Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0032] The optical module, headlights, and vehicle described in this application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0033] In existing technologies, to solve the problem of gaps at the overlap of adjacent unit lights, the following methods are often used: Figure 1 The structure shown uses overlapping protrusions 81 on the side to cover the gap between adjacent unit lights 80. However, when viewed from the front, this structure has a ghosting effect, unclear dividing boundaries, uneven side gaps, and poor visual effect. Furthermore, when injection molding, a core-pulling structure needs to be added, which increases the cost of mold making.
[0034] To address the aforementioned technical problems, this application provides an optical module including a first light-distributing lens and a second light-distributing lens arranged side-by-side. The main light-emitting direction of the first light-distributing lens is parallel to the main light-emitting direction of the second light-distributing lens. The first light-distributing lens has a first splicing surface on its side facing the second light-distributing lens, and this first splicing surface is connected to the light-emitting surface of the first light-distributing lens. The second light-distributing lens has a second splicing surface on its side facing the first light-distributing lens, and this second splicing surface is connected to the light-emitting surface of the second light-distributing lens. The first splicing surface is parallel to the second splicing surface, and both the first and second splicing surfaces are parallel to the main light-emitting direction of the first light-distributing lens. This will be described in detail below.
[0035] See Figures 2-4 The optical module includes a first light distribution lens 10 and a second light distribution lens 20 arranged side by side. The main light output direction of the first light distribution lens 10 is parallel to the main light output direction of the second light distribution lens 20. The first light distribution lens 10 has a first splicing surface 111 on the side facing the second light distribution lens 20, and the first splicing surface 111 is connected to the light output surface of the first light distribution lens 10. The second light distribution lens 20 has a second splicing surface 211 on the side facing the first light distribution lens 10, and the second splicing surface 211 is connected to the light output surface of the second light distribution lens 20. The first splicing surface 111 is parallel to the second splicing surface 211, and both the first splicing surface 111 and the second splicing surface 211 are parallel to the main light output direction of the first light distribution lens 10.
[0036] The main light-emitting direction of the first light distribution lens 10 is parallel to the main light-emitting direction of the second light distribution lens 20, that is, the main light-emitting directions of the first light distribution lens 10 and the second light distribution lens 20 are the same, and for the convenience of description, the main light-emitting direction is denoted as the first direction (as indicated by the middle direction X, the same below). Figures 3-4
[0037] By parallelizing the first splicing surface 111 and the second splicing surface 211, the spacing between the first light distribution lens 10 and the second light distribution lens 20 can be controlled in a small range when the first light distribution lens 10 and the second light distribution lens 20 are spliced and assembled, compared with the setting of the lap convex block 81 in the prior art, the appearance boundary of the present application is clearer, and the structural ghosting is effectively avoided, and the first light distribution lens 10 and the second light distribution lens 20 are more naturally connected.
[0038] Meanwhile, the first splicing surface 111 and the second splicing surface 211 are parallel to the first direction, and after the optical module is turned on, the first splicing surface 111 and the second splicing surface 211 will not affect the propagation of light, the whole is more coherent, and the visual effect is good.
[0039] It is worth mentioning that, compared with the prior art, the present application omits the setting of the lap convex block 81, which is conducive to simplifying the structure of the mold, reducing the design amount, shortening the mold development period, and reducing the production cost.
[0040] It should be noted that the first splicing surface 111 and the second splicing surface 211 are oppositely arranged, and in order to ensure the consistency of the overall appearance of the optical module, the light-emitting surface of the first light distribution lens 10 and the light-emitting surface of the second light distribution lens 20 are arranged substantially coplanar, and the appearance consistency of the optical module is good.
[0041] The two light-emitting surfaces (the light-emitting surface of the first light distribution lens 10 and the light-emitting surface of the second light distribution lens 20, the same below) can be arranged as a plane or a curved surface, when arranged as a plane, the two light-emitting surfaces are arranged substantially coplanar, which can be that the two light-emitting surfaces are completely coincident, or there is a slight error in the first direction due to size error and other reasons; when the two light-emitting surfaces are arranged as curved surfaces, the two curved surfaces can be connected into a smooth curved surface, the appearance consistency is good, and the first light distribution lens 10 and the second light distribution lens 20 are more naturally connected.
[0042] In some embodiments, the first light distribution lens 10 is provided with a first splicing portion 11 on the side facing the second light distribution lens 20, the first splicing portion 11 has a first splicing surface 111 on the side close to the second light distribution lens 20, and the first splicing portion 11 is configured to guide the light on the light-incident side of the first light distribution lens 10 to be emitted towards the second light distribution lens 20; and / or, the second light distribution lens 20 is provided with a second splicing portion 21 on the side facing the first light distribution lens 10, the second splicing portion 21 has a second splicing surface 211 on the side close to the first light distribution lens 10, and the second splicing portion 21 is configured to guide the light on the light-incident side of the second light distribution lens 20 to be emitted towards the first light distribution lens 10.
[0043] The first splicing section 11 is configured to guide the light from the light-incident side of the first optical lens 10 toward the second optical lens 20. That is, the first splicing section 11 does not block the light; the light can pass through it. The light transmitted from the first splicing section 11 can compensate for the gap 30 between the first optical lens 10 and the second optical lens 20. When the optical module is lit, there is no abruptness between the first optical lens 10 and the second optical lens 20 (no obvious dark area), resulting in a more coherent overall appearance and better visual effect. The second splicing section 21 is similar to the first splicing section 11 and will not be described further here.
[0044] In some embodiments, both the first splicing part 11 and the second splicing part 21 are light-transmitting, and the gap 30 between the first light distribution lens 10 and the second light distribution lens 20 is compensated on both sides, resulting in a better visual effect.
[0045] The first light distribution lens 10 is also provided with a first mounting part 12, which is connected to the side of the first splicing part 11 away from the light-emitting surface of the first light distribution lens 10; a projection surface λ is set perpendicular to the main light-emitting direction of the first light distribution lens 10, and the orthographic projection of the first mounting part 12 on the projection surface λ overlaps with the orthographic projection of the second splicing part 21 on the projection surface λ.
[0046] The orthographic projections of the first mounting part 12 and the second splicing part 21 on the projection plane λ overlap, that is, the first mounting part 12 is located to the left of the first splicing part 11. Figure 3 (View angle, the same below) The first mounting part 12 and the first splicing part 11 are arranged laterally offset, and the first mounting part 12 can block the bottom of the gap 30 (the gap 30 between the first light distribution lens 10 and the second light distribution lens 20, the same below). When viewed from the light-emitting side of the optical module, the internal mounting structure cannot be observed through the gap 30, resulting in a good visual effect.
[0047] In some embodiments, the optical module further includes a second mounting bracket 50, which is connected to the end of the second splicing portion 21 away from the light-emitting surface of the second light distribution lens 20, and the second mounting bracket 50 is disposed opposite to the first mounting portion 12; the orthographic projection of the second mounting bracket 50 on the projection surface λ is located on the side of the orthographic projection of the second splicing portion 21 on the projection surface λ away from the first splicing portion 11.
[0048] That is, the second mounting bracket 50 is offset to the left side of the second splicing part 21. Figure 3The second mounting frame 50 is arranged laterally offset from the second splicing portion 21, i.e., the second mounting frame 50 is offset to the left, so that the mounting space provided by the first mounting portion 12 can be as large as possible, and the first splicing surface 111 can be as close as possible to the second splicing surface 211 when the first light distribution lens 10 and the second light distribution lens 20 are assembled, i.e., the gap 30 between the first light distribution lens 10 and the second light distribution lens 20 is reduced, and the first light distribution lens 10 and the second light distribution lens 20 are connected more naturally, thereby improving the visual effect.
[0049] In some embodiments, the optical module further comprises a first light guide component 60 and a second light guide component 70, the first light guide component 60 is configured to adjust light and emit the adjusted light to the first light distribution lens 10, and the second light guide component 70 is configured to adjust light and emit the adjusted light to the second light distribution lens 20. Through the arrangement of the mounting position of the second mounting frame 50 on the second splicing portion 21, the first light guide component 60 can be closer to the second light guide component 70 (i.e., the lateral distance between the first light guide component 60 and the second light guide component 70 is reduced), so that the overall visual effect is more coherent when the optical module is lit.
[0050] It is worth mentioning that when the second mounting frame 50 is arranged on the side of the second splicing portion 21 away from the first splicing portion 11, the second mounting frame 50 occupies the lateral internal space of the second light distribution lens 20, i.e., the second mounting frame 50 is connected to the end of the second splicing portion 21 and does not occupy the lateral internal space of the second light distribution lens 20, which is beneficial to the arrangement of the remaining components.
[0051] In some embodiments, the surface of the first mounting portion 12 facing the second mounting frame 50 is a first surface 121, and the surface of the second mounting frame 50 facing the first mounting portion 12 is a second surface 51; the first surface 121 is parallel to the second surface 51.
[0052] The first surface 121 is parallel to the second surface 51, which is beneficial to the first mounting portion 12 being closer to the second mounting frame 50, and thus the first splicing surface 111 is closer to the second splicing surface 211, the first light distribution lens 10 and the second light distribution lens 20 are connected more naturally, and the visual effect is improved.
[0053] In some embodiments, the first surface 121 is parallel to the first splicing surface 111.
[0054] When the first surface 121 is not parallel to the first splicing surface 111, i.e., the first surface 121 intersects the first direction, the first mounting portion 12 occupies more lateral space, which is not conducive to the arrangement of the remaining components; when the first surface 121 is parallel to the first splicing surface 111, i.e., the first surface 121, the second surface 51, the first splicing surface 111, and the second splicing surface 211 are all parallel to each other, the lateral dimension of the first mounting portion 12 is only the thickness of the first mounting portion 12, which is beneficial to reducing the occupation of lateral space.
[0055] In some embodiments, the optical module further comprises a first mounting frame 40 connected to the first mounting portion 12 on a side away from the second mounting frame 50.
[0056] In this embodiment, the first mounting frame 40 is arranged on the side of the first mounting portion 12 away from the second mounting frame 50, i.e. the first mounting frame 40 does not occupy the space between the first mounting portion 12 and the second mounting frame 50, so that the first mounting portion 12 can be closer to the second mounting frame 50, i.e. the first splicing surface 111 is closer to the second splicing surface 211, the first light distribution lens 10 and the second light distribution lens 20 are more naturally connected, and the visual effect is improved.
[0057] In some embodiments, the optical module further comprises a first light guide component 60 and a second light guide component 70, the first light guide component 60 is arranged on the light entrance side of the first light distribution lens 10, and the second light guide component 70 is arranged on the light entrance side of the second light distribution lens 20; the distance between the first light guide component 60 and the second light guide component 70 in the second direction is d, which satisfies: 10mm≤d≤21mm, and the second direction is perpendicular to the first splicing surface 111.
[0058] When the value of d is greater than 21mm, the distance between the first light guide component 60 and the second light guide component 70 is large, and when the optical module is turned on, the first light distribution lens 10 and the second light distribution lens 20 are prone to appear dark area at the splicing position, and the overall visual effect is poor; when the value of d is less than 10mm, the light at the adjacent position of the first light guide component 60 and the second light guide component 70 will interfere with each other, the visual effect is poor, and the smaller the distance between the first light guide component 60 and the second light guide component 70, the more difficult the processing of the remaining components will be, and the production cost will be increased.
[0059] It should be noted that the second direction is indicated by direction Y in the figure.
[0060] On the other hand, the present application also relates to a vehicle lamp comprising any one of the aforementioned optical modules.
[0061] On the other hand, the present application also relates to a vehicle comprising the aforementioned vehicle lamp.
[0062] By adopting the technical scheme provided in the embodiments of the present application, the interval between the first light distribution lens 10 and the second light distribution lens 20 can be controlled in a smaller range when the first light distribution lens 10 and the second light distribution lens 20 are spliced and assembled, the appearance boundary is clearer, the structural ghosting is effectively avoided, and the first light distribution lens 10 and the second light distribution lens 20 are more naturally connected compared with the setting of the lap joint protrusion 81 in the prior art. Meanwhile, the first splicing surface 111 and the second splicing surface 211 are parallel to the first direction, and the first splicing surface 111 and the second splicing surface 211 will not affect the propagation of light after the optical module is lighted, the whole is more coherent, and the visual effect is good.
