The light guide element is generally made of a light guide block or a light guide fiber. The light guide block can be embedded in the light transmission port of the fan blade and correspond to the light emitting surface of the LED. If it is a light guide fiber, one end needs to be close to the LED light source, and the other end can be arranged as needed. The light entering the light guide element is transmitted by using the total reflection principle of light inside the light guide element. Taking the optical fiber as an example, the optical fiber is composed of a fiber core with a high refractive index and a cladding with a low refractive index. When the light propagates in the fiber core, as long as the incident angle meets certain conditions, the light will be totally reflected at the interface between the fiber core and the cladding, thereby transmitting along the optical fiber axis.

However, the end connected with the LED lamp is only connected by interference fit, and is not effectively limited. Since the rotating speed of the fan is fast, a large vibration is generated. Under high-frequency vibration, the part connected by interference fit has the risk of falling off, which will cause the failure of the light guide structure. In addition, under high-frequency vibration, the part connected with the LED lamp is easy to collide with the LED lamp, causing damage to the LED lamp.
