[0036] Detailed implementation manners

[0037] The present utility model will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made. These all fall within the protection scope of the present utility model.

[0038] The utility model discloses a replaceable modular lens module structure, which modularizes the traditional lens module. Under the same lens, lens bracket and radiator, multiple light source sub-modules are provided, and multiple reflector bowl sub-modules or multiple condenser sub-modules are provided. Each light source sub-module includes an auxiliary radiator and a light source (LED light source module and laser light source module). The overall light source module, reflector bowl module and condenser module are replaced according to different requirements, or only the light source (LED light source module and laser light source module) is replaced, or only the reflector bowl module is replaced, or only the condenser module is replaced. At the same time, the same module can be used for different functions (high beam and low beam, ABD), so as to meet the requirements of different customers and reduce the cost of the module.

[0039] Specifically, the utility model discloses a replaceable modular lens module structure, which includes a lens 1, a lens bracket 2, a main radiator 3, a light source module 4, a light ray adjusting module, and a cut-off line baffle 7. The light ray adjusting module includes any one or more of a reflector bowl module 5 and a condenser module 6. The light rays emitted by the light source module 4 are converged and adjusted by the light ray adjusting module and then emitted from the lens. The lens 1 is fixedly installed through the lens bracket 2. The light source module 4 is connected to the main radiator 3 to ensure that the heat generated during the operation of the light source module 4 is dissipated in time.

[0040] The cut-off line baffle 7 is used for the low beam optical system to form a low beam light pattern when emitting light. The light rays emitted from the light source module 4 converge at the focal point on the inner surface of the lens 1. A part of the light rays reach the inner surface of the lens 1 below the center line through the low beam cut-off line baffle 7 placed at the inner surface focal point, propagate inside the lens 1 to the outer surface of the lens 1, and then converge upward to the focal point on the outer surface of the lens 1 to form the required light pattern on the focal plane. Another part of the stray light is blocked by the cut-off line baffle 7 in front of the focal point and is reflected by the reflective upper surface. The light rays reach the inner surface of the lens 1 on the center line, enter the lens 1, propagate to the outer surface of the lens 1, converge downward to the focal point on the outer surface of the lens 1, and also form a light pattern on the focal plane, which coincides with the main light pattern to form a low beam.

[0041] The lens 1 includes multiple lens sub-modules, the light source module 4 includes multiple light source sub-modules, the reflector bowl module 5 includes multiple reflector bowl sub-modules, and the condenser module 6 includes multiple condenser sub-modules.

[0042] Among them, multiple lens sub-modules of lens 1 respectively correspond one-to-one to the light source module 4 and the reflector bowl module 5 at the back end. For example: the light source module 4 includes multiple light source sub-modules such as 4.1 - 4.5. Each light source sub-module includes a small L-shaped auxiliary radiator and a light source (LED light source module and laser light source module). The reflector bowl 5 includes multiple reflector bowl sub-modules such as 5.1 - 5.5. The condenser module 6 includes multiple condenser sub-modules with different designs. According to different design requirements, each light source sub-module can correspond to a different reflector bowl sub-module or condenser sub-module. After multiple light source sub-modules are matched with corresponding reflector bowl sub-modules or condenser sub-modules, they are finally installed on the main radiator 3 to form the module light source end.

[0043] For the high beam system, light rays are emitted from the LED or laser on the light source module 4, converge to the corresponding area of lens 1 through the corresponding reflector bowl module 5 or condenser module 6, and finally exit to form the high beam light pattern. Similarly, for the low beam system, light rays are emitted from the LED or laser on the light source module 4, converge to the corresponding cut-off line baffle 7 through the corresponding reflector bowl module 5 or condenser module 6 and then pass through the corresponding area of lens 1, and finally exit to form the low beam light pattern.

[0044] In a preferred embodiment, the contact surface between the main radiator 3 and the auxiliary radiator of the light source module 4 is designed in an L shape, taking into account the existing laser light source module, thus realizing the random replacement of two different types of light sources.

[0045] In a preferred embodiment, the number of partitions of lens 1, the light source module, the reflector bowl module, and the condenser module can be designed differently according to different design requirements; the multiple partition positions of lens 1 can be replaced with each other. For example: the same area of lens 1 can be matched with different light source modules 4, reflector bowl modules 5, or condenser modules 6. The material of lens 1 can be polycarbonate (i.e., PC) or polymethyl methacrylate (i.e., PMMA) or glass.

[0046] The auxiliary radiators of the light source module 4 can be designed to be the same size or different sizes, and the materials of the radiators of the light source module 4 can be designed to be the same or different.

[0047] In the light source module 4, the number of light sources on each light source sub-module can be different to meet different light intensity requirements. For example: the number of LED chips (single chip or multiple chips) and the number of pieces can be different; the type of light source on each light source sub-module can also be different. For example, the types of LEDs can be ordinary LEDs, top contact LEDs, or laser LEDs, etc.

[0048] In this embodiment, the light source is set as a surface-mounted LED, which is integrated on the PCBA or on the radiator and connected to the PCB through metal wires. In other embodiments, other types of light sources can be selected according to actual needs.

[0049] The same light source module 4 can be matched with different reflector bowl modules 5 or condenser modules 6 to meet different design requirements; the same light source module 4 and reflector bowl module 5 or condenser module 6 can be matched with different shapes and achieve different high and low beam functions and ADB designs.

[0050] The solution of the present utility model will be further described in detail below with specific implementation cases.

[0051] As Figure 1 shown, a high beam module is disclosed. The opening of the high beam module is a reflective design with a size of 5 mm (the opening of the high beam module is not limited to 5 mm and can also be other sizes). Here, it is only an example that it can be applied to the high beam function, and it can also be applied to other functions according to actual needs, such as low beam, ADB, etc. The lens 1 includes 4 optical path channels, the light source module 4 includes 4 groups of light source sub-modules, and the reflector bowl module 5 also includes 4 groups of reflector bowl sub-modules, and each sub-module corresponds to the lens 1 one by one.

[0052] As Figure 2 and Figure 3 shown, the lens 1.1 is matched with the light source module 4.1 and the reflector bowl module 5.1, and the lens 1.2 is matched with the light source module 4.2 and the reflector bowl module 5.2. These two cavities are designed for high beam spot (bright spot). The lens 1.3 is matched with the light source module 4.3 and the reflector bowl module 5.3, and the lens 1.4 is matched with the light source module 4.4 and the reflector bowl module 5.4. These two cavities are designed for high beam base (widening). The light source modules 4.3 and 4.4 use LEDs with different chip sizes to achieve different widening designs. At the same time, the partition design can control the light pattern of each area separately to achieve the best design result. Under the same shape and module parts (lens 1, lens bracket 2 and main radiator 3), replace the local light source module 4 or reflector bowl module 5 to achieve different performances and thus meet different design requirements.

[0053] As Figure 4 and Figure 5As shown, light rays are emitted from the LEDs on the light source modules 4.1 and 4.2, reflected by the corresponding reflector bowl modules 5.1 and 5.2 and converged to the areas of the lenses 1.1 and 1.2, and finally exit to form the high beam spot (bright spot) light pattern. Light rays are emitted from the LEDs on the light source modules 4.3 and 4.4, reflected by the corresponding reflector bowl modules 5.3 and 5.4 and converged to the areas of the lenses 1.3 and 1.4, and finally exit to form the high beam base (broadened) light pattern.

[0054] Design the contact surface between the main radiator 3 and the light source module 4 into an L shape, which can realize the replacement of the laser light source module. For example, Figure 6 As shown, the LED light source module 4.1 and the reflector bowl 5.1 can be directly replaced with the laser light source module 4.5 and the reflector bowl module 5. After replacement, as Figure 7 shown, the light source ends of the two modules share the same main radiator 3, the light source modules 4.2 - 4.4 and the reflector bowl modules 5.2 - 5.4, as well as the same lens 1 and lens bracket 2, to achieve different high beam performances. On the premise of not affecting the uniformity, the replaced laser light source design can meet the requirement of the high beam maximum value above 200 lx.

[0055] The number and positions of the partitions of the lens 1 are as Figure 8 shown. The lenses 1.1 and 1.2 are designed as convex lenses to achieve the light concentrating effect and meet the requirements of the high beam spot (bright spot). The lenses 1.3 and 1.4 are designed as concave lenses to achieve the diffusion effect and meet the requirements of the high beam base (broadened). The concentrating effects of the lenses 1.1 and 1.2 are different, and similarly, the diffusion effects of the lenses 1.3 and 1.4 are also different. Different concentrating and diffusion avoid the bright-dark contrast between the light patterns, so that the requirements of both the high beam maximum value and the uniformity can be taken into account at the same time.

[0056] More specifically, as Figure 9 and Figure 10 the schematic diagrams of the high and low beam optical systems of the reflective module and the direct projection module. For the high beam system, light rays are emitted from the LEDs or lasers on the light source module 4, converged by the corresponding reflector bowl module 5 or condenser module 6 to the corresponding area of the lens 1, and finally exit to form the high beam light pattern. Similarly, for the low beam system, light rays are emitted from the LEDs or lasers on the light source module 4, converged by the corresponding reflector bowl module 5 or condenser module 6 to the corresponding cut-off line baffle 7 and then pass through the corresponding area of the lens 1, and finally exit to form the low beam light pattern. Multiple light source modules 4 are matched with the corresponding reflector bowl modules 5 or condenser modules 6 and are all installed on the main radiator 3 to form the module light source end.

[0057] The present utility model can be configured to generate multiple light distributions, and the types of the multiple light distributions are different. The type of each light distribution is any one of the following: low beam illumination, high beam illumination, adaptive low beam illumination, ADB high beam illumination, corner fog lamp illumination, urban road mode illumination, rural road mode illumination, highway mode illumination, curve mode illumination, rain and fog mode illumination, position signal lamp, turn signal lamp, daytime running lamp, welcome lamp, ambient lamp, etc.

[0058] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0059] The specific embodiments of the present utility model have been described above. It should be understood that the present utility model is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present utility model. Without conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.
