Abstract

Recently, the spread of lighting using the LED is progressing. LED light source is able to reproduce most of the chromatic colour, because red, green and blue are the three primary colours of light, and these colours of LED is assembled. The chromatic colour lighting is considered that it is effective physical and psychological impact of human. Therefore, the aim of this study is to investigate the effect of chromatic colour lighting on the cognitive performance. In this experiment, the illuminance of work space was 550lx by LED light source to suit environment for cognitive performance. Lighting colours were white, red, green and blue. Memory tasks, calculate tasks, creative tasks and subjective evaluation tasks were conducted as the cognitive performance. As the results, white light colour was high score than the all other light colours in memory tasks. However, the significant difference was not observed by each light colour. Moreover, green light colour was high score than white light colour, and significant difference was observed in creative tasks. This suggests that green lighting has a positive influence on creative work.

Key Words
