BASIC STUDY ON REST EFFECT OF LIGHT COLOR IN THE LED LIGHTING

Abstract

This study aims to find the proper illuminance for resting under LED color lighting environment. During the experiment, the subject`s fatigue is induced under white fluorescent lamp. And then rested under LED color lighting. Evaluations to measure rest effect are used flicker value, heart rate, self-conscious fatigue, and interior impression evaluation. As a result of the experiment, environment with the light color has the fatigue reduction effect more than white light. And, warm fluorescent lamp and pale blue color lighting LED have physiological rest and fatigue reduction effect. Dark red color lighting LED and green color lighting LED were excluded, because dark red color lighting induce activity and Green color lighting causes the psychological fatigue of an eye.
