Patent abstract
According to one embodiment, there is provided a white light source system including white light sources. An absolute value of a difference between (P(λ)×V(λ))/(P(λmax1)×V(λmax1)) and (B(λ)×V(λ))/(B(λmax2)×V(λmax2)) for each of the white light sources satisfies a relational expression represented by|((P(λ)×V(λ))/(P(λmax1)×V(λmax1))−(B(λ)×V(λ))/(B(λmax2)×V(λmax2))|≤0.15
