Description

Technical Field

[0001] This invention belongs to the field of vehicle lighting technology, and specifically relates to a signal light optical system and vehicle. Background Technology

[0002] With the continuous development of automotive technology, the design of automotive signal lights is constantly pursuing innovation and aesthetics. Currently, a type of automotive signal light with a dazzling lighting effect has appeared on the market, with its dazzling patterned surface typically designed on the light-emitting surface of the headlight. However, this design has a significant drawback. Because the dazzling patterned surface is located on the light-emitting surface, it interferes with the normal propagation path of light, thus affecting the light distribution performance of the signal light. Specifically, this design causes the light distribution patterns of the turn signals and daytime running lights to deviate from the required centered position of the headlight, thus failing to meet the stringent requirements of relevant regulations for the light distribution performance of automotive signal lights.

[0003] In existing thick-walled light guide structure designs, there is an irreconcilable contradiction between meeting the regulatory requirements for turn signals and daytime running lights and achieving a brilliant lighting effect. On the one hand, regulations have clear and strict provisions on the light distribution performance of automotive signal lights to ensure driving safety and accurate signal transmission; on the other hand, achieving a brilliant lighting effect often requires special design of the light-emitting surface, which inevitably affects the light distribution performance. This contradiction presents engineers with a huge challenge during the design process, often making it difficult to simultaneously meet regulatory requirements and aesthetic needs.

[0004] Therefore, how to solve the above-mentioned technical defects is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The core of this invention is to provide a signal light optical system and vehicle that can simultaneously meet the requirements of both dazzling lighting effects and signal light regulations.

[0050] To enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] For details, please refer to Figures 1-2 The present invention provides a signal light optical system, including a first light source assembly 100, a first thick-walled member 200, a second light source assembly 300, and a second thick-walled member 400.

[0052] The first thick-walled component 200 is provided with a first light-incident surface, a first light-concentrating and reflecting surface 210, and a first light-emitting surface with a first patterned surface 220. The second thick-walled component 400 is provided with a second light-incident surface, a third light-incident surface, a second light-concentrating and reflecting surface 410, a second patterned surface 420, a brilliant patterned surface 430, a second light-emitting surface 440, and a third light-emitting surface 450.

[0053] The first light source assembly 100 is disposed opposite to the first light-incident surface, that is, the light-emitting surface of the first light source assembly 100 faces the first thick-walled member 200. The second light source assembly 300 is disposed opposite to the second light-incident surface, that is, the light-emitting surface of the second light source assembly 300 faces the second thick-walled member 400. The first light-emitting surface, the third light-incident surface, and the second light-emitting surface 440 are disposed opposite to each other in sequence along the light transmission direction.

[0054] It should be noted that both the first light source assembly 100 and the second light source assembly 300 are used to provide initial light. The light source assembly can be an LED lamp. In other embodiments, the light source assembly can also be a halogen lamp or other light-emitting device, which will not be elaborated here. The first light source assembly 100 and the second light source assembly 300 can be soldered onto a circuit board, and the light-emitting surfaces of the first light source assembly 100 and the second light source assembly 300 face their respective corresponding thick-walled components.

[0055] The angle of the first light-concentrating reflective surface 210 is configured to guide light rays from the first light-incident surface to the first light-exiting surface. The angle of the first light-exiting surface is configured to guide light rays horizontally to the third light-incident surface. The angle of the third light-incident surface is configured to guide most of the light rays horizontally to the second light-exiting surface 440 and guide a small portion of the light rays to the brilliance patterned surface 430. The angle of the second light-concentrating reflective surface 410 is configured to guide light rays from the second light-incident surface to the second patterned surface 420. The angle of the second patterned surface 420 is configured to guide light rays from the second light-concentrating reflective surface 410 to the brilliance patterned surface 430. The angle of the brilliance patterned surface 430 is configured to guide light rays to the third light-exiting surface 450.

[0056] After the first light source component 100 is lit, the light emitted from it enters the first thick-walled component 200 through the first light-incident surface, is reflected by the first focusing reflective surface 210 onto the first patterned surface 220, and after total internal reflection, enters through the third light-incident surface of the second thick-walled component 400. Most of the light is horizontally emitted through the second light-out surface 440, meeting the regulatory requirements for light intensity and light pattern. The third light-incident surface can also guide a small portion of the light into the brilliant patterned surface 430, where it is reflected and forms a brilliant lighting effect.

[0057] After the second light source component 300 is lit, the light emitted from it enters the second thick-walled component 400 through the second light-incident surface, is reflected by the second light-concentrating reflective surface 410 onto the second patterned surface 420, and the light exits from the second patterned surface 420 to the brilliant patterned surface 430. After refraction, it exits from the third light-emitting surface 450, forming a brilliant lighting effect.

[0058] This invention provides a signal light optical system. By setting a first patterned surface 220 on the light-emitting surface of a first thick-walled member 200, light emitted from a first light source assembly 100 is reflected by a first focusing reflective surface 210 onto the first patterned surface 220, and then emitted from the first patterned surface 220 onto a third light-incident surface. The third light-incident surface can guide most of the light to exit horizontally through a second thick-walled member 400, meeting regulatory requirements for light intensity and light pattern, while also satisfying customer uniformity requirements. The third light-incident surface can also guide a small portion of the light to enter the brilliance patterned surface 430, where it is reflected and forms a brilliance lighting effect. Meanwhile, a second patterned surface 420 and a brilliant patterned surface 430 are provided on the second thick-walled component 400. The light emitted by the second light source component 300 is reflected by the second light-concentrating reflective surface 410 onto the second patterned surface 420. The second patterned surface 420 then guides the light onto the brilliant patterned surface 430, and the light is emitted through the second thick-walled component 400, so that the emitted light of the second thick-walled component 400 presents a brilliant lighting effect.

[0059] The above design produces signal light patterns that meet the standards for daytime running lights, position lights, and turn signals without changing the light-emitting and light-receiving surfaces of the optical system, ensuring the overall luminous efficiency of the optical system and simultaneously meeting the requirements of signal light regulations.

[0060] In a specific embodiment, the first light-incident surface is located at the bottom of the first thick-walled member 200, and the first light source assembly 100, the second light source assembly 300, the second light-incident surface, and the second focusing and reflecting surface 410 are all located below the bottom of the first thick-walled member 200. By arranging two light source assemblies adjacent to each other, more functions can be achieved within the limited space of the vehicle headlight by arranging multiple light source assemblies adjacent to each other, while reducing the overall space occupied by the light source assemblies and the circuit board.

[0061] Furthermore, such as Figures 3-5 As shown, in order to improve the space utilization of the two thick-walled components, the second thick-walled component 400 is Z-shaped. The upper horizontal side of the second thick-walled component 400 is provided with a third light-incident surface and a second light-exiting surface 440, respectively. The upper bottom of the second thick-walled component 400 is provided with a brilliant patterned surface 430, and the upper top is provided with a third light-exiting surface 450. The middle transition section of the second thick-walled component 400 is provided with a second patterned surface 420. The lower top of the second thick-walled component 400 is provided with a second light-incident surface, and the lower bottom is provided with a second light-concentrating reflective surface 410.

[0062] The design incorporates a shimmering patterned surface 430 on the lower surface of the signal light optical system, achieving a diamond-like brilliance both under natural light and when illuminated.

[0063] In a further specific embodiment, by utilizing the above arrangement, the first light source assembly 100 and the second light source assembly 300 can be respectively disposed on the front and back surfaces of the same double-sided circuit board 500. This design takes advantage of the characteristics of a double-sided circuit board, allowing different light source assemblies to be disposed on the front and back surfaces, effectively utilizing space and reducing the volume occupied by the circuit board while achieving different lighting functions. Specifically, the first light source assembly 100 and the second light source assembly 300 can be soldered to the double-sided circuit board 500.

[0064] Furthermore, to facilitate demolding, the second thick-walled part 400 has a 5°-20° tilt angle on one side with the second patterned surface 420. This tilt angle reduces friction between the mold and the plastic part, aiding demolding. Simultaneously, it improves the reflection and refraction of light on the surface of the second thick-walled part 400, resulting in a more uniform and aesthetically pleasing optical pattern. This is particularly important for automotive lighting components, where uniform light distribution and excellent optical performance are crucial.

[0065] The second focusing reflector 410 can be adaptively designed according to actual needs, specifically, such as... Figures 3-5As shown, the second focusing reflective surface 410 includes a conical surface 411 and an annular wall surface 412. The tip of the conical surface 411 faces the second light-incident surface, and the annular wall surface 412 is disposed on the side of the conical surface 411 away from the second patterned surface 420. Part of the light from the second light-incident surface is reflected by one side of the conical surface 411 onto the second patterned surface 420, and another part of the light is reflected by the other side of the conical surface 411 onto the annular wall surface 412, and then reflected again to reach the second patterned surface 420. See details... Figure 9 and Figure 10 .

[0066] Of course, the second light-concentrating reflective surface 410 can also be an ellipsoid, a parabola, or other specially designed curved surface, as long as it can achieve total internal reflection of light on the curved surface where the second light-concentrating reflective surface 410 is located, and direct the reflected light towards the light-emitting surface (second patterned surface 420) of the second thick-walled component 400.

[0067] In a specific embodiment, the first focusing reflective surface 210 includes a plurality of reflective surface units arranged in a horizontal direction, and the first light source assembly 100 includes a plurality of light sources, with each reflective surface unit corresponding to a light source.

[0068] Correspondingly, such as Figure 11 As shown, the second focusing reflective surface 410 includes a plurality of reflective surface units arranged in a horizontal direction, and the second light source assembly 300 includes a plurality of light sources, with each reflective surface unit corresponding to one light source.

[0069] The aforementioned set of light sources and reflective surface units can be combined to form a light incident unit. There are multiple sets of light sources and reflective surface units in a one-to-one correspondence, and these multiple sets of light incident units are arranged sequentially. Multiple sets of light sources can be located on the same circuit board, or they can be located on different circuit boards according to other needs.

[0070] In a specific embodiment, the first light-incident surface is a plane, a cylinder, or a sphere. The first light-concentrating reflective surface 210 is a concave curved surface. This concave curved surface can be an ellipsoid, a parabola, or other specially designed curved surface. Depending on the different forms of the first light-incident surface, the reflective surface can also take many forms. As long as the light can undergo total internal reflection on the curved surface and the reflected light is directed towards the first light-emitting surface of the first thick-walled member 200, any shape of the first light-concentrating reflective surface 210 that meets the above conditions is within the scope of protection of this application.

[0071] The first patterned surface 220 consists of multiple continuously arranged convex surfaces. These convex surfaces can be a corn kernel pattern or outwardly convex arc surfaces to produce signal light patterns that conform to the standards for daytime running lights, position lights, and turn signals.

[0072] The second light-incident surface can be a plane, cylinder, or sphere. The second light-incident surface and the second focusing and reflecting surface 410 on the light source side of the second thick-walled member 400 can also be varied, such as cylindrical or other curved shapes. The third light-incident surface can be a smooth plane or multiple continuously arranged convex surfaces, and the multiple convex surfaces can be in the form of a corn kernel pattern.

[0073] like Figure 6 As shown, the second patterned surface 420 consists of multiple continuously arranged convex surfaces. These multiple convex surfaces can be corn kernel patterns, or diffused patterns composed of regularly arranged stripes, rectangles, or hexagons. Alternatively, they can be smooth outer convex surfaces without diffused patterns, capable of guiding light refraction and directing it toward the brilliant patterned surface 430 at the bottom of the second thick-walled component 400.

[0074] The second light-emitting surface 440 is a smooth flat surface or multiple continuously arranged convex surfaces, capable of producing signal light patterns conforming to daytime running lights, position lights, and turn signals. The third light-emitting surface 450 is a smooth flat surface or multiple continuously arranged convex surfaces. The diamond-patterned surface 430 is detailed in [link to details]. Figure 7 and Figure 8 .

[0075] The upper and lower surfaces of the second thick-walled component 400 can be varied, such as smooth flat surfaces, diamond-patterned surfaces, or other irregularly shaped reflective surfaces, which can be adapted to the actual optical effect requirements.

[0076] In order to prevent the high heat generated during the operation of the first light source assembly 100 from damaging the optical components, the light-emitting surface of the first light source assembly 100 and the first light-incident surface of the first thick-walled member 200 have a first preset distance, which can be 1mm-2mm.

[0077] Similarly, in order to prevent the high heat generated during the operation of the second light source assembly 300 from damaging the optical components, the light-emitting surface of the second light source assembly 300 and the second light-incident surface of the second thick-walled member 400 have a second preset distance, which can be 1mm-2mm.

[0078] Furthermore, the present invention also provides a vehicle including a signal light optical system as described in the specific embodiments above. The signal light optical system can be applied to vehicles, and of course, it can also be applied to environments such as ship windows, aircraft windows, or curtain walls. This signal light optical system can be a signal light located at the front, rear, or side of the vehicle.

[0079] Obviously, vehicles incorporating the aforementioned signal light optical system have the same beneficial effects, which will not be elaborated upon here.
