WHITE LIGHT SOURCE AND WHITE LIGHT SOURCE SYSTEM USING SAME

摘要

The present invention provides a white light source satisfying a relational equation of - 0.2 ‰¤ P » × V » / P »max �¢ 1 × V »max �¢ 1 - B » × V » / B »max �¢ 2 × V »max �¢ 2 ‰¤ + 0.2 ,
assuming that: a light emission spectrum of the white light source is P(»); a light emission spectrum of black-body radiation having a same color temperature as that of the white light source is B(»); a spectrum of a spectral luminous efficiency is V(»); a wavelength at which P(») × V(») becomes largest is »max1; and a wavelength at which B(») × V(») becomes largest is »max2. According to the above white light source, there can be provided a white light source capable of reproducing the same light emission spectrum as that of natural light.
