[0051] Embodiment 1:
[0052] As shown in Figures 1-10, this embodiment provides a multifunctional matrix high beam and projection module, including: a lens body, a light source module 1, a main light type total reflection module 2, a light input lens module 3 and a projection light type total reflection module 5 are arranged at the light input end of the lens body, and a light output lens module 4 is arranged at the light output end of the lens body; the main light type total reflection module 2 includes a plurality of pixel total reflection modules 201 arranged in an array, the light source module 1 includes a plurality of main light type light source modules 101, the light input lens module 3 includes a plurality of main light type light input lens modules 301, and the main light The main light source module 101, the main light incident lens module 301 and the pixel total reflection module 201 are arranged in a one-to-one correspondence; the projection light type total reflection module 5 includes a plurality of projection total reflection modules 501, and the plurality of projection total reflection modules 501 are distributed on both sides of the main light type total reflection module 2; the light source module 1 also includes a plurality of projection light source modules 102, and the incident lens module 3 also includes a plurality of projection incident light lens modules 302, and the projection light source module 102, the projection incident light lens module 302 and the projection total reflection module 501 are arranged in a one-to-one correspondence.
[0053] The projection total reflection module 501 is placed on both sides, which will not affect the performance of the matrix high beam. The design principles of the matrix high beam and the projection are similar, except that the imaging position and road surface requirements are different, so the light propagation paths are similar.
[0054] The light-emitting lens module 4 has two focal points: one focal point is located at a position where a matrix high-beam light pattern is formed, and the other focal point is located at a boundary of the main light pattern total reflection module 2 .
[0055] The light emitted from the main light source module 101 enters the lens body through the main light incident lens module 301, reaches the pixel total reflection module 201 for total reflection, and is emitted through the light emitting lens module 4 to form a matrix high beam light type; the light emitted from the projection light source module 102 enters the lens body through the projection light incident lens module 302, reaches the projection total reflection module 502 for total reflection, and is emitted through the light emitting lens module 4 to form a projection pattern. The pixel total reflection module 201 is located below the main light incident lens module 301, and the light incident direction of the main light source module 101 is from top to bottom; the projection total reflection module 501 is located below the projection light incident lens module 302, and the light incident direction of the projection light source module 102 is from top to bottom; the lens focus of the light emitting lens module 4 is located below the optical axis of the lens body.
[0056] The outer surface of the pixel total reflection module 201 is plated with an aluminum layer. The pattern outer surface of the projection total reflection module 501 is plated with an aluminum layer. The non-pattern outer surface of the projection total reflection module 501 is provided with leather grain. The surface of the light-emitting lens module 4 is provided with a microstructure. The main light source module 101 is any one of the following: single chip, multi-chip, SMD LED, laser light source, RGB light source; the projection light source module 102 is any one of the following: single chip, multi-chip, SMD LED, laser light source, RGB LED. The material of the lens body is any one of the following: polycarbonate, polymethyl methacrylate, glass or silicone.
[0057] When the main light source module 101 is a SMD LED, it can be set in any of the following ways:
[0058] Method 1: SMD LED is integrated on PCBA board;
[0059] Method 2: The SMD LED is integrated on the heat sink and connected to the PCBA board through metal wires.

[0064] In this embodiment, the projection light source module 102 is a SMD LED. In other embodiments, other light source types may be selected according to actual needs.
[0065] This embodiment optimizes the traditional optical system to achieve a small-opening matrix high beam and projection module design, which only has a light incident surface, a total reflection surface and a light exit surface. The matrix high beam and projection optical system includes a light incident lens module, a matrix light type total reflection module, a projection light type total reflection module and a light exit lens module, and is equipped with a group of light source modules to form a matrix high beam and projection optical system. At the same time, it can also be split to realize the matrix high beam or projection function. The LED of this matrix high beam and projection system is incident from top to bottom, and the lens focus is under the optical axis, which can increase the utilization rate of the optical surface and improve the light exit efficiency. At the same time, the light incident lens module improves the light incident efficiency, so that the overall efficiency of this system is greatly improved compared to the traditional optical system. The matrix high beam and projection system module can simultaneously realize pixelated matrix high beam and basic vehicle projection functions, which can assist the driver in driving safely.
[0066] This embodiment adjusts the upper and lower positions of the projection module and the light-emitting lens focus to achieve the multi-functional module sharing the same light-emitting lens module, thereby solving the difference between the target distance and projection distance of the matrix high beam. The integrated design of parts and functions reduces the tolerance of the dimension chain, improves the stability of the optical system, and reduces the cost of the module.
[0067] Embodiment 2:
[0068] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.
[0069] The present embodiment provides a module design of a minimalist multifunctional matrix high beam and projection system, including a light source module 1, a main light type total reflection module 2, an incident light lens module 3, a light output lens module 4, and a projection light type total reflection module 5.
[0070] The main light type total reflection module 2 includes a plurality of pixel total reflection modules 201, and the number and pattern of the projection light type total reflection modules 5 can be designed according to customer requirements. The light of the matrix high beam module is emitted from the main light type light source module 101 of the light source module 1, and then converged by the main light type light incident lens module 301 of the light incident lens module 3 and enters the part. A part reaches the pixel total reflection module 201 of the main light type total reflection module 2 and is totally reflected into A1A2 light, and is emitted into A2A3 light through the light emitting lens module 4. At the same time, it is totally reflected into B1B2 light at the pixel total reflection module 201 of the main light type total reflection module 2, and is emitted into B2B3 light through the light emitting lens module 4 to form a matrix high beam light type after reaching the 25-meter screen.
[0071] The light of the projection module is emitted from the projection light source module 102 of the light source module 1, and then converged by the projection light input lens module 302 of the light input lens module 3 and enters the part. A part reaches the projection total reflection module 501 of the projection light type total reflection module 5 and is totally reflected into C1C2 light, and is emitted into C2C3 light through the light output lens module 4. At the same time, it is totally reflected at the projection total reflection module 501 of the projection light type total reflection module 5 into D1D2 light, and is emitted into D2D3 light through the light output lens module 4 to form a projection pattern.
[0072] The two focal points of the light-emitting lens module 4 are designed, one (F') is at 25 meters (regulatory requirements), and the other (F1) is at the upper boundary of the main light type total reflection module 2 (focal length is within 100mm), and its front and rear positions are within ±5mm, and the upper and lower positions are also at the upper boundary of the main light type total reflection module 2, and its upper and lower positions are within ±5mm. There is no restriction on the left and right positions, and it can be designed according to the field of view of the target light type. Because the same light-emitting lens module 4 is shared, the matrix high beam target is designed at 25m, and the projection is about 5m in front of the car, so it can be achieved through the pattern of the projection light type total reflection module 5 and the upper and lower positions of the focus of the light-emitting lens module 4. At the same time, it can also be split according to design requirements to realize the matrix high beam or projection function.
[0073] Furthermore, the focal length of the main light type total reflection module 2 can be adjusted according to design requirements (1mm to 5mm). The smaller the focal length, the more focused the light type and the larger the maximum value. Conversely, the more dispersed the light type and the smaller the maximum value.
[0074] Furthermore, the outer surface of the main light type total reflection module 2 can be plated with aluminum, thereby reducing light loss and improving optical efficiency.
[0075] Furthermore, the pattern of the projection light type total reflection module 5 can be designed according to requirements, and the projection system can be designed as a replaceable module for arbitrary replacement.
[0076] Furthermore, the position of the projection light type total reflection module 5 can be designed according to requirements. When there is a matrix high beam function at the same time, it is recommended to place it on both sides of the module without affecting the matrix high beam function; when it is split separately to realize the projection module function, the pattern position can be arranged at will.
[0077] Furthermore, the pattern outer surface of the projection light type total reflection module 5 can be plated with aluminum, thereby reducing light loss and improving optical efficiency.
[0078] Furthermore, the outer surface of the projection light type total reflection module 5 except for the pattern may be provided with skin texture, so as to reduce the influence of stray light.
[0079] Furthermore, the surface shape of the light-input lens module 3 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.
[0080] Furthermore, the focal length of the light-emitting lens module 4, that is, the distance to the main light type total reflection module 2 is adjustable. The smaller the distance, the higher the efficiency, the more scattered the light type, and the smaller the resolution. Conversely, the larger the distance, the lower the efficiency, the more focused the light type, and the greater the resolution.
[0081] Furthermore, a microstructure may be added to the surface of the light output lens module 5 to improve the uniformity of the road surface.
[0082] Furthermore, the light source module 1 can be a single chip, a multi-chip or a SMD LED or a laser light source or an RGB light source. The projection light source module 1012 can also be an RGB LED.
[0083] Further, the light source module 1 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.
[0084] Furthermore, the material of the system may be polycarbonate (ie PC) or polymethyl methacrylate (ie PMMA) or glass or silicone (ie Silicon).
[0085] Embodiment 3:
[0086] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.
[0087] More specifically, the high beam module opening is designed as a 40mmx25mm thick-walled piece, with 11 pixels of the same angle, and a field of view of ±13 degrees. Figure 1 The module view of the minimalist multifunctional matrix high beam and projection system and Figure 8 As shown in the schematic diagram of the projection module of the minimalist multifunctional matrix high beam module, the module design of the multifunctional matrix high beam and projection system of this embodiment includes a light source module 1, a main light type total reflection module 2, an input light lens module 3, an output light lens module 4, and a projection light type total reflection module 5.
[0088] The main light type total reflection module 2 includes a pixel total reflection module 201; the number and pattern of the projection light type total reflection module 5 can be designed according to customer requirements. Figure 2 The minimalist multifunctional matrix high beam module top view and AA section view, Figure 3 The minimalist multifunctional matrix high beam module optical schematic diagram and Fig. 9 Optical schematic diagram of the minimalist multifunctional matrix high beam projection module Fig. 9 .1 as shown.
[0089] The light of the matrix high beam module is emitted from the light source module 1, and then converged by the light input lens module 3 and enters the part. A part reaches the main light type total reflection module 2 and is totally reflected into A1A2 light, and is emitted as A2A3 light through the light output lens module 4. At the same time, it is totally reflected from the main light type total reflection module 2 into B1B2 light, and is emitted as B2B3 light through the light output lens module 4 to form a matrix high beam light type after reaching the 25-meter screen.
[0090] The light of the projection module is emitted from the light source module 1, and then converged by the light input lens module 3 and enters the part. A part reaches the main light type total reflection module 2 and is totally reflected into C1C2 light, and is emitted as C2C3 light through the light output lens module 4. At the same time, it is totally reflected with the main light type total reflection module 2 to form D1D2 light, and is emitted as D2D3 light through the light output lens module 4 to form a projection pattern.
[0091] The two focal points of the light-emitting lens module 4 are designed, one (F') is at 25 meters (regulatory requirements), and the other (F1) is at the upper boundary of the main light type total reflection module 2 (focal length is within 100mm), and its front and rear positions are within ±5mm, and the upper and lower positions are also at the upper boundary of the main light type total reflection module 2, and its upper and lower positions are within ±5mm. There is no restriction on the left and right positions, and it can be designed according to the field of view of the target light type. Because the same light-emitting lens module 4 is shared, the matrix high beam target is designed at 25m, and the projection is about 10m in front of the vehicle, so it can be achieved by adjusting the pattern of the projection total reflection module 5 and the upper and lower positions of the focus of the light-emitting lens module 5. At the same time, it can also be split according to design requirements to realize the matrix high beam or projection function.
[0092] More specifically, since the matrix high beam has both brightness requirements (above 100lx) and resolution requirements, the design of the light-emitting lens module needs to take into account the performance of both. This design is shown in the schematic diagram of the influence of different lens focal lengths of the minimalist multifunctional matrix high beam module in Figure 4. The focal length of the light-emitting lens module 4 can be adjusted. If the focal length L2 of module 2 is small (80mm), the corresponding result light type 2 has a higher efficiency, a wider light type, and a smaller maximum value, which can be used as a light type design with a lower resolution. On the contrary, if the focal length L1 of module 1 is large (100mm), the corresponding result light type 1 has a lower efficiency, a more concentrated light type, and a larger maximum value, which can be used as a light type design with a higher resolution.
[0093] More specifically, the size and arrangement of the pixels of the matrix high beam are designed as follows: Figure 5 As shown in the diagram of the pixel arrangement structure of the minimalist multifunctional matrix high beam module, the pixel angle in the central area has a higher resolution requirement, so the pixel size needs to be designed to be smaller. The pixel angle away from the center area has a lower requirement, so the pixel size can be designed to be larger, and the angles of all pixels can be specially designed according to requirements. At the same time, the number of pixels of the matrix high beam can also be designed according to requirements. The more pixels, the greater the resolution within the same field of view, and the higher the cost. Conversely, the smaller the resolution, the lower the cost. The light type position of each pixel and its corresponding relationship are shown in the figure. Figure 6 The minimalist multifunctional matrix high beam module pixel arrangement is shown in the light pattern diagram.
[0094] More specifically, the light type and lighting mode of a single pixel in this embodiment are as follows: Figure 7 The optical performance and mode diagram of the minimalist multifunctional matrix high beam module with a 40mmx25mm opening, the angle of a single lit pixel is ±1.9 degrees, and the field of view is ±13 degrees. As shown in Mode 1-Mode 6, this embodiment can achieve a resolution of 1.9 degrees (dark area angle), meeting the basic matrix high beam design requirements. In addition, through actual road scene analysis, more application scenario modes are designed using software control to assist drivers in driving safely.
[0095] More specifically, Figure 8 The projection module diagram of the minimalist multifunctional matrix high beam module and Fig. 9 The optical principle of the minimalist multifunctional matrix high beam projection module Fig. 9 As shown in .2, the pattern of the projection light type total reflection module 5 is far away from the focus. Because it needs to be projected in front of the vehicle, when designing the matrix high beam, the focus of the light-emitting lens module is relatively low, so that the projection pattern is offset upward. The closer to the light source module, the closer the projected pattern is to the front of the vehicle. The projection pattern can be designed according to requirements, and can be left and right arrows, zebra crossings, etc., so that it can provide warning information to the surrounding area of the vehicle when driving or parking, informing others that they need to turn, wait for the bus, etc., making driving safer. Fig.10 As shown, the projection system can be designed as a replaceable module and can be replaced at will. The position of the projection light type total reflection module 5 can be designed according to requirements. When there is a matrix high beam function at the same time, it is recommended to place it on both sides of the module, such as Figure 8 .1, does not affect the matrix high beam function; its projection pattern is as follows Figure 8 .2-8.4. When the projection module is separated to realize the function, the pattern position can be arranged at will.
[0096] In this embodiment, the light source is set as a SMD LED, which is integrated on the PCBA or integrated on the heat sink and connected to the PCB board through metal wires. In other embodiments, other light source types can be selected according to actual needs. It can also be a single chip, multi-chip or laser light source;
[0097] The present embodiment can be configured to generate a plurality of light distributions, the types of the plurality of light distributions being different, and the type of each light distribution being any one of the following: low beam lighting, high beam lighting, adaptive low beam lighting, ADB high beam lighting, corner fog lamp lighting, city road mode lighting, country 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.
[0098] The present invention solves the difference between the target distance and the projection distance of the matrix high beam and realizes the multiplexing of the matrix high beam and the projection function.
[0099] The present invention can be configured to generate multiple light distributions, the types of which are different, and each light distribution type is any one of the following: low beam lighting, high beam lighting, adaptive low beam lighting, ADB high beam lighting, corner fog lamp lighting, urban road mode lighting, country road mode lighting, highway mode lighting, bend mode lighting, rain and fog mode lighting, position signal lights, turn signal lights, daytime running lights, welcome lights, ambient lights, etc.
