Description

Heat radiation fan with luminous effect and implementation method thereof

Technical Field

Background

In order to avoid the problem that the electronic device is not degraded in performance or even damaged due to the accumulation of waste heat, a heat dissipation fan is usually used to guide airflow for heat dissipation. In addition, the existing heat dissipation fan not only has heat dissipation effect, but also can be widely applied to the light emitting diode and combined with the heat dissipation fan, so that the heat dissipation fan can generate colorful visual effect while running, and further the added value of the product is improved to increase the purchase desire of consumers. Such a heat dissipation fan can be found in taiwan patent No. M444697 and U.S. patent No. US 8092155.

As can be seen from the above patents, most of the current practice is to arrange a plurality of light emitting components in the fan frame of the heat dissipation fan, so that the light emitting components are powered on to generate light to make the heat dissipation fan generate light. However, the light emitting devices are disposed in many ways, for example, the taiwan publication No. M444697 is to directly embed the light emitting devices on the frame of the heat dissipation fan, and the U.S. publication No. US8092155 is to dispose the light emitting devices on more than one flexible circuit board, and then to dispose the flexible circuit board in the air flow channel. Although both methods can achieve the effect of generating light, the light effect may cause uneven brightness distribution of the light source due to the shielding of the fan frame, the fan blades or other structural components, or may cause various structural problems such as discontinuous light source due to the shielding of the light source by a part of the structure. In addition, the light emitting diode has the characteristics of energy conservation, power saving, rich color gamut, high light emitting efficiency and the like, creates thousands of colors, and does not have due visual effect in the product.

Therefore, there is a need for an improved heat dissipation fan.
