Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and more particularly to an optical component, a vehicle lamp, and a vehicle. Background Technology

[0002] As a low-cost optical form with high frontal uniformity, light guides have been widely used in recent years in various signal light functions, including daytime running lights, front and rear turn signals, front and rear position lights, and brake lights. In practical applications, light guide teeth are added to one side of the light guide, so that light is reflected by the light guide teeth and emitted from the side of the light guide away from the light guide teeth. However, existing circular light guides are limited by manufacturing processes, resulting in a limitation on the light emission width, which cannot meet the needs of applications with larger light emission widths.

[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, and to provide an optical component, a vehicle lamp, and a vehicle.

[0005] According to one aspect of this application, an optical component is provided having a first orientation, the optical component comprising:

[0006] The light guide includes a main body, a first widening portion, and a second widening portion, wherein the first widening portion and the second widening portion are disposed on both sides of the main body in a first direction; a bracket is disposed on the side of the light guide away from the light-emitting surface, and the bracket is used to fix the light guide.

[0007] The main body has light guide teeth spaced apart along the length of the light guide on the surface near the bracket, and the cross-section of the main body is rectangular.

[0008] In one embodiment, the first widening portion has a first surface on the side facing the bracket, and the second widening portion has a second surface on the side facing the bracket; in the first direction, the distance from the first surface to the connection point between the main body and the first widening portion gradually increases along the direction of the bracket toward the light guide, and the distance from the second surface to the connection point between the main body and the second widening portion gradually increases along the direction of the bracket toward the light guide.

[0009] In one embodiment, both the first surface and the second surface are planar.

[0010] In one embodiment, the angle between the first surface and the surface of the main body facing the bracket is α, satisfying: 125°≤α≤135°; and / or, the angle between the second surface and the surface of the main body facing the bracket is β, satisfying: 125°≤β≤135°.

[0011] In one embodiment, α = β = 130°.

[0012] In one embodiment, the size of the main body in the first direction is h mm, satisfying: 5 ≤ h ≤ 15.

[0013] In one embodiment, h = 10.

[0014] In one embodiment, the portion of the bracket facing the light guide is provided with a reflective layer.

[0015] According to another aspect of this application, a vehicle lamp is provided, including any of the optical components described above.

[0016] According to another aspect of this application, a vehicle is provided, including the aforementioned vehicle lights.

[0017] The beneficial effects of this application are: by adjusting the size of the main body in the first direction, the illumination width of the light guide in the first direction can be adjusted; since the cross-section of the main body is rectangular, when adjusting the longitudinal size of the main body to meet the different illumination width requirements, the lateral size of the main body does not need to be adjusted.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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.

[0029] The optical components, headlights, and vehicles described in this application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] In existing technologies, circular light guides are limited by manufacturing processes, resulting in a limitation on the light-emitting width, which cannot meet the requirements for applications with larger light-emitting widths.

[0031] To address the aforementioned technical problems, this application provides an optical component with a first direction. The optical component includes a light guide and a support. The light guide includes a main body, a first widening portion, and a second widening portion, with the first widening portion and the second widening portion disposed on opposite sides of the main body in the first direction. The support is disposed on the side of the light guide away from the light-emitting surface to fix the light guide. The main body has light guide teeth spaced along the length of the light guide on its surface facing the support, and the cross-section of the main body is rectangular.

[0032] By adjusting the dimensions of the main body in the first direction, the illumination width of the light guide in that direction can be adjusted. Since the cross-section of the main body is rectangular, when adjusting the longitudinal dimensions of the main body to meet different illumination width requirements, the lateral dimensions of the main body do not need to be adjusted. This design ensures that the lateral dimensions of the main body (light guide) are relatively small, meaning the light guide does not occupy lateral space, providing ample installation and operation space for the lateral layout of the vehicle lights. This will be explained in detail below.

[0033] See Figure 1-3 In one embodiment, the optical component has a first direction (e.g., Figure 3As shown in the X direction (hereinafter the same), the optical component includes a light guide 10; the light guide 10 includes a main body 11, a first widening part 12 and a second widening part 13, the first widening part 12 and the second widening part 13 are disposed on both sides of the main body 11 in a first direction; the side of the light guide 10 away from the light emitting surface 30 is configured as a bracket 20, the bracket 20 is used to fix the light guide 10; wherein, the surface of the main body 11 facing the bracket 20 is provided with light guide teeth 111 at intervals along the length direction of the light guide 10, and the cross-section of the main body 11 is rectangular.

[0034] For ease of explanation, in the following embodiments, both the horizontal and vertical directions are... Figure 3 Based on perspective.

[0035] By adjusting the dimensions of the main body 11 in the first direction (i.e., the longitudinal dimension), the illumination width of the light guide 10 in the first direction can be adjusted. Since the cross-section of the main body 11 is rectangular, when adjusting the longitudinal dimension of the main body 11 to meet the needs of different illumination widths, the lateral dimension of the main body 11 does not need to be adjusted. This setting ensures that the lateral dimension of the main body 11 (light guide 10) is relatively small, that is, the light guide 10 will not occupy lateral space, and can provide sufficient installation and operation space for the lateral layout of the vehicle headlight. Compared with the cylindrical light guide 10 in the prior art, when it is necessary to adjust the illumination width in the first direction, it is often necessary to increase the diameter of the light guide 10, which not only increases the manufacturing difficulty and production cost, but also increases the lateral dimension of the light guide 10 and occupies lateral space.

[0036] It should be noted that light is coupled into the light guide 10 from the coupling surface (i.e., the light incident surface). After total internal reflection on the light guide tooth 111, the light is deflected and then emitted from the light exit surface 30. When light shines on the first widening portion 12 and the second widening portion 13, total internal reflection can occur, and the light can propagate along the length of the light guide 10 inside the light guide 10, which can effectively increase the length of the light guide 10. In some embodiments, the cross-section of the first widening portion 12 and the second widening portion 13 can be semi-circular, but is not limited to this.

[0037] In some embodiments, the uniformity of light emitted from the light-emitting surface 30 can be controlled by rationally designing the angle, tooth height, tooth spacing, and tooth width of the light guide tooth 111; it should also be noted that the farther the light guide tooth 111 is from the light source, the greater the tooth depth of the light guide tooth 111 (e.g., ...). Figure 2 As shown in the figure, it can ensure the uniformity of brightness of each tooth position along the length of the light guide 10.

[0038] See Figure 3In one embodiment, the first widening portion 12 has a first surface 121 on the side facing the bracket 20, and the second widening portion 13 has a second surface 131 on the side facing the bracket 20. In the first direction, the distance from the first surface 121 to the connection point between the main body portion 11 and the first widening portion 12 gradually increases along the direction of the bracket 20 toward the light guide 10, and the distance from the second surface 131 to the connection point between the main body portion 11 and the second widening portion 13 gradually increases along the direction of the bracket 20 toward the light guide 10.

[0039] In this embodiment, both the first surface 121 and the second surface 131 face to the right (e.g., Figure 3 As shown, the light rays reflected to the first widening section 12 and the second widening section 13 are reflected by the first surface 121 and the second surface 131 and emitted from the light-emitting surface 30. This can effectively increase the longitudinal illumination width of the light guide 10. By setting the first surface 121 and the second surface 131, additional illumination areas are formed on the upper and lower sides of the illumination area formed by the main body 11, which can meet a wider range of longitudinal light emission width. The illumination width can be increased without increasing the longitudinal dimension of the main body 11. Under the same illumination width, the longitudinal dimension of the light guide 10 can be effectively reduced, reducing the production cost and the longitudinal space occupied by the light guide 10. In addition, after the light is reflected by the first surface 121 and the second surface 131, the problem of insufficient longitudinal light emission of the cylindrical light guide 10 in the prior art can be solved, and the illumination effect is improved.

[0040] In some embodiments, the light reflected by the first surface 121 and the second surface 131 can not only increase the illumination width, but also reflect the light to the desired light output direction according to the design of the light guide 10, so as to meet the diverse design requirements of the light guide 10.

[0041] See Figure 3 In one embodiment, both the first surface 121 and the second surface 131 are planar. Compared to curved surfaces, planar surfaces allow for better control of the illumination width of the light guide 10 in the first direction, reducing design complexity. The angle between the first surface 121 and the surface of the main body 11 facing the support 20 is α, satisfying: 125°≤α≤135°, such as 125°, 130°, 135°, etc.; the angle between the second surface 131 and the surface of the main body 11 facing the support 20 is β, satisfying: 125°≤β≤135°, such as 125°, 130°, 135°, etc.

[0042] By setting the angle between the first surface 121 and the second surface 131, the direction of light reflected from the first surface 121 and the second surface 131 can be controlled. The tilt angle of the first surface 121 and the second surface 131 can be adjusted, thereby adjusting the illumination height to meet the needs of different illumination widths. When the value of α is less than 125°, the first surface 121 tends to be horizontal. Figure 3(View angle, the same below) When light cannot be reflected by the first surface 121 to the area above the illumination area formed by the main body 11, the illumination width cannot be increased, and the illumination effect formed by the main body 11 will also be affected. When the value of α is greater than 135°, the first surface 121 is close to a vertical state. The illumination area formed by the light after total internal reflection by the first surface 121 is biased above the illumination area formed by the main body 11. Discontinuity is likely to occur at the junction of the two illumination areas, which is not conducive to the overall illumination effect. In summary, when 125°≤α≤135°, the illumination width can be increased while ensuring the full emission of light from both ends of the longitudinal direction of the light guide 10, resulting in a good illumination effect. The value of β is similar to that of α, and will not be elaborated here.

[0043] It should be noted that in this embodiment, the first surface 121 and the second surface 131 are symmetrically arranged on the upper and lower sides of the main body 11, that is, the values ​​of α and β are equal; in some embodiments, the two can also be unequal values, which can be freely selected according to the illumination width or design requirements, and will not be elaborated here.

[0044] In one embodiment, the main body 11 has a dimension of h mm in the first direction, satisfying: 5 ≤ h ≤ 15, for example 5, 10, 15, etc.

[0045] By varying the value of h, different illumination widths can be adjusted, which is convenient. When the value of h is less than 5, the longitudinal dimension of the main body 11 is small, which is not conducive to the processing of the light guide tooth 111 and increases the processing difficulty. When the value of h is greater than 15, the longitudinal dimension of the main body 11 is large, which affects the strength of the main body 11, and the excessive size is not conducive to the overall design of the vehicle headlight. In summary, when 5≤h≤15, different illumination widths can be adjusted, while also being beneficial to the processing and shaping of the light guide 10 and its service life.

[0046] See Figure 3 and Figure 4 In one embodiment, the portion of the bracket 20 facing the light guide 10 is provided with a reflective layer 21.

[0047] In this embodiment, when adjusting the longitudinal dimension of the main body 11, the transverse dimension of the main body 11 remains unchanged, that is, the light guide 10 is thinner, and the reflective layer 21 on the bracket 20 can be seen through the light guide 10. By setting the color of the reflective layer 21, the reflective layer 21 has a decorative function when the light guide 10 is not lit, which enhances the overall appearance and effectively improves the overall static effect. In addition, in this embodiment, the reflective layer 21 is a high-reflection layer. When the light guide 10 is lit, some light will be reflected by the reflective layer 21 and emitted from the light-emitting surface 30, which enhances the illumination and improves the illumination effect.

[0048] It should be noted that a high-reflectivity layer refers to a coating with high reflectivity, used to enhance the reflective effect of light. High-reflectivity materials can make the light emitted by the light guide 10 brighter and more focused, improving the vehicle's lighting effect and visibility; this configuration can effectively reduce energy loss and make the light more efficient.

[0049] On the other hand, this application also relates to a vehicle lamp, including any of the aforementioned optical components.

[0050] On the other hand, this application also relates to a vehicle including the aforementioned headlights.

[0051] The technical solution provided in this application aims to adjust the illumination width of the light guide 10 in the first direction by adjusting the size of the main body 11 in the first direction. Since the cross-section of the main body 11 is rectangular, when adjusting the longitudinal size of the main body 11 to meet the different illumination width requirements, the lateral size of the main body 11 does not need to be adjusted. This setting can ensure that the lateral size of the main body 11 (light guide 10) is relatively small, that is, the light guide 10 will not occupy the lateral space, and can provide sufficient installation and operation space for the lateral layout of the vehicle lights.
