Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 318)

Abstract

Objective Color rending property of light source will have effect on the color showing of the irradiated object, affecting the task of color identification. The experiment was developed to supply reference gist for illuminance ergonomics design. Methods Four light sources with different color rending index (CRI) were chosen. The color tasks of comparison and fast identification were designed. The data of right ratio and error degree were analyzed. Results When light source’s CRI is above 70, it will not have evident effect on color tasks of identification and comparison. Conclusion Light source’s CRI should be above 70. Special CRI should be taken into account besides the average CRI.
