Description

Technical Field

[0001] This utility model relates to the field of lens technology, specifically to an ultra-thin high and low beam lens module. Background Technology

[0002] With the development of the automotive industry, consumers have increasingly stringent requirements for the spatial layout flexibility and optical performance of automotive headlights. Traditional high and low beam lens modules have two major shortcomings: First, their large structural thickness occupies too much space on the front of the car, limiting the freedom of vehicle styling design and hindering overall vehicle weight reduction; second, their poor optical performance results in either insufficient center illumination or poor light uniformity, affecting nighttime driving safety and comfort. Moreover, traditional reflectors have a single focal point, resulting in a relatively small light reflection angle, and the lens uses a single-curved surface design, making it difficult to ensure both center brightness and good beam width.

[0003] To address this, we offer an ultra-thin high and low beam lens module. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-thin high and low beam lens module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-thin high and low beam lens module, including a housing, a light source assembly disposed inside the housing, an aspherical reflector disposed inside the housing, a hyperboloid fusion lens disposed on the housing, and a heat dissipation assembly disposed on the back of the housing, the heat dissipation assembly being fixedly connected to the housing by bolts.

[0006] Optionally, the housing has an ultra-thin structure, and the aspherical reflector is arranged with a gradually changing focal point along the horizontal and vertical directions. The aspherical reflector is used to reflect the light emitted by the light source assembly.

[0007] Optionally, the hyperboloid fusion lens includes a convex surface and a concave surface. The convex surface is used to compress the peripheral light emission angle to meet the central illuminance requirement, and the concave surface is used to expand the central light angle to improve light uniformity.

[0008] Optionally, the light source assembly consists of multiple LED beads arranged in a matrix in the light source mounting area within the housing.

[0009] Optionally, the heat dissipation component includes heat dissipation fins for dissipating heat from the light source component.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The ultra-thin structure design of the housing of this utility model greatly saves the installation space of the car headlight, adapts to the styling design needs of more car models, and improves applicability. The synergistic design of the aspherical reflector and the hyperboloid fusion lens not only ensures sufficient central illuminance in the illumination area, but also improves the uniformity of light, effectively improving the night driving vision and improving practicality. It solves the problem of wide horizontal and narrow vertical light distribution of high and low beams, improves optical efficiency, and completes the entire process of beam splitting, directional deflection, cutoff line generation and beam diffusion within a thickness of 18mm, achieving a small size and high light efficiency lighting effect.

[0012] 2. By setting heat dissipation fins, this utility model can quickly dissipate the working heat of the light source component, ensuring the long-term stable operation of the module and achieving a heat dissipation effect. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5The ultra-thin high and low beam lens module includes a housing 1, which has an ultra-thin structure. The housing 1 serves as the module integration carrier, enabling coaxial positioning and installation of the light source component 2, reflector, and lens, forming a closed optical cavity to avoid stray light interference. The ultra-thin design of the housing 1 significantly saves installation space for automotive headlights, adapting to the styling requirements of more vehicle models and improving applicability. The housing 1 houses the light source component 2, which consists of multiple LED beads arranged in a matrix within the light source mounting area of ​​the housing 1. The light source component 2 provides brightness, and the arrangement of the LED beads achieves initial light homogenization. The housing 1 also houses an aspherical reflector 3, whose focal point gradually changes along the horizontal and vertical directions. The aspherical reflector 3 reflects the light emitted by the light source component 2 and directs the divergent light from the LED light source. The reflector compresses the beam divergence angle. A hyperboloid fusion lens 4 is provided on the housing 1. The hyperboloid fusion lens 4 includes a convex surface and a concave surface. The convex surface is used to compress the peripheral light emission angle to meet the central illuminance requirements, and the concave surface is used to expand the central light angle to improve the light uniformity. The hyperboloid fusion lens 4 performs secondary shaping on the beam output by the reflector to optimize the optical indicators of high and low beam illumination. The synergistic design of the aspherical reflector 3 and the hyperboloid fusion lens 4 not only ensures sufficient central illuminance in the illumination area, but also improves the light uniformity, effectively improving the visibility of vehicles at night. A heat dissipation component 5 is provided on the back of the housing 1. The heat dissipation component 5 is fixedly connected to the housing 1 by bolts. The heat dissipation component 5 includes heat dissipation fins 51, which are used to dissipate heat from the light source component 2. The heat dissipation fins 51 conduct heat out of the light source component 2 and dissipate the conducted heat through external air convection.
