Abstract: A heat dissipating fan with uniform luminosity includes a frame, a circuit board, a fan wheel and a luminous unit. The frame further includes an annular frame part, a substrate at the center of the annular frame part and a plurality of ribs being connected to the annular frame part and the substrate. The circuit board is attached to the substrate. The fan wheel further includes a fan hub and a plurality of translucidus fan blades circumferentially joined to the fan hub. Each of the fan blades has a plurality of light guiding granular spots intensively distributing at the top thereof to form a foggy and slightly uneven surface to generate a refraction effect with uniform light distribution such that the entire heat dissipating fan becomes well-lit to enhance effect of the integral sight appeal.
