The invention discloses an LED lamp. The LED lamp comprises an LED lamp main body. Cooling fins are fixedly connected to the upper end of the LED lamp main body, and the lower end of the LED lamp mainbody is provided with a fixing device. A transparent lens is inlaid into the front surface of the LED lamp main body, and a rotating disc is arranged inside the LED lamp main body. A brush handle isarranged at the front side of the transparent lens. Sliding grooves are formed in the two sides of the brush handle. According to the LED lamp, multiple functional LED lamp bodies are inlaid into therotating disc, the rotating disc rotates to adjust and control which functional LED lamp bodies to be used, and multifunctionality of the LED lamp main body is greatly enhanced; the brush handle is connected with the LED lamp main body in a sliding manner, so that dust on the transparent lens is cleared, and furthermore, cleanliness of the front surface of the LED lamp main body is maintained; airinflation or air exhaust is conducted on a suction disc through a minisize vacuum pump, so that mounting or dismounting of the LED lamp is achieved; heat is transmitted to the cooling fins through aheat conduction block and emitted to the outside through the cooling fins, and furthermore, heat dissipation performance of the LED lamp main body is greatly improved; and the LED lamp is suitable forbeing applied and popularized.
