[0065] Compared with the prior art, the present invention has the following beneficial effects:

[0066] 1. The present invention adopts an electric design to use a unified opening and replace different optical function modules at the same opening position. Specifically, the multiple optical function modules are driven by a driving component to achieve switching of the optical function modules at the light incident surface of the lens module. Multiple optical function modules share one lens module, and multiple optical functions are achieved through a simple structure, saving design space and cost.

[0067] 2. The present invention realizes a multifunctional design and ensures a consistent shape by adopting the same universal module lens. Specifically, the light-emitting surfaces of different optical function modules are adjusted so that different optical function modules can share one module lens. As for the focal length, the focal lengths from the focal points of the rear end light-emitting surfaces of the high beam module and the low beam module to the lens module are made consistent, so that one lens module can be shared. The focal lengths of the rear end light-emitting surfaces of the high beam module and the low beam module are designed separately according to their functions. The design of the signal light module is not greatly affected by the focal length and can be adjusted by adjusting the diffusion of the rear end optical surface. As for widening, both the high beam module and the low beam module have requirements for widening design. Therefore, without changing the focal lengths from the focal points of the high beam module and the low beam module to the lens module, the rear end light-emitting surfaces of the high beam module and the low beam module are tilted to equivalently shift the focus to achieve a widened light pattern design.

[0068] 3. The present invention adopts a split design to split the lens module and the optical function module, thereby reducing the size of the parts and ensuring the optical quality of the parts. Different optical function modules share one lens, reducing the development of molds.

[0069] 4. The present invention changes the focal position by adjusting the light-emitting surface of the rear-end optical function module, thereby realizing optical characteristics of different functions and ensuring the consistency of the universal module lens. BRIEF DESCRIPTION OF THE DRAWINGS

[0125] This embodiment integrates the high and low beams and signal lights of the vehicle lights under the same lens module, realizing an optical solution with different functions in the same opening. The focal position of the universal module is designed by taking into account the different characteristics of the high and low beams, and the focal length of the high beam is designed to be greater than that of the low beam, and the high beam focus does not need to be placed near the boundary of the total reflection bowl like the low beam focus. That is, the high beam module is designed based on the low beam module first, and the signal light is not affected. Under this condition, the universal module lens can be fully applicable to the high and low beam and signal light functions. Because each function requires a different module combination to achieve the optical effects of the high beam, low beam and signal light, the focus is diversified.

[0127] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.

[0128] This embodiment provides a universal modular design of a small-aperture headlight optical system, wherein the low beam module includes a low beam light source 101 , a low beam main light type total reflection bowl 102 , a low beam auxiliary light type total reflection bowl 103 , a low beam light input lens 104 , and a low beam light output lens 105 .

[0129] The low-beam main-light type total reflection bowl 102 comprises a first cut-off region 1021 , a second cut-off region 1022 , a third cut-off region 1023 , and a cut-off inflection point 1024 .

[0130] The low beam auxiliary light type total reflection bowl 103 includes a first three-zone area 1031 , a second three-zone area 1032 , and a third three-zone area 1033 .

[0131] The cutoff lines A, B, and C of the low beam light type are formed by the first cutoff line area 1021, the second cutoff line area 1022, and the third cutoff line area 1023 of the low beam main light type total reflection module 102, and a D corresponding to the cutoff line inflection point 1024 is formed. The cutoff line position is adjusted by adjusting the boundary position.

[0132] The regions E, F and G of the three-zone light pattern are formed by the first three-zone region 1031 , the second three-zone region 1032 and the third three-zone region 1033 of the boundary of the low-beam auxiliary light pattern total reflection bowl 103 .

[0133] The low beam auxiliary light type total reflection bowl area increases the distance between the low beam light source module 101 and the low beam main light type total reflection bowl 102, reduces the thermal risk of parts, and increases the focal length limit of the total reflection bowl.

[0134] The high beam module includes a high beam light source 201 , a high beam main light type total reflection bowl 202 , a high beam light input lens 204 , and a high beam light output lens 205 .

[0135] The signal light module includes a signal light source 301, a signal light main light type full reflection bowl 302, a signal light incident lens 303, and a signal light exit lens 304. The signal light main light type full reflection bowl 302 may be designed with a diffusion pattern, or the signal light exit lens module 304 may be used to diffuse the light.

[0136] The universal module lens includes a universal module lens light entrance surface 401 and a universal module lens light exit surface 402. Since the focal length of the high beam is designed to be greater than that of the low beam, and the high beam focus does not need to be placed near the boundary of the total reflection bowl like the low beam focus, the lens focal length of the universal module is based on the low beam module design before the high beam module design, and the signal light is not affected. The universal module lens needs to be fully applicable to the high and low beam and signal light functions, and each function requires a different module combination to achieve the high beam, low beam and signal light optical effects, resulting in a diversity of focus. Therefore, under the premise of ensuring that the universal module lens remains unchanged, the lens light exit surfaces of the high and low beam modules and the signal light module are adjusted to achieve the design requirements. The number and arrangement of modules are designed according to the different performance and styling requirements of each function, and finally modular replacement of different functions under the same styling can be achieved. Different functions can also be achieved under the same opening through an electric structure.

[0137] Furthermore, the focal points of the universal module lens light incident surface 401 and the module lens light exit surface 402 are adjustable left and right, up and down, front and back in space, and are not just on the central optical axis.

[0138] Furthermore, the surface shapes of the low beam output lens 105 and the high beam output lens 205 can be adjusted. The angled plane can shift the focus of the universal module lens to the left or right or up or down; the convex surface shape can reduce the focal length of the universal module lens; conversely, the concave surface shape can increase the focal length of the universal module lens; they can also be combined into free-form surfaces to achieve design requirements.

[0139] Furthermore, microstructures may be added to the surfaces of the low-beam light output lens 105 and the high-beam light output lens 205 to improve the uniformity of the road surface.

[0140] Furthermore, the focal lengths of the low beam main light type total reflection bowl 102, the high beam main light type total reflection bowl 202 and the signal light main light type total reflection bowl 302 can be adjusted according to design requirements (1mm to 5mm). The smaller the focal length, the more concentrated the light pattern and the larger the maximum value. Conversely, the more dispersed the light pattern and the smaller the maximum value.

[0141] Furthermore, the outer surfaces of the low beam main light type total reflection bowl 102 , the high beam main light type total reflection bowl 202 and the signal light main light type total reflection bowl 302 may be plated with aluminum, thereby reducing light loss and improving optical efficiency.

[0142] Furthermore, the position and shape of the cut-off line area of ​​the low-beam main-beam type total reflection bowl 102 are adjustable and can be designed according to different regulations and customer requirements.

[0143] Furthermore, the surface of the low beam auxiliary light type total reflection bowl 103 can be designed according to requirements, and can be a flat surface, a free-form surface, etc.

[0144] Furthermore, the three-zone design on the low beam auxiliary light type full reflection bowl 103 area can be an overall segmented pattern, or can be other three-zone designs such as a separate design for a special area.

[0145] Furthermore, the outer surface of the low beam auxiliary light type total reflection bowl 103 may be aluminum-plated, thereby reducing light loss and improving optical efficiency.

[0146] Furthermore, the outer surface of the low beam auxiliary light type total reflection bowl 103 can be provided with skin texture, thereby reducing the three-zone stray light.

[0147] Furthermore, the surface shapes of the low beam incident lens 104, the high beam incident lens 204 and the signal light incident lens 303 can be adjusted according to design requirements, and can converge light or diverge light, and the extent of convergence or diffusion can also be adjusted by the surface shape.

[0148] Furthermore, multiple low beam, high beam and signal light optical systems are finally combined into low beam, high beam and signal lights, and their number, arrangement and lighting can be adjusted according to performance requirements, styling requirements and lighting requirements.

[0149] Furthermore, the low beam light source module 101, the high beam light source module 201 and the signal light source module 301 can be single chip, multi-chip or SMD LED or laser light source or RGB light source. The signal light source module 301 can also be RGB LED.

[0150] Further, the low beam light source module 101 is configured as a SMD LED, which is integrated on a PCBA or integrated on a heat sink. When integrated on a heat sink, the PCBA board is connected via a metal wire. In other embodiments, other light source types can be selected according to actual needs.

[0151] Further, the high beam light source module 201 is configured as a SMD LED, which is integrated on a PCBA or integrated on a heat sink.

[0154] Embodiment 3:

[0155] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.

[0156] More specifically, Figure 2 As shown in the principle diagram of light being refracted twice by parallel media, after being refracted twice by parallel medium surfaces, the light will be delayed in converging (or the focal length will be increased). For example, light S1O1 is emitted from the medium, reaches the interface with the air and is refracted into light O1O2, and then continues to move forward and reaches the interface with the medium again for a second refraction. After refraction, the light finally converges at point S2. If light O1O2 is no longer refracted twice, it will converge at S2'. The distance between the high and low beam and signal light modules of this embodiment and the universal module lens is almost zero, so the influence of focal length can be ignored in theory. Figure 3 Schematic diagram of the double refraction of light in the vertical direction in the modular system Figure 4 The schematic diagram of the two horizontal refractions of light in the modular system is shown in the figure. The two refraction states are not reflected in the design, only the focal length change is reflected.

[0157] More specifically, Figure 5As shown in the schematic diagram of each modular optical system, after the focal length of the low beam system is clear (60mm), the size and optical surface of the universal module lens can be determined. Therefore, the principle is as follows: the light is emitted from the low beam light source 101, and then converged by the low beam incident lens 104 and enters the part. A part reaches the low beam main light type total reflection bowl 102 and is totally reflected into A1A2 light, and after two refractions through the low beam light output lens 105 and the universal module lens 6, it reaches the light output surface of the universal module lens, and is emitted as A2A3 light, and forms the low beam main light type after reaching the 25-meter screen.

[0158] like Figure 7 The optical principle diagram of the modular low beam optical system. The cutoff lines A, B, and C of the low beam light type are formed by the first cutoff line area 1021, the second cutoff line area 1022, and the third cutoff line area 1023 of the boundary of the low beam main light type total reflection module 102, and a D corresponding to the cutoff line inflection point 1024 is formed. The cutoff line position is adjusted by adjusting the boundary position. The other part reaches the low beam auxiliary light type total reflection bowl 3 for total reflection into B1B2 light, and reaches the light exit surface of the universal module lens after two refractions of the light exit lens module 105 and the universal module lens 6, and is emitted as B2B3 light. After reaching the 25-meter screen, a three-zone light type is formed. The areas E, F, and G of the three-zone light type are formed by the first three-zone area 1031, the second three-zone area 1032, and the third three-zone area 1033 of the boundary of the low beam auxiliary light type total reflection bowl 103. The low beam auxiliary light type full reflection bowl area increases the distance between the low beam light source 1 and the low beam main light type full reflection bowl 2, reduces the thermal risk of parts, and increases the focal length limit of the full reflection bowl. After the focus of the universal module lens is clear, based on this condition, the high beam system (rear focal length 30mm) can be designed. The optical path is as follows Figure 5 As shown in the figure, the signal light is not affected by the focal length, but only by the pattern diffusion angle, so the size of the signal light module can be designed at will. Considering the relationship between uniformity and depth, the longer the size, the better, while taking into account efficiency. The light path is shown in the figure. The light enters the signal light module, and after total reflection, G1G2 reaches the pattern of the light-emitting surface 304 of the signal light, and diffuses into G2G 31 and G2G 32 After multiple total reflections in the universal module lens, it is finally emitted on the 5-meter plane G n1 and G n2 .

[0159] More specifically, the universal module lens needs to be fully applicable to the functions of high and low beams and signal lights, and each function requires a different module combination to achieve the optical effects of high beams, low beams and signal lights, resulting in the diversity of focus. Therefore, under the premise of ensuring that the universal module lens remains unchanged, the lens light exit surfaces of the high and low beam modules and signal light modules are adjusted to meet the design requirements. Figure 6As shown in the schematic diagram of the influence of different surface shapes on the focal position of the modular lens, the angled plane can shift the focal point of the universal module lens to the left or right or up and down; the convex surface shape can reduce the focal length of the universal module lens; conversely, the concave surface shape can increase the focal length of the universal module lens; they can also be combined into free-form surfaces to achieve design requirements.

[0160] More specifically, Figure 8 and Fig. 9 As shown in the figure, because the low beam spot has a higher requirement for brightness, the low beam spot has a larger focal length and a more concentrated light pattern on the basis of being centered. On the contrary, if the low beam is widened, the focal length is smaller and the light pattern is more scattered. Figure 8 As shown in the schematic diagram of the modular low-beam optical system combination and the schematic diagram of the low-beam light patterns of 9 different modules, the left and right positions of the focus after deflection by the light-emitting lens module 5.1 also affect the optical design. When the focus is at the center position (module 1.1), the light pattern is centered (light pattern 1.1), which is used for the low-beam bright spot design; when the focus deviates from the center position (module 2.1), the light pattern will also deviate from the center (light pattern 2.1), which is used for the low-beam widening design. Similarly, after the focus is offset to different positions of the center, the corresponding light pattern 3.1, light pattern 4.1, and light pattern 5.1 are formed. Finally, all light patterns are combined to form the low-beam light pattern, and then the number of different modules required is confirmed according to the performance requirements, and they are arranged according to the styling requirements.

[0161] More specifically, Fig.10 As shown, similarly, the principle of the high beam system is the same as that of the low beam system, with a larger focal length and a more concentrated light pattern. On the contrary, if the low beam is widened, the focal length is smaller and the light pattern is more scattered. The left and right positions of the focus of the light-emitting lens module 5.2 also affect the optical design. When the focus is at the center position (module 1.2 and module 3.2), the light pattern is centered (light pattern 1.2 and light pattern 3.2), which is used as a high beam bright spot design; when the focus deviates from the center position (module 2.2 and module 4.2), the light pattern will also deviate from the center (light pattern 2.2 and light pattern 4.2), which is used as a high beam widening design. Similarly, after the focus is offset to different positions of the center, the corresponding light pattern is formed. Finally, all light patterns are combined to form the high beam light pattern, and then the number of different modules required is confirmed according to the performance requirements, and they are arranged according to the modeling requirements.

[0162] More specifically, Fig.11 , under the same universal module lens opening, different functions can be realized through the electric structure, and the rear end can be moved or rotated. Or the overall function of multiple modules can be replaced, and under the same opening, the high and low beam and signal light functions can be replaced by mechanical methods such as up and down. In the figure, a is horizontal movement, c is vertical movement, and b is rotation.

[0163] Figure 3 and Figure 4A in the figure is a light output lens module of a low beam module, a high beam module or a signal light module.

[0164] The present invention realizes a multifunctional design and ensures a consistent shape by adopting the same universal module lens.

[0165] The light source of the present invention is configured as a SMD LED, which is integrated on a PCBA or a heat sink and connected to a PCB board via a metal wire. In other embodiments, other light source types can be selected according to actual needs.

[0167] The present invention can also be freely combined with each other according to various design requirements to finally realize a through-light.
