A LED (Light-Emitting Diode) lighting fixture and a manufacturing method thereof are disclosed. The LED lighting fixture comprises a LED module generating light at a wavelength range of 300-700 nm, a lamp cover shielding the LED module, and a phosphor layer. The phosphor layer which is coated on an inner surface towards the LED module comprises at least two types of phosphor mixed at a default ratio for transforming the light of 300-700 nm in wavelength to luminary light in the wavelength range of 400-700 nm.
