Wherein each recess 310 is configured for assembling a number of light sources 40 distributed in a sequential arrangement. The light source 40 used may be an LED (light emitting diode) light source, and may be an LED package light source such as 2835 beads (patch light emitting diode having a length of 2.8mm and a width of 3.5 mm), 3030 beads (patch light emitting diode having a length of 3.0mm and a width of 3.0 mm), 3535 beads (patch light emitting diode having a length of 3.5mm and a width of 3.5 mm), 5050 beads (patch light emitting diode having a length of 5.0mm and a width of 5.0 mm).

Referring to fig. 4-6, fig. 4 is a top view of lens 100 in some embodiments of the present application; FIG. 5 is a schematic cross-sectional view of the lens 100 of the embodiment of FIG. 4 along the direction A-A; fig. 6 is a schematic cross-sectional structure of the lens 100 in the embodiment of fig. 4 along the direction B-B.

Wherein X, Y is shown in two directions in fig. 4 for the purpose of the corresponding description below. The first direction is the X direction, and the second direction is the Y direction. The first direction and the second direction intersect, and a plane in which the first direction and the second direction are located is a reference plane, which may be parallel to a plane in which the bottom surface 30 or the top surface 20 is located. Preferably, the X direction is perpendicular to the Y direction, the top surface 20 is parallel to the bottom surface 30, and the plane in which the first direction and the second direction lie is parallel to the plane in which the top surface 20 lies.

In some embodiments, the transparent board 10 includes a first edge 220 and a second edge 230 connected by bending, and the length of the first edge 220 is not smaller than the length of the second edge 230, i.e. the transparent board 10 may be rectangular. The first direction may be an extending direction of the first edge 220, and the second direction may be an extending direction of the second edge 230. Alternatively, the first edge 220 and the second edge 230 may be understood as two sides of the top surface 20, where the plane in which the first direction and the second direction are located, i.e. the reference plane, is the top surface 20. Alternatively, the first edge 220 and the second edge 230 may be understood as two sides of the bottom surface 30, where the plane in which the first direction and the second direction are located, i.e. the reference plane, is the bottom surface 30.

The plurality of convex portions 210 are sequentially and alternately arranged along the first direction, and correspondingly, the plurality of concave portions 310 are sequentially and alternately arranged along the first direction.

The projection of the convex portion 210 projected on the reference plane has a first width W1 in the first direction, and the projection of the concave portion 310 projected on the reference plane has a second width W2 in the first direction, and the first width W1 is larger than the second width W2. By setting the structure of the lens 100 with the first width W1 larger than the second width W2, the light condensing performance of the lens 100 can be improved, and the light emitting effect can be improved.

The projection of the protrusion 210 projected on the reference plane has a first length L1 in the second direction, the projection of the recess 310 projected on the reference plane has a second length L2 in the second direction, the first length L1 is not smaller than the second length L2, and the second length L2 is larger than the second width W2.

Alternatively, the light sources 40 mounted in each recess 310 are sequentially arranged along the second direction. The plurality of light sources 40 may be disposed at intervals in the recess 310, or may be disposed adjacent to each other in the recess 310. In this embodiment, by adopting a plurality of light sources 40 to sequentially set in the concave portion 310, compared with the conventional particle type light distribution lens, more light sources 40 can be placed on the same transparent plate body, that is, more light sources 40 can be assembled in a limited space, so that larger luminous power and higher light efficiency can be provided.

It can be appreciated that by the structure of the lens 100 with the first length L1 not smaller than the second length L2, astigmatism can be effectively prevented, light condensing performance of the lens 100 is improved, and light emitting effect is improved.

Further, the lens 100 may have a light exit surface 213 and a light entrance surface 313. Light emitted from the light source 40 mounted in the recess 310 enters the lens 100 from the light incident surface 313 and exits the lens 100 through the light emergent surface 213. Specifically, the exposed surface of the convex portion 210 may be configured to form the light-emitting surface 213 of the lens 100, and the exposed surface of the concave portion 310 may be configured to form the light-entering surface 313 of the lens 100. The light exit surface 213 is formed by at least one curved surface; or the light-emitting surface 213 is formed by splicing a plurality of planes; or the light emitting surface 213 is formed by splicing at least one plane and at least one curved surface. The light incident surface 313 is formed of at least one curved surface; or the light incident surface 313 is formed by splicing a plurality of planes; or the light incident surface 313 is formed by splicing at least one plane and at least one curved surface. The shapes of the light exit surface 213 and the light entrance surface 313 may be different.

In this embodiment, the light incident surface 313 may be formed by splicing three planes. The light-emitting surface 213 may be formed by splicing two 1/4 spherical curved surfaces and one semi-cylindrical curved surface, where the two 1/4 spherical curved surfaces are respectively disposed at two ends of the semi-cylindrical curved surface in the second direction.

A certain thickness is formed between the light emitting surface 213 and the light entering surface 313, a condensing body similar to a convex lens with a condensing function is formed between the light emitting surface 213 and the light entering surface 313, when the light emitted by the light source 40 assembled in the concave portion 310 enters the condensing body from the light entering surface 313, the light is refracted first and then is emitted out of the lens 100 from the light emitting surface 213, and the light spot emitted by the lens 100 with optical design is very uniform. The specific light-emitting effect is affected by factors such as the distance between the light source 40 and the light-incident surface 313, the thickness of the condenser, the internal structure of the condenser, the shapes of the light-incident surface 313 and the light-emitting surface 213, and the like. It should be noted that, the specific principle of the above-mentioned factors on the light emitting effect is relatively lengthy, and it is obvious to those skilled in the art that the present application does not further improve the light emitting effect, so that detailed description is omitted herein. Those skilled in the art can reasonably adjust the factors mentioned above according to actual needs.

In one embodiment, the top surface 20 and the bottom surface 30 of the transparent plate body 10 may each be square with a side length of 50 mm. The top surface 20 is provided with 4 convex portions 210 which are distributed at intervals along the first direction, and correspondingly, the bottom surface 30 is provided with 4 concave portions 310 which are distributed at intervals along the first direction, and the convex portions 210 are arranged in one-to-one correspondence with the concave portions 310. Each recess 310 is configured to mount a plurality of light sources 40, the plurality of light sources 40 being arranged in sequence along the second direction.

Wherein the second length L2 of the recesses 310 may be 46mm, and the second width W2 of the recesses 310 may be 10mm, i.e., the interval between adjacent recesses 310 is approximately 2mm. The first length L1 of the protrusions 210 may be 46mm, and the first width W1 of the protrusions 210 is 12mm, i.e., the interval between adjacent protrusions 210 is approximately 0.4mm.

When the light source 40 is 2835 beads (patch light emitting diodes with a length of 2.8mm and a width of 3.5 mm), the plurality of light sources 40 may be sequentially arranged along the second direction. In this case, each recess 310 can be equipped with 16 light sources 40, and a total of up to 64 light sources 40 can be equipped with 4 recesses 310.

With the granular lenses of the related art, however, the size of each of the granular lenses is larger than the size of the light source 40 on the basis of satisfying the condition that the interval between two adjacent granules is 0.4mm. Based on 2835 lamp pearls, on the premise of meeting the inter-particle distance distribution, 4 rows of particle bulges can be distributed at intervals in the first direction, and 6 rows of particle bulges can be distributed at intervals in the second direction, namely 24 2835 lamp pearls can be distributed.

It is apparent that the lens 100 according to the present embodiment can be provided with a significantly larger number of light sources 40 than the granular lens of the related art can be provided with.

It can be understood that when the lens size and the type of the light source beads are changed, the number of light sources that can be assembled can be correspondingly changed, and details are omitted.

For example, when the lens 100 is mounted, the positioning post and the positioning hole 50 may be used in combination, the positioning post is aligned with the positioning hole 50, and then the positioning post is inserted into the positioning hole 50 and fastened with a screw.

In order to prevent the positioning hole 50 from occupying excessive volume of the transparent plate body 10, the positioning hole 50 may be assembled and positioned in such a manner that adjacent first lens 101 and second lens 102 cooperate with each other to form the positioning hole 50. Specifically, a first positioning hole 510 communicating with the top surface 20 and the bottom surface 30 is formed at one end of the transparent plate body 10 of the first lens 101 close to the second lens 102, a second positioning hole 520 communicating with the top surface 20 and the bottom surface 30 is formed at one end of the transparent plate body 10 of the second lens 102 close to the first lens 101, and the first positioning hole 510 and the second positioning hole 520 are enclosed in a matching manner to form a positioning hole 50 communicating with both the top surface 20 and the bottom surface 30 of the first lens 101 and the top surface 20 and the bottom surface 30 of the second lens 102. The lenses 100 are assembled and positioned in a mode that the adjacent lenses 100 are mutually matched to form the positioning holes 50, so that excessive volume of the transparent plate body 10 is avoided, more areas are provided for assembling the light sources 40, more light sources 40 can be assembled under the condition of the same area of the bottom surface 30, and larger power or larger light efficiency can be provided in a limited area.
