Abstract
PURPOSE: To beautifully show the flesh color of Japanese, by setting the chromaticity point of the luminous color of a fluorescent lamp by the combination of the luminous spectrum of specified luminous peak wave lengths within the specified ranges of a UV chromaticity coordinate system.
CONSTITUTION: The chromaticity point of the luminous color of a fluorescent lamp by the combinatin of luminous spectrum, which luminous peak wave lengths each range over near 450n m, near 540n m and 610n m, is set within a chromaticity range (An oblique line in the figure) surrounded by each point of (u=0.2080, v=0.3204), (u=0.2120, v=0.3300), (u=0.2110, v=0.3260), (u=0.2116, v= 0.3280), (u=0.2120, v=0.3340), (u=0.2095, v=0.3300), (u=0.2084, v= 0.3260), (u=0.2086, v=0.3280) of a UV chromaticity coordinate system. Since the facial color of Japanese is beautifully shown in a range A in the figure and the flesh color of the hands of Japanese in a range B, the facial color and the flesh color of the hands of Japanese can finely be displayed.
