Description

Technical Field

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

[0002] Currently, many car designs integrate the functions of multiple lights into a single light outlet. This necessitates a highly integrated and compact structure to achieve these functions. Furthermore, as people's demands for car aesthetics increase, so do their requirements for the lighting performance of each light function. Existing technologies often use a composite solution with two different light sources within a single condenser. However, both light sources need to be offset from the condenser's focal point, resulting in defocusing, which affects the lighting effect and reduces luminous efficiency.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art by providing a light guide component and a vehicle lamp.

[0005] According to one aspect of this application, a light guiding component is provided, including a first light-concentrating part, a second light-concentrating part, and a main body part. The first light-concentrating part and the second light-concentrating part are respectively adapted to different light sources. The main body part has a first reflective surface and a first light-emitting surface disposed opposite to each other. The first reflective surface is disposed in the light-emitting direction of the first light-concentrating part, and the first light-emitting surface is disposed in the light-emitting direction of the first reflective surface. The main body part is provided with a plurality of isolation structures. The plurality of isolation structures are disposed on the reflected light path from the first reflective surface to the first light-emitting surface, and the plurality of isolation structures are arranged at intervals to form a light guiding channel between adjacent isolation structures. The side of each isolation structure facing the first light-emitting surface has a second reflective surface. The second reflective surface is disposed in the light-emitting direction of the second light-concentrating part, and the first light-emitting surface is disposed in the light-emitting direction of the second reflective surface.

[0006] In one embodiment, the first light-concentrating part and the second light-concentrating part are disposed on the same side of the main body in a first direction, which is perpendicular to the main light-emitting direction of the light guide component.

[0007] In one embodiment, the second light-concentrating portion is spaced apart on one side of the main body portion in a first direction, the first direction being perpendicular to the main light-emitting direction of the light guide component; the side of the second light-concentrating portion facing the main body portion has a second light-emitting surface, and the portion of the main body portion opposite to the second light-emitting surface has a second light-incident surface, both the second light-emitting surface and the second light-incident surface being provided with diffusion patterns.

[0008] In one embodiment, the second reflective surface is a curved surface that is concave towards the first reflective surface.

[0009] In one embodiment, the main body further has a peripheral wall, which is connected between the first reflective surface and the first light-emitting surface, and the peripheral wall surrounds the periphery of the first reflective surface and the first light-emitting surface; the isolation structure is an isolation hole, and at least one end of the isolation hole penetrates through the peripheral wall.

[0010] In one embodiment, the second light-concentrating part is disposed on one side of the main body in the first direction, and the isolation hole penetrates the opposite wall surface of the peripheral wall along the second direction. The first direction, the second direction, and the main light-emitting direction of the light guide component are perpendicular to each other. The isolation holes are spaced apart along the first direction and spaced apart along the main light-emitting direction of the light guide component.

[0011] In one embodiment, the second light-concentrating part is disposed on one side of the main body in the first direction, and the isolation hole penetrates the opposite wall surface of the peripheral wall along the second direction. The first direction, the second direction and the main light-emitting direction of the light guide component are perpendicular to each other. A projection surface λ is set perpendicular to the first direction.

[0012] In one embodiment, the cross-section of the isolation hole is triangular or fan-shaped.

[0013] In one embodiment, the first reflective surface is provided with a diffusion pattern.

[0014] According to another aspect of this application, a vehicle lamp is provided, including any of the aforementioned light guide components and the vehicle lamp itself.

[0015] The beneficial effects of this application are as follows: by setting the first and second focusing parts, the light emitted from different light sources can be processed separately, avoiding the simultaneous correspondence of two different light sources to the same focusing part. This ensures that each light source is arranged at the focal point of the focusing part, reducing light divergence and improving the lighting effect and light efficiency.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The light guide component and vehicle lamp in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In existing technologies, two different light sources are often placed in a single condenser to form a composite solution. Both light sources need to be defocused from the focal point of the condenser, resulting in defocusing, which affects the lighting effect and reduces the light efficiency.

[0034] To address the aforementioned technical problems, this application provides a light guiding component, including a first focusing portion, a second focusing portion, and a main body. The first focusing portion and the second focusing portion are adapted to different light sources. The main body has a first reflective surface and a first light-emitting surface disposed opposite to each other. The first reflective surface is disposed in the light-emitting direction of the first focusing portion, and the first light-emitting surface is disposed in the light-emitting direction of the first reflective surface. The main body is provided with multiple isolation structures, which are disposed on the reflected light path from the first reflective surface to the first light-emitting surface. The multiple isolation structures are arranged at intervals to form a light guiding channel between adjacent isolation structures. Each isolation structure has a second reflective surface on the side facing the first light-emitting surface. The second reflective surface is disposed in the light-emitting direction of the second focusing portion, and the first light-emitting surface is disposed in the light-emitting direction of the second reflective surface. This will be described in detail below.

[0035] See Figure 1-3The light guide component 10 includes a first light-concentrating part 11, a second light-concentrating part 12, and a main body 13. The first light-concentrating part 11 and the second light-concentrating part 12 are adapted to different light sources. The main body 13 has a first reflective surface 131 and a first light-emitting surface 132 arranged opposite to each other. The first reflective surface 131 is arranged in the light-emitting direction of the first light-concentrating part 11, and the first light-emitting surface 132 is arranged in the light-emitting direction of the first reflective surface 131. The main body 13 is provided with a plurality of isolation structures 20. The plurality of isolation structures 20 are arranged on the reflected light path from the first reflective surface 131 to the first light-emitting surface 132, and the plurality of isolation structures 20 are arranged at intervals to form a light guide channel 30 between adjacent isolation structures 20. The side of the isolation structure 20 facing the first light-emitting surface 132 has a second reflective surface 21. The second reflective surface 21 is arranged in the light-emitting direction of the second light-concentrating part 12, and the first light-emitting surface 132 is arranged in the light-emitting direction of the second reflective surface 21.

[0036] The first focusing section 11 and the second focusing section 12 are used to converge the light emitted by the light source, avoiding excessive light dispersion, improving light utilization, and thus enhancing the final lighting brightness. For ease of explanation, in the following embodiments, the first focusing section 11 and the second focusing section 12 can be configured to collimate the light emitted by the light source, so that the light is directed parallel to the first reflecting surface 131 and the second reflecting surface 21, which is beneficial to improving the lighting effect. In some embodiments, other focusing methods can also be used, not limited to these. For ease of explanation, the light collimated by the first focusing section 11 is referred to as the first light source 40, and the light collimated by the second focusing section 12 is referred to as the second light source 50.

[0037] By setting the first focusing part 11 and the second focusing part 12, the light emitted from different light sources (first light source 40 and second light source 50) can be processed separately, avoiding the simultaneous correspondence of two different light sources to the same focusing part. When a single focusing part corresponds to two light sources, in order to ensure the final lighting effect of the two light sources (the closer the light source is to the focal point of the focusing part, the better the lighting effect), both light sources need to be deviated from the focal point of the focusing part. Both light sources are far from the focal point of the focusing part, resulting in defocusing and reducing the lighting effect and light efficiency. In this application, one focusing part corresponds to one light source, which can ensure that each light source is arranged at the focal point of the focusing part, reducing light divergence and improving the lighting effect and light efficiency. Moreover, one focusing part corresponds to one light source, which is conducive to improving heat dissipation efficiency and avoiding mutual thermal influence between different light sources, thus affecting the light efficiency.

[0038] Meanwhile, one focusing part corresponds to one light source. When the light source is set as an LED bead (in some embodiments, the light source can also be other forms of setting, not limited to this), there is no need to use small-sized LED beads (when one focusing part corresponds to two light source LED beads, in order to reduce the distance between the LED bead and the focal point of the focusing part, small-sized LED beads can be selected), and using large-sized LED beads reduces production costs.

[0039] The light emitted from the first light source 40 is collimated by the first focusing part 11 and then shines on the first reflecting surface 131. After being reflected by the first reflecting surface 131, it shines on the first light emitting surface 132. During the process of the light shining from the first reflecting surface 131 to the first light emitting surface 132, it passes through the light guide channel 30 and the spaced isolation structure 20, which provides space for the propagation of the light and does not affect the final lighting effect. In addition, the light emitted from the second light source 50 shines directly on the first light emitting surface 132 after passing through the second reflecting surface 21. The light emitted by the two light sources (the first light source 40 and the second light source 50) ultimately shines on the first light emitting surface 132. Different light sources can be lit according to actual usage needs, which improves the versatility of the light guide component 10. The two focusing parts (the first focusing part 11 and the second focusing part 12) share a main body 13, which helps to reduce space occupation and facilitates the lightweight and flat design of the headlight. In addition, they share a light emitting surface (the first light emitting surface 132), which improves the appearance.

[0040] It should be noted that the two light sources can have the same configuration, or in some embodiments, different brightness and color settings, depending on the actual usage requirements. Furthermore, the first reflective surface 131 is positioned in the light-emitting direction of the first focusing section 11, meaning the first reflective surface 131 is configured to receive the light converged by the first focusing section 11. The arrangement of the first light-emitting surface 132 and the second reflective surface 21 in the light-emitting direction is similar, serving to receive the relevant light, and will not be elaborated further here.

[0041] It is worth mentioning that the different lighting effects of the two light sources (such as different brightness) can be achieved by adjusting the size, shape, and spacing between adjacent isolation structures 20, thus meeting different functional requirements. For example, if the spacing between adjacent isolation structures 20 is reduced, that is, the size of the light guide channel 30 is reduced, the luminous flux of the light emitted from the first reflecting surface 131 to the first light emitting surface 132 is reduced, resulting in a decrease in brightness. Conversely, the brightness is increased. This will not be elaborated further here, but relevant adjustments can be made according to actual usage requirements.

[0042] In some embodiments, the first light-concentrating part 11 and the second light-concentrating part 12 are disposed on the same side of the main body part 13 in a first direction, which is perpendicular to the main light-emitting direction of the light guide member 10.

[0043] The first focusing part 11 and the second focusing part 12 are disposed on the same side of the main body 13, that is, by utilizing the longitudinal direction of one focusing part ( Figure 2 Another focusing section is set in the viewing angle space; compared to the two focusing sections being set in the first direction of the main body 13 respectively (viewing angle) Figure 1-6The different sides of the light guide component 10 (as shown in the Z direction below) are arranged in this way to reduce the overall volume occupied by the light guide component 10 in the first direction, which is conducive to the overall flat design of the light guide component 10, can meet the personalized design requirements of the vehicle, and is also conducive to the arrangement of other components inside the headlight.

[0044] In some embodiments, the first focusing part 11 and the second focusing part 12 may also be disposed on different sides of the main body 13. This arrangement allows the first light source 40 and the second light source 50 to be staggered, providing sufficient installation space for the installation of the two light sources and improving installation efficiency. The design is carried out according to the actual shape requirements.

[0045] It should be noted that the first direction is any direction perpendicular to the main light-emitting direction of the light guide component 10, and the main light-emitting direction of the light guide component 10 is as follows: Figure 1-6 The direction is shown as X.

[0046] In some embodiments, the second light-concentrating portion 12 is spaced apart on one side of the main body portion 13 in a first direction, the first direction being perpendicular to the main light-emitting direction of the light guide component 10; the side of the second light-concentrating portion 12 facing the main body portion 13 has a second light-emitting surface 121, and the portion of the main body portion 13 opposite to the second light-emitting surface 121 has a second light-incident surface 133, and both the second light-emitting surface 121 and the second light-incident surface 133 are provided with diffusion patterns.

[0047] By spaced apart from the main body 13, the second light-emitting surface 121 and the second light-incident surface 133 are added. The diffusion pattern is set on the second light-emitting surface 121 and the second light-incident surface 133, which can diffuse the passing light, which helps to improve the uniformity of the final light guide component 10 lighting and improve the lighting effect.

[0048] Furthermore, by providing the second light-emitting surface 121 and the second light-incident surface 133, the lateral movement of the main body 13 can be reduced. Figure 2 The larger the lateral dimension of the main body 13 (viewing angle), the greater the distance the light travels inside the main body 13. The greater the propagation distance, the more uniformly the first light-emitting surface 132 is illuminated. In this embodiment, two diffusion surfaces (the second light-emitting surface 121 and the second light-incident surface 133) are formed by the second light-concentrating part 12 and the main body 13 at intervals, which improves the uniformity of light. Correspondingly, reducing the lateral dimension of the main body 13 will not affect the uniformity of the final illumination of the light guide component 10. On the contrary, it reduces the lateral space occupied by the light guide component 10, which is beneficial to the arrangement of other components inside the headlight.

[0049] It is worth mentioning that the second focusing part 12 and the main body part 13 are spaced apart, that is, the second focusing part 12 and the main body part 13 are separately arranged. During production and processing, the second focusing part 12 and the main body part 13 can be processed separately, which improves processing efficiency. Moreover, in subsequent maintenance and repair, only the corresponding part (the second focusing part 12 or the main body part 13) needs to be replaced, instead of replacing the whole part, which reduces the cost of use.

[0050] In some embodiments, the first focusing part 11 may also be spaced apart from the main body part 13, and the design may be made accordingly based on the actual lighting requirements.

[0051] In some embodiments, the second reflective surface 21 is a curved surface that is recessed toward the first reflective surface 131.

[0052] By making the second reflective surface 21 curved, the light incident on the second reflective surface 21 can be diffused and emitted toward the first light-emitting surface 132, which helps to improve the uniformity of the final light guide component 10 lighting and improve the lighting effect.

[0053] It should be noted that in this embodiment, the second reflective surface 21 has a total internal reflection effect, which can reflect most of the light incident on the second radiating surface to the first light emitting surface 132, which is beneficial to improving the lighting brightness of the light guide component 10. In some embodiments, the second reflective surface 21 may not be a total internal reflection surface, and the design is based on the actual lighting brightness required by the light guide component 10, and is not limited to this.

[0054] In some embodiments, the main body 13 further has a peripheral wall 134, which is connected between the first reflective surface 131 and the first light-emitting surface 132, and the peripheral wall 134 surrounds the periphery of the first reflective surface 131 and the first light-emitting surface 132; the isolation structure 20 is an isolation hole 60, at least one end of which penetrates the peripheral wall 134.

[0055] In this embodiment, the isolation structure 20 is an isolation hole 60, and at least one end of the isolation hole 60 penetrates the peripheral wall 134 (the isolation hole 60 can be a blind hole and / or a through hole, and the design is carried out according to the actual use requirements). One end of the isolation hole 60 penetrates the surface (peripheral wall 134) of the main body 13. This setting facilitates processing and can reduce processing costs.

[0056] It should be noted that in the above embodiments, the isolation structure 20 is a hollow structure, and the second reflective surface 21 is the hole wall of the isolation hole 60 facing the first light-emitting surface 132; in some embodiments, the isolation hole 60 can also be filled with a related medium or other design (for example, the isolation structure 20 is a solid part that is inserted into the main body 13). The refractive index of the medium is lower than that of the main body 13, which can ensure that the light incident on the second reflective surface 21 is reflected and directed toward the first light-emitting surface 132.

[0057] It is worth mentioning that, in some embodiments, the isolation hole 60 may also be an internal hole disposed inside the main body 13 (e.g., Figure 5 As shown), that is, neither end of the isolation hole 60 penetrates the peripheral wall 134 of the main body 13 (that is, both ends of the isolation hole 60 are closed, for example, a through hole can be processed first, and then the two ends of the through hole can be sealed to achieve the inner hole shape), and it is not limited to this.

[0058] In some embodiments, the second light-concentrating part 12 is disposed on one side of the main body part 13 in the first direction, and the isolation hole 60 penetrates the opposite wall surface of the peripheral wall 134 along the second direction. The first direction, the second direction and the main light-emitting direction of the light guide component 10 are perpendicular to each other. The isolation holes 60 are spaced apart along the first direction and spaced apart along the main light-emitting direction of the light guide component 10.

[0059] In this embodiment, the isolation hole 60 is along the second direction (e.g., Figure 1 as well as Figure 4-6 As shown in the Y direction, the isolation hole 60 penetrates the wall opposite to the peripheral wall 134, which is a through hole, which facilitates processing and improves processing efficiency. In addition, the isolation hole 60 is a through hole, which means that the second reflective surface 21 corresponding to each isolation hole 60 has a larger size in the second direction (compared to the isolation hole 60 not penetrating the peripheral wall 134), which can receive more light from the second light-concentrating part 12, which is beneficial to improving the lighting brightness of the light guide component 10.

[0060] The isolation holes 60 are spaced apart along the first direction and also spaced apart along the main light-emitting direction of the light guide component 10, that is, in Figure 2 From a visual perspective, the isolation holes 60 are spaced apart in both the vertical and horizontal directions, that is, the isolation holes 60 are... Figure 2 Arranged in a tilted manner from the perspective of each other.

[0061] The isolation holes 60 are spaced apart in the vertical direction to form a light guide channel 30, providing a propagation space for the light reflected by the first reflective surface 131; the isolation holes 60 are spaced apart in the horizontal direction, which can cover the light output range of the second light-concentrating part 12 with fewer isolation holes 60, which is beneficial to reduce the size of the main body 13 in the vertical direction and reduce space occupation.

[0062] Specifically, the horizontal dimension of the second focusing section 12 is fixed (the dimension of the light emission range in the horizontal direction is fixed), when the isolation holes 60 are not spaced apart in the horizontal direction (the isolation holes 60 are arranged overlapping or adjacently in the horizontal direction, for example...). Figure 7As shown, in order to cover the entire horizontal range of the second light-concentrating part 12, a larger number of isolation holes 60 (i.e., second reflective surfaces 21) are needed. Furthermore, since the isolation holes 60 are spaced apart in the vertical direction, their arrangement occupies more space in the vertical direction of the main body 13. Therefore, in this embodiment, the spaced-apart isolation holes 60 in the horizontal direction helps to reduce the space occupied by the main body 13 in the vertical direction.

[0063] It should be noted that there may be processing errors during the processing of the isolation hole 60. The isolation hole 60 does not extend strictly parallel to the second direction. In some embodiments, the extension direction of the isolation hole 60 may also have an angle (within 10°) with the second direction, which also falls within the protection scope of this application.

[0064] It is worth mentioning that in some embodiments, the multiple isolation holes 60 can extend in multiple directions to avoid reducing the structural strength of the main body 13 by extending the isolation holes 60 in the same direction. By extending the isolation holes 60 in multiple directions, it is beneficial to improve the strength of the main body 13 and extend its service life.

[0065] In addition, in some embodiments, the isolation hole 60 may also include multiple hole segments, each hole segment being arranged at an angle (each hole segment extending in a different direction), and is not limited thereto.

[0066] like Figure 4-6 The diagram shows some arrangements of the isolation holes 60. The black part in the diagram is a schematic diagram of the isolation junction arrangement, but it is not limited to these.

[0067] In some embodiments, such as Figure 7 As shown, a projection plane λ is set perpendicular to the first direction. The orthographic projections of adjacent isolation holes 60 on the projection plane λ are adjacent to each other, and the isolation holes 60 are spaced apart along the first direction.

[0068] The isolation holes 60 are spaced apart along the first direction, as detailed in the previous embodiment, and will not be repeated here. In this embodiment, there is no gap between adjacent isolation holes 60 in the third direction (the main light-emitting direction of the light guide component 10, the same below). The isolation holes 60 (second reflective surface 21) can cover the light-emitting range of the second light-concentrating part 12 in the third direction, which improves the utilization rate of light and is conducive to improving the brightness of the light.

[0069] In some embodiments, the cross-section of the isolation hole 60 is triangular or fan-shaped.

[0070] For example in Figure 3 In the embodiment shown, the two right-angled sides have regular shapes, which can reduce light occlusion and allow light to enter the light guide channel 30 smoothly. In practical applications, the cross-sectional shape can be selected according to design requirements, processing methods, etc., and is not limited to this.

[0071] In some embodiments, the first reflective surface 131 is provided with a diffusion pattern. This can improve the uniformity of light and the uniformity of illumination.

[0072] On the other hand, this application also relates to a vehicle lamp, including any of the aforementioned light guide components 10.

[0073] The technical solution provided in this application aims to process light emitted from different light sources by setting the first focusing part 11 and the second focusing part 12 respectively, avoiding the same focusing part from corresponding to two different light sources at the same time. It can ensure that each light source is arranged at the focal point of the focusing part, reducing light divergence and improving the lighting effect and light efficiency. Moreover, one focusing part corresponds to one light source, which is conducive to improving heat dissipation efficiency and avoiding mutual thermal influence between different light sources, thus affecting the light efficiency. In addition, the spaced isolation structure 20 provides space for the propagation of light and will not affect the final lighting effect.

Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships. In this application, "at least one" means one or more, and "more than one" means two or more.
