[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "top surface", "bottom surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0043] Such as Figures 1-9As shown in the figure, the dual-light module structure disclosed by the present utility model includes a low-beam module 100, a high-beam module 200, and a focal-line free-form lens 300. The low-beam module 100 is used to form a low-beam light pattern, and the high-beam module 200 is used to form a high-beam light pattern. The low-beam module 100 and the high-beam module 200 are arranged side by side. The low-beam module 100 includes a low-beam TIR total reflection surface 101, and the edge 106 of the low-beam TIR total reflection surface 101 coincides with the focal-line position 301 of the focal-line free-form lens 300. Specifically, the low-beam module 100 includes a low-beam free-form lens group inner lens, which has a low-beam inner lens light-emitting surface, and the high-beam module 200 includes a high-beam free-form lens group inner lens, which has a high-beam inner lens light-emitting surface. In the dual-light module structure provided by the present utility model, during use, the edge 106 of the low-beam TIR total reflection surface 101 coincides with the focal-line position 301 of the focal-line free-form lens 300, which can form a low-beam cut-off line, that is, the baffle for blocking the light pattern is cancelled, and the light utilization rate can also be improved. The light is totally reflected by the low-beam TIR total reflection surface 101 and then focused by the focal-line free-form lens 300 to form a low-beam light pattern. The high-beam module 200 and the focal-line free-form lens 300 cooperate to form a high-beam light pattern. Because the low-beam module 100 and the high-beam module 200 are arranged side by side, a super-narrow dual-light module structure is formed, and the blocking member is cancelled, so the volume of the module is reduced.

[0044] To optimize the above technical solution, the high-beam module 200 includes a high-beam TIR total reflection surface 201 and a high-beam TIR incident light surface 202. The high-beam TIR incident light surface 202 is a concave surface, and the low-beam module 100 further includes a low-beam TIR incident light surface 102, and the low-beam TIR incident light surface 102 is a flat surface. Specifically, by arranging the high-beam TIR total reflection surface 201 and the low-beam TIR total reflection surface 101, the refracted light is reduced, and the utilization rate of the totally reflected light is improved, which can effectively improve the brightness of the light pattern. During use, the light enters from the high-beam TIR incident light surface 202 and the low-beam TIR incident light surface 102 at the same time, and then is totally reflected by the high-beam TIR total reflection surface 201 and the low-beam TIR total reflection surface 101 respectively, and exits from the high-beam inner lens light-emitting surface and the low-beam inner lens light-emitting surface respectively, and then enters the focal-line free-form lens 300 for focusing. The high-beam light is emitted as parallel light, and the low-beam light is emitted as non-parallel light. Because the baffle is cancelled, the high-beam can form a complete light pattern, and when the high-beam light pattern is superimposed with the low-beam light pattern, there is no dark area, thus ensuring the light utilization rate.

[0045] To optimize the above technical solution, the high beam module 200 further includes a high beam TIR light-emitting surface 203, which is a concave surface. The low beam module 100 further includes a low beam TIR light-emitting surface 103, which is composed of a plurality of convex units. Specifically, the high beam TIR light-emitting surface 203 is the above-mentioned high beam inner lens light-emitting surface, and the low beam TIR light-emitting surface 103 is the above-mentioned low beam inner lens light-emitting surface. The operator can change the shapes of the high beam TIR light-emitting surface 203 and the plurality of convex units according to the reflection requirements. Specifically, the shapes of the plurality of convex units can be customized according to the requirements of the light pattern solution to form different low beam light patterns.

[0046] To optimize the above technical solution, the focal line free-form lens 300 is arranged on the light-emitting paths of the high beam TIR light-emitting surface 203 and the low beam TIR light-emitting surface 103. Specifically, the wall thickness of the focal line free-form lens 300 is thinner and more uniformly variable than that of a conventional lens or a combination of multiple lenses. Specifically, the focal line free-form lens 300 is an outer lens and there is only one, that is, the low beam module 100 and the high beam module 200 share one outer lens. The high beam can generate a complete light pattern. After being superimposed with the low beam light pattern, there is no dark area in the overall light pattern, thereby improving the customer's sensory performance and at the same time enhancing the road illumination performance of the dual-beam module structure.

[0047] To optimize the above technical solution, there is an included angle between the low beam module 100 and the high beam module 200. Specifically, the operator can change the included angle between the low beam module 100 and the high beam module 200 according to the usage requirements, thereby changing the positions of the low beam light pattern and the high beam light pattern, and thus changing the overall light pattern after the dual-beam module structure is lit.

[0048] To optimize the above technical solution, the low beam module 100 further includes a plurality of low beam reflecting bowls 104 arranged side by side, and the high beam module 200 further includes a plurality of high beam reflecting bowls 204 arranged side by side. Specifically, the operator can change the numbers and arrangement positions of the low beam reflecting bowls 104 and the high beam reflecting bowls 204 according to the usage requirements. It should be noted that the above "arranged side by side" and the "arranged side by side" of the low beam module 100 and the high beam module 200 are macroscopic arrangement schemes, and they do not necessarily have to be arranged in a straight line. As long as the plurality of low beam reflecting bowls 104 can be placed left and right, the plurality of high beam reflecting bowls 204 can be placed left and right, and the low beam module 100 and the high beam module 200 can be placed left and right.

[0049] To optimize the above technical solution, the dual-light module structure further includes a PCB board 400, a plurality of low-beam light sources 105 and a plurality of high-beam light sources 205. The low-beam light sources 105 and the high-beam light sources 205 are both arranged on the PCB board 400, and the positions of the low-beam light sources 105 correspond to those of the low-beam module 100, and the positions of the high-beam light sources 205 correspond to those of the high-beam module 200. Specifically, it is preferred that both the low-beam light sources 105 and the high-beam light sources 205 are LED light sources. Specifically, the operator can change the arrangement positions and angles of the low-beam light sources 105 and the high-beam light sources 205 according to the usage needs, and can also change the arrangement position and shape of the PCB board 400 according to the usage needs to adapt to the high-beam module 200 and the low-beam module 100. Specifically, the high-beam module 200 and the low-beam module 100 share a PCB board 400 to further reduce the module volume. Specifically, the light emitted by the high-beam light sources 205 basically passes through the high-beam TIR total reflection surface 201, which can ensure that the light spot is a circle or an ellipse, which is more beneficial to road illumination and regulations, and is also beneficial to the improvement of brightness, realizing the effective utilization of light.

[0050] To optimize the above technical solution, the dual-light module structure further includes a controller. The controller is electrically connected to the PCB board 400. When the dual-light module structure is in the first working condition, the controller controls the low-beam light sources 105 to light up and the high-beam light sources 205 to turn off. When the dual-light module structure is in the second working condition, the controller controls the high-beam light sources 205 to light up and the low-beam light sources 105 to turn off. When the dual-light module structure is in the third working condition, the controller controls the low-beam light sources 105 and the high-beam light sources 205 to light up. When the dual-light module structure is in the fourth working condition, the controller controls the low-beam light sources 105 and the high-beam light sources 205 to turn off. Specifically, by arranging the controller, the dual-light module structure can meet a variety of application scenarios, making the use of the dual-light module structure more flexible.

[0051] To optimize the above technical solution, the PCB board 400 is arranged in parallel with the high-beam TIR light incident surface 202 and / or the low-beam TIR light incident surface 102. On the one hand, the PCB board 400 and the high-beam TIR light incident surface 202 and / or the low-beam TIR light incident surface 102 can both be arranged obliquely. On the other hand, the PCB board 400 and the high-beam TIR light incident surface 202 and / or the low-beam TIR light incident surface 102 can both be arranged vertically to realize the folding of the light path, shorten the module length, and thus reduce the module volume.

The number of low-beam modules 100 is one or more, the number of high-beam modules 200 is one or more, and the number of focus-free freeform lenses 300 is one.
