Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to an integrated low beam and high luminous intensity ADB module. Background Technology

[0002] As the automotive industry accelerates its evolution towards intelligence and connectivity, driving safety at night and in complex lighting conditions has become a core pain point of concern for the industry.

[0003] A Chinese utility model patent, publication number CN210568133U, entitled "An LED Dual-Beam Module," includes a dual-beam module. Within the module, a lens, an inner lampshade, an LED circuit board one, and a heat sink are sequentially mounted along an axial direction. The inner lampshade has several light guide pillars, each with stripes on both sides. An LED circuit board two is also located above the heat sink. The LED circuit board one and LED circuit board two are angled together. A reflector is also located above the LED circuit board two. The reflector design enables low beam functionality. Simultaneously, the use of a silicone inner lampshade fulfills the requirements for high beam ADB functionality.

[0004] However, this high beam pattern still cannot simultaneously ensure both illumination range and oncoming safety. To address this issue, the applicant proposes an integrated low beam and high luminous intensity ADB module. Utility Model Content

[0005] The purpose of this invention is to provide an integrated low beam and high luminous intensity ADB module to solve the above-mentioned technical problems.

[0006] This utility model provides the following technical solution:

[0007] An integrated low beam and high luminous intensity ADB module includes: a high beam module, a first inner lens, and an outer lens arranged sequentially along the light transmission direction;

[0008] The module also includes a low beam module and a second inner lens disposed directly above the low beam module, with a light-blocking plate disposed in the opposite direction of the light reflected from the second inner lens;

[0009] The high beam module and the low beam module are respectively equipped with high beam LED and low beam LED, and the upper and lower ends of the first inner lens are respectively equipped with an upper surface and a lower surface.

[0010] The light emitted by the high beam LED enters through the light-inlet surface of the first inner lens, is collected when reflected along the upper surface, and is focused when reflected along the lower surface to form a high-intensity high beam pattern.

[0011] Furthermore, the first inner lens is made of silicone.

[0012] Furthermore, the cross-sectional profile of the upper surface is an elliptical parabola, and the cross-sectional profile of the lower surface is a hyperbola.

[0013] Furthermore, the module also includes a lens bracket, and the outer lens is fixedly mounted on the inner side of the lens bracket.

[0014] Furthermore, the module also includes a heat sink, with mounting grooves formed by protrusions on both sides of the heat sink. The high beam module and the first inner lens are both fixedly mounted in the mounting grooves, and a pressing member for fixing is also provided in front of the first inner lens.

[0015] Furthermore, the low beam module, the second inner lens, and the light-blocking plate are all fixedly mounted on the upper outer surface of the heat sink.

[0016] Furthermore, the surfaces of both the low beam module and the high beam module that are attached to the heat sink are copper substrates.

[0017] Furthermore, the number of high-beam LEDs is 13 groups.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by providing a first inner lens, the first inner lens has an upper surface and a lower surface. The cross-sectional profile of the upper surface is an elliptical parabola, and the cross-sectional profile of the lower surface is a hyperbola. Light can be collected as much as possible on the upper surface and focused on the lower surface to form a high-intensity illumination area. Furthermore, by turning off the high beam LED group, illumination of a specific area can be achieved, while reducing the light intensity for oncoming vehicles or pedestrians, thus taking into account both the illumination range and oncoming driving safety.

[0020] 2. In this utility model, by integrating the low beam and high beam, the number of components and installation complexity of the vehicle lighting system are reduced, saving interior space. At the same time, the combination of components can also achieve the purpose of cost reduction and efficiency improvement. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: an integrated low beam and high luminous intensity ADB module, including a high beam module 2, a first inner lens 5 and an outer lens 41 arranged sequentially along the light transmission direction. The module also includes a low beam module 1 and a second inner lens 8 disposed directly above the low beam module 1. The high beam module 2 and the low beam module 1 are respectively equipped with a high beam LED 21 and a low beam LED 11. The light emitted from the different LEDs is reflected by the corresponding inner lens to the outer lens 41 to form the low beam and high beam.

[0031] like Figure 1 As shown, a light-blocking plate 7 is provided along the direction of reflected light from the second inner lens 8. In the low beam mode, the light emitted by the low beam LED reaches the second inner lens 8. After total internal reflection by the second inner lens 8, part of the light is directly emitted from the outer lens 41, and the other part of the light is reflected by the light-blocking plate 7 and then emitted from the outer lens 41. The two parts of the light together form the basic low beam pattern.

[0032] In high beam mode, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the light emitted by the high beam LED 21 enters the first inner lens 5, is reflected by the first inner lens 5, and is then emitted along the outer lens 41 to form the high beam pattern. Figures 6-7As shown, the first inner lens 5 includes an upper surface 51 and a lower surface 52. Further, the cross-sectional profile of the upper surface 51 is an elliptic paraboloid, and the cross-sectional profile of the lower surface 52 is a hyperboloid. When light passes through the upper surface 51, due to its elliptic paraboloid characteristics, all light rays parallel to the optical axis converge at the focal point after reflection by the paraboloid. Therefore, the light rays passing through the upper surface 51 are collected as much as possible and follow the following... Figure 7 The light is reflected at the angle shown so that it propagates toward the area that needs to be illuminated, avoiding scattering of light in ineffective directions. By adjusting the curvature and shape of the upper surface, the angle of the reflected light can be adjusted to guide the light toward a specific area.

[0033] Light rays passing through the lower surface 52 can be focused. Due to the properties of the hyperboloid, as light passes through the lower surface 52, it will be converged (convex surface) or diffused (concave surface) depending on the curvature of the surface. When it is necessary to enhance the illumination intensity of a specific area (such as the center of a road), the surface is designed to be convex, so that light rays are focused there, thereby increasing the illumination intensity of that area (e.g., Figure 6 As shown, for areas that do not require strong light, the light can be diffused to reduce the light intensity, thus enabling the ADB module to distribute light intensity differently in different areas. The cooperation between the upper surface 51 and the lower surface 52 can achieve precise division of light intensity areas for the high beam system.

[0034] Further explanation is needed on how to achieve differentiated light intensity distribution in different regions, such as... Figure 3 As shown, the high beam LED 21 has 13 groups. By turning different groups of high beam LED 21 on and off, the light intensity in different areas can be adjusted. When the weather is unclear or the road conditions are at night, the lights in the area where oncoming vehicles or pedestrians are located can be dimmed or turned off, while maintaining good lighting in other areas, making it easier for the driver to observe the road conditions ahead.

[0035] Furthermore, the first inner lens 5 is made of silicone.

[0036] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the module also includes a lens bracket 4, wherein an outer lens 41 is mounted on the inner side of the lens bracket 4, and the front end of the outer lens 41 protrudes from the outside of the lens bracket 4.

[0037] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, the module also includes a heat sink 3. The heat sink 3 has mounting grooves 31 formed by protrusions on both sides. The high beam module 2 and the first inner lens 5 are fixedly installed in the mounting grooves 31. A pressing member 6 for fixing is also provided in front of the first inner lens 5 to press the first inner lens 5 into the mounting grooves 31. The low beam module 1, the second inner lens 8 and the light blocking plate 7 are all fixedly installed on the upper outer surface of the heat sink 3.

[0038] Furthermore, both the low beam module 1 and the high beam module 2 are attached to the heat sink 3 with copper substrates, which can conduct heat to the heat sink 3 to achieve heat dissipation.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
