[0042] like Figures 1 to 6 As shown, this embodiment provides a light guide strip, which includes a light guide strip body 10, a first light-emitting part 20, and a second light-emitting part 30. The light guide strip body 10 has a light inlet 11, the first light-emitting part 20 is disposed at the end of the light guide strip body 10 away from the light inlet 11, and a plurality of second light-emitting parts 30 are disposed on the outer periphery of the first light-emitting part 20. Specifically, in this embodiment, the light inlet 11 is used to connect a light source, the first light-emitting part 20 is disposed at the end of the light guide strip body 10 away from the light inlet 11, and the second light-emitting parts 30 are disposed on the outer periphery of the first light-emitting part 20. When light enters through the light inlet 11, part of the light can be emitted through the first light-emitting part 20 to form a first light-emitting area 100, and another part is emitted through the second light-emitting part 30 to form a second light-emitting area 200. Thus, the same light guide strip can be used to illuminate different areas, meeting the light emission needs of different areas, thereby reducing the cost of the light guide strip and improving economic efficiency.
[0043] Preferably, in this embodiment, there are two second light-emitting parts 30, both of which are disposed on the outer periphery of the first light-emitting part 20, and the two second light-emitting parts 30 are arranged at an angle, so that the two second light-emitting parts 30 can illuminate and form a "V"-shaped second light-emitting area 200 to meet the light-emitting requirements of the vehicle.
[0044] Optionally, in this embodiment, the number and position of the second light-emitting section 30 can be adjusted according to different actual usage requirements, and no specific restrictions are imposed here.
[0045] Optionally, in this embodiment, the light guide strip body 10 is also provided with a snap-fit component 13 near the light inlet 11 for connecting with the light source to ensure the stability of the light guide strip installation.
[0046] Optionally, the first light-emitting part 20 in this embodiment can adopt a variety of optical textures, such as fisheye textures and striped textures, and the specific structure and processing method of the optical textures are all existing technologies, which will not be described in detail here.
[0047] Furthermore, such as Figure 1 and Figure 2 As shown, the first light-emitting part 20 includes a first light-emitting body 21 and an optical texture. The first light-emitting body 21 is disposed at the end of the light guide strip body 10 away from the light inlet 11, and the optical texture is uniformly disposed on the first light-emitting body 21. Specifically, in this embodiment, the first light-emitting body 21 and the end of the light guide strip away from the light inlet 11 are connected, thereby ensuring that the light entering through the light inlet 11 can smoothly enter the first light-emitting body 21. The optical texture is uniformly disposed on the first light-emitting body 21 to ensure that the light can be emitted through the optical texture, thereby ensuring the illumination effect of the first light-emitting area 100.
[0048] Preferably, in this embodiment, the first light-emitting body 21 and the light guide strip body 10 are integrally formed by injection molding.
[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the first light-emitting body 21 is flared, and optical texture is disposed on the inner peripheral surface of the first light-emitting body 21. Specifically, in this embodiment, this arrangement enables the light emitted through the first light-emitting part 20 to be circular, thereby ensuring the illumination effect of the first light-emitting area 100, and the optical texture can ensure uniform light emission, thereby ensuring the light emission quality and improving aesthetics.
[0050] Optionally, in other embodiments, the shape of the first light-emitting body 21 and the location of the optical texture on the first light-emitting body 21 can be specifically set according to actual use, and are not limited here.
[0051] Furthermore, such as Figures 1 to 3 As shown, the second light-emitting section 30 includes a second light-emitting body 31 and serrated light guide teeth 32. The second light-emitting body 31 is disposed at the end of the first light-emitting body 21 away from the light guide strip body 10, and the light guide teeth 32 are disposed at the end of the second light-emitting body 31 away from the first light-emitting body 21. Specifically, in this embodiment, the second light-emitting body 31 is disposed at the end of the first light-emitting body 21 away from the light guide strip body 10, which ensures that after a portion of the light entering through the light inlet 11 of the light guide strip body 10 is emitted through the first light-emitting section 20, another portion of the light can be reflected to the second light-emitting body 31 and emitted through the light guide teeth 32, thereby ensuring the illumination effect of the second light-emitting area 200. The light guide teeth 32 are disposed at the end of the second light-emitting body 31 away from the first light-emitting body 21, thereby ensuring that the light emitted through the second light-emitting section 30 is more uniform and the illumination effect is better.
[0052] Furthermore, such as Figure 2 and Figure 3 As shown, the light guide tooth 32 includes multiple light-emitting surfaces 321, with adjacent light-emitting surfaces 321 arranged at an angle. The plane containing each light-emitting surface 321 is also arranged at an angle to the plate surface of the second light-emitting body 31. Specifically, in this embodiment, the light guide tooth 32 includes multiple light-emitting surfaces 321, with adjacent light-emitting surfaces 321 arranged at an angle to form the light guide tooth 32. The plane containing each light-emitting surface 321 is also arranged at an acute or obtuse angle to the plate surface of the second light-emitting body 31, so that the second light-emitting area 200 of the second light-emitting part 30 forms an acute or obtuse angle with the plate surface of the second light-emitting body 31. This allows for adjustment of the position of the second light-emitting area 200, ensuring performance.
[0053] Optionally, in another embodiment, the light guide 32 includes a plurality of light-emitting surfaces 321, with adjacent light-emitting surfaces 321 arranged at an angle, and the plane containing each light-emitting surface 321 being perpendicular to the plate surface of the second light-emitting body 31. Specifically, this arrangement enables the second light-emitting region 200 of the second light-emitting part 30 to be perpendicular to the plate surface of the second light-emitting body 31, thereby ensuring performance.
[0054] Preferably, in this embodiment, as Figure 1 and Figure 2 As shown, several limiting blocks 40 are provided on the two opposite plates of the second light-emitting body 31, which can position and limit the light guide strip during the installation process, ensuring the installation stability of the light guide strip.
[0055] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, two second light-emitting sections 30 are provided, both of which are disposed on the outer periphery of the first light-emitting body 21, and the two second light-emitting sections 30 are arranged at an angle. Specifically, in this embodiment, the second light-emitting bodies 31 of the two second light-emitting sections 30 are integrally formed with the first light-emitting body 21 by injection molding, which can reduce production costs and ensure product consistency.
[0056] Furthermore, such as Figure 4 and Figure 5 As shown, the light guide strip body 10 is also provided with a light mixing region 12, which is located between the light inlet 11 and the first light outlet 20, and both the first light outlet 20 and the light inlet 11 are spaced apart from the light mixing region 12. Specifically, in this embodiment, the light mixing region 12 is spaced apart from the light inlet 11, so that the light rays entering through the light inlet 11 are superimposed on each other before entering the light mixing region 12, and then the light rays are fully superimposed through the light mixing region 12, thereby improving the uniformity of the emitted light and the illumination effect.
[0057] Furthermore, as shown in Figure 5, the cross-section of the light mixing region 12 is a regular polygonal structure. Specifically, in this embodiment, the cross-section of the light mixing region 12 is a regular hexagonal structure, making the light mixing region 12 as a whole a hexagonal prism. This can extend the optical path, allowing the light to mix over a sufficient distance; it can break the directional propagation of light, avoiding local light intensity concentration; and it can also control the light emission angle, ensuring that the mixed light is emitted uniformly.
[0058] In another embodiment, the cross-section of the light mixing region 12 can also be a regular pentagon, a regular heptagon, etc., without any specific limitation.
[0059] This utility model also provides an ambient light, which includes a light-emitting module and the aforementioned light guide strip. The light-emitting module and the light guide strip are connected to the light inlet 11. By incorporating the aforementioned light guide strip, this ambient light allows for the fulfillment of different lighting requirements in various areas with only one light-emitting module connected to the light inlet 11 of the light guide strip. This satisfies users' personalized needs for ambient lighting and effectively reduces production costs.
[0060] This utility model also provides a vehicle that includes the aforementioned ambient lighting. By incorporating the ambient lighting, the vehicle can illuminate different areas through the same light guide strip, thereby meeting the illumination requirements of different areas to illuminate different patterns. Furthermore, it reduces mold and development costs, thereby lowering vehicle production costs and improving economic efficiency.
[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
