A fundamental study on light colors of LED lighting environment

Abstract

The aim of this study is to suggest proper illumination and light colors for working in an LED lighting environment. During the first experiment, 500 [lx] was recommended by calculating 95% confidence interval of suitable illumination. During the second experiment, flicker value, distance of near point, visual acuity, and self-conscious fatigue were used for evaluating fatigue, comfort, readability and intelligibility. Results showed that colors with high purity were unsuitable for working and pale light colors with a little saturation except green are more suitable than white light color.
