Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

With reference to fig. 1 to 3, the present embodiment provides an LED lamp convenient for focusing, which includes a lamp cover assembly 1, a heat sink 2 disposed at an upper end of the lamp cover assembly 1 and adjustable up and down along an axial direction of the lamp cover assembly 1, a light emitting assembly 3 fastened at a bottom of the heat sink 2, and a fan 4 erected at a top of the heat sink 2; the lower end part of the heat radiation body 2 is exposed in the cavity of the reflecting cup 11 of the lampshade assembly 1 and is coaxially in threaded connection with the upper port of the reflecting cup 11.

Further specifically, in this embodiment, in order to facilitate timely and rapid conduction of heat generated by the light emitting component 3 through the heat sink 2, a storage cavity 21 for mounting the fan 4 is concavely arranged at the top of the heat sink 2, and air guide grooves 22 are uniformly distributed on the cavity wall of the storage cavity 21 in the circumferential direction. Thereby forming active heat dissipation to the heat dissipation body 2.

The light-emitting component 3 in the embodiment comprises a substrate fastened on the lower bottom surface of the heat radiation body 2 and an LED lamp bead arranged on the substrate, and the light-emitting component 3 and the fan 4 are both electrically connected with an external electric control device.

The lampshade assembly 1 in this embodiment includes the reflective cup 11, a casing 12 covering the reflective cup 11, and a light guide cover 13 covering a lower port of the casing 12.

In order to facilitate the matching between the heat dissipation body 2 and the reflective cup 11, the inner wall of the upper port of the reflective cup 11 is provided with an internal thread 111 matched with the external thread on the outer peripheral surface of the lower end of the heat dissipation body 2, so that the relative movement between the heat dissipation body 2 and the reflective cup 11 is realized, and the purpose of focusing the light emitting assembly 3 is achieved.
