Description

Technical Field

[0001] This invention relates to the fields of optical system design and automotive lighting technology, and more specifically, to a concentrator structure and a thick-walled automotive lamp. Background Technology

[0002] With the rapid development of the automotive industry and the intensification of market competition, major automakers are not only pursuing improved product performance, but also constantly seeking a balance between cost optimization and aesthetic design.

[0003] As a crucial component of a car's exterior, headlights are not only a key guarantee for driving safety but also a core element of vehicle aesthetic design. However, traditional thick-walled focusing structures suffer from inefficiencies, energy waste, and uneven illumination, especially in scenarios with shared functions (such as turn signals and position lights illuminating the same area). While traditional high-cost bi-LED solutions can improve lighting effects and uniformity to some extent, they still have significant shortcomings in terms of cost control and design flexibility.

[0004] Currently, in the field of automotive lighting, condensers are widely used in the design of car lights as an important optical element.

[0005] Traditional concentrator structures are typically designed with a single focal point for precise focusing of a single light source. However, when multiple light sources need to be reused, traditional designs are prone to defocusing, causing the light source to deviate from the optimal focusing position. This results in the concentrator not being able to reach its maximum efficiency. Defocusing leads to beam divergence, energy waste, increased system energy consumption, and may cause the internal temperature of the headlight to rise, accelerating the aging of semiconductor materials and reducing luminous efficiency and the lifespan of the light source. At the same time, the inability of multiple light sources to achieve ideal focusing simultaneously can also create uneven brightness on the light-emitting surface, affecting the lighting effect and user experience. To address these issues, we propose a concentrator structure and a thick-walled headlight. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concentrator structure and a thick wall for vehicle lamps to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a concentrator structure and a thick wall for a vehicle lamp, comprising a thick wall for the vehicle lamp and a concentrator assembly, wherein the concentrator assembly is installed within the thick wall for the vehicle lamp. A protruding plate is provided on one side of the light-concentrating component, and two slots are formed on one side of the light-concentrating component through the installation of the protruding plate. LED light source one and LED light source two are respectively provided on one side of the light-concentrating component. Refractive surface one and refractive surface two are respectively provided on the top and bottom of the light-concentrating component. Total reflection surface one, light incident surface one, light incident surface two and total reflection surface two are respectively provided on the inner side of the light-concentrating component. The thick wall of the headlight is provided with a light source three, and on one side of the light source three are respectively provided a refractive surface three, a reflective surface three, an incident light surface three, a total reflection surface three, and a light emitting surface.

[0008] Preferably, the first refracting surface, the second refracting surface, the first incident surface, and the second incident surface are all provided with optical patterns to make the collimated and concentrated light beam propagate more uniformly and optimize the light output effect.

[0009] Preferably, the width of the convex plate is 0.6mm to 3mm, and columnar optical textures are arranged on both sides to reduce beam transmission.

[0010] Preferably, part of the light beam from the LED light source is refracted for the first time through the incident surface to generate a parallel beam; the other part of the light beam is deflected through the refraction surface and then directed towards the total reflection surface, where total reflection is achieved and finally a parallel beam is generated for output.

[0011] Preferably, part of the beam from the second LED light source undergoes initial refraction through the second incident surface to generate a parallel beam; the other part of the beam is deflected through the second refraction surface and then strikes the second total reflection surface, where total reflection is achieved and a parallel beam is finally generated for output.

[0012] Preferably, the light source three, and its corresponding refractive surface three, reflective surface three, incident surface three, and total internal reflection surface three, ultimately output the light beam through the emitting surface to achieve more complex optical effects.

[0013] Preferably, the thick wall of the headlight is provided with a double-layer thick wall structure consisting of a thick wall layer one and a thick wall layer two.

[0014] Preferably, a stepped optical pattern is added between the first thick-walled layer and the second thick-walled layer.

[0015] The technical effects and advantages of this invention are as follows: When in use, this invention employs a multi-focus optimization strategy, successfully solving the "defocusing" phenomenon that easily occurs in traditional concentrators within a shared area of ​​multiple light sources. This innovative design allows the optical center of each LED light source to be precisely placed at the focal point of its respective concentrator element, thereby achieving efficient control of multiple light sources within the same concentrator structure. The concentrator structure of this invention can significantly improve the brightness of the screen center while optimizing the uniformity of illumination and reducing light spots and uneven brightness.

[0016] In use, the convex plate integrated between the two focusing elements effectively reduces light transmission and interference between different light sources, ensuring the independence and precision of the optical path of each light source. This design not only improves the stability and reliability of the lighting system, but also significantly reduces material costs and design complexity by using two single-beam LEDs instead of the traditional high-cost dual-beam LED solution. At the same time, the width of the convex plate is designed to be 0.6mm~3mm, and columnar optical textures are configured on both sides to further reduce the direct propagation of light and optimize the overall optical path design. These improvements collectively enhance the flexibility and market competitiveness of vehicle lighting design. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As attached Figures 1-8 The illustrated concentrator structure and headlight thick wall include a headlight thick wall 61 and a concentrator assembly 301, wherein the concentrator assembly 301 is installed within the headlight thick wall 61. A protruding plate 3 is provided on one side of the light-concentrating component 301. Two slots are formed on one side of the light-concentrating component 301 through the installation of the protruding plate 3. An LED light source 1 and an LED light source 2 are respectively provided on one side of the light-concentrating component 301. A refractive surface 4 and a refractive surface 9 are respectively provided on the top and bottom of the light-concentrating component 301. A total reflection surface 5, an incident light surface 6, an incident light surface 7, and a total reflection surface 8 are respectively provided on the inner side of the light-concentrating component 301. A light source 601 is provided on one side of the thick wall 61 of the headlight. A refractive surface 602, a reflective surface 603, an incident light surface 604, a total reflection surface 605, and a light-emitting surface 607 are respectively provided on one side of the light source 601. Refraction surface 1 (4), refraction surface 2 (9), incident surface 1 (6), and incident surface 2 (7) are all provided with optical patterns to make the collimated and focused beam propagate more uniformly and optimize the light output effect; the width of the convex plate 3 is 0.6mm~3mm, and columnar optical patterns are arranged on both sides to reduce beam transmission; part of the beam from LED light source 1 is refracted for the first time through incident surface 1 (6) to generate a parallel beam; another part of the beam is deflected through refraction surface 1 (4) and then directed towards the total internal reflection surface 1 (5), where total internal reflection is achieved and finally a parallel beam is generated for output; part of the beam from LED light source 2 is refracted through incident surface 2 (7) to... The first refraction generates a parallel beam; another part of the beam is deflected by the second refraction surface 9, and then shines on the second total reflection surface 8, where total reflection is achieved, and finally a parallel beam is generated for output; the third light source 601, and its corresponding third refraction surface 602, third reflection surface 603, third incident surface 604 and third total reflection surface 605, finally output the beam through the light emitting surface 607 to achieve a more complex optical effect; it also includes: the thick wall 61 of the headlight is provided with a double thick wall structure of thick wall layer 1 611 and thick wall layer 2 612, and a stepped optical pattern is added between thick wall layer 1 611 and thick wall layer 2 612; The convex plate 3, integrated between two independent focusing elements, serves to reduce or prevent light transmission and interference between different LED light sources, ensuring the independence and precision of the optical path for each light source. The width of the convex plate 3 is designed to be 0.6mm to 3mm, an optimized range that effectively blocks direct light transmission without significantly obstructing the overall optical path. Columnar optical patterns are arranged on both sides of the convex plate 3. These patterns further reduce direct light propagation through scattering and refraction, thereby reducing optical path interference between different light sources. Optical patterns on the incident light surface 6, incident light surface 7, and refractive surfaces 4 and 9 are primarily used to optimize the light output effect, making the collimated and focused beam propagate more uniformly. These optical patterns, through specific geometric shapes and arrangements, perform minute scattering and refraction adjustments on the incident light. This adjustment helps eliminate light spots and uneven brightness, improving the overall uniformity and quality of the output light.

[0028] The luminous surface 607, with its polygonal optical pattern, is located at the final output end of the concentrator structure. Its main function is to further diffuse and adjust the light beam after reflection by the total internal reflection surface to meet specific lighting needs and regulatory requirements. The polygonal optical pattern, through its unique geometry, scatters and refracts the incident light in multiple directions. This scattering effect helps to expand the beam's illumination range while maintaining its uniformity and consistency. In automotive lighting design, the polygonal optical pattern luminous surface is particularly suitable for scenarios requiring broad illumination or specific light pattern requirements, such as turn signals and daytime running lights. The total internal reflection surface 605 forms a specific angle (e.g., 45°) with the incident ray. This specific angle (e.g., 45°) is precisely calculated. This angle ensures that the light is completely reflected on the total internal reflection surface and that the reflected beam propagates in a predetermined direction. When the incident ray is incident on the total internal reflection surface 605 at a specific angle (e.g., 45°), according to the law of refraction, the light will be completely reflected and propagate in a direction symmetrical to the incident ray. This process ensures that the energy loss of the light is minimized, while improving the collimation and directionality of the beam. The headlight thick wall 61 is provided with a double thick wall structure consisting of a first thick wall layer 611 and a second thick wall layer 612. A stepped optical pattern is added between the first thick wall layer 611 and the second thick wall layer 612, which helps to further optimize the propagation and light output effect of the light.

[0029] The working principle of this invention is as follows: During the emission and initial refraction of the light source, LED light source 1 emits a light beam, part of which is directly refracted by the incident surface 6. Due to the specific design of the incident surface, this part of the light beam is converted into a parallel beam that propagates forward. At the same time, another part of the light beam is deflected by the refraction surface 4, changing its initial propagation direction. Similarly, LED light source 2 also emits a light beam according to the same principle, undergoing initial refraction and path deflection by the incident surface 7 and the refraction surface 9, respectively. During total internal reflection and beam collimation, the beam, after being deflected by the refractive surface 4, continues to propagate to the total internal reflection surface 5. At this interface, according to the law of refraction, the beam undergoes total internal reflection and is further collimated into a parallel beam with consistent height. The beam of the LED light source 2 also undergoes a similar process, undergoing total internal reflection on the total internal reflection surface 8 to achieve beam collimation. This invention employs a multi-focus optimization strategy to ensure that the optical center of each LED light source is precisely placed at the focal point of its respective focusing element. This design enables efficient control of multiple light sources within the same focusing structure, avoiding the "defocusing" phenomenon that easily occurs in traditional focusing elements within a shared area of ​​multiple light sources. The anti-light-crossing protrusion 3 integrated between the two focusing elements effectively reduces the transmission and interference of light between different light sources, ensuring the independence and accuracy of the optical path of each light source. The optical patterns on the incident surface 6, incident surface 7, refractive surface 4, and refractive surface 9 contribute to the uniformity of the collimated and focused light beam during propagation. These patterns optimize the light output through scattering and refraction, reducing light spots and uneven brightness. When light source 601 is used, its emitted light beam is collimated by incident surface 604 and guided to total internal reflection surface 605. Refractive surface 602 and reflective surface 603 work together to further collimate the light and guide it to total internal reflection surface 605. Total internal reflection surface 605 forms a specific angle (e.g., 45°) with the incident light beam, guiding the beam to the final emitting surface 607 after total internal reflection. The polygonal optical patterns on emitting surface 607 effectively diffuse the beam distribution, meeting relevant regulatory requirements and achieving more complex optical effects. Compared to traditional focusing systems that use dual light sources, the beam achieved by this invention through a multi-focus optimization strategy exhibits significant advantages in both collimation and energy utilization efficiency.
