Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a multi-functional switching automotive lighting system, and more particularly to a universal modular system for a small-aperture automotive lighting system. Background Technology

[0002] With the development of intelligent vehicles, the requirements for headlights in terms of styling and intelligence are becoming increasingly stringent. Currently, styling design remains largely focused on aesthetics, ranging from sporty and conservative to exaggerated designs. Intelligence features are limited to simple animation effects and projection displays. Mechanized motion structures have not yet been widely adopted, and the market only offers simple variations of individual functions. Multifunctional intelligent headlights have not been realized due to the complexity and cost of optical systems; each function requires a separate optical system, increasing design space and cost, and also increasing the degree of assistance required from the motion mechanism. Therefore, the urgent issue to be addressed is how to achieve a more intelligent headlight solution.

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

[0066] 1. This utility model, through its electric design, enables the replacement of different optical functional modules using a unified opening at the same opening position. Specifically, multiple optical functional modules are driven by a drive component to switch the optical functional modules at the light-incident surface of the lens module. Multiple optical functional modules share a single lens module, achieving multiple optical functions through a simple structure, saving design space and cost.

[0067] 2. This utility model achieves a multi-functional design and ensures a consistent shape by using the same universal modular lens. Specifically, by adjusting the light-emitting surfaces of different optical functional modules, different optical functional modules can share a single modular lens. Regarding focal length, the focal length from the rear light-emitting surface of the high beam module and the low beam module to the lens module is made consistent, thus allowing them to share a single lens module. The focal length of the rear light-emitting surface of the high beam module and the low beam module is designed separately according to their different functions. The design of the signal light module is not significantly affected by focal length and can be achieved by adjusting the diffusion of the rear optical surface. Regarding beam widening, both the high beam module and the low beam module have beam widening design requirements. Therefore, without changing the focal length from the focal point of the high beam module and the low beam module to the lens module, the beam widening design is achieved by tilting the rear light-emitting surfaces of the high beam module and the low beam module, which is equivalent to shifting the focal point.

[0068] 3. This utility model adopts a split design, separating the lens module and the optical function module, which reduces the size of the parts, ensures the optical quality of the parts, and allows different optical function modules to share a single lens, reducing the development of molds.

[0069] 4. This utility model changes the focal point by adjusting the light-emitting surface of the rear optical functional module, thereby achieving optical characteristics for different functions and ensuring the consistency of the general-purpose module lens. Attached Figure Description

[0124] In other embodiments, the low beam module, high beam module, and signal light module are mounted on a rotating frame; the drive assembly can drive the rotating frame to rotate about a horizontal axis, and the switching position is located on the rotation path of the rotating frame; when the rotating frame rotates, the low beam module, high beam module, and signal light module can switch positions. The drive assembly can be a rotary motor or other components capable of rotational drive.

[0125] This embodiment integrates the high and low beams of the vehicle headlights and the signal lights into the same lens module, achieving an optical solution with different functions within the same opening. By leveraging the different characteristics of high and low beams, and considering that the focal length of the high beam is longer than that of the low beam, and that the high beam focal point does not need to be placed near the edge of the total reflection bowl like the low beam focal point, the focal position of the universal module is designed accordingly. That is, the low beam module is designed first, followed by the high beam module design, without affecting the signal lights. Under these conditions, the universal module lens can be fully adapted to the high and low beams and signal light functions. However, because each function requires different module combinations to achieve the optical effects of high beam, low beam, and signal lights, the focal point becomes diverse. Therefore, while keeping the universal module lens unchanged, the light-emitting surfaces of the high and low beam modules and the signal light module are adjusted to meet the design requirements. Furthermore, the versatility of applications is increased through mechanical movement structures, such as moving or rotating the rear end for replacement. Alternatively, multiple modules can be replaced as a whole, and the high and low beams and signal light functions within the same opening can be replaced mechanically by moving up and down.

[0126] Example 2:

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

[0128] This embodiment provides a general modular design for a small-aperture car headlight optical system. The low beam module includes a low beam light source 101, a low beam main beam total reflection bowl 102, a low beam auxiliary beam total reflection bowl 103, a low beam incident lens 104, and a low beam exit lens 105.

[0129] The low beam main beam type total reflection bowl 102 includes a first cutoff region 1021, a second cutoff region 1022, a third cutoff region 1023, and a cutoff inflection point 1024.

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

[0131] The cutoff lines A, B, and C of the low beam type are formed by the first cutoff line region 1021, the second cutoff line region 1022, and the third cutoff line region 1023 of the boundary of the low beam main beam type total internal reflection module 102, and form a D corresponding to the cutoff line inflection point 1024. 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 boundaries of the near-beam auxiliary light pattern total reflection bowl 103: the first three-zone region 1031, the second three-zone region 1032, and the third three-zone region 1033.

[0133] The area of ​​the low beam auxiliary light type total reflection bowl 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 the parts, and improves 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 beam total reflection bowl 202, a high beam entrance lens 204, and a high beam exit lens 205.

[0135] The traffic light module includes a traffic light source 301, a main light type total reflection bowl 302, a traffic light incident lens 303, and a traffic light exiting lens 304. The main light type total reflection bowl 302 can be designed with a diffusion pattern, or the light can be diffused through the traffic light exiting lens module 304.

[0136] The universal modular lens comprises a universal modular lens incident surface 401 and a universal modular lens exit surface 402. Because the focal length of the high beam is designed to be greater than that of the low beam, and the high beam focal point does not need to be placed near the edge of the total reflection bowl like the low beam focal point, the focal length of the universal module lens is based on the low beam module design before the high beam module design; the traffic lights are unaffected. The universal modular lens needs to be fully compatible with high beam, low beam, and traffic light functions, and each function requires different module combinations to achieve the optical effects of high beam, low beam, and traffic lights, resulting in focal point diversity. Therefore, while keeping the universal modular lens unchanged, the light exit surfaces of the high beam, low beam, and traffic light modules are adjusted to meet the design requirements. The number and arrangement of modules are designed according to the different performance and shape requirements of each function, ultimately achieving modular replacement of different functions with the same shape. Different functions can also be achieved within the same opening through an electric structure.

[0137] Furthermore, the focal points of the general-purpose modular lens incident surface 401 and the modular lens exit surface 402 are adjustable in space, horizontally, vertically, and forward and backward, and are not limited to the central optical axis.

[0138] Furthermore, the surface shapes of the low beam output lens 105 and the high beam output lens 205 are adjustable. An angled plane can shift the focal point of the universal module lens to the left or right or up or down; a convex surface can reduce the focal length of the universal module lens; conversely, a concave surface can increase the focal length of the universal module lens; they can also be combined into freeform surfaces to achieve design requirements.

[0139] Furthermore, the surfaces of the low beam output lens 105 and the high beam output lens 205 can be augmented with microstructures to improve road surface uniformity.

[0140] Furthermore, the focal lengths of the low beam main beam total reflection bowl 102, the high beam main beam total reflection bowl 202, and the signal light main beam total reflection bowl 302 can be adjusted according to design requirements (from 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.

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

[0142] Furthermore, the position and shape of the cutoff line area of ​​the low beam main beam 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 plane, a free-form surface, etc.

[0144] Furthermore, the three-zone design on the near beam assist type total reflection bowl 103 area can be an overall segmented pattern, or it can be a separate design for a special area, or other three-zone designs.

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

[0146] Furthermore, the outer surface of the near-beam auxiliary light type total reflection bowl 103 can be textured to reduce stray light in the three zones.

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

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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. 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.

[0152] Furthermore, the signal light source module 301 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.

[0153] Furthermore, the material of this system can be polycarbonate (i.e., PC), polymethyl methacrylate (i.e., PMMA), glass, or silicone.

[0154] Example 3:

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

[0156] More specifically, such as Figure 2 The diagram illustrates the principle of light rays undergoing two refractions in a parallel medium. After two refractions on the parallel medium surface, the light rays will converge with a delay (or the focal length will increase). For example, if light ray S1O1 emerges from the medium, reaches the interface with air, and is refracted into light ray O1O2, then continues forward and reaches the interface with the medium again for a second refraction, finally converging at point S2. If light ray O1O2 does not undergo a second refraction, it converges at point S2'. In this embodiment, the distance between the high / low beam and signal light modules and the general module lens is almost zero, so the effect of the focal length can theoretically be ignored. Figure 3 Schematic diagram of light refraction twice in the vertical direction in a modular system and Figure 4 The diagram illustrates the principle of light refraction twice in the horizontal direction within a modular system. The design does not depict the two refraction states, but only the change in focal length.

[0157] More specifically, such as Figure 5As shown in the schematic diagram of the modular optical system, once the focal length of the near beam system is determined (60mm), the size and optical surface of the universal modular lens can be determined. Therefore, the principle is as follows: light is emitted from the near beam source 101, then converged by the near beam incident lens 104 and enters the component. A portion reaches the near beam principal beam total reflection bowl 102 for total internal reflection into A1A2 rays, and after two refractions by the near beam exit lens 105 and the universal modular lens 6, reaches the universal modular lens exit surface, exiting as A2A3 rays, which then form the near beam principal beam after reaching the 25-meter screen.

[0158] like Figure 7 The optical principle diagram of the modular near-beam optical system is shown. The cutoff lines A, B, and C of the near-beam pattern are formed by the first cutoff region 1021, the second cutoff region 1022, and the third cutoff region 1023 of the boundary of the near-beam main beam total internal reflection module 102, and form D corresponding to the cutoff inflection point 1024. The cutoff line position is adjusted by adjusting the boundary position. Another part reaches the near-beam auxiliary beam total internal reflection bowl 3 for total internal reflection into B1B2 light rays. After two refractions by the light-emitting lens module 105 and the general module lens 6, it reaches the light-emitting surface of the general module lens and is emitted as B2B3 light rays. After reaching the 25-meter screen, it forms a three-zone beam pattern. The three-zone beam patterns E, F, and G 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 near-beam auxiliary beam total internal reflection bowl 103. The increased distance between the low-beam auxiliary light source 1 and the low-beam main light type total internal reflection bowl 2 reduces the thermal risk of components and improves the focal length limit of the total internal reflection bowl. With the focal point of the universal modular lens clearly defined, a high-beam system (30mm rear focal length) can be designed based on this condition, with the optical path as follows... Figure 5 As shown in the diagram. Since the signal light is not affected by focal length, but only by the pattern diffusion angle, the size of the signal light module can be designed arbitrarily. Considering the relationship between uniformity and depth, a longer size is better while maintaining efficiency. The optical path is shown in the diagram. Light enters the signal light module, undergoes total internal reflection (G1G2), and reaches the pattern on the light-emitting surface 304 of the signal light, diffusing into G2G. 31 and G2G 32 After multiple total internal reflections within the universal modular lens, it finally exits onto the 5-meter plane. n1 and G n2 .

[0159] More specifically, the universal modular lens needs to be fully compatible with high beam, low beam, and traffic light functions. Each function requires different module combinations to achieve the optical effects of high beam, low beam, and traffic light, resulting in a variety of focal points. Therefore, while keeping the universal modular lens unchanged, the light-emitting surfaces of the high beam / low beam module and the traffic light module are adjusted to meet the design requirements. For example... Figure 6The diagram illustrates the effect of different surface shapes on the focal position of a modular lens. An angled plane can shift the focal point of a general-purpose modular lens to the left or right or up or down; a convex surface can reduce the focal length of a general-purpose modular lens; conversely, a concave surface can increase the focal length of a general-purpose modular lens; similarly, they can be combined into freeform surfaces to achieve design requirements.

[0160] More specifically, such as Figure 8 and Figure 9 As shown, because the low beam spot requires high brightness, it is centered while having a longer focal length and a more focused beam pattern. Conversely, if the low beam is widened, the focal length is shorter, and the beam pattern is more diffused. Figure 8 The schematic diagram of the modular low beam optical system and the schematic diagram of the low beam patterns of the nine different modules are shown. The left and right position of the focal point after deflection by the light-emitting lens module 5.1 also affects the optical design. When the focal point is in the center position (module 1.1), the beam pattern is centered (beam pattern 1.1), which is used for the low beam bright spot design. When the focal point deviates from the center position (module 2.1), the beam pattern also deviates from the center (beam pattern 2.1), which is used for the low beam broadening design. And so on, after the focal point deviates from the center position, the corresponding beam patterns 3.1, 4.1, and 5.1 are formed. Finally, all the beam patterns are combined to form the low beam pattern. Then, according to the performance requirements, the required number of different modules is determined and arranged according to the shape requirements.

[0161] More specifically, such as Figure 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 focused beam pattern. Conversely, if the low beam is designed to be wider, the focal length is smaller and the beam pattern is more diffused. The left and right positions of the focal point of the light-emitting lens module 5.2 also affect the optical design. When the focal point is in the center position (modules 1.2 and 3.2), the beam pattern is centered (beam pattern 1.2 and beam 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 beam pattern will also be off-center (beam pattern 2.2 and beam pattern 4.2), used for the high beam widening design. And so on, different beam patterns are formed after the focal point is shifted from the center. Finally, all beam patterns are combined to form the high beam pattern. Then, according to the performance requirements, the required number of different modules is determined and arranged according to the design requirements.

[0162] More specifically, such as Figure 11 Within the same universal module lens opening, different functions are achieved through an electric mechanism, such as moving or rotating the rear end. Multiple modules can be used to replace each other's functions, and within the same opening, the high / low beam and signal light functions can be replaced by mechanical means such as moving up and down. In the diagram, a represents horizontal movement, c represents vertical movement, and b represents rotation.

[0163] Figure 3 and Figure 4In this context, A represents the light-emitting lens module of the low beam module, high beam module, or traffic light module.

[0164] This invention achieves a multi-functional design and ensures a consistent shape by using the same universal modular lens.

[0165] The light source of this invention is a surface-mount LED, which is integrated on the PCBA or on the heat sink and connected to the PCB board by metal wires. In other embodiments, other light source types can be selected according to actual needs.

[0166] This invention can be configured to generate multiple light distributions, each of which is of a different type.
