[0050] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0051] Example 1:
[0052] As shown in 1-10, this embodiment provides a multifunctional matrix high beam and projection module, including: a lens body, with a light source module 1, a main beam total internal reflection module 2, a light incident lens module 3, and a projection beam total internal reflection module 5 disposed at the light incident end of the lens body, and a light exiting lens module 4 disposed at the light exiting end of the lens body; the main beam total internal reflection module 2 includes multiple pixel total internal reflection modules 201 arranged in an array, the light source module 1 includes multiple main beam light source modules 101, the light incident lens module 3 includes multiple main beam light incident lens modules 301, and the main beam... The light source module 101, the main light type incident lens module 301, and the pixel total internal reflection module 201 are arranged in a one-to-one correspondence; the projection light type total internal reflection module 5 includes multiple projection total internal reflection modules 501, which are distributed on both sides of the main light type total internal reflection module 2; the light source module 1 also includes multiple projection light source modules 102, and the incident lens module 3 also includes multiple projection incident lens modules 302, with the projection light source module 102, the projection incident lens module 302, and the projection total internal reflection module 501 arranged in a one-to-one correspondence.
[0053] The projection total internal reflection module 501 is placed on both sides, which will not affect the performance of the matrix high beam. The design principles of matrix high beam and projection are similar, only the imaging position and road surface requirements are different, so the light propagation path is similar.
[0054] The light-emitting lens module 4 has two focal points: one focal point is located at the position that forms the matrix far beam pattern, and the other focal point is located at the boundary of the main beam pattern total internal reflection module 2.
[0055] Light emitted from the main light source module 101 enters the lens body through the main light source lens module 301, undergoes total internal reflection at the pixel total internal reflection module 201, and exits through the light exiting lens module 4 to form a matrix far-beam pattern. Light emitted from the projection light source module 102 enters the lens body through the projection light source lens module 302, undergoes total internal reflection at the projection total internal reflection module 502, and exits through the light exiting lens module 4 to form a projected pattern. The pixel total internal reflection module 201 is located below the main light source lens module 301, and the light incident direction of the main light source module 101 is from top to bottom. The projection total internal reflection module 501 is located below the projection light source lens module 302, and the light incident direction of the projection light source module 102 is from top to bottom. The focal point of the light exiting lens module 4 is located below the optical axis of the lens body.
[0056] The outer surface of the pixel total internal reflection module 201 is coated with an aluminum layer. The patterned outer surface of the projection total internal reflection module 501 is coated with an aluminum layer. The non-patterned outer surface of the projection total internal reflection module 501 is textured. The surface of the light-emitting lens module 4 is provided with microstructures. The main light source module 101 is any one of the following: single-chip, multi-chip, surface-mount LED, laser light source, RGB light source; the projection light source module 102 is any one of the following: single-chip, multi-chip, surface-mount LED, laser light source, RGB LED. The lens body is made of any one of the following materials: polycarbonate, polymethyl methacrylate, glass, or silicone.
[0057] When the main light source module 101 is a surface-mount LED, it can be set in any of the following ways:
[0058] Method 1: Surface mount LEDs are integrated onto the PCBA board;
[0059] Method 2: Surface mount LEDs are integrated onto the heat sink and connected to the PCBA board via metal wires.
[0060] In this embodiment, the main light source module 101 is a surface-mount LED. In other embodiments, other light source types can be selected according to actual needs.
[0061] When the projection light source module 102 is a surface-mount LED, it can be set in any of the following ways:
[0062] Method 1: Surface mount LEDs are integrated onto the PCBA board;
[0063] Method 2: Surface mount LEDs are integrated onto the heat sink and connected to the PCBA board via metal wires.
[0064] In this embodiment, the projection light source module 102 is a surface-mount LED. In other embodiments, other light source types can be selected according to actual needs.
[0065] This embodiment optimizes a traditional optical system to achieve a small-aperture matrix high-beam and projection module design, featuring only an incident light surface, a total internal reflection surface, and an exit light surface. The matrix high-beam and projection optical system includes an incident lens module, a matrix beam total internal reflection module, a projection beam total internal reflection module, and an exit light lens module, along with a set of light source modules. It can also be split to implement either matrix high-beam or projection functions. In this matrix high-beam and projection system, the LEDs receive light from above, and the lens focal point is below the optical axis, increasing the utilization of the optical surface and improving optical efficiency. Simultaneously, the incident lens module enhances the incident light efficiency, resulting in a significant improvement in overall system efficiency compared to traditional optical systems. The matrix high-beam and projection system module can simultaneously achieve pixelated matrix high-beam and basic automotive projection functions, assisting drivers in safe driving.
[0066] This embodiment achieves the sharing of the same light-emitting lens module across multiple modules by adjusting the vertical position of the projection module and the focal point of the light-emitting lens, thus resolving the difference between the target distance and the projection distance of the matrix far-beam. The integrated design of components and functions reduces dimensional tolerances, improves the stability of the optical system, and lowers the cost of the module.
[0067] Example 2:
[0068] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.
[0069] This embodiment provides a simplified module design for a multi-functional matrix high beam and projection system, including a light source module 1, a main light type total internal reflection module 2, an incident light lens module 3, an exit light lens module 4, and a projection light type total internal reflection module 5.
[0070] The main light type total internal reflection module 2 includes multiple pixel total internal reflection modules 201. The number and pattern of the projection light type total internal reflection modules 5 can be designed according to customer requirements. The light from 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 source lens module 301 of the light source lens module 3 before entering the component. A portion of the light reaches the pixel total internal reflection module 201 of the main light type total internal reflection module 2 and undergoes total internal reflection into light rays A1A2, which are then emitted into light rays A2A3 through the light output lens module 4. Simultaneously, light rays undergo total internal reflection at the pixel total internal reflection module 201 of the main light type total internal reflection module 2, becoming light rays B1B2, which are then emitted into light rays B2B3 through the light output lens module 4. After reaching the 25-meter screen, these light rays form the matrix high beam pattern.
[0071] The light from 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 entrance lens module 302 of the light entrance lens module 3 before entering the component. A portion of the light reaches the projection total internal reflection module 501 of the projection light pattern total internal reflection module 5 and undergoes total internal reflection into C1C2 light rays, which are then emitted as C2C3 light rays through the light exit lens module 4. Simultaneously, light rays undergo total internal reflection at the projection total internal reflection module 501 of the projection light pattern total internal reflection module 5 and are converted into D1D2 light rays, which are then emitted as D2D3 light rays through the light exit lens module 4 to form the projection pattern.
[0072] The two focal points of the light-emitting lens module 4 are designed as follows: one (F') is at 25 meters (as required by regulations), and the other (F1) is at the upper boundary of the main light-type total internal reflection module 2 (within a focal length of 100mm). Their front-to-back and vertical positions are both within ±5mm, also within ±5mm, and are located at the upper boundary of the main light-type total internal reflection module 2. The left-to-right position is not restricted and can be designed according to the field of view of the target beam pattern. Because the same light-emitting lens module 4 is shared, the matrix high beam target is designed at 25m, while the projection is approximately 5m in front of the vehicle. Therefore, this can be achieved by using the pattern of the projection beam pattern total internal reflection module 5 and the vertical position of the focal point of the light-emitting lens module 4. Alternatively, the matrix high beam or projection functions can be implemented separately according to design requirements.
[0073] Furthermore, the focal length of the main light type total internal reflection module 2 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.
[0074] Furthermore, the outer surface of the main light type total internal reflection module 2 can be plated with aluminum, thereby reducing light loss and improving optical efficiency.
[0075] Furthermore, the pattern of the projection light pattern total internal reflection module 5 can be designed according to requirements, and the projection system can be designed as a replaceable module that can be freely replaced.
[0076] Furthermore, the position of the projection light pattern total reflection module 5 can be designed according to requirements. When the matrix high beam function is also present, it is recommended to place it on both sides of the module so as not to affect the matrix high beam function. When the projection module function is implemented separately, the pattern position can be arranged arbitrarily.
[0077] Furthermore, the outer surface of the pattern of the projection light pattern total internal 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 pattern total internal reflection module 5, in addition to the pattern, can be textured to reduce the influence of stray light.
[0079] Furthermore, the surface shape of the light-incident lens module 3 can be adjusted according to design requirements. It can converge or diverge light, and the size of its convergence or divergence can also be adjusted by the surface shape.
[0080] Furthermore, the focal length of the light-emitting lens module 4, i.e. the distance to the main light type total internal reflection module 2, can be adjusted. The smaller the distance, the higher the efficiency, the more diffused the light pattern, and the lower the resolution. Conversely, the larger the distance, the lower the efficiency, the more focused the light pattern, and the higher the resolution.
[0081] Furthermore, the surface of the light-emitting lens module 5 can be augmented with microstructures to improve road surface uniformity.
[0082] Furthermore, the light source module 1 can be a single-chip, multi-chip, or surface-mount LED, laser, or RGB light source. The projection light source module 1012 can also be an RGB LED.
[0083] Furthermore, the light source module 1 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.
[0084] Furthermore, the material of this system can be polycarbonate (i.e., PC), polymethyl methacrylate (i.e., PMMA), glass, or silicone.
[0085] Example 3:
[0086] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.
[0087] More specifically, this high beam module features a 40mm x 25mm thick-walled design with 11 pixels at the same angle, providing a field of view of ±13 degrees. For example... Figure 1 A minimalist, multi-functional matrix high beam and projection system module view and Figure 8 The schematic diagram of the projection module of the minimalist multi-functional matrix high beam module is shown. The module design of the multi-functional matrix high beam and projection system in this embodiment includes a light source module 1, a main light type total internal reflection module 2, an incident light lens module 3, an exit light lens module 4, and a projection light type total internal reflection module 5.
[0088] The main light type total internal reflection module 2 includes a pixel total internal reflection module 201; the number and pattern of the projection light type total internal reflection modules 5 can be designed according to customer requirements. For example... Figure 2 A minimalist top view and AA cross-sectional view of the multi-functional matrix high beam module. Figure 3 A minimalist optical schematic of a multi-functional matrix high beam module and Figure 9 A minimalist, multi-functional matrix projection module optical principle diagram Figure 9 As shown in .1.
[0089] The light rays from the matrix high beam module are emitted from the light source module 1, then converged by the incident lens module 3 and enter the component. A portion reaches the main beam total internal reflection module 2 for total internal reflection into light rays A1A2, and is then emitted as light rays A2A3 through the exiting lens module 4. Simultaneously, light rays are also total internally reflected by the main beam total internal reflection module 2 into light rays B1B2, and then emitted as light rays B2B3 through the exiting lens module 4, forming the matrix high beam pattern after reaching the 25-meter screen.
[0090] The light emitted from the light source module 1 is then converged by the incident lens module 3 and enters the component. A portion of the light reaches the main light type total internal reflection module 2 and undergoes total internal reflection into C1C2 light rays, which are then emitted as C2C3 light rays through the exiting lens module 4. Simultaneously, light rays undergo total internal reflection at the main light type total internal reflection module 2 into D1D2 light rays, which are then emitted as D2D3 light rays through the exiting lens module 4 to form the projected pattern.
[0091] The light-emitting lens module 4 has two focal points: one (F') at 25 meters (as required by regulations), and the other (F1) at the upper boundary of the main beam total internal reflection module 2 (within a focal length of 100mm). Their front-to-back and vertical positions are both within ±5mm, also within ±5mm of the upper boundary of the main beam total internal reflection module 2. The left-to-right position is not restricted and can be designed according to the field of view of the target beam pattern. Because the same light-emitting lens module 4 is used, the matrix high beam target is designed at 25m, while the projection is approximately 10m in front of the vehicle. Therefore, this can be achieved by adjusting the pattern of the projection total internal reflection module 5 and the vertical position of the focal point of the light-emitting lens module 5. Alternatively, the matrix high beam or projection functions can be implemented separately according to design requirements.
[0092] More specifically, since matrix high beams require both brightness (above 100 lx) and resolution, the design of the output lens module needs to consider the performance of both. Figure 4 shows a simplified schematic diagram of the influence of different lens focal lengths on the multi-functional matrix high beam module. The focal length of the output lens module 4 is adjustable. For example, if the focal length L2 of module 2 is smaller (80 mm), the resulting beam pattern 2 has higher efficiency, a wider beam pattern, and a smaller maximum value, making it suitable for lower resolution beam pattern designs. Conversely, if the focal length L1 of module 1 is larger (100 mm), the resulting beam pattern 1 has lower efficiency, a more focused beam pattern, and a larger maximum value, making it suitable for higher resolution beam pattern designs.
[0093] More specifically, the pixel size and arrangement design of the matrix high beam are as follows: Figure 5 The simplified pixel arrangement diagram of the multi-functional matrix high beam module is shown. Due to the high resolution requirements, the pixel size in the central area needs to be designed to be smaller. Pixels further away from the center have lower resolution requirements, so their pixel size can be designed to be larger. Furthermore, the angles of all pixels can be custom-designed according to requirements. The number of pixels in the matrix high beam can also be designed according to requirements; a higher number of pixels results in higher resolution within the same field of view, but also higher cost, and vice versa. The light pattern position of each pixel and its corresponding relationship are shown below. Figure 6 The pixel arrangement light pattern diagram of the minimalist multi-functional matrix high beam module is shown.
[0094] More specifically, the light pattern and illumination mode of a single pixel in this embodiment are as follows: Figure 7 The diagram illustrates the optical performance and modes of a minimalist, multi-functional matrix high-beam module with a 40mm x 25mm aperture. The angle of a single illuminated pixel is ±1.9 degrees, and the field of view is ±13 degrees. As shown in modes 1-6, this embodiment achieves a resolution (dark area angle) of 1.9 degrees, meeting the basic design requirements of a matrix high-beam module. Furthermore, through analysis of actual road scenarios, software control is used to design more application scenario modes to assist drivers in safe driving.
[0095] More specifically, Figure 8 A simplified schematic diagram of the projection module of a multi-functional matrix high beam module and such Figure 9 The minimalist, multi-functional matrix projection module's optical principle for high beams. Figure 9 As shown in Figure 2, the pattern of the total internal reflection module 5 is far from the focal point because it needs to be projected onto the front of the vehicle. Therefore, when designing the matrix high beam, the focal point of the light-emitting lens module is relatively low, causing the projection pattern to shift upwards. The closer the pattern is to the light source module, the closer it is to the front of the vehicle. The projection pattern can be designed according to requirements, such as left and right arrows, zebra crossings, etc. This can provide warning information to the surrounding area when driving or parking, informing others that they need to turn or wait for a vehicle, making driving safer. Figure 10 As shown, the projection system can be designed with replaceable modules for easy replacement. The position of the projection beam total reflection module 5 can be designed according to requirements. When matrix high-beam functionality is also required, it is recommended to place it on both sides of the module, such as... Figure 8 0.1, does not affect the matrix high beam function; its projection pattern is as follows Figure 8 As shown in .2-8.4. When the projection module function is implemented separately, the pattern position can be arranged arbitrarily.
[0096] 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.
[0097] 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.
[0098] This invention solves the difference between the target distance and the projection distance of matrix high beam, and realizes the reuse of matrix high beam and projection functions.
