Abstract: A spotlight structure includes a main body, a waterproof front cover, and a waterproof rear cover. A front cavity and a rear cavity are arranged in the main body. A focusing component, a spotlight adjusting component and a color temperature adjusting component are arranged in the cavities. A screw thread is arranged on the outer walls of the front end and the rear end of the main body. A dovetail groove is arranged at the root of the screw thread. An O-ring is arranged on the dovetail groove. An edge of the waterproof front cover adjacent to the O-ring and an edge of the waterproof rear cover adjacent to the O-ring are a beveled edge, respectively. The waterproof front cover is threaded with the front end of the main body, and the waterproof rear cover is threaded with the rear end of the main body.
