After the protrusion is inserted into the groove, the fastening member 41 is connected to the rotating post 3311 after passing through the end cap 36, and since the end cap 36 is pressed against the step surface of the step hole, the rotating post 3311 is axially fixed in the step hole, and meanwhile, the relative rotation between the fixing base 32 and the base 33 is limited by the cooperation of the adjusting protrusion 3312 and the adjusting groove 323, thereby ensuring that the antenna 30 is locked and cannot shake; when the fastening member 41 is loosened, the rotation post 3311 is moved out of the stepped hole and at the same time, the adjustment protrusion 3312 is also moved out of the adjustment groove 323, the base 33 is rotated to adjust the antenna 30 to a desired angle, and the fastening member 41 is locked to fix the antenna 30 at the desired angle, thereby adjusting the angle of the antenna 30 or achieving folding.

In the embodiment of the present application, the casting material may be silicone rubber, epoxy resin rubber, or two-component silicone rubber, but in other embodiments, the casting material may also be other materials, which are not listed here. The pouring materials at different positions on the lighting device may be the same or different, and may be specifically selected according to actual needs, which is not limited herein.

In the present embodiment, the fastener 41 is a screw, or a bolt.

In the embodiment of the present application, as shown in fig. 1, the lighting device further includes a bracket 44, the lighting device can be hung on an external component through the bracket 44, so as to facilitate the use of the lighting device, wherein the bracket 44 is a U-shaped bracket, the U-shaped bracket is used to meet the requirement of ceiling type installation, the U-shaped bracket is connected with the driving housing 21 through a fastening member 41, and the angle of the lighting device is adjusted by rotating the fastening member 41, and the U-shaped bracket can be adjusted at least within a range of 0 ° to 90 °. The lighting equipment can also adopt a suspension rod type installation mode; the top of the driving cap 22 is provided with a G3/4 screw interface, wherein the compression nut 45 is screwed with the G3/4 screw interface and is electrically connected with an external component through the compression nut 45.
