Background

Due to the popularization of personal computers and the advancement of information technology, the functions and roles of personal computers are no longer simply used as business machines, and are commonly used as multimedia playing devices and important entertainment devices in cooperation with abundant peripheral devices and high-definition video output devices.

At present, the shells or cases of a plurality of personal computers are made of transparent materials (such as acrylic), or are in hollow structures, and are matched with multicolor light-emitting diode (LED) lamp bars or full-color LED lamp beads, so that the personal computers have rich and colorful appearances.

In order to generate dynamic and color-variable light-emitting effects, one of the methods of the existing personal computers is to install a multicolor light-emitting diode, a light bar or a full-color LED lamp bead on a computer fan. However, in the prior art, the light emitting diodes are mainly installed on the fan frame or the ribs of the fan frame of the heat dissipation fan, and the light generated by the light emitting diodes is directly irradiated on the fan blades of the fan, so as to obtain the heat dissipation fan with a light emitting effect.

Generally, the light guiding ring of the fan is fixed to the fan frame through screws. However, the fixing of the light guiding ring by the screw means inevitably requires forming a hole in the fan case, and the hole may not only destroy the beauty of the fan case, but also cause a problem of light leakage.
