• a fan body;
• wherein the fan body comprises a fan blade structure, light guide elements and an LED module;
• wherein the fan blade structure comprises a central hub and blades extending outward from an outer wall of the central hub;
• wherein the central hub defines a cavity, and each of the blades comprises a first surface and a second surface disposed opposite to the first surface;
• wherein a first end of each of the light guide elements is away from the central hub, the light guide elements comprises light-emitting points and light-receiving points, and each of the light guide elements extends along the first surface of a corresponding one of the blades to form a corresponding one of the light-emitting points;
• wherein the first surface of each of the blades is an arc-shaped curved surface, and each of the light guide elements extends along a bending direction of the arc-shaped curved surface of the corresponding one of the blades;
• wherein each of the light-receiving points is disposed on a second end of a corresponding one of the light guide elements, and the second end of each of the light guide elements faces the central hub;
• wherein the LED module is accommodated in the cavity, the LED module comprises LED lamp beads, the LED lamp beads are one-to-one corresponding to the light-receiving points of the light guide elements, and the light-receiving points are configured to receive light emitted by the LED lamp beads.
