Abstract

To provide an illumination device, a control device, and a control method enabled to perform control to cause output of each of a plurality of light sources to be constant with a more simplified temperature control circuit. There is provided an illumination device including: a plurality of light sources; a plurality of cooling units respectively provided for the light sources and respectively cooling the light sources; and a drive control unit that performs switching of control with respect to each of the light sources on the basis of a comparison between a target temperature of each of the light sources and a measured temperature of each of the light sources or an environment.
