LED Lighting Preference for Different Color Objects and Light Sources Combinations
Till now, few of works have focused on modeling the LED lighting preference for different color objects and light sources combinations. 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 bunch of monochromatic flowers(yellow, purple, green, blue, red, orange, pink and mint green)which were respectively illuminated by five LED light sources with different correlated color temperatures(CCTs,2500K, 3500K, 4500K, 5500K and 6500K).And the spectral reflectances of the flowers were measured and the dominant wavelength of the colors were calculated. Afterwards, 6 kinds of flowers (yellow, purple, green, blue, red and orange) 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 (pink and mint green) and the corresponding subjective scores were used as testing samples and the experimental results showed that the perdition error of the proposed method is only around 3.5%.
