[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-5 The optical module 10 according to an embodiment of the present application is described. The optical module 10 includes a heat sink, a first circuit board, an inner lens 12, and a second circuit board.

[0024] A receiving cavity is formed within the heat sink. A first circuit board is disposed within the receiving cavity, and the first circuit board has first light-emitting particles 11 arranged sequentially along its width. An inner lens 12 is disposed within the receiving cavity, and the inner lens 12 has a first light-incident surface 121 and a first light-emitting surface 122. The first light-incident surface 121 is correspondingly disposed with respect to the first light-emitting particles 11. An ultra-widening lens 13 is disposed on one side of the inner lens 12 along its width, and the ultra-widening lens 13 is disposed adjacent to the first light-emitting surface 122. A second circuit board is disposed within the receiving cavity, and the second circuit board has second light-emitting particles 14, and the second light-emitting particles 14 are correspondingly disposed with respect to the ultra-widening lens 13.

[0025] Currently, increasing the beam width of low beams is significant for improving driving safety and expanding the field of vision, helping drivers to more clearly perceive conditions on both sides of the road, especially in complex road conditions such as curves. However, existing wide-beam low beam modules have limitations, with beam widths mostly around 40°. To solve this problem, it is usually necessary to add cornering lights or other auxiliary lighting equipment, but this not only increases the complexity of the vehicle's lighting system but also leads to an increase in the overall vehicle cost.

[0026] In response, this application proposes an optical module 10 that improves illumination width and reduces cost through an ultra-wide lens 13.

[0027] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the optical module 10 includes a heat sink, a first circuit board, an inner lens 12, and a second circuit board. The heat sink can have a cavity inside, and the first circuit board can be disposed within the cavity. The first circuit board can also have first light-emitting particles 11. There can be multiple first light-emitting particles 11, which can be arranged sequentially along the width direction. The width direction can be the width direction of the heat sink, i.e., the width direction of the inner lens 12 (e.g.,...). Figure 1(As shown in the Y direction), the inner lens 12 can be disposed within the receiving cavity, and the inner lens 12 can have a first light-incident surface 121 and a first light-exit surface 122. The first light-incident surface 121 can be correspondingly disposed with the first light-emitting particle 11. The light emitted by the first light-emitting particle 11 can enter the inner lens 12 through the first light-incident surface 121, and after reflection within the inner lens 12, it is emitted from the first light-exit surface 122, thereby realizing the low beam function of the optical module 10. The number of the first light-emitting particles 11 can be set according to actual needs. In a specific embodiment, the number of the first light-emitting particles 11 can be four. Optionally, the optical module 10 of this application embodiment can be a single low beam module, independently realizing the low beam function.

[0028] Furthermore, an ultra-widening lens 13 can be provided on one side of the inner lens 12 along the width direction. It is understood that the ultra-widening lens 13 and the inner lens 12 can be an integral structure. In some embodiments, the materials of the inner lens 12 and the ultra-widening lens 13 can be PC material (polycarbonate). The ultra-widening lens 13 can be disposed adjacent to the first light-emitting surface 122. The second circuit board can be disposed in the receiving cavity, and the second circuit board can have a second light-emitting particle 14. The second light-emitting particle 14 can be disposed corresponding to the ultra-widening lens 13. It is understood that the light emitted by the second light-emitting particle 14 can pass through the ultra-widening lens 13 and illuminate the outside. The ultra-widening lens 13 can increase the illumination width of the light. It should be noted that when the light emitted by the first light-emitting particle 11 can illuminate the outside through the inner lens 12, the light emitted by the second light-emitting particle 14 can illuminate one side of the inner lens 12 along the width direction through the ultra-widening lens 13, thereby increasing the width. Compared with the prior art, corner lights and other structures can be eliminated, reducing the overall cost of the vehicle lights and reducing the complexity of the vehicle lights.

[0029] In short, the optical module 10 of this application embodiment has an inner lens 12, which may have a first light-emitting surface 122, and an ultra-wide lens 13 may be provided on one side of the inner lens 12 along the width direction. The ultra-wide lens 13 may be provided adjacent to the first light-emitting surface 122. The light emitted by the first light-emitting particle 11 can be illuminated to the outside through the inner lens 12, and the light emitted by the second light-emitting particle 14 can be illuminated to the outside through the ultra-wide lens 13, thereby effectively improving the illumination width and illumination capability of the optical module 10 and reducing the overall cost of the vehicle lamp.

[0030] like Figure 1 As shown, in some embodiments of this application, the optical module 10 further includes an outer lens 15. The outer lens 15 can be disposed at one end of the heat sink along its length direction, which can be the length direction of the heat sink, i.e., the length direction of the inner lens 12 (e.g., ...). Figure 1As shown in the X direction, the outer lens 15 can be respectively disposed corresponding to the first light-emitting surface 122 and the ultra-widening lens 13. The ultra-widening lens 13 can be convex toward the outer lens 15. It is understood that this convex structure can further refract and diffuse the light, thereby enhancing the light-widening effect. In some embodiments, the material of the outer lens 15 can be PMMA (polymethyl methacrylate).

[0031] Furthermore, such as Figure 2 As shown, at least a portion of the outer lens 15 can extend obliquely in the length direction to form a curved surface 151 along the width direction. The ultra-wide lens 13 is correspondingly arranged with the curved surface 151. It can be understood that the edge of the outer lens 15 can be a curved structure, and the curved surface 151 can be formed inside the curved structure. The ultra-wide lens 13 can be correspondingly arranged with the curved surface 151, thereby increasing the light illumination width in the oblique direction of the outer lens 15.

[0032] like Figure 2 As shown, in some embodiments of this application, the ultra-wide lens 13 may have a second light-incident surface 131 and a second light-outcident surface 132. The second light-incident surface 131 may be correspondingly arranged with the second light-emitting particle 14, and the second light-outcident surface 132 may be correspondingly arranged with the curved surface 151. The light emitted by the second light-emitting particle 14 can be irradiated into the interior of the ultra-wide lens 13 through the second light-incident surface 131. After being refracted inside the ultra-wide lens 13, the light is irradiated out through the second light-outcident surface 132. The radius of curvature of the second light-incident surface 131 is R, which satisfies the relationship: 14mm≤R≤18mm. That is, the radius of curvature of the second light-incident surface 131 can be any value between 14mm and 18mm. For example, the radius of curvature of the second light-incident surface 131 can be, but is not limited to, 14mm, 15mm, 16mm, 17mm, 18mm, etc. This arrangement can ensure the refraction and focusing effect of the light passing through the ultra-wide lens 13, so as to achieve a wider beam width and reduce aberrations and light loss.

[0033] like Figure 2 As shown, in some embodiments of this application, the distance between the second light-emitting particle 14 and the second light-incident surface 131 along the length direction is L, satisfying the relationship: 4mm≤L≤10mm. That is, the distance between the second light-emitting particle 14 and the second light-incident surface 131 along the length direction can be any value between 4mm and 10mm. For example, the distance between the second light-emitting particle 14 and the second light-incident surface 131 along the length direction can be, but is not limited to, 4mm, 6mm, 8mm, 10mm, etc. This setting can ensure the refraction and focusing effect of the light passing through the ultra-wide lens 13, so as to achieve a wider beam width.

[0034] like Figure 1 and Figure 2As shown, in some embodiments of this application, the second light-incident surface 131 is a cylindrical curved surface with an arc in the width direction and no arc in the height direction. The second light-exiting surface 132 is a smooth arc surface. The second light-exiting surface 132 can refract the incident light rays to the outer direction in the width direction and converge them in the height direction within the range of -0.57° to -10°, so as to facilitate the superposition of the light patterns and near-light patterns after passing through the ultra-wide lens 13.

[0035] like Figure 1 As shown, in some embodiments of this application, the inner lens 12 may include a central brightness portion 123 and a width portion 124. The central brightness portion 123 and the width portion 124 may be arranged sequentially along the width direction. The light pattern formed by light passing through the central brightness portion 123 and the light pattern formed by light passing through the width portion 124 can be superimposed to form a near beam pattern. The width portion 124 includes a first reflective portion 1241 and a second reflective portion 1242. The first reflective portion 1241 and the second reflective portion 1242 may be arranged sequentially along the width direction. The light-incident end of the first reflective portion 1241 and the light-incident end of the second reflective portion 1242 extend obliquely away from each other. This arrangement allows the light emitted by the first reflective portion 1241 and the second reflective portion 1242 to have a wider light pattern, thereby improving the overall width of the near beam pattern. Correspondingly, the first light-emitting particle 11 can be rotated as needed to match the first reflective portion 1241 and the second reflective portion 1242.

[0036] like Figure 3 As shown, in some embodiments of this application, the angle between the positive light emission direction and the length direction of the first reflective part 1241 is α, satisfying the relationship: 0 < α ≤ 15°. That is, the angle between the positive light emission direction and the length direction of the first reflective part 1241 can be greater than 0 and less than or equal to 15°. For example, the angle between the positive light emission direction and the length direction of the first reflective part 1241 can be, but is not limited to, 5°, 8°, 10°, 13°, 15°, etc. The angle between the positive light emission direction and the length direction of the second reflective part 1242 is α, satisfying the relationship: 0 < α ≤ 15°. That is, the angle between the positive light emission direction and the length direction of the second reflective part 1242 is α, satisfying the relationship: 0 < α ≤ 15°. The angle between the positive light emission direction of the second reflector 1242 and the length direction can be greater than 0 and less than or equal to 15°. For example, the angle between the positive light emission direction of the second reflector 1242 and the length direction can be, but is not limited to, 5°, 8°, 10°, 13°, 15°, etc. By setting the angle between the positive light emission direction of the first reflector 1241 and the length direction and the angle between the positive light emission direction of the second reflector 1242 and the length direction within the above range, the light emitted by the first reflector 1241 and the second reflector 1242 can have a wider light pattern, thereby improving the overall beam width of the near beam.
