Light guide fan unit

Abstract

The invention discloses a light guide type fan device. The light guide type fan device comprises a base, a bracket arranged above the base, a fan arranged on the base, a light source arranged on the bracket, and a light guide component; the light guide component is provided with a receiving section and an extending section; the receiving section is fixed to the surface of a hub of the fan and provided with a receiving surface for receiving light from the light source; the extending section extends from the receiving section, is located outside the hub and extends over a distance in the radialdirection; and a light-emitting surface facing one of fan blades is arranged on one side of the extending section and is used for guiding light received by the receiving section to the blade via the light-emitting surface. When the fan rotates, the light guided to one of the fan blades by the light guide component will produce an annular light-emitting effect on human eyes.

Description

technical field [0001] The present invention relates to a structure of a light-emitting fan device, in particular to a light-guiding fan device that utilizes a light-guiding element (such as an optical fiber) to guide light. Background technique [0002] Existing light-emitting fan devices, especially light-emitting fan devices integrated in heat dissipation modules, have come out in various structures. The basic structure of these light-emitting fan devices includes a frame base, a fan and at least one light-emitting diode arranged on the frame base. The light-emitting diode can be optionally arranged on the frame or the fan, and can produce a predetermined light-emitting effect, such as a halo effect, under the control of a control circuit. For such luminous fan devices, please refer to Taiwan Announcements 566835, M290267, M241948 and M312188. [0003] Recently, there is still a light-guiding fan device, such as the Chinese Taiwan announcement I464326, which utilizes a ...

Problems solved by technology

[0004] Furthermore, although the front end of the light guide in this type of light guide fan device forms an oblique cut to introduce more light, the diameter of the end port is so small that it actually leads to the light guide. The light from the guide or one of the leaves is so limited that the resulting luminous effect is not conspicuous enough

[0005] In addition, although the light of the above-mentioned light-emitting element can change color with the working temperature, the actual working temperature may be constant or not change much, so the light color change displayed is actually quite limited, so that the luminous effect produced is lower than that of light. Insufficient in color change
