The invention discloses a novel LED desk lamp which comprises a base and a gooseneck pipe fixedly mounted on the middle portion of the surface of the base. The tail end of the gooseneck pipe is fixedly connected with a lamp holder and a lampshade. The lampholder and an LED lamp bulb are connected through threads. The LED lamp bulb is located in the lampshade. First mosquito-repellent incense sachets are glued to the inner side wall of the lampshade. A cavity is formed in one side of the base and communicates with the outside through an open end. The position, away from the open end, of the interior of the cavity is fixedly connected with a motor. The output end of the motor is connected with an output shaft in a sleeeving mode. The tail end of the output shaft is fixedly connected with fanblades. A second mosquito-repellent incense sachet is glued to the position, close to the open end, of the bottom of the cavity. A groove is formed in the surface of the base, and communicates with the cavity. The top and the bottom of the groove are fixedly connected with heat conduction sheets, and a PTC heating body is arranged between the two heat conduction sheets. A first switch, a second switch and a third switch are embedded in the surface of the base. The novel LED desk lamp provided by the invention is reasonable in structure and novel in design and deserves to be popularized.
