Description

Technical Field

[0001] This disclosure relates to an optical lens system for vehicle lighting applications (such as vehicle lighting units), wherein the system includes a lens body and a light source unit configured to emit light to the lens body. The lens body includes an incident surface arranged to receive incident light from the light source unit, an exiting surface configured to emit light received from the first light source unit via the first incident surface, and a light impacting surface. The light impacting surface and the exiting surface are arranged opposite to each other and connected via the first incident surface. The light impacting surface includes at least one first optical region configured to redirect incident light from the first incident surface to the exiting surface, wherein the at least one first optical region is formed by a plurality of optical elements. The optical elements are arranged as recesses in the light impacting surface of the lens body. This disclosure also relates to a vehicle including an optical lens system, and a vehicle lighting unit including an optical lens system. Background Technology

[0002] Vehicle lighting systems, which utilize vehicle lighting units such as taillights and position lights, are used on vehicles to meet safety regulations. Vehicle lighting systems or units typically include optical lens systems for establishing desired light output in various applications. Lighting systems or units are often integrated into the vehicle's design to achieve an attractive appearance and establish specific vehicle identification, for example, through the design of light patterns. Optical lens systems are used to guide light from a source to a luminescent surface, such as taillights, position lights, ambient lights, general lighting features, or similar vehicle lighting structures. In today's vehicle applications, there are high demands on the aesthetic appearance, compact design, and luminous performance required to meet safety regulations for lighting structures. A common challenge in designing vehicle lighting structures is achieving a uniform or homogeneous light pattern on the luminescent surface and a uniform or substantially uniform light distribution from the luminescent surface when viewed from different angles. This is particularly complex when the luminescent surface has a non-planar structure. Therefore, an improved vehicle lighting system is needed. Summary of the Invention

[0003] The purpose of this disclosure is to provide an optical lens system for vehicle lighting applications that avoids the aforementioned problems, a vehicle including the optical lens system, and a vehicle lighting unit including the optical lens system. This purpose is achieved at least in part by the features of the independent claims. The dependent claims include further improvements to the optical lens system and the vehicle lighting unit.

[0004] This disclosure relates to an optical lens system for vehicle lighting applications, wherein the system includes a lens body and a first light source unit configured to emit light to the lens body. The lens body includes a first incident surface arranged to receive incident light from the first light source unit, an exiting surface configured to emit light received from the first light source unit via the first incident surface, and a light-affected surface. The light-affected surface and the exiting surface are arranged opposite to each other and connected via the first incident surface. The light-affected surface includes at least one first optical region configured to redirect incident light from the first incident surface to the exiting surface, wherein the at least one first optical region is formed by a plurality of optical elements. The optical elements are arranged as recesses in the light-affected surface of the lens body. The optical elements are configured to have a frustoconical section disposed within the lens body and connected to the light-affected surface, and a circular cap section disposed within the lens body and connected to the frustoconical section. The bottom surface of the circular cap section coincides with the top surface of the frustoconical section. The truncated cone segment includes an outer surface and a bottom surface, and the circular cap segment includes an outer surface, and the cross-sectional transition between the outer surface of the truncated cone segment and the outer surface of the circular cap segment is non-linear.

[0005] The advantage of these features is that, through the design of the optical elements within the lens body, the optical lens system provides a compact structure that meets safety regulations and demanding lighting aesthetics. The system's construction enables the creation of a uniform or substantially uniform light pattern on the light-emitting surface, and a uniform or substantially uniform light distribution with no visible light intensity fluctuations from the light-emitting surface when viewed from different angles. The truncated cone section reflects the incident light from the light source unit, while the rounded cap section directs the light towards the light-emitting surface for a uniform light distribution from the lens body. The proportional balance between the truncated cone section and the rounded cap section results in a balance between the light intensity and the uniformity of the light distribution from the lens body. This solution provides an optical system that can be widely used in lenses, internal lenses, and optical elements in all interior and exterior lighting applications in vehicles, achieving a good uniform appearance and sufficient luminous efficacy to meet legal requirements. The system can be used in various lighting vehicle components, such as taillights, position lights, ambient lights, and general lighting features, and through the arrangement of the optical elements, the system can be made virtually invisible when not emitting light. This solution will greatly assist in the design of lighting applications, and the lens body can be scalably manufactured for different lighting applications. The lens body with optical elements can be designed to have a perspective effect for attractive vehicle lighting designs, and the size of the recesses of the optical elements in the light-affected surface forming the lens body can be varied to achieve different perspective effects. Smaller recesses will create a better perspective effect for the lens body. The system also reduces the number of components used in the vehicle, thereby reducing costs.

[0006] According to one aspect of this disclosure, the cross-sectional transition between the outer surfaces of the truncated cone segment and the outer surfaces of the circular cap segment at the transition point is non-linear, wherein the bottom surface of the circular cap segment coincides with the top surface of the truncated cone segment at the transition point. This non-linear cross-sectional transition of the optical element provides a redirection of incident light to establish a desired uniform light pattern in the emitting surface. This uniform light distribution prevents fluctuations in the intensity of visible light from the emitting surface when viewed from different angles.

[0007] According to another aspect of this disclosure, the cross-sectional transition between the outer surface of the truncated cone section and the tangent forms an outer transition angle of less than 180 degrees. For an optical element configuration having a truncated cone section and a circular cap section, a suitable outer transition angle is greater than 0 degrees and less than 180 degrees, and depends on the configuration of the truncated cone section and the circular cap section.

[0008] According to one aspect of this disclosure, the outer transition angle is in the range of 3 degrees to 177 degrees, preferably in the range of 113 degrees to 177 degrees. These ranges provide efficient light distribution characteristics. It has been found that the range of 113 degrees to 177 degrees is suitable for lens bodies made of various materials, such as polymethyl methacrylate (PMMA), polycarbonate (PC), mixtures of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), silicone plastics, or any other suitable plastic or other material with transparent properties. If a flexible material, such as silicone plastic, is used, the lens body can be formed into the desired shape.

[0009] According to another aspect of this disclosure, the bottom surface of the frustum section is arranged to be connected to the light-affected surface. From the perspective of light distribution and manufacturing, it is appropriate for the bottom surface of the frustum section to be connected to the light-affected surface.

[0010] According to one aspect of this disclosure, the circular cap segment is constructed as a spherical cap segment. The spherical cap segment can provide efficient distribution of incident light and has a simple structure.

[0011] According to another aspect of this disclosure, the truncated cone section has a circular bottom surface and a circular top surface. The circular top surface is arranged within the lens body. The circular structure has been shown to be efficient for uniform light distribution within the lens body and to simplify the structure during lens body manufacturing.

[0012] According to one aspect of this disclosure, the optical element is configured to redirect incident light from a first optical flow direction to a second optical flow direction. Therefore, the optical element redirects incident light from the incident surface to the exiting surface.

[0013] According to another aspect of this disclosure, the system includes a first light source and a second light source. The lens body includes a first light-incident surface for the first light source unit and a second light-incident surface for the second light source unit, wherein the first and second light-incident surfaces are arranged opposite to each other and connected by a light-affected surface and a light-exiting surface. The light-affected surface includes a first optical region and a second optical region formed by a plurality of optical elements. Through this arrangement, the optical regions can be configured for efficient light distribution with attractive light pattern designs.

[0014] According to another aspect of this disclosure, a first optical region is arranged in relation to a first light source unit, and a second optical region is arranged in relation to a second light source unit. The arrangement of the respective optical regions enables efficient redistribution of incident light from the corresponding light source unit to obtain a uniform light distribution from the lens body.

[0015] According to one aspect of this disclosure, a first optical region of the light-affected surface is defined by a plurality of optical elements, wherein the plurality of optical elements in the first optical region are arranged in a hexagonal pattern. Alternatively, a first optical region and a second optical region of the light-affected surface are defined by a plurality of optical elements, wherein the plurality of optical elements in the first optical region and the second optical region are arranged in a hexagonal pattern. These features enable the provision of optical patterns on lenses, internal lenses, and optical elements that can be widely applied in all interior and exterior lighting applications in automobiles, wherein a good, uniform appearance with sufficient luminous efficacy to meet legal requirements is achieved.

[0016] According to another aspect of this disclosure, the hexagonal pattern is formed by pairs of optical elements. This pairing creates a visually appealing design for the optical region, where the paired optical elements further ensure efficient light distribution.

[0017] According to another aspect of this disclosure, the hexagonal pattern is formed by a plurality of optical elements arranged in a repeating continuous hexagonal pattern, which provides efficient redistribution of incident light.

[0018] According to one aspect of this disclosure, each hexagon in the hexagonal pattern includes a non-filled area. The non-filled area is configured to create a perspective effect within the lens body. This perspective effect further enhances the attractive design of the system. When the lens body is not emitting light, the perspective effect can be used to create an aesthetically pleasing design effect for the system in external or internal lighting structures. The dimensions of the recesses in the light-affected surfaces forming the lens body can be varied to achieve different perspective effects. Smaller recesses will create a better perspective effect for the lens body. Two or more lens bodies can be arranged sequentially to create continuous three-dimensional light patterns and / or animated three-dimensional light patterns, and this can be achieved through the perspective effect of the lens bodies.

[0019] According to another aspect of this disclosure, the lens body includes a first buffer zone between a first incident surface and a first optical region. Alternatively, the lens body includes a first buffer zone between the first incident surface and the first optical region and a second buffer zone between a second incident surface and a second optical region. The buffer zones ensure that incident light is uniformly diffused within the lens body before being redirected in one or more optical regions.

[0020] According to another aspect of this disclosure, each light source unit includes multiple light sources. The multiple light sources are used to ensure the correct light input intensity entering the lens body and to establish a uniform light distribution within the lens body.

[0021] This disclosure also relates to vehicles that include the optical lens system described above.

[0022] This disclosure also relates to vehicle lighting units that include one or more optical lens systems as described above.

[0023] According to another aspect of this disclosure, the vehicle lighting unit includes two or more optical lens systems, wherein the lens bodies of these optical lens systems are arranged sequentially and configured to create a continuous three-dimensional light pattern and / or an animated three-dimensional light pattern.

[0033] The various aspects of this disclosure will now be described in conjunction with the accompanying drawings, in order to describe and not limit the disclosure, wherein like reference numerals denote like elements, and variations of the described aspects are not limited to the embodiments specifically shown, but rather to other variations applicable to the disclosure.

[0034] Figures 1a to 1b An embodiment of an optical lens system S for vehicle lighting applications is schematically illustrated, wherein the optical lens system can be used in a vehicle lighting unit. The optical lens system S includes a lens body 1 and a first light source unit 2a configured to emit light into the lens body 1. The lens body 1 includes a first light-incident surface 3a arranged to receive incident light from the first light source unit 2a, a light-exit surface 5 configured to emit light received from the first light source unit 2a through the first light-incident surface 3a, and a light-affecting surface 4. Figures 1a to 1b As shown, the light-affected surface 4 and the light-exiting surface 5 are arranged opposite to each other and connected by a first light-incident surface 3a. The light-affected surface 4 is arranged to redirect incident light from the first light-incident surface 3a to the light-exiting surface 5, which will be further described below. In the illustrated embodiment, the first light-incident surface 3a is arranged as the upper surface of the lens body 1, and the light-affected surface 4 and the light-exiting surface 5 are connected by two oppositely arranged side surfaces 3c. A lower surface 3d arranged opposite to the first light-incident surface 3a further connects the light-affected surface 4 and the light-exiting surface 5. "Upper" and "lower" as used herein refer to... Figures 1a to 1b The orientation of the surfaces is shown. It should be understood that the surfaces can be oriented in other ways if desired. The two side surfaces 3c and the lower surface 3d are configured as flat surfaces. However, the two side surfaces 3c and the lower surface 3d can have different shapes and can be configured as non-flat surfaces. If desired, the two side surfaces 3c and the lower surface 3d can also be masked or hidden in the vehicle lighting structure to prevent unwanted light emission from the lens body 1.

[0035] Lens body 1 may, for example, have the following characteristics: Figures 1a to 1bThe parallelepiped structure shown has a height dimension D1, a width dimension D2, and a length dimension D3. The length dimension D3 can be varied, for example, to achieve different surface areas of the light-emitting surface 5. For instance, if a predetermined height dimension D1 is used in a specific lens body structure, and the length dimension D3 is varied for different designs of the optical lens system S, the light intensity and structure of the first light source unit 2a to achieve the desired characteristics can depend on the length dimension D3. However, it should be understood that, depending on the design of the vehicle or vehicle components, the system can be configured to have other suitable shapes, such as, for example, curved or irregular shapes.

[0036] The light-affected surface 4 includes at least one first optical region 6a formed by a plurality of optical elements 7. The at least one optical region 6a is configured to redirect incident light from the first incident surface 3a to the exit surface 5.

[0037] exist Figures 1a to 1b In the illustrated embodiment, the light-affected surface 4 includes a first optical region 6a formed by a plurality of optical elements 7. The first light source unit 2a can be of any type or design, and suitably includes a plurality of light sources 10 arranged at a distance from each other. Figure 1a The diagram shows three light sources 10, but depending on the design of the optical lens system S, the first light source unit 2a may include only one light source 10, or optionally include two or more light sources 10.

[0038] like Figure 1b As schematically indicated by the arrow, the light source 10 emits light into the first incident surface 3a of the lens body. The first optical region 6a of the lens body 1, having a plurality of optical elements 7, is arranged to redirect incident light from the first light source unit 2a, which has the light source 10, from a first optical flow direction X to a second optical flow direction Y. In this way, the optical elements 7 of the lens body 1 are configured to redirect incident light from the first optical flow direction X to the second optical flow direction Y, wherein the second optical flow direction Y is arranged at an angle relative to the first optical flow direction X. The lens body 1 is arranged after the first light source unit 2a along the first optical flow direction X. The lens body 1 is designed and constructed such that a uniform or substantially equivalent light distribution of the light from the light source 10 of the first light source unit 2a emitted through the light exiting surface 5 is achieved. As described above, the lens body 1 includes a first incident surface 3a and a light exiting surface 5. The first incident surface 3a is arranged to receive incident light from the light source 10. The light-emitting surface 5 is arranged to emit light received from the light source 10 through the first light-incident surface 3a. The light-emitting surface 5 distributes the emitted light, for example, to the exterior of the vehicle or to the interior compartment of the vehicle. If desired, the optical lens system S may also include a protective sheet, such as an outer lens, covering the light-emitting surface 5.

[0039] The light emitted from the multiple light sources 10 of the first light source unit 2a is redirected from the first optical flow direction X to the second optical flow direction Y in the lens body 1, and the compact design of the optical lens system S is achieved by the redirection of the optical flow.

[0040] Each light source 10 is appropriately arranged at a small distance from the first incident light surface 3a, for example, as Figures 1a to 1b As shown. Therefore, as Figure 1b As shown, a small gap G is provided between each light source 10 and the first light-incident surface 3a. In an alternative embodiment (not shown), the light source 10 can be arranged to directly contact the first light-incident surface 3a. In another alternative embodiment, such as... Figure 7 As shown, the light source 10 is embedded in the first light-incident surface 3a. Figure 7 The optical lens system S shown has similar characteristics to... Figures 1a to 1b The optical lens system shown is constructed as follows. Instead of multiple light sources, one or more light guides or similar arrangements can be used as the first light source unit 2a. Using light guides can reduce the number of light sources used.

[0041] As described above Figures 1a to 1b The first optical region 6a is formed by a plurality of optical elements 7, and in such a way that the extension of the first optical region 6a is defined by these optical elements 7. The optical elements 7 are arranged as recesses I in the light-affected surface 4 of the lens body 1, and thus each optical element 7 forms a cavity in the lens body 1. When molding the lens body 1, the recesses I in the lens body 1 formed by the optical elements 7 can be realized, and then the mold used is prepared (pre-processed to have) the optical element structure.

[0042] like Figures 1a to 1b As shown, the first optical region 6a is arranged in relation to the first light source unit 2a, and in this embodiment, the lens body 1 includes a first buffer zone 11a between the first light-incident surface 3a and the first optical region 6a. The first buffer zone 11a is arranged to ensure that incident light from the light source 10 is uniformly dispersed in the lens body 1 before being redirected in the first optical region 6a. The region between the first light-incident surface 3a and the first optical region 6a defines the first buffer zone 11a, and the size and shape of the first buffer zone 11a can vary depending on the design of the lens body 1. The first optical region 6a and the first buffer zone 11a can have any suitable regular or irregular shape.

[0043] exist Figures 1a to 1b In the illustrated embodiment, the first optical region 6a of the light-affected surface 4 is defined by a plurality of optical elements 7, and the plurality of optical elements 7 in the first optical region 6a are arranged in a hexagonal pattern H. Figure 5The hexagonal pattern is shown in more detail below. The hexagonal pattern H is formed by pairs of optical elements 7, and as shown... Figure 1a and Figure 5 As shown, the hexagonal pattern H is formed by a plurality of optical elements 7 arranged in a repeating, continuous hexagonal pattern. The hexagonal pattern H means that the optical elements 7 form a pattern consisting of a plurality of adjacent hexagons with six sides and six corners, and wherein, as shown... Figure 5 As schematically shown, imaginary straight lines connecting two optical elements forming a hexagon constitute the sides of the hexagon. The optical hexagonal pattern H is suitable for various lighting applications requiring sufficient luminous efficacy to meet legally mandated uniform appearance. Paired arrangements create a visually appealing optical zone design, and testing has shown that paired optical elements guarantee efficient light distribution. The paired optical elements 7 forming the hexagonal pattern H can be arranged to form regular hexagons, where the hexagons are equilateral and equiangular, or irregular alternative hexagons.

[0044] exist Figure 5 In the diagram, first optical element 7a, second optical element 7b, third optical element 7c, fourth optical element 7d, fifth optical element 7e, and sixth optical element 7f form a hexagon H1. The shape of hexagon H1 is illustrated by the imaginary dashed lines. The first imaginary dashed line L1 connects the first optical element 7a and the second optical element 7b; the second imaginary dashed line L2 connects the second optical element 7b and the third optical element 7c; the third imaginary dashed line L3 connects the third optical element 7c and the fourth optical element 7d; the fourth imaginary dashed line L4 connects the fourth optical element 7d and the fifth optical element 7e; the fifth imaginary dashed line L5 connects the fifth optical element 7e and the sixth optical element 7f; and the sixth imaginary dashed line L6 connects the sixth optical element 7f and the first optical element 7a. Each hexagon in the hexagonal pattern H includes a non-filled region 12, which is configured to create a perspective effect within the lens body 1. The non-filled region 12 refers to an area that does not contain any optical element 7. Figure 5The unfilled area 12 shown is surrounded by the first to sixth optical elements 7a to 7e, and the hexagonal pattern comprises multiple hexagons with unfilled areas 12. The unfilled areas 12 in each hexagon of the hexagonal pattern H are arranged as non-interfering areas, and when the lens body 1 is made of a transparent material, the lens body 1 can be seen through the unfilled areas 12. The optical elements 7 are smaller relative to the unfilled areas 12, thus creating a perspective effect, thereby achieving a visually attractive design for the optical lens system S and simultaneously achieving efficient light distribution. The perspective effect gives the optical lens system S a three-dimensional appearance, and graphic elements can be arranged, for example, behind the lens body 1 to achieve an attractive design. The size of the recesses I in the light-affected surface 4 forming the lens body 1 can be varied to obtain different perspective effects. Smaller recesses I will create a better perspective effect for the lens body 1. Two or more lens bodies 1 can be arranged sequentially to create continuous three-dimensional light patterns and / or animated three-dimensional light patterns, and this is achieved through the perspective effect of the lens bodies 1 and by continuously activating different light sources of the combined optical lens system S.

[0045] like Figure 3 and 4 As shown in more detail, the optical element 7 is configured to have a frustoconical section 8 disposed within the lens body 1 and connected to the light-affected surface 4, and a circular cap section 9 disposed within the lens body 1 and connected to the frustoconical section 8.

The circular cap section 9 is arranged to efficiently propagate light toward the light-emitting surface 5 to obtain a uniform light distribution from the lens body 1, for establishing the main optical flow output in the second optical flow direction Y. The ratio between the truncated cone section 8 and the circular cap section 9 balances the light intensity and the uniformity of the light distributed from the lens body 1.

[0046] The truncated cone segment 8 is defined as a portion of a cone bounded by two planes, wherein the cone has a three-dimensional geometry that tapers gradually from a flat base to a apex. The base of the cone can be any closed one-dimensional shape, such as a circle.

However, it should be understood that in other embodiments not shown, the truncated cone segment 8 may have other configurations, such as, for example, a truncated cone segment based on an oblique cone.

[0048] The circular cap section 9 is defined by the bottom surface 9 BS and outer surface 9 OS The defined volume, of which the outer surface 9 OS It has a circular cross-sectional shape. Therefore, the outer surface 9 OS It has a curved cross-sectional shape without sharp angles. The cross-sectional shape refers to the shape perpendicular to the base. BS The shape is arranged in a plane, wherein the plane extends through the bottom surface 9. BS .

[0049] exist Figures 1a to 1b , Figure 3 , Figure 4 and Figure 6 In the illustrated embodiment, the circular cap segment is configured as a spherical cap segment, and is therefore based on a sphere. The bottom surface 9 of the spherical cap segment... BS It is circular, and its shape and size correspond to the top surface 8 of the truncated cone segment 8. TS However, it should be understood that in other embodiments not shown, the circular cap segment 9 may have other constructions.

[0050] In the following description, the optical element 7 will be described in conjunction with the illustrated embodiment, wherein the circular cap section 9 is arranged as a spherical cap section.

[0055] exist Figures 2a to 2b In the alternative embodiment shown, the optical lens system S includes a first light source 2a and a second light source 2b. The lens body 1 includes a first light-incident surface 3a for the first light source unit 2a and a second light-incident surface 3b for the second light source unit 2b. The first light-incident surface 3a and the second light-incident surface 3b are arranged opposite to each other and connected by a light-affected surface 4 and a light-emitting surface 5. The light-affected surface 4 includes a first optical region 6a and a second optical region 6b formed by a plurality of optical elements 7. Figures 2a to 2b As shown, the first optical region 6a is arranged in relation to the first light source unit 2a, and the second optical region 6b is arranged in relation to the second light source unit 2b.

[0056] A first incident light surface 3a is arranged to receive incident light from a first light source unit 2a, and a second incident light surface 3b is arranged to receive incident light from a second light source unit 2b. An exiting light surface 5 is configured to emit light received from the first light source unit 2a via the first incident light surface 3a, and to emit light received from the second light source unit 2b via the second incident light surface 3b. Figures 2a to 2b As shown, the light-affected surface 4 and the light-exiting surface 5 are arranged opposite each other and connected by a first light-incident surface 3a and a second light-incident surface 3b. The light-affected surface 4 is arranged to redirect incident light from the first light-incident surface 3a and the second light-incident surface 3b toward the light-exiting surface 5, which will be further described below. In the illustrated embodiment, the first light-incident surface 3a is arranged as the upper surface of the lens body 1, and the second light-incident surface 3b is arranged as the lower surface of the lens body 1. The light-affected surface 4 and the light-exiting surface 5 are connected by two opposing side surfaces 3c. "Upper" and "lower" as used herein refer to... Figures 2a to 2bThe orientation of the surfaces is shown. It should be understood that the surfaces can be oriented in other ways if desired. The two side surfaces 3c are arranged as flat surfaces. However, the two side surfaces 3c can have different shapes and can be arranged as non-flat surfaces. If desired, the two side surfaces 3c can also be concealed or hidden in the vehicle lighting structure to prevent unwanted light emission from the lens body 1.

[0057] Lens body 1 may, for example, have the following characteristics: Figures 2a to 2b The parallelepiped structure shown has a height dimension D1, a width dimension D2, and a length dimension D3. The length dimension D3 can be varied, for example, to achieve different surface areas of the light-emitting surface 5. For instance, if a predetermined height dimension D1 is used in a specific lens body construction, and the length dimension D3 is varied for different designs of the optical lens system S, the light intensity and construction of the first light source unit 2a and the second light source unit 2b to achieve the desired characteristics can depend on the length dimension D3. However, it should be understood that, depending on the design of the vehicle or vehicle components, the system can be arranged to have other suitable shapes, such as, for example, curved or irregular shapes.

[0058] Figures 2a to 2b In the illustrated embodiment, the first optical region 6a and the second optical region 6b may appropriately have features in conjunction with the above. Figures 1a to 1b The first optical region 6a in the embodiment has the same construction. The light-affected surface 4 includes a first optical region 6a and a second optical region 6b formed by a plurality of optical elements 7, and these optical regions are configured to redirect incident light from the corresponding incident surface to the emitting surface 5. The first light source unit 2a and the second light source unit 2b can be of any type or design, and each light source unit appropriately includes components to be compatible with the light source 6b. Figures 1a to 1b In the illustrated embodiment, the first light source unit 2a contains multiple light sources 10 arranged at intervals from each other in the same manner as described. Figure 2a In the design of the optical lens system S, each light source unit includes three light sources 10, but depending on the design of the optical lens system S, each of the first light source unit 2a and the second light source unit 2b may include only one light source 10, or alternatively include two or more light sources 10.

[0059] like Figure 2bAs schematically indicated by the arrow, the light source 10 of the first light source unit 2a emits light into the first light-incident surface 3a of the lens body 1. The first optical region 6a of the lens body 1, having a plurality of optical elements 7, is arranged to redirect the incident light from the first light source unit 2a having the light source 10 from a first optical flow direction X1 to a second optical flow direction Y. In this way, the optical elements 7 in the first optical region 6a of the lens body 1 are configured to redirect the incident light from the first optical flow direction X1 to the second optical flow direction Y, wherein the second optical flow direction Y is arranged at an angle relative to the first optical flow direction X1. The lens body 1 is arranged after the first light source unit 2a along the first optical flow direction X1.

[0060] like Figure 2b As schematically indicated by the arrow, the light source 10 of the second light source unit 2b emits light into the second incident surface 3b of the lens body 1. The second optical region 6b of the lens body 1, having a plurality of optical elements 7, is arranged to redirect the incident light from the second light source unit 2b having the light source 10 from the first optical flow direction X2 to the second optical flow direction Y. In this way, the optical elements 7 in the second optical region 6b of the lens body 1 are configured to redirect the incident light from the first optical flow direction X2 to the second optical flow direction Y, wherein the second optical flow direction Y is arranged at an angle relative to the first optical flow direction X2. The lens body 1 is arranged after the second light source unit 2b along the first optical flow direction X2.

[0061] The lens body 1 is designed and constructed to achieve a uniform or substantially equal light distribution of light emitted from the light source 10 of the first light source unit 2a and the second light source unit 2b. As described above, the lens body 1 includes a first light-incident surface 3a, a second light-incident surface 3b, and a light-exit surface 5. The first light-incident surface 3a and the second light-incident surface 3b are arranged to receive incident light from the light source 10. The light-exit surface 5 is arranged to emit light received from the light source 10 through the first light-incident surface 3a and the second light-incident surface 3b. The light-exit surface 5 distributes the emitted light, for example, to the exterior of the vehicle or to the interior compartment of the vehicle. The optical lens system S may also include a protective layer, such as an outer lens covering the light-exit surface 5.

[0062] Therefore, the light emitted from the multiple light sources 10 of the first light source unit 2a is redirected from the corresponding first optical flow direction X to the second optical flow direction Y in the lens body 1, and the compact design of the optical lens system S is achieved through the redirection of the optical flow.

[0063] like Figures 2a to 2b As shown, each light source 10 is appropriately arranged at a small distance from its corresponding incident surface. Therefore, as... Figure 2bAs shown, a small gap G is provided between each light source 10 and its corresponding incident surface. In an alternative embodiment (not shown), the light source may alternatively be arranged to directly contact or be embedded within the first incident surface 3a. Instead of multiple light sources, a light guide or similar device may be used as the first light source unit 2a. Using a light guide can reduce the number of light sources used.

[0064] As described above Figures 1a to 1b The first optical region 6a and the second optical region 6b are formed by a plurality of optical elements 7, and in such a way that the extension of the first optical region 6a and the second optical region 6b is defined by the optical elements 7. The optical elements 7 are arranged as recesses I in the light-affected surface 4 of the lens body 1, and thus each optical element 7 forms a cavity in the lens body 1. When the lens body 1 is molded, the recesses I formed by the optical elements 7 in the lens body 1 can be obtained, and then the mold used is prepared with an optical element structure. Figures 2a to 2b The optical element in the illustrated embodiment has a connection with Figures 1a to 1b The embodiments shown have the same shape and structure as described, and Figure 3 and Figure 4 It is shown in more detail below.

[0065] like Figures 2a to 2b As shown, a first optical region 6a is arranged in relation to a first light source unit 2a, and in this embodiment, the lens body 1 includes a first buffer zone 11a between the first light-incident surface 3a and the first optical region 6a. The first buffer zone 11a is arranged to ensure that incident light propagates uniformly within the lens body 1 before being redirected in the first optical region 6a. The region between the first light-incident surface 3a and the first optical region 6a defines the first buffer zone 11a, and the size and shape of the first buffer zone 11a can vary depending on the design of the lens body 1. A second optical region 6b is arranged in relation to a second light source unit 2b, and in this embodiment, the lens body 1 includes a second buffer zone 11b between the second light-incident surface 3b and the second optical region 6b. The second buffer zone 11a is arranged to ensure that incident light propagates uniformly within the lens body 1 before being redirected in the second optical region 6b. The region between the second light-incident surface 3b and the second optical region 6b defines the second buffer zone 11b, and the size and shape of the second buffer zone 11b can vary depending on the design of the lens body 1.

[0066] exist Figures 2a to 2bIn the illustrated embodiment, the first optical region 6a and the second optical region 6b of the light-affected surface 4 are defined by a plurality of optical elements 7, and the plurality of optical elements 7 in the first optical region 6a and the second optical region 6b are arranged in a hexagonal pattern H. The hexagonal pattern H means that the optical elements 7 form a pattern consisting of a plurality of adjacent hexagons having six sides and six corners, and wherein, as shown... Figure 5 As schematically shown, imaginary straight lines connecting two optical elements forming a hexagon constitute the sides of the hexagon. The hexagonal pattern H is formed by paired optical elements 7, and further, by a plurality of optical elements 7 arranged in a continuously repeating hexagonal pattern. Each hexagon in the hexagonal pattern H includes a non-filled region 12, wherein the non-filled region 12 is configured to create a perspective effect within the lens body 1. The hexagonal patterns of the first optical region 6a and the second optical region 6b appropriately have [a certain characteristic / feature] in conjunction with [other elements]. Figures 1a to 1b and Figure 5 The embodiment shown has the same construction as the hexagonal pattern described.

[0067] In different embodiments of the optical lens system S, the appropriate number of light sources 10 used in each light source unit to achieve a uniform light distribution with a uniform light pattern in the lens body 1 depends on the surface area of ​​the light-emitting surface 5. The larger the surface area of ​​the light-emitting surface 5, the more light sources 10 can be used. The light sources 10 used in each light source unit can be any suitable light source for vehicle applications, such as light-emitting diodes (LEDs) with low power consumption, long lifespan, and robust construction.

[0068] The first light-incident surface 3a and / or the second light-incident surface 3b may have a flat or substantially flat structure. Each light-incident surface may be equipped with a light entrance for one or more light sources 10. In alternative embodiments not shown, the first light-incident surface 3a and the second light-incident surface 3b have a non-flat structure, such as a curved or shaped surface structure. The light-emitting surface 5 may have a flat or substantially flat structure for uniform light distribution, such as, for example... Figure 1a and Figure 2a As shown. In an alternative embodiment not shown, the light-emitting surface 5 has a non-flat structure, such as a curved or shaped surface structure. As described above, the light-affecting surface 4 is arranged to redirect incident light from inside each light-incident surface toward the light-emitting surface 5. The light-affecting surface 4 may have a flat or non-flat structure.

[0069] In different embodiments of the optical lens system S, the light-emitting surface 5 is arranged on the light-emitting plane P. O In, for example Figure 1a and Figure 2a shown. Light exit plane P OIt can be used to define the second optical flow direction Y, where the second optical flow direction Y is perpendicular to the light output plane P. O The first optical flow direction X is the direction of light entering the lens body 1 from each light source unit through each incident surface. It should be understood that light emitted from each light source unit is emitted not only in a single direction, but also in different directions within the light emission angle or viewing angle of the light source. Different light sources have different radiation patterns, and an example of a typical radiation pattern for a light-emitting diode (LED) is that most of the energy is emitted within 20 degrees of the direction of maximum light. The direction of maximum light from the light source can, for example, be used to define the first optical flow direction X. Different types of LEDs can be used for the light source 10, and suitable LEDs used in the automotive industry typically have viewing angles of 60 degrees and / or 120 degrees.

[0070] exist Figure 1b and Figure 2b In the different embodiments shown, the first optical flow direction X is arranged at an angle of approximately 90 degrees relative to the second optical flow direction Y. However, it should be understood that the lens body 1 can be arranged to redirect the incident light at an angle other than approximately 90 degrees between the first optical flow direction X and the second optical flow direction Y. The first optical flow direction X and the second optical flow direction Y can be arranged relative to each other in any desired angular relationship, and this angle can vary for different designs of the optical lens system S.

[0071] In different embodiments of the optical lens system S, the lens body 1 can be made of any suitable material, such as polymethyl methacrylate (PMMA), polycarbonate (PC), a mixture of polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS), or any other suitable plastic or other material with transparent properties. Another suitable material for forming the flexible lens body structure is silicone plastic, wherein the lens body can be molded from silicone plastic into the desired shape in a molding die. Depending on one or more materials used, the angles or angle ranges used may differ from those described, depending on the optical properties and refractive index of the materials used.

[0072] In different embodiments, the light-emitting surface 5 may, for example, include a textured structure or other surface polishing layer for more uniform light distribution. The textured structure can have any suitable texture or roughness. If the lens body 1 is made of a suitable plastic material, such as polymethyl methacrylate (PMMA), the texture of the light-emitting surface 5 can be measured, for example, according to the VDI 3400 standard. The textured structure can be obtained when molding the lens body 1, and then the mold used is prepared with a suitable textured structure.

[0073] The optical lens system S is scalable in size through the construction of the lens body 1 and the light source 10. Due to the scalability of the optical lens system S, the size of the lens body 1 can be varied, and furthermore, the number of light sources 10 used can differ between different vehicle lighting applications. The distance between the light sources 10 can be changed to alter the intensity of the light emitted from the light-emitting surface 5. The greater the distance between the light sources 10, the higher the risk of non-uniform light patterns in the light-emitting surface 5. Furthermore, if the light sources are arranged too close to each other, the optical lens system S may not be energy efficient enough. A narrow system may only require one light source 10, while a wider system may require two or more light sources 10.

[0074] The first light-incident surface 3a and / or the second light-incident surface 3b of the lens body 1 may include one or more lenses arranged to guide light emitted from one or more light sources 10 into the lens body 1. The first light-incident surface 3a and / or the second light-incident surface 3b may provide a lens for each light source, wherein these lenses are arranged in a suitable manner to guide and distribute light emitted from one or more light sources 10 into the lens body 1 to achieve a desired first optical flow direction X entering the lens body 1. The more light reflected on the optical element 7, the better the light output achieved through the light-exit surface 5. Each of the one or more light sources 10 cooperates with each of the one or more lenses, so the lens body 1 may provide a lens for each light source 10. The lenses may be arranged in different ways depending on the system design. One or more lenses may be attached to the lens body 1 as separate elements, or alternatively molded into the structure of the lens body 1.

[0075] In a non-limiting exemplary embodiment, the lens body 1 may have a width dimension D2 of at least 1 mm, and the height dimension D1 and length dimension D3 may vary depending on the specific vehicle lighting application using the system. The distance between the light sources 10 used depends on the size of the lens body 1 and the light intensity of the light sources used.

[0076] The optical lens system S can be formed as part of the vehicle lighting unit 100, such as Figures 8a to 8b The exploded diagram is shown schematically. Figure 8aIn the illustrated embodiment, the vehicle lighting unit 100 includes an optical lens system S, wherein the optical lens system S may have the configuration described above. The vehicle lighting unit 100 also includes an outer lens 101, such as a taillight or position light, which is part of, for example, an outer surface. Alternatively, the outer lens 101 faces the interior compartment of the vehicle. The outer lens 101 is suitable to be made of a clear or transparent material and may be tinted if desired. A lens body 1 is disposed inside the outer lens 101, and an outer frame structure 102 is located between the lens body 1 and the outer lens 101. The outer frame structure 102 may be configured to form a frame structure with a distance between the lens body 1 and the outer lens 101. For an attractive design of the vehicle lighting unit 100, an inner frame structure 103 may be disposed behind the lens body 1, and the inner frame structure 103 may be shaped or patterned. Different portions of the vehicle lighting unit 100 may be suitably arranged in a housing structure 104 or a similar structure for robust construction of the vehicle lighting unit 100.

[0077] Figure 8b The implementation shown is similar to Figure 8a The vehicle lighting unit 100 in this embodiment includes three optical lens systems S, each of which may have the above-described configuration. The vehicle lighting unit 100 also includes an outer lens 101, such as a taillight or position light, which is part of, for example, an outer surface. Alternatively, the outer lens 101 faces the interior compartment of the vehicle. The outer lens 101 is suitable to be made of a clear or transparent material and may be tinted if desired. A first lens body 1a, a second lens body 1b, and a third lens body 1c are arranged sequentially within the outer lens 101, with an outer frame structure 102 located between the outer lens 101 and the third lens body 1c. The lens bodies are positioned one after another with their inter-lens distances to create a continuous three-dimensional light pattern and / or an animated three-dimensional light pattern. The outer frame structure 102 may be configured to form a frame structure with a certain distance between the third lens body 1c and the outer lens 101. An inner frame structure 103 may be arranged behind the first lens body 1a for an attractive design of the vehicle lighting unit 100, and the inner frame structure 103 may be shaped or patterned. Different parts of the vehicle lighting unit 100 can be suitably arranged in the housing structure 104 or a similar structure for the robust construction of the vehicle lighting unit 100. Through the perspective effect of the lens bodies and by continuously activating different light sources of the combined optical lens system S, it is possible to arrange three lens bodies one after another to create a continuous three-dimensional light pattern and / or an animated three-dimensional light pattern. It should be understood that any suitable number of optical lens systems S with lens bodies can be used to create a continuous and / or animated three-dimensional light pattern, such as two lens bodies, three lens bodies, or four or more lens bodies arranged successively.
