[0023] Optionally, the female terminal 601 is surface-mounted on the light source substrate 3 by reflow soldering, and the bottom of the female terminal 601 does not exceed the top of the light source substrate 3. This design makes it easier for the light source substrate 3 to be in close contact with the top of the lampshade 1, and makes it easier for heat to be dissipated to the outside through the lampshade 1, thereby improving the heat dissipation effect.

[0024] In some embodiments, referring to FIG. 4 , the lampshade 1 includes an integrally molded shade body 101, an attachment member 103 connected to the top of the shade body 101, and further includes an end cap 102 connected to the end of the shade body 101, the attachment member 103 is inserted into the accommodating chamber and detachably connected to the base 2, the shade body 101 has an attachment passage 107 opened along a first path, the first path is parallel to the longitudinal axis of the shade body 101, the end cap 102 closes the end of the attachment passage 107, and the light source substrate 3 is arranged in the attachment passage 107.

[0025] The light source board 3 is inserted through the opening of the mounting passage 107 and connected to the shade body 101, then the end cap 102 is connected to the shade body 101, and the mounting passage 107 is closed to complete the assembly of the lampshade 1. The mounting member 103 is inserted into the receiving chamber and connected to the base 2, thereby realizing a fixed connection between the lampshade 1 and the base 2. In this embodiment, the mounting member 103 is inserted into the receiving chamber and connected to the base 2, and the light source board 3 is provided in the mounting passage 107, thereby ensuring that the light source board 3 is in a closed environment and is not affected by the temperature or humidity of the external environment. In addition, inserting the mounting member 103 into the receiving chamber not only increases the contact area with the base 2, but also allows the shade body 101 to abut against the base 2, improving the sealing performance.

[0026] Specifically, an escape hole is formed in the shade body 101, and the female terminal 601 in the light source board 3 is inserted into the male terminal 602 through the escape hole.

[0027] Alternatively, the light source board 3 may be screwed, engaged, or plugged into the shade body 101 .

[0033] The escape groove 105 reduces the contact area with the shade body 101 when the light source board 3 is inserted into the mounting groove, thereby reducing frictional resistance and preventing damage to the light source board 3. In addition, the escape groove 105 forms an interval space with the light source board 3 in the up-down direction, which is also advantageous for heat dissipation of the light source board 3.

[0037] The stopper bump 104 is inserted into the stopper groove of the driver cover 501, and not only serves to position the driver cover 501 when the driver cover 501 is installed, but also serves as a stopper for the driver cover 501, thereby improving the robustness of the connection between the driver cover 501 and the lampshade 1.

[0038] Optionally, a relief groove 105 is formed at the bottom of the stopper bump 104 and communicates with the mounting passage 107 .

[0039] Furthermore, the stopper bumps 104 extend along the longitudinal direction of the lampshade 1, improving the strength and rigidity of the lampshade 1.
