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))|≤0.15The white light source system has a light emission characteristic of white light emitted by the system is continuously changed along with an elapse of time by changing a mixing ratio of light beams from the white light sources.
