The annular mounting groove 9 is opened inside the base 4, and the inner wall on the other side of the annular mounting groove 9 is rotatably connected to the outer wall of the bottom end of the lampshade 5.

[0028] The sealing connection assembly also includes a sealing ring 7 and a first sealing groove 11. The sealing ring 7 is integrally arranged on the outer side of the bottom end of the lampshade 5, and the sealing ring 7 adopts an annular structure with an L-shaped cross-section.

[0029] The sealing connection assembly also includes an annular sealing ring 8 and a second sealing groove 12 . The second sealing groove 12 is opened above the first sealing groove 11 , and the second sealing groove 12 is adapted to the annular sealing ring 8 . The annular sealing ring 8 is fixedly mounted on the outer side of the top end of the sealing ring 7 .

[0030] In this embodiment, a sealing connection component is arranged between the bottom end of the lampshade 5 and the base 4 to achieve a fixed connection between the lampshade 5 and the base 4 to ensure stability while achieving a sealed connection to ensure a sealing effect of the installation.

The sealing ring, the first sealing groove 11, the annular sealing ring 8 and the second sealing groove 12 are arranged to ensure the sealing of the connection between the lampshade 5 and the base 4.

[0031] Embodiment 2:

[0032] Based on the first embodiment, the difference from the first embodiment is that:

[0033] A heat dissipation component is arranged inside the base 4, and the heat dissipation component includes an annular heat dissipation cavity 13 and a heat sink 14. The annular heat dissipation cavity 13 is opened inside the base 4, and the annular heat dissipation cavity 13 is arranged on the inner periphery of the annular mounting groove 9. Heat sinks 14 are fixedly installed at equal distances in the annular heat dissipation cavity 13. The heat sink 14 is fixedly installed in the annular heat dissipation cavity 13, and the heat sink 14 is used to dissipate heat in the inner cavity of the lampshade 5.

[0034] The heat dissipation assembly also includes a conical slot 15, a conical retaining ring 16 and a heat dissipation hole 17. The conical slot 15 is opened at the bottom end of the annular heat dissipation cavity 13, and the conical slot 15 is located in the center of the bottom of the base 4. A plurality of heat dissipation holes 17 are equidistantly opened inside the conical retaining ring 16. The plurality of heat dissipation holes 17 are connected to the annular heat dissipation cavity 13, and the conical retaining ring 16 is clamped with the conical slot 15.

[0035] A horizontal bar 18 is fixedly installed at the center of the conical clamping ring 16. By setting the horizontal bar 18, the disassembly of the conical clamping ring 16 is convenient. During the disassembly process, the conical clamping ring 16 can be directly pulled out of the conical groove 15 by pulling the horizontal bar 18, and the heat dissipation hole 17 can be cleaned to ensure the heat dissipation effect.

[0036] In this embodiment, a heat dissipation component is arranged on the base 4 to achieve heat dissipation treatment of the heat generated by the chip 2 in the inner cavity of the lampshade 5, thereby improving the heat dissipation efficiency, reducing the impact of thermal saturation on the chip 2, and maintaining its luminous efficiency. The heat sink 14 arranged evenly in the annular heat dissipation cavity 13 opened inside the base 4 is used to absorb the heat in the inner cavity of the lampshade 5, and finally the heat is discharged to the outside through the heat dissipation holes 17 located at the bottom of the heat sink 14. Through the clamping setting between the conical slot 15 and the conical clamping ring 16, the heat dissipation holes 17 on the conical clamping ring 16 are used to filter the outside of the annular heat dissipation cavity 13, and the heat dissipation treatment of the heat sink 14 can be achieved through the heat dissipation holes 17, which facilitates the separate disassembly and assembly of the conical clamping ring 16 and the cleaning of the heat dissipation holes 17 to avoid dust and impurities clogging the heat dissipation holes 17 and affecting the heat dissipation effect.

[0037] Working principle: First, install the bottom end of the lampshade 5 corresponding to the annular mounting groove 9, so that the bottom end of the lampshade 5 is connected with the inner thread 6 and the outer thread 10, and the bottom end of the lampshade 5 is rotated into the annular mounting groove 9, so as to achieve the stability of the installation between the lampshade 5 and the base 4, and achieve a preliminary sealing effect. During the thread rotation between the inner thread 6 and the outer thread 10, the sealing ring 7 is rotated into the first sealing groove 11, and is connected with the inner side wall of the first sealing groove 11. Finally, when the lampshade 5 is tightened, the annular sealing ring 8 is rotated into the second sealing groove 12, so that the outer side wall of the annular sealing ring 8 is in conflict with the inner side wall of the second sealing groove 12, so as to strengthen the sealing of the lampshade 5 installation and ensure the sealing effect.

[0038] When the chip 2 emits light, it reflects light through the reflective sheet 3, and the diamond-shaped grooves on the outside of the reflective sheet 3 increase the reflective effect, thereby increasing the brightness of the lamp bead. In addition to dissipating a part of the heat generated by the chip 2 through the lampshade 5, the rest is dissipated through the heat dissipation component on the base 4. The heat sink 14 in the annular heat dissipation cavity 13 absorbs the heat in the inner cavity of the lampshade 5, and finally the heat is dissipated to the outside through the heat dissipation holes 17. By disassembling the conical retaining ring 16, the heat dissipation holes 17 can be cleaned separately to ensure the filtering and heat dissipation effects, thereby improving the heat dissipation efficiency of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
