[0032] Reference Figure 1 and Figure 2 As shown, the present application provides a lens 100. Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lens 100 is used to cover the lamp bead 220, and the lamp bead 220 is arranged on the circuit board 210. Figure 1 and Figure 2 As shown, the lens 100 includes a lens body 110, an extension handle 120 and a buckle 130; one end of the extension handle 120 is connected to the lens body 110, and the other end is provided with the buckle 130. Figures 1 to 6 As shown, the buckle 130 is configured to be detachably connected to the circuit board 210. In the technical solution of the embodiment of the present application, an extension handle 120 is provided on the lens body 110, and a buckle 130 is provided on the side of the extension handle 120 away from the lens body 110; when the lens body 110 is covered on the lamp bead 220, the buckle 130 causes the card slot 211 on the circuit board 210 to deform, and the buckle 130 is inserted into the card slot 211. Due to the deformation of the card slot 211, the card slot 211 is fixed to the circuit board 210 based on the deformation, so that the lens 100 can be fixed without the glue dispensing process and the glue solidification process, so as to achieve the purpose of convenient assembly of the lens 100; at the same time, since the glue dispensing process and the glue solidification process are omitted, the process cost can be saved.

[0033] In the embodiment, the lens body 110 , the extension handle 120 and the buckle 130 are an integrally formed structure.

[0034] As an optional implementation of the above embodiment, Figure 2As shown, the buckle 130 includes a buckle body 131 and a guide base 132, the buckle body 131 is connected to the extension handle 120, and the guide base 132 is connected to an end of the buckle body 131 away from the extension handle 120. In an embodiment, the lens body 110, the extension handle 120, the buckle body 131 and the guide base 132 are an integrally formed structure.

[0035] When the lens body 110 covers the lamp bead 220, the buckle body 131 can cause the slot 211 on the circuit board 210 to deform and snap into the slot 211, and the guide base 132 abuts against one side of the circuit board 210 in the thickness direction to limit the movement of the lens 100 in the thickness direction of the circuit board 210. In an embodiment, during the assembly of the lens 100, when the buckle body 131 starts to move into the slot 211 and snaps into the slot 211, the guide base 132 follows the movement of the buckle body 131 to one side of the circuit board 210 in the thickness direction, abuts against the side of the circuit board 210, and then after the lens 100 is snapped into place, the movement of the lens 100 in the thickness direction can be limited.

[0036] Generally speaking, the circuit board 210 has a first side surface and a second side surface opposite to each other in the thickness direction. The first side surface is provided with a lamp bead 220. After the buckle body 131 is inserted into the slot 211, the first side surface abuts against the extension handle 120, and the second side surface is in contact with the guide base 132, thereby limiting the movement of the lens 100 in the thickness direction.

[0037] In the embodiment, the guide base 132 is formed by extending from the peripheral side of the buckle body 131 to the buckle body 131; for example, the buckle body 131 is a cylindrical structure, such as Figure 2 As shown, the guide base 132 is formed by extending from the outer circumference of the buckle body 131 along the radial direction of the buckle body 131; further, the guide base 132 is generally in a conical structure.

[0038] As an optional implementation of the above embodiment, the width of the buckle 130 is greater than the width of the opening 2111a of the slot 211, so as to cause the slot 211 to deform when the lens body 110 covers the lamp bead 220. In the embodiment, the width of the buckle 130 is greater than the width of the opening 2111a of the slot 211, and when the buckle 130 is inserted into the slot 211, the slot 211 is deformed, and the slot 211 clamps the buckle 130 after deformation, so that the lens 100 is fixed on the circuit board 210. In the embodiment, the width of the buckle 130 can be slightly greater than about 0.1 mm of the width of the opening 2111a, and its specific value is set according to the situation.

[0039] It should be noted that, since the shape of the buckle 130 is not specifically limited in the present application, the width of the buckle 130 is understood in a broad sense: the buckle 130 has a projection on the side 213, and the width of the projection in the width direction of the opening 2111a (usually the length direction of the side 213) is defined as the width of the buckle 130. For example, in some embodiments, the buckle 130 can be configured as a cylindrical structure, and the width of the buckle 130 is the diameter of the buckle 130.

[0040] As an optional implementation of the above embodiment, Figure 2 As shown, the number of the extension handles 120 is at least two, the number of the buckles 130 is at least two, and the other end of each of the extension handles 120 is provided with a buckle 130. In an embodiment, the extension handles 120 are arranged in sequence along the circumference of the lens body 110. Each extension handle 120 is provided with a buckle 130. In an embodiment, a plurality of slots 211 are correspondingly provided at the positions of the lamp beads 220 on the circuit board 210, and the number of the slots 211 is consistent with the number of the extension handles 120, and each buckle 130 is snapped into the corresponding slot 211, which is conducive to the reliable fixation of the lens 100.

[0041] As an optional implementation of the above embodiment, Figure 2 As shown, the number of the extension handles 120 is two, the number of the buckles 130 is two, and the line connecting the buckles 130 passes through the center of the lens body 110. In this embodiment, the buckle 130 can be inserted into the corresponding slot 211 by rotating the lens body 110, so as to facilitate the installation of the lens 100. Specifically, in this embodiment, a plurality of lamp beads 220 are provided on the circuit board 210. A slot 211 located on both sides 213 is correspondingly provided at the position of each lamp bead 220, and the opening 2111a of the slot 211 is provided on the side 213. The line connecting the centers of the slots 211 passes through the installation center of the lamp bead 220. When installing the lens 100, the lens body 110 can be covered on the lamp bead 220, and then the buckles 130 can be inserted into the corresponding slots 211 by rotating, so as to realize the glue-free fixation of the lens 100.

[0042] Reference Figure 5 and Figure 6 As shown, the embodiment of the present application further provides a light board 10, comprising:

[0043] A circuit board 210, wherein the circuit board 210 has a side 213 and a slot 211 with an opening 2111a disposed on the side 213;

[0044] A lamp bead 220 , wherein the lamp bead 220 is disposed on the circuit board 210 ; and

[0045] The lens 100 described above, the lens body 110 is covered on the lens body 110 ; the buckle 130 is clipped into the clip slot 211 .

[0046] In the technical solution of the embodiment of the present application, an extension handle 120 is provided on the lens body 110, and a buckle 130 is provided on the side of the extension handle 120 away from the lens body 110; when the lens body 110 is covered on the lamp bead 220, the buckle 130 is inserted into the slot 211 through the opening 2111a on the side 213, causing the slot 211 on the circuit board 210 to deform, and the slot 211 is fixed to the circuit board 210 based on the deformation of the slot 211 when inserted into the slot 211, so that the lens 100 can be fixed without the need for a dispensing process and a solid glue process, thereby achieving the purpose of convenient assembly of the lens 100; at the same time, since the dispensing process and the solid glue process are omitted, the process cost can be saved.

[0047] In some embodiments, Figure 3 As shown, the circuit board 210 is a strip structure, that is, the light board 10 is a light strip structure. A plurality of lamp beads 220 are arranged on the circuit board 210; around each lamp bead 220, a slot 211 is correspondingly arranged on the side 213 of the circuit board 210; the buckle 130 of each lens 100 is inserted into the slot 211 near the lamp bead 220 it covers.

[0048] In some embodiments, Figure 3 As shown, a plurality of lamp beads 220 are provided on the circuit board 210. A slot 211 located on both side edges 213 is provided at the position of each lamp bead 220, and the opening 2111a of the slot 211 is provided on the side edge 213. The line connecting the centers of the slots 211 passes through the installation center of the lamp bead 220. There are two extension handles 120, and there are two buckles 130, and the line connecting the buckles 130 passes through the center of the lens body 110. In this embodiment, the buckles 130 can be inserted into the corresponding slots 211 by rotating the lens body 110, so as to facilitate the installation of the lens 100. When installing the lens 100, the lens body 110 can be covered on the lamp bead 220, and then the buckles 130 can be inserted into the corresponding slots 211 by rotating, so as to realize the glue-free fixation of the lens 100.

[0049] As an optional implementation of the above embodiment, Figure 4As shown, the slot 211 includes a first section 2111 and a second section 2112. The first section 2111 has the opening 2111a and extends toward the inside of the circuit board 210 away from the opening 2111a. The second section 2112 is connected to an end of the first section 2111 away from the opening 2111a. The width of the opening 2111a is smaller than the width of the second section 2112. When the buckle 130 is inserted into the slot 211, the first section 2111 is deformed through the opening 2111a and then into the second section 2112. The first section 2111 can prevent the buckle 130 from falling out of the slot 211. In some embodiments, the shape of the slot 211 is similar to a stepped groove, such as a gourd groove. In the direction in which the buckle 130 is inserted, the slot 211 changes from narrow to wide, so that after the buckle 130 is inserted, the slot 211 deforms to clamp the buckle 130 and prevents the buckle 130 from falling out of the slot 211.

[0050] In some embodiments, the width of the second section 2112 may be slightly larger than the width of the buckle 130 , such as slightly larger than the width of the buckle 130 by 0.05 mm.

[0051] As an optional implementation of the above embodiment, Figure 4 As shown, the circuit board 210 is further provided with a notch groove 212, and the notch groove 212 is arranged near the card slot 211 to provide a deformation space for the card slot 211. Since the notch groove 212 is arranged near the card slot 211, it is beneficial to increase the elasticity of the card slot 211, and then when the buckle 130 starts to be inserted into the card slot 211 from the opening 2111a, the card slot 211 begins to deform toward the notch groove 212 under the action of the assembly force, which is beneficial for the buckle 130 to be inserted into the card slot 211. Generally speaking, the notch groove 212 is a strip structure.

[0052] As an optional implementation of the above embodiment, Figure 3 and Figure 4 As shown, the circuit board 210 has a length direction, and the side edge 213 extends along the length direction; the number of the notch grooves 212 is at least two, and two of the at least two notch grooves 212 are distributed on both sides of the card slot 211 in the length direction. In this embodiment, by providing a plurality of notch grooves 212, the resistance of the buckle 130 being inserted into the card slot 211 can be reduced; the two notch grooves 212 are respectively arranged on both sides of the card slot 211 in the length direction, which helps the card slot 211 to open when the buckle 130 is inserted, thereby making it easier for the buckle 130 to be inserted into the card slot 211.
