  • Patent number: 10674122
    Abstract: A light source unit of the disclosure includes a plurality of light source sections, a light quantity detector, and a controller. The plurality of light source sections emit rays of colors different from each other. The light quantity detector receives a plurality of color rays emitted by the plurality of light source sections as spatially common light.
