[0035] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0036] Please refer to Figure 1 and Figure 2 The lens 100 of the present application includes a first light control part 1, a second light control part 2 and a third light control part 3 which are arranged adjacent to each other. The first light control part 1 is used to project the light generated by the first low-beam light source 5, the second light control part 2 is used to project the light generated by the second low-beam light source 6, and the third light control part 3 is used to project the light generated by the high-beam light source 7. The third light control part 3 is located between the first light control part 1 and the second light control part 2, and the center points of the first light control part 1, the second light control part 2 and the third light control part 3 are not on the same straight line. In this embodiment, the shapes of the first light control part 1, the second light control part 2 and the third light control part 3 are not limited, and the first light control part 1, the second light control part 2 and the third light control part 3 can be bowl-shaped, conical or other shapes.

[0037] In the present embodiment, by integrating the first light-controlling part 1, the second light-controlling part 2 and the third light-controlling part 3 on the same lens 100, one lens 100 can simultaneously project the light generated by the high-beam light source unit 7 and the two low-beam light source units, which can save the number of lenses 100 and simplify the structure of the lamp; in addition, the connecting lines of the center points of the first light-controlling part 1, the second light-controlling part 2 and the third light-controlling part 3 form a triangle, and the third light-controlling part 3 is located between the first light-controlling part 1 and the second light-controlling part 2, which can reduce the number of the first light-controlling part 1, the second light-controlling part 2 and the third light-controlling part 3. The space occupied by the gap between the first light-controlling part 1, the second light-controlling part 2 and the third light-controlling part 3 is reduced, and the layout between the first light-controlling part 1, the second light-controlling part 2 and the third light-controlling part 3 is reasonable and compact, which is conducive to the miniaturization of the volume of the lens 100, thereby reducing the occupied space of the lamp; in addition, compared with a high beam or a low beam lamp with a single light source of the same volume, the lens 100 of the present application allows the lamp to be simultaneously provided with two low beam light source components and one high beam light source component in a limited space, which can effectively improve the lighting brightness and practicality of the lamp.

[0038] In one embodiment, please refer to Figure 1 and Figure 2, the first light control part 1 and the second light control part 2 are relatively distributed on both sides of the lens 100 along a first direction, the first direction is perpendicular to the central axis direction of the lens 100, a mirror plane (not shown in the figure) is provided between the first light control part 1 and the second light control part 2, the mirror plane is parallel to the central axis of the lens 100, and the structure of the first light control part 1 and the structure of the second light control part 2 are mirror-symmetrical about the mirror plane. In this embodiment, the first direction can be a horizontal direction or a vertical direction. Preferably, when the lens 100 is installed on a vehicle, the first direction is a horizontal direction, the first light control part 1 and the second light control part 2 are relatively distributed on both sides of the lens 100 along a horizontal direction, and the structures of the first light control part 1 and the second light control part 2 are mirror-symmetrical, and the lens 100 can evenly project the light of the two low-beam light source parts to ensure that a uniform and symmetrical light spot can be formed on both sides of the lens 100.

[0039] In one embodiment, please refer to Figure 3 The first light-controlling portion 1 includes a first reflecting surface 11 and a second reflecting surface 12 which are arranged opposite to each other along a first direction. The first reflecting surface 11 is located on a side of the first light-controlling portion 1 close to the second light-controlling portion 2. The curvature radius of the first reflecting surface 11 is greater than the curvature radius of the second reflecting surface 12. The second light-controlling portion 2 includes a third reflecting surface 21 and a fourth reflecting surface 22 which are arranged opposite to each other along the first direction. The third reflecting surface 21 is located on a side of the second light-controlling portion 2 close to the first light-controlling portion 1. The curvature radius of the third reflecting surface 21 is greater than the curvature radius of the fourth reflecting surface 22.

[0040] In this embodiment, the first light control part 1 and the second light control part 2 can be arranged horizontally left and right or front and back. In a specific embodiment, the first light control part 1 and the second light control part 2 are arranged horizontally left and right, and the first reflecting surface 11 is located on the right side of the second reflecting surface 12. The light emitted to the right by the first low-beam light source 5 first irradiates the first reflecting surface 11, and the first reflecting surface 11 then emits the light to the left. The curvature radius of the first reflecting surface 11 is greater than the curvature radius of the second reflecting surface 12, so that after the light irradiates the first reflecting surface 11, it can form an exit light with a smaller reflection angle and exiting to the left on the first reflecting surface 11, so that when the exit light is emitted to the left, a wider light spot can be formed on the left side of the lens 100; At the same time, the third reflecting surface 21 is located on the left side of the fourth reflecting surface 22, and the light emitted to the left by the second low beam light source 6 first shines on the third reflecting surface 21, and the third reflecting surface 21 then emits the light to the right. The radius of curvature of the third reflecting surface 21 is greater than the radius of curvature of the fourth reflecting surface 22, so that after the light shines on the third reflecting surface 21, it can form an outgoing light with a smaller reflection angle and emitted to the right on the third reflecting surface 21, so that when the outgoing light is emitted to the right, a wider light spot can be formed on the right side of the lens 100; the mutual cooperation of the first light control part 1 and the second light control part 2 enables the lens 100 to obtain a wider light spot on both the left and right sides at the same time, thereby increasing the light spot width of the lamp in the horizontal direction and improving the lighting effect.

[0041] In one embodiment, please refer to Figure 4 The first light control part 1 also includes a fifth reflection surface 13 and a sixth reflection surface 14 which are arranged relatively to each other along a second direction. The second direction is perpendicular to both the central axis direction of the lens 100 and the first direction. The fifth reflection surface 13 and the sixth reflection surface 14 are used to direct the light of the first low-beam light source 5 toward the ground. The second light control part 2 also includes a seventh reflection surface (not shown in the figure) and an eighth reflection surface (not shown in the figure) which are arranged relatively to each other along the second direction. The seventh reflection surface and the eighth reflection surface are used to direct the light of the second low-beam light source 6 toward the ground.

[0042] In this embodiment, when the lens 100 is installed on the vehicle, the second direction is the vertical direction. When the light of the first low-beam light source 5 is irradiated onto the fifth reflecting surface 13 and the sixth reflecting surface 14, the light can form an outgoing light that is emitted downward on the fifth reflecting surface 13 and the sixth reflecting surface 14, so that the light can form a light spot on the ground, better illuminate the road surface, and ensure that the light will not directly irradiate the eyes of the driver of the oncoming vehicle, thereby avoiding the dazzling effect and improving the safety of night driving. Similarly, when the light of the second low-beam light source 6 is irradiated onto the seventh reflecting surface and the eighth reflecting surface, it can form an outgoing light that is emitted downward on the seventh reflecting surface and the eighth reflecting surface, so that the light can form a light spot on the ground.

[0043] In one embodiment, please refer to Figure 4 The first light-controlling part 1 also includes a first light-inlet cavity 15 and a first light-emitting surface 16, which are relatively arranged along the central axis direction of the first light-controlling part 1, and the first light-inlet cavity 15 includes a first polarized arc surface 151, and the first polarized arc surface 151 is used to direct the small-angle light of the first low-beam light source 5 toward the ground. The second light-controlling part 2 also includes a second light-inlet cavity 23 and a second light-emitting surface 24, which are relatively arranged along the central axis direction of the second light-controlling part 2, and the second light-inlet cavity 23 includes a second polarized arc surface 231, and the second polarized arc surface 231 is used to direct the small-angle light of the second low-beam light source 6 toward the ground.

[0044] In this embodiment, a portion of the large-angle light of the first low-beam light source 5 passes through the first light inlet cavity 15 and will be irradiated onto the fifth reflective surface 13 and the sixth reflective surface 14, and will be projected onto the ground by the fifth reflective surface 13 and the sixth reflective surface 14; a portion of the small-angle light of the first low-beam light source 5 passes through the first light inlet cavity 15 and will be irradiated onto the first polarized arc surface 151, and the first polarized arc surface 151 will direct the small-angle light of the first low-beam light source 5 toward the ground, which can further increase the brightness of the ground and improve the lighting effect. Similarly, a portion of the large-angle light of the second low-beam light source 6 passes through the second light inlet cavity 23 and will be irradiated onto the seventh reflective surface and the eighth reflective surface, and will be projected onto the ground by the seventh reflective surface and the eighth reflective surface; a portion of the small-angle light of the second low-beam light source 6 passes through the second light inlet cavity 23 and will be irradiated onto the second polarized arc surface 231, and the second polarized arc surface 231 will direct the small-angle light of the second low-beam light source 6 toward the ground, which can further increase the brightness of the ground.

[0045] For further information, please refer to Figure 4The first light inlet cavity 15 also includes a first side wall 152 and a first light inlet port 153. The first side wall 152 is arranged around the periphery of the first polarizing arc surface 151. The first light inlet port 153 and the first polarizing arc surface 151 are arranged relatively to each other along the central axis direction of the first light control portion 1. The second light inlet cavity 23 also includes a second side wall 232 and a second light inlet port 233. The second side wall 232 is arranged around the periphery of the second polarizing arc surface 231. The second light inlet port 233 and the second polarizing arc surface 231 are arranged relatively to each other along the central axis direction of the second light control portion 2. In this embodiment, the first reflection surface 11, the second reflection surface 12, the fifth reflection surface 13 and the sixth reflection surface 14 are all arranged on the periphery of the first light inlet cavity 15, and the first side wall 152 is used to refract the light in the first light inlet cavity 15. After the light in the first light inlet cavity 15 is refracted by the first side wall 152, it will be irradiated onto the first reflection surface 11, the second reflection surface 12, the fifth reflection surface 13 and / or the sixth reflection surface 14; similarly, the third reflection surface 21, the fourth reflection surface 22, the seventh reflection surface and the eighth reflection surface are all arranged on the periphery of the second light inlet cavity 23, and the second side wall 232 is used to refract the light in the second light inlet cavity 23. After the light in the second light inlet cavity 23 is refracted by the second side wall 232, it will be irradiated onto the third reflection surface 21, the fourth reflection surface 22, the seventh reflection surface and / or the eighth reflection surface.

[0046] In this embodiment, the light of the first low-beam light source 5 enters the first light inlet cavity 15 from the first light inlet port 153, and the light is emitted from the first light exit surface 16 after being refracted and reflected by the first light inlet cavity 15, the first reflection surface 11, the second reflection surface 12, the fifth reflection surface 13 and the sixth reflection surface 14; the light of the second low-beam light source 6 enters the second light inlet cavity 23 from the second light inlet port 233, and the light is emitted from the second light exit surface 24 after being refracted and reflected by the second light inlet cavity 23, the third reflection surface 21, the fourth reflection surface 22, the seventh reflection surface and the eighth reflection surface. The shapes of the first light exit surface 16 and the second light exit surface 24 are not limited, and the first light exit surface 16 and the second light exit surface 24 can be concave, convex or flat. In a preferred embodiment, the first light exit surface 16 and the second light exit surface 24 are flat. Compared with the wavy light exit surface used in the traditional low-beam light, the flat light exit surface is simpler and more convenient to process, and the light exit surface is flat and not easy to generate glare. In another preferred embodiment, the first light emitting surface 16 and the second light emitting surface 24 are located on the same plane.

[0047] In one embodiment, please refer to Figure 5The third light control portion 3 includes a third light inlet 31 and a third light outlet surface 32, and the third light inlet 31 and the third light outlet surface 32 are arranged relatively to each other along the central axis direction of the third light control portion 3. The third light outlet surface 32 includes a first arc surface 321 and a second arc surface 322 arranged around the outer periphery of the first arc surface 321. The first arc surface 321 is arched in the direction away from the third light inlet, and the second arc surface 322 is concave in the direction close to the third light inlet. Specifically, the light of the high beam light source 7 is incident from the third light inlet 31 and emitted from the third light emitting surface 32. The light intensity of the high beam light source 7 is generally strong, which is easy to cause glare when it hits the human eye. The third light emitting surface 32 includes a first curved surface 321 and a second curved surface 322 arranged around the outer periphery of the first curved surface 321, and the first curved surface 321 is arched in the direction away from the third light inlet, and the second curved surface 322 is concave in the direction close to the third light inlet. When the human eye looks at the third light emitting surface 32 from the side of the third light emitting surface 32, the first curved surface 321 and the second curved surface 322 of the downhill section will be blocked, thereby reducing the visible area of ​​the third light emitting surface 32 and reducing the glare caused by the third light emitting surface 32 to the human eye.

[0048] Furthermore, the first light-controlling part 1 , the second light-controlling part 2 and the third light-controlling part 3 are integrally formed. The integrally formed design can save the assembly process between the first light-controlling part 1 , the second light-controlling part 2 and the third light-controlling part 3 , and the structure of the lens 100 is more stable.

[0049] In one embodiment, please refer to Figure 2 , a microstructure 33 is provided on the outer wall of the first light control part 1, the second light control part 2 and / or the third light control part 3. The microstructure 33 can make the light emit more uniformly and reduce glare. In this embodiment, the shape, number and arrangement of the microstructure 33 are not limited. The shape of the microstructure 33 can be spherical, conical, polygonal, concave, convex or other shapes. The arrangement of the microstructure 33 is not limited, and can be a Thiessen polygon arrangement, a golden spiral arrangement, a ring array, an irregular arrangement or other arrangements.

[0052] In this embodiment, the lamp integrates the first light-controlling part 1 , the second light-controlling part 2 and the third light-controlling part 3 on the same lens 100 , thereby saving the number of lenses 100 , simplifying the lamp structure and reducing the occupied space of the lamp.
