[0024] In related technologies, automotive lighting modules generally have relatively limited functions, typically focusing solely on nighttime illumination. During daytime driving, dedicated daytime running lights are needed to emit light of a specific shape and brightness to ensure driving safety. However, effective integration of lighting modules with daytime running lights is difficult, usually requiring a separate daytime running light structure within the overall lighting assembly. This not only increases the overall size and weight of the lighting assembly, making the lighting design less compact and aesthetically pleasing, thus affecting the overall appearance of the vehicle, but also increases manufacturing costs and assembly complexity.

[0025] The following is for reference. Figure 1 - Figure 7 A lighting module 1 for a vehicle lighting assembly is described according to an embodiment of the present invention.

[0026] like Figures 1-4 As shown, the lighting module 1 for vehicle lighting components according to the present invention includes an inner lens 11, an outer lens 12 and a daytime light component 13, which can realize both nighttime lighting functions, such as low beam lighting, and daytime lighting functions.

[0027] The inner lens 11 is provided with a first light guide 111 and a second light guide 112. The end of the first light guide 111 has a light-inlet surface 1111, and the second light guide 112 is located at the front end of the first light guide 111, with a light-outlet surface 1121 on the second light guide 112. When light emitted from the light source 14 (such as an LED in a car headlight) shines on the light-inlet surface 1111, the light can smoothly enter the interior of the first light guide 111. The first light guide 111 conducts the incoming light, changing the direction of light propagation through its own optical properties, allowing the light to travel along a predetermined path within it. After being conducted by the first light guide 111, the light enters the second light guide 112 to continue propagating. Further guidance and processing of the light result in it being emitted from the light-outlet surface 1121 on the second light guide 112.

[0028] The outer lens 12 is located at the front end of the second light guide 112. That is, after the light is emitted from the light-emitting surface 1121 of the inner lens 11, it enters the outer lens 12. The outer lens 12 can further process the light emitted from the inner lens 11 through its own optical properties, improve the distribution and uniformity of the light, so that the light emission effect of the vehicle lamp meets the design requirements and realizes the night lighting function.

[0029] The daytime light component 13 is located at the bottom of the second light guide 112 and is at least partially opposite to the first light guide 111 in the front-rear direction. It utilizes the space inside the headlight component, avoids occupying too much extra space, and makes the structure of the entire lighting module 1 more compact, which is conducive to the miniaturization and lightweight design of the headlight.

[0030] The daytime lighting assembly 13 is located behind the outer lens 12 and is adapted to emit light through the outer lens 12. When driving during the day, the nighttime lighting function is turned off, and the light emitted by the daytime lighting assembly 13 can be emitted through the outer lens 12 and exit the headlight assembly to achieve the daytime lighting function.

[0031] Both the light source for nighttime illumination and the light source for daytime illumination are emitted through the outer lens 12, thus integrating nighttime and daytime illumination functions into a single lighting module 1. Furthermore, by arranging the inner lens 11 and the daytime light assembly 13 in a compact and reasonable manner, the internal space of the vehicle headlight assembly is fully utilized, making the entire lighting module 1 structurally compact and effectively contributing to the miniaturization and lightweight design of the vehicle headlight.

[0032] According to the lighting module 1 of the present invention, the first light guide 111 of the inner lens 11 receives the light emitted by the light source 14 through the light-inlet surface 1111 and changes the propagation direction according to its own optical characteristics, and conducts it along a predetermined path. After being further guided and processed by the second light guide 112, it is emitted from the light-outlet surface 1121 to realize the night lighting function (such as low beam lighting). The outer lens 12 optimizes the distribution and uniformity of the light emitted by the inner lens 11 to achieve the designed light output effect. The daytime light component 13 is located at the bottom of the second light guide 112 and is directly opposite to the first light guide 111. The internal space is used to make the structure compact, which is conducive to the miniaturization and weight reduction of the vehicle lamp. It is located behind the outer lens 12 and emits light through the outer lens 12. It realizes daytime lighting when the night lighting is turned off during daytime driving, thus improving the overall lighting function and performance of the vehicle lamp.

[0033] Therefore, the lighting module 1 according to the present invention achieves nighttime and daytime lighting functions in a compact and integrated manner, which is beneficial to the small and lightweight design of vehicle lights.

[0034] According to some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the daytime light assembly 13 includes a light guide 131 and a light-emitting element 132. The light guide 131 is used to conduct and distribute light, while the light-emitting element 132 is used to generate light. The two work together to achieve the function of daytime illumination.

[0035] The light guide 131 is disposed at the bottom of the second light guide 112, utilizing the space inside the vehicle lamp assembly. The second light guide 112 itself is used for light conduction and emission in the night lighting system of the vehicle lamp. By placing the light guide 131 at its bottom, the daytime light assembly 13 is spatially integrated with the night lighting system, avoiding additional space occupation and contributing to the miniaturization and compact design of the overall vehicle lamp.

[0036] The light guide 131 is located behind the outer lens 12, so that the light transmitted from the light guide 131 can smoothly enter the outer lens 12. The light is then further processed and optimized by the optical characteristics of the outer lens 12, and finally the daytime lighting effect that meets the design requirements is achieved.

[0037] The light guide 131 extends in the width direction of the second light guide 112, which allows the light guide 131 to better cooperate with the second light guide 112. At the same time, the length of the light guide 131 can be reasonably designed according to the width of the vehicle headlight, so as to ensure that the light can be uniformly transmitted within the light guide 131 and can cover a suitable range when emitting light, thus meeting the requirements of brightness uniformity and coverage of daytime lighting.

[0038] The light-emitting element 132 is disposed at one end of the light guide element 131 and is adapted to emit light toward the light guide element 131, so that the light emitted by the light-emitting element 132 can directly enter the light guide element 131, reducing light loss and scattering during propagation. The light-emitting element 132 emits light toward the light guide element 131, ensuring that the light can enter the interior of the light guide element 131 efficiently. Then, through the conduction and distribution of the light guide element 131, the light is transmitted to various parts of the light guide element 131, ultimately achieving a uniform daytime lighting effect.

[0039] When the daytime lighting function needs to be activated, the light-emitting element 132 starts working and emits light. Since the light-emitting element 132 emits light towards the light guide element 131, the light can directly enter the interior of the light guide element 131. The light guide element 131 utilizes its own optical properties, such as the principle of total internal reflection, to conduct and distribute the light within itself. During the conduction process, the light gradually diffuses and becomes evenly distributed, eventually exiting from the surface of the light guide element 131. After entering the outer lens 12, the emitted light undergoes optical processing, further improving the distribution and uniformity of the light, allowing the light to exit the vehicle lamp assembly with the light pattern and brightness required by the design, thus achieving the daytime lighting function.

[0040] By setting the light guide 131 at the bottom of the second light guide 112 and behind the outer lens 12, and by rationally designing the extension direction of the light guide 131 and the position of the light-emitting element 132, the internal space of the vehicle lamp assembly is fully utilized, which helps to achieve the miniaturization and lightweight design of the vehicle lamp.

[0041] According to some embodiments of this utility model, such as Figures 1-5 As shown, the light guide 131 has an arcuate surface 1311 that protrudes towards the front. Therefore, the front surface of the light guide 131 is arcuate, protruding towards the front of the headlight (i.e., towards the direction of the outer lens 12). Light guide teeth 1312 are formed on the rear side of the light guide 131.

[0042] When the light-emitting element 132 emits light and enters the light guide 131, the light would normally propagate by total internal reflection inside the light guide 131. Because the refractive index of the material of the light guide 131 is different from that of the surrounding medium (air), when the light shines on the interface between the light guide 131 and the surrounding medium at a suitable incident angle, total internal reflection will occur, allowing the light to propagate efficiently along a specific path inside the light guide 131, reducing the loss of light during propagation.

[0043] When light rays propagating along the path of total internal reflection reach the light guide teeth 1312 on the rear side of the light guide 131, the special shape and structure of the light guide teeth 1312 will disrupt the original conditions of total internal reflection. Because the light guide teeth 1312 change the angle and manner in which the light rays are incident on the interface between the light guide 131 and the surrounding medium, some light rays no longer meet the requirements of total internal reflection.

[0044] Once the total internal reflection condition is broken, this portion of the light will change its propagation direction. It will no longer continue to propagate along the original total internal reflection path inside the light guide 131, but will instead be emitted outward from the light guide 131 and propagate in the forward direction. The light emitted from the light guide 131 will diffuse outward and propagate to the outer lens 12 after passing through the arc-shaped surface 1311 that bulges towards the front, thus achieving the daytime illumination function.

[0045] By breaking total internal reflection through the light guide teeth 1312, light is emitted through the curved surface 1311, which can achieve the daytime lighting effect that meets the design requirements, and there is no need to add additional complex optical components. This makes full use of the space of the light guide 131 and helps to realize the miniaturization and compact design of the vehicle lights.

[0046] According to some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the first light guide 111 is configured to be a plurality of light guides spaced apart in the width direction, and the second light guide 112 is configured to be a plurality of light guides, each corresponding to one of the plurality of first light guides 111.

[0047] Multiple first light guides 111 are arranged at intervals in the width direction, which can be matched with multiple light sources 14. Each first light guide 111 independently receives the light emitted by the corresponding light source 14 through its light-receiving surface 1111 at its end, realizing the introduction and efficient utilization of light. Each first light guide 111 independently changes the propagation direction of the received light according to its own optical characteristics and conducts it along a predetermined path.

[0048] Multiple second light guides 112 are connected one-to-one with multiple first light guides 111 at the front end, so that light enters the corresponding second light guide 112 after being guided by the first light guide 111, and is further guided and processed by the second light guide 112, and finally emitted from its light-emitting surface 1121, which helps to achieve a more uniform and controllable light distribution.

[0049] By having multiple first light guides 111 and multiple second light guides 112 cooperate one-to-one, the width of the light pattern is widened, enabling the lighting module 1 to adapt to a wider range of light output requirements.

[0050] According to some embodiments of this utility model, such as Figure 6 As shown, among the adjacent first light guides 111, the light-incoming surfaces 1111 of the two outer first light guides 111 are diffused light-incoming areas 114, and the multiple light-incoming surfaces 1111 of the multiple first light guides 111 located between the diffused light-incoming areas 114 together form a converging light-incoming area 115; wherein, the light-outcoming surface 1121 of the second light guide 112 corresponding to the diffused light-incoming area 114 forms a diffused light-outcoming area, and the light-outcoming surface 1121 of the second light guide 112 corresponding to the converging light-incoming area 115 forms a converging light-outcoming area, and the width of the converging light-outcoming area is greater than the width of the diffused light-outcoming area.

[0051] After light enters the first light guide section 111 through the diffuser zone 114, the first light guide section 111 diffuses the light through its internal optical structure, spreading the light propagation angle within a certain range, thus forming a relatively broad beam distribution in subsequent transmission. When this part of the light finally exits through the diffuser zone corresponding to the diffuser zone 114, its light emission range is widened, which helps to achieve a uniform, soft, and wide lighting effect in the edge area of ​​the headlight illumination pattern.

[0052] Correspondingly, after the light enters the first light guide 111 through the light-converging input area 115, the first light guide 111 uses its internal optical design to converge and concentrate the light, making the light propagation direction more focused and increasing the light energy density. When this part of the light finally exits through the light-converging output area corresponding to the light-converging input area 115, it can form a brighter light spot in the central area, thereby enhancing the illumination distance of the headlights directly in front and the illumination intensity in the central area.

[0053] Because the width of the converging light zone is greater than the diffused light zone, the central area of ​​illumination can cover a wider range while maintaining light concentration and energy density. Therefore, the headlights not only create a bright, wide, and uniform illumination area in the center of the road, but also naturally connect the central bright area with the surrounding dark areas through the outer diffused light zone. This satisfies regulatory requirements for low beam illumination distribution and improves the driver's field of vision and clarity at night, further optimizing the functionality and safety of the headlights.

[0054] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, each first light guide portion 111 has a bottom-convex arc-shaped total internal reflection surface 1112, so the bottom surface of the first light guide portion 111 has an arc shape and is an outwardly convex curved surface when viewed from the side. In the first light guide portion 111, the refractive index of the material of the first light guide portion 111 is greater than the refractive index of air. When light propagates inside the first light guide portion 111 and strikes the bottom arc-shaped total internal reflection surface 1112, total internal reflection occurs.

[0055] The curved total internal reflection surface 1112, bulging towards the bottom, can change the direction of light propagation. When light enters the first light guide 111 from the light-inlet surface 1111, it will strike the curved total internal reflection surface 1112 during its propagation towards the second light guide 112. According to the law of reflection, the light will be reflected on the curved total internal reflection surface 1112. Due to the curvature of the curved total internal reflection surface 1112, the direction of the reflected light will change according to a specific law, so that the light rays striking the curved total internal reflection surface 1112 continue to propagate inside the first light guide 111.

[0056] For light entering from the light-inlet surface 1111 of the first light guide 111, the light will propagate directly towards the bottom. The light will undergo total reflection by the arc-shaped total reflection surface 1112, which will change the direction of propagation and allow it to continue to propagate towards the light-outlet surface 1121 within the first light guide 111. This can adjust the propagation path and angle distribution of the light, so that the light propagates along a preset path, reducing light loss, improving the light utilization rate of the entire lighting module 1, and enhancing the lighting effect.

[0057] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the top of each first light guide 111 is connected to the top of the second light guide 112 and is constructed as a reflective optical surface 113. The reflective optical surface 113 can reflect light according to specific optical laws, change the propagation direction of the light, and make the light propagate in the direction of the light-emitting surface 1121.

[0058] The light reflected by the arc-shaped total internal reflection surface 1112 of the first light guide 111 will propagate toward the reflective optical surface 113. The reflective optical surface 113 changes the propagation direction of the light by reflecting the light, so that the light propagates toward the light emitting surface 1121 of the second light section.

[0059] The angle between the reflective optical surface 113 and the horizontal line is α, satisfying: 43°≤α≤47°. Light rays propagating from the first light guide 111 reach the reflective optical surface 113 and, depending on the angle α, are reflected at a specific angle towards the light-emitting surface 1121. By rationally designing the value of α, the propagation path and emission direction of the light within the second light guide 112 can be controlled, thus achieving light regulation.

[0060] By limiting the value of α to between 43° and 47°, the reflective optical surface 113, after receiving light reflected from the arcuate total reflection surface 1112 at the bottom, can guide the light towards the light-emitting surface 1121 in a horizontal or near-horizontal direction, thereby controlling the propagation path and emission direction of the light in the second light guide 112 and achieving precise control of the light.

[0061] According to some embodiments of this utility model, such as Figure 3 As shown, the bottom surface of the second light guide 112 extends obliquely towards the top in the light emission direction, and the angle between the bottom surface of the second light guide 112 and the horizontal line is β, which satisfies: 0≤β≤12°.

[0062] When the angle β between the bottom surface of the second light guide 112 and the horizontal line is 0, the bottom surface of the second light guide 112 is horizontal, and the propagation path of light on the bottom surface of the second light guide 112 is relatively straight, which is beneficial to maintaining the stability and uniformity of light transmission. When the angle β between the bottom surface of the second light guide 112 and the horizontal line satisfies: 0 < β ≤ 12°, the bottom surface of the second light guide 112 extends obliquely upward in the light-emitting direction. At this time, when the second light guide 112 is viewed from the side, its bottom surface presents an upwardly inclined straight line, forming a guiding surface with a certain elevation angle, which can effectively prevent the light emitted from the light-emitting surface 1121 from propagating towards the bottom.

[0063] By limiting the angle β between the bottom surface of the second light guide 112 and the horizontal line to 0° to 12°, the proportion of light propagating in the second light guide 112 that is directed toward the bottom surface of the second light guide 112 is reduced. This allows more light emitted from the light-emitting surface 1121 to propagate to the outer lens 12. It also effectively avoids interference from the bottom surface of the second light guide 112 with the light propagating in the second light guide 112, ensuring that the light can be efficiently and stably guided to the light-emitting surface 1121 along the expected optical path.
