Description
Technical Field
[0001] This application relates to the field of vehicle signal light technology, and in particular to a signal light module and vehicle light. Background Technology
[0002] With the rapid development of intelligent vehicle technology, the demand for diversified and dynamic headlight lighting effects is increasing. Enriching the lighting effects of headlights can enhance the vehicle's premium feel and overall experience, and adapt to complex scenarios.
[0003] Vehicle signal lights are primarily used to convey vehicle status, operational intentions, or warning information, ensuring driving safety and traffic order. Currently, signal lights can only achieve a single illumination effect. This static design can only meet basic signal transmission needs and does not conform to the development trend of diversified and dynamic lighting effects. Summary of the Invention
[0004] This application provides a signal light module and vehicle light, aiming to improve the problem of the single light output effect of signal lights.
[0005] The specific technical solution is as follows: In a first aspect, this application provides a traffic light module, comprising: a light source; a first lens disposed on the light-emitting side of the light source; a second lens disposed on the side of the first lens opposite to the light source; the second lens comprising a plurality of optical interface pairs, each optical interface pair comprising a first surface and a second surface disposed opposite to each other, the second lens being rotatable about a first direction as an axis, such that different optical interface pairs are located in the light path emitted by the first lens, the first direction being perpendicular to the light-emitting direction of the light source; wherein, at least some of the optical interface pairs have different optical structures on their first surfaces, and / or, at least some of the optical interface pairs have different optical structures on their second surfaces, so that the traffic light module forms different light emission effects.
[0006] The signal light module of this embodiment includes a rotatable second lens with multiple optical interface pairs. When the second lens rotates, each optical interface pair can be positioned on the outgoing light path of the first lens. Furthermore, at least some optical interface pairs have differences in the optical structure of their first and / or second surfaces. This effectively makes each optical interface pair an independent light effect template. Through differences in surface structure and the rotation of the second lens, different optical interface pairs can switch to the outgoing light path of the first lens, resulting in different light emission effects from the signal light module. Firstly, a standard optical interface pair can be set on the second lens. When this standard optical interface pair is on the outgoing light path of the first lens, the signal light module can exhibit a standard signal light optical effect. Then, the surfaces of the other optical interface pairs are designed individually. Therefore, the signal light module of this embodiment can also possess various other light emission effects beyond the standard signal light effect, expanding the signal light module from basic driving applications to more complex scenarios. This improves the diversity of light emission effects and the flexibility of the signal light module, thereby enhancing the vehicle's premium feel and user experience.
[0007] In some embodiments, the first surface of each optical interface pair is the light-incident surface, and the second surface is the light-exit surface.
[0008] This configuration offers two advantages. First, it reduces the number of optical interface switching operations, thereby improving the convenience, stability, and reliability of rotation control. Second, this embodiment is suitable for vehicle models with fewer requirements for various optical effects, and it also helps reduce the design complexity of the second lens, further lowering costs.
[0009] In some embodiments, when the first surface is located between the second surface and the first lens, the first surface is the light-incident surface and the second surface is the light-exit surface; when the second surface is located between the first surface and the first lens, the first surface is the light-exit surface and the second surface is the light-incident surface.
[0010] This configuration allows each optical interface pair to achieve two optical effects. When the required number of optical effects is the same, the number of optical interface pairs required in this embodiment is only half that of the previous embodiments. This reduces the volume and size of the second lens. For example, when two light output effects are required, the second lens in the previous embodiment needs to be a cube, while the second lens in this embodiment can have a flat structure and does not need to be a cube. This facilitates the miniaturization and compactness of the traffic light module, improving installation convenience. Secondly, each optical interface pair can achieve two optical effects, further enhancing the diversity and flexibility of the light output effects and covering more application scenarios. Furthermore, it also offers advantages such as low cost, simple structure, and high scalability.
[0011] In some embodiments, the second lens includes a lens body and a rotating shaft connected to the lens body. The signal light module further includes a driving member, the output end of which is connected to the rotating shaft to drive the lens body to rotate. The driving member is provided with a Hall sensor, and / or the rotating shaft is provided with an angle sensor.
[0012] This configuration allows for the detection of the rotation angle at the output end of the drive component, thereby obtaining the rotation position of the second lens in real time. This enables precise control of the second lens's rotation as needed, thus improving the accuracy and precision of light effect switching.
[0013] In some embodiments, the lens body has the plurality of optical interface pairs; The lens body further includes a third surface and a fourth surface disposed opposite to each other along the first direction, wherein the third surface is connected to the fourth surface through the plurality of optical interfaces; The orthographic projections of the third and fourth surfaces onto the first direction are regular polygons, and the regular polygons have an even number of sides.
[0014] This configuration offers several advantages. First, the geometric center of the even-sided regular polygon can perfectly coincide with the rotation axis, minimizing the eccentricity during lens rotation and thus reducing frictional losses between the rotation axis and bearings, thereby extending rotational life. Second, each optical interface pair of the even-sided regular polygon corresponds to a fixed central angle, allowing driving components such as servo motors to achieve precise switching with a fixed number of steps, improving the accuracy of light output effect switching and reducing errors. Third, multiple optical interface pairs correspond precisely to each pair of sides of the regular polygon, enhancing the ease of processing and manufacturing, reducing costs, and increasing yield. Furthermore, in this embodiment, only the orthographic projections of the third and fourth surfaces in the first direction X are defined as regular polygons, constraining only the radial contours of the end faces, without constraining the specific shape of the side surfaces (multiple optical interface pairs) connecting the two end faces. Therefore, the first and second surfaces of multiple optical interface pairs can be planar or curved, further improving the ease of achieving different light output effects.
[0015] In some embodiments, the plurality of optical interface pairs include a first optical interface pair and a second optical interface pair; the first surface of the first optical interface pair is a smooth plane, and the second surface of the first optical interface pair is formed by splicing together a plurality of sub-planes, wherein any two adjacent sub-planes are not coplanar; the first surface of the second optical interface pair is a smooth plane, and the second surface of the second optical interface pair is provided with optical patterns.
[0016] Multiple optical interface pairs include a first optical interface pair and a second optical interface pair. The first surface of the first optical interface pair and the first surface of the second optical interface pair have the same optical structure, but the optical structures of their second surfaces are different. Thus, up to four light emission effects can be formed.
[0017] In some embodiments, the first surface of the first optical interface pair is a smooth plane, the second surface of the first optical interface pair is composed of a plurality of sub-planes spliced together, and any two adjacent sub-planes are not coplanar; the first surface of the second optical interface pair is provided with optical patterns, and the second surface of the second optical interface pair is the same as the second surface of the first optical interface pair.
[0018] The first surface of the first optical interface pair and the first surface of the second optical interface pair have different optical structures, but the optical structures of their second surfaces are the same. Therefore, a maximum of four light emission effects can be formed.
[0019] In some embodiments, the first surface of the first optical interface pair is formed by splicing together a plurality of sub-planes, and any two adjacent sub-planes are not coplanar. The second surface of the first optical interface pair is the same as the first surface of the first optical interface pair. The first surface of the second optical interface pair is provided with a first optical pattern, and the second surface of the second optical interface pair is provided with a second optical pattern.
[0020] The first surface of the first optical interface pair and the first surface of the second optical interface pair have different optical structures, and their second surfaces also have different optical structures. However, the first surface and the second surface of the first optical interface pair have the same optical structure. Therefore, even when the structures of the first optical pattern and the second optical pattern are different, a maximum of three light emission effects can be formed.
[0021] In some embodiments, the plurality of optical interface pairs include a first optical interface pair and a second optical interface pair, wherein the first surface of the first optical interface pair is a light-incident surface, the second surface of the first optical interface pair is a light-outceasing surface, and the second surface of the first optical interface pair is provided with a first filter film. The first surface of the second optical interface pair is the light-incident surface, the second surface of the second optical interface pair is the light-outceasing surface, and the second surface of the second optical interface pair is provided with a second filter film.
[0022] In this design, the first optical interface pair can generate light of a first specific color, and the second optical interface pair can generate light of a second specific color. Therefore, two core color light outputs can be achieved without changing the light source, allowing the signal light module to be adapted to at least two different functions. For example, when outputting red light, the signal light module functions as a brake light; when outputting amber light, the signal light module functions as a turn signal. This configuration, while achieving multi-functionality and multiple light output effects for the signal light module, also helps to reduce cost and size, and simplifies the structure.
[0023] In some embodiments, the plurality of optical interface pairs include a first optical interface pair and a second optical interface pair; the first surface and the second surface of the first optical interface pair are configured as a converging lens group; the first surface and the second surface of the second optical interface pair are configured as a diverging lens group.
[0024] In this way, the first optical interface pair can achieve a long-distance, directional, and concentrated light emission effect with high brightness and good penetration; while the second optical interface pair can achieve a short-distance, wide-angle, and diffused light emission effect with a large light coverage area and soft light. This configuration, while achieving multi-functionality and multi-emission effects for the traffic light module, helps to reduce cost and size and simplify the structure.
[0025] In some embodiments, there are multiple light sources arranged at intervals along the first direction; each light source is provided with a first lens and a second lens.
[0026] This configuration allows for several advantages. First, different signal light units can emit different lighting effects, enhancing the diversity and dynamism of the signal light module's output. The lighting effects of different units can complement each other, resulting in superior and more varied combined lighting effects. Second, different signal light units can also emit the same lighting effect, increasing the final light intensity and coverage area, further improving visibility and overall lighting performance. Third, each signal light unit can independently control the on / off state of its light source and the switching of the second lens's light output effect. This allows for the creation of dynamic lighting effects, such as flowing water effects, further enhancing the dynamism of the lighting effect, supporting complex dynamic scenes, and improving the vehicle's premium feel.
[0027] In some embodiments, the surface of the first lens near the light source is a total reflection surface and is provided with a receiving groove, the light source is opposite to the opening of the receiving groove, and the bottom wall of the receiving groove is provided with a third optical pattern.
[0028] The receiving groove can accurately collect the diffused light from the light source and adapt to the light emission pattern of the light source, thereby improving the light input efficiency and reducing light loss. By setting a third optical pattern on the bottom wall of the receiving groove, it can play a preliminary role in homogenizing the light and improving the uniformity of the incident light.
[0029] In some embodiments, the total reflection surface is provided with a fourth optical pattern, and the surface of the first lens near the second lens is provided with a fifth optical pattern, the fifth optical pattern being configured to provide uniform light.
[0030] By setting a fourth optical pattern on the total internal reflection surface, the light incident efficiency can be further improved and light loss reduced. By setting a fifth optical pattern on the light exiting surface of the first lens, secondary light homogenization can be achieved, which can increase the amount of light entering the second lens and further reduce light loss.
[0031] Secondly, embodiments of this application provide a vehicle light, including the signal light module described in the first aspect. Attached Figure Description

[0038] Vehicle signal lights are primarily used to convey vehicle status, operational intentions, or warning information, ensuring driving safety and traffic order. Currently, signal lights can only achieve a single illumination effect. This static design can only meet basic signal transmission needs and does not conform to the development trend of diversified and dynamic lighting effects.
[0039] Based on the above problems, this application proposes a signal light module and vehicle light to improve the problem of the single light output effect of signal lights.
[0040] like Figure 1 and Figure 2 As shown, in a first aspect, this application provides a traffic light module 10. The traffic light module 10 includes a light source 100, a first lens 200, and a second lens 300. The first lens 200 is disposed on the light-emitting side of the light source 100, and the second lens 300 is disposed on the side of the first lens 200 away from the light source 100. The second lens 300 includes a plurality of optical interface pairs 310, each optical interface pair 310 including a first surface 311 and a second surface 312 disposed opposite to each other. The second lens 300 is rotatable about a first direction X as an axis, so that different optical interface pairs 310 are located in the light path emitted by the first lens 200. The first direction X is perpendicular to the light-emitting direction of the light source 10. At least some of the optical interface pairs 310 have different optical structures for their first surface 311, and / or at least some of the optical interface pairs 310 have different optical structures for their second surface 312, so that the traffic light module 10 forms different light emission effects.
[0041] The signal light module 10 of this application embodiment includes a light source 100, a first lens 200, and a second lens 300. The light source 100 is used to emit light, and it can be an LED (Light Emitting Diode) chip. The light emitted from the light source 100 enters the first lens 200.
[0042] The first lens 200 can perform initial adjustment of the emitted light from the light source 100, optimizing the original emitted light characteristics of the light source and providing a basis for the light effect control of the second lens 300. For example, the first lens 200 can convert the divergent light of the light source 100 (such as a Lambertian light source) into a beam with a slightly smaller divergence angle, ensuring that the energy distribution of the light incident on the second lens 300 is uniform.
[0043] The second lens 300 is disposed on the light-emitting side of the first lens 200. The second lens 300 has multiple optical interface pairs 310. Each optical interface pair 310 refers to a set of two opposing optical functional surfaces on the second lens 300, namely the first surface 311 and the second surface 312. The first surface 311 and the second surface 312 correspond to each other in space, together forming an independent light control channel. For example, please refer to... Figure 1 and Figure 2 The second lens 300 can be designed as a cube, with two sets of optical interface pairs 310 evenly distributed along the circumferential direction of the cube. The first face 311 and the second face 312 of each set are arranged opposite to each other and are parallel to each other.
[0044] Furthermore, the second lens 300 can also rotate about the first direction X as an axis, thereby placing different optical interface pairs 310 in the output light path of the first lens 200. For example, in the initial position, the first group of optical interface pairs 310 is in the output light path of the first lens 200. When the second lens 300 rotates by a preset angle, the first group of optical interface pairs 310 rotates to other positions, and the second group of optical interface pairs 310 rotates into the output light path of the first lens 200. Under this design, the first lens 200 can cooperate with each group of optical interface pairs 310 of the second lens 300 respectively, thereby forming multiple output light paths.
[0045] Furthermore, at least some of the optical interfaces 310 have different optical structures on the first surface 311, and / or at least some of the optical interfaces 310 have different optical structures on the second surface 312. That is, among the multiple sets of optical interfaces 310, at least some optical interfaces have different optical structures on the first surface 311; or, at least some optical interfaces have different optical structures on the second surface 312; or, at least some optical interfaces have different optical structures on both the first surface 311 and the second surface 312. Specifically, the difference in optical structure manifests in at least one of the following: surface curvature (convex, concave, etc.), surface texture (microprism, frosted, optical pattern, irregular surface, etc.), and surface structure (optical film coating, etc.) of the first surface 311 and the second surface 312. For example, the surface curvature and surface texture of the first surface 311 or the second surface 312 of the two optical interfaces 310 are both different.
[0046] The traffic light module 10 of this embodiment includes a rotatable second lens 300, which has multiple optical interface pairs 310. When the second lens 300 rotates, each optical interface pair 310 can be positioned on the outgoing light path of the first lens 200. Furthermore, at least some optical interface pairs 310 have differences in the optical structure of their first surface 311 and / or their second surface 312. This effectively makes each optical interface pair 310 an independent light-emitting template. Through the differences in surface structure and the rotation of the second lens 300, different optical interface pairs 310 switch to the outgoing light path of the first lens 200, thus allowing the traffic light module 10 to exhibit different light emission effects.
[0047] Thus, firstly, a standard optical interface pair 310 can be set on the second lens 300. When this standard optical interface pair 310 is in the output light path of the first lens 200, the signal light module 10 can present a standard signal light optical effect. Then, the surfaces of the other optical interface pairs 310 are designed individually. Therefore, the signal light module 10 of this embodiment can also have various other light output effects besides the standard signal light effect, enabling the signal light module 10 to expand from basic driving to more complex application scenarios. This is beneficial to improving the diversity of light output effects and the flexibility of the signal light module 10, thereby enhancing the premium feel of the vehicle and the user experience.
[0048] Furthermore, the signal light module 10 of this application embodiment can achieve a variety of light output effects simply by using the rotatable second lens 300. Compared with the method of equipping multiple independent light sources or complex light control structures, it is also beneficial to reduce costs and improve the reliability and stability of switching.
[0049] Furthermore, since the number of optical interface pairs 310 of the second lens 300 can be two or more, the optical structure of the first surface 311 and the second surface 312 can be flexibly changed according to the actual situation without changing the overall shape of the second lens 300, which also helps to improve the adaptability and versatility of the signal light module 10.
[0050] Optionally, when each optical interface pair 310 is located on the propagation optical path, the orthographic projection of the first surface 311 and the second surface 312 on the light-emitting surface of the first lens 200 coincides with the light-emitting surface of the first lens 200. Thus, while reducing the volume and size of the second lens 300, light waste can be minimized.
[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the first surface 311 of each optical interface 310 is the light-incident surface, and the second surface 312 is the light-exit surface.
[0052] In this embodiment, the first surface 311 of each optical interface pair 310 is defined as the light-incident surface, and the second surface 312 as the light-exit surface. This configuration means that during rotation, the second lens 300 will only bring the first surface 311 of each optical interface pair 310 closer to the first lens 200. The first lens 200, in conjunction with one optical interface pair 310, produces one optical effect; the number of optical interface pairs 310 determines the number of optical effects. For example, in… Figure 1 In this case, if the second lens 300 rotates only the first surface 311 of the two optical interfaces 310 to face the light-emitting surface of the first lens 200, two optical effects can be produced.
[0053] This configuration offers two advantages. First, it reduces the number of times the optical interface switches to 310, thereby improving the convenience, stability, and reliability of rotation control. Second, this embodiment is suitable for vehicle models with fewer requirements for various optical effects, and it also helps reduce the design complexity of the second lens 300, further lowering costs.
[0054] like Figure 1 and Figure 2 As shown, in some embodiments, when the first surface 311 is located between the second surface 312 and the first lens 200, the first surface 311 is the light-incident surface and the second surface 312 is the light-exit surface; when the second surface 312 is located between the first surface 311 and the first lens 200, the first surface 311 is the light-exit surface and the second surface 312 is the light-incident surface.
[0055] In this embodiment, during the rotation of the second lens 300, if the first surface 311 of each optical interface pair 310 rotates to be opposite to the light-emitting surface of the first lens 200, then the first surface 311 becomes the light-incident surface, and the second surface 312 becomes the light-emitting surface; then, if the second surface 312 of the optical interface pair 310 rotates to be opposite to the light-emitting surface of the first lens 200, then the second surface 312 becomes the light-incident surface, and the first surface 311 becomes the light-emitting surface.
[0056] In other words, when there is a difference in the optical structure between the first surface 311 and the second surface 320 of the optical interface pair 310, each optical interface pair 310 can produce two light emission effects, for example, in Figure 1 and Figure 2 There are two optical interface pairs 310, and the first surface 311 and the second surface 320 of each optical interface pair 310 are different, which can produce a total of four optical effects.
[0057] With this configuration, firstly, each optical interface pair 310 can achieve two optical effects. When the number of optical effects required is the same, the number of optical interface pairs 310 required in this embodiment is only half that in the previous embodiment. This reduces the volume and size of the second lens 300. For example, when two light output effects are required, the second lens 300 in the previous embodiment needs to be a cube, while the second lens 300 in this embodiment can have a flat structure and does not need to be a cube. This is beneficial for improving the miniaturization and structural compactness of the signal light module 10, and improving installation convenience. Secondly, each optical interface pair 310 can achieve two optical effects, which can further improve the diversity and flexibility of light output effects and cover more application scenarios. Furthermore, it also has the advantages of low cost, simple structure, and high scalability.
[0058] like Figures 1 to 3 As shown, in some embodiments, the second lens 300 includes a lens body 301 and a rotating shaft 302 connected to the lens body 301. The signal light module 10 also includes a driver (not shown in the figure), the output end of which is connected to the rotating shaft 302 to drive the lens body 301 to rotate. The driver is provided with a Hall sensor, and / or the rotating shaft 302 is provided with an angle sensor (not shown in the figure).
[0059] This embodiment presents a specific structure for the second lens 300, which includes a lens body 301 and a rotating shaft 302. The lens body 301 and the rotating shaft 302 can be manufactured using an integral molding process. In this way, the driving component drives the lens body 301 to rotate via the rotating shaft 302, so that different optical interface pairs 310 are located on the outgoing light path of the first lens 200.
[0060] Furthermore, a Hall sensor is installed on the drive component. As a rotational positioning feedback device, the Hall sensor can detect the rotation angle of the output end of the drive component, thereby obtaining the rotational position of the second lens 300 in real time. This allows for precise control of the rotation of the second lens 300 as needed, thus improving the accuracy and precision of light effect switching.
[0061] Furthermore, an angle sensor is provided on the rotating shaft 302, which can directly measure the rotation angle of the rotating shaft 302, thereby improving the precision and accuracy of light effect switching.
[0062] By simultaneously equipping the drive unit with a Hall sensor and setting an angle sensor on the rotating shaft 302, the precision and accuracy of light effect switching can be further improved, while also improving the response speed during switching.
[0063] like Figures 3 to 6 As shown, in some embodiments, the lens body 301 forms a plurality of optical interface pairs 310. The lens body 301 also includes a third surface 3011 and a fourth surface 3012 disposed opposite to each other along the first direction X. The third surface 3011 is connected to the fourth surface 3012 through the plurality of optical interface pairs 310. The orthographic projection of the third surface 3011 and the fourth surface 3012 on the first direction X is a regular polygon, and the regular polygon has an even number of sides.
[0064] This embodiment presents a specific structure for the lens body 301. The third surface 3011 and the fourth surface 3012 are the two end faces of the lens body 301, and the rotating shaft 302 can be disposed on the third surface 3011 and / or the fourth surface 3012. Further, the orthographic projections of the third surface 3011 and the fourth surface 3012 in the first direction X are regular polygons. Please refer to... Figures 4 to 6 The orthographic projection can be, for example, a square, a regular hexagon, or a regular octagon. Specifically, a square has two opposite sides forming the first face 311 and the second face 312 of an optical interface pair 310, providing two optical interface pairs 310. Rotating 90° allows switching to another optical interface pair 310. A regular hexagon has three opposite sides forming the first face 311 and the second face 312 of an optical interface pair 310, providing three optical interface pairs 310. Rotating 60° allows switching to another optical interface pair 310. A regular octagon has four opposite sides forming the first face 311 and the second face 312 of an optical interface pair 310, providing four optical interface pairs 310. Rotating 45° allows switching to another optical interface pair 310. Of course, polygons with more sides can also be used, thus providing more optical interface pairs 310; this application does not impose any limitations on this.
[0065] This configuration offers several advantages. First, the geometric center of the even-sided regular polygon can perfectly coincide with the rotation axis 302, minimizing the eccentricity of the lens body 301 during rotation. This reduces frictional losses between the rotation axis 302 and the bearing, improving rotational lifespan. Second, each optical interface pair 310 of the even-sided regular polygon corresponds to a fixed central angle. Drive components, such as servo motors, can achieve precise switching with a fixed number of steps, improving the accuracy of light output switching and reducing errors. Third, the multiple optical interface pairs 310 correspond precisely to each pair of sides of the regular polygon, enhancing the ease of processing and manufacturing the optical interface pairs 310, reducing costs, and increasing yield. Furthermore, in this embodiment, only the orthographic projections of the third surface 3011 and the fourth surface 3012 in the first direction X are defined as regular polygons. Only the radial contours of the end faces are constrained; the specific shape of the side surfaces (multiple optical interface pairs 310) connecting the two end faces is not constrained. Therefore, the first surface 311 and the second surface 312 of the multiple optical interfaces 310 can be either planar or curved, which is beneficial to further improve the convenience of achieving different light output effects.
[0066] like Figure 7a and Figure 7b As shown, in some embodiments, the plurality of optical interface pairs 310 include a first optical interface pair 310a and a second optical interface pair 310b. The first surface 311a of the first optical interface pair 310a is a smooth plane, and the second surface 312a of the first optical interface pair 310a is formed by splicing together several sub-planes 303, where any two adjacent sub-planes 303 are not coplanar. The first surface 311b of the second optical interface pair 310b is a smooth plane, and the second surface 312b of the second optical interface pair 310b is provided with optical patterns. The optical patterns can be, for example, corn kernel patterns, leather texture patterns, arrayed concave patterns, etc.
[0067] In this embodiment, the plurality of optical interface pairs 310 include a first optical interface pair 310a and a second optical interface pair 310b. The first surface 311a of the first optical interface pair 310a and the first surface 311b of the second optical interface pair 310b have the same optical structure, but the optical structures of their second surfaces (312a, 312b) are different. Thus, up to four light emission effects can be formed.
[0068] It should be noted that the second surface 312a of the first optical interface 310a is composed of several sub-planes 303 spliced together, and any two adjacent sub-planes 303 are not coplanar. That is, the second surface 312a is an irregular surface. When the number of sub-planes 303 increases, for example, to more than or equal to 200, this surface can be called a brilliant diamond surface. When the light from the first lens 200 is finally emitted from the second surface 312a, it can make the signal light module 10 form a brilliant and dazzling lighting effect, enhancing the premium feel of the vehicle.
[0069] The second optical interface, 312b of 310b, features an optical pattern. Depending on the type of optical pattern, various desired light emission effects can be achieved. For example, when the light from the first lens 200 is ultimately emitted from the second surface 312b, a wide-area, glare-free, soft signal light can be achieved. Of course, it's understandable that for specific light emission effects, only corresponding design adjustments to the optical structures of the first surface 311 and the second surface 312 are needed.
[0070] In some embodiments, the first surface 311a of the first optical interface pair 310a is a smooth plane, and the second surface 312a of the first optical interface pair 310a is formed by splicing together a plurality of sub-planes 303, wherein any two adjacent sub-planes 303 are not coplanar; the first surface 311b of the second optical interface pair 310b is provided with optical patterns, and the second surface 312b of the second optical interface pair 310b is the same as the second surface 312a of the first optical interface pair 310a.
[0071] This embodiment exemplifies another structural design for multiple optical interface pairs 310. Specifically, the first surface 311a of the first optical interface pair 310a and the first surface 311b of the second optical interface pair 310b have different optical structures, but their second surfaces (312a, 312b) have the same optical structure. Therefore, up to four light emission effects can be achieved.
[0072] The first optical interface 310a has a smooth surface on the first surface 311a and a brilliant diamond surface on the second surface 312a. When the light from the first lens 200 is finally emitted from the second surface 312a, the signal light module 10 can form a brilliant and dazzling lighting effect, enhancing the vehicle's premium feel.
[0073] The second optical interface features an optical pattern on the first surface 311b of 310b, while the second surface 312a is a brilliant diamond surface. The optical pattern further utilizes light, improving light efficiency. When the light from the first lens 200 finally exits through the second surface 312b, the brilliance and sparkle of the illumination effect are further enhanced, further elevating the vehicle's premium feel.
[0074] In some embodiments, the first surface 311a of the first optical interface pair 310a is formed by splicing together a plurality of sub-planes 303, and any two adjacent sub-planes 303 are not coplanar. The second surface 312a of the first optical interface pair 310a is the same as the first surface 311a of the first optical interface pair 310a. The first surface 311b of the second optical interface pair 310b is provided with a first optical pattern, and the second surface 312b of the second optical interface pair 310b is provided with a second optical pattern.
[0075] This embodiment exemplifies another structural design for multiple optical interface pairs 310. The first surface 311a of the first optical interface pair 310a and the first surface 311b of the second optical interface pair 310b have different optical structures, and their second surfaces (312a, 312b) also have different optical structures. However, the first surface 311a and the second surface 312a of the first optical interface pair 310a have the same optical structure. Therefore, even with different structures for the first and second optical patterns, a maximum of three light emission effects can be achieved.
[0076] The first optical interface has two surfaces, 311a and 312a, that are both brilliant diamond surfaces, which can make the signal light module 10 form a more brilliant and dazzling lighting effect, maximizing the sense of luxury of the vehicle.
[0077] The second optical interface has a first optical pattern on the first surface 311b of 310b and a second optical pattern on the second surface 312a. The structures of the first optical pattern and the second optical pattern can be designed respectively to adapt to the light diffusion effect of different scenarios.
[0078] In some embodiments, the plurality of optical interface pairs 310 include a first optical interface pair 310a and a second optical interface pair 310b. The first surface 311a of the first optical interface pair 310a is the light-incident surface, the second surface 312a of the first optical interface pair 310a is the light-exit surface, and the second surface 312a of the first optical interface pair 310a is provided with a first filter film (not shown in the figure). The first surface 311b of the second optical interface pair 310b is the light-incident surface, the second surface 312b of the second optical interface pair 310b is the light-exit surface, and the second surface 312b of the second optical interface pair 310b is provided with a second filter film (not shown in the figure).
[0079] This embodiment exemplifies another structural design for multiple optical interface pairs 310. In this design, the first optical interface pair 310a has a first surface 311a as its light-incident surface and a second surface 312a as its light-exiting surface, with the light-exiting surface having a first filter film. Similarly, the second optical interface pair 310b has a second filter film on its light-exiting surface (second surface 312b). The first filter film can be, for example, a red filter film, and the second filter film can be, for example, an amber filter film.
[0080] In this design, the first optical interface 310a can generate light of a first specific color, and the second optical interface 310b can generate light of a second specific color. Therefore, without changing the light source 100, two core color light outputs can be achieved, allowing the signal light module 10 to be adapted to at least two different functions of a signal light. For example, when outputting red light, the signal light module 10 functions as a brake light; when outputting amber light, the signal light module 10 functions as a turn signal.
[0081] This configuration achieves the multi-functionality and multi-light output of the traffic light module 10 while reducing cost and size and simplifying the structure.
[0082] In some embodiments, the plurality of optical interface pairs 310 include a first optical interface pair 310a and a second optical interface pair 310b, wherein the first surface 311a and the second surface 312a of the first optical interface pair 310a are configured as a converging lens group, and the first surface 311b and the second surface 312b of the second optical interface pair 310b are configured as a diverging lens group.
[0083] This embodiment exemplifies another structural design for multiple optical interfaces 310. Specifically, the first optical interface 310a's first surface 311a and second surface 312a are constructed as a converging lens group, primarily functioning to converge light rays; for example, its surface shape is a combination of plano-convex, convex-plano, and convex-convex. Conversely, the second optical interface 310b's first surface 311b and second surface 312b are constructed as a diverging lens group; for example, its surface shape is a combination of plano-concave, concave-plano, and concave-concave.
[0084] In this way, the first optical interface 310a can achieve a long-distance directional and concentrated light output effect with high brightness and good penetration; while the second optical interface 310b can achieve a short-distance wide-angle divergent light output effect with a large light output coverage and soft light.
[0085] This configuration achieves the multi-functionality and multi-light output of the traffic light module 10 while reducing cost and size and simplifying the structure.
[0086] like Figure 8 As shown, in some embodiments, there are multiple light sources 100 arranged at intervals along the first direction X, and each light source 100 is provided with a first lens 200 and a second lens 300.
[0087] In this embodiment, the traffic light module 10 is divided into multiple traffic light units, each including a light source 100, a first lens 200, and a second lens 300. This configuration allows for several advantages. First, different traffic light units can have different lighting effects, enhancing the diversity and dynamism of the traffic light module 10's output. The lighting effects of different units can complement each other, resulting in more effective and varied combined lighting effects. Second, different traffic light units can also have identical lighting effects, increasing the final light intensity and coverage area, further improving visibility and output quality. Third, each traffic light unit can independently control the lighting and extinguishing of the light source 100 and the switching of the output effect of the second lens 300. This allows for the combination of dynamic lighting effects, such as flowing water effects, further enhancing the dynamism of the output effect, supporting complex dynamic scenes, and improving the vehicle's premium feel.
[0088] like Figure 1 and Figure 2 As shown, in some embodiments, the surface of the first lens 200 near the light source 100 is a total reflection surface 210 and is provided with a receiving groove 201. The light source 100 is opposite to the opening of the receiving groove 201, and the bottom wall of the receiving groove 201 is provided with a third optical pattern (not shown in the figure).
[0089] The receiving groove 201 can accurately collect the diffused light from the light source 100 and adapt to the light emission pattern of the light source 100, thereby improving the light input efficiency and reducing light loss. By setting a third optical pattern on the bottom wall of the receiving groove 201, it can play a preliminary role in homogenizing the light and improving the uniformity of the incident light. The third optical pattern can be a micro-pattern with a height of 0.02~0.05 mm.
[0090] like Figure 1 and Figure 2 As shown, in some embodiments, the total reflection surface 210 is provided with a fourth optical pattern 211, and the surface of the first lens 200 near the second lens 300 is provided with a fifth optical pattern 212, the fifth optical pattern 212 being configured to provide uniform light.
[0091] By setting a fourth optical pattern 211 on the total internal reflection surface 210, the light incident efficiency is further improved and light loss is reduced. By setting a fifth optical pattern 212 on the light exiting surface of the first lens 200, secondary light homogenization can be achieved, which helps to increase the amount of light entering the second lens 300 and further reduce light loss. Optionally, the fourth optical pattern 211 can be a micro-pattern with a height of 0.02~0.05 mm, and the fifth optical pattern 212 can be a corn kernel pattern with a height of 0.2~0.5 mm.
[0092] Secondly, embodiments of this application provide a vehicle light, including the signal light module 10 described in the first aspect.
[0093] In this way, firstly, a standard optical interface pair 310 can be set on the second lens 300. When this standard optical interface pair 310 is in the output light path of the first lens 200, the signal light module 10 can present a standard signal light optical effect. Then, the surfaces of the other optical interface pairs 310 are designed individually. As a result, the signal light module 10 can also have various other light output effects besides the standard signal light effect, allowing the signal light module 10 to expand from basic driving to more complex application scenarios. This helps to improve the diversity of signal light output effects and the flexibility of the signal lights, thereby enhancing the vehicle's premium feel and user experience.
[0094] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
