The side of the lamp cover 30 is provided with a second threading hole 303 which is communicated with the inner cavity of the lamp cover 30 and is used for the threading of the conducting wire 40, so that the conducting wire 40 led out from the wire outlet slot 101 of the lamp holder 10 sequentially passes through the first threading hole 2011 of the lamp cover 20 and the second threading hole 303 of the lamp cover 30, and the wiring of the conducting wire 40 are more convenient.

The outer side wall of the second threading hole 303 is provided with an orifice protrusion 304, and the orifice protrusion 304 can strengthen the structural strength of the lamp cover 30 and the second threading hole 303. When the wire 40 passes through the second threading hole 303, a sealing connector 305 for installing the wire 40 is configured on the second threading hole 303, and the sealing connector 305 is matched with a protruding part on the outer side wall of the second threading hole 303 so as to realize the sealing and waterproof effects of the wire 40 which is connected on the lamp cover 30 in a penetrating way.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
