DETAILED DESCRIPTION
[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.
[0041] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," and "right" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the product of this application is typically placed when in use, and therefore should not be construed as limiting this application. Furthermore, the terms "first," "second," and "third," etc., are used solely for purposes of distinction and should not be construed as indicating or implying relative importance.
[0042] It should also be noted that, in the description of this application, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to direct connection, indirect connection through an intermediate medium, or internal connection between two components. Those skilled in the art will understand the specific meanings of these terms in this application.
[0043] 1 to 5 , one aspect of an embodiment of the present application provides a headlight lighting device, which is installed on a vehicle. The headlight lighting device includes a first headlight module 21 and a second headlight module 22 arranged in the up-down direction of the vehicle. The first headlight module 21 includes a first light source 211, a first reflector 212, and a first lens 11. The second headlight module 22 includes a second light source 221, a second reflector 222, and a second lens 12. The first lens 11 and the second lens 12 are arranged obliquely relative to the horizontal direction. The bodies of the first lens 11 and the second lens 12 extend obliquely. The first lens 11 and the second lens 12 extend obliquely. The first and second lens 12 are each configured with a first total reflection surface and a second total reflection surface. Light emitted by the first light source 211 is reflected by the first reflector 212 before entering the first lens 11. It then passes through the first total reflection surface 111 and the second total reflection surface 112 of the first lens, and then exits from the light-exiting surface of the first lens 11, forming a light pattern. Light emitted by the second light source 221 is reflected by the second reflector 222 before entering the second lens 12. It then passes through the first total reflection surface 121 and the second total reflection surface 122 of the second lens, and then exits from the light-exiting surface of the second lens 12, forming a light pattern. Because the first and second lenses 11 and 12 are tilted relative to the horizontal, a cavity is formed between the first and second lamp modules 21 and 22, which are arranged one above the other. This cavity can accommodate a heat sink, a module that can perform other lighting functions, or other lamp components. This cavity provides a large space, allowing for more flexible arrangement of components within the lamp lighting device.
[0044] 3 and 4 , the first lens 11 and the first reflector 212 are arranged along the front-to-rear direction of the vehicle, and the first light source 211 is disposed on the light incident side of the first reflector 212 ; the second lens 12 and the second reflector 222 are arranged along the front-to-rear direction of the vehicle, and the second light source 221 is disposed on the light incident side of the second reflector 222 . Corresponding to FIG3 , the front-to-rear direction of the vehicle is the first direction a.
[0045] The vehicle lighting device includes a first vehicle light module 21 and a second vehicle light module 22 arranged along the up-down direction of the vehicle. Corresponding to FIG3 , the up-down direction of the vehicle is the second direction b, wherein the second direction b is perpendicular to the first direction a.
[0046] In the present application, the first lens 11 and the second lens 12 are connected as a whole, wherein the first lens 11 and the second lens 12 are distributed along the second direction b. It should be noted that the first lens 11 and the second lens 12 each have two total reflection surfaces (i.e., a first total reflection surface and a second total reflection surface). By configuring the first lens 11 and the second lens 12 as lenses with two total reflection surfaces, the present application facilitates tilting the first lens 11 and the second lens 12 relative to the horizontal direction through two total reflections by the first lens 11 and the second lens 12. The bodies of the first lens 11 and the second lens 12 extend obliquely. Compared to a horizontal arrangement, this allows a cavity to be formed between the first and second headlight modules 21 and 22 arranged vertically. This cavity can accommodate a heat sink, a module capable of performing other lighting functions, or other headlight components. This cavity provides a larger space, allowing for more flexible arrangement of components within the headlight lighting device.
[0047] In addition, it should be noted that the first lens 11 and the second lens 12 are both provided with a first total reflection surface and a second total reflection surface, wherein the first total reflection surface and the second total reflection surface are arranged in parallel or approximately parallel. At this time, those skilled in the art can determine the inclination angle of the first total reflection surface and the second total reflection surface relative to the horizontal plane according to the size of the cavity between the first headlight module 21 and the second headlight module 22. For example, if the required cavity space is larger in the up and down directions of the vehicle, the inclination angle of the first total reflection surface and the second total reflection surface relative to the horizontal plane is large.
[0048] Additionally, the first and second headlight modules 21, 22 of the present application can be configured to implement different lighting functions. For example, the first and second headlight modules 21, 22 can optionally be configured as a low-beam and high-beam modules, respectively. That is, the light pattern emitted by the first headlight module 21 is a low-beam pattern, while the light pattern emitted by the second headlight module 22 is a high-beam pattern. It should be understood that the high-beam module can provide high-beam lighting for the vehicle, while the low-beam module can provide low-beam lighting for the vehicle.
[0049] Taking the first headlight module 21 as a low beam module and the second headlight module 22 as a high beam module as an example, please refer to FIG4 , the working principle of this application is as follows:
[0050] The low beam light emitted by the first light source 211 is reflected by the first reflector 212 and then enters the first lens 11, and is reflected by the first total reflection surface 111 and the second total reflection surface 112 of the first lens in sequence, and then is emitted from the light exit surface of the first lens 11 to form a low beam light pattern; the high beam light emitted by the second light source 221 is reflected by the second reflector 222 and then enters the second lens 12, and is reflected by the first total reflection surface 121 and the second total reflection surface 122 of the second lens in sequence, and then is emitted from the light exit surface of the second lens 12 to form a high beam light pattern.
[0051] In summary, the vehicle lamp lighting device provided by the present application includes a first vehicle lamp module 21 and a second vehicle lamp module 22 arranged along the vertical direction of the vehicle, the first vehicle lamp module 21 has a first light source 211, a first reflector 212 and a first lens 11, the second vehicle lamp module 22 has a second light source 221, a second reflector 222 and a second lens 12, the first lens 11 and the second lens 12 are arranged obliquely relative to the horizontal direction, the bodies of the first lens 11 and the second lens 12 extend obliquely, and the first lens 11 and the second lens 12 are respectively configured with a first Total reflection surface and second total reflection surface, the light emitted by the first light source 211 is reflected by the first reflector 212 and then enters the first lens 11, and then passes through the first total reflection surface 111 and the second total reflection surface 112 of the first lens in sequence, and then is emitted from the light-emitting surface of the first lens 11 to form a light pattern, the light emitted by the second light source 221 is reflected by the second reflector 222 and then enters the second lens 12, and then passes through the first total reflection surface 121 and the second total reflection surface 122 of the second lens in sequence, and then is emitted from the light-emitting surface of the second lens 12 to form a light pattern. In this application, due to the way in which the first lens 11 and the second lens 12 are tilted relative to the horizontal direction, a cavity is formed between the first and second headlight modules 21 and 22 arranged in an upper and lower direction. The cavity can accommodate a radiator, or a module that can realize other lighting functions, or other headlight components. The cavity has a large space, and the arrangement of components in the headlight module lighting device is more flexible.
[0052] In a feasible embodiment, as shown in Figures 3 and 4, the first lens 11 and the second lens 12 are thin lenses with a thinned middle portion. Light is incident from the light-entry surface of the first lens 11 and the second lens 12, undergoes two total reflections respectively, and then exits from the light-exiting surface of the first lens 11 and the second lens 12. While ensuring the same size of the light-entry and light-exiting surfaces and the same optical path as traditional thick-walled lenses, the effect of thinning the lens and reducing the weight of the lens is achieved. Furthermore, as shown in Figure 13, the first angle c and the first angle d satisfy the following formula: c = 90° - 2×d, where c is the first angle and d is the first angle (i.e., the angle between the first total reflection surface and the horizontal plane). In this embodiment, the first angle d is preferably between 0° and 45°.
[0053] The first distance d3 and the second distance D satisfy the following formula: d3 = D / cosc × sind. The first distance d3 is the distance between the upper and lower surfaces of the first lens 11 or the second lens 12 (i.e., the lens thickness, which is the thickness of the remaining portion of the first lens 11 or the second lens 12 excluding the light incident and light exit surfaces, and is also the distance between the first total reflection surface 111 and the second total reflection surface 112). D is the dimension of the lens' light incident surface along the vehicle height direction. The first lens 11 or the second lens 12 can be simply viewed as a virtual lens 40 mirrored relative to the first total reflection surface 111 and then relative to the second total reflection surface 112.
[0054] In one feasible embodiment, as shown in Figures 4 and 5 , the light entrance and exit surfaces of the first lens 11 and the second lens 12 can be unidirectional collimating surfaces, i.e., cylindrical or quasi-cylindrical surfaces. For example, the light entrance surface of the first lens 11 is a longitudinally stretched surface to collimate the light in the horizontal direction, and the light exit surface of the first lens 11 is a transversely stretched surface to collimate the light in the longitudinal direction.
[0055] In a feasible embodiment, as shown in Figures 6 and 7, the first light source 211 can be a plurality of LEDs arranged in parallel on a circuit board. In this case, the first reflector 212 correspondingly includes a plurality of sub-reflectors arranged in parallel (as shown in Figure 8) for respectively reflecting the light emitted by each LED. Similarly, as shown in Figure 10, the second light source 221 can also be a plurality of LEDs arranged in parallel on a circuit board. In this case, the second reflector 222 can also include a plurality of sub-reflectors arranged in parallel (as shown in Figure 9) for respectively reflecting the light emitted by each LED.
[0056] Optionally, the reflective surfaces of the first reflector 212 and the second reflector 222 are parabolic, quasi-parabolic, ellipsoidal, or quasi-ellipsoidal surfaces. The reflective surfaces of the first reflector 212 and the second reflector 222 can be the same or different. It should be noted that a quasi-parabolic surface is a surface that is similar to a parabola, and a quasi-ellipsoidal surface is a surface that is similar to an ellipsoidal surface, both of which have similar optical properties.
[0057] In the present application, optionally, as shown in FIG. 4 , the light emitting side of the first light source 211 faces the first reflector 212 and away from the second light source 221 , and the light emitting side of the second light source 221 faces the second reflector 222 and away from the first light source 211 .
[0058] Referring to Figures 4, 11, and 12, the vehicle lighting device optionally further includes a third vehicle lighting module 23 disposed between the first vehicle lighting module 21 and the second vehicle lighting module 22. The third vehicle lighting module 23 includes a third light source 231, a third reflector 232, and a third lens 13. Light emitted by the third light source 231 is reflected by the third reflector 232 and then incident on the third lens 13. Light is then transmitted through the third lens 13 and then emitted to form a light pattern. The third vehicle lighting module 23 can achieve a different lighting function than the first vehicle lighting module 21 and the second vehicle lighting module 22.
[0059] In the present application, the light emitted by the third light source 231 can be directly transmitted through the third lens 13 after being reflected by the third reflector 232 .
[0060] Optionally, the light incident surface of the third lens 13 is a collimating curved surface, and the light emitting surface of the third lens 13 is a plane, a transversely stretched cylindrical surface, or a transversely stretched cylindrical-like surface, so as to form the focus of the third lens 13 in conjunction with the light incident surface.
[0061] Optionally, the reflective surface of the third reflector 232 is a parabola, a quasi-parabola, an ellipsoid, or a quasi-ellipsoid. Specific surface shape can be selected and determined by those skilled in the art according to needs, and this application does not impose any restrictions, as long as it can reflect the light emitted by the third light source 231.
[0062] Optionally, the above-mentioned third headlight module 23 is a main low beam module. In this case, the first headlight module 21 can be an auxiliary low beam module, and the second headlight module 22 can be a high beam module. In this case, the headlight lighting device of the present application includes an auxiliary low beam module, a main low beam module and a high beam module arranged along the upper and lower directions of the vehicle.
[0063] To make the structure of the vehicle lighting device provided in this application relatively more compact, the first lens 11, the third lens 13, and the second lens 12 are optionally connected in sequence to form an integral body. The light-emitting surfaces of the first lens 11, the third lens 13, and the second lens 12 are connected to form a smooth cylindrical surface or a smooth cylindrical surface. The smooth cylindrical surface or smooth cylindrical surface has a converging effect on light. To facilitate heat dissipation of the vehicle lighting device, in this application, the vehicle lighting device may also optionally include a heat sink, which is disposed between the first vehicle lighting module 21 and the second vehicle lighting module 22 and is configured to dissipate heat for the vehicle lighting device.
[0064] Optionally, the radiator includes a first radiator 31 and a second radiator 32, wherein the first radiator 31 is disposed between the first light module 21 and the third light module 23, and the second radiator 32 is disposed between the second light module 22 and the third light module 23. By providing two radiators, the present application can further improve heat dissipation efficiency.
[0065] In addition, it should be noted that, as shown in Figures 3 and 4, the side of the first radiator 31 away from the second radiator 32 can be connected to the circuit board of the first headlight module 21, the side of the second radiator 32 away from the first radiator 31 can be connected to the circuit board of the second headlight module 22, and the side of the second radiator 32 close to the first radiator 31 can be connected to the circuit board of the third headlight module 23.
[0066] Among them, the connection method between the above-mentioned radiator and the circuit board of the corresponding headlight module can be fixed with fixing parts, or can be fastened with a snap or other methods, and this application does not make specific restrictions.
