[0021] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present utility model, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present utility model.

[0023] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships.

In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0029] The working principle of this application is:

[0030] When the connecting pole ear 10 of the lamp bead is pressed into the limiting groove 2, the triangular wedge 3 will limit the connecting pole ear 10 to prevent the connecting pole ear 10 from being separated from the limiting groove 2;

[0031] A vertically arranged heat dissipation pipe 8 is formed inside the side wall of the heat sink body 1. The upper part of the heat dissipation pipe 8 passes through the outside of the heat sink body 1, and the lower part of the heat dissipation pipe 8 passes through the inside of the heat sink body 1, so that the upper gas is connected with the inside of the heat sink body 1. Since the upper part of the heat dissipation pipe 8 is far away from the main board, the air temperature above the heat dissipation pipe 8 is relatively low, and the air temperature inside the heat sink body 1 and the heat dissipation slot 4 is relatively high, so that convection can be formed to improve the heat dissipation effect, thereby quickly taking away the heat;

[0032] A heat dissipation pipe 8 is provided corresponding to the heat dissipation groove 4, and the heat dissipation groove 4 and the heat dissipation pipe 8 are arranged opposite to each other, so as to further enhance the convection effect and the heat dissipation effect.
