摘要
The present invention provides a white light LED package structure and a white light source system, which includes a substrate, an LED chip, and a wavelength conversion material layer. The peak emission wavelength of the LED chip is between 400 nm and 425 nm; the peak emission wavelength of the wavelength conversion material layer is between 440 nm and 700 nm, and the wavelength conversion material layer absorbs light emitted from the LED chip and emits a white light source; and the emission spectrum of the white light source is set as P(λ), the emission spectrum of a blackbody radiation having the same color temperature as the white light source is S(λ), P(λmax) is the maximum light intensity within 380-780 nm, S(λmax) is the maximum light intensity of the blackbody radiation within 380-780 nm, D(λ) is a difference between the spectrum of the white light LED and the spectrum of the blackbody radiation, and within 510-610 nm, the white light source satisfies: D(λ)=P(λ)/P(λmax)−S(W)/S(λmax), −0.15D(λ)0.15.
