The light-emitting directions of the low beam output lens module 105, the high beam output lens module 204 and the signal light output lens module 304 are consistent.
[0101] At least one of the low beam module body 1, the high beam module body 2, and the traffic light module body 3 can be configured as multiple units, enabling any of the following arrangement structures: horizontal array arrangement, vertical array arrangement, and tree arrangement. The low beam module body 1 and the high beam module body 2 are staggered vertically and share the same circuit board 4 and heat sink.
[0102] like Figure 1 As shown, arrangement 1 is a horizontal array, arrangement 2 is a vertical array, and arrangement 3 is a tree-like arrangement. Other shapes can also be arranged according to actual needs. In this embodiment, each individual module performs the functions of high and low beams and traffic lights. Each individual module can be made similar in appearance and then arranged according to customization.
[0103] A cutoff line region is formed between the primary low beam total internal reflection module 102 and the secondary low beam total internal reflection module 103.

The primary low beam total internal reflection module 102 and the secondary low beam total internal reflection module 103 are connected through the matte textured surface 1025, which is used to diffuse light that would otherwise cause stray light in the three zones outside the module. The cutoff line structure is set on the matte textured surface 1025. The primary low beam total internal reflection module 102 and the matte textured surface 1025 are located above the low beam incident lens module 104, and the light entering direction of the low beam source module 101 is upward.

If the traffic light source module uses RGB LEDs, a colored lighting effect can be achieved.
[0108] The traffic lights use a thick-walled component system with very small openings, similar in appearance to the high and low beams, which is conducive to a unified design. The light emitted by the traffic light module will form a diffused light spot pattern on a 5m screen, with high brightness at the center and gradually weakening towards the edges.

[0110] The boundary of the low beam assist light pattern total internal reflection module 103 includes: a first three-zone region 1031, a second three-zone region 1032, and a third three-zone region 1033 connected in sequence; the first three-zone region 1031 is set to correspond to the first cutoff line region 1021, the second three-zone region 1032 is set to correspond to the cutoff line 1022, and the third three-zone region 1033 is set to correspond to the second cutoff line region 1023.

The high beam output lens module 204 has two focal points: one located at the position forming the high beam pattern, and the other located between the primary high beam pattern total internal reflection module 202 and the high beam output lens module 204.

Each small module is part of the low beam, high beam, or signal light pattern, and multiple modules are arranged and combined to form low beam, high beam, and signal light functions. Furthermore, software control allows for a wider range of lighting effects. The minimalist optical system design integrates the light-incident surface, total internal reflection surface, and light-exit surface of the low beam, high beam, or signal light onto a single thick-walled component, coupled with a light source module to achieve high / low beam and signal light functions. After simplification, the module size is significantly smaller than traditional modules, without sacrificing optical efficiency. Additionally, each module can be made to the same size, with the number and arrangement of modules tailored to different performance and aesthetic requirements. Due to the system characteristics of high / low beams, they can be staggered vertically, sharing a single circuit board and heat sink. Signal lights, being unrestricted, can be placed arbitrarily, thus reducing design costs and space requirements.

[0135] The regions E, F, and G of the three-zone light pattern are formed by the boundaries of the near beam auxiliary light pattern total internal reflection module 103: the first three-zone region 1031, the second three-zone region 1032, and the third three-zone region 1033.
[0136] The area of the low beam auxiliary light type total internal reflection module increases the distance between the low beam source module 101 and the low beam main light type total internal reflection module 102, reduces the thermal risk of the parts, and improves the focal length limit of the total internal reflection module.
[0137] Figure 13 middle, Figure 13 .1 is a top view of the small-aperture low beam module. Figure 13 .2 is Figure 13 .1 Schematic cross-sectional view along line AA.
[0138] like Figure 14 As shown, a portion of the light reaches the near beam main light type total internal reflection module 102 for total internal reflection into A1A2 light rays, and is emitted as A2A3 light rays through the near beam output lens module 105. After reaching the 25-meter screen, it forms the near beam main light type. The other portion reaches the near beam auxiliary light type total internal reflection module 103 for total internal reflection into B1B2 light rays, and is emitted as B2B3 light rays through the near beam output lens module 105. After reaching the 25-meter screen, it forms the three-zone light type.
[0139] The near beam exiting lens module 105 features two focal points: one (F') at 25 meters (as required by regulations), and the other (F1) at the upper boundary of the near beam auxiliary total internal reflection module 103, with their front-to-back positions within ±5mm. The left-to-right positions are unrestricted and can be designed according to the target beam pattern (near beam bright spot pattern, near beam broadened pattern). To reduce light loss and improve optical efficiency, the outer surface of the near beam main total internal reflection module 102 is aluminum-plated. The near beam entrance lens module improves light input efficiency. Simultaneously, the minimalist optical system within this opening reduces the module size, with a maximum length of 55mm and a minimum length of only 40mm, significantly smaller than conventional optical system designs, thus also improving light output efficiency. The integrated design reduces light loss caused by multiple parts. Therefore, when the aperture is 15mm x 15mm, the efficiency of this high beam system can reach 53%; when the aperture is 10mm x 10mm, the efficiency of this high beam system can reach 40%; and even with an aperture of 5mm x 5mm, the efficiency of this low beam system can still reach 25%, which is much higher than the efficiency of other modules with extremely small apertures (10%).
[0140] Figure 14 Figure 1 shows a schematic diagram of light propagation in a small-aperture low beam module. Because the brightest point of the low beam is near the cutoff line, the cutoff line should be placed directly above the light emission from the low beam source module, i.e., within ±5 degrees of the emission angle. Therefore, the surface below the cutoff line of the low beam main beam total internal reflection module will cause stray light, affecting optical performance and regulatory requirements. Furthermore, being too close to the low beam source module can also pose a risk to the heat resistance of components. Figure 14 The light rays shown in Figure 2 illustrate the light propagation in a low beam module without an matte finish. In a traditional design, light emitted from the low beam source module passes through the low beam incident lens module and enters the thick-walled component. A portion of the light, A12, reaches the low beam main beam type total internal reflection module, while another portion, B12, reaches the sidewall below the cutoff line. Because the divergence angle near the center of the light-emitting module is relatively strong, no matter how it is designed or an absorption coating is added, it cannot be completely eliminated, thus easily generating stray light that affects regulations. Therefore, this embodiment designs a special three-zone structure, such as... Figure 14The diagram in section .3 illustrates the light propagation in a low beam module with a matte textured surface. Light rays B13 and C13, originally below the cutoff line, continue to propagate within the structure. Ray B13 assists the total internal reflection module design in positioning the light within zone B23, while unwanted light rays are diffused out onto the matte surface B'13. Ray C13, being close to the center of the low beam light source module's divergence angle, diffuses directly out through the matte surface C23. This ensures the position of the main beam cutoff line, increases the distance between the low beam light source module 101 and the main low beam total internal reflection module 102, reduces the thermal risk of components, improves the focal length limit of the main low beam total internal reflection module, and avoids the influence of stray light.
[0141] like Figure 15 The diagram illustrates the optical principle of a simplified small-aperture near beam module system, showing the bright spot and beam widening design. The focal position of the near beam output lens module 105 also affects the optical design. When the focal point F1 is centered (module 1.1), the beam pattern is centered (beam pattern 1.1), suitable for near beam bright spot design. When the focal point F2 deviates from the center (module 2.1), the beam pattern also deviates from the center (beam pattern 2.2), suitable for near beam widening design. Similarly, because the near beam bright spot requires high brightness, a larger focal length (module 1.1) results in a more focused beam pattern (beam pattern 1.1) while maintaining a centered position. Conversely, a smaller focal length (module 2.1) results in a more diffused beam pattern (beam pattern 2.1) for near beam widening design.
[0142] Figure 15 middle, Figure 15 .1 represents two low beam module systems: one with the focus at the center position and the other with the focus off-center. Figure 15 .2 is Figure 15 A schematic diagram of the beam pattern formed by the two low beam module systems in .1.
[0143] like Figure 16 As shown, the low beam in this embodiment is as follows: Figure 16 A schematic diagram illustrating the brightness spot and optical performance of a minimalist small-aperture near-beam module system is shown. Figure 16 .1 and Figure 16 .4 shows the energy distribution map and uniformity grayscale map of the near-light bright spot. Figure 16 .2 and 16.5 are the energy distribution map and uniformity grayscale map of near-light broadening 1. Figure 16Figures .3 and 16.6 show the energy distribution and uniformity grayscale of the near beam broadening 2. In this embodiment, the focal position of the near beam output lens module 105 is horizontally adjusted. When the focal point is in the center, the beam pattern center is at 0 degrees. When adjusted 3mm to the right, the center of the broadened beam pattern shifts 10 degrees to the left, and the left boundary of the beam pattern reaches -25 degrees, which is near beam broadening 1. When the focal point shifts 5mm to the right, the center of the broadened beam pattern shifts 20 degrees to the left, and the left boundary of the beam pattern reaches -35 degrees, which is near beam broadening 2. The right beam pattern uses the same design method, thus meeting the basic angle requirements for near beam broadening. Multiple modules can be combined to form a near beam pattern, offering great flexibility and enabling the fulfillment of different customer styling and lighting requirements.
[0144] The high beam module includes a high beam light source module 201, a high beam main beam type total internal reflection module 202, a high beam entrance lens module 204, and a high beam exit lens module 205.
[0145] Figure 17 middle, Figure 17 .1 is a top view of the high beam module. Figure 17 .2 is Figure 17 .1 Schematic diagram of cross section along line AA.
[0146] like Figure 19 As shown, Figure 19 The optical schematic diagram of the minimalist small-aperture high beam module system shows the bright spot and widening design. The left and right positions of the focal point of the high beam output lens module 204 also affect the optical design. When the focal point F1 is in the center position (module 1), the light pattern is centered (light pattern 1), which is used for the high beam bright spot design. When the focal point F2 is off-center (module 2), the light pattern will also be off-center (light pattern 2), which is used for the high beam widening design.
[0147] Figure 19 middle, Figure 19 .1 is a schematic diagram of two high-beam module systems: one with the focus at the center and the other with the focus off-center. Figure 19 .2 is Figure 19 .1 is a schematic diagram of the beam pattern formed by a high-beam module system with the focus at the center. Figure 19 .3 is Figure 19 .1 Schematic diagram of the light pattern formed by the high beam module system with the focus off-center.
[0148] like Figure 20 As shown, the high beam of this design is as follows: Figure 20 A schematic diagram illustrating the brightness and optical performance of a minimalist small-aperture high-beam module system is shown. Figure 20 .1 and Figure 20 .4 shows the energy distribution map and uniformity grayscale map of the bright spot in the high beam. Figure 20.2 and 20.5 are the energy distribution map and uniformity grayscale map of the high beam broadening by 1. Figure 20 Figures 0.3 and 20.6 show the energy distribution and uniformity grayscale of the high beam broadening 2. This design involves horizontally adjusting the focal position of the high beam output lens module 204. When the focal point is at the center, the beam pattern center is at 0 degrees. When adjusted 3mm to the right, the center of the broadened beam pattern shifts 3 degrees to the left, and the left boundary of the beam pattern reaches -14 degrees, which is high beam broadening 1. When the focal point shifts 5mm to the right, the center of the broadened beam pattern shifts 6 degrees to the left, and the left boundary of the beam pattern reaches -17 degrees, which is high beam broadening 2. The same design method is used for the right-side beam pattern, thus meeting the basic angular requirements for high beam broadening.
[0149] like Figure 21 A simplified diagram illustrating the high-beam optical performance of a 15mm x 15mm aperture. Figure 21 .1 and Figure 21 .2 shows the energy distribution map and uniformity grayscale map of the high beam pattern.
[0150] The traffic light module includes a traffic light light source module 301, a traffic light main light type total internal reflection module 302, a traffic light incident lens module 303, and a traffic light exiting lens module 304.
[0151] The main beam total internal reflection module 302 of the traffic light can be designed with a diffusion pattern, or the light can be diffused through the light-emitting lens module 304 of the traffic light. Each module can be made to the same size, and the number and arrangement of modules can be designed according to different performance and shape requirements.
[0152] Furthermore, the focal lengths of the low beam main beam total reflection module 102, the high beam main beam total reflection module 202, and the traffic light main beam total reflection module 302 can be adjusted according to design requirements (1mm to 5mm). The smaller the focal length, the more focused the light pattern and the larger the maximum value; conversely, the more focused the light pattern and the smaller the maximum value.
[0153] Furthermore, the outer surfaces of the low beam main beam total reflection module 102, the high beam main beam total reflection module 202, and the traffic light main beam total reflection module 302 can be plated with aluminum, thereby reducing light loss and improving optical efficiency.
[0154] Furthermore, the position and shape of the cutoff line area of the low beam main beam type total internal reflection module 2 are adjustable and can be designed according to different regulations and customer requirements.

[0157] Furthermore, the outer surface of the low beam assist type total internal reflection module 3 can be plated with aluminum, thereby reducing light loss and improving optical efficiency.
[0158] Furthermore, the outer surface of the low beam assist type total internal reflection module 3 can be textured to reduce stray light in the three zones.
[0159] Furthermore, the surface shape of the low beam entrance lens module 104, the high beam entrance lens module 204, and the signal light entrance lens module 303 can be adjusted according to design requirements. They can converge or diverge light, and the size of their convergence or divergence can also be adjusted by the surface shape.
[0160] Furthermore, for the near beam output lens module 105 and the far beam output lens module 205, the smaller the focal length, the higher the efficiency, the more diffused the light pattern, and the smaller the maximum value; conversely, the larger the focal length, the lower the efficiency, the more focused the light pattern, and the larger the maximum value.
[0161] Furthermore, the surfaces of the low beam output lens module 105 and the high beam output lens module 205 can be augmented with microstructures to improve road surface uniformity.
[0162] Furthermore, multiple low beam, high beam, and signal light optical systems are ultimately combined into low beam, high beam, and signal lights. Their number, arrangement, and illumination can be adjusted according to performance requirements, design requirements, and illumination requirements.
[0163] Furthermore, the low beam light source module 101, the high beam light source module 201, and the signal light light source module 301 can be single-chip, multi-chip, or surface-mount LED, laser, or RGB light source. The signal light light source module 301 can also be an RGB LED.
[0164] Furthermore, the low beam light source module 101 is configured as a surface-mount LED, which is integrated onto the PCBA or onto a heat sink. When integrated onto a heat sink, it is connected to the PCBA board via metal wires. In other embodiments, other light source types can be selected according to actual needs.
[0165] Furthermore, the high-beam light source module 201 is configured as a surface-mount LED, which is integrated onto the PCBA or onto a heat sink.

[0167] Furthermore, the material of this system can be polycarbonate (i.e., PC), polymethyl methacrylate (i.e., PMMA), glass, or silicone.
[0168] Example 3:
[0169] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.
[0170] More specifically, in this embodiment, the opening is 5mm x 5mm, such as... Figure 2 Modular view of a single low beam module and Figure 6 The optical principle diagram of the near beam modular optical system is shown in the figure. The near beam module includes a near beam source module 101, a near beam main beam total internal reflection module 102, a near beam auxiliary beam total internal reflection module 103, a near beam entrance lens module 104, and a near beam exit lens module 105.
[0171] Figure 6 middle, Figure 6 .1 is a schematic diagram highlighting the three regions of the low beam assist total internal reflection module. Figure 6 .2 is a schematic diagram highlighting the three-zone light pattern and the cutoff line light pattern formed by the three-zone region and the cutoff line region. Figure 6 .3 is a schematic diagram showing the overall surface segmentation and patterning of the low beam auxiliary light type total internal reflection module. Figure 6 .4 is a schematic diagram of the partial aluminum plating on the outer surface of the low beam auxiliary light type total internal reflection module.
[0172] The low beam main beam total internal reflection module 102 includes a first cutoff region 1021, a second cutoff region 1022, a third cutoff region 1023, and a cutoff inflection point 1024. The low beam auxiliary beam total internal reflection module 103 includes a first three-zone region 1031, a second three-zone region 1032, and a third three-zone region 1033. The cutoff lines A, B, and C of the low beam pattern are formed by the boundaries of the first cutoff region 1021, the second cutoff region 1022, and the third cutoff region 1023 of the low beam main beam total internal reflection module 102, and form a point D corresponding to the cutoff inflection point 1024. The cutoff line position is adjusted by adjusting the boundary position. The three-zone regions E, F, and G of the three-zone pattern are formed by the boundaries of the first three-zone region 1031, the second three-zone region 1032, and the third three-zone region 1033 of the low beam auxiliary beam total internal reflection module 103.
[0173] The area of the low beam auxiliary light type total internal reflection module increases the distance between the low beam source module 101 and the low beam main light type total internal reflection module 102, reduces the thermal risk of the parts, and improves the focal length limit of the total internal reflection module.
[0174] More specifically, such as Figure 7 Schematic diagram of near-beam modular optical system assembly and Figure 8 As shown in the schematic diagram of the light patterns of different modules in the low beam, the left and right positions of the focal point of the light-emitting lens module 105 also affect the optical design. When the focal point is in the center position (module 1.1), the light pattern is centered (light pattern 2.1) and is used for the design of the bright spot in the low beam; when the focal point deviates from the center position (module 1.1), the light pattern will also deviate from the center (light pattern 2.1) and is used for the design of the widening of the low beam.
[0175] Similarly, as Figure 5 The diagram illustrates the effect of different lens focal lengths on the near and far beam module system. Because the near beam spot requires higher brightness, a larger focal length (module 1.1) is used to center the near beam spot, resulting in a more focused beam pattern (beam pattern 1.1). Conversely, a smaller focal length (module 2.1) is used for a wider near beam design, resulting in a more diffuse beam pattern (beam pattern 2.1).
[0176] Figure 5 middle, Figure 5 .1 represents two low-light modules with different lens focal lengths. Figure 5 .2 is Figure 5 A schematic diagram of the beam pattern formed by the two low beam modules in Figure 1. Figure 5 .3 represents two high-beam modules with different lens focal lengths. Figure 5 0.4 is Figure 5 A schematic diagram of the light pattern formed by the two high beam modules in section 3.
[0177] Following this pattern, as the focus shifts to different positions from the center, modules 3.1, 4.1, and 5.1 form corresponding beam patterns 3.1, 4.1, and 5.1. Finally, all beam patterns are combined to form the near beam pattern. Then, based on performance requirements, the required number of different modules is determined, and they are arranged according to the design requirements.
[0178] Figure 9 middle, Figure 9 .1 represents four high-beam modules with their focus at the center position and their focus off-center. Figure 9 .2 is Figure 9 A schematic diagram of the beam pattern formed by the four high-beam modules in Figure 1. Figure 9 .3 is Figure 9 The light pattern formed by the four light patterns in .2 together.
[0179] More specifically, similarly, the design principles of the high-beam module optical system are as follows: Figure 9As shown in the schematic diagram of the modular high-beam optical system, the left and right position of the focal point of the light-emitting lens module 205 also affects the optical design. When the focal point is in the center position (modules 1.2 and 3.2), the light pattern is centered (light pattern 1.2 and light pattern 3.2), used for the high-beam bright spot design; when the focal point is off-center (modules 2.2 and 4.2), the light pattern will also be off-center (light pattern 2.2 and light pattern 4.2), used for the high-beam widening design. Similarly, as... Figure 5 The diagram illustrates the effect of different lens focal lengths on the high and low beam module system. Because the high beam spot requires higher brightness, a larger focal length (module 1.2) is used to center the high beam spot, resulting in a more focused beam pattern (beam pattern 1.2). Conversely, a smaller focal length (module 2.2) is used for a wider high beam design, resulting in a more diffused beam pattern (beam pattern 2.2). This pattern continues, with different focal lengths shifting from the center to different positions, creating corresponding beam patterns. Finally, all beam patterns are combined to form the high beam pattern. Based on performance requirements, the required number of different modules is determined and arranged according to the design specifications.
[0180] More specifically, such as Figure 10 As shown in the schematic diagram of the high and low beam module combination, due to the system characteristics of high and low beams, the high and low beams can be placed vertically and staggered, sharing a single circuit board and heat sink. Since there are no restrictions, the traffic lights can be placed arbitrarily, thus reducing design costs and space requirements.
[0181] More specifically, such as Figure 11 The schematic diagram shows a modular combination of high and low beams and traffic lights. Each module can be made to the same size, and the number and arrangement of modules can be designed according to different performance and aesthetic requirements. Because the modules have an opening of 5mm x 5mm, they can be freely arranged into various special shapes, such as horizontal, vertical, or tree-like arrangements, etc. Figure 1 The schematic diagram of the modular design of the high beam / low beam and traffic light modules is shown in Figure A.
[0182] 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. It can also be a single-chip, multi-chip, or laser light source.
[0183] This embodiment can be configured to generate multiple light distributions, each of which has a different type. The type of each light distribution is any one 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.
[0184] This utility model adopts a modular design, in which each module can be made to the same size. The number of modules can be designed according to different performance requirements, and they can be arranged horizontally, vertically, or in a tree shape.
[0185] This invention can be configured to generate multiple light distributions, each of which is of a different type. The type of each light distribution is any one 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 light, turn signal light, daytime running light, welcome light, ambient light, etc.
[0186] This utility model can also be combined in various ways to achieve a through-light effect according to various design requirements.
