Description

Technical Field

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

[0002] With the evolving trends in automotive lighting, styling diversity is becoming increasingly important. The application of thick-walled components in automotive lights will become more widespread, and headlights with thick-walled component designs are gradually gaining market share. Previously, automotive headlight designs were relatively simple, and most thick-walled component optical systems could meet viewing angle regulations. However, in recent years, with the diversification of headlight designs and the increasing demands on signal light design, the light-emitting position and the size of the emitting area are subject to various limitations. Therefore, more and more thick-walled component optical systems are failing to adequately meet wide viewing angle regulations. Currently, when a wide viewing angle cannot meet regulations, the only solution is to add patterns to the inside of the lens. However, creating viewing angle patterns on the inside of the lens significantly affects the static appearance and lighting effect of the lamp, reducing its overall quality.

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

[0032] 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.

[0033] 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.

[0034] The light guide component, optical module, and vehicle lamp in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the existing technology, viewing patterns are set on the inside of the lens to meet the viewing regulations. However, the creation of viewing patterns on the inside of the lens greatly affects the static appearance and lighting effect of the luminaire, reducing the quality of the luminaire.

[0036] To address the aforementioned technical problems, this application provides a light guide component. The light guide component has a first light-emitting surface and a first light-incident surface. The first light-emitting surface is configured to receive light incident from the first light-incident surface. The first light-emitting surface is divided into a diffusion region and a reflection region. The diffusion region has a diffusion pattern configured to diffuse light incident on it. The reflection region has a reflection pattern, which has adjacent, angled first reflective surfaces and a light-emitting sub-surface. The first reflective surfaces are configured to totally reflect light incident on them and emit it perpendicular to the light-emitting sub-surface. The normal of the light-emitting sub-surface is angled to the main light-emitting direction of the light guide component. This will be described in detail below.

[0037] See Figure 1 , Figure 3 , Figure 4 and Figure 7 In one embodiment, the light guide component 10 has a first light emitting surface 11 and a first light incident surface 12. The first light emitting surface 11 is configured to receive light incident from the first light incident surface 12. The first light emitting surface 11 is divided into a diffusion area and a reflection area. The diffusion area is provided with a diffusion pattern 111, which is configured to diffuse the light incident on the diffusion pattern 111. The reflection area is provided with a reflection pattern 112, which has a first reflective surface 1121 and a light emitting sub-surface 1122 that are adjacent to each other and set at an angle. The first reflective surface 1121 is configured to totally reflect the light incident on the first reflective surface 1121 and emit it perpendicular to the light emitting sub-surface 1122. The normal of the light emitting sub-surface 1122 is set at an angle to the main light emitting direction of the light guide component 10.

[0038] The light incident on the diffusion area is distributed and diffused by the diffusion pattern 111, effectively improving the uniformity of light output of the light guide component 10. At the same time, the light incident on the reflection area is totally reflected by the first reflection surface 1121 and then emitted perpendicularly to the photoelectric surface 1122. This ensures that all the light reflected by the first reflection surface 1121 is emitted from the photoelectric surface 1122 to the corresponding area, effectively reducing light loss and ensuring that the illumination of the corresponding area meets the design requirements. When the light reflected from the first reflection surface 1121 is not perpendicular to the photoelectric surface 1122, some of the light will be refracted when passing through the photoelectric surface 1122, so that not all the light emitted from the photoelectric surface 1122 reaches the corresponding area, and the illumination of the corresponding area does not meet the design requirements.

[0039] It should be noted that the corresponding area is the area where the light from the light guide component 10 ultimately needs to be illuminated or irradiated during actual use; in this embodiment, the diffusion pattern 111 can be a fisheye pattern (a curved surface protruding towards the light-emitting side of the light guide component 10, such as...). Figure 4 As shown in the figure, in some embodiments there may be other forms of configuration. The specific structure of the light guide component 10 and the required static appearance are taken into account. As long as the light can be evenly diffused to the corresponding area to meet the needs of use, it is not limited to this.

[0040] Additionally, the normal of the photon-emitting surface 1122 (such as...) Figure 3 (as shown in the Y direction) and the main light output direction of the light guide component 10 (as shown in the Y direction) Figure 3 The light emitted from the light-emitting surface 1122 is angled to the main light-emitting direction of the light guide component 10, as shown in the X direction. The light reflected by the reflective pattern 112 is distributed to a wide viewing angle area, which meets the regulatory requirements.

[0041] In some embodiments, light is refracted to meet regulatory requirements by adding a patch-like viewing pattern to the outer lens. However, creating a viewing pattern on the inner side of the lens 60 greatly affects the static appearance and lighting effect of the luminaire, reducing the quality of the luminaire. In this embodiment, by setting a reflective pattern 112 on the first light-emitting surface 11, the viewing regulation requirements are met while the luminaire has a good static appearance, thus improving the quality of the luminaire.

[0042] See Figure 4 In one embodiment, the connection between the first reflecting surface 1121 and the photon emitting surface 1122 is provided with a rounded corner 1123, and the radius of the rounded corner 1123 is R mm, which satisfies: 0.05 ≤ R ≤ 0.15, such as 0.05, 0.10, 0.15, etc.

[0043] When there is no rounded corner 1123 between the first reflective surface 1121 and the photoemitting surface 1122, the connection between the two is easily damaged by external collisions, which will affect the integrity of the first reflective surface 1121 and the photoemitting surface 1122, and thus affect the reflection effect of light. In addition, without the rounded corner 1123, the connection between the two is too sharp and can easily scratch the operator during the assembly process. Therefore, the rounded corner 1123 ensures the reflection effect of the reflective pattern 112 on light.

[0044] When the value of R is less than 0.05, the value of R is too small. Although the smaller the value of R, the larger the effective area (area acting on the light) of the first reflecting surface 1121 and the photon emitting surface 1122, the smaller the value of R will increase the processing difficulty and processing cost. When the value of R is greater than 0.15, the value of R is too large, and the effective area of ​​the first reflecting surface 1121 and the photon emitting surface 1122 becomes smaller, which is not conducive to the reflection of light. Because more light will hit the rounded corner 1123 and cannot be totally reflected, the light cannot be distributed to the corresponding area, which cannot meet the design requirements of the light guide component 10. However, the larger the value of R, the lower the processing difficulty and the lower the processing cost.

[0045] Therefore, when 0.05≤R≤0.15, it can ensure both reasonable processing difficulty and processing cost, and also ensure that the first reflecting surface 1121 and the photon emitting surface 1122 have reasonable effective areas.

[0046] In some embodiments, when the overall size of the light guide component 10 is large, the size of the reflective pattern 112 will also increase accordingly. When R takes a large value, the effect on the effective area of ​​the first reflective surface 1121 and the light-emitting surface 1122 is small. In this case, the value of R can be greater than 0.15, taking into account factors such as the actual size of the product and usage requirements.

[0047] See Figure 3 and Figure 5 In one embodiment, the first light-emitting surface 11 and the first light-incident surface 12 are disposed opposite to each other; the first light-incident surface 12 is provided with a first planar pattern 121, the first planar pattern 121 includes a plurality of arrays of first sub-planes 1211, the first sub-planes 1211 being configured to be substantially perpendicular to the incident light.

[0048] The first sub-plane 1211 is configured perpendicular to the incident light, ensuring that the incident light does not deflect after passing through the first sub-plane 1211. This avoids refraction and diffusion of the incident light when passing through the first sub-plane 1211, making the light entering the light guide component 10 more concentrated. Most of the light can directly hit the first light emitting surface 11 opposite to the first light incident surface 12, effectively improving the light intensity. At the same time, patterns are provided on both opposite sides of the light guide component 10 (the first light emitting surface 11 has a diffusion pattern 111 and a reflection pattern 112, and the first light incident surface 12 has a first planar pattern 121), preventing other internal components of the lamp, such as the printed circuit board 30, from being visible through the light guide component 10 when the lamp is static, thus giving the lamp a good appearance when viewed statically.

[0049] It should be noted that the array can be an arc array or a straight array, and the design is based on the specific shape of the first light-incident surface 12. By setting multiple first sub-planes 1211 in the array, it can be ensured that the light rays incident at each position are perpendicular to the corresponding first sub-plane 1211.

[0050] In addition, due to the dimensional deviations in the parts, the first sub-plane 1211 is basically perpendicular to the incident light, that is, the incident light and the first sub-plane 1211 are not necessarily absolutely perpendicular, and there may be a certain deviation.

[0051] See Figure 8 In one embodiment, the reflective area is disposed at the edge of the first light-emitting surface 11.

[0052] In this embodiment, the reflective area (i.e., reflective pattern 112) is located at the edge of the first light-emitting surface 11. The reflective area will not affect the overall lighting effect of the first light-emitting surface 11. When the reflective area is located in the middle part of the first light-emitting surface 11, some light in the middle area will deviate from the main light-emitting direction of the light guide component 10 under the action of the reflective pattern 112 (see the aforementioned embodiment for details), making the light in this part darker, which is not conducive to the overall lighting effect of the light guide component 10.

[0053] The above-mentioned defects will not exist when the reflective area is set at the edge of the first light-emitting surface 11, and the luminaire has a good static appearance when the reflective area is set at the edge.

[0054] See Figure 2 , Figure 3 , Figure 5 as well as Figure 6 On the other hand, this application also relates to an optical module, including any of the aforementioned light guide components 10; the optical module further includes a light processing component 20, which is disposed on the light-incident side of the light guide component 10, and the light guide component 10 is configured to receive light emitted from the light processing component 20; the light processing component 20 has a second light-emitting surface 21, a second light-incident surface 22 and a second reflective surface 23, and the second reflective surface 23 is configured to adjust the light incident from the second light-incident surface 22 into parallel light rays 24 and direct them toward the second light-emitting surface 21; the second light-emitting surface 21 is provided with a second planar pattern 211, the second planar pattern 211 including a plurality of arrays of second sub-planes 2111, the second sub-planes 2111 being substantially perpendicular to the parallel light rays 24.

[0055] The second sub-plane 2111 is configured to be perpendicular to the parallel light ray 24, which ensures that the parallel light ray 24 does not deflect after passing through the second sub-plane 2111. This avoids the parallel light ray 24 from being refracted and diffused when passing through the second sub-plane 2111, making the light incident on the light guide component 10 more concentrated. Most of the light can be directly incident on the first light incident surface 12, effectively improving the intensity of the light.

[0056] It should be noted that the array can be an arc array or a straight array, and the design should be based on the specific shape of the second light-emitting surface 21. By setting multiple second sub-planes 2111 in the array, it can be ensured that the parallel light rays 24 incident at each position are perpendicular to the corresponding second sub-plane 2111.

[0057] In addition, due to the dimensional deviations in the parts, the second sub-plane 2111 is basically perpendicular to the parallel ray 24. That is, the parallel ray 24 and the second sub-plane 2111 are not necessarily absolutely perpendicular, and there may be a certain deviation.

[0058] In some embodiments, the first light-incident surface 12 is provided with a first planar pattern 121, as detailed in the foregoing embodiments, and will not be repeated here; the combination of the first planar pattern 121 and the second planar pattern 211 can ensure the intensity of the light emitted from the first light-emitting surface 11 and improve the overall lighting effect.

[0059] See Figure 2 , Figure 4 and Figure 8 In one embodiment, the optical module further includes a printed circuit board 30 and a light-emitting unit 31. The light-emitting unit 31 is disposed on the portion of the printed circuit board 30 opposite to the second light-incident surface 22. With a reference plane perpendicular to the main light-emitting direction of the light guide component 10 as the projection plane, the orthographic projection of the second light-emitting surface 21 and the printed circuit board 30 on the reference plane is located within the orthographic projection of the first light-incident surface 12 on the reference plane.

[0060] In this embodiment, the area of ​​the first light-incident surface 12 is relatively large, capable of covering the second light-exiting surface 21 and the second printed circuit board 30 (e.g., Figure 8 As shown), when the lamp is static, the internal components (printed circuit board 30) can be avoided, giving the lamp a good static appearance. In addition, the large area of ​​the first light-incident surface 12 can fully receive the light emitted from the second light-emitting surface 21, effectively increasing the intensity of the light emitted from the first light-emitting surface 11 and improving the lighting effect of the lamp.

[0061] It should be noted that the reference plane is as follows: Figure 3 The midplane λ is shown.

[0062] See Figure 1 , Figure 2 and Figure 6In one embodiment, the printed circuit board 30 is positioned on the light processing component 20 by a positioning structure 40, which includes a positioning hole 41 and four positioning posts 42. The positioning hole 41 is disposed on the printed circuit board 30, and the positioning posts 42 are disposed on the light processing component 20. Each positioning post 42 includes a first post segment 421 and a second post segment 422 connected together. The cross-sectional area of ​​the first post segment 421 is larger than the cross-sectional area of ​​the second post segment 422, so as to form a limiting surface 423 at the connection between the first post segment 421 and the second post segment 422. The second post segment 422 is inserted into the positioning hole 41 to limit the relative position of the printed circuit board 30 and the light processing component 20 in the radial direction of the second post segment 422. The printed circuit board 30 is configured to be pressed against the limiting surface 423.

[0063] The printed circuit board 30, through the positioning structure 40, can limit the relative position between the printed circuit board 30 and the light processing component 20, ensuring that the light emitted by the light-emitting unit 31 enters the light processing component 20 stably and reliably. The structure is simple, and the position of the printed positioning plate in the radial direction of the second column segment 422 can be limited simply by inserting the second column segment 422 into the positioning hole 41. At the same time, the printed circuit board 30 is pressed onto the limiting surface 423, which limits the relative position between the printed circuit board 30 and the light processing component 20 in the axial direction of the second column segment 422.

[0064] In this embodiment, the distance between the printed circuit board 30 and the light processing component 20 can be controlled by setting the distance between the limiting surface 423 and the light processing component 20, thereby controlling the distance between the light-emitting unit 31 and the second light-incident surface 22. The distance can be set according to factors such as the power and light-emitting range of the light-emitting unit 31.

[0065] In this embodiment, the second column segment 422 can be a hot riveting column to press the printed circuit board 30 onto the limiting surface 423; in some embodiments, it can also be fixed by screws or other means, and is not limited to this.

[0066] In one embodiment, the second incident surface 22 is a curved surface composed of multiple interconnected cylindrical segments to diffuse the light incident on the second incident surface 22. This structure is simple, effectively diffuses the light, and significantly improves the overall illumination range.

[0067] See Figure 1 , Figure 2 , Figure 7 and Figure 8In one embodiment, the optical module further includes a decorative ring 50; the light guide component 10 includes a first sub-part 13 and a second sub-part 14, the cross-sectional area of ​​the first sub-part 13 is smaller than the cross-sectional area of ​​the second sub-part 14, so as to form a mounting surface 15 at the connection between the first sub-part 13 and the second sub-part 14, a first light emitting surface 11 is disposed on the side of the first sub-part 13 away from the second sub-part 14, and a first light entering surface 12 is disposed on the side of the second sub-part 14 away from the first sub-part 13; the decorative ring 50 is sleeved on the first sub-part 13 and attached to the mounting surface 15.

[0068] In this embodiment, the decorative ring 50 is made of black light-shielding material, and the edge of the decorative ring 50 extends beyond the first light-incident surface 12. The decorative ring 50 serves a decorative purpose, giving the lamp a good static appearance. At the same time, the decorative ring 50 can also shield light, preventing light leakage when the lamp is lit, thus improving the lighting effect of the lamp.

[0069] It should be noted that the decorative ring 50 and the light guide component 10 can be processed by two-color injection molding, or they can be fastened together by screws, hot riveting, etc., and are not limited to these methods.

[0070] On the other hand, this application also relates to a vehicle light, including any of the aforementioned optical modules.

[0071] In this embodiment, the headlight is the right rear signal light (the side of the vehicle closest to the passenger side). When the light guide component 10... Figure 8 When used at the angle shown, the light is distributed to the right by the reflective pattern 112, which widens the viewing angle and meets regulatory requirements.

[0072] The technical solution provided in this application aims to distribute and diffuse the light incident on the diffusion pattern 111 (diffusion area) by setting the diffusion pattern 111, effectively improving the overall uniformity of light output of the light guide component 10. At the same time, the light incident on the reflection area is totally reflected by the first reflection surface 1121 and then emitted perpendicularly to the light-emitting sub-surface 1122, which can ensure that all the light reflected by the first reflection surface 1121 is emitted from the light-emitting sub-surface 1122 to the corresponding area, effectively reducing the loss of light caused by the refraction lamp and ensuring that the illumination of the corresponding area meets the design requirements. The normal of the light-emitting sub-surface 1122 is set at an angle to the main light output direction of the light guide component 10, so that the light reflected by the reflection pattern 112 is distributed to a wide viewing angle area, which meets the regulatory requirements.
