The plane is perpendicular to the middle axis plane of each sub-eye lens, the plane is parallel to the light incoming surface of the lens, when the position of the lens needs to be adjusted to enable the intersected plane of the light rays emitted by the lens to correspond to the position needing to be irradiated, the light incoming surface of the lens is adjusted to enable the intersected plane of the light rays emitted by the lens to be parallel to the position needing to be irradiated, then the distance between the lens and the position needing to be irradiated is adjusted to enable the intersected plane of the light rays emitted by the lens to be coincident with the position needing to be irradiated, the light rays emitted by the lens are converged at the position needing to be irradiated at the moment, the adjustment of the lens is completed, and the position of the lens can be conveniently adjusted according to actual requirements.
Specifically, taking two adjacent sub-eye lenses 101 and 102 as an example, the intersection portion 12 of the sub-eye lenses 101 and 102 may emit two light rays respectively, the two light rays are emitted outwards in the form of surface light rays, and may intersect two light rays (the two light rays are also surface light rays) emitted by each sub-eye lens on two lines respectively, where the two lines are located on the same plane.
The two light rays respectively intersected with the two light rays emitted from the intersection portion 12 of the sub-eye lenses 101 and 102 may be two light rays emitted from any one sub-eye lens, two light rays emitted from two sub-eye lenses respectively, or two light rays emitted from a plurality of sub-eye lenses under the combined action.

Fig. 2 is a schematic structural diagram of a lens according to another embodiment, where a plurality of sub-eye lenses form a plurality of sub-eye lens arrays, each sub-eye lens array includes a first sub-eye lens, a second sub-eye lens, a third sub-eye lens, and a fourth sub-eye lens, which are sequentially arranged, and in each sub-eye lens array, two light rays emitted from an intersection of two adjacent sub-eye lenses intersect with central axial surfaces of the two adjacent sub-eye lenses on the same plane, or two light rays emitted from an intersection of the second sub-eye lens and the third sub-eye lens intersect with central axial surfaces of the first sub-eye lens and the fourth sub-eye lens on the same plane.
Specifically, as shown in fig. 2, the light emitting surface 100 of the lens includes a plurality of sub-eye lenses, wherein each sub-eye lens may be divided into a plurality of sub-eye lens arrays, and the division criterion is that each sub-eye lens in the sub-eye lens arrays should satisfy that each sub-eye lens is sequentially and adjacently arranged along a certain direction, so that crossed sub-eye lenses may exist in each sub-eye lens array, for example, the sub-eye lenses 101, 102, 103, and 104 may form a sub-eye lens array, and the sub-eye lenses 102, 103, 104, and 105 may also form a sub-eye lens array.

Further, in one embodiment, in each group of sub-eye lens arrays, two paths of light rays emitted from the intersection of two adjacent sub-eye lenses intersect with the central axial plane of the two adjacent sub-eye lenses, and the two intersection lines are located on the same plane. Since repeated sub-eye lenses may exist in each group of sub-eye lens arrays, for all the sub-eye lenses on the light exit surface 100, the light rays emitted from each intersection part intersect with the central axis plane of each sub-eye lens, so that compared with a parallel light lens, the lens of the embodiment can achieve the effect of light ray enhancement, and because each intersection line is located on the same plane, light spots formed by the light rays on the plane also have uniformity. For example, as shown in fig. 3, taking the adjacent sub-eye lens 101 and sub-eye lens 102 as an example, the intersection 12 of the sub-eye lens 101 and sub-eye lens 102 refracts two light rays forming a certain angle with the parallel light rays, wherein one light ray intersects with the central axis face 011 of the sub-eye lens 101 at the plane L, and the other light ray intersects with the central axis face 022 of the sub-eye lens 102 at the plane L.

In one embodiment, in each sub-eye lens array, the intersection portion of two adjacent sub-eye lenses may protrude outward in the light exiting direction. As shown in fig. 5, taking the sub-eye lenses 101 and 102 as an example, the intersection portion 12 of the sub-eye lenses 101 and 102 protrudes outward in the light exiting direction (for comparison, the dotted line in the figure depicts the shape of the tangent plane of the light exiting surface 100 when it exits parallel light, which is represented by the curve 201), at this time, two light rays exiting from the intersection portion 12 of the sub-eye lenses 101 and 102 intersect with the central axis plane 011 of the sub-eye lens 101 and the central axis plane 022 of the sub-eye lens 102, respectively, and both the two intersection lines are located on the plane L (see fig. 3).
In another embodiment, in each sub-eye lens array, the intersection portion of two adjacent sub-eye lenses may also be recessed in the light incident direction. As shown in fig. 6, taking the sub-eye lenses 102 and 103 as an example, the intersection portion 23 of the sub-eye lenses 102 and 103 is recessed in the light incident direction (for comparison, the dotted line in the figure depicts the shape of the tangent plane of the light emitting surface 100 when emitting parallel light, which is represented by a curve 201), at this time, two paths of light emitted from the intersection portion 23 of the sub-eye lenses 102 and 103 intersect with the central axis plane 011 of the sub-eye lens 101 and the central axis plane 044 of the sub-eye lens 104, respectively, and both the two intersection lines are located on the plane L (see fig. 4).
