[0003] After searching, the Chinese patent application number: 201810515190.9 discloses an LED lamp, including a base and a lampshade, the lampshade is detachably connected to the bottom of the base, a No. 1 LED lamp bead is fixedly arranged on the lower surface of the base, a fixing bracket is fixedly welded on the upper surface of the base, an atmosphere lamp is fixedly connected to the outer wall surface of the lampshade, and a groove is fixedly arranged in the middle of the lower surface of the lampshade.
