基于物体色彩差异的白光LED照明喜好研究
LED Lighting Preference for Different Color Objects and Light Sources Combinations
摘要
Abstract
In this paper, the correlation between human subjective preference for LED lighting and the combination of color objects and lights sources are discussed. In the psychophysical experiments, one hundred observers with normal color vision evaluated 8 bunches of monochromatic flowers which were respectively illuminated by five LED light sources with different correlated color temperatures. And the spectral reflectance of the flowers was measured and the dominant wavelengths of the colors were calculated. Afterwards, 6 kinds of flowers and the corresponding subjective scores were used as modeling samples. A two-dimensional curved surface fitting method was developed to fit the correlation between human subjective preference for LED lighting and the combination of color objects and lights sources. To verify the proposed method, the other two kinds of flowers and the corresponding subjective scores were used as testing samples and the experimental results showed that the training and final predicting error of the proposed method are only around 0. 26% and 3. 5%, respectively.关键词
