[0036] The present application will be described in detail below with reference to the drawings and specific embodiments.

[0037] In the prior art, the lamp design is more and more personalized and diversified, so that the lamp modeling is complex, and the light exit surface of the lamp is also complex in modeling. When the lamp is actually lighted, dark areas are easily generated, the overall lighting uniformity is poor, and the lamp quality is reduced.

By locally arranging the light adjusting structure, the part of the light rays collimated by the light collecting part are gradually directed to the dark area of the corner of the second light exit surface, the lighting brightness of the dark area of the second light exit surface can be ensured, the dark area of the second light exit surface is avoided, and the uniformity of the lighting is effectively improved; the adjustment path designed in the present application is more accurate for adjusting the light rays, the light rays can be effectively and accurately refracted to the dark area of the second light exit surface, and the light rays are avoided from being directed to the non-dark area to cause light waste or the local light rays to be too strong to form bright spots. The details are described below.

[0039] Referring to Figures 1-4 , the optical module comprises a first light guide component 10 and a second light guide component 20; the first light guide component 10 comprises a light collecting part 11 and a main body part 12, the main body part 12 has a first light exit surface 121 on the side away from the light collecting part 11, light rays collimated by the light collecting part 11 are directed to the first light exit surface 121 and exit through the first light exit surface 121; at least one first refractive surface 122 is arranged at the corner of the first light exit surface 121, the first refractive surface 122 is configured to receive the light rays exiting through the first light exit surface 121 and deflect the light rays towards the peripheral side of the first light exit surface 121; the second light guide component 20 has a second light entrance surface 21 and a second light exit surface 22 arranged oppositely, the second light entrance surface 21 is arranged oppositely spaced apart from the first light exit surface 121; a second refractive surface 23 is arranged at the corner of the second light entrance surface 21, the second refractive surface 23 corresponds to the first refractive surface 122 one by one, and the second refractive surface 23 is configured to receive the light rays refracted by the first refractive surface 122 and deflect the light rays towards the peripheral side of the second light entrance surface 21, the deflected light rays are transmitted in the second light guide component 20 and directed to the area of the second light exit surface 22 and the second refractive surface 23.

[0040] For ease of illustration, in the following embodiments, the first refractive surface 122 and the second refractive surface 23 are taken as an example to be triangularly arranged for discussion. In some embodiments, the first refractive surface 122 can also be quadrangular, and the like, and is not limited thereto. The shape of the first refractive surface 122 can be freely determined according to the need to supplement the light rays, and can also be curved. In addition, the first refractive surface 122 and the second refractive surface 23 are taken as an example to be arranged at the corners of the first light exit surface 121 and the second light entrance surface 21 for discussion. In some embodiments, the first refractive surface 122 can also be arranged at the edges of the first light exit surface 121, and the second refractive surface 23 can also be arranged at the edges of the second light entrance surface 21, and is not limited thereto. The first refractive surface 122 and the second refractive surface 23 can be arranged according to the dark area that appears when the vehicle lamp is lit, to ensure the uniformity of the final lighting.

[0041] As shown in FIG. 1, the light rays emitted by the light source 10 are incident on the first light entrance surface 21 of the light guide 20, and are refracted by the first refractive surface 122 to be parallel to the first light exit surface 121. Figure 4 As shown in FIG. 1, the light rays emitted by the light source 10 are incident on the first light entrance surface 21 of the light guide 20, and are refracted by the first refractive surface 122 to be parallel to the first light exit surface 121. Figure 4 As shown in FIG. 1, the light rays emitted by the light source 10 are incident on the first light entrance surface 21 of the light guide 20, and are refracted by the first refractive surface 122 to be parallel to the first light exit surface 121.

[0042] Through the cooperation of the first refractive surface 122 and the second refractive surface 23, the light rays collimated by the light collecting portion 11 are gradually emitted to the corners of the second light exit surface 22, which can ensure the lighting brightness of the corners of the second light exit surface 22, avoid the formation of dark areas in the corners of the second light exit surface 22, and effectively improve the uniformity of the lighting. At the same time, the two-time adjustment is more accurate for the adjustment of the light rays, which can effectively and accurately refract the light rays to the corners of the second light exit surface 22, and avoid the waste of light rays or the formation of bright spots due to the emission of light rays to non-corners.

[0043] It is worth mentioning that the light rays finally shoot from the corner of the first light exit surface 121 to the corner of the second light exit surface 22, and the light rays overall expand outward, that is, the overall light exit range of the second light exit surface 22 is larger than that of the first light exit surface 121, that is, the first light guide component 10 occupies a smaller volume (which is beneficial to the miniaturization of the internal optical element). In actual application, more assembly space can be provided for the inside of the lamp body, and more layout space can be provided for the remaining parts; at the same time, the first light guide component 10 has a smaller volume, which saves production materials and production costs, and is beneficial to the lightweight design of the vehicle lamp; in addition, the larger area of the second light exit surface 22 can improve the lighting range and improve the lighting effect of the vehicle lamp; under the premise of the same size of the second light exit surface 22, the first light guide component 10 with a smaller volume can meet the light distribution requirements.

[0044] It should be noted that in the embodiment, the corner of the first light exit surface 121 is the corner formed by the adjacent two edges of the first light exit surface 121, which is triangularly arranged; correspondingly, in the actual product, the first refractive surface 122 and the first light guide component 10 can be integrally arranged, that is, a triangular prism is arranged on the first light exit surface 121 of the first light guide component 10, one face of the triangular prism is attached to the first light exit surface 121, the other two faces are coplanar with the first light guide component 10 around the peripheral wall of the first light exit surface 121, and the remaining one face is the first refractive surface 122. Integrally arranged is beneficial to molding and improves production efficiency; the corners of the second light exit surface 21 and the second refractive surface 23 are similar, which will not be described here.

[0045] In actual application, multiple corners of the first light exit surface 121 (the second light exit surface 21 is adapted to the first light exit surface 121, and the first light exit surface 121 is taken as an example for discussion) can be arranged according to the shape of the first light exit surface 121; for example, in the vehicle logo lamp, the first light exit surface 121 can be in the shape of a letter, and through the arrangement of the first refractive surface 122 and the second refractive surface 23, the uniformity of the logo lamp lighting can be improved, and the lighting effect and recognition can be improved.

[0046] In addition, it should be noted that in order to ensure the uniformity of the final lighting, the second light guide component 20 can be arranged in a milky white color, which is beneficial to light diffusion and improves uniformity, and is not limited to this. In some embodiments, it can also be in other ways, such as arranging diffusion patterns on the second light exit surface 22; the second refractive surface 23 corresponds to the first refractive surface 122 one by one, that is, the first refractive surface 122 at the same side corner of the first light exit surface 121 corresponds to the second refractive surface 23 at the same side corner of the second light exit surface 21, and at the same time corresponds to the second light exit surface 22 at the same side corner.

[0047] In some embodiments, the first refractive surface 122 and the second refractive surface 23 are arranged in a planar manner; the light rays incident on the first refractive surface 122 are arranged at an acute angle with the first refractive surface 122, and the light rays refracted by the first refractive surface 122 and incident on the second refractive surface 23 are arranged at an acute angle with the second refractive surface 23.

[0048] like Figure 4 As shown, the angle between the ray incident on the first refractive surface 122 and the first refractive surface 122 is α, where α is an acute angle. That is, the normal a of the first refractive surface 122 (i.e., the straight line perpendicular to the first refractive surface 122) is located below the ray incident on the first refractive surface 122. According to the law of refraction, the ray L1 after being refracted by the first refractive surface 122 is located below the normal a, that is, the ray is refracted to the lower left. The angle between the ray L1 (i.e., the ray refracted by the first refractive surface 122 and incident on the second refractive surface 23) and the second refractive surface 23 is β, where β is an acute angle. That is, the normal b of the second refractive surface 23 (i.e., the straight line perpendicular to the second refractive surface 23) is located above the ray L1. According to the law of refraction, the ray L2 after being refracted by the second refractive surface 23 is located above the normal b, that is, the ray is refracted to the lower left.

[0049] In this process, light ray L1 is formed from inside the first light guide component 10 and directed towards the air, while light ray L2 is formed from the air and directed towards the inside of the second light guide component 20. The refraction angles of light rays L1 and L2 are different (light ray L1 is deflected towards the side away from the normal a, while light ray L2 is deflected towards the side closer to the normal b). That is, the angle between light ray L2 and the X-axis direction (parallel to the main light output direction of the optical module, which in practical applications can be the front and rear direction of the vehicle) is smaller than the angle between light ray L1 and the X-axis direction. In other words, after the light passes through the second refraction surface 23, the outward expansion angle of the light is reduced, and the light tends to be parallel to the X-axis direction. The light has strong penetrating power and can travel a longer distance. During the propagation process, the energy attenuation is relatively slow, and the area covered by the light can provide high brightness, which is beneficial to improving the visibility of the vehicle lights.

[0050] To facilitate understanding, the following counterexamples are provided: Figure 6 As shown, the angle between ray L1' and the second refractive surface 23 is δ, which is an obtuse angle. This means the normal b' of the second refractive surface 23 is below ray L1'. According to the law of refraction, ray L2', after being refracted by the second refractive surface 23, is below the normal b' (ray L2' is deflected towards the side closer to the normal b'). Compared to ray L2 in the previous embodiment, ray L2' has a larger angle with the X-axis, and its outward expansion angle is greater, which is not conducive to long-distance propagation of light. Of course, the obtuse angle between ray L1' and the second refractive surface 23 also falls within the protection scope of this application, and related designs can be made according to the lighting requirements and shape of the vehicle headlights.

[0051] In some embodiments, the included angle γ between the first refracting surface 122 and the second refracting surface 23 satisfies: 30°≤γ≤60°, for example, 30°, 40°, 50°, 60°, etc.

[0052] When the value of γ is less than 30°, the light rays incident on the second refractive surface 23 may undergo total internal reflection, which is not conducive to the refraction of light. When the value of γ is greater than 60°, the light rays incident on the second refractive surface 23 are set at an obtuse angle with the refractive surface, and the second refractive surface 23 cannot present the effect expected in this application. For detailed analysis, please refer to the aforementioned embodiments, which will not be repeated here.

[0053] In some embodiments, the second refracting surface 23 is disposed at the corner of the second incident surface 21, and a third refracting surface 24 is also provided on the second refracting surface 23, with the third refracting surface 24 located on the side of the second refracting surface 23 away from the corner of the second incident surface 21 (i.e., as shown in the figure). Figure 4 As shown, the third refractive surface 24 is disposed to the right of the second refractive surface 23; the third refractive surface 24 is configured to receive light rays refracted by the first refractive surface 122 and deflect the light rays toward the periphery of the second incident surface 21; the angle between the second refractive surface 23 and the second incident surface 21 is smaller than the angle between the third refractive surface 24 and the second incident surface 21.

[0054] In this embodiment, a third refractive surface 24 is provided on the second refractive surface 23, and the angle between the second refractive surface 23 and the second incident surface 21 is smaller than the angle between the third refractive surface 24 and the second incident surface 21. With this arrangement, the light rays incident on the third refractive surface 24 are deflected at a larger angle (the angle between the light rays and the X-axis direction is greater than the angle between the light rays refracted by the second refractive surface 23 and the X-axis direction). At the same time, since the third refractive surface 24 is located on the side of the second refractive surface 23 away from the corner of the second incident surface 21, the light rays are further converged towards the corner of the second emitting surface 22 through the third refractive surface 24. The light rays that were originally incident on the second refractive surface 23 away from the corner of the second incident surface 21 are deflected and brought closer to the corner, and finally emitted from the corner of the second emitting surface 22, which improves the brightness of the corner and is beneficial to the overall uniformity.

[0055] To make the above description clearer, please refer to Figure 5 Comparison illustration: In this application, the light refracted by the first refractive surface 122 is directed towards the second refractive surface 23. When the second refractive surface 23 is not provided with a third refractive surface 24 (e.g. Figure 5As shown in FIG. 6, the second refractive surface 23 is closer to the center region of the second light-incident surface 21 at the position away from the corner, and the light brightness at the position is higher than that at the corner, so that the corner is relatively dark. However, in the present application, the third refractive surface 24 is arranged to refract the light at the position with relatively high brightness (the position of the second refractive surface 23 away from the corner) toward the side close to the corner, so as to reduce the brightness at the position with relatively high brightness and increase the brightness at the corner of the second light-emitting surface 22, thereby making the overall brightness uniform and improving the uniformity of the overall lighting.

[0056] It is worth mentioning that the third refractive surface 24 can be set according to the actual lighting condition, and the light can be adjusted to the dark area through the third refractive surface 24 to achieve the uniformity of lighting.

[0057] Referring to Figures 10-12 , the second refractive surface 23 is triangularly arranged, and one of the angles of the triangle is arranged at the corner of the second light-incident surface 21; the third refractive surface 24 is provided with two, and the two third refractive surfaces 24 are respectively arranged at the other two angles of the triangle of the second refractive surface 23, and the two third refractive surfaces 24 are arranged at an angle, and the third refractive surface 24 is configured to receive the light refracted by the first refractive surface 122 and emit the light toward the corner of the second light-emitting surface 22.

[0058] In the present embodiment, the third refractive surface 24 is provided with two, and the two third refractive surfaces 24 are arranged at an angle, so that the light adjusted by the two third refractive surfaces 24 is emitted toward the corner (the corner corresponding to the third refractive surface 24) of the second light-emitting surface 22, and the light can be more concentrated to improve the brightness of the corner of the second light-emitting surface 22; at the same time, the two third refractive surfaces 24 are arranged at the positions of the other two angles of the triangle of the second refractive surface 23, and in the present embodiment, the third refractive surface 24 can refract the light originally emitted toward the edge of the second refractive surface 23 to form a bright spot toward the corner of the second light-emitting surface 22 (when the light is emitted toward the second refractive surface 23, part of the light is deflected toward the edge of the second refractive surface 23 to form a bright spot, and in the present embodiment, the part of the light is refracted toward the corner of the second light-emitting surface 22 through the third refractive surface 24, which solves the problem of bright spot and improves the uniformity of the overall lighting.

[0059] It is worth mentioning that in the present embodiment, the third refractive surface 24 is also triangularly arranged, and the specific arrangement form is shown in Figure 11 , and the third refractive surface 24 can adjust the light emitted toward the edge of the second refractive surface 23 to be emitted toward the corner of the second light-emitting surface 22.

[0060] In some embodiments, the shape of the second refractive surface 23 can also be other designs, such as quadrilateral, etc., and the shape, number, specific arrangement position, etc. of the third refractive surface 24 are not limited to this, and the light can be adjusted to the dark area by the third refractive surface 24 to achieve the uniformity of the lighting, which will not be described here.

[0061] Referring to Figures 7-8 , the edge of the first light exit surface 121 is further provided with a fourth refractive surface 123, which is configured to receive the light emitted by the first light exit surface 121 and deflect the light towards the inside of the periphery of the first light exit surface 121.

[0062] In actual lighting, part of the light is deflected to the edge to form a bright spot, so the fourth refractive surface 123 is arranged on the edge of the first light exit surface 121 to deflect the part of the light towards the inside of the periphery of the first light exit surface 121 (opposite to the deflection direction of the first refractive surface 122, the light expands outward after being deflected by the first refractive surface 122, and the light is inward after being deflected by the fourth refractive surface 123), which weakens the bright spot on the ridge and is beneficial to the improvement of the overall uniformity.

[0063] It is worth mentioning that in some embodiments, the second light entrance surface 21 can also be provided with a refractive structure similar to the fourth refractive surface 123, which can adjust the light in the high brightness area to the low brightness area to achieve the uniformity of the lighting, which will not be described here.

[0064] Referring to Figure 2 , Figure 3 and Figure 9 , the first light guide component 10 further comprises a reinforcing part 13, and the reinforcing part 13 has a reflecting surface 131 arranged on the periphery of the light collecting part 11; the reflecting surface 131 is configured to receive the light emitted by the light source 40 and reflect the light to the corresponding area of the first refractive surface 122.

[0065] The reflecting surface 131 of the reinforcing part 13 is arranged on the periphery of the light collecting part 11, which can receive part of the light emitted by the light source 40 (when the reflecting surface 131 is not arranged, the part of the light here is not utilized, which is stray light) and reflect it to the corresponding area of the first refractive surface 122, so as to fully utilize the light and avoid waste of light; and by reflecting the light to the corresponding area of the first refractive surface 122 (the corresponding area is the area where the dark area is prone to appear during lighting), the luminous flux of the corresponding area of the first refractive surface 122 can be improved, i.e. the brightness is improved, the dark area is weakened, and the overall uniformity of the lighting is improved; both stray light and the uniformity of the lighting are improved.

[0066] It is worth mentioning that the first refractive surface 122 is arranged to refract and expand the collimated light rays outwardly to the corner of the second light-incident surface 21 (taking the corner as an example for discussion), and in this application, the originally wasted light rays can be reused by arranging the reflecting surface 131, and the vacancy caused by the refraction of the light rays by the first refractive surface 122 can be supplemented, which is beneficial to improve the uniformity of overall lighting.

[0067] It should be noted that in actual product embodiments, the reflecting surface 131 can be a part of the collimating surface 111 of the light collecting portion 11, and the reflecting structure can be arranged on the part of the collimating surface 111 to achieve light reflection. The reflection angle of the light rays can be designed according to actual use requirements to reflect the light rays to the area that needs to be reinforced. For example Figure 3 In the embodiment shown, the main optical axis of the light source 40 extends horizontally left and right, the reflecting surface 131 is arranged on the upper left side of the main optical axis (upper left), and the first refractive surface 122 is arranged on the lower right side of the main optical axis (lower right), that is, the reflecting surface 131 and the first refractive surface 122 are diagonally arranged.

[0068] In addition, in actual products, the first light guide component 10 is provided with a mounting portion 14 (for assembly of the first light guide component 10), as shown in Figure 3 The mounting portion 14 is arranged at the middle (lateral middle) position of the main body portion 12, and when the reflecting surface 131 and the first refractive surface 122 are diagonally arranged, the reinforcing portion 13 only needs to be integrally arranged with the light collecting portion 11 on the left side of the mounting portion 14 to achieve the propagation of the reflected light rays by the reflecting surface 131. The reinforcing portion 13 does not need to extend to the right side of the mounting portion 14, which reduces the volume occupation on the right side of the main body portion 12 and reduces the overall weight.

[0069] In some embodiments, the first light guide component 10 is arranged in a shape, for example, in an A shape, which will have an acute angle corner (as shown by reference numerals B, C, and D). Figure 2 The acute angle corner is more prone to dark areas (of course, in some embodiments, dark areas also exist in non-acute angles, which are also within the protection scope of this application), and the related reflecting surface 131 is arranged at the diagonal position of the corner (for details of "diagonal", see the foregoing analysis), which can reflect the light rays to the corner prone to dark areas, improve the uniformity of overall lighting, and at the same time, the edge of the reflecting surface 131 can be correspondingly arranged with the edge of the corner (the outer contours are adapted to each other), so that the light rays reflected by the reflecting surface 131 can be well adapted to the corner, avoiding the situation that the reflected light rays cannot completely cover the corner or exceed the corner range to form stray light, etc.

[0070] In addition, the light emitted by the light source 40 is fully applied to the dark area by the reflection surface 131 integrated with the light collecting part 11, and no additional light source is needed to provide brightness for the dark area, thereby reducing the cost of adding a light source and avoiding the problem of high temperature caused by adding a light source, which may cause ablation of the first light guide component 10, and reducing the use cost.

[0071] In some embodiments, the angle between the first refractive surface 122 and the first light exit surface 121 is θ, and satisfies: 30°≤θ≤45°.

[0072] When the value of θ is less than 30°, the refraction angle (the angle between the refracted light and the X-axis direction) of the light after being refracted by the first refractive surface 122 is large, which is not conducive to the propagation of the light in the X-axis direction, and the large refraction angle may cause the light to be easily directed to the support 30 in the actual product, and the light cannot be directed to the second light entrance surface 21, thereby reducing the light utilization rate; when the value of θ is greater than 45°, the refraction angle of the light after being refracted by the first refractive surface 122 is small, which is not conducive to adjusting the light to the corner of the second light guide component 20 (the corner of the second light exit surface 22), and is not conducive to improving the overall lighting uniformity.

[0073] In some embodiments, the optical module further comprises a support 30, the support 30 is provided with a containing through hole 31, the first light exit surface 121 is adapted and contained in the containing through hole 31, and the second light guide component 20 is arranged on the side of the containing through hole 31 away from the first light guide component 10.

[0074] In the embodiment, the first light exit surface 121 is arranged in the containing through hole 31 to avoid stray light; in the actual product, the second light guide component 20 and the support 30 can be integrally formed by two-color injection molding, which is convenient to process, and can avoid the gap between the second light guide component 20 and the support 30, thereby improving the overall visual effect.

[0075] On the other hand, the present application also relates to a vehicle comprising any one of the optical modules.
