Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 2, the LED lamp at least includes a lamp body 1 and a lamp holder 2 which are rotatably connected with each other, a mounting cavity 11 is provided at one axial end of the lamp body 1, the lamp holder 2 is partially inserted into the mounting cavity 11, the lamp holder 2 includes an annular groove 21 which is located at the circumferential side of the lamp holder and is circumferentially arranged in a circle, a threaded through hole 12 is provided at the side of the lamp body 1, a locking screw 3 is inserted into the threaded through hole 12 in a thread-fit manner, and one end of the locking screw 3 is inserted into the annular groove 21. When the end of the locking screw 3 is abutted against the bottom of the annular groove 21, the lamp body 1 and the lamp holder 2 are locked and cannot rotate relatively; when the locking screw 3 is loosened, a rotation between the lamp body 1 and the lamp socket 2 can occur. Since the locking screw 3 is inserted into the annular groove 21, the relative axial movement of the lamp body 1 and the lamp socket 2 can be restricted, and the lamp body 1 can be prevented from being separated from the lamp socket 2. Specifically, the groove width of the annular groove 21 is the same as the diameter of the locking screw 3, so that the axial movement of the lamp body 1 and the lamp holder 2 is prevented, and the structure of the LED lamp is stable. In a preferred embodiment, the locking screw 3 is a thumb screw, which is easily adjusted manually by the user. The lamp base 2 is made of hard plastic so as not to be worn by the locking screw 3.

A sealing ring 4 is arranged between the lamp body 1 and the lamp holder 2, and the lamp body 1 and the sealing ring 4, and the lamp holder 2 and the sealing ring 4 are in interference fit. The sealing ring 4 improves the sealing performance of the LED lamp, prevents an internal circuit from entering water or dust, and prolongs the service life of the LED lamp outdoors. When the lamp body 1 and the lamp holder 2 rotate relatively, under the action of friction force generated by the sealing ring 4, the lamp body 1 and the lamp holder 2 can rotate to any angle and keep relatively fixed, and the friction resistance during rotation improves the texture of an LED lamp product. In a preferred embodiment, the distance between the sealing ring 4 and the bottom of the mounting cavity 11 is smaller than the distance between the annular groove 21 and the bottom of the mounting cavity 11, so that external pollutants can be prevented from entering the LED lamp from the gap between the threaded through hole 12 and the locking screw 3. The sealing ring 4 is arranged at the end part of the lamp holder 2, so that the length of the lamp holder 2 can be set to be shorter, and the structure of the LED lamp is more compact. The lamp holder 2 is provided with a sealing groove 22 for the sealing ring 4 to be placed in a matching manner, so that the sealing groove 22 is prevented from falling off and the sealing effect is prevented from being damaged.

The lamp body 1 comprises a lamp body base 13 and a lampshade 14, the installation cavity 11 is arranged on the lamp body base 13, the lamp body base 13 is provided with an LED light source 15, the lampshade 14 is fixedly connected on the lamp body base 13 and encloses an accommodating space 16 with the lamp body base 13, and the LED light source 15 is positioned in the accommodating space 16. The lamp body base 13 is provided with a plurality of radiating fins 17 on one side different from the LED light source 15, and the radiating fins 17 can prevent the temperature of the LED lamp from being overhigh and prolong the service life. The lamp holder 2, the lamp body seat 13 and the lampshade 14 are mutually independent in structure and simple to disassemble and assemble, so that subsequent maintenance and replacement are facilitated. The lampshade 14 and the lamp body base 13 are locked through screws, and the sealing gasket 7 is arranged between the lampshade 14 and the lamp body base 13, so that external pollutants are prevented from entering the LED lamp through a gap between the lampshade 14 and the lamp body base 13.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
