Abstract
In a lightable fan structure for dissipating heat, a circuit board is arranged in a fan body, and the circuit board is sequentially provided with a first light-guiding frame and a second light-guiding frame, and the circuit board is provide with a plurality of side-light lighting elements. Every two side-light lighting elements is reversely arranged and spaced on a rim of the circuit board. A bottom of the first light-guiding frame is annually provided with a lighting reflection layer, and the side-light lighting elements are arranged below the lighting reflection layer. The lighting reflection layer reflects light sources of the side-light lighting elements to pass through an edge and a top of the first light-guiding frame and the second light-guiding frame, thereby uniformly scattering and forming a circular light source.
