Abstract: A luminous fan includes a fan frame, a main circuit board, a light guide element and a light-guiding impeller. The main circuit board is disposed on a bracket of the fan frame and includes a first light-emitting element. The light guide element is located over the main circuit board, and includes a light input surface and light output surface. A light guide post is disposed on the light input surface. A reflective structure is formed on the light output surface. The light-guiding impeller is pivotally coupled to the bracket. The first light-emitting element emits a first light beam. After the first light beam is transmitted to the reflective structure through the light guide post, the first light beam is reflected by the at least one reflective structure and diffused toward a middle region of the light guide element.

Abstract: A luminous fan includes a fan frame, a base portion, an illumination module and a light-guiding impeller. The light-guiding impeller is pivotally coupled to the base portion. The illumination module is disposed within a hub of the light-guiding impeller. The illumination module emits a light beam in a direction toward blades of the light-guiding impeller. Moreover, the light beam is projected to the lateral part of the hub.
