Meanwhile, each LED lamp bead is surrounded by three steel needles and three ion pushing holes, each steel needle is also surrounded by three LED lamp beads and three ion pushing holes, and the three steel needles and the three LED lamp beads are surrounded around each ion pushing hole, so that the peripheries of the LED lamp beads and the steel needles are all provided with air flows penetrating out of the ion pushing holes to act on the air flows, but not only one side of the air flows acts on the air flows, and therefore the conversion efficiency of the negative ions is higher.

Further setting: the lamp shade is arranged on the base and used for shielding the base, and a plurality of spiral air guide holes are formed in the bottom of the lamp shade.

By adopting the technical scheme, the lampshade can protect the base, and the circuit and the devices on the circuit are prevented from being damaged by external sundries or organisms falling on the base. In addition, the lamp shade can avoid the light source that LED lamp pearl sent to penetrate directly to the below, and the light that the pointolite sent is beaten on the lamp shade, and the lamp shade scatters again for light is softer.
