Abstract

A shining fan structure for displaying images of patterns or characters by reflection mainly includes a fan. A plurality of blades of the fan are provided with reflective patterns or characters. Light-emitting elements are provided on the periphery of the fan base. Each light-emitting element is angled to directly irradiate the front of the blade. When the fan rotates, the light-emitting elements provided on the periphery of the base irradiate the patterns or characters provided on the blades with the lightening frequency being synchronous with or different from the rotation speed of the fan, a shining effect can be seen from the front or side of the fan by reflection or transmission.

Claims

1. A shining fan structure for displaying images, comprising:

a fan having a base and a plurality of blades, the blades of the fan provided with images;

a controlling unit; and

at least one light-emitting element provided on the fan base and electrically connected to the controlling unit, wherein

the controlling unit controls the lightening frequency of the light-emitting element to be synchronous with or different from the rotation speed of the fan, and the light-emitting element is angled to directly irradiate the images provided on the blades.

2. The shining fan structure for displaying images according to claim 1, wherein the plurality of blades are made of transparent or translucent materials.

3. The shining fan structure for displaying images according to claim 1, wherein the images include patterns or characters.

4. The shining fan structure for displaying images according to claim 1, wherein the images are formed by any one of labels, printing products or pressing products.

5. The shining fan structure for displaying images according to claim 4, wherein the images are reflective or pervious to light.

6. The shining fan structure for displaying images according to claim 1, wherein the images are formed by molding or carving.

7. The shining fan structure for displaying images according to claim 6, wherein the images are reflective or pervious to light.

8. The shining fan structure for displaying images according to claim 1, wherein the light-emitting elements are intermediately provided on all sides of the base.

9. The shining fan structure for displaying images according to claim 1, wherein the light-emitting elements are provided on four corners of the front of the base.

10. The shining fan structure for displaying images according to claim 1, wherein the light-emitting elements are erectly provided on four corners of the front of the base.

11. The shining fan structure for displaying images according to claim 1, wherein the light-emitting elements are embedded in four corners of the base.

12. The shining fan structure for displaying images according to claim 1, wherein the controlling unit is provided on the fan base.

13. The shining fan structure for displaying images according to claim 1, wherein the light-emitting elements are light-emitting diodes.
