    • Provided is a white light source system that reproduces the light-emission properties of sunlight having temperature colors and light-emission spectrum shapes that change over time, said white light source system being used for office and domestic illumination. As a result of the present invention, a white light source system is provided that includes a plurality of white light sources. A relationship formula is fulfilled whereby the absolute value is no more than 0.15 for the difference between P (λ) × V (λ) / P (λmax1) × V (λmax1) and (B (λ) × V (λ)) / B (λmax2) ×V (λmax2), when the light-emission spectrum for each white light source is P (λ), the light-emission spectrum for black body radiation indicating the same color temperature as each white light source is B (λ), the spectrum for spectral luminous efficiency is V (λ), the maximum wavelength for P (λ) × V (λ) is λmax1, and the maximum wavelength for B (λ) × V (λ) is λmax2. The white light source system is characterized by the light-emission properties of the white light emitted from the system continuously changing over time, as a result of changing the mixing ratio for light from a plurality of white light sources.
    • 提供一种白色光源系统,其再现具有随时间变化的温度颜色和发光光谱形状的太阳光的发光特性,所述白色光源系统用于办公室和家庭照明。 作为本发明的结果,提供了包括多个白光源的白光源系统。 对于P(λ)×V(λ)/ P(λmax1)×V(λmax1)与(B(λ)×V(λ))/ B(λmax2)×V(λmax2),当每个白光源的发光光谱是P(λ)时,指示与每个白光源相同色温的黑体辐射的发光光谱是B(λ ),光谱发光效率的光谱为V(λ),P(λ)×V(λ)的最大波长为λmax1,B(λ)×V(λ)的最大波长为λmax2。 作为改变来自多个白光源的光的混合比率的结果,白光源系统的特征在于从系统发射的白光的发光特性随时间连续变化。
