[0031] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a light-emitting component, including:

[0032] Lamp beads 100;

[0033] A lamp board 200 on which the lamp beads 100 are disposed; and

[0034] The lens 300 covers the lamp bead 100; the lens 300 is provided with a connector 310 and a protrusion 320; the connector 310 is fixedly connected to the lamp board 200; the protrusion 320 abuts against the lamp board 200 to form a heat dissipation groove S between the lens 300 and the lamp board 200; the heat dissipation groove S is connected to the outside.

[0035] In the technical solution of the embodiment of the present application, a protrusion 320 and a connecting piece 310 are protruded through the side of the lens 300 facing the lamp board 200; the connecting piece 310 is connected to the lamp board 200 to fix the lens 300 on the lamp board 200 in a manner of covering the lamp bead 100; the protrusion 320 abuts against the side of the lamp board 200 facing the lens 300, thereby forming a heat dissipation groove S between the lens 300 and the lamp board 200 to facilitate heat dissipation; therefore, compared with the prior art, the light-emitting component proposed in the present application has a protrusion 320 that forms a heat dissipation groove S between the lens 300 and the lamp board 200, thereby improving the heat dissipation effect and effectively reducing the risk of the lens 300 falling off or shifting due to heat.

[0036] In the technical solution of the embodiment, the outside world is the area outside the lens 300 .

[0037] As an optional implementation of the above embodiment, Figure 2 As shown, the protrusion 320 is connected to the connecting member 310. The protrusion 320 is connected to the connecting member 310, which increases the structural strength of the connecting member 310 and improves the stability of the connection between the lens 300 and the light board 200; the protrusion 320 abuts against the side of the light board 200 facing the lens 300, thereby forming a heat dissipation groove S between the lens 300 and the light board 200, and the heat of the lens 300 and the light board 200 can flow out from the heat dissipation groove S to the outside, avoiding heat accumulation and facilitating heat dissipation; therefore, compared with the prior art, the light-emitting assembly proposed in the present application can form a heat dissipation groove S between the lens 300 and the light board 200, and can also strengthen the structural strength of the connecting member 310, improve the stability of the connection between the lens 300 and the light board 200, and effectively reduce the risk of the lens 300 falling off or shifting due to heat.

[0038] In some embodiments, the connector 310 is provided with the bumps 320 on both sides of the lens 300 in the circumferential direction. Figure 2 As shown, the connecting member 310 has a first side and a second side in the circumferential direction of the lens 300 , and both the first side and the second side are provided with a bump 320 to ensure that the connecting member 310 is subjected to uniform force on both sides of the circumferential direction of the lens 300 .

[0039] In the embodiment, the thickness of the bumps 320 on both sides of the two pieces is consistent, so that the heat dissipation slots S on both sides of the connecting piece 310 are uniform.

[0040] In some embodiments, the protrusion 320 has a first end 321 and a second end 322, wherein the first end 321 is connected to the connector 310, and the second end 322 is away from the connector 310 along the circumference of the lens 300. In the embodiment, the protrusion 320 extends away from the connector 310 along the circumference, on the one hand, to ensure the structural strength of the connector 310, so as to strengthen the structural strength of the connector 310; on the other hand, to ensure that there is a sufficient contact area between the protrusion 320 and the light board.

[0041] As an optional implementation of the above embodiment, the number of the connecting members 310 is multiple, and the multiple connecting members 310 are arranged at intervals along the circumference of the lens 300. The connection reliability and stability between the lens 300 and the light board 200 are improved. Figure 3 As shown, there are three connectors 310, and the three connectors 310 are arranged at intervals along the circumference of the lens 300. In some embodiments, there may be two or more connectors 310, and the number is determined according to the area of ​​the bottom surface 340 of the lens 300, and there is no excessive restriction on the number. For a conventional lens 300, it is a preferred embodiment to have three or four connectors 310.

[0042] Each of the connecting members 310 is connected to a protrusion 320 on at least one side of the circumference of the lens 300. That is, in the embodiment, each of the connecting members 310 is connected to a protrusion 320 on at least one side of the circumference to strengthen the structure of the connecting member 310. Figure 3 As shown, each connecting member 310 is connected to the protrusions 320 on both sides in the circumferential direction.

[0043] In the embodiment, the bumps 320 connected to the adjacent connectors 310 are spaced apart from each other in the circumferential direction of the lens 300. That is, the bumps 320 connected to the adjacent connectors 310 are spaced apart from each other, so that the heat dissipation slots S are connected to the outside to discharge heat.

[0044] As an optional implementation of the above embodiment, the protrusion 320 is provided between two circumferentially adjacent connecting members 310. Providing the protrusion 320 between two circumferentially adjacent connecting members 310 can improve the uniformity of the heat dissipation slot S and make the heat dissipation uniform. For example, each of the connecting members 310 is connected to a protrusion 320 on at least one side of the circumference of the lens 300. That is, in the embodiment, each of the connecting members 310 is connected to a protrusion 320 on at least one side of the circumference to strengthen the structure of the connecting member 310. Figure 3As shown, each connector 310 is connected to the protrusions 320 on both sides in the circumferential direction. In the embodiment, the protrusions 320 connected to the adjacent connectors 310 are spaced apart from each other in the circumferential direction of the lens 300. That is, the protrusions 320 connected to the adjacent connectors 310 are spaced apart from each other, so that the heat dissipation slots S are connected to the outside to discharge heat.

[0045] In the embodiment, the lens 300 is generally a central rotationally symmetrical structure, and thus the protrusion 320 is an arc-shaped structure.

[0046] As an optional implementation of the above embodiment, the side of the lens 300 facing the lamp board 200 is a bottom surface 340; the lens 300 has a light entrance hole 330, and the light entrance hole 330 extends from the bottom surface 340 toward the inside thereof, and the lamp bead 100 is located in the light entrance hole 330. The heat dissipation slot S is connected to the light entrance hole 330. In the embodiment, the heat generated by the lamp bead 100 is mainly concentrated in the light entrance hole 330. The heat dissipation slot S is connected to the light entrance hole 330, so that hot air can flow out of the light entrance hole 330 to facilitate heat dissipation. Figure 2 and Figure 3 As described above, since the protrusion 320 abuts against the lamp board 200, a gap is formed between the side of the lens 300 facing the lamp board 200 and the lamp board 200, and the gap is the heat dissipation slot S; the protrusion 320 is configured to occupy only a partial area of ​​the side of the lens 300 facing the lamp board 200, and the heat dissipation slot S is extended to the light entrance hole 330, connecting the two, thereby facilitating the heat of the light entrance hole 330 to be discharged from the heat dissipation slot S.

[0047] As an optional implementation of the above embodiment, the protrusion 320 and the connector 310 are arranged away from the light entrance hole 330. In the embodiment, the protrusion 320 and the connector 310 are arranged away from the light entrance hole 330, so as to avoid weakening the structural strength of the connector 310 due to the opening of the light entrance hole 330, thereby improving the structural strength of the connector 310; at the same time, during the installation process, since the connector 310 and the protrusion 320 are away from the light entrance hole 330, the connector 310 and the protrusion 320 can be prevented from causing damage to the lamp bead 100.

[0048] In an embodiment, in combination Figure 3 and Figure 5 As shown, the light entrance hole 330 is usually set in the central position of the lens 300. When the lamp bead 100 emits light, the light enters the lens 300 through the hole wall of the light entrance hole 330, and then is emitted to the outside from the light exit surface 350 of the lens 300 (the circumferential surface of the lens 300), completing the uniform light of the lamp bead 100.

[0049] As an optional implementation of the above embodiment, the connecting member 310 is a snap-fit ​​member. Figure 4As shown, the lamp board 200 is provided with a clamping hole 210, and the clamping member is clamped and matched with the clamping hole 210. That is, in the embodiment, the clamping connection between the lens 300 and the lamp board 200 facilitates the assembly of the lens 300. The protrusion 320 strengthens the structure of the connecting member 310 to improve the connection strength of the clamping member.

[0050] In the embodiment, the number of the clamping holes 210 and the number of the clamping parts are matched. After the clamping parts are clamped into the clamping holes 210, the lens 300 is fixed to the light board 200, and the position of the lens 300 relative to the light board 200 is determined. Compared with the existing gluing method, on the one hand, the clamping connection is relatively easier, and on the other hand, because the protrusion 320 strengthens the structure of the clamping part and forms a heat dissipation groove S due to the contact with the light board 200, it is biased towards heat dissipation, thus overcoming the technical problem that the gluing method is not conducive to heat dissipation and thus overcoming the technical problem that the gluing method is easy to be heated and cause the lens 300 to fall off or shift.

[0051] As an optional implementation of the above embodiment, the buckle has an undercut 311 ; the buckle passes through the clamping hole 210 , and the undercut 311 abuts against a side of the light board 200 away from the lens 300 .

[0052] Generally speaking, the lens 300 is a structure made of an elastic lens 300 material, so the fastener is elastic. During the installation process, the fastener can be inserted into the fastener hole 210 based on deformation, and then after it passes through the fastener hole 210, the buckle 311 restores the deformation, so that the buckle 311 abuts against the side of the lamp board 200 away from the lens 300, thereby realizing a snap connection between the fastener and the lamp board 200, and fixing the lens 300.
