<p>PROBLEM TO BE SOLVED: To provide a light source unit capable of suppressing reduction in luminous efficiency while reproducing a correlation color temperature of a wide range or fulfilling user's comfort and to provide light fixtures.SOLUTION: The light source unit includes: three kinds of white light sources; and a control part. The three kinds of white light sources have chromaticity coordinates within a domain of definition of a correlation color temperature and irradiates downward. Correlation color temperatures of the three kinds of white light sources are mutually different. The control part is capable of controlling light intensity for each of the three kinds of white light sources.</p> |
