Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a LED lamp dustproof and waterproof structure, includes lamp area 1, connects electrical socket 2 and plug 3, and electrical socket 2 is installed to the right part in lamp area 1, and electrical socket 2's right side is equipped with plug 3, and slot 4 has been seted up to electrical socket 2's inside, and multiunit spout 5 has been seted up in the outside that electrical socket 2's inside is located slot 4, and the inside slip of spout 5 has inlayed slider 6, and trapezoidal groove 9 has been seted up in plug 3's the outside, and the size of slot 4 and plug 3's size phase-match.
