Influence of Luminescence Pattern Stimulus of LED Colored Light on Brain Activity

Abstract

The purpose of this study is to clarify the influence of luminescence pattern stimulus of LED colored light on brain nerve system. Blood Flow of Brain and ECG and VBF and Sensory Evaluation were measured as physiological and psychological responses.
We studied four luminescence patterns of LED that combined with color and brightness and lighting condition.
Consequently, it was confirmed that blood flow of motor and sense areas was decreased, brain activity was inactivated by the luminescence pattern stimulus of LED.
In autonomic nerve activity, it was confirmed that blood flow tends to be decreased by the intense lights.
