LIGHT SOURCE DEVICE

WIPO Patent Application WO/2023/112593

A1

Provided is a light source device capable of radiating light toned in a predetermined color. This light source device comprises: a plurality of light emission units each including a light emission surface; an optical member including one or a plurality of first regions in which light of a first chromaticity can be extracted and one or a plurality of second regions in which light of a second chromaticity different from the first chromaticity can be extracted, and which transmits or allows passage of light emitted by the light emission units; a first movement mechanism that causes the plurality of light emission units and the optical member to make a relative movement such that the light emission surfaces and the optical member face each other; and a control unit including a light emission control unit that controls the light emission of each of the plurality of light emission units and a first movement control unit that controls the operation of the first movement mechanism. The light emission control unit performs control to cause each of the plurality of light emission units to emit light within a predetermined period. The first movement control unit performs control to cause the plurality of light emission units and the optical member to make a relative movement within a predetermined period.
