addition, during the assembly process, there is no need to fix the circuit board assembly and the light guide 1 separately. Instead, the bracket 2 and the circuit board assembly on it can be connected to the light guide 1 in one operation, thereby simplifying the assembly process and improving production efficiency.

[0043] like Figure 1 and Figure 5 As shown, in some embodiments provided by the present invention, the light guide 1 further includes a connecting segment 102.

[0044] The first light guide segment 101a and the second light guide segment 101b are connected by a connecting segment 102, and the connecting segment 102 is configured to restrict at least a portion of the light rays from passing between the first light guide segment 101a and the second light guide segment 101b. For example, any two adjacent light guide segments 101 are connected by the connecting segment 102, that is, the light guide segments 101 and the connecting segment 102 of the light guide 1 are arranged alternately.

[0045] 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 1-4 The on / off state of different light guide segments 101 can be adjusted individually according to actual needs, or different colored light-emitting components can be used to achieve differentiated color output of each light guide segment 101, which solves the problem of the single light output effect of traditional light guide components 1 and fully meets the diverse and differentiated light output needs.

[0046] 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.

[0047] 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.

[0048] 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 LEDs, 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 used and lowers hardware costs, but also eliminates the need for individual control of multiple LEDs, simplifying the control logic, reducing control difficulty, and making it easier to operate and maintain in practical applications.

[0049] 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.

[0050] like Figure 1 and Figure 5 As shown, in some embodiments provided by the present invention, the connecting section 102 is provided with a groove, and the first light guide section 101a and the second light guide section 101b are respectively located on both sides of the groove. The lamp also includes a bracket 2, which is provided with a partition 201 inserted into the groove to restrict at least part of the light from passing between the first light guide section 101a and the second light guide section 101b. At least one of the first light guide section 101a and the second light guide section 101b is connected to the bracket 2, and the circuit board assembly 3 is connected to the bracket 2.

[0051] 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.

[0052] Furthermore, the partition 201, inserted into the groove, can position the light guide 1. The engagement and positioning of the partition 201 and the groove limit the installation position and orientation of the light guide 1, preventing it from shifting or wobbling during assembly or use. This ensures the accurate alignment of the light-in and light-out segments 101, guaranteeing the stability of the lighting effect. In summary, the bracket 2 can not only block light between the light guide segments 101, but also position the light guide segments 101, install the light guide 1, and install the circuit board assembly 3.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] In some embodiments provided by the present invention, the connecting segment 102 includes a first connecting segment 1021 and a second connecting segment 1022.

[0057] The first connecting segment 1021 and the second connecting segment 1022 are respectively connected to the first light guide segment 101a and the second light guide segment 101b, that is, the first connecting segment 1021 is connected to the first light guide segment 101a, and the second connecting segment 1022 is connected to the second light guide segment 101b. 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. That is, the first connecting segment 1021 and the second connecting segment 1022 form a groove structure, for example, the first connecting segment 1021 and the second connecting segment 1022 form a U-shaped groove or a V-shaped groove.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] In some embodiments provided by the present invention, at least a portion of the first light guide segment 101a and the second light guide segment 101b away from the side wall of the circuit board assembly 3 forms a light emitting portion 1012.

[0065] In this embodiment, at least a portion of the first light guide segment 101a and the second light guide segment 101b away from the side wall of the circuit board assembly 3 forms a light emitting portion 1012. This maximizes 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. This makes the light emission path staggered from the circuit board assembly 3 and other structures, avoiding the internal structure from blocking the light and ensuring that the light can be emitted outward efficiently and uniformly, improving the light emission efficiency and uniformity. At the same time, it can prevent the light emission direction from pointing towards non-illuminating areas such as the circuit board, reducing light loss and stray light interference, and ensuring the overall light emission effect of the light guide 1.

[0066] like Figure 5 As shown, in some embodiments provided by the present invention, the end of the first light guide segment 101a near the connecting segment 102 is bent to form a first bent portion 1013a, and the end face of the first bent portion 1013a forms a light-entering portion 1011. The end of the second light guide segment 101b away from the connecting segment 102 is bent to form a second bent portion 1013b, and the end face of the second bent portion 1013b forms a light-entering portion 1011. Both the first bent portion 1013a and the second bent portion 1013b face the circuit board assembly 3; for example, the first bent portion 1013a faces the first circuit board 301, and the second bent portion 1013b faces the second circuit board 302.

[0067] In this embodiment, since the end face of the bent portion 1013 serves as the light-inlet portion 1011 and faces the light-emitting element on its corresponding circuit board, the light emitted by the light-emitting element can be incident vertically or approximately vertically onto the end face of the light guide section 101, thereby reducing reflection loss or refraction shift caused by excessive incident angle and improving light guiding efficiency.

[0068] In addition, a bending portion 1013 is provided at the end of the light guide section 101, which allows the main body of the light guide section 101 to extend along the required lighting path, while bending the light-inlet end to the area where the circuit board assembly 3 is located. This allows the bending portion 1013 to connect with the circuit board assembly 3 located on one side of the light guide section 101, enabling the light guide 1 to better adapt to complex installation environments and reduce interference with surrounding components.

[0069] In some embodiments provided by the present invention, the lamp also includes a lampshade 5.

[0070] The lampshade 5 is positioned over the outside of the light guide 1, with the light-emitting portion 1012 facing the lampshade 5. The portion of the lampshade 5 corresponding to the light-emitting portion 1012 is configured as a light-transmitting area 501, allowing light to be emitted efficiently. The portion of the lampshade 5 corresponding to the connecting section 102 is configured as a non-light-transmitting area 502, used to shield the connecting section 102 and any structural gaps or light source components that may exist, preventing stray light leakage and ensuring clear and pure light emission.

[0071] In this embodiment, by setting a light-transmitting area 501 and a non-light-transmitting area 502, corresponding to the light-emitting part 1012 and the connecting section 102 respectively, only the light-emitting part 1012 of the light guide section 101 is visible and emits light, while the connecting section 102 between adjacent light guide sections 101 is effectively hidden, thereby improving the contrast and edge sharpness of segmented on / off or color changes and enhancing the visual effect. The lampshade 5, as an external protective layer, can also prevent the light guide 1 from being damaged by dust, moisture or mechanical damage, improving the reliability of the lamp.

[0072] 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 circuit board assembly 3 and the light guide 1 are both disposed in the accommodating space, and the light guide 1 and the circuit board assembly are both disposed on the lamp housing 4. Specifically, the light guide 1 and the circuit board assembly are connected to the bracket 2 and connected to the lamp housing 4 through the bracket 2.

[0073] In this embodiment, the containment space formed by the lamp housing 4 and the lamp shade 5 can provide good physical protection and environmental isolation for the internal light guide 1 and circuit board assembly 3, so that external interference such as dust and moisture can be effectively blocked, which is conducive to extending the life of the circuit board assembly and maintaining the surface cleanliness of the light guide 1, preventing light scattering or brightness decay caused by pollution.

[0074] In addition, the light guide 1 and the circuit board assembly 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 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 introduction efficiency and light output consistency.

[0075] In some embodiments provided by the present invention, the first light guide segment 101a and the second light guide segment 101b are provided with an array of tooth-like structures 103 adjacent to the sidewall of the circuit board assembly 3. For example, the tooth-like structures 103 include, but are not limited to, serrated structures.

[0076] 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, 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Optionally, the light guide section 101 and the connecting section 102 are configured as an injection-molded integral structure.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] In some embodiments provided by the present invention, the first light-emitting element 6 or the second light-emitting element 7 is configured as a lamp bead, which may be an LED lamp.

[0087] 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 colored LED beads can be used to achieve differentiated color output of each light guide segment 101, or the fast switching response of the LED beads can be used to achieve dynamic lighting effects such as flowing light effects. 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.

[0088] Circuit board assembly 3 can organize the power supply and control circuits of the LED beads, avoid short circuits, poor contact and other faults caused by messy circuits, and improve the electrical safety of the lamp.

[0089] This invention also provides a vehicle, including but not limited to vehicles, ships, or aircraft.

[0090] Specifically, the carrier includes the light guide 1 as described above or the lamp as described above.

[0091] 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.

[0092] 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.

[0093] Optionally, refer to Figure 4 As shown, the vehicle is a vehicle with a grille. Lights are mounted on the grille. Multiple light guides 1 are arranged sequentially and at intervals along the left-right direction of the vehicle. The light guide segments 101 of the light guides 1 are also arranged sequentially along the height direction of the vehicle and extend along that direction. The left-right direction of the vehicle is its lateral direction.

[0094] 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.

[0095] 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.

[0096] 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.
