[0043] The connecting components 4 are provided with multiple and one-to-one correspondence with the multiple connecting grooves 22. The connecting components 4 include a connecting rod 41 and a connecting block 42. The connecting rod 41 is fixedly mounted on the outer wall of the mounting member 13, and the connecting rod 41 is arranged along the axis of the mounting member 13 and has elasticity. The connecting block 42 is integrally arranged on the top of the connecting rod 41 and on the side wall close to the lamp body shell 2. At the same time, the connecting rod 41 and the connecting block 42 both pass through the connecting groove 23 and extend into the connecting groove 22, so that the connecting block 42 is pressed against the connecting groove 22 for positioning under the elastic force of the connecting rod 41.

[0044] When the mounting member 13 is installed, multiple connecting blocks 42 are squeezed to extend into the slot body 1 21, so that multiple connecting blocks 42 are pressed against the slot body 1 21, and the mounting member 13 is pushed so that multiple connecting blocks 42 pass through the slot body 1 21 and the connecting slot 23 and extend into the connecting slot 22, and the squeezing of the connecting blocks 42 is released, the connecting blocks 42 are pressed against the connecting slot 22, and the connecting rod 41 is pressed against the connecting slot 23 for positioning, and then the mounting member 13 is rotated so that the connecting rod 41 and the connecting blocks 42 are misaligned with the connecting slot 23, and the connecting rod 41 is pressed against the inner side wall of the lamp body shell 2 for positioning, thereby realizing the installation of the mounting member 13 on the lamp body shell 2; when removing, the mounting member 13 is rotated so that the connecting rod 41 is pressed against the connecting slot 23 under the action of elastic force, which indicates that the angle is rotated in place, and then the mounting member 13 is pulled downward so that the connecting blocks 42 and the connecting rod 41 pass through the connecting slot 23 and the slot body 1 21 in turn, thereby realizing the removal of the mounting member 13.

[0045] Reference Figure 1 and Figure 2 There are multiple positioning components 5 arranged in a circular array around the axis of the lamp body shell 2. The positioning components 5 include a positioning rod 51 and two positioning blocks 52.

The second chamfer 54 facilitates the positioning ring 31 to squeeze the multiple positioning blocks 52 away from each other, so that the positioning ring 31 is more easily snap-fitted and installed on the snap-fit ​​space 53 for positioning.

[0047] Reference Figure 2 and Figure 3 A second groove body 24 is coaxially opened on the inner side wall of the top of the lamp body shell 2, a third groove body 25 is coaxially opened on the inner side wall of the lamp body shell 2 and located below the second groove body 24, and a fourth groove body 26 connected to the second groove body 24 is opened on the third groove body 25 along the axis of the lamp body shell 2; the top of the lamp body shell 2, i.e., one end close to the direction adjustment rod 12, is in an open state, and a blocking component 6 for blocking the opening is provided at the top opening of the lamp body shell 2.

[0048] The blocking assembly 6 includes a blocking plate 61 and a blocking rod 62.

The installation and disassembly methods of the blocking plate 61 and the mounting member 13 are the same, which will not be repeated here.

[0049] A plug-in board 7 is slidably mounted on the lamp housing 2 through the opening, and the plug-in board 7 can also be taken out through the bottom of the lamp housing 2. The plug-in board 7 is pressed against the top of the light source 3 under the action of gravity for positioning, so the plug-in board 7 and the multiple clamping spaces 53 can realize the positioning of the two ends of the light source 3, thereby improving the stability of the light source 3 during operation. The plug-in board 7 is provided with multiple screws for fixing the plug-in board 7 and the top of the light source 3. The plug-in board 7 is provided with multiple through holes 71 for the screws to pass through at intervals, and the number of through holes 71 can be more than the number of screws. The vacant through holes 71 can be used for heat dissipation of the light source 3 and the passage of wires.

[0050] A plurality of heat sinks 72 are fixedly mounted on the upper surface of the plug board 7. The heat sinks 72 are used to achieve heat dissipation and can enhance the strength of the plug board 7. A plurality of heat dissipation spaces 73 for heat dissipation of the light source 3 are formed between the plug board 7 and the inner side wall of the lamp body shell 2. A plurality of air inlet holes 27 are arranged at intervals on the lamp body shell 2 and corresponding to the heat dissipation spaces 73. The air inlet holes 27 are arranged along the axis of the lamp body shell 2 and extend to the upper and lower sides of the plug board 7. The air inlet holes 27 are used for the cold air of the shell to enter. The heat generated by the light source 3 moves upward through the heat dissipation space 73 and then dissipates through the heat dissipation holes 65. The movement of the hot air allows the cold air from the outside to enter through the air inlet holes 27, thereby accelerating the heat dissipation of the light source 3, increasing the life of the light source 3, and reducing the number of maintenance times.

[0051] The working principle of the embodiment of the present application is as follows:

[0052] When the light source component 3 is started, the heat generated by the light source component 3 is dissipated through the heat dissipation space 73 and the heat dissipation holes 65. At the same time, the heat can also be dissipated through the heat sink 72, and the external cold air enters through the air inlet hole 27, which improves the heat dissipation effect of the light source component 3, increases the life of the light source component 3, reduces the number of maintenance times, and reduces the maintenance cost.

[0053] When the light source component 3 is damaged and needs to be replaced, rotate the mounting component 13 to align the connecting rod 41 and the connecting block 42 with the connecting groove 23, pull the mounting component 13 to remove the light source component 3 and the plug-in board 71 together, then move the multiple positioning rods 51 away from each other, remove the light source component 3 for replacement, and snap-fit ​​the new light source component 3 into the multiple snap-fit ​​spaces 53 for positioning, then snap-fit ​​the connecting block 42 into the connecting groove 22, and then rotate the mounting component 13 for positioning, thereby completing the replacement of the light source component 3, greatly improving the efficiency of maintenance while reducing maintenance costs.

[0054] Example 2

[0055] Reference Figure 1 The difference between this embodiment and the first embodiment is that a heat dissipation pipe 81 is also inserted and installed at the air inlet 27, and a positioning piece 82 is provided on the heat dissipation pipe 81 for positioning against the inner wall of the lamp body shell 2. The heat dissipation pipe 81 is connected to the inside and outside of the lamp body shell 2 and is made of metal. The material of the heat dissipation pipe 81 is preferably copper. The heat dissipation pipe 81 can introduce the external cold air into the lamp body shell 2 for heat dissipation, and the heat dissipation pipe 81 itself can also achieve heat dissipation. At the same time, it can also be replaced in time, thereby improving the heat dissipation effect of the light source 3 and the life of the light source 3.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
