Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more specifically, to a multifunctional, reusable lens. Background Technology

[0002] As automotive lighting systems become more intelligent, there is a growing demand for more versatile lighting solutions, moving beyond simply providing illumination. Projection technology is playing an increasingly important role in lighting design. However, the added cost of projection functionality is often prohibitive for mid-to-low-end vehicles. Therefore, finding a solution that integrates multiple functions within existing lighting technologies has become a key focus for OEMs.

[0003] This invention provides a multi-functional integrated lens design that integrates at least two of the following functions: projection, auxiliary low beam, auxiliary high beam, and ambient lighting, thereby reducing projection costs and enriching the user experience. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a multifunctional multiplex lens.

[0005] According to the present invention, a multifunctional multiplex lens includes: a lens body, wherein a first lens light-incident surface, a second lens light-incident surface and a lens light-outcident surface are provided on the lens body; The first lens incident surface can be used as the incident surface for light emitted from the first optical functional light source to enter the lens body; the second lens incident surface can be used as the incident surface for light emitted from the second optical functional light source to enter the lens body; the lens exit surface can be used as a common optical exit surface for the incident light rays from the first lens incident surface and the incident light rays from the second lens incident surface. When the first optical functional light source is used to realize the function of signal light or ambient light, the light emitted by the first optical functional light source is refracted by the light-incident surface of the first lens, then diverges in the lens body, and is refracted by the light-outceasing surface of the lens before being emitted. The emitted light converges on the image-side focal plane to form a converged light spot. After the light spot leaves the image-side focal plane, it diverges and is projected onto the road surface. When the second optical functional light source is used to realize the high beam or low beam function, the light emitted by the second optical functional light source is refracted by the light incident surface of the second lens, then diverges within the lens body, and is refracted by the light exiting surface of the lens before being emitted. The emitted light converges onto the image-side focal plane, forming a converged high beam or low beam spot, thereby forming a high beam or low beam optical path.

[0006] Preferably, when the first optical functional light source is used to realize the function of ambient lighting, the light-incident surface of the first lens is a concave surface with a focal point, and its focal point is a virtual focal point.

[0007] Preferably, when the first optical functional light source is used to realize the functions of signal light and projection, the light-incident surface of the first lens is a convex surface with a focal point, and its focal point is a real focal point.

[0008] Preferably, when the first optical functional light source is used to realize the functions of signal light and projection, the light-incident surface of the first lens has a preset projection pattern.

[0009] Preferably, when the first optical functional light source is used to realize the signal light and projection functions, the preset projection pattern is engraved on the fractal mirror; The split mirror is located between the first optical functional light source and the light incident surface of the first lens.

[0010] Preferably, the split mirror is perpendicular to the parallel incident light emitted by the first optical functional light source.

[0011] Preferably, when the first optical functional light source is used to realize the supplementary lighting function, and the second optical functional light source is used to realize the high beam function or low beam function, the light emitted by the first optical functional light source enters the lens body through the light-incident surface of the first lens, and the light emitted through the light-outcrystal surface of the lens can supplement the light in the area not covered by the high beam or low beam.

[0012] Preferably, the light-emitting surface of the lens is spherical or aspherical.

[0013] Preferably, when the second optical functional light source is used to realize the high beam function or the low beam function, the focal point of the high beam portion or the low beam portion of the lens is located on or near the optical axis.

[0014] Preferably, when the second optical functional light source is used to realize the low beam function, the focal point of the low beam portion of the lens is located on the light incident surface of the second lens.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a lens incident surface partitioning method to separate the incident surface of near beam or high beam from the incident surface of signal lights or ambient lights, making them independent of each other, thereby realizing the multiplexing of multiple functions of a single lens.

[0016] 2. This invention adds projection functionality to conventional optical design schemes by using a lens incident surface partitioning method, thus enriching the user experience.

[0017] 3. By adopting a lens incident surface partitioning method, the various functions are independent of each other and can be freely controlled without interference.

[0018] 4. This invention achieves the switching of multiple projection patterns by using a split-type mirror.

[0019] 5. This invention, through the matching of multiple lens systems and multiple unit modules, can achieve a consistent appearance for signal lights, ambient lights, and high / low beam systems, which is beneficial for design. Attached Figure Description

[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 16 As shown, this embodiment provides a multifunctional multiplexed lens, including: a lens body, on which a first lens light-incident surface 1, a second lens light-incident surface 2, and a lens light-exiting surface 3 are disposed; the first lens light-incident surface 1 can be used as an incident surface for light emitted from a first optical functional light source to enter the lens body; the second lens light-incident surface 2 can be used as an incident surface for light emitted from a second optical functional light source to enter the lens body; the lens light-exiting surface 3 can be used as a common optical exiting surface for the incident light rays from the first lens light-incident surface 1 and the incident light rays from the second lens light-incident surface 2.

[0024] In this embodiment, when the first optical functional light source is used to realize the function of a signal light or an ambient light, the light emitted by the first optical functional light source is refracted by the light-incident surface 1 of the first lens, diverges within the lens body, and is then refracted by the light-outceasing surface 3 of the lens before exiting. The exiting light rays converge onto the image-side focal plane, forming a converged light spot. After the light spot leaves the image-side focal plane, it diverges and is projected onto the road surface. When the second optical functional light source is used to realize the function of a high beam or a low beam, the light emitted by the second optical functional light source is refracted by the light-incident surface 2 of the second lens, diverges within the lens body, and is then refracted by the light-outceasing surface 3 of the lens before exiting. The exiting light rays converge onto the image-side focal plane, forming a converged high beam or low beam light spot, thereby forming a high beam or low beam optical path.

[0025] When the first optical light source is used to realize the function of ambient lighting, the light-incident surface 1 of the first lens is a concave surface with a focal point, and its focal point is a virtual focal point. When the first optical light source is used to realize the functions of signal light and projection, the light-incident surface 1 of the first lens is a convex surface with a focal point, and its focal point is a real focal point. The light-exit surface 3 of the lens is spherical or aspherical.

[0026] In this embodiment, when the first optical functional light source is used to realize the functions of a signal light and a projection, the light-incident surface 1 of the first lens has a preset projection pattern. In another embodiment, when the first optical functional light source is used to realize the functions of a signal light and a projection, the preset projection pattern is engraved on a fractal mirror; the fractal mirror is located between the first optical functional light source and the light-incident surface 1 of the first lens. The fractal mirror is perpendicular to the parallel incident light rays emitted by the first optical functional light source.

[0027] In another embodiment, when the first optical functional light source is used to realize the supplementary light function and the second optical functional light source is used to realize the high beam function or low beam function, the light emitted by the first optical functional light source enters the lens body through the light-incident surface 1 of the first lens, and the light emitted through the light-outcrystal surface 3 of the lens can supplement the light in the area not covered by the high beam or low beam.

[0028] In this embodiment, when the second optical functional light source is used to realize the high beam function or the low beam function, the focal point of the high beam portion or the low beam portion of the lens is located on or near the optical axis. In another embodiment, when the second optical functional light source is used to realize the low beam function, the focal point of the low beam portion of the lens is located on the light-incident surface 2 of the second lens.

[0029] Example 2 Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0030] This embodiment provides a multi-functional lens design, which includes a lens consisting of a first lens light-incident surface 1, a second lens light-incident surface 2, and a lens light-exiting surface 3. The first lens light-incident surface 1 is the receiving surface when light for signal lights or ambient lights enters the lens; the second lens light-incident surface 2 is the receiving surface when light for high beam or low beam functions enters the lens; and the lens light-exiting surface 3 is the optical exiting surface shared by all functions.

[0031] The working principle of ambient lights or signal lights is as follows: light rays emitted from an off-axis point are refracted by the first lens's incident surface 1, diverge inside the lens, and are then refracted again by the lens's exit surface before exiting. The working principle of signal lights or projection lights is as follows: light rays emitted from an off-axis point at infinity are always parallel to each other. These parallel rays are refracted by the first lens's incident surface 1, exit through the lens's exit surface 3, and converge onto the image-side focal plane, forming a converging light spot. After leaving the focal plane, the light spot diverges and is projected onto the road surface.

[0032] The working principle of high beam headlights is as follows: light rays emitted from object point A on the axis are received and refracted by the light-incident surface 2 of the second lens, and then exit through the light-out surface of the lens, forming an image on the image-side focal plane. The light spot that converges on the image-side focal plane is the high beam spot. A schematic diagram of the light rays is shown below. Figure 6 As shown. The working principle of low beam headlights is similar to that of high beams. The low beam beam path is obtained by mirroring the high beam beam along the optical axis.

[0033] More specifically, such as Figure 1As shown, light rays emitted from an object point at infinity off-axis are always parallel to each other and make a certain angle with the optical axis. In the figure, the light rays enter the lens system at an angle ω with the optical axis and converge on the image-side focal plane to form image point A'. The magnitude of ω represents the angular distance of the off-axis object point from the optical axis. When ω approaches 0, the off-axis object point coincides with the on-axis object point; as shown... Figure 2 As shown, light rays emitted from an object point on the axis are incident parallel to the incident surface of the lens. In order to... Figure 1 To obtain the image A' of the on-axis object point on the image-side focal plane, the incident plane 1 of the first lens needs to be deflected so that the image-side focal plane of the entire lens system is aligned with the focal plane of the object. Figure 1 The focal plane remains consistent.

[0034] More specifically, a lens has an incident surface and an exit surface. An on-axis object point imaged through the lens is equivalent to an off-axis object point imaged through a birefringent surface. The birefringent surfaces are the first incident surface (1) and the exit surface (3) of the lens. For example... Figure 2 As shown, parallel rays emitted from an on-axis object point are incident on the first lens incident surface 1 (first refractive surface). The refracted rays converge to form an image point, which is the object point when the light rays pass through the lens exit surface 3. Therefore, we can also consider the area illuminated by the parallel rays emitted from the on-axis object point passing through the first lens incident surface 1 as the area to be projected. This area will be imaged on the image-side focal plane through the lens exit surface 3 (second refractive surface), simplifying the above-mentioned area to be projected into a planar view. Figure 4 As shown, a perpendicular line is drawn from the highest point A of the projected area, perpendicular to the optical axis. This line intersects the optical axis at point B. The image A'B' formed by the refraction of line segment AB through the lens's exit surface 3 is perpendicular to the optical axis BOB'. The ray AC emitted from the off-axis object point A and passing through the center C of the sphere must pass through point A', because AC is equivalent to the optical axis of the off-axis object point A. Let r represent the radius of the lens's exit surface. Figure 4 Let AB = y, A'B' = y', since ABC is similar to If A'B'C', then: (1-1) In the above formula, β is the ratio of the image size to the object size, known as the transverse magnification. In paraxial optical systems, the Labe invariant Q in object space and image space is equal, but varies with the position of the conjugate point, as shown in the following formula: (1-2) Using equation (1-2), we can convert the result to: (1-3) According to (1-3), we can conclude that: (1-4) As shown in formula (1-4), in a vehicle lighting system, y' represents the installation height of the headlight, and n and n' represent the refractive index of the medium in the object-image space, respectively. l' represents the distance from the lens vertex to the image-side focal plane, which in a vehicle lighting system represents the distance between the lens vertex and the detection screen. In a vehicle lighting system, y', n, n', and l' can all be known quantities, so y is positively correlated with l, and determining l determines the magnitude of y. Using the above formula, the approximate height of the incident light surface required for imaging on a known detection screen can be roughly estimated.

[0035] More specifically, users are more concerned with the image spots on the ground. This is specifically defined as where the light spots begin and end. For example... Figure 5 As shown, take point B at the bottom edge of the pattern to be projected. The light ray emitted from B, passing through the center C of the lens, forms point B' on the image-side focal plane. Extend line segment BB' to point B'' and intersect the ground at B''. At this point, line segment A'B'' is the projection of line segment AB onto the ground. Draw a perpendicular line from point B to the optical axis and compare it with point E. Draw a perpendicular line from B'' to the optical axis and compare it with point F''. Let BE = y, B'E' = y', and F'B'' = y''. Since... BEC is similar to If A'F'C', then: (1-5) because BEC is similar to B'E'C', then: (1-6) From equations (1-5) and (1-6), we can obtain: (1-7) In equation (1-7), -y'' is equivalent to y' in equation (1-4). Using the above formula, the arithmetic relationship between the height y of point B and the distance l can be obtained, thereby calculating the lower boundary position of the pattern to be projected and determining the required longitudinal range for projection. Conversely, by determining the values ​​of the height y and distance l of points A and B, the lateral distance of the ground projection can also be calculated.

[0036] Furthermore, when implementing the ambient lighting function, the first lens incident surface 1 is a concave surface with a focal point, and its focal point is a virtual focal point.

[0037] Furthermore, when realizing the signal light and projection functions, the first lens incident surface 1 is a convex surface with a focal point, and its focal point is a real focal point.

[0038] Furthermore, when realizing the signal light and projection functions, the light-incident surface 1 of the first lens can have a pattern that needs to be projected.

[0039] Furthermore, when realizing the signal light and projection functions, the light-incident surface 1 of the first lens can have a pattern that needs to be projected.

[0040] Furthermore, when implementing the signal light and projection functions, the light-incident surface 1 of the first lens does not have complex patterns such as logos engraved on it; the pattern to be projected is engraved on the split mirror.

[0041] Furthermore, when realizing the signal light and projection functions, the patterned fractal mirror is placed between the light source system and the light-incident surface 1 of the first lens.

[0042] Furthermore, when implementing the signal light and projection functions, the patterned fractal mirror remains perpendicular to the parallel incident light emitted by the light source system.

[0043] Furthermore, if pattern projection is not required, the light emitted through the light-incident surface 1 and light-exit surface 3 of the first lens can supplement the light in areas that cannot be covered by near and far light.

[0044] Furthermore, the light-emitting surface 3 of the lens can be customized according to actual needs. That is, the light-emitting surface 3 of the lens can be spherical or aspherical, and the spherical surface can also be a plane with an infinite radius.

[0045] Furthermore, the light-incident surfaces 1 and 2 of the first and second lenses have a master-slave relationship with the light-outceasing surface 3. That is, when the light-outceasing surface 3 is adjusted, the light-incident surfaces 1 and 2 need to be adjusted in coordination with the light-outceasing surface 3.

[0046] Furthermore, the focal point A of the near-light portion of the lens is jointly determined by the light-incident surface 2 and the light-exit surface 3 of the second lens. When the radius of the light-incident surface 2 of the second lens is infinitely large, the light-incident surface 2 of the second lens becomes a large flat surface, and at this time, the focal point A of the lens is determined by the light-exit surface 3 of the lens.

[0047] Furthermore, the focal point A of the lens's near and far beams can be on the optical axis or near the optical axis, which is beneficial for adjusting the light pattern of near and far beams.

[0048] Furthermore, the focal point A of the near-light portion of the lens can also be located on the light-incident surface 2 of the second lens.

[0049] Example 3 Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1 and Embodiment 2.

[0050] This embodiment provides an imaging lens with an aperture of 30mm x 20mm (other aperture sizes may be used in other embodiments), comprising a first light-incident surface 1, a second light-incident surface 2, and a light-outcident surface 3. The lens can simultaneously function as a traffic light and a high beam. The first light-incident surface 1 is the light-incident surface for the traffic light function, with a focal length of 50mm. The second light-incident surface 2 is a plane with an infinite radius, and the light-outcident surface has a focal length of 70mm. Its optical path for the traffic light function is as follows: Figure 7 As shown, the light rays emitted from the off-axis object point are refracted by the first lens incident surface 1, diverge inside the lens, and are then refracted by the lens exit surface 3 before exiting.

[0051] More specifically, the design purpose of this signal light is to evenly illuminate the imaging lens, achieving uniform lighting of the exterior. In this mode, the signal light illuminates and flashes in response when the owner wakes the vehicle. More specifically, the light source of the signal light can be RGB, as long as it complies with regulatory requirements.

[0052] like Figure 7 As shown in the diagram, the light-incident surface in this embodiment is divided into several small curved surfaces. To make the lighting effect softer, the spherical surface of the first lens's light-incident surface 1 can be divided into several small curved surfaces. Each small curved surface has a divergence angle in both the horizontal and vertical directions. In this way, the light rays refracted by the light-incident surface propagate more freely inside the lens, resulting in a better lighting effect. The front view of the first lens's light-incident surface 1 is shown in the diagram. Figure 9 As shown. Figure 10 This diagram illustrates the distribution of light on the light-emitting surface of the lens in this embodiment. It shows that the light does not concentrate or disperse in any particular area on the light-emitting surface, but is evenly dispersed on the light-receiving surface, achieving the goal of uniformly illuminating the lens. Taking an LED light source as an example, the central light emission direction of the ambient light must be coaxial with the optical axis of the light-receiving surface 1 of the first lens for maximum efficiency. Figure 11 This refers to the diffused light spot on the screen from the signal light or ambient light in this embodiment. The optical path of the high beam is as follows: Figure 12 As shown, the light rays emitted from focal point 2 are received and refracted by the light-incident surface 2 of the second lens, and then exit from the light-out surface of the lens, forming an image on the image-side focal plane. The light spot that converges on the image-side focal plane is the far-beam light spot.

[0053] Example 4 Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1 and Embodiment 2.

[0054] This embodiment provides an imaging lens with an opening of 15mm x 10mm (other opening sizes may be used in other embodiments), comprising a first light-incident surface 1, a second light-incident surface 2, and a light-outceasing surface 3. The lens can simultaneously function as a projector lamp and a high-beam. The first light-incident surface 1 serves as the light-incident surface for the signal lamp function, with a focal length of 30mm. The second light-incident surface 2 is a plane with an infinite radius, and the light-outceasing surface has a focal length of 25mm. The optical path is as follows... Figure 13 As shown, light rays emitted from an object point at infinity off-axis are always parallel to each other. After passing through the fractal lens, the parallel light rays are refracted by the first lens's entrance surface 1, exit through the lens's exit surface 3, and converge on the image-side focal plane. The converged light spot then diverges again and is projected onto the ground.

[0055] More specifically, a fractal mirror is a carrier for the pattern to be projected. It can be engraved with specific symbols, patterns, logos, and other shapes that need to be projected. Except for the shape, which is translucent, the other areas are opaque. Figure 14 Two types of graphics are given on a fractal mirror: a straight arrow and a right-passing arrow. Figure 15 and Figure 16 These are schematic diagrams showing the light spots on the detector when the high beam is activated, specifically the straight-ahead arrow and the right-overtaking arrow.

[0056] More specifically, in this embodiment, both the signal lights and the projection lights can be controlled independently, enabling them to be lit individually.

[0057] More specifically, a solution that integrates high beams and traffic lights or ambient lights can be rotated 180° along the horizontal axis to achieve the function of illuminating low beams while simultaneously using ambient lights or traffic lights.

[0058] This invention divides the lens into two light-receiving areas: a projection area and a high / low beam area, which are independent of each other and their surface size is adjustable. This invention can integrate at least two functions: high beam, low beam, projection, auxiliary high / low beam, signal light, and ambient light. This invention enables a lighting system with multiple functions that can be independently controlled. This invention can supplement light in areas not covered by the high beam (1 meter in front of the vehicle) and can customize projection patterns, logos, and other elements. When the distance from the light source to the vertex of the lens's outer surface is greater than 50mm, different patterns can be projected onto the same system by switching the split-type mirror.

[0059] In this embodiment, the light source is a surface-mount LED, which is integrated on the PCBA or on the heat sink and connected to the PCB board via metal wires. In other embodiments, other types of light sources can be selected according to actual needs.

[0060] This invention can be configured to generate multiple light distributions of different types, each of which can be any of the following: low beam lighting, high beam lighting, adaptive low beam lighting, ADB high beam lighting, corner fog light lighting, urban road mode lighting, rural road mode lighting, highway mode lighting, curve mode lighting, rain and fog mode lighting, position signal lights, turn signal lights, daytime running lights, welcome lights, ambient lights, etc.

[0061] The present invention divides the lens into two light-incident areas: a light-incident area for projection and a light-incident area for near and far light. The two areas are independent of each other and their surface size is adjustable.
