[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] As described in the background technology, with the development of automobile lighting technology, the Adaptive Driving Beam (ADB) system came into being. With the cooperation of the vehicle's front camera, it can automatically control the brightness of the high beam, while ensuring the driver's clear vision, forming a dark area in the area where there are vehicles, and will not dazzle the drivers of other vehicles on the road. Although there are many advantages to using the adaptive high beam system in the headlights, the performance of existing headlights needs to be improved. For example, the low beam module and the ADB module in the existing headlights share the focus lens, which causes the headlights to have problems such as light pattern splicing, severe dispersion, and splicing dark lines.

[0049] Based on this, the embodiments of the present application provide a dual-light module and a headlight, which effectively solve the technical problems existing in the prior art, and adopt a multi-focus lens module to receive the output light of the ADB lens and the low beam lens, so that the focus of the lens modules corresponding to the low beam module and the ADB module are separated, thereby avoiding the problems of light shape splicing, splicing dark lines, severe dispersion, etc. caused by the low beam module and the ADB module sharing the focus lens, thereby improving the performance of the headlight.

[0050] To achieve the above purpose, the technical solution provided in the embodiment of the present application is as follows, specifically combined with Figures 1 to 13 The technical solution provided in the embodiments of the present application is described in detail.

[0051] Combination Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the structure of a dual-light module provided in an embodiment of the present application is shown in FIG. Figure 2 The optical path diagram of a dual-module provided in an embodiment of the present application. The dual-optical module provided in an embodiment of the present application includes:

[0052] An ADB light source 110, a low beam light source 210, an ADB lens 120, a low beam lens 220 and a multi-focal lens module 300, wherein the multi-focal lens module 300 includes a first lens module 301 and a second lens module 302, wherein the first focus F1 of the first lens module 301 and the second focus F2 of the second lens module 302 are different; the ADB lens 120 is connected to the outgoing light of the ADB light source 110, and the outgoing light of the ADB lens 120 is emitted as an ADB light shape after passing through the first lens module 301; the low beam lens 220 is connected to the outgoing light of the low beam light source 210, and the outgoing light of the low beam lens 220 is emitted as a low beam light shape after passing through the second lens module 302, wherein the light shape is the shape of the light spot.

[0053] It can be understood that when the ADB light source 110 provided in the embodiment of the present application is turned on to emit light, the light emitted by the ADB light source 110 is irradiated into the ADB lens 120, and after passing through the ADB lens 120, the light emitted by the ADB lens 120 is irradiated into the first lens module 301, and after passing through the first lens module 301, it is emitted as an ADB light shape. Also, when the low-beam light source 210 is turned on to emit light, the light emitted by the low-beam light source 210 is irradiated into the low-beam lens 220, and after passing through the low-beam lens 220, it is emitted as a low-beam light shape. The low-beam lens 220 irradiates the light emitted by the low-beam lens 220 into the second lens module 302, and after passing through the second lens module 302, it is emitted as a low-beam light shape, thereby realizing dual-light control of the module. Optionally, the ADB light source 110 and the low beam light source 210 provided in the embodiment of the present application can be turned on separately, or the ADB light source 110 and the low beam light source 210 can be turned on in combination, which needs to be specifically controlled according to the actual application, and the present application does not make any specific restrictions.

[0054] It can be seen from the above content that the technical solution provided in the embodiment of the present application adopts a multi-focal lens module 300 to receive the output light of the ADB lens 120 and the low beam lens 220, so that the focus of the lens modules corresponding to the low beam module and the ADB module are separated, which is equivalent to the low beam module and the ADB module corresponding to their own independent focus lenses, and the high and low beams are designed separately and do not affect each other, thereby avoiding the problems of light shape splicing, splicing dark lines, severe dispersion, etc. caused by the low beam module and the ADB module sharing the focus lens, thereby improving the performance of the car lights.

[0055] The following is a more detailed description of the ADB light source 110, the low beam light source 210, the ADB lens 120, the low beam lens 220 and the multi-focal lens module 300 provided in the embodiment of the present application in conjunction with the accompanying drawings. Figures 1 to 7 As shown, Figure 3 This is a rear view of a multifocal lens provided in an embodiment of the present application. Figure 4 A side view of a multifocal lens provided in an embodiment of the present application, Figure 5 A top view of a multifocal lens provided in an embodiment of the present application, Figure 6 This is a rear view of a light output lens provided in an embodiment of the present application. Figure 7 A side view of a light-emitting lens provided in an embodiment of the present application. The multifocal lens module 300 provided in an embodiment of the present application may include a multifocal lens 310 and a light-emitting lens 320, wherein the light-emitting lens 320 is located at the light-emitting side of the multifocal lens 310; the multifocal lens 310 includes a first lens portion 311 and a second lens portion 312, wherein the first lens portion 311 and the light-emitting lens 320 constitute the first lens module 301, and the second lens portion 312 and the light-emitting lens 320 constitute the second lens module 302.

[0056] It can be understood that the multifocal lens 310 provided in the embodiment of the present application is composed of a first lens portion 311 of the upper part and a second lens portion 312 of the lower part. The light emitted by the ADB lens 120 is irradiated to the light incident surface of the first lens portion 311 and enters the lens, and then is emitted from the light exit surface of the first lens portion 311 to the light exit lens 320. Also, the light emitted by the low beam lens 220 is irradiated to the light incident surface of the second lens portion 312 and enters the lens, and then is emitted from the light exit surface of the second lens portion 312 to the light exit lens 320. Therefore, the multi-focal lens module 300 is used to receive the emitted light of the ADB lens 120 and the low beam lens 220, so that the focus of the lens modules corresponding to the low beam module and the ADB module are separated, which is equivalent to the low beam module and the ADB module corresponding to their own independent focus lenses, and the high and low beams are designed independently without affecting each other, thereby avoiding the problems of light shape splicing, splicing dark lines, and severe dispersion caused by the low beam module and the ADB module sharing the focus lens, thereby improving the performance of the car light. In particular, the multi-focal lens 310 used is a lens with an integrated appearance spliced ​​by the first lens portion 311 and the second lens portion 312, which meets the requirements of performance and shape; wherein, the positions of the first focus F1 and the second focus F2 can be controlled by adjusting the curved surface shapes of the first lens portion 311 and the second lens portion 312 of the multi-focal lens 310.

[0057] like Figure 3 and Figure 4As shown, the first lens portion 311 provided in the embodiment of the present application has a focusing effect. The light emitted by the ADB lens 120 passes through the first lens module 301 and then is emitted in parallel, so it is suitable for the ADB module design. Therefore, the first lens portion 311 can be a focal lens, such as the first lens portion 311 is a convex lens. The light emitted by the low beam lens 220 can maintain its optical path unchanged after passing through the second lens module 302, and is used for the low beam module design. Therefore, the second lens portion 312 can be a focal line lens, such as the second lens portion 312 is an equal thickness lens. Among them, the light emitting surfaces of the first lens portion 311 and the second lens portion 312 are spliced ​​into the same surface. As Figure 6 and Figure 7 As shown, the light-emitting lens 320 provided in the embodiment of the present application can be a concave lens, and thus can receive more light. Therefore, the opening size of the multifocal lens 310 provided in the embodiment of the present application can be designed to be larger than the opening size of the light-emitting lens 320, that is, the height and width of the multifocal lens 310 are larger than the height and width of the light-emitting lens 320, thereby achieving a smaller opening size of the light-emitting lens 320 and improving the light-emitting effect of the car lights.

[0058] The first lens portion 311 provided in the embodiment of the present application has a plurality of uniform light patterns formed on its light emitting surface 311a side, and the uniform light patterns are used to uniform the light when the first lens portion 311 emits light, so as to improve the uniformity of the ADB light shape. Optionally, the uniform light patterns formed on the light emitting surface 311a of the first lens portion 311 provided in the embodiment of the present application may be composed of a plurality of curved surface patterns, and the sizes of different curved surface patterns may be the same or different. Similarly, the light emitting lens 320 provided in the embodiment of the present application has a plurality of uniform light patterns formed on its light emitting surface 320a side, so as to optimize the uniformity of the ADB light shape and the cutoff line gradient of the low beam light shape. Optionally, the uniform light patterns formed on the light emitting surface 320a of the light emitting lens 320 provided in the embodiment of the present application may be composed of a plurality of curved surface patterns, and the sizes of different curved surface patterns may be the same or different.
