Patent ID: 10619843

Abstract:
A heat dissipation fan structure capable of showing a pattern of light includes a circuit board, a light guide plate, a light-permeable element, and a vane assembly sequentially connected together. The circuit board is provided with a light emission unit. The vane assembly has a light-permeable wall made of a light-permeable material. The light emitted by the light emission unit is evenly diffused by the light guide plate, passes through the light-permeable element, and is rendered into a specific pattern (e.g., a decorative design and/or characters) by the light-permeable portion of the light-permeable element, wherein the light-permeable portion is shaped according to user needs. The light-permeable material of the light-permeable wall of the vane assembly allows the decorative design and/or characters of light to be seen externally. The heat dissipation fan structure, therefore, can show a pattern of light in addition to dissipating heat.
