Problems solved by technology

However, the frame 11 of the cooling fan or the blades 131 of the fan wheel 13 are made of colored transparent plastic material, and do not have structural design for refracting or guiding light.
When the light-emitting diode 112 is irradiated on the frame 11 or each fan blade 131, the light can only be transmitted directly, and cannot produce refracted light-guiding effects and diffused light sources.
In other words, the light irradiated by the above-mentioned light emitting diode 112 is relatively small and concentrated, and its irradiated brightness is only strong at the light source, while other parts are relatively much weaker, and the overall luminance is relatively uneven. The visual effect is also poor

Abstract

The invention relates to a radiation fan with uniform lighting effect, which comprises a frame, a circuit board, a fan wheel, and a lighting unit, wherein said frame comprises one annular frame, one base plate at the center of annular frame and several ribs connecting the annular frame and base plate; the circuit board is arranged on the base plate; the fan wheel is rotationally mounted the circuit board while it comprises one fan hub and several transparent leaves on the circumference of fan hub; each leaf has several light particles, to form frog station in concave-convex shape; when the light of lighting unit is emitted to all leaves, it will generate uniform reflection.

Description

technical field [0001] The invention relates to a cooling fan, in particular to a cooling fan with a uniform luminous effect. Background technique [0002] Most of the existing cooling fans focus on the cooling function, and there is not much change in appearance or other auxiliary functions. Therefore, in order to enhance the visual experience of the cooling fan and break through the stereotype of the existing cooling fan, there is a cooling fan with luminous function. The fan was invented. [0003] Such as figure 1 , 2 As shown, the existing cooling fan includes a frame 11 , a circuit board 12 arranged in the frame 11 , and a fan wheel 13 rotatably arranged on the circuit board 12 . The inner wall of the frame 11 is provided with a plurality of installation holes 111 (only one installation hole 111 is shown in the figure), and each installation hole 111 is provided with a light emitting diode 112 . The outer peripheral surface of the fan wheel 13 is provided with a plu...
