[0002] Among existing vehicle lighting systems, cornering lights play a crucial role. They not only improve visibility in poor conditions such as fog, rain, or nighttime, but also provide auxiliary lighting at corners, better illuminating the road ahead and offering drivers a wider field of vision. Consequently, cornering lights are increasingly widely used in various vehicle types, including passenger cars and commercial vehicles. Especially in the fields of new energy vehicles and intelligent driving vehicles, cornering lights are increasingly incorporating intelligent technologies, such as adaptive high beams, which automatically adjust the brightness and range of light according to road conditions and driving conditions, improving driving safety and comfort.

[0035] The specific embodiments of this application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this application, and the scope of protection of this application is not limited to the specific embodiments described below.
[0036] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0037] like Figure 1 and Figure 2 As shown, this application provides an optical module, including a first optical component and a second optical component. The first optical component is used to realize a first optical function, and the first optical component includes a first primary optical unit 1 and a first secondary optical unit 2, through which light is emitted sequentially.
[0038] The second optical component is used to realize the corner light function. The second optical component includes a second primary optical unit 3 and a second secondary optical unit 4. The light is emitted sequentially through the second primary optical unit 3 and the second secondary optical unit 4.
[0039] The first primary optical unit 1 and the second primary optical unit 3 are integrally formed, and some optical components in the first primary optical unit 2 and some optical components in the second primary optical unit 4 are integrally formed.
[0040] Therefore, this application integrates the first and second optical components, improving the space utilization of the vehicle headlights while further reducing assembly steps and saving on component costs through a one-piece molding.
[0041] As a specific embodiment of this application, a first optical component is used to implement a first light function, including a low beam illumination function and / or a high beam illumination function. A second optical component is used to implement a cornering light function. Thus, the cornering light function can be integrated into the optical module of the low beam illumination function and / or high beam illumination function.
[0042] In a preferred embodiment of this application, the first-stage optical unit 2 includes at least a first outer lens 201, and the second-stage optical unit 4 includes at least a second outer lens 401, wherein the first outer lens 201 and the second outer lens 401 are integrally formed. Figure 1 As shown, the first outer lens 201 and the second outer lens 401 are integrally formed, which can effectively reduce the installation difficulty of the first-stage optical unit 2 and the second-stage optical unit 4, improve the installation accuracy, and simplify the manufacturing process, effectively saving production and installation costs. At the same time, the first optical component and the second optical component can be linked to achieve seamless illumination coverage, effectively improving the compactness of the entire optical module without affecting the light output effect.
[0043] In a preferred embodiment of this application, the light-emitting surfaces of the integrally formed first outer lens 201 and second outer lens 401 together form a lens light-emitting surface, which has a smooth surface. With the first outer lens 201 and second outer lens 401 integrally formed, the light-emitting surfaces of both can be formed as smooth surfaces, thus maintaining the consistency of the optical module's appearance and enhancing its technological design.
[0044] In a preferred embodiment of this application, the light-incident surface of the second outer lens 401 and the light-incident surface of the first outer lens 201 have a height difference, and the light-incident surface of the second outer lens 401 and the light-incident surface of the first outer lens 201 have different surface shapes. Since the first optical component and the second optical component perform different optical functions, targeted light distribution adjustments can be made to the light-incident surfaces of the second outer lens 401 and the first outer lens 201. For example, the light-incident surface of the first outer lens 201 can be formed as multiple continuously curving convex surfaces; specifically, it can be designed as a freeform surface. By differentiating the light-incident surfaces of the second outer lens 401 and the first outer lens 201, the optical module can achieve a large-angle emission effect for corner lamp functions. For lenses with smooth light-emitting surfaces, the surface shape design of the light-incident surfaces of the second outer lens 401 and the first outer lens 201 is particularly important for the light emission effect. Furthermore, the design of the light-incident surface of the second outer lens 401 and the light-incident surface of the first outer lens 201 is particularly suitable for the integration of corner lamp function and high / low beam function in narrow aperture modules.
[0045] In a preferred embodiment of this application, the first primary optical unit 2 further includes a first inner lens 202, which is located between the first primary optical unit 1 and the first outer lens 201 in the light emission direction; and / or the second primary optical unit 4 further includes a second inner lens 402, which is located between the second primary optical unit 3 and the second outer lens 401 in the light emission direction.
[0046] like Figure 1 As shown, the first-stage optical unit 2 includes a first inner lens 202 and a first outer lens 201. The first inner lens 202 is located between the first primary optical unit 1 and the first outer lens 201 in the light emission direction. The second-stage optical unit 4 includes a second inner lens 402 and a second outer lens 401. The second inner lens 402 is located between the second primary optical unit 3 and the second outer lens 401 in the light emission direction. In some variations, the first-stage optical unit 2 includes both the first inner lens 202 and the first outer lens 201, while the second-stage optical unit 4 includes only the second outer lens 401. Alternatively, the second-stage optical unit 4 includes both the second inner lens 402 and the second outer lens 401, while the first-stage optical unit 2 includes only the first outer lens 201. By incorporating inner lenses in the first-stage optical unit 2 and / or the second-stage optical unit 4, on the one hand, the optical surface for adjusting the light pattern can be increased, facilitating light pattern adjustment; on the other hand, compared to a single lens, a dual-lens configuration can reduce the lens thickness and lower lens costs. Furthermore, since the first light function and the corner light function perform different functions, it can be determined whether the first-stage optical unit 2 and the second-stage optical unit 4 need to be equipped with inner lenses according to actual needs.
[0047] In a preferred embodiment of this application, the first inner lens 202 and the second inner lens 402 are integrally formed. The integral formation of the first inner lens 202 and the second inner lens 402, and the integral formation of the first outer lens 201 and the second outer lens 401, simplifies the manufacturing and assembly processes of the first inner lens 202 and the second inner lens 402, and the first outer lens 201 and the second outer lens 401, thereby reducing production costs.
[0048] In a preferred embodiment of this application, the light-incident surfaces of the integrally formed first inner lens 202 and second inner lens 402 together form a lens light-incident surface, which has a smooth surface. In some variations of this application, the light-exiting surfaces of the first inner lens 202 and second inner lens 402 together form an inner lens light-exiting surface, which also has a smooth surface. Many more variations can be implemented in this application, which will not be elaborated upon here.
[0049] In a preferred embodiment of this application, the light-emitting surface of the second inner lens 402 and the light-emitting surface of the first inner lens 202 are both convex curved surfaces. Thus, they can be combined with the light-incident surfaces of the second outer lens 401 and the first outer lens 201 respectively to form light patterns with different functions.
[0050] In a preferred embodiment of this application, there are multiple first optical components. A light-shielding plate 5 is provided between the multiple first optical components and / or between the second optical component and an adjacent first optical component. The light-shielding plate 5 has a cutoff line structure for the first light function and / or the corner lamp function. Thus, the light emitted from the light source corresponding to the first optical component is focused at the focal point of the first inner lens 202 after passing through the focal point of the first primary optical unit 1. After passing through the light-shielding plate 5 and the first outer lens 201, it forms a near beam or far beam pattern with a cutoff line structure. In a specific embodiment of this application, the first optical component forming the far beam pattern can be defined as a far beam optical module, and the first optical component forming the near beam pattern can be defined as a near beam optical module. Therefore, by placing the far beam optical module below the near beam optical module and the second optical component below the far beam optical module, the far beam pattern can be imaged above the near beam pattern, and corner lamp illumination pattern is also provided. The arrangement order of the near-beam optical module, the far-beam optical module, and the second optical component is not limited to this; this application can achieve many more variations, which will not be elaborated here.
[0051] In a preferred embodiment of this application, when the optical module is installed on a vehicle, the first optical component and the second optical component are arranged in the vertical direction of the vehicle.
[0052] In a preferred embodiment of this application, when the optical module is installed on a vehicle, the second optical component is located below the first optical component.
[0053] Specifically, when the optical module is installed in a vehicle, the vertical direction of the vehicle is the vertical direction from the roof to the floor / from the floor to the roof. The vertical direction described in this application is not necessarily completely parallel to the vertical direction; it can include directions within a certain angle range from the vertical direction, such as within 20 degrees, i.e., a tendency towards vertical alignment. This allows for the vertical integration of the second optical component with the first optical component, achieving the large-angle illumination function in a narrow-aperture vertical strip-type optical module, while also simplifying the structure of the optical module and reducing production costs.
[0054] In a preferred embodiment of this application, the first primary optical unit 1 and / or the second primary optical unit 3 include at least one condenser. When both the first primary optical unit 1 and the second primary optical unit 3 are condensers, it facilitates the integral forming of the first primary optical unit 1 and the second primary optical unit 3.
[0055] As a relatively preferred embodiment of the optical module of this application, the optical module of this application includes a first optical component and a second optical component. There are multiple first optical components, and a light-shielding plate 5 is provided between the multiple first optical components and / or between the second optical component and an adjacent first optical component. The light-shielding plate 5 is provided with a cutoff line structure for a first light function and / or a corner lamp function. Each first optical component includes a first primary optical unit 1 and a first secondary optical unit 2. The second optical component includes a second primary optical unit 3 and a second secondary optical unit 4. The first primary optical unit 1 and / or the second primary optical unit 3 include at least one condenser, and the first primary optical unit 1 and the second primary optical unit 3 are integrally formed. The first secondary optical unit 2 includes a first outer lens 201 and a first inner lens 202. The first inner lens 202 is located between the first primary optical unit 1 and the first outer lens 201 in the light emission direction. The second secondary optical unit 4 includes a second outer lens 401 and a second inner lens 402. The second inner lens 402 is located between the first primary optical unit 1 and the first outer lens 201 in the light emission direction. The first outer lens 201 and the second outer lens 401 are located between the second primary optical unit 3 and the second outer lens 401 in the direction of light emission. The first inner lens 202 and the second inner lens 402 are integrally formed. The light-emitting surfaces of the integrally formed first outer lens 201 and the second outer lens 401 together form the light-emitting surface of the lens, which has a smooth surface. The light-incident surface of the second outer lens 401 and the light-incident surface of the first outer lens 201 form a height difference, and the light-incident surface of the second outer lens 401 and the first outer lens 201 are also adjacent to each other. The light-incident surfaces have different surface shapes; the light-incident surfaces of the integrally formed first inner lens 202 and second inner lens 402 together form the lens light-incident surface, which has a smooth surface. The light-exiting surfaces of the second inner lens 402 and the first inner lens 202 are both convex curved surfaces. There are multiple first optical components, and light-shielding plates 5 are provided between the multiple first optical components and / or between the second optical components and adjacent first optical components. The light-shielding plates 5 are provided with cut-off line structures for the first light function and / or cornering light function. When the optical module of this application is installed on a vehicle, the first optical components and the second optical components are arranged in the vertical direction of the vehicle, and the second optical components are located below the first optical components. The first optical components are used to realize the first light function, and the second optical components are used to realize the cornering light function.
[0056] The optical module of this application has the following advantages:
[0057] First, in the optical module of this application, the first optical component is used to form a low beam and / or a high beam, and the second optical component is used to form a cornering light illumination pattern. When the optical module is installed on a vehicle, the first optical component and the second optical component are arranged vertically with the second optical component positioned below the first optical component. This enables the vertical integration design of the second optical component and the first optical component, realizing the large-angle illumination function in the narrow-aperture vertical strip type module of the optical module. It also simplifies the structure of the optical module and reduces production costs.
[0058] Secondly, in this application, the first primary optical unit 1 and the second primary optical unit 3 are integrally formed, the first outer lens 201 and the second outer lens 401 are integrally formed, and the first inner lens 202 and the second inner lens 402 are integrally formed. This allows the light-emitting surface of the first outer lens 201 to be connected with the light-emitting surface of the second outer lens 401 to form a plane, thereby achieving consistency in the appearance of the optical module in the vehicle headlight, improving the appearance, increasing the integration of each component, improving installation accuracy, reducing installation difficulty, and reducing production costs.
[0059] Third, the light sources corresponding to the first optical component and the second optical component are both integrated on the circuit board, which is mounted on the heat sink. This avoids efficiency loss and increased heat dissipation pressure caused by the crossover of integrated optical paths, effectively improving the service life of the optical module.
[0060] Fourth, by highly integrating the second optical component with the first optical component, the illumination gap between the low beam pattern and the cornering light pattern formed by the independent cornering light component can be eliminated, thereby achieving a smooth brightness gradient from the front to the side and effectively improving driving safety performance.
[0061] A second aspect of this application also provides a vehicle lighting fixture, including an optical module according to any one of the above technical solutions;
[0062] The first light source is configured corresponding to the first optical component;
[0063] The second light source is set in accordance with the second optical component.
[0064] As a specific embodiment of this application, it also includes a heat sink and a circuit board disposed on the heat sink. Both the first light source and the second light source are disposed on the circuit board. By sharing the circuit board and the heat sink, the integration level is higher, which can realize the miniaturization design of the vehicle lamp structure and significantly reduce the volume of the optical module.
[0065] Furthermore, a third aspect of this application also provides a vehicle, including vehicle lights according to the above-described technical solution.
[0066] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.
[0067] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.
[0068] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
