[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1-5A high heat dissipation copper guide column lamp bead includes a fixing seat, a lamp body (not shown in the figure) is arranged on the fixing seat, the fixing seat includes a seat body 1, the seat body 1 can be injection molded by PPA plastic (high temperature resistant nylon), a mounting groove 11 is arranged on the top of the seat body 1, and the lamp body can be installed on the top of the mounting groove 11. This is a prior art and will not be repeated here; a bracket 2 is arranged in the mounting groove 11, and the bracket 2 can be formed by stamping copper with a mold and electroplating. A plurality of pins 23 are arranged at both ends of the bracket 2, and the pins 23 protrude from the end surface of the seat body 1 for connecting with an external circuit. The bracket 2 is provided with two A slot 21 is provided, and the slot 21 can pass through the bracket 2 and the base body 1. The slot 21 passes through a heat dissipation column 3, and the heat dissipation column 3 can be a square copper column to provide excellent thermal conductivity. The bottom of the heat dissipation column 3 passes through the bottom of the base body 1. A pre-fixing device 4 is provided between the slot 21 and the heat dissipation column 3, so that the heat dissipation column 3 can be effectively pre-fixed during the installation process, ensuring that it can be accurately and stably fixed on the bracket 2, avoiding the problem of installation deviation, and improving the installation accuracy and stability of the heat dissipation column 3, thereby improving the heat dissipation performance and service life of the lamp beads.

[0022] In some embodiments, the pre-fixing device 4 includes two fixing grooves 41, and the two fixing grooves 41 are symmetrically arranged on the two side walls of the slot 21. An insert block 42 is provided in each fixing groove 41, and a rebound member 43 is provided between the insert block 42 and the side wall of the slot 21. The rebound member 43 can be a plurality of evenly distributed springs, and the plurality of springs are arranged between the insert block 42 and the side wall of the slot 21. The rebound member 43 is used to provide elastic force for the insert block 42 in the fixing groove 41 so that it can pop outward. Positioning grooves 31 are provided at the corresponding positions of the insert block 42 on both sides of the heat dissipation column 3, and the insert block 42 can be plugged into and matched with the positioning grooves 31; when the heat dissipation column 3 is inserted into the slot 21, the insert block 42 is squeezed by the heat dissipation column 3 and moves inward, compressing the rebound member 43. When the positioning groove 31 of the heat dissipation column 3 reaches the position of the insert block 42, the insert block 42 pops out under the elastic force of the rebound member 43 and is inserted into the positioning groove 31 to pre-fix the heat dissipation column 3; at the same time, after the lamp bead is completely encapsulated, the connection strength between the heat dissipation column 3 and the bracket 2 is enhanced, thereby improving the stability of the lamp bead.

[0023] In some embodiments, a frustum is provided at the bottom of the heat dissipation column 3 to facilitate the insertion of the heat dissipation column 3 into the slot 21, and an arc surface is provided on the side of the insert block 42 away from the slot 21 to reduce the resistance when the heat dissipation column 3 is inserted, making the heat dissipation column 3 smoother during installation and reducing the difficulty of installation.

[0024] In some embodiments, a limit groove 22 is provided on the top of the slot 21, and a limit plate 32 is provided on the top of the heat dissipation column 3. The limit plate 32 can be plugged into and matched with the limit groove 22. When the heat dissipation column 3 is fully inserted into the slot 21, the limit plate 32 is plugged into and matched with the limit groove 22, further limiting the movement of the heat dissipation column 3 and improving its installation stability. The height of the limit plate 32 can be equal to the depth of the limit groove 22, so that when the heat dissipation column 3 is fully inserted into the slot 21, the top surface of the heat dissipation column 3 is flush with the top surface of the bracket 2, thereby ensuring the contact area between the heat dissipation column 3 and the lamp body, while avoiding the influence of the heat dissipation column 3 on the installation of the lamp body on the fixed seat.

[0025] The specific installation principles are as follows:

[0026] When the heat sink 3 needs to be installed, first align the bottom of the heat sink 3 with the entrance of the slot 21, and then slowly insert it downward. During the insertion process, the two sides of the heat sink 3 will squeeze the plug 42, causing it to move into the fixing slot 41 and compress the resilient member 43. When the positioning slot 31 of the heat sink 3 reaches the position of the plug 42, the resilient member 43 recovers its deformation, and the plug 42 pops out under the elastic force of the resilient member 43 and is inserted into the positioning slot 31, thereby pre-fixing the heat sink 3.

[0027] At the same time, the limiting plate 32 on the top of the heat dissipation column 3 will be inserted into the limiting groove 22 on the top of the slot 21 to further limit the movement of the heat dissipation column 3. In this way, the heat dissipation column 3 is stably fixed on the bracket 2. Then glue is dripped between the heat dissipation column 3 and the slot 21 to further improve the stability of the installation of the heat dissipation column 3; the flat surface of the heat dissipation column 3 is solidified, the alloy wire is welded, and clear glue is dripped to complete the encapsulation of the lamp beads.

[0028] During the operation of the lamp beads, the heat generated is quickly transferred to the external environment through the heat dissipation column 3, thus achieving efficient heat dissipation.
