[0049] Headlights are tools for vehicles to illuminate the road at night and are also tools for issuing various vehicle driving signals. Headlights are mainly composed of a lamp housing, a light source, and an optical component (lens). In the prior art, after the light emitted by the light source passes through the lens, the light spot formed is prone to light spot tearing (such as Figure 1 As shown in the figure, the light spot is torn into two light spots on the left and right), the visual effect is uneven, and the light output quality is affected.

[0050] In view of this, please refer to Figure 2-Figure 12 A lens 100, an optical module 1000, and a vehicle lamp provided in an embodiment of the present invention can solve this problem, which will be described in detail below.

[0051] Please refer to Figure 1-Figure 5 An embodiment of the present invention provides a vehicle lamp, including a lamp housing, a light source 10 and an optical module 1000. The optical module 1000 and the light source 10 are both installed in the lamp housing. The light source 10 is away from the lens 100 relative to the light dispersing lens 200. The light dispersing lens 200 is used to evenly disperse the light emitted by the light source 10 on multiple lens collimating teeth 130. The optical module 1000 can avoid the phenomenon of light spot tearing, and the visual effect is more uniform, which ensures the light output quality.

[0052] Specifically, the optical module 1000 includes a light dispersing lens 200, a lens connector 300 and a lens 100, wherein the number of the light dispersing lenses 200 and the number of the lens connectors 300 are both multiple, and the multiple light dispersing lenses 200 and the multiple lens connectors 300 are connected in sequence.

[0053] In addition, the lens connector 300 is also connected to the light dispersing lens 200 and the lens body 110 at the same time. The lens connector 300 has three connecting ends arranged at an angle, and the three connecting ends are respectively connected to the lens body 110 and the adjacent light dispersing lens 200.

[0054] It is easy to understand that the light dispersing lens 200 and the lens 100 are arranged at intervals. The light dispersing lens 200 is close to the light source 10 relative to the lens 100. The light emitted by the light source 10 first passes through the light dispersing lens 200 and then is emitted through the lens 100. The lens connector 300, the light dispersing lens 200 and the lens 100 are all made of the same material.

[0055] The lens 100 includes a lens body 110, a plurality of arcuate lens portions 120 and a plurality of lens collimating teeth 130, wherein the plurality of arcuate lens portions 120 are arranged on one side of the lens body 110, and the plurality of arcuate lens portions 120 are arranged into a two-dimensional array along a first direction and a second direction, and the plurality of lens collimating teeth 130 are arranged in sequence on the other side of the lens body 110 along the first direction, and the lens collimating teeth 130 extend along the second direction, and the plurality of lens collimating teeth 130 respectively correspond to the plurality of arcuate lens portions 120 distributed along the first direction, wherein the length of the tooth root of the lens collimating tooth 130 along the first direction is equal to the total chord length of the arc of the arcuate lens portion 120 distributed along the first direction. In this embodiment, the length of the tooth root of the lens collimating tooth 130 along the first direction is equal to the chord length of the arc of one arcuate lens portion 120 distributed along the first direction.

[0056] It should be noted that, in this embodiment, the first direction and the second direction are perpendicular to each other, and the first direction and the second direction correspond to Figure 3 The X and Y directions in .

[0057] Among them, the arcuate lens portion 120 is away from the light dispersing lens 200 relative to the lens collimating teeth 130. The light dispersing lens 200 is used to disperse the light emitted by the light source 10. The light dispersed by the light dispersing lens 200 is incident on multiple lens collimating teeth 130. The lens collimating teeth 130 directs multiple light rays in parallel along the third direction (Z direction) to the incident surface of the arcuate lens portion 120, and then emits them through the refractive surface of the arcuate lens portion 120. The refractive surface of the arcuate lens portion 120 is used to diffuse the light. It should be noted that any two of the third direction, the first direction and the second direction are perpendicular to each other.

[0058] It is easy to understand that in this way, all light passing through the lens collimating teeth 130 can pass through the corresponding arc lens portion 120, avoiding the phenomenon of light spot tearing, making the visual effect more uniform, and ensuring the light output quality.

[0059] Please refer again Figure 3The lens body 110 is a rectangular parallelepiped structure, the incident surface of the arc lens portion 120 is a plane, the incident surface of the arc lens portion 120 is aligned with the refractive surface of the lens body 110, the refractive surface of the lens collimating teeth 130 is a plane, the refractive surface of the lens collimating teeth 130 is aligned with the incident surface of the lens body 110, and the incident surface of the lens collimating teeth 130 is composed of two inclined surfaces at an angle, which is used to facilitate the parallel projection of multiple light rays along the Z direction onto the corresponding incident surface of the arc lens portion 120.

[0060] Specifically, the lens body 110 , the plurality of arcuate lens portions 120 and the plurality of lens collimating teeth 130 are integrally formed and are all made of transparent material, and each lens collimating tooth 130 corresponds to a plurality of arcuate lens portions 120 distributed along the Y direction.

[0061] Next, please refer to Figure 5 and Figure 6 ,in Figure 6 for Figure 5 In the partially enlarged cross-sectional view, in this embodiment, the length of the tooth root of the lens collimating tooth 130 along the X direction is just equal to the chord length of the arc distributed along the first direction of the curved lens portion 120, and the lens collimating tooth 130 and the corresponding curved lens portion 120 are both distributed in the third direction (Z direction). At the same time, the center line of the tooth root of the lens collimating tooth 130 and the center line of the chord length of the arc distributed along the first direction of the corresponding curved lens portion 120 are collinear.

[0062] It should be noted that, in this embodiment, the refractive surface of the curved lens portion 120 is a convex curved surface 121. Specifically, the central area of ​​the refractive surface of the curved lens portion 120 is convex along the Z direction, so that the refractive surface of the curved lens portion 120 is a convex curved surface 121. Here, the arc of the curved lens portion 120 distributed along the first direction can be the arc at the highest point of the convex curved surface 121. The curvature of the convex curved surface 121 can be adjusted according to specific needs to diffuse light at different angles.

[0063] Of course, the middle area of ​​the refractive surface of the arc lens portion 120 is concave in the Z direction, so that the refractive surface of the arc lens portion 120 is a concave arc surface 122 (such as Figure 7 As shown), the curvature of the concave arc surface 122 can be adjusted according to specific needs to diffuse light at different angles.

[0064] In addition, in other embodiments, the length of the tooth root of the lens collimating tooth 130 along the X direction can be equal to the total chord length of the arcs distributed along the first direction of the multiple curved lens portions 120, for example, the sum of the chord lengths of the arcs distributed along the first direction of two curved lens portions 120, or the sum of the chord lengths of the arcs distributed along the first direction of three curved lens portions 120.

[0065] Please refer to Figures 8-11Next, the light dispersing lens 200 will be described in detail. The light dispersing lens 200 is used to refract and disperse the light emitted by the light source 10, and then project it onto the multiple lens collimating teeth 130. In order to facilitate the dispersion of the light, the refractive surface of the light dispersing lens 200 is a curved surface.

[0066] Specifically, the refractive surface of the light dispersing lens includes a first arc surface 201, a second arc surface 202 and a third arc surface 203 connected in sequence, the second arc surface 202 is convex or concave along the third direction, wherein the third direction is perpendicular to the first direction and the second direction, the first arc surface 201 and the third arc surface 203 are both circular arc surfaces, and the radius range of the first arc surface 201 is 1mm-20mm, and the radius range of the third arc surface 203 is 1mm-20mm.

[0067] Preferably, the radius of the first curved surface 201 is 10 mm, the radius of the third curved surface 203 is also 10 mm, and the first curved surface 201 and the third curved surface 203 are both convex circular arc surfaces. In this embodiment, the second curved surface 202 of the refractive surface of the light dispersing lens 200 is concave along the third direction (Z direction), that is, the middle area of ​​the refractive surface of the light dispersing lens 200 is concave. Of course, in other embodiments, the second curved surface 202 can also be convex along the third direction (Z direction), that is, the middle area of ​​the refractive surface of the light dispersing lens 200 is convex.

[0068] In order to further avoid the phenomenon of light spot tearing, the light dispersing lens 200 has a plurality of dispersing lens collimating teeth 210, and the plurality of dispersing lens collimating teeth 210 are arranged in sequence along the second direction (Y direction). The plurality of dispersing lens collimating teeth 210 are used to direct the light emitted by the light source 10 to be parallel to the incident surface of the lens 100 along the third direction (Z direction).

[0069] The length of the tooth root of the dispersed lens collimating tooth 210 along the second direction (Y direction) is equal to the chord length of the arc of the arc lens portion 120 distributed along the second direction. Each dispersed lens collimating tooth 210 can correspond to multiple arc lens portions 120.

[0070] The dispersed lens collimating teeth 210 and the corresponding arc surface lens portion 120 are both distributed in the third direction (Z direction). At the same time, the center line of the tooth root of the dispersed lens collimating teeth 210 and the center line of the chord length of the arc distributed along the second direction (Y direction) of the corresponding arc surface lens portion 120 are collinear.

[0071] It should be noted that the arc line of the arc lens portion 120 distributed along the second direction may be the arc line where the highest point of the convex arc surface 121 is located.

[0072] Of course, the length of the tooth root of the dispersion lens collimator tooth 210 along the Y direction may also be equal to the sum of the chord lengths of the arcs of at least two arcuate lens portions 120 distributed along the Y direction. For example, the length of the tooth root of the leftmost dispersion lens collimator tooth 210 along the second direction (the Y direction) is equal to the sum of the chord lengths of the arcs of the two arcuate lens portions 120 distributed along the second direction.

[0073] After the light emitted by the light source 10 passes through the optical module 1000 provided in this embodiment, the light spot formed will not have the phenomenon of light spot tearing, the visual effect is more uniform, and the light quality is guaranteed (such as Figure 12 shown).

[0074] To sum up, the lens 100 includes a lens body 110, a plurality of arcuate lens portions 120 and a plurality of lens collimating teeth 130, the plurality of arcuate lens portions 120 are all arranged on one side of the lens body 110, the plurality of arcuate lens portions 120 are arranged into a two-dimensional array along the first direction and the second direction, the plurality of lens collimating teeth 130 are arranged in sequence on the other side of the lens body 110 along the first direction, and the lens collimating teeth 130 extend along the second direction, and the plurality of lens collimating teeth 130 respectively correspond to the plurality of arcuate lens portions 120 distributed along the first direction, wherein the length of the tooth root of the lens collimating tooth 130 along the first direction is equal to the total chord length of the arc distributed along the first direction of at least one arcuate lens portion 120, so that the light passing through the lens collimating teeth 130 can pass through the corresponding arcuate lens portion 120, avoiding the phenomenon of light spot tearing, making the visual effect more uniform, and ensuring the light output quality.

[0075] The optical module 1000 includes a light-dispersing lens 200 and the above-mentioned lens 100. The light-dispersing lens 200 and the lens 100 are arranged at intervals. The arc lens portion 120 is away from the light-dispersing lens 200 relative to the lens collimating teeth 130. The light-dispersing lens 200 is used to disperse light to avoid the phenomenon of light spot tearing, making the visual effect more uniform and ensuring the light output quality.

[0076] The car lamp includes a lamp housing, a light source 10 and the above-mentioned optical module 1000. The optical module 1000 and the light source 10 are both installed in the lamp housing. The light source 10 is away from the lens 100 relative to the light dispersing lens 200. The light dispersing lens 200 is used to evenly disperse the light emitted by the light source 10 on multiple lens collimating teeth 130 to avoid the phenomenon of light spot tearing, making the visual effect more uniform and ensuring the light output quality.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
