[0020] Its diffusion cover is mainly a milky white ABC material structure body, which is used to remove the shadow at the bottom of the lamp shade and make the overall light effect of the lamp shade evenly diffused.

[0021] Its base is mainly used to connect structures such as the heat dissipation aluminum member and the lamp bead board, and it is a zinc alloy structure body with dimensions: diameter 65X height 4mm.

[0022] The upper connecting member is used to fix the inner lamp shade and connect the heat dissipation aluminum member, and press the diffusion cover tightly, fix the button switch and hold the upper end of the driving circuit board, and it is a zinc alloy structure body. Dimensions: length 28X width 27X height 16mm.

[0023] An installation through hole 13 is opened on the side wall of the lamp body outer cover 1, a connecting piece gasket 22 is penetrated in the installation through hole 13, a full-thread pipe 14 is penetrated in the connecting piece gasket, the inner end of the full-thread pipe 14 is connected and positioned by a nut, a double-layer cover connecting piece 19 is provided outside the installation through hole 13, the full-thread pipe 14 passes through the double-layer cover connecting piece 19, a buckle avoidance groove 23 is opened on the inner side wall of the double-layer cover connecting piece 19, a clamping position protrusion 24 is integrally formed on the outer wall of the connecting piece gasket 22, the clamping position protrusion 24 is located in the buckle avoidance groove 23, and the connecting piece gasket can rotate in the double-layer cover connecting piece, and at this time the clamping position protrusion 24 moves and is limited in the buckle avoidance groove 23.

[0024] In this embodiment, by connecting the connecting piece gasket with the double-layer cover connecting piece, and at the same time passing the full-thread pipe through and positioning the inner end by a nut, the stability and reliability of the connection can be ensured.

[0025] In this embodiment, a conductive cable 17 is fixedly arranged inside the full-tooth tube 14.
