Abstract

We focus on improvement of office lighting and created a color lighting system that can adjust chroma of a given hue, using full-color LEDs. Here, we developed an algorithm that calculates the optimal ratio by adjusting the intensity of the target color while retaining the target illuminance. For many colors, we investigated whether the intensity of color is acceptable for office workers by experiments using the proposed system, and we applied the color intensity obtained to uv chromaticity diagram. As a result of the experiments, the acceptable region on the chromaticity diagram showed significantly individual different and is classified into three patterns. These results indicate the acceptable region on a chromaticity diagram for office lighting.
