According to the color (wavelength), intensity and exposure time of the indoor lighting environment, occupants are affected by psychological stability, arousal, biological hormones, and biorhythm. To design suitable human centric lighting, it is desirable to provide light similar to daylight. Therefore, this study developed a spectrum matching method of multi LED chips for daylight spectrum. This study also evaluated the accuracy of a spectrum matching method. Using 17ch LED chips, spectrum matching with D40, D65, D80 showed an average of about 86% accuracy. |
