Spectrum of D65 light source, CWF light source and A light source The color temperature of A light source (2856K) is lower than that of D65 light source (6504K), and its energy in the long-wave red zone is obviously higher than that in the short-wave blue-purple zone with overall light color of yellowish as a whole.	cache/esrj-84113.pdf	txt/esrj-84113.txt
